Abstract

Comfort characteristics of microporous plain-woven fabrics, containing cotton staple fiber twistless and Tencel staple fiber twistless yarn in weft, have been reported in the present paper. The twistless yarn was produced without twist by means of plying with water soluble monofilament PVA filament in the opposite direction. This process was done by TFO (Two for one twister) machine. In all these fabrics the same warp yarn, i.e. a single ring spun 100% cotton yarn was used. The microporous structure of the yarn is created by dissolving the PVA fibers using hot washing of the fabrics. All sample types of twistless yarns and reference yarns are made with a variation in fiber material and fabric picks/cm.The structure of fibrous assemblies in weft has great impact on the comfort related properties, like fabric air permeability, thermal conductivity and also tensile strength and tear resistance. Results indicated that the wickability, and air permeability of the woven fabrics constructed from twistless weft yarn were improved due to the bulkiness of the fabric after dissolving PVA.
