Problems solved by technology

At present, the anti-slip finishing in the market generally uses modified colloidal polysilicic acid or acrylic resin finishing agent to pad the fabric, but the finished fabric feels hard and rough, and static electricity is easily generated during the production process, and the fabric is torn. The breaking strength is greatly reduced, making it lose its use value in some aspects

Abstract

The invention relates to a preparation method of a polyester woven fabric anti-slippage finishing agent. The preparation method comprises the following steps: prepolymerizing polyethylene glycol, neopentyl glycol, isophorone diisocyanate, N-methylpyrrolidone and an aqueous zinc isoocatanoate solution, introducing a telechelic structure through adding gamma-aminopropyltriethoxysilane, adding waterto emulsify, and adding an epoxy modified organosilicon emulsion to complex. The finishing agent can effectively improve the anti-slippage effect of polyester woven fabrics, improve the tearing strength, and maximally reserve the original handle of the fabrics.

Description

technical field [0001] The invention relates to a finishing agent, in particular to an anti-slip finishing agent for polyester woven fabrics and a preparation method thereof. Background technique [0002] Polyester fabrics are widely used in clothing inner linings, clothing outerwear materials and various functional fabrics because of their advantages such as high strength, good wear resistance, and good shape retention. With the continuous emergence of new textile materials, light, soft, and medium-density polyester woven fabrics are favored by clothing fabric manufacturers, and the market demand continues to increase, but at the same time it also faces some urgent problems, one of which is due to Due to the smoothness of polyester fibers, when used as clothing fabrics (especially thin fabrics), under the action of external force, the yarn at the seam is easy to slip and cause the fabric to crack. The appearance of flaws will not only affect the appearance of clothing, but...
