Each of the hanks is yards long, so the total length of the yarn is 8, yards. So, if its a coarser yarn it will take fewer hanks, and less length to make up a pound. On the other hand, the higher the number, the finer the yarn. Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family fiber is almost pure natural conditions, the cotton bolls will increase the dispersal of the seeds.

The plant is a shrub native to tropical and subtropical regions around the world, including the Americas. Textile fibers can also be classified in the following ways: Classification of textile fibers based on sources ; Classification of textile fibres based on polymer ; Classification of Textile Fibers Based on Sources: With this concept, the classification of fiber was established as per its source and it is mentioned in Fig The Cotton Program, within the U.S.

Department of Agriculture (USDA), has consistently strived to improve its cotton clas-sification system. One endeavor that has taken over 30 years to implement is the transfer of the manual cotton classification program to an instrument-based system.

Universal HVI Calibration Cotton Standards are samples from bales of ginned cotton lint with established standard values for length, length uniformity index and strength. These standards are used for calibration of instruments testing Upland cotton varieties. Approximate Net Weight: 5 pounds each.

Scope. This practice provides two options for the qualification of cotton classification instruments: option 1, newly installed cotton classification instrumentation, or option 2, annual verification of cotton classification instrumentation using evaluation cottons, trash evaluation images, and color evaluation fiber samples for the fiber measurements of micronaire reading, upper half.

In addition to bale uniformity requirements, each bale must meet the length and strength criteria for its intended use. For example, an Upland long/strong calibration cotton bale must have approximate length and strength values of to inches and 32 to 36 grams per tex, while an Upland short/weak calibration cotton bale must have length and strength values below inches and 23 to.
