Embodiment 1

[0014] Using nanometer zinc oxide ZnO aqueous solution with a weight ratio of 5% as a finishing agent, the 190T polyester spun-dyed fabric is padded, pre-baked at 160°C for 2-3 minutes, melt-baked at 185°C for 2-3 minutes, and cooled. Drop the cloth, and control the walking speed of the fabric at 60m / min. After finishing, the degree of wetness was tested to be 90 points.

Embodiment 2

[0016] The above steps were repeated, the weight ratio of the nano zinc oxide ZnO aqueous solution was 6%, the pre-baking temperature was controlled to be 165° C., and the melt-baking temperature was 190° C. After finishing, the degree of wetness was tested to be 95 points.

Embodiment 3

[0018] The steps of Example 1 were repeated, and the pre-baking temperature was controlled to be 150° C., and the melt-baking temperature was 180° C. After finishing, the degree of wetness was tested to be 90 points.

Abstract

The water repellent finish process of dry fabric adopts water solution of nanometer ZnO in the concentration of 5-6 wt% as the finishing agent, and includes the steps of padding, predrying at 145-165 deg.c for 2-3 min, baking at 170-190 deg.c for 2-3 min and cooling, with the fabric running speed being controlled in about 60 m / min. By means of combining the nanometer material with small size and great surface area onto the fabric to form firm compact hydrophobic layer, the present invention reaches powerful water repelling aim.

Description

technical field [0001] The invention relates to a waterproof finishing method for fabrics, in particular to a water-repellent finishing method for dry fabrics. Background technique [0002] The purpose of waterproof finishing is mainly to endow the fabric with two aspects of water repellency (that is, non-sticking to water) and water pressure resistance. Water repellency is to make the fibers of the fabric hydrophobic through the water-splashing finishing process, and to retain the original mesh of the fabric as much as possible. Tissue, allowing air and water vapor to pass through freely, on the contrary, making water impermeable, making the fabric breathable and water-repellent. Water pressure-resistant finishing (that is, coating finishing) is a finishing that fills a waterproof substance between the yarns of the fabric and between the fibers, and applies it to the entire surface of the fabric to safely prevent the penetration of water. method. Umbrella fabric achieves ...
