What do you mean by napping textiles?

Question 1: How to distinguish between sanding and napping? Polishing, also called sanding. The process of grinding a short and dense layer of fluff on the fabric surface with a sanding roller (or belt) is called sanding, also called sanding. Warp and weft can produce fluff at the same time, and the fluff is short and dense. Suede is smooth and full, soft to the touch, full of velvet feeling, soft luster and endless light feeling. General sanding is to improve the style and feel of fabric, make it more plump and supple, and make it more comfortable to wear. There are many kinds of sanding, such as ordinary sanding and water milling. Shearing is a watering process for both worsted and woolen fabrics. The purpose is to make worsted fabrics smooth, clear in structure and enhance their luster. Make the suede of wool fabric feel smooth and soft. Brushing: The fabric needs to be brushed before and after shearing. Brush before cutting, the purpose is to remove impurities and loose fibers on the surface of the fabric, so that the fiber tip is upright and easy to cut; After shearing, use bristles to remove chopped fibers and fluff balls, comb the fluff and improve the appearance of the fabric. Sanding refers to rubbing the cloth surface with leather roller or metal roller; Different fabrics with different sand skins can achieve the desired sanding effect. The general principle is to use high-count sand skin for high-count yarn and low-count sand skin for low-count yarn. Sand grinding rollers can be used for forward and reverse rotation, and an odd number of sand grinding rollers are usually used. The factors affecting the sanding effect of sand skin are: sanding roller speed, vehicle speed, cloth moisture content, covering angle, tension and so on. Grabbing is to insert a steel wire bending needle with a certain angle into the yarn and hook off the fiber to form hairiness; It means the same as taking a nap, but it is different; Different fabrics use different steel needles, which are divided into round heads and pointed heads. Generally speaking, cotton uses a pointed head and wool uses a round head. The influencing factors are: vehicle speed, card clothing roller speed, number of card clothing rollers, moisture content, tension, card clothing density, bending angle of steel needle, yarn twist, auxiliaries used in pretreatment, etc. Bristles are swept on the cloth surface by a bristle roller like a brush; Different fabrics and treatments use different bristle rollers, including bristle brushes, wire brushes, carbon wire brushes and ceramic fiber brushes. Bristle brush for simple treatment, such as brushing cloth before singeing; Wire brushes are generally fabrics that need to be lifted, such as knitted flannel; Carbon brush is used in high-grade cotton fabric, and the surface treatment requires fine; This treatment requires the use of finer ceramic fibers. Influencing factors: number of brush rollers, rotating speed, brush line stiffness, brush line fineness, brush line density, etc. The equipment used in the sanding process is a sanding machine, which uses rollers such as sand skin, carbon and ceramics to grind microfibers in fabric yarns to form a surface fluff effect. Compared with the sanded products, the fluff is short and dense, and the wool feeling is very delicate. Specific products include sanded yarn card, sanded poplin, peach skin velvet, etc. Some sanded products are not obvious in appearance, but their hand feel is greatly improved.

Question 2: which is better, sanding or napping, refers to the strip or flower-shaped concave-convex pattern woven on the cloth. It can be divided into big jacquard and small jacquard. Jacquard is a flower pattern, and small jacquard is a simple geometric pattern such as strip or lattice. The cost of jacquard should be higher than that of small jacquard. Jacquard gives people a more gorgeous feeling and a higher price.

■ Grey cloth

Also known as white blank, the unbleached, dyed and printed cloth woven from primary color cotton yarn is collectively referred to as primary color cloth. Generally called grey cloth.

■ Washed cloth

It is a special dyeing and finishing process, which gives the fabric a slightly wrinkled washing style. The raw materials of washed cloth are pure cotton, polyester cotton and polyester filament. The washed fabric is soft to the touch, stable in size, comfortable to wear and slightly wrinkled in appearance. Mainly used as coats, suits, shirts, pants, pajamas, etc.

■ Poplin

It is a plain cloth, and it is also woven with plain weave. Warp and weft are both fine yarns, which belong to fine and extra-high warp density fabrics. They are crisp and smooth, and can be used to make shirts.

Compared with plain cloth, the warp-weft density ratio is generally 1.8 ~ 2.2: 1. Because the density of warp yarn is obviously higher than that of weft yarn, diamond-shaped grains composed of raised parts of warp yarn are formed on the surface of fabric. Poplin fabrics are usually made of pure cotton or polyester-cotton fine yarns. According to the different yarns used, it can be divided into yarn poplin, half-thread poplin (yarn in warp direction) and thread poplin (yarn in warp and weft direction). According to different spinning projects, it can be divided into carded poplin and combed poplin. According to the weaving color, there are hidden poplin, satin poplin, jacquard poplin, colored poplin and flash poplin. According to the printing and dyeing process of natural poplin grey cloth, there are bleached poplin, variegated poplin and printed poplin. All kinds of poplin fabrics have the characteristics of smooth cloth surface, fine texture, full grain surface, bright and soft luster, soft and smooth feel and so on. Poplin is the main variety of cotton cloth. Mainly used as shirts, summer clothes and daily clothes.

■ Bali yarn/glass yarn

Also known as Bali yarn/Bali yarn, a thin and transparent plain fabric. The characteristics of glass yarn are: fine combed strong twist yarn is used in warp and weft, and the density of warp and weft in fabric is relatively small. Due to "thin" and "thin" and strong twisting, the fabric is thin and transparent, with clear holes, light and thin texture, transparent and breathable, and smooth to the touch, and can be used for curtains or summer clothes.

■ Cotton card

Shaka is a kind of khaki, which is a twill fabric. The varieties are divided into line cards (the warp and weft are evenly twisted), half-line cards (the warp and weft are single yarns) and yarn cards (the warp and weft are single yarns) according to the used warp and weft.

The line card adopts 2/2 right twill weave, and the diagonal lines on both sides are obvious, which is also called double-sided card;

Half thread card adopts 3/ 1 right diagonal weave, and yarn card adopts 3/ 1 left diagonal weave.

Half-line cards and yarn cards are both single-sided cards. The raw materials used in khaki are mainly pure cotton, polyester cotton and so on. This kind of fabric is dense and thick, with obvious lines and durability.

■ Yarn-dyed fabric

Refers to the cloth woven from dyed yarns. Usually the colors of warp and weft are different. For example, the warp is red and the weft is white, which makes it a lighter pink.

The advantage of yarn-dyed fabric is that the yarn is dyed first and then woven into fabric. The color fastness is better than that of ordinary printed and dyed fabric, and it is more difficult to fade when washing.

■ Youth cloth

Pure cotton fabric woven with plain weave. Youth cloth is also yarn-dyed, which is different from ordinary (bleached) cloth, with strong three-dimensional effect (partial particle effect) and good dyeing fastness.

Warp and weft have different colors, one is dyed yarn and the other is bleached yarn. Usually, warp and weft have the same density and are close together. The cloth cover of youth cloth is a two-color effect, with harmonious and elegant colors, special style and light and soft texture. Mainly used as shirts, windbreakers, children's clothing fabrics and quilt covers.

■ Denim: The warp dyed with pure cotton indigo and natural weft are interwoven into a three-layer twill weave, which can be generally divided into three categories: light, medium and heavy. The width of cloth is mostly between 1 14- 152 cm.

Fabric weight (g/m2) Yarn count thickness (inch count)

Light weight 200-340g/m2 (6- 10 ounce/square yard) 12x 12 or more.

Medium 340-450g/m2 (10-13oz/m2)10x10.

Heavy-duty 7×6 denim over 450g.

Features: 1, pure cotton coarse twill, moisture permeable, breathable and comfortable to wear; 2, the texture is heavy and the lines are clear. After proper treatment, wrinkles, shrinkage and deformation can be prevented; 3. Indigo is a harmonious color, which can be matched with coats of various colors and is suitable for all seasons; 4. indigo is >>

Question 3: How much is a wool puller in a textile factory per month? Depending on which city, third-and fourth-tier cities, the salary is determined according to the basic salary and workload, which is about 3,000-4,000.

Question 4: How to adjust the parameters of textile napping machine? How to tune the tails? How to adjust the front? I thought there was a plucking master,

Question 5: What is the silk napped scarf made of? Very very comfortable.

When you meet a good one, you must buy it. I liked it when I bought it, hehe

Question 6: What do you mean by adding velvet? That is to say, some fabrics in the lining are velvet like the lining in the sweater, which feels a bit like a thin blanket, very soft and comfortable! That's about it!

Question 7: Hello, what does TOP in textile industry mean? And what post-treatment does polar fleece usually have? What is the post-treatment of double-sided cloth? According to the specific situation,

Top dyeing generally refers to hemp grey yarn, which doesn't look like it here.

Look at your story. It's a filament.

50D T + 20D OP，

50D polyester filament +20D spandex

OP stands for spandex T is polyester.

General polar fleece is like this. Towel cloth-dyeing-shaving-napping-shearing-shaking-setting.

Ordinary double-sided fabrics are generally dyed and shaped, and there are too many kinds of double-sided fabrics.

Question 8: How much is the fabric napped? How much is one meter? Does the wool content of 50 meters lose time? A few hundred meters is just a nap. It depends on the texture of your fabric and the number of yarns. The yarn has high twist, fine yarn, slow napping and more napping times. The price of each pile is 0.05-0. 10 yuan/meter. Plus the cost of finishing, it's about 0.5-0.8 yuan. If it is raised eight times normally, the price will be between 0.9- 1.6 yuan. Of course, prices will vary from place to place.
