In this study, the different effects of weave structure on comfort properties fabrics and mechanical fiber-reinforced composites were investigated. Fabrics developed using one type material (flax spun yarn) in warp direction three materials (flax, sisal cotton weft directions. Four types weaves (plain, twill, matt mock leno) produced each material. Twelve specimens a sample weaving machine. The...

Botanical cotton trash mixed with lint reduces cotton’s marketability and appearance. During cotton harvesting, ginning, and processing, trash size reduction occurs, thus complicating its removal and identification. This trash causes problems by increasing ends down in yarn formation and thus processing efficiency. The Uster® High Volume Instrument (HVI) and Shirley Analyzer are extensively use...

Abstract Electronic fibers/textiles have great potential for applications in smart wearables due to their excellent flexibility, air permeability, and wearing comfort. However, it is still challenging produce reliable electronic textiles at low cost a large scale. Herein, we report spraying‐spinning process fabricating yarns with stability durability. Cotton sliver, which the raw material spinn...

Compression properties of textile materials are useful for determining fullness, softness, smoothness, and stiffness. In addition, compression parameters have significant influence on fabric hand value quality materials. The present paper reports a study the sublimation printing process change in knitted fabrics (polyester, cotton, cotton/ polyester) intended sportswear manufacturing. For that ...

Africa, both francophone as well as anglophone, has traditionally been an important cotton production base. Cotton produced in Africa is mainly exported by international merchants to Asia, where today almost 80% of world cotton fibre is processed into yarn. Fibre transformation rates in Africa are at a historic low, with only 5% of francophone and 43% of anglophone African cotton being processe...
