Problems solved by technology

[0008] In order to reduce the environmental pollution and fiber damage caused by the traditional pretreatment process of flax fabrics, people have begun to study the pretreatment of flax fabrics with biological enzymes in recent years, but due to the specificity of biological enzymes, lignin on flax fabrics is not Inadequately removed, still affects fabric dyeability, handle and style

Embodiment

[0058] Pretreatment of linen fabrics with combined enzymatic desizing, scouring and ozone bleaching of amylase and pectinase:

[0059] 1. Process flow:

[0060] The linen fabric is sequentially subjected to padding with compound enzyme solution of amylase and pectinase, steam stacking, water washing, liquid squeezing, ozone treatment, hot water washing, cold water washing and drying.

[0061] 2. Process description:

[0062] (1) Padding: pad the linen fabric in the compound enzyme solution, the temperature of the compound enzyme solution is 60-80°C, and the compound enzyme solution is composed of amylase, pectinase, nonionic surfactant, calcium chloride and water , among them, amylase 1.0g / L~5.5g / L, pectinase 1.5 g / L~3.5 g / L, nonionic surfactant 0.5 g / L~3.0 g / L, calcium chloride 0.1 g / L ~2.0 g / L.

[0063] In this example, 2.0 g / L of amylase, 3.5 g / L of pectinase, 1.5 g / L of nonionic surfactant, and 0.2 g / L of calcium chloride are preferred in this example.

[0064] The liq...

Abstract

The invention discloses a pretreatment technology for linen fabric, and belongs to the technical field of the dyeing and finishing pretreatment in the textile processing. The pretreatment technology comprises the following steps: firstly padding the linen fabric in complex enzyme solution containing amylase, pectinase and a non-ionic surfactant, and through steaming and piling, washing, squeezing,ozone-processing, hot-washing, and cold-washing, finally drying. The treated fabric has not residual impurities of starch slurry, hemicellulose, xylogen and pectin and the like, the loss of strengthis small, and the fabric has the fluffy, thick and soft effects. Compared with a traditional technology, because of the application of biological enzyme and a physical pretreatment technology, the pollutant discharge is remarkably reduced, the technology is beneficial to the environmental protection, and a water supply volume of washing the fabric can be reduced. Especially the ozone treatment hasthe remarkable energy-saving and water-saving effects because the treatment is performed in a room temperature and a damp state.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing pretreatment in textile processing, and in particular relates to the pretreatment technology of linen fabrics. Background technique [0002] Flax cellulose has the reputation of "fiber queen". As the main high-grade hemp spinning raw material, it has outstanding properties that other natural fibers cannot match, such as natural antibacterial and antibacterial, comfortable and breathable, moisture absorption and perspiration, and UV protection. With the development of people advocating nature and advocating green concepts, linen textiles are regarded as a symbol of human civilization and are widely used in clothing, decoration and other fields. [0003] Linen fabric is a textile obtained by spinning flax roving into spun yarn after boiling and bleaching, and then warping, sizing and weaving. In addition to the main component cellulose (71.58%), flax roving also contains a large number...
