Embodiment 1

[0127] Including low-shrinkage processing: singeing, desizing, scouring, bleaching and dyeing of high-elastic white gray fabric, low-shrinkage treatment, and twice pre-shrinkage treatment.

[0128] The low-shrinkage treatment process for high-elastic fabrics is as follows: soak and dry the fabric twice, with a rolling pressure of 0.3Mpa, a water temperature of 50°C, and a vehicle speed of 50m / min; Treat at 65°C for 10 minutes; 5 times of low-tension oscillating spray washing water treatment, first use hot water spraying and oscillating washing water with a temperature of 80 ℃, and the last water tank is spraying and oscillating washing water at room temperature, the oscillating roller speed is 41r / min, The tension of the gravity induction roller is 12KG; the rolling process is carried out, and the pressure of the rolling machine is 0.3Mpa; after rolling, it is dried on the sizing machine, the drying temperature is 170°C, and the drying time is 60 seconds.

[0129] Common proce...

Embodiment 2

[0134] Singeing, desizing, low-shrinkage, and twice pre-shrinkage are performed on the high-elastic yarn-dyed gray fabric.

[0135]The low-shrinkage treatment process for high-elastic fabrics is as follows: soak and dry the fabric once, with a rolling pressure of 0.3Mpa, a water temperature of 70°C, and a vehicle speed of 70m / min; The temperature is 70°C for 30 minutes; 3 times of low-tension oscillating spray washing water treatment, first using hot water spraying and oscillating washing water at 75 ℃, and the last water tank is spraying and oscillating washing water at room temperature, the oscillating roller speed is 42r / min, the tension of the gravity induction roller is 13KG; after washing with water, it is rolled and dried, and the rolling pressure is 0.3Mpa; after rolling, it is dried on the setting machine, the drying temperature is 170 ° C, and the drying time is 80 seconds.

[0136] Common processing is singeing, desizing, tentering, and twice pre-shrinking.

[013...

Embodiment 3

[0141] The high-elastic denim gray fabric is subjected to singeing treatment, low-shrinkage treatment, and twice pre-shrinkage treatment.

[0142] The low-shrinkage treatment process for high-elastic fabrics is as follows: the high-elastic fabrics are soaked twice and then rolled dry, at 65°C, with a speed of 60m / min, and a rolling pressure of 0.3Mpa; It is normal temperature, and the treatment time is 10 minutes; 2 times of rolling and drying of high-elastic fabrics; Use hot water at 75°C to spray and oscillate the washing water. The last water tank is oscillating and washing at room temperature. The rotating speed of the oscillating roller is 41r / min, and the tension of the gravity induction roller is 13KG; It is 0.3Mpa; it is dried in a setting machine, the drying temperature is 170°C, and the drying time is 80 seconds.

[0143] Common processing is singeing, desizing, tentering, and twice pre-shrinking.

Abstract

The invention discloses a low-shrinkage treatment method and device and an after-treatment method. The low-shrinkage treatment method comprises the following steps that soaking and complete squeezingare conducted at least one time; wet boiling spraying loose-type piling is conducted at least one time; low-tension spraying vibration washing treatment is conducted at least three times; complete squeezing and drying are conducted. According to the low-shrinkage treatment method for a highly-elastic fabric, the highly-elastic fabric can be produced continuously, the production efficiency is improved, using of manpower, water and equipment is reduced, and production cost of production process links and the like is reduced. After treatment by the low-shrinkage treatment method, the effects of high-elasticity and low-shrinkage rate of the highly-elastic fabric can be achieved, and therefore the difficultly in highly-elastic type garment production and garment washing is reduced.

Description

technical field [0001] The invention relates to the technical field of cloth finishing, and mainly relates to a low-shrinkage processing method, a finishing method and a device. Background technique [0002] At present, domestic and foreign high-elastic fabrics will undergo multiple pre-shrinking treatments such as primary pre-shrinking and secondary pre-shrinking during finishing processing. The purpose is to narrow the door width and reduce the weft shrinkage rate. After the above finishing, The weft shrinkage of high-elastic fabrics still reaches -15% to -20%. High shrinkage has the following adverse effects on the garment manufacturing or garment washing of high-elastic fabrics: 1. The high-elastic fabrics cannot be curled during the cutting process. Sewing; 2. The high-elastic fabric shrinks sharply after washing at the seam joints of the garment, causing de-bombing; 3. The size of the garment will become unstable when the high-elastic fabric is washed. Patent No. CN 1...
