Problems solved by technology

[0004] Although the color-fixing process disclosed in this patent can shorten the process time, the process steps are too simple to ensure that the fabric has good friction and water fastness. Therefore, designing a color-fixing process for thin suede is very necessary

Embodiment Construction

[0041] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0042] Such as figure 1 Shown, the color-fixing process of this thin suede, this color-fixing process comprises the following steps:

[0043] S1. Prepare raw materials: buy thin suede leather sold in the market as raw materials;

[0044] S2, cutting: the thin suede leather purchased on the market is cut to a size of 10 meters in length and 2 meters in width to become the base leather for color fixing;

[0045]S3. Prepare the dyeing solution: the components contained in each liter of the dyeing solution are in grams: paint color paste 3-20, sodium phenylsulfonate 1-4, polyethylene glycol 1-6, defoamer 2-6 , Ethyl methacrylate-quaternary ammonium salt copolymer 3~9, sorbitan laurate 2~8, N-vinylpyrrolidone / acrylamide copol...

Abstract

The invention provides a color fixation process of thin suede leather, aiming at solving the technical problems of an existing process that steps are too simple and relatively good friction and washing fastness and the like of fabrics cannot be guaranteed. The color fixation process of the thin suede leather, provided by the invention, comprises the following steps: S1, preparing raw materials; S2, cutting; S3, preparing dyeing liquid; S4, dyeing; S5, carrying out primary color fixation; and S6, further fixing the color. The color fixation process of the thin suede leather has the advantages that the friction and washing fastness of the dyed suede leather can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of textiles and relates to a color-fixing process, in particular to a color-fixing process for thin suede leather. Background technique [0002] Suede leather refers to the suede-like leather that is made of the front of the leather (the side that grows hair or scales) and is called nubuck; ; It is called two-layer suede made of two-layer leather buffing. Since the suede leather has no coating layer, its air permeability is better and its softness is improved, but its waterproof, dustproof and maintenance properties become worse, and the fastness of nubuck leather without grain becomes lower. Suede leather products are comfortable to wear and have good hygienic performance, but except for suede leather made by oil tanning, suede leather is easy to get dirty and difficult to clean and maintain. Mainly used for: leather shoes, leather garments, leather bags, gloves. [0003] After searching, for example, Ch...
