Comfort analysis of structurally modified polyester/PVA yarns produced through DREF spinning system

摘要

The structurally modified friction spun yarn fabric by using polyester as a sheath material and PVA is used as a core material. The processing of fabric to dissolve the core and making the yarn structure as hollow. Thus a fabric with hollow polyester yarn is produced. The various comfort characteristics of the fabric were tested and the results were compared between before and after dissolving PVA core component fabric. The various comfort characteristics going to test are Air permeability, Thermal conductivity, Wicking, Tensile strength, Moisture management test. All the above mentioned tests were to be carried out as per the standards testing procedures. Due to the variation in yarn structure that is the hollowness of the yarn, the characteristics like Air permeability, Water vapour permeability and resistance to flow of heat are better than the normal fabric. Thus comfort characteristics of the fabric are better than the normal polyester fabric.
