Embodiment 1

[0027] The hemp fabric in this embodiment is ramie fine cloth with a pulp content of 8.0%.

[0028] A biological enzyme pretreatment method for hemp fabric, comprising the following steps:

[0029] (1) Pretreatment: At room temperature, put the hemp fabric to be treated into the pretreatment solution, turn on the stirring device to stir, so that the pretreatment solution and the fabric are evenly mixed, then raise the temperature to 75°C, keep it warm for 60min, and then drain the solution . Wherein, the pretreatment solution is deionized water

[0030] (2) Biological treatment: control the temperature to 40°C, place the biological treatment solution in the device; turn on the stirring device to stir, so that the biological treatment solution and the hemp fabric are evenly mixed, the pH of the solution is controlled to be 6.5, and then the temperature is raised to 50°C, Keep the hemp fabric below the liquid level and keep it warm for 60 minutes; when inactivating the enzyme,...

Abstract

The invention discloses a bio-enzyme pretreatment method of linen fabric. The method comprises the steps of firstly, pretreating the linen fabric to be treated, then carrying out biological treatmenton the pretreated linen fabric by using compound bio-enzyme, carrying out bleaching pretreatment, then treating by using hydrogen peroxide bleaching liquid and washing, and finally carrying out smoothing or softening treatment. The linen fabric treated by using the method is free from residual impurities, low in loss of strength and good in hand feeling. Compared with the traditional technology, the method adopts a bio-enzyme technology, so that the pollutant emission is obviously reduced, the environment is better protected, and the consumption of water for cleaning the linen fabric can be reduced.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing in the textile industry, in particular to a biological enzyme pretreatment method for linen fabrics. Background technique [0002] Hemp fiber is a natural cellulose fiber, which has 15%-25% lower cellulose content, 5%-6% higher lignin content and 0.9%-1.8% higher waxy content than cotton fiber. These natural cellulose fibers, in addition to their own natural impurities, also have additional impurities such as various pulps and oil stains contaminated during processing. In the weaving process, since the warp yarns of the fabric must be sized before weaving, there are many additional impurities remaining in the woven fabric, such as polyvinyl alcohol slurry, starch slurry and other sizing. The presence of these impurities seriously affects the wetting properties of the fabric, makes the fabric hydrophobic, and affects the subsequent dyeing and finishing of the fabric. Therefore, the f...
