Structure design of unidirectional moisture transfer fabric with high wool content based on multiple differential...

The natural functions of wool fiber, such as natural air permeability, dryness of skin contact, have advantages in the development of sports fabric. So far, the development of unidirectional moisture transfer fabric with high content wool is not yet mature. This paper novelly designed a ply yarn formed by different content of wool and nylon yarn and a double-sided knitted fabric with different wool content in the inner and outer layers based on unidirectional moisture transfer principles. The results showed that the difference in wool content between layers had a significant effect on the cumulative one-way moisture index, while small yarn linear density change had no significant effect on this index, but had a significant effect on the surface diffusion rate. The cumulative one-way moisture conductivity indexes of samples 1/9, 1/8, 1/6, 1/7 and 1/5 were all above 400, with the rating of 5, indicating excellent one-way moisture conductivity, so the one-way moisture conductivity of the fabric with high wool content is realized. The application of this technology will provide better moisture absorption and perspiration performance and wearing comfort for wool sportswear fabrics.
