Problems solved by technology

[0003] At present, there are problems in traditional bleaching and brightening: chlorine bleach pollutes the operating environment of workers, and there is a prohibited halide AOX in the discharge. The residual chlorine on the fabric not only causes skin allergies, but also causes chlorine damage and yellowing of the fabric.
The whiteness produced by the general oxygen bleaching process is difficult to meet the requirements
The fluorescent whitening agent used in traditional fluorescent whitening is unsafe and harmful to the human body

Abstract

The invention discloses a method for preparing extra white lining cloth through a split-screen one-step method. Before coating a round screen, a step of coating a white paste through a round screen process is carried out; the white paste comprises nanometer mixed crystal titanium oxide, sodium hexametaphosphate and a soft type adhesive; the nanometer mixed crystal titanium oxide is formed by anatase titanium oxide and rutile titanium oxide; and the mass percent of the rutile titanium oxide accounting for the mixed crystal titanium oxide ranges from 0.5 to 2 percent. The method is carried out before coating the round screen, the step of coating the white paste through the round screen process is added, and the white paste contains the nanometer mixed crystal titanium oxide, the adhesive anda synthetic thickener, so that the lining cloth is divided into two screens in the coating process, the effects of coating and whitening are achieved at one step, water and energy conservation is realized, no chloride is discharged, and safety and environment protection are realized. The method solves the problems that the whiteness of current extra white lining cloth does not reach the standard,the bleaching and whitening processes are not environmentally friendly, and the human health can be harmed.

Description

technical field [0001] The invention relates to a processing method for textile auxiliary materials, in particular to a method for preparing extra-white interlining cloth by one-step method of dividing nets. Background technique [0002] Interlining is an important clothing accessory, which plays an important role in improving the overall wearing effect of clothing. White shirts are the most common and important garments in daily and business activities, and the whiteness of their matching interlinings is more demanding. [0003] At present, there are problems in traditional bleaching and brightening: Chlorine bleach pollutes the operating environment of workers, and there is a forbidden halide AOX in the discharge. The residual chlorine on the fabric not only causes skin allergies, but also causes chlorine damage and yellowing of the fabric. The whiteness produced by the general oxygen bleaching process is difficult to meet the requirements. The fluorescent whitening agen...
