MECHANICS OF WOVEN FABRICS.PART1.THEORETICAL INVESTIGATION OF WEAVABILITY LIMIT OF YARNS WITH THICKNESS VARIATION.

Theoretical maximum weavability relationships of fabrics woven from regular warp ends and variable thickness filling yarns are derived by developing a local geometry where the thick filling place is interlaced with warp ends and where the warp yarn is interlaced with thick and thin yarns. From this, geometric relationship, a local weavabi..

POLYPROPYLENE. PART 1. STRONG BACKING IN CARPETS.

Woven polypropylene (PP) began to replace jute in primary carpet backings during the early 1960s. James Lees Carpet Company applied for the first patent using PP because of its processability, low cost, stability in sourcing, and good physical properties. PP ribbon yarns for primary carpet backing are produced by slit-die extrusion. In 19..
