Embodiment 1

[0026] Example 1 Configuration of Bacteria Solution

[0027] The biological bacteria used in the present invention have been preserved on April 6, 2012 at the General Microorganism Center (CGMCC, No. 3, No. 1, Beichen West Road, Chaoyang District, Beijing) of the China Microbiological Culture Collection Management Committee, and the preservation number is CGMCC. Bacillus sp. No.5971, Pseudomonas fluorescens with CGMCC No.5974, Wickerhamomyces anomalus with CGMCC No.5975.

[0028] The above-mentioned composite bacteria group is configured into a composite bacteria aqueous solution according to the following mass ratio, which is the bacterial solution:

[0029] Bacillus: Pseudomonas fluorescens: Wickerhamomyces anomalus is 2-3:1-2:2-3; the density of the formed bacterial liquid is more than 60 million bacteria / ml, for later use.

Embodiment 2

[0030] Example 2 Preparation of fibers from flax

[0031] Using flax as raw material, specify the preparation method of the fiber. The composite flora is configured according to the following mass ratio: Bacillus: Pseudomonas fluorescens: Wickerhamomyces anomalus is 3:2:3.

[0032] For details, please refer to figure 1 , The process flow of the fiber preparation method is divided into three stages: a preparation stage, a fiber section and a by-product section.

[0033] (1) Preparation stage: 1, 4

[0034] Immerse the harvested flax in the soaking bin or soaking tank for washing and cold soaking. First, wash away the soil and other sundries on the surface of the raw material, and soak at the same time. The water temperature is natural temperature, and the time is based on soaking and swelling. 10-12 Hour. After repeated immersion, the liquid becomes turbid, and the supernatant after flocculation and precipitation can be used again. The sediment is input into the digester f...

Embodiment 3

[0048] Example 3 Preparation of cellulose from ramie

[0049]The specific preparation process is the same as in Example 2. The difference is that the composite flora is configured according to the following mass ratio: Bacillus: Pseudomonas fluorescens: Wickerhamomyces anomalus is 3:2:2; during biodegradation, the mass ratio of the raw material after decompression to the bacterial liquid is 1 :7.

[0050] Please refer to Table 1 for the measurement results of the physical performance indexes of the obtained fibers.

Abstract

The present invention relates to a composite flora and an application of the composite flora in textile fiber preparation. The composite flora comprises bacillus sp. with a preservation number of CGMCC No.5971, pseudomonas fluorescens with a preservation number of CGMCC No.5974, and Wickerhamomyces anomalus with a preservation number of CGMCC No.5975. The method comprises the following steps: preparing a bacterial liquid; treating raw materials; and preparing fibers, wherein fiber preparation comprises biodegradation, steam sterilization, fiber obtaining, drying, and combing. According to the present invention, the method does not pollute the environment, a waste liquid is directly converted into an organic fertilizer so as to achieve zero emission and zero pollution, the biological treatment process provides a protection effect for fibers, advantages of low production cost and high economic benefits are provided compared with the traditional chemical method, and characteristics of energy source saving and environmental protection are provided.

Description

technical field [0001] The invention relates to a textile fiber, in particular to a composite bacterial flora and its application in preparing the textile fiber. Background technique [0002] In recent years, with the depletion of petrochemical resources, hemp fiber has been favored by consumers due to its ecological and environmental protection characteristics. Its demand is increasing year by year, and the annual growth rate of global natural fiber is 8%. The biggest feature of hemp fiber raw material is high fiber content, long and slender fiber is conducive to interweaving, good strength; fiber cell cavity is small, cell wall thickness, wall-to-cavity ratio is large; hemp fiber cell cavity and fiber are thin, so the opacity is high. But its disadvantage is that the fibers are not easy to separate, so that the air permeability of the fabric is low. [0003] In the prior art, fibers are prepared from hemp raw materials through chemical methods, and the waste liquid genera...
