Problems solved by technology

Tight mercerizing is not conducive to the penetration of lye under the condition of large warp tension of the ventilation roller, and is prone to surface mercerizing, which affects the final mercerizing effect, and the fluffy degree of the fabric after processing is reduced

Embodiment 1

[0032] A low-alkali-concentration loose-stack mercerizing process for processing cotton fabrics, comprising the following steps in turn:

[0033] First, the fabric is put into the dry cloth in open width, and the fabric enters the first rolling groove for one padding. The padding solution contains caustic soda 170g / L. The one padding method is two dipping and two rolling. The pressure of the first padding car is 0.26Mpa, and the second padding The pressure of the second rolling car is 0.18Mpa, the excess rate is 70%, and the interval between the first padding and the second padding is 9s. After completing one padding, the fabric enters the J-shaped box for negative pressure stacking. The negative pressure stacking time of the J-shaped box is 5 minutes, the stacking temperature is 25°C, and the pressure is -0.2MPa. The negative pressure environment is provided by a vacuum pump. During the negative pressure stacking period of the J-shaped box, the fabric will fully swell and shr...

[0035] A low-alkali-concentration loose-stack mercerizing process for processing cotton fabrics, comprising the following steps in turn:

[0036]First, the fabric is put into the dry cloth in open width, and the fabric enters the first rolling groove for one padding. The padding solution contains caustic soda 180g / L. The one padding method is two dipping and two rolling. The pressure of the first padding car is 0.33Mpa, and the second padding The pressure of the second rolling car is 0.23Mpa, the excess rate is 75%, and the interval between the first padding and the second padding is 9s. After completing one padding, the fabric enters the J-shaped box for negative pressure stacking. The negative pressure stacking time of the J-shaped box is 7 minutes, the stacking temperature is 30°C, and the pressure is -0.3MPa. The negative pressure environment is provided by a vacuum pump. During the negative pressure stacking period of the J-shaped box, the fabric will fully swell and shri...

Embodiment 3

[0038] A low-alkali-concentration loose-stack mercerizing process is used to process polyester fabrics, which includes the following steps in turn:

[0039] First, the fabric is put into the dry cloth in open width, and the fabric enters the first rolling groove for one padding. The padding solution contains caustic soda 175g / L. The one padding method is two dipping and two rolling. The pressure of the first padding machine is 0.30Mpa, and the second padding The pressure of the second rolling car is 0.20Mpa, the excess rate is 72%, and the interval between the first padding and the second padding is 9s. After completing one padding, the fabric enters the J-shaped box for negative pressure stacking. The negative pressure stacking time of the J-shaped box is 6 minutes, the stacking temperature is 26°C, and the pressure is -0.25MPa. The negative pressure environment is provided by a vacuum pump. During the negative pressure stacking period of the J-shaped box, the fabric will ful...

Abstract

The invention discloses a slack mercerization technology with low alkali concentration, and relates to the technical field of spinning. The slack mercerization technology with the low alkali concentration comprises processes as follows: open-width feeding, primary padding, negative-pressure piling in a J type box, secondary padding, tension roll drafting, expanding for alkali removal, freezing foralkali removal, flat washing and drying. The technology further comprises step that the negative-pressure piling in the J type box is performed for 5-7 min at the piling temperature of 25-30 DEG C and pressure of (-0.2)-(-0.3) MPa under the condition of caustic soda concentration being 170-180 g/L. Prepared textile artware has good quality and low wrinkle rate, the mercerization effect is improved, meanwhile, the consumption of caustic soda is reduced, and the technology has positive significance in aspects of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a loose pile mercerizing process with low alkali concentration. Background technique [0002] Mercerized refers to the silky luster on the surface of certain cotton fabrics after processing. Conventional tight mercerizing refers to the mercerizing process that the fabric is treated with concentrated alkali (240-260g / L) under tension for a short time, and then stretched for ventilation, then rolled with lye, expanded washing, steam washing, and water washing. Polyester will not expand and shrink in concentrated alkali, and its morphological structure, especially the supramolecular structure, will not change. Tight mercerizing is not conducive to the penetration of lye under the condition of high warp tension of the ventilation roller, and is prone to surface mercerizing, which affects the final mercerizing effect, and the fluffy degree of the fabric after processing is reduced. ...
