Embodiment 1

[0039] Embodiment 1: the extraction method of bamboo shoot shell fiber for spinning, it may further comprise the steps:

[0040] 1) pretreatment: bamboo shoot shells (may include bamboo shoot shells of various bamboos) are cut into 60mm lengths, sealed and stored, adjusted to humidity, and controlled moisture regain to 6.5%;

[0041] 2) degumming treatment: degumming treatment adopts two kinds of combinations;

[0042] (1) Steam explosion treatment: put the pretreated bamboo shoot shells into a steam explosion tank, and use steam explosion conditions: pressure at 1.0Pa, temperature at 180°C, and time at 5 minutes; when the time comes, the pressure is released instantaneously for steam explosion treatment ;

[0043] (2) Microbial treatment:

[0044] The bamboo shoot shell after the steam explosion treatment is adjusted to be 80% water content (weight), then add replenishment liquid (or claim culture liquid); The replenishment liquid is glucose and urea, glucose and urea weight ...

Embodiment 2

[0056] Embodiment 2: the extraction method of bamboo shoot shell fiber for spinning, it may further comprise the steps:

[0057] 1) Pretreatment: cut the bamboo shoot shells into 100mm lengths, seal them for storage, adjust the humidity, and control the moisture regain to 8%;

[0058] 2) degumming treatment: degumming treatment adopts three combinations;

[0059] (1) Steam explosion treatment: put the pretreated bamboo shoot shells into a steam explosion tank, and use steam explosion conditions: pressure at 2.0Pa, temperature at 160°C, and time at 8 minutes; when the time comes, the pressure is released instantaneously for steam explosion treatment .

[0060] (2) Microbial treatment:

[0061] The bamboo shoot shell after the steam explosion treatment is adjusted to have a water content (weight) of 80%, and then add replenishment liquid; 2% of bamboo shoot shell weight; Carry out bacterial classification degumming again:

[0062] ① Select Phanerochaete chrysosporium as the ...

Embodiment 3

[0083] Embodiment 3: the extraction method of bamboo shoot shell fiber for spinning, it may further comprise the steps:

[0084] 1) pretreatment: cut the bamboo shoot shells into 20mm lengths, seal them for storage, adjust the humidity, and control the moisture regain to 6%;

[0085] 2) degumming treatment: degumming treatment adopts steam explosion treatment;

[0086] Steam explosion treatment: put the pretreated bamboo shoot shells into a steam explosion tank, and use steam explosion conditions: pressure at 1.0Pa, temperature at 160°C, and time at 4min to obtain degummed bamboo shoot shell fibers;

[0087] 3) Post-processing:

[0088] (1) the bamboo shoot shell fiber after the degumming process is irradiated with cobalt-60 rays, and the irradiation amount is 2kgy to obtain the radiation-cured bamboo shoot shell fiber;

[0089] (2) oiling; the radiation-cured bamboo shoot shell fiber adds and crude oil, and the addition weight of crude oil is 1% of the radiation-cured bambo...

Abstract

The present invention relates to a method for extracting spinning fiber from bamboo shoot shells. The extracting method of spinning fiber from bamboo shoot shells is characterized in that the present invention comprises the following steps: firstly, pretreatment: cutting the bamboo shoot shells into pieces 20-100mm long; storing the pieces in a sealed environment and adjusting the humidity to control the moisture regain rate at 6 percent -10 percent; secondly, degumming treatment: using one or combination of any two or three of steam explosion treating method, microbial treating method and chemical treating method for degummed bamboo shoot shell fiber; thirdly, post-treatment: a, oil feeding: adding wool oil to the degummed bamboo shoot shell fiber, the wool oil being 1-2 percent of the degummed bamboo shoot shell fiber in weight; b, drying: controlling the temperature of the drying oven at 60-80 DEG C; c, fiber dispersing: obtaining spinning bamboo shoot shell fiber. The present invention has the advantages of simple process and low cost and, applied to textile processing, can take full use of bamboo shoot shell resources and protect the environment.

Description

technical field [0001] The invention relates to a method for extracting fibers for spinning from bamboo shoot shells. Background technique [0002] Over the past few decades, the rapid development of science and technology has not only brought progress to society, but also brought unprecedented harm to human beings. Natural phenomena such as climate warming, acid rain and floods, land desertification, and destruction of the ozone layer have warned that human beings must pay attention to the earth's environment. issues are given attention. The ecological environment of textiles has also attracted widespread attention. With the promotion of the concept of ecological textiles on a global scale, the green consumption pattern will surely become the leading consumption pattern of textiles. While improving the quality of human life, it will also contribute to the sustainable development of the global economy. Development has a positive and far-reaching impact. For China, accelera...
