Xiaobian: I Learned Knowledge Of Clothes And Fabrics Five

Generally speaking, the polyester staple fibers in the market are divided into 3 categories.

large chemical fiber :

Short fibers made from PET chips or direct melt spinning.

Its characteristics are good color, large batch number, strong stability, few defects and good spinnability.

China chemical fiber:

The price quality is between large and small size by using equal PET slices or PET back spun.

Small chemical fiber: with PET feed, the price and quality are uneven. It is suitable for the national conditions and exported to some markets and fields where quality requirements are not too high (such as filling materials, etc.).

Generally speaking, there are basically no defects in the short fibers made of sliced yarn. The fibers are uniform and smooth, and the handle is smoother. However, where the short fibers are used, there is a difference between adding silicon and not adding silicon to coarse ones. With hand pull, the general strength of sliced spinning is better, the batch number is large, there is no color difference, and the physical index is even.

Generally speaking, the production of small chemical fiber, or short fiber produced by recycled raw materials, is small, and the same algebraic feel is not as good as large chemical fiber (except processed). There are many defects, occasionally uneven in thickness and large in length. Generally, the physical index of conventional recycled materials is slightly worse.

GAUGE machine: the number of needles with 1 inches on the needle in the circular knitting machine.

soybean protein fibre

The properties of the fiber are superior, with many advantages of natural fiber and chemistry. It has not only the characteristics of single filament, fineness, light weight, high strength and elongation, good acid and alkali resistance, good gloss, good hygroscopicity, but also has a soft handle of cashmere and a soft luster of silk. Cotton fiber The moisture absorption and moisture conductivity of the wool, the warmth retention property of wool and other excellent wearability.

Because of its excellent properties, the fiber can be widely used in the field of clothing. The pure spinning of soybean protein fiber is interwoven with wool, silk, cotton and so on.

The new clothing material is a high-end fabric that can satisfy the comfort of consumers and meet the aesthetic characteristics. It can produce high-grade underwear, cashmere sweater, body clothing and high-end casual wear, Western-style clothes, sportswear and so on. It has unique styles of different general products.

The high energy technology is used to separate the globulin from soybean meal and purify it. Through the grafting, copolymerization and blending of the auxiliary with nitrile group and hydroxyl polymer, a certain concentration of protein spinning solution is prepared.

Tencel: cellulose fiber is a kind of cellulose fiber. It adopts solvent spinning technology. Its strength is slightly lower than that of polyester fiber, but it is obviously higher than that of viscose fiber. Its moisture strength is obviously improved than that of viscose. It has very high rigidity, good washing size stability (shrinkage rate is only 2%), and has high hygroscopicity. The fiber cross section is round or oval, with beautiful luster, soft handle, good drape and good flowing quality. In general, Tencel has 1 of cotton softness, 2 of polyester's high strength and 3 of hair's warmth, but it is easy to harden in damp and hot conditions, and it is not good in cold water.

Processing silk is changed silk, raw silk is called the original bar, not used, relatively pure new, regenerated silk is low grade, used inferior goods.

General FOB calculation of after tax prices:

Factory price / (1+ rebate rate) * (1+ company cost rate) / expected exchange cost =FOB US dollar price

Letter of credit (L/C) is a certificate that a bank should pay to the exporter under certain conditions to guarantee payment under the condition that the bank requests the importer.

Bill of lading (B/L) is a certificate issued by a shipping company or its agent, which proves that a specific cargo has been received, allowing the goods to be delivered to a specific destination and delivered to the consignee.

The seller receives the foreign exchange by L/C, and the buyer takes the goods by B/L.
