Mechanical Performance of Hemp-Containing Denim Fabrics with Core-Engineered Weft Yarns
Summary
A Çukurova University researcher and a Turkish textile company tested 11 industrially made 3/1 denim twills. Five had 100% cotton warp and six a 69/31 cotton/hemp warp; wefts were rigid, elastane core-spun or dual-core (PET/PTT plus elastane). All were measured after the mill's standard finishing wash. Cotton-warp fabrics were stronger in the warp direction (855 N on average against 672 N for hemp-warp), but in the weft the two groups were alike (404 N against 413 N). Dual-core wefts gave the highest tear strength (62 N warp, 57 N weft on average) and rigid wefts the lowest warp tensile strength. Tensile and tear strength were barely related. The authors conclude hemp content alone does not decide performance; warp blend, weft design and compactness act together. Limits: commercial samples, no full factorial design, and no standard deviations kept.

Why it matters for Egyptian factories
European denim brands are adding hemp to lower the footprint of their jeans. For Egyptian denim mills considering hemp blends, the study shows where strength is lost and how weft choice can make up for it, using real mill fabrics rather than lab samples.
