A STUDY ON THE COMFORT PROPERTIES OF MULTI LAYER WEFT KNITTED FABRICSK. THANGAMANI AND S. SUNDARESANAbstract Apparel industry has been using stretchable fabrics for years and apparel marketing campaigns have done a good job advertising the temperature control and moisture management factors as benefits to consumers. Most consumers have experienced pleasing benefits when wearing apparels such as stockings, long johns, bras, briefs, gloves, headbands, made from fabrics with a compression factor. In this research work adetailed study on the properties of Polyester and Cotton weft knitted multilayer fabric with various loop lengths has been done. The multi-layer knitted fabric is produced by using Polyester c(30s) and Cotton (30s) Combed yarn and dyed using reactive dye. The fabrics are produced with three different sets of loop lengths of 3.90mm/3.68mm,3.42mm/3.30mm, 3.08mm/3.00mm. The density of the fabric samples were maintained as 197 GSM, 221 GSM, and 240 GSM. The comfort properties like absorbency, wicking, wetting, thermal conductivity, thermal resistance and air permeability of the knitted fabric produced with the above mentioned specification were studied. Fastness properties of the fabric with respect to washing, perspiration, rubbing and light have been analysed. The mechanical properties of the multi-layerfabric with respect to bursting and pilling have been analysed. The optimization of the findings has been done using statistical tools.
