How to calculate the difference of knitted fabrics and how to calculate the difference of fabrics

The difference and paper tube are only for the fabric you buy by the pound, and they are the kind that are rolled. As the name suggests, the paper tube is a roll of fabric with a paper tube in the center, and the air difference is that there is no paper tube in the center. The fabric with a paper tube is basically deweighted when weighing, but it has no effect on the number of meters.

Knitted fabrics are sold by the kilogram, and there are three ways to sell fabrics: net cloth, full scale, and empty difference. A piece of cloth needs to be rolled into a paper tube, and the natural paper tube is a kilogram weight.

The significance of the paper tube lies in the first, rolled into a piece of cloth, and second, the paper tube is also a necessary factor to participate in the pricing method, and the weight of the paper tube is related to the number of kilograms of a cloth.

Buy woven fabric and he will give you short size, buy knitted fabric and he will give you empty numbers and paper tubes, this is the rule of the university.

Because the ** of the veil on the market fluctuates every day, and your medium and large finished yarn-dyed fabric cannot have a price a day, so customers can't accept it (so they will ask you if you ask ** with empty numbers and paper tubes, or ** without it**). Therefore, our "great" merchants, with their "excellent" wisdom, pioneered "98" and "empty numbers" and "paper tubes". Knitted fabric term (malleable), because there is no guarantee that the upward tensile force is not received at all when measuring, so it is calculated by weight.

The empty number is the same as the short code of the weaving, that is, the actual weight of a roll of cloth is 20kg, and he charges you 24kg of money, paper tube: I won't say it, genius idea.

In short, Zhongda is always in line with the price increase in the domestic market, but the price reduction is always half a beat. When you ask ** in the future, remember to ask these nouns clearly.

Is it enough to remove the empty difference?

1. In terms of raw materials, there are natural fibers (cotton, wool, silk and linen), regenerated fibers (viscose, cupra, acetate, modal......Synthetic fibers (polyester, nylon, spandex, acrylic, ......）

2. From the weaving method: knitting, weaving.

3. From the fabric structure: plain weave, twill, satin, skein, linen yarn, jacquard 4, from the processing technology: twisted crepe, no twisted plain.

Combine the various categories mentioned above, and you'll get thousands of different fabrics.

Clothing fabrics are the materials used to make clothing. As one of the three elements of clothing, fabric can not only be interpreted. To make clothing worn in formal social occasions, it is advisable to choose pure cotton, pure wool, pure silk, and pure linen products.

Most of the clothes made of these four pure natural textures are of higher grade. Sometimes, it is also permissible to wear clothing made of pure leather. .

According to the regulations, the Ministry of Foreign Trade and Economic Cooperation of the People's Republic of China shall, at the beginning of each year, directly allocate the quotas to foreign trade enterprises and provinces that undertake textile export plans and have actual export performance and have the right to operate textile exports.

Warp dosage per meter: 133 63 (5315 40) 9000 weaving) = 136 grams, of which the weaving shrinkage varies according to the thickness and density of the weft, the thicker and denser the weft, the higher the weaving shrinkage.

Weft yarn per meter: 72 63 (5315 40) 9000 = 70 grams and then multiply the yarn price by the yarn price per meter, for example, 40s combed yarn is 25 yuan kg, then the cost of the fabric yarn is (136 + 70) 1000 25 = yuan.

Coupled with the weaving cost, the general arrow shaft machine is 3 minutes and one weft, that is: 72 * yuanExtended MaterialsKnitted fabric washing:

1. Various detergents can be used, which can be washed by hand and machine, but should not be chlorine bleached.

2. White clothes can be washed at high temperature with alkaline detergent to play a bleaching role.

3. The fabric should not be soaked for too long to avoid the fabric fading.

4. It should be dried in the shade, avoid exposure to the sun, so as not to fade the dark clothes, and when drying in the sun, the inside should be facing outward.

5. Be sure to wash separately from other clothes, not together.

6. Do not wring it out to avoid wrinkling.

Conversion in knitted fabrics: length x width = area, area x gram weight g m2 = weight formula 1:

Yardage = meters.

Cloth seal (inches) x = meters.

1000 = Convert grams in gram weight to kilograms.

The essence of Equation 1 is that total length x width x gram weight = kilograms I think is correct.

Equation 2: ?

Formula 3: Completely wrong, find the length, should: total weight gram weight = area, area width = length, and then convert into yards. Note, but only in units.

Note: grams square meters, ounces square yards, 1 gram = ounces, 1 gram square meters = ounces square yards, 1 ounce square yards = grams square meters.

In this kind of conversion of the metric system, it is indeed easy to make mistakes, and it is recommended that the units are now unified, and they are all converted to the metric system first, and then calculated. It is easy to make mistakes in the calculation while converting.

Good luck!

Yard length = kg * 1000 yard weight. Kilograms = yard weight * yard length 1000Yard weight = edge-to-edge width (inches) * gram weight (gram weight per square meter) * coefficient, some say and.

1. All fabrics will have flaws, not only short sizes, but also color differences, weft obliques, cloth edges, wavy color differences, and so on.

2. Wear and tear is the loss that must be added when making clothes, depending on the type of fabric, the form of clothes, typesetting and so on.

3. The shrinkage rate is 3-4%, that is, the shrinkage rate of the fabric refers to the percentage of fabric shrinkage after washing or soaking in water.

4. Human cotton is only a material, and all kinds of materials can be knitted or condensed.

5. Questions to ask when buying fabrics:

1) First of all, we should ask about the material and amplitude, as well as the level of the goods;

2) When receiving the goods, each cloth should be opened to take a look;

3) When inspecting the fabric, the luster and shade, dyeing, surface thickness and structure, texture and appearance characteristics of the fiber, the softness and hardness of the fabric and the fiber, smoothness, thickness, elasticity, cold and warm, etc., can also measure the strength and elongation of the yarn in the fiber by hand.
