Bamboo fiber is the fifth largest natural fiber extracted from naturally grown bamboo, followed by cotton, hemp, wool, and silk. Bamboo fibrils have good gas permeability, instant water absorption, strong abrasion resistance, and good dyeability, and have natural antibacterial, antibacterial, antimony, deodorant, and anti-ultraviolet functions.
The chemical constituents of bamboo fibrils are mainly cellulose, hemicellulose, and lignin. The three are homopolysaccharides, and the total amount is more than 90% of the fiber dry mass, followed by protein, fat, pectin, tannin, pigment, Most of the ash, etc., are present in the cell lumen or in special organelles, directly or indirectly involved in their physiological effects.
Cellulose is the main substance that makes up bamboo fibril cells, and it is also the meaning of it as a textile fiber. Due to the difference in bamboo age, the cellulose content is also different, such as 75% for bamboo and bamboo, 66% for 1 year, and 58% for 3 years. The hemicellulose content in bamboo fibrils is generally 14% to 25%, and the average content of bamboo is about 22.7%, and its content also decreases with the increase of bamboo age, such as 24.9% of bamboo grown in 2 years. 4 years old, 23.6%.
Natural bamboo fiber
Natural bamboo fiber is mainly bamboo fiber. Bamboo fibrils are natural bamboo fibers obtained by a combination of physical and chemical methods.
Chemical bamboo fiber
Chemical bamboo fiber can be classified into bamboo pulp fiber and bamboo charcoal fiber.
Bamboo pulp fiber: Bamboo pulp fiber is a kind of pulp made of bamboo, then the pulp is made into pulp and then wet-spun into the fiber. The manufacturing process is basically similar to that of glue.
Bamboo charcoal fiber: It is a fiber product which is selected from nanometer bamboo charcoal powder and added to viscose spinning solution through a special process and then weaved by a similar conventional spinning process.
Observed by scanning electron microscopy, the bamboo fibrils have transverse sections in the longitudinal direction, the thickness distribution is very uneven, and there are numerous fine grooves on the fiber surface. The transverse direction is an irregular elliptical shape, waist round shape, etc., and there is a middle cavity. The cross section is covered with large and small gaps, and the edges are cracked, which is similar to the cross-section of ramie fiber.
Average fineness: 6dtex
Average strength: 3.49CN/dtex
Average length: 95mm
- 1. Bamboo fiber yarn is used for clothing fabrics, mats, bed sheets, curtains, scarves, etc. If it is blended with nylon, it can produce light and thin fabrics.
- Blended with cotton, wool, hemp, enamel, and chemical fiber, used for weaving or knitting, producing woven fabrics and knitted fabrics of various specifications. Woven fabrics can be used to make curtains, jackets, casual wear, suits, shirts, sheets and towels, bath towels, and more. Knitted fabrics are suitable for making underwear, sweatshirts, T-shirts, socks, etc.
- Bamboo-cotton blended yarn with bamboo fiber contains less than 30% is more suitable for underwear and socks, and can also be used for making medical care products.
- It has also been used in the manufacture of paper towels. In recent years, healthy and environmentally friendly bamboo fiber natural paper towels with bamboo fiber as raw materials have begun to appear.
- Moisture absorbing
Observed under the 2000x electron microscope, the cross-section of the bamboo fiber is unevenly deformed, filled with pores similar to an elliptical shape, and is highly hollow. The capillary effect is extremely strong, and the moisture can be absorbed and evaporated instantaneously. Among all the natural fibers, bamboo The fiber’s moisture absorption and moisture permeability are among the top five fibers, and the far-infrared emissivity is as high as 0.87, which is much better than traditional fiber fabrics, so it is in line with the characteristics of thermal comfort. At a temperature of 36 ° C and a relative humidity of 100%, the moisture regain of bamboo fiber is more than 45%, and the gas permeability is 3.5 times stronger than that of cotton. It is known as “breathing fiber” and is also called “fiber queen”. “.
According to the needs of different seasons, using different techniques, bamboo fiber products in the summer, the human body will feel cool, 1-2 degrees lower than the temperature of wearing ordinary clothes, and in the winter and spring seasons use both fluffy and warm, and can eliminate excess body Hot air and moisture, do not get angry, do not dry, winter warm and cool summer is not comparable to other fibers, textiles made with it are called “human second skin.” At the same time, bamboo fiber products have excellent skin-friendly properties, soft touch, and refreshing skin feel. Bamboo fiber products are fluffy and light, lubricated and delicate, soft and light, with cotton-like softness, silky smoothness, soft and close-fitting, friendly skin, good drape, giving a zero-pressure comfort.
- Antibacterial and antibacterial
Bamboo fiber products have natural antibacterial, antibacterial and bactericidal effects. Because bamboo has a unique substance, the substance is named “bamboo” and has natural antibacterial, anti-mite, deodorant, and anti-insect functions. Under the microscope, the bacteria can multiply in cotton, wood and other fiber products, and the bacteria on the bamboo fiber products can not only survive for a long time but also disappear or reduce in a short time, the bacterial mortality rate reaches 75% within 24 hours. the above. The new findings of Japanese authorities have added value to this product, and the results have been confirmed by the China Cotton Textile Product Quality Supervision and Inspection Center and the Shanghai Institute of Microbiology of the Chinese Academy of Sciences (the cotton towel is stinky in summer). The result of thousands of times of bacterial reproduction). The cotton product itself does not have antibacterial and antibacterial functions. The reason why it is mildewed, odorous and sticky is the result of the bacteria multiplying on the towel. The reason why bamboo fiber towel does not occur is mainly that it has antibacterial and antibacterial functions, and bacteria cannot breed on it or even survive. Therefore, the bamboo fiber towel does not mold, taste, or stick even in a warm and humid environment.
The extensiveness and availability of resources are mainly reflected in the short growth period of bamboo, which can be completed in 2-3 years and long-term operation in one planting. Bamboo can grow up to 3 feet in height overnight. It can grow and renew quickly and can replace Cotton, wood and other resources, sustainable use. The products made of bamboo fiber can be naturally degraded in the soil, and there is no pollution to the environment after decomposition. It is a natural, green and environmentally friendly textile raw material.
- Natural health care
There are 24 chapters in the “Compendium of Materia Medica” that explain the different medicinal functions and prescriptions of bamboo. The folks have prescriptions for nearly a thousand kinds of bamboo. Modern medicine believes that the antioxidant compounds in “Bamboo Element” can effectively remove free radicals and ester peroxy compounds in the body, and can block the strong carcinogen N-nitrite compound, which can not only significantly improve the body’s immunity. It also has the biological effect of moisturizing the skin and resisting fatigue and anti-aging. Due to the natural antibacterial function of bamboo fiber products, the products produced do not need to add any synthetic antibacterial agents, and will not cause skin allergies. It can significantly improve the body’s immunity, and it also has the biological effect of nourishing the skin and resisting fatigue and anti-aging. It is a truly pure natural green health product.
- Deodorization adsorption
The special ultra-fine microporous structure inside the bamboo fiber makes it have strong adsorption capacity and can absorb harmful substances such as formaldehyde, benzene, toluene, and ammonia in the air, and eliminate bad odor.
