1. The yarn should have a certain strength and extensibility: the strength of the yarn is an important quality indicator of the knitting yarn

2. Yarn should have good softness: the softness of knitting yarn is higher than that of weaving yarn.

3. The yarn should have a certain twist: the twist of the knitting yarn is lower than that of the woven yarn, but the twist of the knitting yarn should not be too low, otherwise it will affect its strength

4. The linear density of the yarn should be uniform and the yarn defects should be less: the uniformity of the linear density of the yarn, that is, the uniformity of the yarn evenness, is an important quality indicator of the knitting yarn.

5. Yarn should have good moisture absorption: the yarn used for knitting production should have a certain degree of moisture absorption.

6. The yarn should have a good smoothness and a small friction coefficient: the knitting yarn should be free of impurities and oil stains as much as possible, and should be very smooth.
