Description

Small quantitative cotton fiber folding sample preparation device

technical field

The invention belongs to the technical field of textile testing equipment, and more particularly relates to a small quantitative cotton fiber folding sample preparation device.

Background technique

At present, in the textile field, yarn quality is an important indicator to determine the quality of textiles, and an important quality indicator in spinning production is the short-staple ratio, which refers to the weight of short-staple fibers in cotton fibers with a length shorter than a certain limit ( or the number of roots) as a percentage of the total fiber weight (or the total number of roots), the cotton fiber lint rate is an important technical indicator for evaluating the quality of raw cotton, and the cotton fiber lint rate has a very important impact on the quality of textiles and production processes. Generally, short fibers with a length of less than 16 mm are called cotton linters. The less cotton linters in the raw cotton, the higher the utilization rate; the high lint rate will damage the use value of cotton and increase the textile process. The cost of cotton consumption will be reduced, the production efficiency will be reduced, the uniformity of cotton yarn will be destroyed, and the yarn strength will be reduced, which will eventually lead to the increase of end breaks and yarn defects in the manufacturing process, reduce the textile production rate, and affect the quality and appearance of textiles.
