Which fabric dyeing scenarios are mainly used in? Answer: High-efficiency formal-free color fixing agent HTF-658 is a textile dyeing and finishing auxiliary with a chemical composition of cationic copolymer. The core advantage is that it does not contain free formaldehyde and does not release free formaldehyde, which meets environmental protection requirements. It is mainly used for polyester, viscose, cotton and other fabrics. For these fabrics, dyeing with reactive dyes, direct dyes or fixing after printing, it can improve the soaping, washing, sweating, rubbing, ironing, and sun fastness of the dyed matter without affecting the brightness and color of the dyed matter.   Question 02-What is the biggest advantage of the high-efficiency non-aldehyde color fixing agent HTF-658 compared with ordinary aldehyde color fixing agents? Answer: The biggest advantage lies in environmental protection and safety. The product does not contain free formaldehyde and does not release free formaldehyde. It can meet the current strict requirements of the textile industry on formaldehyde content (such as the limit on formaldehyde content in textiles in national standard GB18401 -2010), avoid formaldehyde fixing agents caused by formaldehyde residues. Environmental compliance risks and do not affect the performance of dyes. Ordinary aldehyde fixing agents are prone to formaldehyde release problems, which may cause the product to fail to meet the standards and leave the factory.   Question 03- What is the reference amount of HTF-658, a high-efficiency non-aldehyde color fixing agent? Are there differences in the amount used according to different usage methods?   Answer: The amount of this product depends on the color shade of the fabric. The reference amount is divided into two methods: 0.3~0.8%(o.w. f)(based on the weight of the fabric) for the dipping method, and 3~5g/L (based on the volume of the treatment liquid). The actual amount needs to be adjusted through the sample adjustment process to ensure the best color fixation effect and avoid insufficient fastness due to insufficient amount, or excessive amount to increase costs.   Question 04- What are the packaging specifications of HTF-658, a high-efficiency non-aldehyde color fixing agent? What should I pay attention to when storing?   Answer: This product is packed in 125 kg plastic drums for easy transportation and storage. Storage must be kept at room temperature and protected from light. Strictly follow this condition. The product storage period is 1 year. If the storage environment temperature is too high, direct sunlight or improper sealing, product performance may be degraded and shelf life may be shortened.   Question 05- What is the reference amount of HTF-658, a high-efficiency non-aldehyde color fixing agent? Are there differences in the amount used according to different usage methods? Answer: The amount of this product depends on the color shade of the fabric. The reference amount is divided into two methods: 0.3~0.8%(o.w. f)(based on the weight of the fabric) for the dipping method, and 3~5g/L (based on the volume of the treatment liquid). The actual amount needs to be adjusted through the sample adjustment process to ensure the best color fixation effect and avoid insufficient fastness due to insufficient amount, or excessive amount to increase costs.   Question 06- 60% aldehyde free color fixing agent, what is the advantage compared with low solid content aldehyde free color fixing agent? Answer: Its high solid content of 60±1%(much higher than the 20%-40% level of some low-solid content products in the industry) has two major advantages: First, it is more efficient per unit dosage. Under the same fixation demand, the amount of high-solid content products is reduced, which can reduce transportation and storage costs (more active ingredients are available under the same weight, reducing transportation frequency); Second, the performance is more stable, and the proportion of impurities in the high-solid content formula is low, which can reduce the potential impact on the color and feel of the dye.     Question 07- What are the appearance and pH indicators of aldehyde free color fixing agent (60%) HTF-367? How to check during acceptance? Answer: The appearance of the product is a light yellow transparent and viscous liquid with a solid content of 60±1%, and a pH range of 7-11. During purchase acceptance, the appearance can be visually observed to see whether it conforms to the description, and at the same time, samples can be taken to test the solid content (according to GB/T 2793-2015 "Determination of Non-Volatile Matter Content in Adhesives") and pH value (according to GB/T 6368-2008 "Potentiometric Method for Determining the pH Value of Aqueous Solutions of Surfactants") to ensure that the indicators meet the standards.   Question 08-Your company's formal-free color fixing agentWhich dyes is the product suitable for fixation? Can it be used to dye fabrics with reactive turquoise dye? Answer: The product is suitable for direct dyes, reactive dyes and fixing printed fabrics. It has significant effects on fabrics dyed with reactive turquoise dyes. It can effectively improve the wet fastness of reactive turquoise dyed fabrics and solve the problem of difficult fixing and low fastness caused by reactive turquoise dyes due to molecular structural characteristics, which is one of the core application advantages of this product.     Question 09- What is the regular minimum order quantity and minimum trial quantity of formaldehyde-free color fixing agent (60%, 50%)? Answer: Based on the packaging specification of 125 kg/barrel, the regular minimum order quantity is 1-2 barrels (125-250 kg), and the minimum trial mining volume can be negotiated to 1 barrel (125 kg). During trial mining, an agreement needs to be signed to clarify the quality standards, trial mining purposes and price connection terms for subsequent batch purchases meet the company's small scale verification needs.   Question 10- If a customer requires a product to pass specific third-party testing (such as OEKO-TEX® Standard 100 certification), can the manufacturer cooperate? Answer: Manufacturers can cooperate to provide product inspection services. If customers need products to pass specific certification tests such as OEKO-TEX® Standard 100, manufacturers can sample samples and send them to designated third-party agencies (such as SGS and Tianxiang) for testing. The testing costs will be borne by both parties through negotiation (usually, the small batch testing fee is borne by the customer, and the batch purchasing fee can be negotiated and borne by the manufacturer). The testing cycle is 7-10 working days, and a test report will be provided after passing the test.     Question 11- What is the reference amount of formaldehyde-free color fixing agent (60%) HTF-367? How to choose dipping method and padding method? Answer: There are two methods for reference dosage: 0.2~0.7%(o.w. f) for dipping method (calculated based on the weight of the fabric), and 4~10g/L for padding method (calculated based on the volume of treatment liquid). The selection needs to be combined with the production process: small-batch, multi-variety fabrics are suitable for using the dipping method, which is flexible to operate; large-batch, continuously produced fabrics are suitable for using the dipping method, which is more efficient. The actual amount needs to be adjusted according to the fabric color depth and dye type. Sample adjustment.   Question 12- Two formaldehyde-free color fixing agents (50%、60%) After the treated fabric is subsequently washed, ironed and other processes, will the fixation effect be lost?   Answer: Under the premise of correct use (operating according to the recommended dosage and temperature) and sufficient fixation, the treated fabric will be washed regularly (according to the standard washing process of GB/T 3921 - 2008) and ironed (temperature ≤150℃, which meets the requirements of fabric ironing), the fixation effect will not be significantly lost. This is because the active ingredients of the two products form chemical bonds with dyes and fibers (such as electrostatic bonds and coordination bonds) rather than simple physical adsorption, and the binding force is strong. However, it should be noted that if a strong alkaline detergent (pH>10) is used for subsequent washing or long-term high temperature immersion (>80℃), some of the bonded structure may be damaged and a small amount of fastness may be reduced. Therefore, it is recommended that subsequent processes follow routine fabric care requirements and avoid extreme conditions.   Question 13- Both formane-free color fixing agent 50% and formane-free color fixing agent (60%) are marked as "formane-free". What specific environmental protection standards do they meet? Can the use of exported textiles meet international requirements? Answer: Both products meet the requirements of the national "Limits on Formaldehyde Content in Textiles"(GB 18401 - 2010) that "the formaldehyde content of textiles in direct contact with skin is ≤75mg/kg, and textiles for infants and young children are ≤20mg/kg", and no free formaldehyde is released through testing. For export scenarios, it can meet international standards such as EU REACH Regulation (formaldehyde restriction clause in Annex XVII), OEKO-TEX ® Standard 100 (formaldehyde limits for Class I-IV textiles) and U.S. CPSIA (formaldehyde requirements for children's textiles). If you need to export to a specific region during procurement, you can require the manufacturer to provide a test report corresponding to the regional environmental protection standards (such as the EU compliance report issued by SGS) to ensure that the product meets the requirements of the target market.   Question 14-When using non-aldehyde color fixing agents, what impact will it have on the fabric if you accidentally add them too much? How to remedy it? Answer: Excessive addition may cause two major problems: ① The fabric feels hard and rough, because excess fixing agent adheres to the surface of the fiber, forming a film-like substance;② Light-colored fabrics may appear dark (especially cationic fixing agents), or "floating" residues appear on dark fabrics. If excessive amount is found, the fabric can be rinsed 2-3 times immediately with warm water at 40-50 ° C (with a small amount of non-ionic detergent), each rinsing time is 10-15 minutes to remove excess fixing agent; if it has been dried, it needs to be re-soaked in warm water (with detergent) for reduction and then rinsed. After remediation, the fixation fastness needs to be re-tested to ensure that it still meets the requirements.   Question 15-What are the main types of formane-free color fixing agents on the market based on ingredients? What are the differences between different categories in application scenarios? Answer: Formaldehyde-free color fixing agents are mainly divided into three categories according to their core components: ① Cationic type (such as cationic polyamines, quaternary ammonium salts), suitable anionic dyes (reactive, direct dyes), due to their strong charge adsorption ability, are most widely used in fixing natural fiber fabrics such as cotton and linen;② Reactive type (Contains reactive groups such as epoxy groups and amino groups), can form covalent bonds with fibers and dyes, and has extremely high fixation fastness. It is suitable for high-end textiles (such as close-fitting clothing and export fabrics);③ Non-ionic (such as polyether), It has good compatibility and does not easily affect the feel of the fabric. It is often used in combination with other types and is mostly used for fabrics with high softness requirements (such as silk and wool). When purchasing, it is necessary to choose according to the dye type and fabric characteristics to avoid poor fixing effect caused by mismatch.     Question 16-If the formane-free color fixing agent is not used up in time after opening, how should it be stored to avoid performance degradation? What are the consequences of improper storage? Answer: After opening, storage must be followed in accordance with the principles of "sealing, avoiding light, and controlling temperature": ① Tighten the lid immediately. If the original bucket is damaged, transfer it to a clean and dry HDPE plastic bucket (complying with GB/T 13508-2011 standard) and seal it;② Store in a cool and ventilated place, and the temperature is controlled at 5-35 ° C to avoid direct sunlight or close to heat sources (such as boilers and heating);③ Cover it tightly after each use to prevent moisture and impurities in the air from mixing in. Improper storage may lead to: ① The active ingredients are volatilized or degraded, resulting in reduced color fixation effect;② The solution is layered and turbid (especially for products with high solid content), which cannot be used uniformly;③ The breeding of microorganisms (in a humid environment) and polluting the fabric. It is recommended to use it within 1 month after opening, and the longest time should not exceed 2 months.​

01-What is a polyamine (epichlorohydrin dimethylamine copolymer) water purifier? What is its basic principle? Answer:Polyamine (epichlorohydrin dimethylamine copolymer) water purifier is a cationic polymer. It mainly purifies water quality through the principle of charge neutrality and adsorption bridging. Pollutants such as suspended particles and colloids in water usually carry negative charges. A large number of positively charged groups on the molecular chain of polyamine water purification agents can undergo charge neutralization reactions with these negatively charged pollutants, destroying their stability and promoting them. Gather together. At the same time, polyamines have long molecular chains, which can play a bridging role between particles, connect multiple small particles into large flocs, accelerate precipitation, and achieve water purification. The relevant principles are detailed in the "Water Treatment Agents Handbook". Elaborate.   02-What types of water can polyamine water purifier treat? For example, industrial wastewater, domestic sewage or drinking water? Answer:Polyamine water purifier has a wide range of applications. In terms of industrial wastewater treatment, it has good treatment effect on wastewater with high turbidity, high chroma, and containing organic matter and heavy metal ions generated by printing and dyeing, papermaking, chemical and other industries. For example, the decoloration rate of printing and dyeing wastewater can reach more than 95%, and the removal rate of CODcr is 50%-70%, which has been verified in many academic studies such as "Synthesis of polyamine flocculants and their potential use in treating dye wastewater"; For domestic sewage, suspended solids and organic matters can be effectively removed and sewage turbidity can be reduced; during the drinking water pretreatment stage, impurities such as colloid and algae in the water can be removed, water quality can be improved, and the efficient operation of subsequent purification processes can be ensured.   03-What is the appearance and state of a polyamine water purifier? What are the requirements for storage conditions? Answer:Polyamine water purifying agents are usually colorless to light yellow transparent liquids. During storage, it is required to be stored in a sealed manner and should be placed in a dry, cool and ventilated warehouse to avoid direct sunlight and high temperature environment. The storage temperature is recommended to be controlled at 5 ℃-35 ℃. If the temperature is too high, it may lead to product degradation and performance degradation. If the temperature is too low, crystallization and solidification may occur, which will affect use. The shelf life of the product is generally 6 months (below 25 ℃). Storage as required during the shelf life can ensure stable product performance.   04-Do you need special equipment when using polyamine water purifier? What is the investment method? Answer:The use of polyamine water purifier does not necessarily require special equipment, but can be selected based on the amount of water treated and water quality. For small amounts of water, a simple intermittent dosing method can be used, and a manual metering container can be used to intermittently add the diluted polyamine water purifier to the water to be treated; for large amounts of water, continuous dosing is recommended, and a metering pump is required. The diluted polyamine water purifier (recommended dilution ratio is 1:5 - 1:10, diluted with clean water or recycled water after treatment) is continuously injected into the water treatment system at the set flow rate. No matter which method is used, it is necessary to ensure accurate control of the dosing amount to avoid affecting the treatment effect due to excessive or insufficient dosing.   05-Compared with common water purification agents such as polyacrylamide, what are the unique characteristics of polyamine water purification agents? Answer:Compared with polyacrylamide, polyamine water purification agents have three unique advantages. First, the charge density is higher. The charge density of polyamines can reach 2.5 - 3.0meq/g, and the charge density of polyacrylamides is generally 1.5 - 2.0meq/g, which makes polyamines have stronger adsorption capacity for negatively charged pollutants., and the flocculation speed is 20%-30% faster. Second, the pH has a wider range of application. Polyamines can function efficiently under water conditions of pH 4.0 - 10.0. Polyacrylamide is more suitable for neutral and alkaline water (pH 6.0 - 8.5). Polyamines reduce the complex operation of adjusting water pH. Third, in terms of biological safety, after testing, residual amine substances in water after polyamine-treated are ≤ 0.1 mg/L, which is far lower than the drinking water hygiene standard (≤ 0.5 mg/L), and can be used for drinking water pretreatment. However, polyacrylamide is limited in the application of drinking water treatment due to monomer residue problems.   06-Compared with traditional water purification agents, how much can New Haitian Company's polyamine water purification agents reduce water treatment costs for enterprises? Answer:Compared with traditional water purification agents such as polyaluminum chloride and polyacrylamide, our polyamine water purification agent has the core advantages of "low dosage and high treatment efficiency". In typical scenarios such as industrial circulating water and municipal sewage, the dosing amount can be reduced by 30%-50%, and the cost of subsequent sludge dehydration treatment can be reduced (sludge production is reduced by 20%-30%). Taking a company that processes 10,000 tons of sewage per day as an example, the comprehensive water treatment cost can be reduced by 12,000 - 20,000 yuan per month. Specific data can provide a customized cost calculation plan based on your company's water quality parameters.   07-What is the production capacity of New Haitian Company's polyamine water purifier? Can long-term stable supply be guaranteed and the risk of supply interruption be avoided? Answer: Our company has a professional production line for polyamine water purification agents with a production capacity of 15000 tons. It has passed REACH certification and NSF certification, which can meet the emergency order demand of 500 tons per time. At the same time, we have established a full-chain supply chain management system of "raw material-production-warehousing-logistics", and signed long-term strategic cooperation agreements with core raw material suppliers such as epichlorohydrin and dimethylamine. We have sufficient raw material reserves and can provide your company with "monthly scheduled and quarterly guaranteed" stable supply services, and the risk of interruption of supply is very low.   08-What is the range of key indicators such as appearance, solid content, and pH value of your company's polyamine water purifier? How to adapt to the treatment needs of different water quality? Answer: The core indicators of our company's polyamine water purifier are strictly controlled at: molecular weight 80,000 - 150,000 Da, solid content ≥50±1%, pH value4-7​、Viscosity:100-6000。For different water quality, we provide 3 customized models: ① Low molecular weight type (suitable for high-turbidity industrial wastewater, rapid flocculation and sedimentation); ② Medium molecular weight type (suitable for municipal sewage, taking into account turbidity removal and decoloration); ③ High molecular weight type (suitable for low-turbidity drinking water pretreatment to improve filtration efficiency), the optimal model can be recommended based on your company's water quality test reports (such as turbidity, COD, suspended matter concentration).   09-Will the polyamine water purifier produce harmful substances during use and affect the environment or human health? Answer: No. Polyamine water purifier itself is an environmentally friendly water treatment agent and will not produce harmful substances under normal use doses. Its degradation products are mainly small molecule amines, carbon dioxide and water, and have no secondary pollution to the environment. From the perspective of human health, when water treatment meets discharge standards, the concentration of polyamines and related degradation products remaining in water is extremely low and will not cause harm to human beings. Its safety has undergone strict toxicological tests and practical application verification., in line with relevant national environmental protection and health standards, such as the "Hygiene Standard for Drinking Water"(GB 5749 - 2022) clearly stipulates the limits of related substances that may remain in drinking water, and the polyamine water purifier fully meets the standards.   10-Xinhaitian CompanyDo you provide technical support and after-sales service?
