Long-staple cotton
Long-staple cotton has a long growth periodicity and requires a lot of heat. Under the same heat conditions, the growth periodicity of long-staple cotton is 10-15 days longer than that of upland cotton. Long-staple cotton fibers are slender and lustrous with high strength and high quality. It can be spun in high-count yarns. It is an important raw material for spinning high-end and special cotton textiles. It enjoys "the best of cotton" and "cashmere texture, silk luster" and other reputations.
In addition to Xinjiang long-staple cotton in our country, Egyptian long-staple cotton and American Pima cotton are also long-staple cotton species. The output of long-staple cotton is not high. According to a report issued by the International Cotton Advisory Committee (ICAC), the output of long-staple cotton accounts for only 1.5% of the total global cotton production. How precious they are!
Which long-staple cotton is better? Xinjiang long-staple cotton, Egyptian long-staple cotton or American Pima cotton?
Long Staple Classification | Fiber Length(mm) | Short Fiber Index (%) | Micronaire Value | Maturity Rates | Impurity Rates | Moisture Regain | Fiber Uniformity | Fiber Fineness(Mtex) | Cotton Knots |
Xingjiang Cotton | 37.29 | 6.9 | 4.22 | 0.98 | 3.6 | 5.7 | 86.3 | 161 | 101 |
Egyption Cotton | 35.74 | 8.9 | 4.22 | 0.98 | 2.8 | 5.7 | 89.7 | 159 | 127 |
Pima Cotton | 35.89 | 6.5 | 4.22 | 0.98 | 3.1 | 5.7 | 87.1 | 171 | 136 |
The above table lists 9 factors that affect the quality of long-staple cotton. According to this evaluation, Egyptian cotton has the best overall performance, Xinjiang cotton has an advantage in main body fiber length, and Pima cotton has a high reputation, but it is not as high-quality as expected. The superiority of Xinjiang cotton depends on its unique environmental advantages.
