What kind of fabric is knitted fabric? What are the advantages and disadvantages of knitted fabrics?
The delicate softness and elegance of knitted fabrics are deeply loved by professionals in the fashion circle. Its characteristics that are suitable for all seasons also make it visible in wardrobes. So what exactly is knitted fabric?
Knitted fabric is a fabric formed by using knitting needles to form yarns of various raw materials and varieties into coils and then connecting them through strings. Knitting is divided into warp knitting and weft knitting. Warp knitting uses multiple yarns to form loops simultaneously along the longitudinal direction (warp direction) of the cloth surface; while weft knitting uses one or more yarns sequentially along the transverse direction (weft direction) of the cloth surface. Looping, the raw materials are mainly natural fibers such as cotton, linen, silk, wool, etc., as well as chemical fibers such as polyester and polyester.
Warp knitting often uses polyester, nylon, vinylon, polypropylene and other synthetic filaments as raw materials. It can also be woven with cotton, wool, silk, linen, chemical fiber and their blended yarns as raw materials. It has the advantages of good longitudinal dimensional stability, stiff fabric, small detachment, no curling, and good air permeability. However, its lateral extension, elasticity and softness are not as good as weft knitted fabrics.
Weft knitting is often made of low-elastic polyester yarn or special-shaped polyester yarn, nylon yarn, cotton yarn, wool yarn, etc. as raw materials and is knitted on various weft knitting machines. It has many varieties and generally has good elasticity and extensibility. The fabric is soft, strong and wrinkle-resistant, has a strong wool texture and is easy to wash and dry quickly. However, its hygroscopicity is poor, the fabric is not stiff enough, and it is easy to fall apart and curl. Chemical fiber fabrics are easy to fluff, pill, and snag.
Advantages of knitted fabrics:
1. Stretchability: Knitted clothing is made of yarns that are bent into loops and strung together. The loops have a large room for expansion up and down, left and right, so they have good elasticity. They fit the body when worn, are comfortable, convenient, and suitable. Requirements such as stretching and bending during human movement.
2. Softness: The raw materials used in knitted clothing fabrics are fluffy and soft yarns. The surface of the fabric has a layer of tiny suede. In addition, the tissue composed of coils is loose and porous, which reduces the friction between the skin and the surface of the fabric when worn. , giving people a comfortable and gentle feeling.
3. Hygroscopicity and breathability: Because the coils that make up the knitted fabric are intertwined with each other, countless isolated air pockets are formed inside the fabric, which has good warmth retention and breathability.
4. Anti-wrinkle: When the knitted fabric is subjected to wrinkle external force, the coils can be transferred to adapt to the deformation when the force is applied; when the wrinkle force disappears, the transferred yarn can quickly return to its original state.
Disadvantages of knitted fabrics:
1. Easy to come apart: When the yarn on the knitted fabric breaks or the coils lose their connection, causing the coils to separate, the coils will come apart longitudinally, affecting the appearance and size of the fabric.
2. Poor stability: Except for chemical fiber knitted products, other knitted products have varying degrees of shrinkage and are prone to snagging and pilling: due to the loose structure of knitted fabrics, the fibers on the fabrics are easily damaged during processing and use. The sharp and hard objects hook out to form silk loops. At the same time, the fibers are often fluffed due to wear.
Summarize:
Knitted fabrics can be made from a wide range of raw materials, including cotton, wool, silk, linen, chemical fibers and their blended yarns or combined yarns. Knitted fabrics have a soft texture. In addition to good wrinkle resistance and breathability, they also have greater extensibility and elasticity. They are suitable for making underwear, tights, sportswear, etc. After changing the structure and improving dimensional stability, knitted fabrics can also be used as outerwear, mattresses, etc.
Knitted fabrics can be woven into gray cloth first, and then cut and sewn into various knitted products; they can also be directly woven into fully formed or partially formed products, such as socks, gloves, etc. In addition to being used as underwear, outerwear, socks, gloves, hats, sheets, bedspreads, curtains, mosquito nets, carpets, lace and other clothing, living and decorative fabrics, knitted fabrics are also widely used in industry, agriculture and medical and health fields.
