Peptide Fiber – New Textile Material

Organic Raw Materials

Peptide fiber is primarily produced from bio-based polyvinyl alcohol and collagen. To begin with, bio-based PVA is plant-derived, fermented, decomposed and polymerized from crop straw and molasses leftover from sugar production. Furthermore, it features outstanding biocompatibility and full biodegradability with little environmental impact, and is widely used in medical sutures and dialysis supplies.

In contrast, collagen is a high-molecular polymer extracted from animal protein, mainly processed from pig and cow hides, and possesses superior toughness and elasticity.

y combining these two raw materials, the fiber gains organic feedstock sources. In addition, a series of sophisticated chemical reactions during production build exclusive peptide bond structures, which endow peptide fiber with excellent physical and chemical properties.

Organic Production

Peptide fiber also prioritizes environmental protection and sustainability throughout its manufacturing with advanced eco-friendly spinning technologies. Besides, pollutant emissions are rigorously regulated to comply with both domestic and international environmental requirements at every production stage.

Specifically, wet spinning is adopted in production. First, the two raw materials undergo hydrolysis to break down collagen into small molecules and collagen peptides before blending with dissolved polyvinyl alcohol. Moreover, only mirabilite is used as the auxiliary agent during spinning, causing zero pollution to the environment.

In comparison, conventional blends of PVA with milk protein or soybean protein require formaldehyde crosslinking treatment. Differently, peptide fiber applies a formaldehyde-free process thanks to the triple-helical long-chain structure of collagen, which wraps around the surface of polyvinyl alcohol. Consequently, the finished fiber is harmless and safe for human contact.

Furthermore, peptide fiber features a natural milky white base color, and plant-based dyeing is available during its production.

Organic Biodegradable

As an innovative organic fiber, it’s boasts prominent biodegradability. In addition, it can be fully decomposed by microorganisms within a short period under natural conditions at the same degradation rate as cotton, leaving no pollution to the ecosystem.

Thanks to this merit, peptide fiber enjoys promising application prospects in eco-friendly industries. Furthermore, it can serve as an ideal sustainable substitute for non-biodegradable conventional materials across textiles, medical supplies and other sectors to cut down environmental contamination.

Features of Peptide Fiber

High Tenacity: Its tensile strength approaches that of polyester.
