Introduction

Friction (DREF) spinning system is an Open-end and/or Core sheath type of spinning system. Along with the frictional forces in the spinning zone, the yarn formation takes place. The DREF spinning system is used to produce yarns with high delivery rate (about 300mpm). Still, it has to gain its importance with the growth along with technical textiles in India. Amongst the spinning systems, DREF provides a good platform for the production of core-spun yarns due to its spinning principle. It offers less spinning tension to the core, and the core will be positioned exactly at the center of the yarn. Due to complete cover of the core filaments, yarns can be produced with required tensile properties by altering the core proportion.

Development of DREF core-spun yarns unveils a path for new products, including high-performance textiles, sewing threads, and in the apparels due to its exceptional strength, outstanding abrasion resistance, consistent performance in sewing operation, adequate elasticity for the stretch requirements, excellent resistance to perspiration, ideal wash and wear performance, and permanent press.
