What is the difference between fluorine-based waterproofing agent and fluorine-free waterproofing agent? - China Garment Website_China's popular garment and fashion information platform

According to the structure of the carbon chain, it can be divided into C8, C6, and C4, collectively called the fluorine system.

C8 has excellent effects and is affordable. It has been used by major textile and leather industries many years ago. However, C8 contains PFOA (perfluorooctanoic acid and salts), PFOS (perfluorooctane sulfonyl compound) and APEO (alkylphenol polyoxyethylene). ether). PFOA, PFOS and APEO are currently difficult to degrade in the environment. They are bioaccumulative and have multiple toxicities. They have the common characteristics of persistent organic pollutants. They are considered to be new persistent environmental pollutants that are focused on research in the 21st century. Their sources It is mainly a fluorine-based waterproof and oil-repellent agent. The main component of C6 is PFHS (perfluorohexane sulfonyl compound or sulfonate), which is an ideal product to replace C8 containing PFOA and PFOS. For the textile industry, the main source of PFOA and PFOS is fluorine-based waterproofing Oil repellent. Therefore, the EU decree issued in 2006 stipulated that the content of PFOS and PFOA in textiles exported to the EU must be less than 1ug/㎡; at that time, it was difficult for C8 on the market to meet the requirements, and the PFOS and PFOA content in C6 was less than the regulations. Numerical values are generally difficult to detect, so it has been widely used instead of C8. However, in terms of effect and price, C6 is expensive, but its effect is difficult to match C8.

According to market demand, our company solemnly launches the extremely cost-effective C6 low-temperature carbon six, ZJ-560 low-temperature C6: in polyester, nylon and other chemical fiber fabrics, 125℃, the dosage is 10g/L∼20g/L (it is recommended to write the range, because the fabric The final waterproof effect will be different depending on the thickness and structure.) The initial waterproof effect can reach 100 points, and it can be treated with super washable water. After 30 times of washing, the waterproof effect reaches 90 points, and after 50 times, the waterproof effect reaches 80 points. point. Anti-siphoning for 48 hours, siphon height is 0mm, PFOA and PFOS content are absolutely lower than the newly released OEKO-TEX Standard100 limit value <1ug/㎡ on April 1, 2015. Fully compliant with international environmental testing standards.

As global environmental protection pays more and more attention, the U.S. Environmental Protection Agency has stipulated that by 2015, the use of C8 and C6 containing PFOA and PFOS will be banned worldwide, and C4 and fluorine-free will be strongly recommended. In 2015, fluorine-free will be Popularly used in the textile industry.

What is fluorine-free?

Fluorine-free, completely free of APEO, PFOA and PFOS, it is a good alternative to organic fluorine.

Fluorine-free advantages:

Can be used alone, 100% waterproof effect;

Affordable price: equivalent to the current C8 fluorine series and cheaper than the C6 fluorine series;

It also has water-repellent and washable effects: it can be used as a synergist and three-proof finishing synergist: used in the same bath as all fluorine-based three-proof products, it can significantly improve the initial water-repellent effect and washability, and the use of additives is comprehensive The cost is greatly reduced, and it is an excellent three-proof finishing enhancement additive on the market.

Our product ZJ-XR88 is fluorine-free, has high performance and price, and can meet most market demands. ZJ-XR89 is fluorine-free, highly washable, and can be washed 20 times, which can satisfy customers who require high washing times. It is especially suitable for synthetic fibers such as chemical fibers. Water-repellent finishing of fibers;

It has the effects of anti-siphoning, hydrostatic pressure resistance and anti-slurry penetration. It can be used for anti-siphoning finishing of shoe materials and is absolutely environmentally friendly;

Whether used alone or used as a synergist, it has a good water-washing resistance effect, which is different from the cross-linking agent used in the same bath as three-proof products;

Fluorine-free development trend:

In 2015, the use of C8 and C6 will be banned globally, and fluorine-free products will replace them and become a product that attracts attention in the global textile industry. It does not contain any PFOA, PFOS and APEO, has excellent waterproof effect and is washable.
