Abstract
The use of industrial fabrics is increasing due to their wide range of applications in agriculture, civil engineering, protection and safety, the automotive industry and transportation, Storage and packaging, medical and ecological sectors, sports and recreation. Special fibres and yarns with specific properties are being selected for producing these special fabrics. Woven fabrics are preferred as industrial textiles in situations where the requirements of fabric properties demand high strength and elongation uniformity, dimensional stability and a fairly good resistance to abrasion. The weaving process ensures high utilization of the strength characteristics of the initial fibrous material from which the fabric is manufactured. However, the weaving conditions for new yarns and complex fabric structures pose new challenges for weavers. Understanding yarn behaviour during weaving to achieve high loom shed efficiency and desired fabric quality has been a subject of great interest to weaving technologists. This chapter deals with the weavability of industrial yarns with reference to yarn quality and weaving performance. The term weavability refers to the relative weaving potential of yarns to sustain loom stresses to produce the best possible weaving performance. The weavability of a yarn is largely influenced by the quality of grey yarn and the treatment it receives in the process of sizing. Among various yarn quality parameters, yarn strength, yarn extension and their variation are the most important yarn properties influencing predominantly the warp breakage rate. Abrasion resistance and yarn hairiness are other important yarn properties which significantly affect the performance of yarn during weaving. The study of weavability also deals with fibre damage and structural distortion of yarns during weaving. The analysis of weavability therefore helps to preserve the strength characteristics of the parent yarn when weaving industrial textiles.
