180gsm tr fabric principle

The 180gsm tr fabric is a new spinning technology for spinning on a new and improved ring spinning frame. The spinning mechanism is as follows: a fiber condensation zone is added in front of the traction device of the ring spinning frame, and the spinning twist triangle zone between the front roller and the twist point is basically eliminated. After the fiber strip is output from the front of the roller, it first passes through the mesh eyelid of the shaped air suction tube. The strip moves on the mesh eyelid. Due to the contraction and aggregation of the air flow, the strip gathers and rotates through the air suction groove of the shaped tube, and gradually turns from a flat ribbon to a cylinder. 180gsm tr fabric yarns are stronger and less feathery. In the process of weaving is least likely to produce abrasion phenomenon.

The purpose of the 180gsm tr fabric is to make the fibers as parallel and close to each other as possible before twisting, which is an important criterion for high quality 180gsm tr fabric yarns. Making the fibers as parallel and consistent as possible before twisting is the premise of its advantage.

Advantages and disadvantages of 180gsm tr fabric

(1) Advantages:

1. Because before twisting, the single fiber in the yarn strip is fully extended, parallel to each other, and closely arranged, so at the twisting roller clamp (also known as the twisting roller, because it has the effect of preventing twist transfer), the diameter of the yarn strip becomes small, so the "twisting triangle area" is basically eliminated, because the single fiber is fully extended and parallel before twisting, there is no hair stretching out the main body of the yarn strip. Therefore, there is very little hair into yarn, especially if it is more than 3 mm.

2. In fine yarn, because each single fiber is twisted in a straight and parallel state, when the single yarn is subjected to tension, the force of each single fiber is basically the same, so the strength of 180gsm tr fabric is higher than that of traditional single yarn. And because the single fibers in the tight yarn are closely arranged, the adhesion between each other is large, which also helps to improve the strength of the yarn.

3. In the 180gsm tr fabric process, the yarn is gathered after the completion of the draft specified by the process, so the index of uneven yarn is not greatly improved, but the effect of finishing yarn in the gathering area, and the inner and outer layer transfer of fiber during twisting at the mouth of the twisting roller is not as strong as that of the traditional process, so the yarn is uneven. Coarse and detailed indicators are better than traditional yarn.

4. Because of the above characteristics of tight yarn, it provides very good conditions for the next process, and the tight yarn has less hair, so the pressure of sizing, singeing and other processes is reduced, and the resistance of filling insertion is greatly reduced when the weft yarn is used in the shuttleless loom, and the loom efficiency is improved.

5. Because the compact yarn fibers are arranged closely and the diameter is small compared with the traditional yarn of the same number, the cloth woven with the same warp and weft is good in air permeability, and the cloth surface is flat and smooth, which is the ideal yarn for high-grade textiles.

(2) Disadvantages:

The high cost of 1.180 gsm tr fabric equipment increases the equipment investment of the spinning mill.

2. In addition to the wool index has a great improvement, other indicators such as yarn dry, thick, detail and so on, the improvement is not large.
