Bamboo Products Manufacturer Guide
In recent years, “bamboo fiber” products that claim to have antibacterial, deodorizing, moisture absorbing, and breathable effects have begun to flood the Chinese textile market. However, professionals say that all kinds of textiles made from regenerated cellulose fiber, viscose fiber, bamboo pulp fiber and bamboo charcoal fiber are artificially labeled as so-called “bamboo fiber” products, and the raw materials are not real bamboo. Fiber, products do not meet the Chinese national standard GB11951-89 “textile natural fiber terminology” definition, but these businesses use the bamboo fiber concept for promotional purpose to sell a good price, which seriously misled the ordinary customer’s Consumption mind.
The real bamboo fiber refers to bamboo original fiber, which is a bast fiber obtained from the stem of bamboo. It is also called natural bamboo fiber. It is a combination of mechanical and physical separation, chemical or biological degumming, and open combing. The natural fiber obtained by separation is the fifth largest natural fiber after cotton, wool, silk and hemp. It can be used in textile, non-woven, composite materials, building materials, environmental protection materials and other industries. In the United States, Canada, Japan, the European Union and many other countries and regions, it is clear that only bamboo fiber products can be named bamboo fiber
The bamboo pulp fiber on the market belongs to chemical viscose fiber. The bamboo is made into pulp in the paper mill, and then the pulp is made into bamboo pulp, which is then sent to the chemical fiber factory for wet spinning to make fibers. The production process is chemically sticky. Similar to the rubber fiber, the two chemical treatments before and after the loss of the bamboo’s natural properties are destroyed, mostly used in the textile industry, the English name is: Rayon from bamboo or Viscose from bamboo.
Bamboo charcoal fiber is made by the traditional chemical viscose preparation process. The nano-scale bamboo charcoal powder is surface-treated, and its slurry is added into the viscose through special process, and then drawn into the textile industry. The English name is: Bamboo charcoal viscose staple fiber.
The chemical constituents of bamboo fibrils are mainly cellulose, hemicellulose and lignin. The total amount accounts for more than 90% of the dry weight of bamboo, followed by protein, fat, pectin, tannin, pigment, ash, etc. The main substance of the fiber. At present, the products are generally classified into coarse bamboo fiber (long and short), spinnable bamboo fiber (cotton type, hemp type) according to the product’s coarse and slender short indexes; according to product use, it can be divided into bamboo fiber for textile (spinning, non-woven) ), composite bamboo fiber (composite materials, building materials).
The wide range and availability of bamboo resources, bamboo growth period is short, can be rapid growth and renewal, bamboo forest sustainable use and expanding. The product made of bamboo fiber can be naturally degraded in the soil, and it has no pollution to the environment after decomposition. It is a natural green and environmentally friendly raw material.
Therefore how do we evaluate the performance of bamboo fiber? According to years of research and practice, Zhang Yi, the founder of Bamboo Fiber Industry Network and the leader of bamboo fiber industrialization in China, has comprehensively compiled the top ten performances of bamboo fiber.
Performance 1: Antibacterial
Bamboo fiber has natural antibacterial and antibacterial effects, because bamboo contains a unique substance called “bamboo”, which 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. According to the test data of the National Textile Testing Center, the antibacterial properties of bamboo fiber against Staphylococcus aureus, Bacillus, and Candida albicans were 99%, 99.7%, and 94.1%, respectively.
Performance 2: Moisture Absorption and Ventilation
Observed under a 2000x electron microscope, the cross-section of the bamboo fiber is unevenly deformed, and is filled with an aperture similar to an elliptical shape. It is highly hollow and has a strong capillary effect, which can absorb and evaporate moisture in an instant. Bamboo fiber is the first of the five natural fibers in terms of moisture absorption and moisture permeability, and it’s gas permeability is 3.5 times stronger than cotton. It is known as “breathing fiber”
Performance 3: UV resistance
Bamboo fiber contains natural chlorophyll copper sodium, which is a safe and excellent UV absorber. It has been tested by Shanghai Institute of Physics, Chinese Academy of Sciences. For 200~400nm UV, the penetration rate of cotton is 25%, and the penetration rate of bamboo fiber is insufficient. 0.6%, its UV resistance is 41.7 times that of cotton. Ultraviolet rays of this wavelength are the most harmful to the human body, which is unmatched by other fibers.
Performance 4: Natural Health
There are 24 chapters in the “Compendium of Materia Medica” that explain the different medicinal functions and prescriptions of bamboo, and nearly 1,000 kinds of folk medicines. Bamboo is rich in trace elements, and the antioxidant compounds in bamboo fiber can be physically removed to effectively remove free radicals in the human body. It has anti-aging biological effects; bamboo fiber contains ester peroxygen compounds to block strong carcinogens N – Ammonia nitrite compound, significantly improve the body’s immunity; bamboo fiber also has the effect of moisturizing the skin and anti-fatigue, can increase the body’s microcirculation blood flow, activate tissue cells, make the body produce a warming effect, can effectively regulate the nervous system, Dredge the meridians.
Performance 5: Heat Storage and Warmth
The cell structure of bamboo fiber is hollow thin-walled multi-tube structure, which has a strong sponge effect, which can effectively improve the heat reflection efficiency and slow down the heat decay, so that the bamboo fiber products are always warm, dry and comfortable.
Performance 6: Shock Absorption And Noise Reduction
Bamboo fiber has good strength and toughness, and has a large number of micropores and gaps inside. These micropores are small, evenly distributed and interpenetrating, and are not closed. They have unique internal structures such as flow resistance, pores and elasticity. It plays the role of shock absorption and noise prevention.
Performance 7: Anti-mold and Anti-Mite
Bamboo fiber is a mechanical processing of bamboo, which is degummed and softened by thermal means, so that microorganisms and bacteria lose their breeding and implantation environment. According to the automotive interior inspection standard, the bamboo fiber felt and jute felt were tested by mildew test. The results showed that the bamboo fiber felt did not show any mildew, and the jute felt was not resistant to mildew after treatment with mildew and preservatives. Bamboo fiber felt
Performance 8: Antistatic Radiation Protection
Bamboo fiber itself does not have a free charge, so it has anti-static ability, which can absorb and shield the bamboo fiber application products and prevent radiation.
Performance 9: 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. Due to the special substance of “chlorophyll copper sodium” in bamboo fiber, it also has a good deodorizing effect. Experiments show that the deodorization rate of bamboo fiber to ammonia gas is 70% to 72%, and the deodorization rate of acid odor is 93% to 95%.
Performance 10: Sound Insulation
Studies have shown that the individual bubbles and closed gaps do not function as sound absorption. Under the same porosity, the larger the pore size, the larger the thermal conductivity, and the higher the thermal conductivity of the interconnected pores than the closed pores. The thin and hollow porous structure of bamboo fiber cells makes them have strong sound insulation and heat insulation capabilities
