Embodiment 1

[0040] A method adopting fiber chemical denaturation, paint dyeing and overflow sand washing, fiber products are subjected to cationic chemical denaturation reaction to cellulose fibers under non-alkaline conditions through a cationic denaturant, and then subjected to paint dyeing and overflow sand washing treatment, Make the fiber products form the traditional stone-washed distressed effect.

[0041] The method includes the following processes:

[0042] Gray cloth---scouring---chemical denaturation---paint dyeing---sand washing treatment---soft drawing---shrinking---sorting---finished product.

[0043] 1) The formula of the working solution of the chemical denaturation and paint dyeing is:

[0044] Cationic denaturant: 1-3% (o.w.f, to product weight)

[0045] Compound enzyme: 5-8% (o.w.f, to product weight)

[0046] Hydrogen peroxide: 4-8 grams per liter of working fluid

[0047] Dispersant: 1-2 grams per liter of working fluid

[0048] 2) The cationic denaturant adopts ...

Embodiment 2

[0060] The application of the method of chemical denaturation of fibers, paint dyeing and overflow sand washing in garment dyeing includes the following steps:

[0061] 1) Chemical denaturation and dyeing in the same bath:

[0062] Working fluid formula:

[0063] Highly active quaternary ammonium cationic etherifying agent, 1-3% (o.w.f); its effective active substance content is ≥69.5%, 1,3 dichlorohydrin≤15ppm, epichlorohydrin≤5ppm, 10% of cationic denaturant The pH value of the aqueous solution is 5-7;

[0064] Paint, X%

[0065] Bath ratio: 1:12

[0066] The method of chemical denaturation and dyeing in the same bath is as follows: put the dry fabric and the working solution into the equipment and circulate it for 1-2 minutes under the condition of 30-40°C, and then denature and dye for 10 minutes under the condition of 75-80°C. -20 minutes, wash with water once, the washing temperature is 30-40°C, the time is 10-15 minutes, and then dehydrated and dried;

[0067] 2) Fin...

Abstract

The inventions discloses a method for chemical modification, pigment dyeing and overflow sand wash of a fiber and application thereof to garment dyeing. The method comprises the following steps of: carrying out an anode chemical modification reaction on a cellulosic fiber of a fiber product by using a cation denaturing agent under the non-alkali condition of a fiber product; and then carrying out pigment dyeing and overflow sand wash treatment to enable the fiber product to form the traditional stone washing old-coped effect. Compared with the traditional processing technology, the invention has the advantages that: the hand feeling and the firmness of the products can be improved by modifying the fiber for pigment dyeing, and meanwhile, the technology can be simplified, the process can be shortened, and the consumption and the pollution can be reduced. The invention solves the quality problems on the hand feeling, the firmness, the color reproducibility and the like in traditional garment stone milling treatment.

Description

technical field [0001] The invention relates to a fibrosis paint dyeing technology and the application of the technology in garment dyeing. Background technique [0002] The production of traditional washed casual fabrics with distressed effects is mostly processed by paint dyeing and garment stone washing. The product has problems of hand feeling and washing fastness. Secondly, there are problems of color adaptation range and color reproducibility, which seriously affect the product processing range and wearing performance. Due to the long process route of the product in the production process, it is easy to cause product quality fluctuations, consume a lot of water and energy, and generate a lot of production wastewater to pollute the environment. Contents of the invention [0003] The purpose of the present invention is to provide a method of chemical denaturation of fibers, paint dyeing and overflow sand washing and the application of this method in garment dyeing, an...
