Polypropylene staple fiber are fibers that are shorter than the length of the main fiber length in cotton fibers. Common polypropylene short fibers comprise a percentage of the total mass of the fiber, called short velvet. There are two main reasons for short fibers:

The first is that the fibers are generated when it is grown, and the raw materials in the time of the cotton, especially shorter length (12 mm or less);

The second is the damage of the fiber during the machining process, and the sequence produced by the combing process is turned off, combats and combed. The length of short fibers: foreign fiber is mainly 10 mm, in addition, the UK and Switzerland are short fibers with average length below the fiber; domestic quality control generally uses the fiber length of 12.7 mm and 16 mm. Two kinds of analysis. Different lengths have different effects in the spinning process, and the short fibers of 4 mm to 5 mm generally lose from the spinning process; the short fibers of 12 mm to 15 mm can only fill the yarn to achieve Full effect, there is no contribution to strong contributions; the fibers of 16 mm to the internal and external features of the yarn produce a positive impact.

Polypropylene staple fiber  are easily formed in a large amount of cotton knot in the opening of cotton and comb, which increases fiber quality, increased cotton and cotton cost; during the process of combing and crude process, short fibers are not easy to control, formation The floating fibers affect the fiber shift; during the twisting process, the short fibers are easily extended out of the surface of the yarn, and form a hair and affect the style.
