Problems solved by technology

However, during the quality inspection of such finished fabrics, there will be unqualified performance indicators, such as low initial waterproof, oil-proof, and decontamination properties. The performance of oily and easy decontamination drops seriously. For example: after washing 10 times, the customer requires the waterproof performance of the fabric to be ≥ 80 points. In fact, after washing 10 times, the waterproof performance of the fabric is 70 points.
When such indicators are unqualified, the industry adopts re-casting for dyeing and finishing, because the three-proof and easy-to-decontamination tooling fabric is extremely water- and oil-repellent, and cannot be bleached and dyed again.
Therefore, there is currently no good way to repair the performance of such fabrics

Abstract

A method for repairing the performance of three-proof and easy-to-decontamination tooling fabrics, belonging to the technical field of functional textiles, comprising the following steps: A, mixing an auxiliary agent with water to obtain an auxiliary agent solution, and dividing the auxiliary agent solution into 3 parts, respectively Auxiliary I, Auxiliary II, Auxiliary III; said auxiliaries include isopropanol, organic fluorine finishing agent, synergist, modified fatty acid ester; In the drum, at room temperature, add Auxiliary I for 10 minutes, then add Auxiliary II for 10 minutes, then add Auxiliary III for 10 minutes, raise the temperature to 40°C, and keep it warm for 30 minutes; C. Treat the three defenses to be repaired in step B After padding, the easy-to-clean tooling fabric is stretched, dried, baked, and repeated. The invention realizes infiltration repair at relatively high temperature, and the performance after repair can fully meet the detection requirements of customers, and will not adversely affect the shade and color fastness of the fabric, and completely avoids the problems caused by re-casting blank production. Economic losses.

Description

technical field [0001] The invention belongs to the technical field of functional textiles, and relates to performance restoration of functional fabrics, in particular to a performance restoration method for three-proof and easy-to-decontaminate tooling and fabrics. The method of the invention realizes infiltration repair at a relatively high temperature, does not affect the shade and color fastness of the fabric, and completely avoids the economic loss caused by re-casting blanks for production. Background technique [0002] With the improvement of people's living standards and the acceleration of the pace of life, consumers have higher and higher requirements for the function of textile fabrics. The method quickly became widely used. The three-proof fabric is specially finished with organic fluorine finishing agent, which has the functions of oil resistance, water resistance and easy decontamination. [0003] In the dry state of wearing, the three-proof fabric has a good...
