Problems solved by technology

[0003] Most of the degumming of natural bamboo fiber is chemical degumming, but it will cause pollution to the environment
Therefore, the industry turned to the exploration of biological degumming. The existing technology more or less always uses chemicals, that is, degumming in the way of biology and chemistry, which cannot achieve clean production.
In the preparation process, the chemical softening and degumming of bamboo chips are mostly used as the starting point, which is unreasonable in the utilization of bamboo resources, which not only increases the production links, increases energy consumption and environmental pollution, but also increases the processing of bamboo fiber. cost

[0041] First Example: Processing Coarse Bamboo Fibers for Composite Materials

[0042] Step 1: Divide the fresh bamboo into bamboo strips, remove bamboo green, bamboo yellow, and bamboo knots, and make bamboo slices, use the splitting equipment to make bamboo slices into bamboo threads that are not involved with each other, and then twist them by the rope forming device into continuous rope-like bamboo filaments. The equivalent diameter of the main body of the bamboo wire is 0.5 mm.

[0043] Step 2: The rope-like bamboo filament is fed into the multiple microwave refinement equipment with 10 pairs of grooved rollers by the automatic conveying and buffering device. Between every two pairs of grooved rollers, a microwave heating device and a cold water shower device are arranged alternately to Repeated rolling, heating, rolling, and cooling, that is, alternating cold and heat plus rolling. The conveying speed is mastered in 30 minutes according to the processing time of any se...

[0045] The second embodiment: as figure 1 shown, processing bamboo fibers for textile nonwovens

[0046] Step 1: Divide the fresh bamboo into bamboo strips, remove bamboo green, bamboo yellow, and bamboo knots, and make bamboo slices, use the splitting equipment to make bamboo slices into bamboo threads that are not involved with each other, and then twist them by the rope forming device into continuous rope-like bamboo filaments. The equivalent diameter of the main body of the bamboo wire is 0.5 mm.

[0047] Step 2: The rope-like bamboo filament is fed into the multiple microwave refinement equipment with 15 pairs of grooved rollers by the automatic conveying and buffering device. Between every two pairs of grooved rollers, a microwave heating device and a cold water shower device are arranged alternately, that is, Rolling, heating, rolling, and cooling are repeated, that is, alternating cold and heat plus rolling. The conveying speed is controlled in 45 minutes according ...

[0054] Third Example: Processing Bamboo Fibers for Spinning Woven Materials

[0055] Step 1: Divide the fresh bamboo into bamboo strips, remove bamboo green, bamboo yellow, and bamboo knots, and make bamboo slices, use the splitting equipment to make bamboo slices into bamboo threads that are not involved with each other, and then twist them by the rope forming device into continuous rope-like bamboo filaments. The equivalent diameter of the main body of bamboo wire is 0.5mm.

[0056] Step 2: The rope-like bamboo filament is fed into the multiple microwave thinning equipment with 20 pairs of grooved rollers by the automatic conveying and buffering device. Between every two pairs of grooved rollers, a microwave heating device and a cold water shower device are arranged alternately, that is Rolling, heating, rolling, and cooling are repeated, that is, alternating cold and heat plus rolling. The conveying speed is controlled by 60 minutes according to the processing time of any...

Abstract

A bamboo fiber clean-production method comprises the following steps that 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 adopting the modes of multiple cold-hot alternation and rolling and rubbing to obtain coarse rope-shaped bamboo filaments (can be directly put into a drying device and then made into coarse bamboo fiber for a composite material); the rope-shaped bamboo filaments undergo continuous biological degumming to obtain the rope-shaped bamboo filaments; the rope-shaped bamboo filaments are fed into a cleaning device for repeated cleaning, rolling and drying are performed, and then spraying-type oil supply is performed to obtain thin rope-shaped bamboo filaments; finally, the thin rope-shaped bamboo filaments are opened and carded to make bamboo fiber for a textile materials. The bamboo fiber clean-production method can achieve automatic and continuous processing, adopts no chemical, is clean, saves energy and is environmentally friendly.

Description

【Technical field】 [0001] The invention relates to the clean production of natural bamboo fiber, in particular to prepare natural bamboo fiber by means of continuous production line, physical processing of cold and heat, automatic control of biological degumming parameters, no chemicals, no pollution, clean and environment-friendly, energy-saving and high-efficiency technology field. 【Background technique】 [0002] Bamboo fiber (natural bamboo fiber, also known as bamboo fiber) belongs to plant stem woody fiber, and its cellulose is wrapped in lignin and hemicellulose, but the length of a single fiber is only about 2mm. This just makes when producing the bamboo fiber that textile material is used, can not take the mode of complete degumming, but processes with semi-degumming mode, to obtain the natural bamboo fiber of fiber bundle state. [0003] Most of the degumming of natural bamboo fiber is chemical degumming, but it will cause pollution to the environment. Therefore, t...
