Knitted fabric type and related knitted fabric knowledge
(1) weft knitted fabrics are usually made of low-elastic polyester or hetero-polyester yarns, polyamide yarn, cotton yarn, wool yarn, etc., which are knitted on various weft knitting machines with plain stitch organization, variable plain stitch organization, rib plain stitch organization, double rib plain stitch organization, jacquard organization, terry organization, etc. Its breed is more, have good stretch of flexibility commonly, the fabric is soft, firm firm is resistant to wrinkle, wool feeling is stronger, and easy to listen to quickly dry. Nevertheless its hygroscopicity is poor, the fabric is not quite crisp, and easy to take off loose, roll edge, chemical fiber fabrics easy to wool, pilling, hook silk. There are mainly the following varieties:
1. Polyester yarn-dyed knitted fabric: the fabric has bright color, beautiful appearance, harmonious color matching, dense and thick texture, clear texture, strong wool shape, similar to wool fabric tweed style. Mainly used for men and women's wear, suit, windbreaker, vest, skirt, cotton-padded jacket fabric, children's wear;
2. Polyester knitted labor fabric: this fabric is compact and thick, firm and wear-resistant, crisp and elastic. If the core yarn containing spandex is used as the raw material, it can be woven into elastic knitted jeans with better elasticity. Trousers used chiefly for men's and women's coats;
3. Polyester knitted lamp-wick fabric: the fabric has distinct concave and convex shape, thick and plump feel, good elasticity and heat preservation. Mainly used for men's and women's wear, suit, windbreaker, children's wear and other fabrics;
4, polyester cover cotton knitted fabric: dyed shirt, jacket, sportswear fabric. The fabric is crisp and wrinkle-resistant, firm and wear-resistant, close to the skin and moisture-absorbing, soft and comfortable;
5. Faux fur needle fabric: the fabric feels thick, soft and warm. According to the variety, mainly used for coat fabric, clothing lining, collar, hat, etc. Artificial fur is also made by warp knitting.
6. Velvet knitted fabric: the fabric feels soft, thick and hard to wear, with dense hair and soft color. Mainly used as fabric, collar or hat material. It can also be woven with warp knitting, e.g.
7. Hong kong-style knitted wool: it has both the smooth and soft feel of cashmere fabric and the characteristics of soft luster, good drape, non-shrinkage and air permeability of silk fabric. Mainly used for spring, autumn and winter fashion fabrics.
Warp knitted fabrics are usually made of polyester, polyamide, vinylon, polypropylene and other synthetic filament fibers, as well as cotton, wool, silk, hemp, chemical fibers and their blended yarns. It has the advantages of good longitudinal dimension stability, crisp fabric, little looseness, no edging, good air permeability and so on. However, its lateral extension, elasticity and softness are not as good as those of weft knitted fabrics. There are mainly the following categories:
1. Polyester warp knitted fabric: the cloth is flat and straight, with bright color, thick and thin. Thin mainly used as shirt, skirt fabric; Medium and thick type, thick type can be used for men and women in clothing, windbreaker, jacket, suit, trousers and other fabrics;
2. Warp knitted pile fabric: it is mainly used as winter coat, windbreaker, jacket, trousers and other fabrics. The fabric has good drape, easy to wash, quick drying and permanent care.
3. Warp knitted mesh fabric: the fabric is light and thin, with good elasticity and air permeability. It feels smooth, cool and soft.
4. Warp-knitted velvet fabric: the surface of the fabric is thick and fluffy, with thick, plump, soft, elastic and good warmth preservation. It is mainly used for winter clothing and children's clothing.
5. Warp knitted terry fabric: this kind of fabric has full and thick feel, firm and thick body, good elasticity, moisture absorption and heat preservation, stable terry structure and good performance, mainly for sports clothes, lapel t-shirts, pajamas, children's wear and other fabrics.
What is the difference between warp knitting and weft knitting?
Answer: knitting can be divided into warp knitting and weft knitting
Warp knitting consists of multiple yarns looped simultaneously along the longitudinal (warp) direction of the fabric
Weft knitting consists of one or more yarns looped in a horizontal (weft) order along the department
Weft knitting can be formed with at least one yarn. However, in order to improve production efficiency, multiple yarns are usually used for knitting. Warp knitted fabrics, on the other hand, do not form from a single thread, but from a single coil.
All weft fabrics can be spun in the opposite direction, but warp knitted fabrics cannot.
Warp knitted fabrics cannot be knitted by hand.
Warp knitted fabrics fall into two broad categories:
One is Raschel fabric, which is mainly characterized by large flower shape, coarse cloth surface and many holes, mainly for decorative fabrics;
The second is tricol fabric, which has fine cloth cover, less color, but high yield. It is mainly used for covering fabric and printing fabric. This kind of fabric is mostly used for chemical filament, otherwise the production efficiency is very low
Points to note for garment design using knitted fabrics:
The use of knitted fabric scalability
Knitted fabric has good scalability, in the sample design can be **** limit to reduce the design for modeling seams, pleats, splicing, etc. Next, knit fabrics also shoulds not apply commonly push return, pull very hot technical modelling, use the flexibility of fabrics itself however or apply the processing of drape gimmick appropriately to suit human body curve. Then the size of fabric scalability becomes an important basis in the design and production of sample.
The example that tatting weaves dress finally and wrap the area that human body place needs to compare commonly a few bigger, have certain looseness to human body namely; However, according to the different fabric structure used in knitted garments, if the fabric with very large elasticity (related to the yarn and organization structure used) is not loose when designing the sample, the sample size can not only be the same as the size of people, but also be reduced by considering the elastic coefficient.
Second, the use of knitted fabric edge
The edging of knitted fabric is caused by the loss of the stress in the edging coil. Edging is a weakness of knitted fabrics. It can cause uneven seams or changes in the size of the garment edge, and ultimately affect the overall modeling effect of the garment and the size of the garment. However, not all knitted fabrics have edge curling, but individual fabric structures, such as weft flat knitted fabrics. For this kind of fabric, it can be solved by adding dimension to the edge, inserting rib or piping, and inlaying and binding linings at the garment edges. The edging of some knitted fabrics is eliminated during the finishing process, thus avoiding the trouble of pattern design.
It should be pointed out that many designers on the basis of understanding the fabric performance can be cons for profit, using the fabric edge, should be designed to the sample of the neckline, cuffs, which makes the appearance of the clothing get special style, refreshing, especially in the forming of clothing weaving can also use its edge to form a unique pattern or line.
Third, pay attention to the shedding of knitted fabrics
Knitted fabrics are different from woven fabrics in style and characteristics. The advantages of knitted fabrics should be emphasized and the disadvantages should be overcome. Due to individual knitting fabric has the decoherence, model design and production to pay attention to some knitted fabrics don't use too much exaggeration, as far as possible not provincial highway design, and cutting line, spell juncture is unfavorable and overmuch, in order to prevent the stich decoherence occurred and affect the serviceability of the clothing, should use concise soft line coordinated with fabric soft and comfortable body style.
