Embodiment 1

[0024] The setting machine adopts ordinary heat setting machine, a car of 40 meters, and an oven of about 20 meters. First dye the Parster fiber fabric purple (dye: cationic red X-GRL, cationic blue X-BL), wash and dry the dyed fabric, sew the cloth head and prepare to enter the setting machine. The water tank of the setting machine should be filled with water. Carry out wet treatment to the fabric, adjust the pressure of the roller, let the fabric carry the liquid evenly, and the liquid carrying rate reaches about 70%. Set the temperature of the sizing machine to 95°C (it is necessary to let the sizing machine rise from a lower temperature to the set temperature, not during the cooling process), adjust the speed to 15 yards per minute, and set the door width to the natural width of the fabric. Once everything is set, heat styling begins.

[0025] The fabric heat-set by the above method can not only maintain the supersoft performance of the Parster fiber fabric, but also meet...

Embodiment 2

[0027] The setting machine adopts ordinary heat setting machine, a car of 45 meters, and an oven of about 25 meters. First dye the Parster fiber fabric orange red (dye: cationic red X-GRL, cationic yellow X-GL), wash and dry the dyed fabric, sew the cloth head and prepare to enter the setting machine. The water tank of the setting machine should be filled with water. Wet treatment is carried out on the fabric first, and the pressure of the roll is adjusted to make the fabric evenly loaded with liquid, and the liquid-carrying rate reaches about 50%. Set the temperature of the sizing machine to 90°C (it is necessary to let the sizing machine rise from a lower temperature to the set temperature, not during the cooling process), adjust the speed to 19 yards per minute, and set the door width to the natural width of the fabric. Once everything is set, heat styling begins.

Embodiment 3

[0030] The setting machine adopts ordinary heat setting machine, a car of 50 meters, and an oven of about 30 meters. First dye the Parster fiber fabric with deep black (dye: cationic black X-O, cationic black X-RL), wash and dry the dyed fabric, sew the cloth head and prepare to enter the setting machine. The fabric is wet-treated, and the pressure of the roll is adjusted to make the fabric evenly loaded with liquid, and the liquid-carrying rate reaches about 80%. Set the temperature of the sizing machine to 100°C (it is necessary to let the sizing machine rise from a lower temperature to the set temperature, not during the cooling process), adjust the speed to 17 yards per minute, and set the door width to the natural width of the fabric. Once everything is set, heat styling begins.

[0031] The fabric heat-set by the above method can not only maintain the supersoft performance of the Parster fiber fabric, but also meet certain requirements in terms of shrinkage fastness and...

Abstract

The invention relates to a humid heat setting method for a copolyester Parster fiber fabric, comprising the following steps: performing padding wet treatment on a dyed Parster fabric, ensuring uniform liquid on the fabric, and feeding the fabric into a setting machine in the mode of a natural door width to obtain the product in the invention, wherein the temperature is controlled between 90 and 120 DEG C, and the speed is 15-21 yards / min. By using the humid heat setting method of the invention, the properties of the Parster fiber subjected to afterfinish can be effectively improved, and in the method, the setting temperature is relatively low, the cost is saved, the energy consumption is reduced and the market prospect is good.

Description

technical field [0001] The invention belongs to the technical field of post-dyeing finishing of copolyester fiber fabrics, and in particular relates to a wet heat setting method of copolyester Paiste fiber fabrics. Background technique [0002] Due to the tight molecular structure, high crystallinity and high degree of orientation of conventional polyester fiber, it has high breaking strength and elastic modulus, moderate resilience, excellent heat setting, good heat resistance and light resistance. Moreover, polyester fiber fabrics are stable to weak acids and alkalis, corrosion-resistant, have good washability and wearability, and are resistant to organic solvents, soaps, detergents, bleaches, oxidants, etc., so polyester fibers have become the fastest growing fabrics. One of the fastest and highest yielding synthetic fibers. [0003] Traditional polyester fiber dyeing often needs to be carried out under high temperature and high pressure conditions to achieve a high dye ...
