A method for preparing a knitted felt fabric by using water-soluble filaments to spun low-twist wool yarn and the knitted felt fabric itself.

This invention belongs to the field of textile materials technology, and provides a method for preparing low-twist wool yarn spun with water-soluble filaments for knitted felt fabric, as well as the knitted felt fabric itself. This invention utilizes the reinforcing effect of water-soluble filaments during spinning to significantly reduce yarn twist while maintaining high strength. By reducing the twist of the fine yarn, a loosely structured wool yarn can be obtained, improving the effect and quality of felting. Combined with the reinforcing effect of water-soluble filaments, this invention resolves the contradiction between the textile processing strength requirements and the loose structure needed for felting in knitted felt fabric yarn. By controlling the spacing between the water-soluble filaments and the wool roving, as well as the type of the twist triangle, the water-soluble filaments and wool roving can form intertwine without covering, thus ensuring yarn strength while achieving successful dissolution of the water-soluble filaments. The results of the embodiments show that the breaking strength of the low-twist wool yarn spun with water-soluble filaments provided by this invention is 397.60 cN.
