Most of the traditional cellulose fibers are processed by using cotton and wood pulp as raw materials. With the massive deforestation of wood and the slowing of the growth of cotton fiber, the raw material resources of plant cellulose fiber are seriously deficient. The world's countries pay more and more attention to the living environment, to protect the ecological environment, and to limit the deforestation of trees. As the main raw material of cellulose fiber, the wood pulp is gradually reduced, which restricts the growth and development of cellulose fiber. However, bamboos that are widely grown in the subtropical zone have less development and utilization, and bamboo has better toughness and strength than trees. This has led to the idea of ​​“making bamboo with bamboo and bamboo for wood†to produce pulp, and then producing fiber. . The distribution of bamboo in China is very extensive, and it will become a bamboo when it is planted. Due to the abundant source of raw materials and low production cost, the use of bamboo as raw material for the development of bamboo fiber and related products has a very wide application prospect and practical value. In this issue, we will introduce bamboo pulp fiber, bamboo fiber and bamboo charcoal, which are produced from bamboo.
At present, with the development of science and technology and the change of people's consumption concept, the development of textile fibers and fabrics presents a different trend from the past: textile fabrics using new fibers have become fashionable products, and fabrics with a variety of fiber blends have become more and more popular. The more important the status, the environmentally-friendly textile fabrics are booming.
The fiber which is processed by the wet process using natural evergreen bamboo as the fiber pulp raw material is called bamboo pulp fiber. Since the bamboo pulp fiber basically maintains the natural characteristics of the bamboo fiber, its cross section is covered with irregular voids, which can absorb and evaporate water instantaneously, and has excellent gas permeability, moisture permeability capillary effect and high natural antibacterial rate. is widely used. SOFTBAMBOO is a registered trademark of bamboo pulp fiber of Shanghai Zhongfang Property Development Co., Ltd. After nearly three years of research and development, it has gradually created its own intellectual property and its own product style. Application of Bamboo Pulp Fiber in the Development of Characteristic Fabrics
The most superior performance of knitted fabrics made from bamboo fiber for knitted fabrics is cool, smooth, hygroscopic, easy to dry, good in gloss and natural bacteriostatic effect, so it is especially suitable for personal use. Purely spun bamboo fiber yarn or blended bamboo fiber yarn can be used. The most prominent problem of bamboo fiber yarns is that the yarn has high brittleness and poor elasticity, which has a certain gap with the requirements of the knitting yarns which are desired for the knitting looping process, such as good bending resistance, elasticity and flexibility. Special attention should be paid to weaving and dyeing. After blending bamboo fiber with organic cotton, Tencel, Modal, etc., the strength can be increased by 100% or more. In the blending process, the uniformity of the blending of bamboo fiber with Tencel and Modal must be done to prevent chromatic aberration. Due to the smooth surface of the bamboo fiber, the yarn elasticity is poor, with brittleness, the knitting and weaving process must be adjusted accordingly to control the yarn feeding tension, and uniform, the coil length should not be too short, otherwise it is easy to break holes.
Home textile fabric bamboo fiber bedding has the characteristics of moisture absorption, softness, good luster, smooth and wearable, luxurious and elegant, and natural health care. The medium and thick bedding series of jacquard fabrics can be designed and produced by using medium and thick pure bamboo fiber yarns. You can also choose pure bamboo yarn to do the weft interweaving with pure bamboo or bamboo Cotton Yarn. With a density of 680×470 roots/10cm, this high-density and high-density bedding series combines the softness, comfort and high-grade performance of high-strength cotton combed yarns, as well as the softness, smoothness and excellent suction of fine bamboo yarn. Dehumidification performance, suitable for spring and summer bed products. Since the strength of bamboo fiber single fiber is slightly lower than that of conventional fiber, the yarn strength is relatively low. When weaving fine ultra-high density fabric, yarn breakage, hairiness winding, unclear opening and the like are easily generated, and yarn dyeing and pulp are increased. Difficulties in the production of yarns, wide-width and high-efficiency weaving. Therefore, weaving and dyeing processes are preferred. In addition, bamboo fiber has a high moisture regain rate, a large shrinkage rate, and dimensional stability can be strictly controlled.
The bamboo fiber towel and the product are made of bamboo fiber and cotton yarn as the hair, and the cotton yarn is used as the towel. Such a structural arrangement fully reflects the characteristics of the bamboo yarn, and increases the strength of the finished product. Since the bamboo fiber has better moisture absorption capacity than cotton, the moisture absorption and gas permeability of the towel and the product are more excellent. Before weaving, it is necessary to apply light pulp, properly affix hairiness, and improve the strength and wear resistance of bamboo yarn to reduce the rate of weaving. In the weaving process, because the bamboo fiber breaks more than cotton, the environmental requirements are strict, and the relative humidity of the workshop should be 70% to 75%, so that the pulp film of the bamboo fiber yarn is not sticky or brittle.

Polyester Draw Texturing Yarn Cationic is a new type of polyester product which is spun by dimethyl isophthalate with SO3Na into polyester. Its appearance is no different from that of ordinary Polyester Yarn. However, the ionic modified polyester filament not only improves the color absorption of the fiber greatly, but also reduces the crystallinity and makes the dye molecules permeable easily. The fibers are easy to dye, the absorptivity is improved, and the water-absorbing is also improved. This kind of fibers can not only ensure cationic dyeability, but also increase the micropore of the fibers, and improve the dyeing rate, air permeability and moisture absorption of the fibers, the fabrics can be soft, air permeable, comfortable, antistatic and dyeable at room temperature and atmospheric pressure. Fabrics made of cationic yarn have the following characteristics when dyed with cationic dyestuff:
1. Bright tone, good deep dyeing;
2. High water-absorbing;
3. Good fastness to sunlight and fading;
4. Good stability in high temperature dyeing bath;
5. Dye stability is high when pH value changes in dyeing bath.
