What are the knitted fabrics

Knitting is divided into weft knitted fabric and warp knitted fabric

(1) Weft knitted fabrics often use low-elastic polyester yarn or special-shaped polyester yarn, nylon yarn, cotton yarn, wool yarn, etc. as raw materials, using plain stitch, variable plain stitch, ribbed plain stitch, double ribbed plain stitch, jacquard Weaves, terry weaves, etc. are woven on various weft knitting machines. It has many varieties, generally has good elasticity and extensibility, the fabric is soft, firm and wrinkle-resistant, has a strong hair style, and is easy to wash and dry. However, its hygroscopicity is poor, the fabric is not stiff enough, and it is easy to fall off and curl, and the chemical fiber fabric is easy to fuzz, pilling and hooking. There are mainly the following varieties:

　　1. Polyester yarn-dyed knitted fabric: The fabric is bright in color, beautiful, with matching colors, tight and thick texture, clear weaves, and strong sense of wool, similar to wool fabric tweed style. Mainly used for men's and women's tops, suits, windbreakers, vests, skirts, cotton-padded jacket fabrics, children's clothing, etc.;

　　2. Polyester knitted labor fabric: This kind of fabric is tight and thick, strong and wear-resistant, firm and elastic. If the raw material is core-spun yarn containing spandex, it can be woven into elastic knitted denim with better elasticity. Trousers mainly used for men's and women's tops;

　　3. Polyester knitted wick strip fabric: The fabric has distinct unevenness, thick and plump hand feel, good elasticity and warmth retention. Mainly used for men's and women's tops, suits, windbreakers, children's clothing and other fabrics;

　　4. Polyester cover cotton knitted fabric: The fabric is dyed to make shirts, jackets, and sportswear fabrics. The fabric is stiff and wrinkle-resistant, strong and wear-resistant, moisture-absorbing and breathable on the body side, soft and comfortable;

　　 5. Artificial fur stitch fabric: The fabric has a thick hand feel, soft, and good warmth retention. Depending on the variety, it is mainly used for coat fabrics, clothing linings, collars, hats, etc. Artificial fur is also woven by warp knitting.

　　6. Velvet knitted fabric: The fabric feels soft, thick, strong and wear-resistant, with dense piles and soft color. Mainly used as outerwear fabrics, collars or hat materials, etc. It can also be made by warp knitting, for example: warp knitted looped pile fabric;

　　7. Hong Kong-style knitted woolen cloth: It not only has the smooth, soft, and bulky feel of cashmere fabric, but also has the characteristics of soft luster of silk fabric, good drape, no shrinkage, and air permeability. Mainly used as spring, autumn and winter fashion fabrics. (2) Warp knitted fabrics often use polyester, nylon, vinylon, polypropylene and other synthetic filaments as raw materials, but also use cotton, wool, silk, hemp, chemical fiber and their blended yarns as raw materials. It has the advantages of good longitudinal dimensional stability, stiff fabric, low dispersibility, no curling, and good air permeability. But its lateral extension, elasticity and softness are not as good as weft knitted fabrics. There are mainly the following types:

　　 1. Polyester warp-knitted fabric: The fabric is flat, bright in color, and can be divided into thick and thin. The thin type is mainly used as shirt and skirt fabric; the medium and thick type can be used as men's and women's clothing, windbreaker, tops, suits, trousers and other fabrics;

　　2. Warp-knitted pile fabric: mainly used as winter coats, windbreakers, tops, trousers and other fabrics. The fabric has good drape, easy to wash, quick-drying, and non-ironing, but static electricity accumulates during use and is easy to absorb dust;

　　3. Warp-knitted mesh fabric: The mesh fabric is light and thin, has good elasticity and air permeability, and feels smooth and soft. It is mainly used as summer shirt fabric for men and women;

　　4. Warp-knitted velvet fabric: The surface is densely fluffy, and it feels thick, plump, soft, flexible, and has good warmth retention. It is mainly used as winter clothing and children's clothing fabrics;

5. Warp-knitted loop fabric: this kind of fabric has full and thick hand feeling, firm and thick cloth body, good elasticity, moisture absorption, good warmth retention, stable loop structure, and good wearing performance. It is mainly used for sportswear and lapel T-shirts. , Pajamas, children's clothing and other fabrics.

　　The difference between warp knitting and weft knitting

　　Answer: Knitting can be divided into warp knitting and weft knitting

　　Multiple yarns for warp knitting are simultaneously formed into loops in the longitudinal direction (warp direction) of the cloth surface

　　Weft knitting uses one or more yarns to form loops in the transverse direction (weft) of the cloth.

Weft knitted fabrics can be formed with at least one yarn, but in order to improve production efficiency, multiple yarns are generally used for knitting; while warp knitted fabrics can not be formed with one yarn, one yarn It can only form a Lian-like object consisting of a coil.

　　All weft-knitted fabrics can be broken into threads in the opposite knitting direction, but warp-knitted fabrics cannot.

　　 Warp knitted fabrics cannot be knitted by hand.

　　 warp knitted fabrics are divided into two categories:

　　 One is Raschel fabric, the main feature is large flower shape, rough cloth surface, many holes, mainly used as decorative fabric;

　　 The second is tricol fabric, with fine cloth surface, few patterns, but high output. It is mainly used for covering fabrics and printed fabrics. This type of fabric is mostly used for chemical fiber filaments, otherwise the production efficiency is extremely low.

　　Clothing design considerations

　　一. Utilize the stretchability of knitted fabrics

　　 knitted fabrics have good stretchability, and can minimize the seams, gathers, splicing, etc. designed for styling in the template design. Secondly, knitted fabrics are generally not suitable to use the techniques of return and exfoliation, but to use the elasticity of the fabric itself or the appropriate use of folds to fit the curve of the human body. Then the elasticity of the fabric becomes an important basis in the design and production of the model.

The model of woven clothing is generally larger than the area required to wrap the human body, that is, there is a certain amount of looseness relative to the human body; while knitted clothing depends on the fabric structure used, if the fabric with particularly large elasticity (and the use of The yarn is related to the organizational structure.) Not only does it leave no looseness when designing the template, its sample size can be the same as the human girth size, or it can be reduced in consideration of the coefficient of elasticity.

　　 2. Utilize the curling properties of knitted fabrics

　　The curling of knitted fabrics is the phenomenon of edge fabric wrapping due to the disappearance of the stress in the edge loops of the fabric. Hemming is the shortcoming of knitted fabrics. It can cause uneven seams of garment pieces or size changes of garment edges, and ultimately affect the overall shape of the garment and the size of the garment. But not all knitted fabrics have hemming properties, but only fabrics with individual weaves such as weft jerseys. For this kind of fabric, you can pull the edges and insert ribs by adding sizes when designing the pattern. Or piping and inlaid adhesive interlining strips on the edge of the garment. The hemming of some knitted fabrics has been eliminated during the finishing process of the fabric, which avoids the trouble of template design.

It needs to be pointed out that many designers can use the fabric's curling properties to design them on the neckline and cuffs of the model based on the understanding of the properties of the fabric, so that the clothing has a special appearance style, which is refreshing. , Especially in the knitting of shaped clothing, it can also use its curling to form a unique pattern or dividing line.

　　 Three, pay attention to the dispersibility of knitted fabrics

　　 knitted fabrics are different from woven fabrics in style and characteristics. The style of clothing should not only emphasize the advantages of the fabric, but also overcome its shortcomings. Because individual knitted fabrics are dispersible, please pay attention to some knitted fabrics not to use too much exaggeration when designing and making patterns. Try not to design roads and cutting lines as much as possible. The stitching should not be too many to prevent the occurrence of knitting loops. It will affect the wearability of the clothing, and the simple and soft lines should be used in harmony with the soft and fit style of knitwear.
