Cotton Reinforcement

 Dyneema® makes cotton stronger and more durable

Cotton reinforcement with only a very small percentage of Dyneema®, significantly increases the durability of cotton without adding a great amount of costs. Dyneema® is an ultra strong polyethylene fiber that offers maximum strength with minimum weight. It is up to 15 times stronger than quality steel and up to 40% stronger than aramid fibers on a weight-for-weight basis. Further Dyneema® is resistant to moisture, UV light, and chemicals. Dyneema® is currently used to stop bullets, pull oil tankers, or sail around the world. Dyneema® thus has already built up a solid reputation as the material of choice in bullet resistant vests, high protective textiles, or marine applications. Its properties make Dyneema® the world’s strongest fiber™ and the perfect fiber for cotton reinforcement. If Dyneema® is used for cotton reinforcement, the abrasion resistance and tear strength of cotton of cotton can be substantially improved. Only a 2% addition of Dyneema® to cotton results in a 100% increase in abrasion resistance. Further, adding 2% of Dyneema® increases the tear strength of cotton by 65% and adding 10% of Dyneema® increases the tear strength of cotton by more than 300%.

Cotton Reinforcement with Dyneema® – superior strength and comfort

Dyneema® does not only offer improved durability at only marginally increased costs, but is superior to other cotton reinforcements, like for example polyester, in other aspects. Compared to polyester cotton reinforcement the identical performance can be achieved with 3 times less Dyneema®. Dyneema® offers also benefits in the wear comfort as fabrics retain their natural, cotton-like touch and have better moisture absorbance. Additionally there is no need for double dyeing and, at low Dyneema® percentages, colors are uniform. Dyneema® is further able to improve the heat management properties of cotton.
