New Methods of Texturing Polyester/Viscose Blended Yarns by Simultaneous Setting of the Components

Abstract

A two-ply 50/50 polyester/viscose spun yarn was textured by the twist-set-detwist process through simultaneous setting of the components. The setting methods employed were 1) heat-setting plus dry-crosslinking by the use of resins at high curing temperatures, and 2) solvent-setting plus wetcrosslinking by a solution of epichlorohydrin in tetrachloroethane. It is observed that while the mechanical properties and crimp-rigidity values of the yarns produced by the two methods are comparable, method 2 produces yarn with a higher wet retractability and a considerably higher dye uptake.

Texturing of Polyester-Viscose Blended Yarn by Batch and Continuous Processes

“…The average ash content of these dusts was approximately 200/0--a value about the same as that found in leaf and bract samples [12]. Other studies of dusts on elutriator filter media have included measurements of the particle-size distribution of the dusts [1,8].…”

Characterizing a novel method for blending regenerated cellulose structures with polyester filaments

“…1 Polyester/rayon blended yarns exhibit a high strength and good elasticity. [3][4][5][6] The blending process of regenerated cellulose and polyester fibers, done to achieve better properties, is very expensive in the spinning process. 1 Polyester blends with cellulosic fibers are used mainly in the production of shirting, dress goods, light suit fabrics, and coated fabrics.…”

“…They show very good crease resistance and drape compared to pure linen fabrics. 3,4 However, during the 20th century, there have been many attempts to investigate the special properties of these blended yarns. The cellulosic component is most often cotton and rayon staple and, less frequently, flax.…”
