Clean production method for bamboo fibres

Abstract

Disclosed is a dean production method for bamboo fibres, comprising the following steps: bamboo pieces are separated into filaments, and the filaments are twisted into ropes to obtain rope-shaped bamboo filaments; the rope-shaped bamboo filaments are refined by means of multiple alternating cold-hot treatments and rolling and rubbing to obtain coarse rope-shaped bamboo fibres (wherein same can be directly put into a drying device and then made into coarse bamboo fibres for a composite material); the coarse rope-shaped bamboo fibres are subjected to continuous biological degumming to obtain the rope-shaped bamboo fibres; the rope-shaped bamboo fibres are fed into a cleaning device for repeated cleaning, rolling and drying are performed, and then spraying-type oiling is performed to obtain thin rope-shaped bamboo fibres; finally, the thin rope-shaped bamboo fibres are subjected to opening and carding to make bamboo fibres for a textile material.

         1 . A clean production method for bamboo fibres, comprising:
 step 1, a step of separating into filaments and fouling into ropes: dividing a fresh bamboo material into equal bamboo strips, removing outer skins, inner skins and nodes from said bamboo strips to make bamboo pieces, and using a bamboo filament processing device to separate said bamboo pieces into filaments and twist said filaments into rope-shaped bamboo filaments; and   step 2, a step of microwave refining: feeding said rope-shaped bamboo filaments into a multiple refinement device by an automated delivery and buffer device to refine said bamboo filaments by an alternation of cold and hot treatments and processes of rolling and rubbing, and then feeding said bamboo filaments into a drying device, thereby obtaining coarse rope-shaped bamboo fibres for a composite material.   
     
     
         2 . The method as claimed in  claim 1 , wherein said step 1 includes using a filament separation device to separate said bamboo pieces into non-entangled filaments and using a rope fouling device to twist said filaments into continuous rope-shaped bamboo filaments. 
     
     
         3 . The method as claimed in  claim 1 , wherein in said step 2, said multiple refinement device includes ten to twenty pairs of grooved rollers and also includes a microwave heating device and a cold water spraying device alternating between every two pairs of said grooved rollers. 
     
     
         4 . A clean production method for bamboo fibres, comprising:
 step 1, a step of separating into filaments and forming into ropes: dividing a fresh bamboo material into equal bamboo strips, removing outer skins, inner skins and nodes from said bamboo strips to make bamboo pieces, and using a bamboo filament processing device to separate said bamboo pieces into filaments and twist said filaments into rope-shaped bamboo filaments;   step 2, a step of microwave refining: feeding said rope-shaped bamboo filaments into a multiple refinement device by an automated delivery and buffer device to refine said bamboo filaments by an alternation of cold and hot treatments and processes of rolling and rubbing, and then outputting coarse rope-shaped bamboo fibres;   step 3, a step of biological degumming: feeding said coarse rope-shaped bamboo fibres to a strip-shaped constant-temperature bio-enzyme fermentation pool by said automated delivery and buffer device and then outputting rope-shaped bamboo fibres after fomenting;   step 4, a step of cleaning and spraying oil: feeding said rope-shaped bamboo fibres to a cleaning device by said automated delivery and buffer device for repeated cleaning, rolling, and drying, with said cleaning device including a plurality of grooved rollers and a water spraying device, feeding said rope-shaped bamboo fibres to a drying device for a drying operation, then executing a process of spraying-type oiling after said drying operation, and thence outputting thin rope-shaped bamboo fibres; and   step 5, a step of opening and carding: feeding said thin rope-shaped bamboo fibres to an opening and carding device by said automated delivery and buffer device for smoothening and carding, thereby making bamboo fibres for a textile material.   
     
     
         5 . The method as claimed in  claim 4 , wherein said step 1 includes using a filament separation device to separate said bamboo pieces into non-entangled filaments and using a rope forming device to twist said filaments into continuous rope-shaped bamboo filaments. 
     
     
         6 . The method as claimed in  claim 4 , wherein in said step 2, said multiple refinement device includes ten to twenty pairs of grooved rollers and also includes a microwave heating device and a cold water spraying device alternating between every two pairs of said grooved rollers. 
     
     
         7 . The method as claimed in  claim 4 , wherein in said step 3, a bio-enzyme in said strip-shaped constant-temperature fermentation pool is a complex bio-enzyme composed of laccase and xylanase, having a ratio between 1:0.5 and 1:1, parameters applied to said fermentation pool being controlled by an enzyme concentration of bio-enzyme broth being between 2 g and 4 g per liter of water, a temperature of said bio-enzyme broth being between 45° C. and 65° C., a pH value of said bio-enzyme broth being between 4 and 6, and a dissolved oxygen concentration of said bio-enzyme broth being between 5.4 mg/L and 4.8 mg/L, any section of said rope-shaped bamboo fibres being fermented in said fomentation pool for 2 to 4 hours. 
     
     
         8 . The method as claimed in  claim 4 , wherein a conveyor belt is disposed in said strip-shaped constant-temperature fermentation pool and passes through an entire length of said fermentation pool for delivering said coarse rope-shaped bamboo fibres, said conveyor belt being submerged in fermentation broth and having an operation speed set according to a formula defined by v=l/t in which v represents a conveying speed, l represents an entire length of said fermentation pool, and t represents time required for fermentation, a liquid level detector being disposed in said fomentation pool, and a plurality of detecting signal stations being disposed along a length direction for detecting temperatures, pH values and dissolved oxygen concentrations respectively, thereby controlling and adjusting each parameter instantly.
