Embodiment Construction

[0015] The present invention is further described below.

[0016] Production fabric varieties: T / C50×50 40×40+120×90

[0017] The desizing process has the following steps in sequence: seam singeing → three-compartment hot water washing → two-compartment cold water washing → padding and oxygen bleaching working solution → steaming at 102°C for 50 minutes → four-compartment hot water washing → drying → finalizing;

[0018] The formula of the oxygen bleaching working solution used in the padding oxygen bleaching working solution step is:

Abstract

The invention relates to an oxygenase-bath alkali-free desizing process for a polyester/cotton high-count and high-density fabric. The process sequentially comprises the following steps of: sewing and singeing the fabric; washing the fabric with three-grid hot water; washing the fabric with two-grid coldwater; padding oxidation bleaching working solution; steaming at the temperature of 102 DEG C for 50 minutes; washing the fabric with four-grid hot water; drying; and shaping, wherein in the step of padding oxidation bleaching working solution, the formula of the oxidation bleaching working solution comprises 10g/L of high-efficient scouring agent HS-120B, 65g/L of 288 dispersing agent, 5g/L of scouring enzyme 188, 5g/L of wax regent WR, 10g/L of hydrogen peroxide stabilizing agent P and 14.0 to 15.0g/L of hydrogen peroxide (wherein the concentration is 33 percent). Compared with the prior art, the desized fabric has greatly improved quality, namely the handfeel is plump; the fabric surface loss ratio is low; the fabric surface whiteness is good; and the fabric has no cotton, multiple nodes and no alkaline spots.

Description

technical field [0001] The invention relates to a fabric dyeing and finishing process, in particular to an enzyme-oxygen one-bath alkali-free desizing process for polyester-cotton high-count and high-density fabrics. Background technique [0002] Polyester fiber has the characteristics of good strength, body, and poor hygroscopicity, while cotton fiber has the characteristics of softness, heat preservation, and excellent hygroscopicity. Polyester-cotton high-count and high-density fabric has a high density and a thick fabric feel. It has the advantages of both polyester and cotton fibers. The garments made are not deformed, have a body, are soft, moisture-absorbing, wear-resistant, and are comfortable to wear. They are very suitable for use in Make tooling fabrics. The warp yarns of fabrics such as cotton, viscose and synthetic fibers are mostly sizing before weaving. Sizing affects fabric wettability during dyeing and finishing and hinders chemical contact with fibers. T...
