NOVELTY - Bacterial strains of Bacillus species preserved under preservation number CGMCC No. 5971, Pseudomonas fluorescens preserved under preservation number CGMCC No. 5974 and Wickerhamomyces anomalus preserved under preservation number CGMCC No. 5975, are new.    USE - For producing textile fiber (claimed) used in the manufacture of fabric.    ADVANTAGE - The textile fiber production method does not pollute the environment, directly converts waste liquid into organic fertilizer, realizes zero discharge and zero pollution, provides biological treatment process to protect the fiber; as compared with the traditional chemical method it exhibits low production cost and high economic benefits; saves energy; is environment-friendly; improves the utilization ratio of raw material; and reduces production cost. The fiber is ecological and provides environment protection and exhibits excellent properties.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing textile fiber involving forming bacterial liquid by configuring the above bacterial strains to composite bacterial aqueous solution according to the following weight ratio of bacteria liquid: Bacillus species:Pseudomonas fluorescens:Wickerhamomyces anomalus of 2-3:1-2:2-3; taking raw materials, cutting the raw materials into two sections, putting the raw materials into a soaking pool and allowing them to swell, preparing seal coat of fiber by soaking the solution of raw materials into the prepared bacterial liquid, sterilizing by taking out the biodegradable raw material from bacteria liquid, draining, steam sterilizing, drying the sterilized raw material for the first time period to form fiber, subjecting second section of fiber bundle to fine grinding to make fiber beam be separated into single fiber, screening, filtering after a period of grinding, forming slurry after the second fine grinding of the fiber bundle, and then grinding to make it into single fiber, drying, soaking the prepared fiber in warm water, and then drying, and carding to form textile fiber.    DESCRIPTION OF DRAWING(S) - The figure shows flow diagram illustrating method for producing textile fibers.
