The Gap Between Cotton Quality And World Cotton Quality In China

< p > > a href= "http://fz.sjfzxm.com/" > < < /a > > reports show that in order to find out the difference between the quality of China's cotton and the quality of the world's cotton, we conducted tracking tests on the quality of cotton in main importing countries (USA, Brazil and Australia) in 2012 and 2013 in Qingdao, Shanghai and Guangzhou respectively, and compared the quality of cotton made in China with those made in China.

It is found that the main disparity of cotton in China lies in the following seven aspects: < /p >

< p > 1. domestic cotton "three silk" phenomenon is more common.

Because most of China's cotton is picked artificially, the cotton farmers' poor sense of "three silk" leads to different levels of "three silk" in cotton.

Even though there are very few parts of Xinjiang's machine picked cotton, many years of continuous use of plastic film for planting cotton, the old plastic film is blown to the top of the cotton plant, so that the processed lint contains small waste plastic film.

Cotton mills must receive orders that require strict coloring. Only cotton, cotton and Brazil cotton are selected.

"Three silk" has become the biggest quality problem of cotton in China.

< /p >

< p > 2. Chinese cotton varieties are single and can not meet the needs of various textile varieties in cotton mills.

At present, China is mainly planting fine staple cotton, and Xinjiang has a small amount of long staple cotton.

The length of fine staple cotton grown in China is mostly 28mm.

Imported cotton varieties cover coarse staple cotton, fine cotton and long staple cotton. The fiber length is 23mm to 38mm, and the micron value is up to 7, and the selectivity is strong.

< /p >

< p > 3. the strength of cotton fiber in the main cotton producing area of China is very low.

It can not meet the needs of Chinese textile enterprises to produce high-grade textiles.

In 2014, cotton production in Northwest China's inland cotton area will account for more than 70% of the total cotton output in the whole country. However, the breaking strength of most cotton is below 28cN/tex, and some even 24cN/tex, which seriously restricts the spinnability of Chinese cotton.

The breaking strength of Australian cotton, India cotton and some American cotton is over 31cN/tex, and the breaking strength of West African cotton is more than 28cN/tex.

< /p >

< p > 4.. The length of Chinese cotton can not meet the needs of spinning high count cotton yarn.

With the improvement of people's living standard, high density and high count textiles are popular with consumers for their comfort and comfort. However, the production of more than 60 cotton yarn needs more than 31mm cotton length. If the long staple cotton is used, the cost will be greatly increased. Therefore, only 1-7/32 cotton or MCU5 India cotton should be selected in the textile industry. In order to reduce the cost, the production of high-grade airstream spinning cotton yarn will have to use imported cotton with length 23mm to 26mm, such as V797 in the India.

< /p >

< p > 5. the adulteration of Chinese lint often occurs.

Driven by interests, some illegal enterprises incorporate combed noil and cotton washing in cotton processing, and develop from the 200 type cotton processing plant to the 400 type cotton processing plant.

2012, 2013, during the annual storage and storage of cotton, the import of combed noil in China's main ports is still more than 1000 yuan / ton, and the supply price is still in short supply.

I saw in a repository of cotton, short fiber rate is high, unprecedented.

China's cotton standard has no limitation on the index of short fiber rate, and it provides an opportunity for lawless elements.

In addition to the occasional cotton lint found in India cotton, the imported cotton rarely found such phenomena in other countries.

< /p >

< p > 6. the problem of mixed grade processing is outstanding.

Mainly in the 3 years of storage, some cotton processing plants in order to make the late cotton value of the low horse clone value of the late cotton and storage, the later yellow cotton and pullout cotton peeling cotton and the prophase high horse clone value cotton mixed grade processing, seriously affecting the cotton dyeability and strength.

< /p >

< p > 7.. The integrity of individual cotton processing enterprises is poor. In the process of processing cotton, counterfeit producing areas are even repackaged with high sugar Sultan cotton and Mexico cotton. After that, China's origin logo is painted, causing serious quality problems.

For example, a cotton processing enterprise returned to the sold cotton reserve because of the discovery of the cotton quilt. The company publicly stated that the cotton that had been withdrawn from storage was processed by AAO cotton. Due to honesty, though the cotton was indeed close to the quality index of the cotton, no cotton mill was willing to purchase and use the plant's cotton according to the price of Australia cotton.

This is the price of honesty.

< /p >

< p > aiming at the existing gap, how to reduce and eliminate gradually, the author thinks, first, we must strengthen the market allocation of cotton resources and achieve the survival of the fittest; two, we should strengthen supervision, let the bad faith and the illegal operation pay the price or go out; three, strengthen the scientific research of cotton, and find out the reasons for the low strength of the northwest inland cotton and solve them in a targeted way.
