The Mechanical Properties of New Worsted Wool-like Fabrics Using Latent Yarns

A fineness range of 150 Nm-170 Nm has recently been applied to produce much finer wool products, so that processing techniques for the wool fabrics have been developed very rapidly. However, the worsted wool-like technique using polyester fiber has not been still implemented in general processing technique. Therefore, this research is to develop materials of side-by-side type with high finess, high shrinkage and stretchability. The mechanical properties of the produced fabrics were analyzed and the fundamental information were obtained for the new worsted wool-like products. The physical properties of a latent crimped yarns of side-by-side type with stretch function are analyzed. Also the mechanical properties of five kinds of fabrics are analyzed, which are produced with non-circular shape(+type) warp yarns of a twist of 1000(T/M) and with two kinds of latent weft yarns of a twist of 1000 T/M and DTY respectively.
