Embodiment 1

[0030] A novel dyeing and finishing process for PTT shape-memory fabrics, comprising the following steps:

[0031] ① Pretreatment of the gray cloth, that is, flat washing. The flat washing process includes four flat washing tanks, and the water temperature in each flat washing tank is different. The water temperature of the first flat washing tank to the fourth flat washing tank is set from low to high at 50°C, 85°C, 95°C and 98°C, add detergent, degreasing agent, and oxidation desizing agent to the second flat washing tank, and the dosage per liter of water is 3 grams, 4 grams, and 2.5 grams respectively. The outlet of the trough is equipped with a spray device to wash away the dirt and slurry on the cloth surface.

[0032] ②Manual unwinding.

[0033] ③ Nailing thread: Fold the front of the cloth in half in the meridian direction, and nail thread ends along the edge of the cloth, usually every 50 cm.

[0034] ④ Refining, the temperature is controlled at 70°C for 20 minutes...

Abstract

The invention discloses a novel dyeing and finishing process for PTT shape memory fabric, belongs to the technical field of textile fabric production, and comprises the following steps: 1, evenly washing gray cloth; 2, manually unwinding; 3, stitching threads, namely stitching thread ends along the edge of the cloth; 4, refining at a temperature of between 70 and 80 DEG C for 15 to 20 minutes; 5, pre-setting at a temperature of between 120 and 130 DEG C and a speed of between 40 and 50 m / min; 6, dyeing, wherein the starting dyeing temperature of disperse dye is between 26 and 32 DEG C, the rate of temperature rise is between 0.5 and 1 DEG / min and the temperature of between 70 and 80 DEG C is kept for 10 minutes in the starting dyeing process; and then the temperature is raised at the same rate to be between 100 and 110 DEG C for heat preservation for 30 to 60 minutes, a sample is dyed, the temperature is reduced to 70 DEG C at the same rate and water is discharged; 7, performing reduction washing in water with a temperature between 60 and 80 DEG C for 15 and 20 minutes; and 8, sizing a finished product at a temperature of between 110 and 125 DEG C for 12 to 18 seconds. The novel dyeing and finishing process solves the problems of the easy occurrence of dyeing defects, color traces, scratches, chicken paw prints, and the like in the prior dyeing and finishing process, and endows the memory fabric with good memory performance to improve the product quality.

Description

technical field [0001] The invention discloses a novel dyeing and finishing process of a PTT shape memory fabric with PTT as the main component, belonging to the technical field of textile fabric production. Background technique [0002] The main features of PTT (polytrimethylene terephthalate) shape-memory fabrics are: easy-to-care garments, and the fabric surface can be restored to its original flat state after being folded and creped, which belongs to the combination of force and body temperature. Stimulus-induced shape memory products; good plasticity, convenient for clothing styling, the fabric can be folded or pinched by hand, and the fabric can be made into the desired shape. Its characteristics are similar to the shape-memory metal fiber blended fabric that came out a few years ago. Due to the limitations of raw materials, processing technology, etc., metal fiber shape memory fabrics are not easy to promote and popularize, but today's PTT polymer shape memory fabrics...
