DESCRIPTION
EuroFibers has co-developed a technology that more than doubles the abrasion resistance and tear strength of cotton. This patent pending innovation of cotton reinforced with a negligible percentage of Dyneema® is a break trough in the cotton industry. Besides the increase in wear resistance, the technology also significantly improves tensile strength and tear resistance without adding a great amount of cost. Levi Strauss & Co. has recently launched an original Levi’s® 501 reinforced with Dyneema®.

// Tear resistance results with cotton
Comparing to 100% Cotton Fabrics: • Adding 2% Dyneema® will improve
Tear strength with 65% • Adding 10% Dyneema® improve
tear strength with more than 300% Comparing to 35/65% PES/Cotton: • Adding 10% Dyneema® will give
comparable results

// Results with cotton
• 2% Dyneema® staple fiber into Cotton: – 50% increase in strength of yarn. – 65% increase in tear resistance of woven (Jeans) fabric – 100% increase in Abrasion resistance
• Identical performance with 3 x less Dyneema® can be achieved compared to using Polyester re-enforcement: – 100% cotton-touch & better moisture absorbance – No need for double dyeing
• No reduced strength of cotton after Proban® treatment
• Levi’s Strauss & Co. launched Levi’s 501 reinforced with Dyneema®
