US 2019/0264350 A1 · 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.

Dependent claims

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.

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.
