An investigation of the structure and Properties of jet ring spun and other Types of compact yarns

Abstract

Compact spinning which is an emerging staple yarn manufacturing newlineTechnology is challenging the traditional ring spun technology for use in both newlinewoven and knitted fabrics The driving force for this is the production of yarn newlinewith less hairiness and higher strength Many types of compact spinning newlinesystems were launched and it is imperative that their potential should be newlineinvestigated for the benefit of the industry The prime objectives of the study newlinereported in this thesis are to investigate the effects of using different number newlineof air jet nozzles built from different materials on jet ring spun compact yarn newlinecharacteristics a comparative study of the other types of compact yarns newlineincluding the elite and rocos with a view to studying their differences and to newlineinvestigate the low stress mechanical properties of plain weft knitted fabrics newlineknitted from conventional and compact yarns newline newline
