Problems solved by technology

There are several patent documents in the prior art to record the processing method of spinnable bamboo raw fiber, but there are few records about the fineness, strength and other indicators of bamboo fiber. Only CN 1208505C discloses that the average fineness is about 1687 public branches. fiber and its processing method, but it is difficult for those skilled in the art to implement the invention according to the contents disclosed in the specification, and the cooking process involved in the method needs to be carried out in a pressure vessel, which is inconvenient to implement
The processing method of bamboo fiber of Chinese patent CN1621580A, CN 1624212A and CN 1600907A relates to enzyme treatment process, but does not disclose the kind of enzyme in CN 1621580A; ) aqueous solution to treat bamboo joints, but these documents do not clearly disclose the purpose of the enzyme treatment process, the specific operating conditions and the technical effects achieved.

Embodiment 1

[0048] Example 1 Production of bamboo fiber

[0049] 1. Pretreatment: Remove branches and tips of moso bamboo with a growth period of 1 to 2 years, discard the part 20 cm close to the root, and cut into bamboo tubes according to the natural length of the bamboo joints, the length is about 20 cm, and then hit the bamboo. After the machine crushes the bamboo tube and removes the bamboo spring, a bamboo sheet with a width of about 2 cm is made;

[0050] 2. Soaking: Lay the prepared bamboo slices as regularly as possible, and soak in a neutral solution containing 0.01% (w / w) JFC-BX mixed penetrant for 10 to 11 hours;

[0051] 3. Steaming: Steam the soaked bamboo chips at 100℃ for 3 hours under normal pressure. The cooking liquid is an aqueous solution of caustic soda (NaOH), which contains penetrant, and the concentration of penetrant is 1% (w / w) Around, the said penetrant is a JFC-BX hybrid penetrant, the pH of the cooking liquid is 13, and the volume ratio of the cooking liquid to t...

Embodiment 2

[0058] Example 2 Production of pure bamboo yarn

[0059] The natural bamboo fiber pure bamboo yarn (40-70 public counts) is prepared from the bamboo fiber of the present invention by adopting the stretched sliver spinning process after drawing and cutting. The textile technology and textile equipment used in the present invention are the textile technology and textile equipment conventionally used in the textile industry. The specific spinning process is as follows:

[0060] Draft cutting → fiber sorting, weighing → stretching (2 passes) → sliver → needle comb (4 passes) → roving → spinning

Abstract

The present invention discloses one kind of spinnable natural bamboo fiber and its production process and application. The natural bamboo fiber has a fineness of 1600-1900 counts and a length of that between bamboo joints. The production process includes the steps of the pre-treatment of bamboo, the bamboo fiber treating and the post-treatment of bamboo fiber. The step of bamboo fiber treating includes soaking, steaming at normal pressure, rolling, neutralizing and water washing, enzyme treating with amylase, the secondary steaming and the secondary water washing. The natural bamboo fiber produced based on the process of the present invention is superior in fineness, strength, etc. and can meet the requirement of textile in producing high quality yarn and fabric.

Description

Technical field [0001] The present invention relates to bamboo fiber and its processing method, and the application of the bamboo fiber. Specifically, the present invention relates to a spinnable, high-fineness natural bamboo fiber and its processing method, and the application of the bamboo fiber. Especially yarns and fabrics produced from said bamboo fibers. Background technique [0002] In recent years, with the improvement of people's living standards, the pursuit of comfort and returning to nature has become a new fashion in household goods and clothing. In the textile industry, textile fibers are divided into two types: natural fibers and chemical fibers. Although fabrics made of chemical fibers have the advantages of wear resistance, stiffness, and not easy to wrinkle, they have disadvantages such as poor comfort and poor air permeability. On the contrary, fabrics made of natural fibers have good moisture conductivity and breathability, and are comfortable to wear, so they...
