Description

Method of Stonewashing Soft Shaggy Fabrics

technical field

The present invention relates to woolen textile products, and in particular to a method for stonewashing soft coarse woolen fabrics.

Background technique

With the improvement of material living standards, consumers' requirements for the quality and wearing performance of woolen fabric clothing products are no longer limited to keeping warm. Consumers not only need comfort, but also pursue diversified, personalized and distinctive products. For example, retro nostalgic style jeans are specially made to be faded or even worn out at the hips and knees. This method is usually treated with special equipment such as fading agents and sand washing. For clothes made of woolen fabric, because the strength is much lower than that of jeans, especially the shrinkage of woolen fabric is too large, it is impossible to use the method similar to making jeans to carry out old-fashioned treatment on the clothes made of woolen fabric.

Contents of the invention

The object of the present invention is to provide a method for stone-washing soft coarse woolen fabrics with whitened surface, faded color, fresh and natural fluff, elastic fabric, soft handle, large color contrast between front and back, and retro nostalgic feeling.

In order to meet the above requirements, the method of stone-washing soft coarse woolen fabrics: its features include in turn the mercerizing treatment of fibers, spinning yarns, textile fabrics, curing and anti-shrinkage treatment, garments, dyeing, stone-washing clothes, drying finishing, The specific processing technology is:

(1) Mercerizing treatment: Mercerizing the fibers that need to be made into old wool textile fabrics, and peeling off the scales on the surface of the fibers;

(2) Spinning yarns and weaving fabrics: using fibers stripped of surface scales to spin yarns and weaving yarns into fabrics according to the woolen method;

(3) Curing and anti-shrinkage treatment of the fabric, treatment process:

Ratio of treatment liquid → two dips and two rollings of the fabric in the treatment liquid at room temperature, the excess rate is 70% → heating to 120°C, keeping warm for 6 minutes Pre-baking → heating up to 140°C, holding for 4 minutes and baking → lowering to room temperature;

Among them, the proportion of treatment liquid is based on the amount per liter of water: water-soluble polyurethane wool anti-shrinkage agent, the amount is 100-150g/L, the amount of _NaHCO3 is 3-6g/L, and the amount of fatty alcohol polyoxyethylene ether penetrating agent is 1.5g/L;

(4) Ready-made garments: fabrics that have been treated with anti-shrinkage are used to make garments according to requirements;

(5) Dyeing: Use neutral dyes, 80% concentration of acetic acid 0.8-1.2%, sodium sulfate 4.5-5.5%, bath ratio 1:10-20 for dyeing, so that the neutral dyes can be colored on the surface as much as possible, and the dyes will not penetrate deeply. The inside of the yarn of the fabric; the pH value is 4.5-5 to promote dyeing, the rapid temperature increase is 2.5°C/min, the initial dyeing temperature is 55°C, the holding temperature is 85°C, and the holding time is 8-12 minutes. The soaping color fastness of the fabric is controlled at Within level 2.5;

(6) Stone-washed clothing:

Selection of stone washing medium: choose volcanic stone with a size of 30-50mm, volcanic stone index: specific gravity 0.3-0.4g/cm ³ , water absorption rate 50%-60%, pore volume accounting for more than 50% of volcanic stone volume;

Soaking of volcanic stone: Soak the dry volcanic stone in the aqueous solution of protease and detergent for 1-2 hours, and stir to make the volcanic stone fully absorb the aqueous solution. The amount of protease is 0.4-0.6 grams per kilogram of fabric, and the amount of detergent It is 0.25-0.35 grams per kilogram of fabric, and the weight ratio of water and protease is 4.5-5.5: 1;

Stone washing is carried out in a large horizontal industrial washing machine, the specific process is as follows:

Garment soaking: Soak the garment in warm water, water-to-bath ratio 1:10, water temperature 45°C, soak for 8-12 minutes → add the volcanic stone soaked in the solution: the amount of volcanic stone is 40-60 grams per kilogram of fabric, → turn on the washing machine and start Stir and stone wash, and heat up, heating rate 1°C/min, to 62-67°C, stone wash for 12-16 minutes → naturally cool down to 55°C, stone wash for 25-35 minutes → heat up to 72-77°C, stone wash 8 -12 minutes→take out the volcanic stone→clean with water once, cool down to 35-40°C, bath ratio 1:25, wash for 8-12 minutes→add water for second wash: cool down to 30-35°C, bath ratio 1:25 , wash for 12-16 minutes → dehydrate out of the tank;

(7) Drying and finishing: dry and iron the stone-washed garments according to conventional methods to form finished products.

Described protease is papain.

The fiber used in the coarse woolen fabric is wool.

With this method of stone-washing soft coarse woolen fabrics, due to the mercerizing treatment of the fibers before spinning, the scales on the surface of the fibers are peeled off, so that the surface of the fibers becomes smooth and oval. When the fibers rub against each other, the fibers that lose their scales The shrinkage will be greatly reduced, thereby improving the anti-shrinkage performance of the fabric. In addition, the fabric is treated with M-501 wool anti-shrinkage agent, which strengthens the stability between fibers, solidifies and shapes the fabric, and keeps the yarn structure relatively stable in stone-washing softness for fabrics with lower tightness, without slipping, Rotate, so that only the surface is ground during the stone washing process, and the efficiency of stone washing can be increased. In the old way, the solution is prepared first, and then the volcanic stone is soaked in the prepared solution, so that the volcanic stone is soaked in the solution, and the volcanic stone soaked in protease and detergent is used for stone washing, so that it is slowly released in the stone washing protease and detergent. Protease has the function of decomposing protein, and at the same time control the temperature to exert the effect of protease, so that the fluff on the surface of the fabric is scarce. In the process of stone washing, volcanic stones with a certain roughness and appropriate weight are used to impact and knead the surface of the garment to make the surface of the garment white, faded, fresh and natural with less fluff, the fabric is elastic, softer to the touch, and the color is positive and negative. There is a large contrast and a sense of retro nostalgia. This method successfully controls the serious disadvantages of sand washing and shrinkage of woolen fabrics through the two anti-shrinkage treatments in the early stage and the selection of volcanic stone washing soaked in protease and detergent, and effectively prevents the damage to the fabric during the aging process. Excessive damage prolongs the life of the garment.
