Embodiment Construction

[0020] The invention discloses an ultra-white fabric with high light fastness, which includes a fabric to be treated, and the ultra-white fabric with high light fastness is obtained through fluorescent whitening agent treatment and reduction bleaching during the bleaching process. The fluorescent whitening agent is mainly composed of bistriazinyl stilbene and its derivatives.

[0021] Said a kind of extra-white fabric with high light fastness, said fluorescent whitening agent mainly includes: bistriazine-based stilbene derivatives, stilbene triazole derivatives, benzoxazole derivatives one or several.

[0022] The preparation method of described a kind of high light fastness special white fabric, it comprises the following steps:

[0023] Put the fabric to be treated in the treatment bath, and add pretreatment agent BFN-07 (fatty alcohol polyoxyethylene ether mixture), hydrogen peroxide stabilizer PSL (polyacrylate and organic phosphate mixture), NaOH (sodium hydroxide ), H ...

Abstract

The invention relates to a fabric in dyeing industry, especially relates to white fabric. A high light fastness ultra-white fabric includes fabric to be treated. The bleaching process of the high light fastness ultra-white fabric is obtained by fluorescent whitening agent treatment and reduction bleaching. The fluorescent whitening agent mainly comprises derivatives of bis-triazine diphenyl ethylene. Preparation of the high light fastness ultra-white fabric includes steps of: putting the fabric to be treated into a treatment bath, adding pre-treatment agents BFN-07, hydrogen peroxide stabilizer PSL, NaOH, H2O2 in sequence, direct heating to 98 DEG C., keeping temperature for 60 minutes, lowering temperature, discharging water, neutralizing and water washing, adding the fluorescent whitening agent for treatment, and reduction bleaching or the like. The ultra-white fabric has great light fastness, meets the requirement for high-grade clothes and sport clothing, is great in hand-feeling and comfortable for wearing.

Description

technical field [0001] The invention relates to fabrics in the printing and dyeing industry, in particular to a white fabric. Background technique [0002] At present, the white fabrics provided by the market are usually bleached. However, after these fabrics are made into clothing, the fabrics are often not correct in color, and they are prone to yellowing after a period of sun exposure and washing. The industry calls this characteristic For light fastness, and for white fabrics must be rated according to industry standards. Usually high-end clothing and sportswear have high requirements for this indicator, and few fabrics can meet this requirement. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects of the existing white fabrics, and provide an extra-white fabric with high light fastness and a preparation method thereof. The whitening fabric of the invention has good light fastness, meets the requirements o...
