Problems solved by technology

At present, there are the following four solutions to the twisting problem: 1) Using S and Z twisted yarns as gaps to weave alternately, but it will affect the effect of the cloth surface; 2) Using the method of reverse mercerizing, which has a significant effect on cotton fabrics , but little improvement for polyester-cotton fabrics; 3) Reverse resin finishing is used, which increases production costs, and there is a problem of formaldehyde release in fabrics after finishing, and at the same time, it has adverse effects on physical and mechanical properties such as strength and hand feeling of fabrics; 4) Clothing Pre-stretching treatment is performed according to the degree of twist of the fabric before cutting. The disadvantage is that the inclination is difficult to control accurately, and it is not suitable for fabrics with weft stripes.

Embodiment 1

[0011] Material: 120*9045(55%T45%C)*45(55%T45%C), finished fabric width 57 / 58", right slanted 2 / 2;

[0012] The steps include singeing → desizing → mercerizing → shaping → preshrinking → code cloth, among which singeing: one positive and one negative gas singeing, the speed of the machine is 120m / min, and the oil volume is 12kg / h;

[0013] In the desizing process, amylase is used for desizing, the vehicle speed is 80m / min, stacked at 55°C for 35min, washed with water for 2 compartments at 85°C and 3 compartments at 55°C.

[0014] In the mercerizing process, the alkali concentration is 370g / L, and the fabric is normally dropped.

[0015] Shaping process, 120 ℃, polyurethane elastic finishing agent 50g / L, speed of 40m / min, normal falling cloth.

Embodiment 2

[0017] Material: 120*9045(55%T45%C)*45(55%T45%C), finished fabric width 57 / 58", right slanted 2 / 2;

[0018] The steps include singeing → desizing → mercerizing → shaping → preshrinking → code cloth, among which singeing: one positive and one negative gas singeing, the speed of the machine is 120m / min, and the oil volume is 12kg / h;

[0019] In the desizing process, amylase is used for desizing, the vehicle speed is 80m / min, stacked at 55°C for 35min, washed with water for 2 compartments at 85°C and 3 compartments at 55°C.

[0020] In the mercerizing process, the alkali concentration of 370g / L is used, and the speed of the clip chain is adjusted to ensure that the stroke of one side of the fabric is greater than that of the other side. When the fabric is loaded with alkali, it is skewed by 25cm, and the warp and weft are guaranteed to be perpendicular to each other when falling;

Embodiment 3

[0023] Material: 120*9045(55%T45%C)*45(55%T45%C), finished fabric width 57 / 58", right slanted 2 / 2;

[0024] The steps include: singeing → desizing → mercerizing → primary setting → secondary setting → preshrinking → code cloth, among which singeing: one positive and one negative gas singeing, the speed of the machine is 120m / min, and the oil volume is 12kg / h;

[0025] In the desizing process, amylase is used for desizing, the vehicle speed is 80m / min, stacked at 55°C for 35min, washed with water for 2 compartments at 85°C and 3 compartments at 55°C.

[0026] In the mercerizing process, use an alkali concentration of 370g / L, adjust the chain speed of the cloth clips, reverse the skew by 25cm when the fabric is alkali-laden, and adjust the weft aligner after washing to ensure that the fabric falls normally;

[0027] Once setting, the temperature is 170°C, the water is squeezed, the speed of the vehicle is 30m / min, and the weft adjuster is adjusted to ensure that the fabric is sk...

Abstract

The invention discloses a dyeing and finishing processing method for improving the distortion of a polyester cotton natural elastic twill fabric. The method comprises the steps of singeing, desizing, mercerizing, sizing for the first time, sizing for the second time, preshrinking and plaiting, wherein alkali with the concentration of 350-400g / L is adopted in the mercerizing working procedure, the speed of a cloth clamping chain is adjusted, the stroke of one side of the fabric is larger than that of the other side of the fabric, and the anti-oblique degree of the fabric is 15-25% when the alkali is carried by the fabric, and a weft straightener is adjusted after the fabric is washed and the alkali of the fabric is removed, so that the normal doffing of the fabric is guaranteed; the temperature of 160-175 DEG C is adopted in the sizing for the first time, squeezing is carried out, and the weft straightener is adjusted to enable the fabric to be pulled reversely in an inclined way by 15-25% for 30-45 seconds; during the sizing for the second time, the temperature is controlled to be 100-130 DEG C, a polyurethane elastic finishing agent is padded, and normal doffing is realized. The distortion of the polyester cotton natural elastic twill fabric produced by adopting the dyeing and finishing processing method reaches the standard of textile industry and can meet the requirements of customers.

Description

technical field [0001] The invention relates to a dyeing and finishing method for improving the distortion of polyester-cotton natural elastic twill fabric, and belongs to the technical field of dyeing and finishing of synthetic fibers in the printing and dyeing industry. Background technique [0002] Polyester-cotton natural elastic twill fabric has the characteristics of crisp and wrinkle-free, easy to wash and dry, stable shape, soft hand feeling, and comfortable to wear. It is the first choice for making shirt fabrics and is deeply loved by consumers. The twill weave itself has less interweaving points than the plain weave. During the washing process, due to the swelling of the fibers and the relaxation of internal stress, it is easy to cause distortion. In addition, in order to obtain better natural elasticity, strong twisted yarn is used in the weft direction, which intensifies the twist of the fabric. After conventional finishing, the distortion of this kind of fabri...
