Problems solved by technology

[0005] Chinese patent CN 100487173C discloses natural bamboo fiber and its processing method. Although the natural bamboo fiber obtained has significant advantages in terms of fineness and strength, the fineness of the obtained bamboo fiber is 5.46dtex, and the strength is 5.31 (cN / dtex), but the processing method uses chemical methods such as neutralizing water washing and enzyme treatment, and it is not natural bamboo fiber prepared by purely physical methods, and some natural characteristics of bamboo fiber are destroyed.
[0006] In the 2007 master's thesis of Beijing Institute of Fashion Technology, in the article "Preparation of Bamboo Fiber for Weaving and Research on its Structural Properties" published by Han Xiaojun, it was publicly released that the water retention rate of bamboo fiber was as high as 130.57%, which needs attention, but with As the degree of degumming increases and the fiber surface smoothness improves, the water retention rate of bamboo fiber will decrease.

Abstract

The invention provides a physical preparation method of natural bamboo fibers. Through original bamboo cutting, rolling and slicing, dipping, primary high temperature and high pressure cooking, water washing, rolling and splitting, secondary high temperature and high pressure cooking, secondary water washing, ultrasonic vibratory splitting, bamboo fibers combing as well as screening and drying procedures, the natural bamboo fibers are prepared by using middle materials of Hunan annual moso bamboos as raw materials for preparing the natural bamboo fibers. By using the physical preparation method of the natural bamboo fibers, provided by the invention, the bactericidal capability of the bamboo fibers are improved while natural antibacterial, bacteriostatic, mothproofing, deodorant and ultraviolet resistant functions of the bamboo fibers are kept; and obvious breakthrough are made in fineness, strength, residual gum content and other aspects of the made 100% natural bamboo fibers.

Description

technical field [0001] The invention relates to a physical preparation method of natural bamboo fiber, which belongs to the field of bamboo fiber. Background technique [0002] Bamboo fiber is a new type of cellulose fiber developed and industrialized by my country. According to different processing methods, there are two types of bamboo fiber and bamboo pulp fiber. Bamboo fiber is processed by physical methods without adding any chemical reagents, and is 100% natural fiber. Bamboo pulp fiber is processed by chemical method, hydrolyzed (alkali method) and multi-stage bleaching to make pulp, and then spun by chemical fiber factory to make bamboo pulp fiber, which is a chemical spinning process similar to viscose fiber. [0003] Bamboo fiber is a pure natural fiber with excellent fiber performance, the product has a special style, and has excellent antibacterial properties, and it is dry and comfortable in summer. Bamboo pulp fiber is greatly damaged in performance due to th...
