Quality Characteristics And Market Prospect Of Roller Cotton

Quality characteristics of roller cotton

1. compared with sawtooth cotton, the cotton roller cotton has fewer harmful defects, which is shown in no silk and cotton seed knot, and fiber seed chips are less than sawtooth cotton.

Because the principle of the roller roller is mainly the traction of the roller and the blocking of the cotton seed, and the impact of the knife on the cotton seed, so that the fiber and cottonseed can be separated.

The main parts are low in wire speed, and the blow to the fiber is much smaller than that of the sawtooth cotton gin, so there are few harmful defects.

Most of the cotton seeds broken by impact knives were larger seeds and less fiber seed chips.

2. the sawtooth cotton with better fiber length than the same seed cotton.

The high speed drag and friction of the sawtooth cotton gin can cause some long fibers to break, resulting in a decrease in length, especially when the moisture content of the seed cotton is too small.

Reduce length and uniformity.

The roller roller is a low speed traction roller with few fibers.

The length of roller cotton made of the same seed cotton is longer than 0.5mm of sawtooth cotton.

This is the reason why cotton roller must be used for long staple cotton.

3. the evenness of cotton roller and sawtooth cotton has different effects on textile.

The short fiber ratio of leather roller cotton is mainly yellow root, that is, fibers less than 3mm. It is easy to discharge in the carding process, forming chopper cotton or falling down to form noil, while the uniformity of sawtooth cotton is the broken fiber formed by different lengths, which has great influence on textile.

This concept can be clearly seen from the cotton bundles, and feel that the roller cotton is better than the sawtooth cotton.

4. leather roller cotton fiber level is clear, hit lightly, fatigue degree is better than sawtooth cotton.

The degree of entanglement between the fibers is light. The same level of roller cotton and sawtooth cotton can be seen after carding machine combing. After the cotton roller is combed, the fiber level is clear, single fiber is good, the plumpness is good, the mercerizing is good, and the sawtooth cotton is far inferior to the roller cotton.

5. leather roller cotton has yellow root, affects the appearance color, increases the short fiber content, because the roller roller has no impurity device and lint cleaner, so the impurity is bigger, but the impurity area of the roller roller cotton is large, so it is easy to clean up.

Although there is no cotton cleaning machine, the advantage is to reduce the damage to the fiber and avoid the formation of harmful defects.

6. the woven bag foreign fibers in seed cotton are not easy to be broken by low speed rotating rollers in the roller roller, and are easy to pick when used.

Leather roller cotton has unique use value.

Spinning high grade cotton or knitted cotton yarn requires better bar and fewer impurities. Proper proportion of roller cotton can effectively reduce impurity content and increase evenness.

Because the defects in the roller cotton are mainly sterile seeds and broken seeds, which are less harmful. Sterile seeds and broken seeds are easy to be cleaned in carding process.

Unlike fibrous defects such as neps, wires and fiber chips in sawtooth cotton, they are not easy to be cleaned up, so they are called harmful defects in textiles.

Harmful defects not only increase the content of cotton yarn, but also affect the evenness of cotton yarn evenness.

In cotton blending, the quality of cotton yarn is improved by using the complementary characteristics of cotton roller and sawtooth cotton.

The outstanding quality problems of leather roller cotton processing in the mainland are poor or bad cleaning of seed cotton, poor selection of seed cotton and foreign fiber, widespread processing of high moisture seed cotton, so the processed roller cotton has large impurity, big yellow dye, large moisture regain and poor color.

Because of the small moisture content of seed cotton in India's roller roller cotton, the processed roller cotton has little impurity, good color and little yellow dye.

There are also few foreign fibers.

It can be seen that the domestic fine cotton roller cotton can not compete with India roller cotton at all.

It is an important task for us to improve the quality of domestic roller cotton as soon as possible.
