Preparation method of terylene gigging fabric

Abstract

The invention discloses a preparation method of a terylene gigging fabric, and belongs to the technical field of terylene fabrics, the preparation method of the terylene gigging fabric adopts a preparation method of first sanding and then flocking, the surface performance of the fabric is improved by first sanding, fluff is easy to adsorb, and the fluff is easy to adsorb by adopting a process of first sanding and then flocking. Easily-broken long fluff can be removed, the surface smoothness of the fabric can be improved, the color fastness can be improved to a great extent, the defects that a cloth cover wrinkles and fluff does not come out at the wrinkles are avoided, the fluff density and the fluff uniformity of the cloth cover are improved, the fluff is full, upright and uniform, the suede is soft and smooth, the soft touch feeling of the surface of the fabric is improved, and the stiff and smooth degree is similar to that of genuine leather; and the wear-resisting property is good. In the prior art, a one-step flocking process is adopted and then fluff is treated, but flocking is performed firstly and sanding is performed in a direction opposite to the movement direction of base cloth, so that the fabric has the defect of easy hemming, the process flow is difficult to carry out, and the plump and upright particle fluff effect cannot be obtained.

Description

Technical Field

[0001] The invention belongs to the technical field of polyester fabrics, and particularly relates to a method for preparing polyester fleece fabrics. Background Art

[0002] Polyester fleece fabric products have gorgeous appearance, concave and convex three-dimensional flower shapes and rich and delicate feel, and are deeply loved by consumers. For example, CN201910495949.6 discloses a high-peeling three-proof composite sofa fabric with polyester fleece fabric as the bottom substrate. The existing process adopts a one-step flocking process and then processes the fluff, but the flocking is first performed, the movement direction of the base cloth is reversed, and then the fluff is sanded. The fabric has the defect of easy curling, but the flocking effect is greatly reduced, the feel is hard, and the three-dimensional sense is poor, such as the hair does not stand up, the hair is inverted, and the cloth feels too soft and not crisp. Those skilled in the art are in urgent need of developing a method for preparing polyester fleece fabric to meet existing usage requirements and market demand. Summary of the invention

[0003] The purpose of the present invention is to provide a method for preparing a polyester fleece fabric to solve the above technical problems.

[0004] A method for preparing a polyester fleece fabric comprises the following steps: (1) Prepare polyester grey fabric: Open the width of the polyester grey fabric, wash and degrease it with water, and use a degreasing agent of 0.5 to 1 g / L; (2) Use a sanding machine to sand the grey fabric under a water spray state; (3) Wash the sanded grey fabric with water to remove dirt on the grey fabric; (4) Use a dehydrator to dehydrate the grey fabric to remove excess water in the grey fabric; (5) Dry and shape: The dehydrated grey fabric needs to be dried and shaped at a temperature of 195 to 200°C and a time of 20 to 25 seconds to obtain a sanded polyester grey fabric; (6) Apply an adhesive to the surface of the sanded polyester grey fabric, then flock it, bake it, brush it, and then finish it to obtain a polyester raised fabric.

[0005] Furthermore, the applied voltage is 40-60 kV, the pole distance is 10-15 cm, and the flocking time is 8-10 s.

[0006] Furthermore, the moisture content of the fluff is 2-3%, and the soaring speed is 8-10s / 2g.

[0007] Furthermore, the diameter of the sanding roller of the sanding machine is 215 mm, the rotation speed is 500 rpm, and the number of sanding rollers is 6; the diameter of the 5 brush rollers of the sanding machine is 280 mm, the rotation speed is 800 rpm, and the vehicle speed is 20 m / min.

[0008] Furthermore, the post-finishing is a water finishing solution with a bath ratio of 1:25-30, a softener containing 2%-2.5% by mass, a pH of 7-7.2, and a temperature of 30-35°C, which is treated for 5-10 minutes and then washed twice and dried.

[0009] Furthermore, the brushing parameters are a cloth feeding speed of 25 to 40 m / min, a cylinder speed of 80 to 110 rpm, a tension setting of 1.00, 1.01, 1.03, 1.04, and a brushing force of 15 to 20 N.

[0010] The present invention has the following beneficial effects: The preparation method of polyester pile fabric disclosed in the present invention adopts a preparation method of first sanding and then flocking. The first sanding improves the surface performance of the fabric, and the pile is easy to adsorb. The first sanding and then flocking process can remove the long pile that is easy to break, improve the smoothness of the fabric surface, and can greatly improve the color fastness, avoid the defects of wrinkling of the cloth surface and the lack of pile at the wrinkled part, improve the cloth surface pile density and pile uniformity, the pile is plump, upright and uniform, the pile surface is soft and smooth, the soft touch of the fabric surface is improved, the stiffness is similar to that of genuine leather, and has good wear resistance. The surface pile is dense and upright, feels thick, plump, soft, and elastic. The pile is fluffy and dense but not easy to shed. The existing process adopts a one-step flocking process and then processes the pile, but flocking is first performed, and then sanding is performed in the opposite direction of the base cloth movement. The fabric has the defect of easy curling, the process flow is difficult to carry out, and the plump and upright granular pile effect cannot be obtained. DETAILED DESCRIPTION
