Description

A kind of faux-old processing method of colored fabric

technical field

The invention relates to a method for processing fabrics in the textile industry, in particular to an imitation processing method for colored fabrics.

Background technique

Distressed processing can make the surface of the fabric or garment produce a worn-out feeling, catering to people's psychology of pursuing fashion. At present, the methods used for the imitation processing of fabrics or garments mainly include stone washing, rinsing and vulcanization.

Stone washing refers to putting clothes and a certain amount of pumice, a small amount of stripping agent (such as sodium hypochlorite, potassium permanganate, etc.) and detergent into the drum washing machine for grinding, using the friction between the pumice and the clothes Make the dyes on the clothes fall off, and produce whitening on the edges and seams of the clothes, so as to achieve the effect of "worn sense"; rinsing is to use the oxidation of hydrogen peroxide or sodium hypochlorite to destroy the structure of the dyes on the clothes, so as to achieve The effect of fading and whitening; the above stone washing and rinsing are mainly for the distressed treatment of garments, and the distressed effect is not uniform; and vulcanization is mainly for the distressed treatment of fabrics, but the vulcanization process pollutes the environment and can consumes more.

Contents of the invention

The technical problem to be solved by the present invention is to provide an imitation processing method for colored fabrics with uniform effect of imitation treatment, low energy consumption and environmental protection.

The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a kind of imitation processing method for colored fabrics, which is to add a cationic modification process to the yarn before the traditional yarn dyeing and weaving process, so that the entire processing process The steps are: yarn preparation→yarn cationic modification→yarn dyeing and weaving processing→sizing→preshrinking→washing→finished product.

The yarn cationic modification process is as follows: add 30-100 g/L modifier in the size tank of the single yarn sizing machine, then let the yarn undergo cationic modification through the single yarn sizing machine, and put the modified The yarn is wound onto the paper tube to form a bobbin yarn, the loose yarn density of the bobbin is controlled to be 0.30-0.40g/cm ³ , and the single yarn weight is 0.3-0.8Kg/bobbin.

Described yarn cationic modification process is:

(1), shake the yarn on the skein shaker, control the weight of the yarn to be 300-500g/turn, and the thickness of the yarn is uniform;

(2) Add 0.5-2g/L of refining agent into the skein jet dyeing vat, put the shaken yarn into the skein jet dyeing vat for slight refining, and heat-preserve at 80-100°C for 5-30 minutes;

(3), washing the refined yarn twice;

(4), carry out cationic modification to yarn in hank yarn dyeing machine, wherein the consumption of adding modifier is 10～80g/L, and the weight bath ratio of control yarn and modifier solution is 1: 5～ 20. Insulate at a temperature of 40-90°C for 5-30 minutes.

The yarn cationic modification process is as follows: first loosen the yarn on the winder, control the loose yarn density to 0.30-0.40g/cm ³ , and the yarn weight to 0.3-0.8Kg/bobbin, and then Add 10-80g/L modifier into the dyeing vat, put the loose yarn bobbin into the dyeing vat for cationic modification, and heat-preserve at 60°C for 10-60 minutes.

The yarn cationic modification process is as follows: first warp the yarn on the warping machine, then add 30-100 g/L modifier in the sizing tank of the sizing machine, and warp the warped yarn Put it into the sizing machine to carry out cationic modification according to the traditional warp sizing process.

The specific process steps of the yarn dyeing and weaving process are: dyeing→drying→winding→sizing→weaving→singing→desizing→mercerizing.

Add a water washing process for the yarn between the cationic modification of the yarn and the dyeing process. The specific process is: put the yarn in the dyeing vat and enter the hot water, and keep it warm at a temperature of 40-80°C for 5-50°C. 20min, then drain, this process can promote the dyeing of subsequent yarn dyeing process to be more uniform.

The specific process steps of the yarn dyeing and weaving process are: drying → winding → sizing → weaving → singeing → desizing → mercerizing → dyeing.

The dyeing process is as follows: put the yarn or cloth into the dyeing vat and add water, then add dye into the dyeing vat, raise the temperature to 80°C at a heating rate of 1-3°C/min, and keep it warm for 5-30min.

In the described dyeing process, before adding dyestuff to the dyeing vat, 2-10 g/L of low salt is added to the dyeing vat earlier. Compared with the traditional dyeing process, the above dyeing process has no salt and no alkali (or no alkali) in the dyeing process. low salt), thereby saving energy, reducing costs, and reducing the burden of pollution and sewage treatment.

The modifier used in the present invention adopts the Quat188 ionic reagent produced by Dow Chemical China Co., Ltd., which is a cationic monomer containing reactive functional groups, which can be combined with anions to improve natural and synthetic polymers. Produces quaternary ammonium compounds, which are primarily used in the chemical processing, personal care products/cosmetics, pulp and paper, textiles and water management industries.

The refining agent adopts Qililong XC-J concentration agent produced by BASF Chemical Co., Ltd., which is a colorless to light yellow clear liquid, which is a mixture of nonionic surfactants containing alkoxylated long-chain fatty alcohols. It does not contain APEO and phosphoric acid components. At room temperature, it can withstand 30g/L NAOH 100%. It has high stability and will not cause stratification in high-efficiency circulation equipment. It is a kind of emulsification and washing High-performance low-foaming wetting agent and detergent, which can effectively remove impurities and oil stains in synthetic fibers and their blends, and improve the safety and reproducibility of subsequent processing. It is suitable for cotton, chemical fibers and their blends before dyeing. Processing.

The dye adopts DyStar Remazol dye produced by DyStar Dyestuff Co., Ltd., which is a reactive dye that can be chemically bonded with cellulose fibers.

Compared with the prior art, the present invention has the advantage of increasing the cationic modification of the yarn before the traditional yarn dyeing and weaving processing, so that the surface layer of the yarn is evenly colored, while the inner layer of the yarn maintains the original white core , forming an obvious skin-core effect, so that the processed fabric has uniform ring dyeing, and the effect of distressed treatment is uniform; and through the combined application of cationic modifiers and reactive dyes, the dyed fabric has reached the level of sulfur dyes or indigo dyes. The effect can only be achieved, which greatly reduces energy consumption, reduces environmental pollution, ensures dyeing stability and production efficiency, and improves product quality.
