(1) Weft knitted fabrics are often made of low-elastic polyester yarn or special-shaped polyester yarn, nylon yarn, cotton yarn, wool yarn, etc. Tissue, terry tissue, etc., are knitted on various weft knitting machines. It has many varieties, generally has good elasticity and extensibility, the fabric is soft, firm and wrinkle-resistant, the hair type is strong, and it is easy to wash and dry quickly. However, its hygroscopicity is poor, the fabric is not stiff enough, and it is easy to fall off and curl. There are mainly the following varieties:

1. Polyester yarn-dyed knitted fabric: The fabric is bright in color, beautiful in color, harmonious in color matching, dense in texture, clear in texture, strong in wool shape, and has a tweed style similar to wool fabric. Mainly used for men's and women's tops, suits, windbreakers, vests, skirts, padded jacket fabrics, children's clothing, etc.;

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

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

4. Polyester-covered cotton knitted fabric: The fabric is dyed for shirts, jackets and sportswear. The fabric is stiff and wrinkle-resistant, firm and wear-resistant, moisture-absorbing and breathable on the body side, soft and comfortable;

5. Artificial fur needle fabric: The fabric feels thick, soft and warm. According to different varieties, it is mainly used for coat fabrics, clothing linings, collars, hats, etc. Artificial fur is also woven with warp knitting.

6. Velvet knitted fabric: The fabric feels soft, thick, firm and wear-resistant, with dense and towering fluff, and soft shade. Mainly used as outerwear fabric, collar or hat material, etc. It can also be made of warp knitting, for example: warp terry shearling fabric;

7. Hong Kong-type knitted woolen wool: It not only has the smooth, glutinous, soft and bulky feel of cashmere fabric, but also has the characteristics of soft luster, good drapability, non-shrinking and air permeability of silk fabric. Mainly used for spring, autumn and winter fashion fabrics.

(2) Warp knitted fabrics are often made of synthetic filaments such as polyester, nylon, vinylon, and polypropylene as raw materials, and are also woven from cotton, wool, silk, hemp, chemical fibers and their blended yarns. 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. There are mainly the following types:

1. Polyester warp knitted fabric: the fabric surface is flat and firm, the color is bright, and there are thick and thin types. The thin ones are mainly used as shirts and skirts; the medium and thick ones can be used for men's and women's clothing, windbreakers, tops, suits, trousers and other fabrics;

2. Warp knitted fleece fabric: mainly used for winter men's and women's coats, windbreakers, tops, trousers and other fabrics, the fabric has good drape, easy to wash, quick-dry, and no ironing, but static electricity accumulates during use, and it is easy to absorb dust;

3. Warp knitted mesh fabric: The texture of mesh fabric is light and thin, with good elasticity and breathability, and it feels smooth and soft. It is mainly used as a summer shirt fabric for men and women;

4. Warp knitted velvet fabric: the surface fluff is dense and standing, the hand feels thick, plump, soft, elastic, and has good heat retention. It is mainly used for winter clothing and children's clothing fabrics;

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

What is the difference between warp knitting and weft knitting in knitted fabrics?

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

Warp knitting uses multiple yarns to form loops along the longitudinal (warp) direction of the fabric at the same time

Weft knitting uses one or more yarns to form loops in sequence in the transverse direction (weft) of a sector

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 cannot be formed with one yarn, one yarn Only a ligament of one coil can be formed.

All weft knitted fabrics can be detached into threads in the reverse knitting direction, but warp knitted fabrics cannot.

Warp knitted fabrics cannot be knitted by hand.

There are two main categories of warp knitted fabrics:

One is Raschel fabric, which is mainly characterized by large flower shape, rough cloth surface and many holes, mainly used as decorative fabric;

The second is tricol fabric, which has a fine surface and few colors, but has a high output. It is mainly used for covering fabrics and printed fabrics. These fabrics are mostly used for chemical fiber filaments, otherwise the production efficiency is extremely low.

Precautions for clothing design using knitted fabrics:

1. Utilize the elasticity of knitted fabrics

Knitted fabrics have good stretchability, and can minimize seams, pleats, splices, etc. designed for styling in model design. Secondly, knitted fabrics are generally not suitable to use the techniques of pushing and ironing, but to use the elasticity of the fabric itself or the appropriate use of folds to fit the human body curve. Then the size of the fabric flexibility becomes an important basis for 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, it has a certain amount of looseness relative to the human body; and knitted clothing, depending on the structure of the fabric used, if the elastic fabric is particularly large (and the use of The yarn is related to the organizational structure) when designing the template, not only does not leave any looseness, but the size of the template can be the same as the circumference of the person, or the size of the template can be reduced by considering the elastic coefficient.

2. Utilize the curling properties of knitted fabrics

The hemming property of knitted fabrics is the phenomenon of edge fabric wrapping caused by the disappearance of stress in the edge loops of the fabric. Hemming is the downside of knitted fabrics. It can cause uneven seams of garment pieces or dimensional changes of garment edges, which ultimately affect the overall styling effect of garments and the specifications and dimensions of garments. However, not all knitted fabrics have hemming properties, but only fabrics with individual structure such as weft jersey fabrics. For this kind of fabric, it can be added to the size for hemming and rib stitching when designing the template. Or piping and inlaying adhesive strips at the edge of the garment. The curling of some knitted fabrics has been eliminated in the process of finishing the fabric, avoiding the trouble of template design.

It should be pointed out that many designers can turn the disadvantages into advantages on the basis of understanding the properties of the fabrics, and use the curling properties of the fabrics to design them on the neckline and cuffs of the model, so that the clothing has a special appearance style, which is refreshing. , especially in the weaving of shaped garments, it can also use its curling properties to form unique patterns or dividing lines.

3. Pay attention to the dispersibility of knitted fabrics

Knitted fabrics are different from woven fabrics in style and characteristics, and the style of their clothing should not only emphasize the advantages of fabrics, but also overcome their shortcomings. Because individual knitted fabrics are detachable, it should be noted that some knitted fabrics should not use too much exaggeration during the design and production of the sample, and try not to design darts, cutting lines, and splicing seams should not be too much to prevent knitting loops. The detachment of the clothing will affect the wearability of the clothing. Simple and soft lines should be used in harmony with the soft and fit style of the knitwear.
