Problems solved by technology

Although the single above-mentioned two methods can achieve the purpose of peeling, there are still a series of problems, such as uneven peeling, irregular scale removal, serious damage to strength, decreased hand feeling, and environmental pollution.
Although biological enzyme treatment will not pollute the environment, the peeling effect of a single enzyme treatment is not good, and multiple compound enzyme treatments increase the cost
Using a combination of chemical and biological treatment, deposits will appear on the fabric, which will affect the dyeing

Embodiment 1

[0020] Strain Stenotrophomonas maltophilia DHHJ (CGMCCNo.2231), beef extract 5g / L, peptone 10g / L, NaCl 5g / L, agar 20g / L, pH7.4-7.6, liquid medium is beef extract 5g / L, peptone 10g / L, NaCl 5g / L, pH7.6. Fermentation medium components and dosage are glucose 10g / L, casein 2g / L, KCl0.4g / L, NaCl0.3g / L, NaCl 2 HPO 4 4g / L, KH 2 PO 4 0.3g / L, Tween-804g / L, pH7.5. Add 1% Stenotrophomonas maltophilia and 10% wool cloth to the fermented medium that has been prepared and sterilized, adjust the fermentation temperature to 30°C, the rotation speed to 300r, the fermentation time to 96h, and adjust the appropriate air pressure Strictly carry out the fermentation according to the amount of ventilation. After the end, rinse the fabric with hot water at 40°C, change the water for 20 minutes, 30 minutes, and 30 minutes for washing, and dry it naturally for later use. Among them, the SEM image of the wool cloth before dyeing after bacterial treatment is as follows figure 1 shown.

Abstract

The invention relates to a biological treatment method for wool blend fabric. The method includes the steps of adding stenotrophomonas maltophilia in a sterilized fermentation medium, adding the wool blend fabric, regulating the fermentation temperature to 30-40 DEG C, regulating the rotating speed to 200-400 rmp, regulating the fermentation time to 48-96 h, flushing the fabric, and airing the fabric. Application objects of the method are within a broad range. Wool fiber scales of the fabric processed according to the method are completely stripped off, the rest of fiber is not influenced, the dyeing performance is remarkably improved, the dyeing temperature is lowered, the dyeing rate is increased, and the fuzzing and pilling performance is lowered.

Description

technical field [0001] The invention belongs to the field of processing methods of wool blended fabrics, in particular to a biological treatment method of wool blended fabrics. Background technique [0002] Wool fiber is one of the important textile fibers. The surface is covered with hard and dense scales, which not only affect the wearability of the fabric, such as poor dimensional stability, rough hand feeling, easy to pilling, bulky and thick, etc., but also bring great benefits to the printing and dyeing field. Difficulties, mainly manifested in slow dyeing rate and high dyeing temperature. The traditional method dyes under boiling conditions. On the one hand, energy consumption such as electricity and water is serious. On the other hand, the strength of the fabric after high temperature treatment is seriously reduced, and the bulkiness is reduced. Therefore, in recent years, people have studied the mild treatment method of wool fiber and its fabric, so that it can not ...
