[Knitting common sense] Performance characteristics of knitted fabrics formed by various fibers
Business News November 13th, various textile fibers (such as natural fibers - such as cotton, wool, hemp fiber; rayon - such as viscose fiber, acetate fiber, etc.; synthetic fiber - nylon , polyester , polypropylene, acrylic, etc. ) All yarns can be used to weave knitted fabrics . The properties of the various fibers directly affect the fabric properties of the fabrics, and the use of blended yarns to interweave different fiber yarns can improve the performance of the fabric. Textile raw materials include natural fibers (cotton, wool, silk, hemp), rayon ( viscose fiber, acetate fiber) and various synthetic fibers (nylon, polyester, acrylic, polypropylene) and other yarns (yarn is twisted by fiber) And formed; the line is made up of two or more yarns and twisted) can be used to produce knitted fabrics. The performance of various fibers directly affects the performance of the knitted fabrics they form, but the use of blended yarns or interlacing of different fiber yarns is an important way to improve fabric performance. First, cotton knitted fabric Pure cotton knit fabric has excellent properties such as good moisture absorption, heat resistance, water wash resistance, alkali resistance and good skin feel. It is a good material for sewing all kinds of underwear, baby clothes, casual clothes, sportswear and summer outerwear. Cotton knit outerwear generally uses high-grade raw cotton with long fibers, and singeing and anti-shrinking finishing of yarn or grey fabric to improve gloss and stiffness. In addition, it is widely used in blending or interlacing with fibers such as hemp, acrylic, cotton, polyester, and viscose. The silk cover cotton (commonly known as polyester cover cotton) knitted fabric that has been popular in the market is made of polyester yarn on the surface (polyester filament is often used for single-sided silk cover cotton, polyester low-elastic yarn is often used for double-sided silk cover cotton). It is interwoven with pure cotton yarn . It not only has the excellent properties of pure cotton products such as breathability and moisture absorption, but also has the characteristics of beautiful gloss, anti-wrinkle, no scalding, quick-drying, and crispness. It is widely used to sew sportswear and coat. In the current trend of “returning to natureâ€, pure cotton knitwear products are favored, especially the high-quality “Joesa†fabrics that are woven with singeed and mercerized (ie, beaded mesh fabrics, abroad). Also known as PK cloth), it is more suitable for sewing summer coats and fashion. Second, silk knit silk Silk (mulberry silk) knitted silk has the characteristics of lightness, smoothness, elasticity, moisture absorption, good appearance, comfortable wearing, antibacterial and health care, and has better elasticity and tamper resistance than woven silk. Washing resistance, so more and more consumers are favored, silk fiber is known as the "fibre queen", is one of the best raw materials for sewing high-end clothing. Especially in recent years, the continuous application and development of new equipment, new processes and new products have led to the expansion of silk (mulberry silk) knitted fabrics from adapting to the production of underwear to the outerwear fashion, which is very popular in the domestic and foreign markets. However, in the textile production and processing of silk, the conditions are very strict, and most of them are softly processed (ie, treated by foaming) before they can be woven on the machine. Third, wool knitted products Wool knitting products made of wool or special animal hair are soft to the touch, good in wrinkle resistance, elasticity, warmth and moisture absorption, acid and alkali resistant, easy to "felt" in lye, easy to worm. Wool yarns or yarns are mostly used for forming or semi-formed weaving (such as woolen sweaters), and weaving of "José" fabrics with wool and acrylic or polyester blended yarns to sew outerwear or gloves. Nowadays, on the knitting circular machine, the knitted fabric made of wool and polyester blend is light in weight, good in recovery and good in fastness, easy to wash, quick-drying and stable in size, but the hand feels no smoothness of pure wool products. Fourth, hemp knitting products There are many types of hemp, but the main products used for knitting are ramie and flax. Hemp knitwear has a cool touch, good moisture absorption, and is four times stronger than wool. The wet strength is 70% higher than when dry. The knitted fabric woven from ramie fiber has the characteristics of quick moisture absorption, good gloss, good coolness and breathability, and is suitable for making summer clothes and bed sheets. Hemp knitwear has poor resistance to smudging and abrasion. The surface of the fabric is more plush. If it is clothing, it needs to be singeed and mercerized to reduce the feeling of itching on the skin. Hemp fiber used to be less used in China's knitting industry in the past, but it has developed rapidly in recent years. Through the research on the denaturation of hemp fiber, the application range has been expanded, the variety of colors and colors has been increasing, and in the production of knitting, hemp fiber is currently used. Products formed by blending or interlacing chemical fibers are also favored by consumers. Five, polyester knitwear Polyester woven knitted fabrics, the biggest feature is the crease resistance and shape retention, the fabric is crisp and wrinkle-free, dimensionally stable, easy to wash and dry, is beyond the reach of other fibers and chemical fiber fabrics. Another advantage is the strength. However, the moisture absorption of polyester must be poor, and the polyester fabric should not be close to the fire. In recent years, polyester fibers have been used in large quantities as raw materials for weft-knitted and warp- knitted fabrics. Nowadays, an ultra-fine polyester filament, which is 0.011 tex (0.1 denier) or less, is used in the market, and special-shaped spinning process is used to sew shaped fibers of various cross-section shapes, which have many excellent characteristics and are processed silk and imitation deer. The main raw material for leather knitwear. In particular, weft-knitted fabrics are used in a variety of polyester/cotton (T/C) blended yarns, and are used to weave fabrics such as plain weaves and fleece. . Sixth, acrylic knitted fabric Acrylic fiber is also the main raw material in the knitting industry. Therefore, the performance of the fiber is similar to that of wool. It has the name of “all-in-one woolâ€. Its hand feels fluffy and soft, and its warmth performance is about 15% higher. It has good elasticity and good solar resistance, but its wear resistance is poor and moisture absorption is low. Therefore, it is not suitable for making knitwear that is often rubbed, such as socks and gloves. Seven, polypropylene knitted fabric Polypropylene, a polypropylene fiber, is currently the cheapest synthetic fiber. The fabric produced by polypropylene weaving has high strength and strong chemical resistance, but the dyeing performance is poor, the light resistance is poor, and it is not resistant to high temperature. After the fabric is exposed to sunlight, the strength is obviously reduced. Knitted by polypropylene filament weaving, the fabric has anti-hook and anti-pilling effect. At present, the knitting fabrics produced by the knitting enterprises using fine-denier polypropylene yarn (commonly known as "Montess") have good moisture permeability and smoothness. After sweating, they will automatically send the sweat to the outer surface of the garment and disperse. The fabric feels fine, soft, drape, light and elegant. Eight, nylon knitwear Nylon fiber has good strength and moisture retention, best wear resistance, acid resistance, alkali resistance, insect resistance, good dyeability, and thermoplasticity, which can be used for permanent deformation processing. Elastic nylon yarns are commonly used in circular weft knitting machines, flat knitting machines or warp knitting machines to prepare a variety of sportswear, swimwear, nylon stretch shirts or outerwear fabrics. Nine, new fiber knitted fabric With the advancement of science and technology, the new fiber has been continuously introduced and the modified deformation treatment of existing textile raw materials has promoted the advancement of spinning technology. Many new raw materials have emerged, which has provided a great space for the production of knitted fabrics. The knitted fabric produced by the new fiber not only has a unique style, but also has the advantages of comfort, health care, functionality, etc., as well as perspiration, moisture absorption, etc., and is a product with great market potential.
