Knitted fabrics are fabrics formed by bending yarns into loops and knitting with each other using knitting needles. The common production components are polyester, nylon, vinylon, spandex, cotton yarn, polypropylene, wool yarn and so on. There are many types of knitted fabrics on the market. Generally speaking, we will divide them into weft-knitted fabrics and warp-knitted fabrics according to their production process. They can also be classified according to their uses and production materials.
What is the composition of knitted fabrics
There are many production components of knitted fabrics, often using polyester, nylon, vinylon, spandex, cotton yarn, polypropylene, wool yarn, etc. as raw materials, and also woven from cotton, wool, silk, hemp, chemical fiber and its blended yarn as raw materials. Generally, it has good elasticity and extensibility. The fabric is soft, firm and wrinkle-resistant, has a strong hair feel, and is easy to wash and dry quickly. However, its hygroscopicity is poor, the fabric is not stiff enough, and it is easy to loosen and curl, and the chemical fiber fabric is easy to fluff, pilling, and hook silk.
What are the types of knitted fabrics
1. Classification according to usage
Knitted fabrics can be divided into underwear fabrics and outerwear fabrics according to their uses. Underwear fabrics are characterized by their fit, elasticity, comfort, easy movement, good flexibility, good moisture absorption and breathability, and good wrinkle resistance, but the fabric is easy to loosen, the dimensional stability is poor, and it is easy to hook and fluff. Varieties include weft plain needles, mesh fabrics, double ribs, single ribs, velvet, etc. The outer fabric is characterized by firmness and wear resistance, low shrinkage, easy washing and elasticity.
Second, according to the production process classification
1. Weft knitted fabric
The weft-knitted fabric is made of plain stitch, variable plain stitch, rib plain stitch, double rib plain stitch, jacquard, loop pile, etc. It is knitted on various weft knitting machines. It can use at least one yarn It can be formed, but in order to improve production efficiency, multiple yarns are generally used for weaving.
2. Warp knitted fabric
A warp knitted fabric cannot be formed with one yarn. It can be made by using multiple yarns to form loops along the longitudinal direction of the fabric at the same time, because one yarn can only form one loop. Lian Warp-knitted fabrics have the advantages of good vertical dimensional stability, firm structure, small looseness, no curling, and good air permeability, but their lateral extension, elasticity and softness are not as good as weft knitted fabrics.
3. Classification according to production materials
1. Polyester yarn-dyed knitted fabric
Polyester yarn-dyed knitted fabrics are made of dyed low-elastic polyester yarns, configured with different colors according to the design requirements, and weaved into a pattern of 3 to 6 colors or more with jacquard weave. Common patterns include stripes, lattices, flowers, figures, animals, landscapes, and geometric patterns. The fabric has bright color, beautiful appearance, harmonious colors, dense and thick texture, clear texture, strong hair type, and has a style similar to wool fabric tweed. Mainly used as men's and women's tops, suits, windbreakers, vests, skirts, padded jacket fabrics, children's clothing, etc.
2. Polyester knitted labor fabric
Polyester knitted labor fabric, also known as polyester knitted denim, is made of low-elastic polyester yarn, one of which is thicker dyed in navy blue, and the other is thinner, which is white silk, woven with jacquard weave, fabric surface In the navy blue, there are even and small natural color points. This kind of fabric is tight and thick, firm and wear-resistant, and firm and elastic. If the raw material uses core-spun yarn containing spandex, it can be knitted into elastic knitted denim with better elasticity. Mainly used as men's and women's tops and trousers.
3. Polyester knitted wick strip fabric
The polyester knitted wick strip fabric is made of low-elastic polyester yarn and is woven with varying double rib structures. During weaving, 1 to 2 stitches are drawn every several longitudinal rows of stitches, so that the cloth surface presents straight stripes with unequal width and unevenness. The thickness of the stripes can be determined according to requirements. This kind of fabric has distinct concave and convex, thick and full feel, good elasticity and warmth retention. Mainly used as fabrics for men's and women's tops, suits, windbreakers, children's clothing, etc.
4. Polyester covered cotton knitted fabric
Polyester covered cotton knitted fabric is a double rib composite polyester-cotton interwoven fabric. It uses polyester yarn to weave the front of the fabric and cotton yarn to weave the back of the fabric, and the front and back are connected by the tuck. The fabric is dyed to make shirts, jackets, sportswear fabrics. This kind of fabric is anti-wrinkle, firm and wear-resistant, moisture-absorbing and breathable on the side, soft and comfortable.
5. Artificial fur knitted fabric
Artificial fur knitted fabrics often use cotton yarn, viscose yarn or polypropylene yarn as the backing yarn, and acrylic or modified acrylic as fluff. When weaving, the fiber bundle and the ground yarn are looped together, and the two ends of the fiber are exposed on the surface of the fabric After weaving, we apply adhesive on the reverse side of the fabric to shape the fabric to avoid hair loss, and then through a series of post-finishing processes such as combing, printing and shearing to obtain artificial fur with multiple appearance effects. This fabric feels thick, soft and warm. According to different varieties, it is mainly used as coat fabric, clothing lining, collar, hat, etc. Artificial fur is also woven by warp knitting.
6. Velvet knitted fabric
Velvet knitted fabric is made of cotton yarn, polyester filament, nylon filament, polyester-cotton blended yarn and other raw materials as ground yarn, cotton yarn, polyester filament or polyester textured yarn, polyester-cotton blended yarn as raising yarn, and terry The ground yarn woven on the high-pile knitting machine forms the ground tissue. The pile yarns form loops, which are then looped to form the piles on the surface of the fabric, which are then trimmed after cutting and scalding. The pile yarn can also be knitted into the ground structure according to the pad yarn and formed by cutting the loop. This fabric has a soft hand feel, thick fabric, strong wear resistance, dense pile of hair, soft color. Mainly used as outer fabric, collar or hat materials. Swan knitted fabric is a kind of plush knitted fabric. In addition to weft knitting, the plush knitted fabrics can also be woven using warp knitting methods, for example, warp knitting pile shearing fabrics.
7. Hong Kong knitted woolen cloth
Hong Kong-type knitted woolen fabric is weft knitted woolen fabric made of high-grade cashmere and polyester yarn. It has the slippery, soft and bulky feel of cashmere fabric, and the soft gloss of silk fabric, good drape, non-shrinkage and strong breathability. Mainly used as fabric for spring, autumn and winter fashion.
