Problems solved by technology

[0002] The pretreatment of cotton fabrics generally adopts the traditional process of high temperature and strong alkali. Not only the production conditions are harsh, but also a large amount of strong alkaline wastewater is discharged, which affects the ecological environment and human health. At the same time, the desizing and refining in the traditional process are divided into two steps, which wastes a lot of water. resources, do not meet the requirements of "green" and energy saving and emission reduction

preparation example Construction

[0008] The preparation method of the present invention is the following steps:

[0009] ①. Keep the fabric impregnated with the enzyme solution (enzyme temperature 60°C, stacking temperature 55°C, pH 7.0, NaCl 5g / L, JFC 1g / L, liquor ratio 1:25) and keep it stacked for 30-60 minutes , based on the fact that the enzyme has desized the size of the outer layer of the fabric to a better length, the biological enzyme for desizing can be selected from Bacillus subtilis amylase (α-amylase), HIC desizing enzyme, starch glucoamylase (β - amylase), pancreatic amylase, etc.;

[0010] ②. Soak fabrics that have been piled up for a period of time in enzyme solution (pectinase 4g / L-12g / L, penetrant JFC 2g / L, pH 7-10, temperature 50°C-60°C, time 60min-90min) , desizing and refining are carried out with the same bath, that is, the pectinase solution is added to the previous bath for desizing, in order to keep the bath ratio 1:25, the water content can be appropriately increased;

[0011] ③. B...

[0014] Ingredients: natural starch, PVA;

[0015] Preparation:

[0016] ①. Keep the fabric impregnated with the enzyme solution (enzyme temperature 60°C, stacking temperature 55°C, pH 7.0, NaCl 5g / L, JFC 1g / L, liquor ratio 1:25) and keep it stacked for 30-60 minutes , based on the fact that the enzyme has desized the size of the outer layer of the fabric to a better length, the biological enzyme for desizing can be selected from Bacillus subtilis amylase (α-amylase), HIC desizing enzyme, starch glucoamylase (β - amylase), pancreatic amylase, etc.;

[0017] ②. Soak fabrics that have been piled up for a period of time in enzyme solution (pectinase 4g / L-12g / L, penetrant JFC 2g / L, pH 7-10, temperature 50°C-60°C, time 60min-90min) , desizing and refining are carried out with the same bath, that is, the pectinase solution is added to the previous bath for desizing, in order to keep the bath ratio 1:25, the water content can be appropriately increased;

[0018] ③. Boil in water fo...

Embodiment 2

[0020] Ingredients: modified starch, PVA, and its preparation method is the same as that of Example 1.

[0021] In summary, the fabric of the present invention uses starch, PVA, etc. as raw materials, has fluffy and soft hand feeling, good comfort, short technological process, simple equipment, low energy consumption, less sewage, is convenient for large-scale production, and has good economical advantages. and social benefits.

Abstract

The invention relates to a method for fulfilling the fabric finishing and refining by use of biological enzyme in one time, which uses natural starch or converted starch or both starch and PVA as main sizing materials, wherein the fabric has good comfort, a puff and soft hand feeling, short technical process, simple device, little energy consumption, small polluted water and is suitable for mass production with good economy and social benefits.

Description

technical field [0001] The invention relates to a method for fabric desizing, in particular to a method for completing fabric desizing and refining at one time by using biological enzymes. Background technique [0002] The pretreatment of cotton fabrics generally adopts the traditional process of high temperature and strong alkali. Not only the production conditions are harsh, but also a large amount of strong alkaline wastewater is discharged, which affects the ecological environment and human health. At the same time, the desizing and refining in the traditional process are divided into two steps, which wastes a lot of water. Resources, do not meet the requirements of "green" and energy saving and emission reduction. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency, low-cost and environmentally friendly fabric desizing and refining treatment method, especially a method for fabric desizing and refining with biological...
