Production process for linen bamboo fibers, spinnable linen bamboo fibers and bamboo fiber yarns

Abstract

The invention relates to a production process for linen bamboo fibers, spinnable linen bamboo fibers and bamboo fiber yarns. The production process comprises the following steps: sawing a fresh bamboo into pieces according to a certain length and then respectively soaking the pieces in different biologic softening solutions or cooking the pieces in specially prepared softening solutions at high temperature; after cleaning the pieces, heating and airing the pieces, and then feeding the pieces into a bamboo mechanical splitting system, thereby preparing the linen bamboo fibers; processing the linen bamboo fibers into strip-shaped bamboo fiber spindles; putting the strip-shaped bamboo fiber spindles into an intelligent steam cooker in turn, thereby degumming, bleaching and cleaning the strip-shaped bamboo fiber spindles; after drying the strip-shaped bamboo fiber spindles, opening and removing impurities, thereby acquiring the spinnable linen bamboo fibers; and sending the spinnable linen bamboo fibers into a yarn-forming integrated system, and performing the processes of opening, cotton-blending, carding, drawing and yarn-forming, thereby finally acquiring the bamboo fiber yarns. The bamboo fibers prepared by using the production process are linen, longer, thinner, more uniform and softer. The average fineness of the bamboo fibers can reach 400-600 metric counts. The bamboo fibers can be purely spun or fully blended with fibers such as cotton, linen, and the like.

Description

【Technical field】 [0001] The invention relates to a production process for preparing hemp-shaped bamboo fiber, spinnable hemp-shaped bamboo fiber and bamboo fiber yarn from fresh bamboo through mechanical processing and physical and chemical modification. 【Background technique】 [0002] Bamboo fiber (also known as bamboo fiber) is a pure natural fiber produced by a combination of physical, mechanical and biochemical methods. It has been used in construction materials, paper industry, automobile manufacturing, sewage treatment, daily products and other industries, and has extremely broad application prospects in the textile field. [0003] With the breakthrough of the key technology of bamboo fiber, bamboo fiber is expected to become another "textile natural fiber" after cotton, wool, silk and hemp in the next 2 to 5 years and enter the textile market. At present, many enterprises, research institutions and universities in Zhejiang, Shanghai, Fujian, Jiangxi, Sichuan and oth...

Problems solved by technology

Because this method has only carried out sample experiment, the bamboo fiber of making can't be used for weaving, more can't carry out industrialization application promotion

[0005] In 2003, Yao Wenbin of Zhejiang Forestry College and others applied for the patent of "a preparation method of raw bamboo fiber" (patent authorization announcement number: CN100422396), and produced coarse bamboo fiber, semi-finish bamboo fiber, refined bamboo fiber and other products, but even Refined bamboo fiber, its fineness and uniformity are difficult to compare with cotton, hemp and other fibers, and basically cannot be used as textile fibers in the ordinary sense.

But so far these patents are also difficult to produce spinnable bamboo fiber, as yet no bamboo fiber yarn has been seen.

[0007] These above-mentioned production methods do not fully consider the particularity of the physical and chemical properties of bamboo and the non-uniformity characteristics of bamboo. They try to directly produce bamboo fiber through the scouring process by using the bamboo tow obtained after fiber opening. The bundle is crushed or broken, or the strength of the fiber is destroyed by chemical agents, resulting in poor quality of the bamboo fiber produced, the fiber is thick, short, hard, and its uniformity, length, fineness, strength and other indicators cannot reach the textile Due to fiber requirements, only low value-added products such as bamboo fiber decorative panels can be produced
