First of all, Tencel and Modal are both wood pulp fibers, so their performance characteristics are very similar.

Modal of Austrian blue crystal company is beech wood of 10 year.

Tencel is mainly made of conifers with high lignin fiber content.

2. The spinning principle is different.

Modal's viscose wet spinning process will use a lot of chemicals such as caustic soda, sulfuric acid, sulfur dioxide and zinc sulfate to alkalize, age, dissolve, yellow and filter wood pulp raw materials.

Tencel adopts a more environmentally-friendly solvent production process. The wood pulp mainly composed of coniferous trees and organic amine oxide solvent are mixed and heated until it is completely dissolved, and no derivatives and chemical reactions are generated during the dissolution process. Then, the impurities are removed and spun, so the whole process is more environmentally-friendly and does not pollute the ecology.

This process is particularly complicated. Viscose is 1 generation wood pulp fiber, modal is the second generation wood pulp fiber, and Tencel is the third generation wood pulp fiber. In fact, that's how it happened.

3. Different fiber characteristics.

The inner and outer layers of modal fiber are relatively uniform, and the sheath-core structure of fiber cross section is not as obvious as that of ordinary viscose fiber. The cross section tends to be round or waist-round, the longitudinal direction is smooth, the wet strength and modulus are high, and the moisture absorption performance is excellent.

The morphological structure of Lyocell fiber is completely different from that of ordinary viscose fiber, with uniform cross-sectional structure, round shape, no skin and core layer, smooth longitudinal surface and no grooves, and its mechanical properties are better than viscose fiber.

Characteristics of bamboo fiber fabric

The raw material of bamboo fiber yarn is high-quality bamboo fiber from southern Shan Ye, and the staple fiber yarn produced with bamboo pulp fiber is a green product. Knitted fabrics and garments made of cotton yarn made of this raw material have unique styles which are obviously different from cotton and lignocellulose fibers: wear resistance, pilling, high moisture absorption and quick drying, high air permeability and drape, and smooth hand feel. The blended fabric woven with this yarn makes cotton fibers softer and improves the appearance of the fabric.

Modal can also reflect its weaveability in the weaving process of woven fabrics, and can also be interwoven with yarns of other fibers to weave various fabrics. Modal products have broad development prospects in modern clothing.

Modal fiber mainly has the following main characteristics:

1 Modal fiber comes from natural wood and can be degraded naturally after use.

2.2 fineness. Modal fiber is 1dtex, cotton fiber is1.5 "2.5tex, and silk is1.3dtex.

3. Modal fiber is soft, smooth, bright in color, particularly smooth to the touch, bright in luster, better in drape than existing cotton, polyester and rayon, and has silky luster and feel, so it is a natural mercerized fabric.

4. Modal fiber has the strength and toughness of synthetic fiber, with dry strength of 35.6cn and wet strength of 25.3cn, which is higher than pure cotton and polyester cotton, thus reducing the phenomenon of broken ends in processing.

5. The moisture absorption capacity of modal fiber is 50% higher than that of cotton fiber, which makes modal fiber fabric dry and breathable. It is an ideal close-fitting fabric and health-care clothing product, which is beneficial to the victorious circulation and health of human body.

6. Compared with cotton fiber, modal fiber has good shape and dimensional stability, which makes the fabric have natural wrinkle resistance and non-ironing, making it more convenient and natural to wear.

7. Modal fiber has good dyeing performance, and it is as bright as new after repeated washing, with thorough moisture absorption and good color fastness. Compared with pure cotton, modal fiber is more comfortable to wear, and there is no disadvantage that pure cotton clothes are easy to fade and yellow.

Therefore, the fabric has bright colors and stable wearability. After washing cotton fabric for 25 times, it will feel harder and harder. Modal fiber fabric is softer and not greasy, silky and soft, mildew-proof, moth-proof, antibacterial, cool and comfortable to wear, and has the effect of beauty and skin care.

Excellent dyeing performance, bright luster, good natural antibacterial effect, environmental protection, in line with the trend of modern people pursuing health and comfort.

In particular, the specific blending of bamboo fiber and other fibers can not only reflect the performance of other fibers, but also give full play to the characteristics of bamboo fiber, bringing new characteristics to knitted fabrics.

Pure yarn and blended yarn (blended with Tencel, modal, sweat-wicking polyester, negative oxygen ion polyester, corn fiber, cotton, acrylic fiber, etc.). ) is the first choice for knitted close-fitting textiles. In terms of fashion, bamboo fiber fabrics have a better wearing effect in spring and summer.
