Regenerated Collagen Fiber

MC 8222-01

NATURALS

Textile fibers made from collagen. Collagen fibers have a very smooth surface and an inherent softness. They also readily absorb and release humidity, balancing moisture. This absorbent behavior aids in dye uptake and results in deep colors. Other properties include bacteria growth inhibition and a Limited Oxygen Index (LOI) of 36, which can be indicative of low combustibility. For comparison: wool, considered to be a naturally fire retardant fiber, has an LOI of 25 (higher scores are better). Untreated cow hides are solubilized, stabilized, and non-collagen components are removed. The solution is then concentrated and wet spun into filaments. After drying, the filaments are cut into staple fibers and crimped to add texture. The fibers are offered in bales of 100 kg (220 lb.). Multiple fiber cut lengths are available: 38 mm, 51 mm, 76 mm, 89 mm (1.5 in, 2 in, 3 in, 3.5 in); custom lengths are negotiable. The fiber is off-white in color. Dyeing and finishing must remain at temperatures under 60 ˚C (140 ˚F) to ensure stability of the fiber. Moisture behavior testing shows the fiber to have slightly higher absorbency volume than cotton and a slower moisture release rate, about double the time from peak moisture to dry. A bacteriostatic property is also demonstrated, with a reduction in the presence of staphylococcus aureus by 50% 18 hours after the initial culture on a blended collagen textile. Odor reduction is also seen, demonstrated by particle reductions in odor causing compounds. Reductions by a 100% polyester nonwoven and a 14% collagen nonwoven are, respectively: ammonia 7% and 95%, acetic acid 20% and 89%, insovaleric acid 24% and 56%. Applications include cosmetic facemasks, accessories, lingerie, base layers, sleepwear, and bedding.
