Popular Science | Characteristics of Modal, Tencel and Bamboo Fiber Fabrics

Tencel It is a purely natural regenerated fiber developed by the British company Acordis using 100% natural wood pulp extracted from eucalyptus trees. It is called the “fiber dream of the 21st century”. Its characteristics: softer feel than silk; better hygroscopicity than cotton; light, easy to wash and dry.

“Tencel” is the Chinese transliteration of the English word “Tencel”, but in Chinese newspapers and periodicals In magazines, people are usually referred to as “tence” directly. Tencel is a new creature. The word Tencel is not included in the 1993 edition of “New English-Chinese Dictionary” (supplementary edition) by Shanghai Translation Publishing House and the 1995 edition of “English-Chinese Textile Industry Vocabulary” (continued edition) by China Textile Publishing House. Internationally, the popularity of Tencel began in the early 1990s, while domestic development of Tencel began in the second half of the 1990s, and it became popular in the domestic market at the end of the 1990s.

Tencel is a product of Iyocell fiber (Iyocell is a fiber produced by organic solvent spinning method Plain fiber, its genus name is determined by the International Bureau of Standards for Man-made and Synthetic Fibers). Tencel is made from English baked pottery (Courtualds) company produced and patented. Therefore, only the Iyocell fiber produced by Ceramics Co., Ltd. can be called Tencel. Similarly, only products containing Tencel approved by this company can use the name Tencel or carry a Tencel hangtag.

Tencel has high strength and can be used as an industrial fiber. It also has the comfort and comfort of cotton. Silk-like feel and good drape. It is currently the only new fiber in the world that combines the advantages of synthetic fibers and natural fibers. As soon as Tencel appeared, it attracted countless fabric merchants and clothing manufacturers who paid attention to the development of new fabrics, and it became a fiber name that has been used very frequently recently. Tencel causes very little pollution to the environment during the production process, so it is also known as the “green fiber of the 21st century.”

Currently Tencel has the following specifications:
Fineness: 1.4dex, 1.7dex, 2.4dex, 3.3dex
Average length: 38mm 51mm (suitable for cotton spinning, medium-length spinning) 60mm 80mm (suitable for wool spinning system)
Tencel has two models: one is the standard type (G100) It is fibrillated Tencel, and the other type is A100, which is called non-fibrillated Tencel.

Silk-like feel and Good drape. It is currently the only new fiber in the world that combines the advantages of synthetic fibers and natural fibers. As soon as Tencel appeared, it attracted countless fabric merchants and clothing manufacturers who paid attention to the development of new fabrics, and it became a fiber name that has been used very frequently recently. Tencel causes very little pollution to the environment during the production process, so it is also known as the “green fiber of the 21st century.”

The raw material of Modal fiber is produced in the shrub forests of Europe. It is made into thumb slurry and then processed through a special spinning process. It is a Cellulose fiber, so it is a cellulose fiber like cotton and is a pure natural fiber.

Modal products are now mostly used in the production of underwear because of their good softness and excellent hygroscopicity but poor fabric stiffness. Modal knitted fabrics are mainly used to make underwear. However, modal has the characteristics of silvery luster, excellent dyeability and bright color after dyeing, which are enough to make it suitable for outerwear. Because of this, modal is increasingly becoming a material for outerwear and decorative fabrics.

In order to improve the shortcomings of poor stiffness of Modal products, Modal can be combined with other Fibers are blended and can achieve very good results. JM/C(50/50) can make up for this shortcoming. The more you wash it, the brighter it becomes.

The strength of Modal is close to the strength of polyester (35cn/tec), and the wet strength is slightly lower than Cotton is soft and smooth, with a silky feel. The wet elongation is small. The dry elongation of the fiber is between cotton and viscose. Its wet elongation is similar to cotton, but smaller than viscose; washing shrinkage rate lower, its goodThe moisture-retaining capacity is 50% higher than that of cotton, and it absorbs moisture very quickly. The dyeing characteristics of modal fiber are that it absorbs pigments faster than combed cotton and has a high absorption rate. The color is bright after dyeing and has good breathability.

Fine-denier Modal fiber meets the requirements of ECO-TEX standards, is physiologically harmless and Biodegradable. It has special advantages for textiles that are in direct contact with the body, and the fine denier fiber gives knitted fabrics comfortable wearing properties, soft hand feel, flowing drape, attractive luster and high moisture absorption.

Because of this, many warp knitting and weft knitting manufacturers have The fiber began to be used as raw material to produce daywear and pajamas, sportswear and casual wear, and was also used in lace. Calcium fabric has a particularly ideal effect when used with close-fitting clothing, allowing your skin to always feel dry and comfortable. Even after washing, it can still maintain a water-absorbent and light and soft feeling. This is all due to the smooth surface of the material. The surface prevents the fibers from tangling with each other during the cleaning process.

The raw material of bamboo fiber yarn is selected from the high-quality mountain and wild moso bamboo fiber in the south , short-thread yarn produced using bamboo pulp fiber, is a green product. Knitted fabrics and clothing produced from cotton yarn made from this raw material have unique styles that are obviously different from cotton and wood-based cellulose fibers: wear resistance, lint-free Balls, high moisture absorption, quick drying, high breathability, good drape, and smooth feel. The blended fabric woven with this yarn makes the cotton fiber more supple and improves the appearance of the fabric.

Modal can also reflect its weavability during the weaving process of woven fabrics, and can also be combined with other fibers Yarns are interwoven to form a variety of fabrics. Modal products have broad development prospects in modern clothing.

Modal fiber mainly has the following main characteristics:
1. The raw material of Modal fiber comes from natural wood and can be naturally degraded after use.
2.Modal The fiber fineness is 1dtex, while the cotton fiber fineness is 1.5” 2.5tex and the silk fineness is 1.3dtex.
3. Modal fiber is soft, smooth, bright in color, the fabric feels particularly smooth, the cloth surface is bright, and the drape is better than the existing ones Made of cotton, polyester and rayon, it has a silky luster and feel. It is a natural mercerized fabric.
4. Modal fiber has the strength and toughness of synthetic fibers, with dry strength 35.6cn and wet strength 25.3cn. Stronger than pure cotton , polyester-cotton, reducing breakage during processing
5. The moisture absorption capacity of Modal fiber is 50% higher than that of cotton fiber, which allows Modal fiber fabric to stay dry and breathable. It is an ideal close-fitting fabric and health-care clothing product, which is beneficial to the human body. Victory loop and health
6. Compared with cotton fiber, Modal fiber has good shape and dimensional stability. The fabric has natural wrinkle resistance and non-ironing properties, making it more convenient and natural to wear.
7.Modal The fiber has good dyeing properties and remains as bright as new after many washes. It absorbs moisture thoroughly and has good color fastness. Compared with pure cotton, it is more comfortable to wear and does not have the shortcomings of pure cotton clothing such as fading and yellowing.

So the fabric colorThe fabric is bright and has stable wearing properties. After 25 washes with cotton fabrics, the hand feel will become harder with each wash. Modal fiber fabric is just the opposite. The more you wash it, the softer it becomes. It is greasy, plump, silky soft, mildew-proof, moth-proof and antibacterial, cool and comfortable to wear, and has the effect of beauty and skin care. It has excellent dyeing performance, bright luster, good natural antibacterial effect and environmental protection, and conforms to the trend of modern people pursuing health and comfort.

In particular, bamboo fiber is blended with other types of fibers in specific proportions, both It can reflect the performance of other fibers and give full play to the characteristics of bamboo fiber, bringing new characteristics to knitted fabrics. Pure and blended yarns (blended with different types and ratios of Tencel, Modal, sweat-wicking polyester, negative-ion polyester, corn fiber, cotton, acrylic and other fibers) are the preferred fabrics for knitted close-fitting textiles. In trendy fashion, bamboo fiber fabrics are more effective in spring and summer clothing.
