Some functions of textile products can be achieved by functional finishing of fabrics, among which the waterproof function is to endow the fabrics with waterproof properties through post finishing. The so-called waterproof finishing refers to the formation of a low surface tension structural layer on the surface of the fabric by post finishing, so as to achieve the hydrophobicity of the surface of the fabric while maintaining the original performance characteristics of the fabric. However, perfluorooctane sulfonyl compounds (PFOS) and perfluorooctanoic acid (PFOA) contained in the commonly used fluorocarbon waterproofing agents may cause problems such as bioaccumulation and impact on the ecological environment. The fluorine free waterproof agent does not contain any PFOS and PFOA, so it will not deposit in the organism and is easy to degrade. As the concept of ecology and environmental protection has become increasingly popular, fluorine free waterproof finishing agent, as a safe and environmentally friendly product, is more easily accepted by the market.
Fluorine free waterproof agent REP is a high-performance auxiliary agent synthesized from modified resin, which is suitable for waterproof and anti siphon finishing of various fabrics. The finished fabric of textile fabric has excellent waterproof and anti siphon performance, which can easily achieve 100 points of waterproof, anti siphon does not climb for 12 hours, and has good washability. The waterproof performance is still excellent after washing for many times. The fluorine free waterproof agent has simple processing technology and is easy to operate, and the dip rolling and dipping processes are applicable; It has no adverse effect on the processed fabric, and does not affect the original permeability and feel of the fabric; With good stability and compatibility, it can be used in the same bath with finishing auxiliaries such as softeners to improve its serviceability; It is safe and environmentally friendly, does not contain PFOS and PFOA, and complies with export standards.
The fluorine free waterproof agent REP with excellent waterproof and anti siphon properties and washability can be used for the anti splash, anti siphon, hydrostatic pressure resistance, and water washing coating of cellulose fiber, synthetic fiber and their blended fabrics to do the anti penetration treatment, and is applicable to the fields of webbing, gloves, hats, footwear, leather, etc.
