Embodiment Construction

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] A preparation method for improving the fluorescent color fastness of fabrics, comprising the following steps;

[0021] Step 1: Pre-treatment process, take the fabric wool and put it close to the machine or flame, after burning off the hair on the surface, singeing is to burn off the hair on the surface of the fabric, so as to increase the surface finish and smoothness of the fabric, reduce the friction coefficient and improve the friction Color fastness, the fiber will...

Abstract

The invention discloses a preparation method for improving fluorescent color fastness of a fabric. The preparation method comprises the following steps of a pretreatment process, wherein a wool fabricis taken to be close to a machine and flame, after lousiness on the surface of the fabric is burned, the fabric is soaked in bleaching refining liquid containing an aqueous solution for 20 min at thetemperature of about 100 DEG C; a dyeing process, wherein after bleaching refining, the wool fabric is soaked in a dye vat containing fluorochrome, the temperature of the fluorochrome in the dye vatis 50 DEG C-60 DEG C, and in the process of stirring by adopting a tool, the p H value of dye liquor is adjusted between 3-6 for 50 min; singeing, wherein the lousiness on the surface of the fabric isburned to improve the finish degree and smooth degree of the surface of the fabric, the friction coefficient is reduced, the rubbing color fastness is improved, the bleaching refining liquid is prepared from sodium metasilicate, sodium carbonate and a scouring agent to improve the dye permeability, level dyeing, dye-uptake rate and fixation rate of the dye in the dyeing process, and the less thesurface color, on the surface of the fabric, of the dye is, the better the color fastness to rubbing and washing is.

Description

technical field [0001] The invention relates to a method for improving fluorescent color, in particular to a preparation method for improving the fluorescent color fastness of fabrics. Background technique [0002] The fluorescent color fastness of knitted nylon elastic fabric has always been very poor, especially the color of fluorescent dye as the main material. The washing fastness of the finished product is generally around 2 to 3 grades. 2 to 3 levels, which has become recognized in the industry. Although there are some color fixing agents on the market that improve the color fastness of fluorescent light, the actual effect is not good. [0003] Knitted nylon elastic fabrics are generally fixed at 70-80°C. Traditional operations believe that if fluorescent colors are fixed at such a high temperature, the fluorescent dyes will easily detach from the fabric surface, causing serious color fading and large color problems. Therefore, Basically, fluorescent colors are fixed...
