There are two main weaving methods, knitted and woven. Knitting refers to weaving in the form of loops and loops. The most intuitive feature of the fabric is that you cannot see the warp and weft directions of the fabric intersect perpendicularly, but one by one loop, and the knit fabric has a soft hand and a strong drape. Weaving means that the warp and weft of the fabric (that is, vertical and horizontal) are formed by vertical interweaving; woven fabrics are divided into shuttle woven and shuttleless woven, the difference is whether there is a Weft insertion effect of shuttle.
knitting
The process of using knitting needles to form loops of various raw materials and varieties of yarns, and then connecting them through knitting to form knitted fabrics. The knitted material is soft, has good wrinkle resistance and breath ability, and has large extensibility and elasticity, and is comfortable to wear. In addition to knitting and decoration, knitted products can also be used in the fields of industry and agriculture, as well as medical and health and national defense. There are two types of knitting: hand knitting and machine knitting. Hand-knitting uses stick needles. It has a long history, exquisite craftsmanship, and flexible flower shapes. It has been widely spread and developed in folk.
Woven
The process of forming woven fabric with yarn as warp and weft according to various fabric structures. It usually consists of three parts: preparation before weaving, weaving and weaving of the warp yarn into a weaving shaft and weft yarn into a shuttlecock (or package). Weaving is an important part of the production of the textile industry. It can be divided into cotton, wool, silk and linen according to the type of raw materials used. The variety and use of woven fabrics are extremely wide (see textiles). According to different requirements, select the appropriate yarn raw materials and appropriate fabric organization.
The difference between weaving and knitting
1. The fabric structure is different. Weaving can control different weft yarns passing through the warp yarns to form different fabric patterns and structures. Knitted fabric also has a corresponding organization structure, including the basic organization: flat needle organization, rib organization, and double back organization.
2. The organization of change is different. Weaving is formed by the combination of the above three basic organizational changes. In addition to the three basic organization changes of knitting, there are plain needle structure and rib structure as its basic changes.
3. The basic unit of fabric organization is different. The loop of a knitted fabric is the smallest basic unit of the knitted fabric, and the loop is composed of a trunk curve and an extension line in a spatial curve. Each point of intersection between the warp and weft of a woven fabric is called a weaving point, and is the smallest basic unit of a woven fabric.
4. Complex Chengdu is different. Weaving has double tissues (multiple woven into thick flannelettes, cotton fleece blankets, etc.), fluffed tissues (such as corduroy fabrics), towel tissues (towel fabrics), double-layer tissues (towel fabrics), and leno tissues. And knitting also has double back and so on. In general, Chengdu is more complex than weaving.
5. Features and uses are different. Woven fabrics are suitable for various printing and dyeing finishing methods. Generally speaking, printed and jacquard patterns are finer than knitted, knitted and felt fabrics. After changing the structure and improving the dimensional stability of knitted fabrics, it can also be used as underwear, outerwear, socks, gloves, hats, sheets, bedspreads, curtains, mosquito nets, carpets, lace and other clothing, living and decorative cloths.
The difference between knitted fabrics and woven fabrics
Knitted fabrics and woven fabrics have their own unique characteristics due to the different methods of weaving. In terms of processing technology, cloth surface structure, fabric characteristics, and finished product uses, they have their own unique characteristics. Here are some comparisons.
1. Composition of fabric structure:
(A) Knitted fabric: A yarn is sequentially bent into a loop, and the loops are connected in series to form a fabric. The process of forming a loop of yarn can be performed horizontally or longitudinally. Lateral weaving is called weft knitting and longitudinal weaving Called warp knitted fabric.
(B) Shuttle fabric: It is a fabric made of two or more sets of mutually perpendicular yarns interlaced at a 90-degree angle of warp and weft. The longitudinal yarns are called warp yarns and the transverse yarns are called weft yarns.
2. The basic unit of fabric organization:
(A) Knitted fabric: The loop is the smallest basic unit of knitted fabric, and the loop is composed of loop trunk and extension line in a spatial curve.
(B) Woven fabric: Each point of intersection between warp and weft yarns is called a weaving point and is the smallest basic unit of a woven fabric.
3. Fabric organization characteristics:
(A) Knitted fabric: because the loop is made by the yarn bending in space, and each loop is composed of a yarn, when the knitted fabric is subjected to external tension, such as longitudinal stretching, the bending of the loop changes, and the loop The height of the stitches also increases, while the width of the stitches decreases. If the tension is laterally stretched, the situation is the opposite. The height and width of the stitches can be switched between each other under different tension conditions, so the stretch ability of the knitted fabric is large.
(B) Woven fabric: Because the warp and weft are intertwined, and the bends in a direction perpendicular to the plane of the fabric, the degree of bending is related to the mutual tension between the warp and weft, and the stiffness of the yarn. External tension, such as longitudinal stretching, warp yarn tension increases, bending decreases, while weft yarn bending increases, such as longitudinal stretching non-stop until the warp yarns are fully straightened, while the fabric shrinks laterally. When the woven fabric is stretched laterally by external tension, the tension of the weft yarn increases, the bending decreases, and the warp warp increases, such as the horizontal stretching is continued until the weft yarn is completely straightened, and the fabric shrinks longitudinally. Warp and weft yarns do not change, unlike knitted fabrics.
4. Characteristics of fabric organization:
(A) Knitted fabric: It can be stretched in all directions and has good elasticity. Because the knitted fabric is formed by hole-shaped loops, it has a large air permeability and feels soft.
(B) Woven fabric: Due to the warp fabric warp, weft yarn extension and shrinkage have little relationship and no change occurs, so the fabric is generally tight and stiff.
5. The physical and mechanical properties of the fabric:
(A) Knitted fabric: the physical and mechanical properties of the fabric, including longitudinal density, transverse density, square meter weight, elongation, elasticity, breaking strength, abrasion resistance, curling, thickness, release, shrinkage, covering And bulk density.
(B) Woven fabric: The physical and mechanical properties of the woven fabric, including the yarn density of warp and weft yarns, selvedge, front and back, forward and reverse wool direction, and fabric coverage.

Black stockings are a type of stockings commonly worn by women, referred to as black silk, which is very sexy to wear. There are many black stockings on the market, including nylon silk, crystal silk, cored silk, velvet, Lycra, Teda, and so on. Stockings are very thin, so you must always pay attention to cleaning and maintenance methods. When cleaning, use neutral detergent in warm water and do not wring. Let ’s take a look with Shanghai Sock Show next.
What are the materials of black stockings
1. Ordinary nylon yarn: ordinary nylon silk stockings belong to the early products. The biggest drawbacks are poor elasticity, low transparency, and smoothness.
2. Crystal silk: In order to solve the defects of ordinary nylon silk, crystal silk is available. This material has greatly improved transparency, making stockings no longer rigid, but the disadvantage of poor elasticity has not been improved, and the feel is relatively rough.
3. Core-covered silk: It has high transparency and excellent elasticity. It completely overcomes the defects of nylon silk and crystal silk. Generally, the tightness is the top grade, and the looseness is relatively poor.
4. Velvet: Compared with cored silk, velvet has slightly less transparency, but its elasticity is much higher. Not only does it feel better, it also increases warmth.
#??#
5. Ultra-thin velvet: Weaving with high-tech ultra-fine fiber full-elastic yarn that is softer than hair, with dense and delicate texture, smooth and silky touch, crystal transparency, and good breath ability.
6. Lycra: A new type of fiber introduced by DuPont of the United States. This fiber can be stretched very easily, but it can be closely attached to the surface of the human body after recovery. The binding force on the human body is small. It's comfortable and fits well on the body. Lycra-containing stockings have better performance in elasticity and resilience, chroma and breath ability.
7. TEDA: High-tech polyester fiber developed by DuPont. It is soft to the touch, breathable and comfortable to wear. The fabric made by TEDA is fine, breathable, soft, comfortable and wrinkle-resistant, and the fabric shines , Clothing as new.
How to clean and maintain stockings
Clean
1. Wash with warm water in a neutral detergent. Do not wring. Use a dry towel to absorb excess water. When washing the stockings, use mild soapy water to soak the stockings for a while. Use mild neutral soap or shampoo to pat gently with warm water (not more than 30 degrees), and absorb excess water with a towel when drying. , The sun is the most jealous, as long as it is directly exposed to the sun, its fiber elasticity fatigue is greatly reduced, and then dry the socks with clothespins, do not dry on a smooth drying rack, easy to hook.
#??#
2. Dry naturally in a cool place.
3. Do not use in the sun or iron.
4. If washing with a washing machine, please put stockings in the washing net before throwing them into the washing machine.
maintenance
New stockings should be soaked in water and placed in the freezer of a refrigerator. After the stockings are frozen, take them out and let them melt and dry naturally so that they are not easily damaged when worn. After freezing the fibers in stockings, the strength of the fibers will increase. Therefore, frozen stockings are less likely to be threaded than ordinary stockings. Similarly, soaking nylon socks in vinegar water has a similar effect. These are all ways to reduce the activity of the molecule. However, the elasticity of the corresponding stockings decreases.
When the socks are threaded, apply a little glue or nail polish to the broken silk ends, and then gently scrape them with your hands. The broken silk ends will stick firmly and will not fall off. Larger, you can take a piece of old stockings of the same color with strong glue, then stick it to the hole, and it will be repaired when it is dry, but be sure to cover the stockings on a smooth cylinder and flatten it. Otherwise it will not be worn if it sticks together.
Stockings are not resistant to high temperatures. It is best to replace the stockings you wear when you work at the kitchen to prevent high-temperature objects such as stoves and ovens from deforming and contracting the stockings, which affects wearing. Stockings are not easy to be gnawed by insects, no insect repellent, sanitary balls, etc. are needed for storage, and they can be stored after washing and drying.

Wool is a natural fiber with excellent wearability. It is the most widely used animal hair fiber in textile products. However, due to the lack of understanding of wool fibers and some characteristics of wool itself, if wool is not properly protected, it can easily cause shrinkage, which not only affects aesthetics, but also is not comfortable to wear. So what to do if the sweater has shrunk? How to wash Cardigans? Let ’s take a look at the Cardigan Show.
Cardigans originally refer to knitted sweaters made of wool, which is also the meaning agreed by ordinary people. In fact, "cardigans" have become synonymous with a category of products, which are used to refer to "knitted sweaters" or "Wool knitwear." Wool knitwear refers to fabrics mainly woven from yarns made from animal hair fibers such as wool, cashmere, rabbit hair, etc., such as rabbit sweaters, snow blue sweaters, sheepskin sweaters, acrylic shirts, etc. are all "cardigan" big families.
The cardigan has the characteristics of good elasticity, bright color, strong extensibility, good breath ability, and comfortable and convenient wearing. Its winter products are light in weight and good in heat retention; the summer products are soft in texture, and the hole effect will produce a good ventilation and ventilation effect, which is cool and comfortable to wear; spring and autumn products can be designed to suit different regions and different consumers according to different requirements Products that meet the needs of all kinds of people.
What to do if cardigan has shrunk?
1. Steam ironing: shrink the sweater fibers with a steam iron, then use both hands to stretch the fibers while hot. You can pad it with white cloth, spray with water, iron some at medium temperature, and the water temperature is preferably around 35 degrees.
2. Cardboard: Use cardboard to cut into the size and shape of the original sweater. The cutout is best polished with sandpaper to avoid hooking the sweater. Put the sweater on the cardboard, fix it with several clothespins at the bottom of the sweater, and then use an electric iron to repeatedly steam iron all parts of the sweater, and then remove it after it has completely cooled.
3. Send to the dry cleaners: Just take the clothes to the dry cleaners, dry clean first, then find a special shelf of the same model as the clothes, hang the sweater, and after the high temperature steam treatment, the clothes can be restored to their original appearance. same.
Cardigan care:
1. Save carefully
Emptying the clothes pockets can cause the clothes to bulge or sag.
Hanging the clothes Hang the wool clothes in a cool, airy place with a suitable hanger, and hang them for a while to remove the wrinkles. Choose a style that supports the shoulder pads and skirt waist of the coat to avoid wrinkling.
2. Prevention of folds
Wrinkles in pure wool can disappear for a period of time or overnight in a wet bathroom.
3.Stain and odor treatment
Rinse the small stain with cold water, and then dry it with a clean cloth, but do not use paper towels; remove the odor from the clothes. Place the clothes on the bed for about an hour, and remove the odor from the clothes such as cigarettes.
4. Let the wool breathe
Allow the wool to breathe for 24 hours before the next wear, and try to avoid wearing the same clothing for two consecutive days. This gives the wool fiber sufficient time to restore its natural elasticity.
5.Storage
If you want to store wool fabrics for a long time, you must wash and dry them. Any wool fabric can be folded and stored, placed on cedar or camphor pills, or hung in a clothes bag. Do not clutter your clothes in tight spaces.
6. Anti-cricket
The moth-proofing of moths is also important. The commonly used method is fumigation, which uses the volatiles of fumigants to kill tapeworms. It needs to be carried out in a sealed container. It is mainly used camphor, naphthalene, p-dichlorobenzene and so on. This method is generally used when keeping woolen sweaters in the home to prevent insects.
7. Renovation
The woolen sweater is shortened and hardened. You can wrap it with a clean white cloth and roll it in a steamer for ten minutes. After taking it out, shake it a little harder, loosen the fibers, and then carefully pull it to its original shape and size. Lay flat on a thin plate or sieve back, dry in a ventilated place and dry in the shade. After drying, it will return to its original shape. Wool or woolen fabrics will gradually lose their original luster when washed more times. If rinsed with water several times, add a few drops of vinegar to the water to continue bleaching to neutralize the acid and alkali, and the woolen and woolen fabrics will recover. The original gloss. Special care for light wool fabrics. Light fabrics such as cool wool, although easy to wrinkle, can be ironed with a damp cloth or a steam iron.
