Discover Peptide Fibers: The New Textile Material
Date: 2024/12/30 By: Winnie
In driving sustainability and innovation in the industry, the emergence of peptide fibers is slowly changing the textile industry. Blending science and fashion to create fibers that are not only environmentally friendly but also have superior performance—peptide fibers. Peptide fibers combine the elegance of natural materials with the advanced features of modern technology, which you can explore below.
What is Peptide Fiber?
Peptide fiber is a new type of organic, bio-based, artificial protein fiber in the textile field, rich in 18 kinds of amino acids, with bio-based polyvinyl alcohol and collagen as the main raw materials, after scientific methods of organic combination made of green. Biodegradable. This man-made protein fiber, which has the same touch as mulberry silk and cashmere, is different from milk fiber and soybean fiber and has the highest protein content of man-made fibers on the market.
Peptide Fiber - raw material organic
The raw materials of peptide fibers are mainly bio-based polyvinyl alcohol and collagen.

Bio-based polyvinyl alcohol is mainly from plant sources and is produced by fermentation, decomposition, and polymerization of straw and molasses from cane sugar waste liquid. Bio-based polyvinyl alcohol is highly biocompatible, biodegradable, and environmentally friendly and is commonly used in medical surgical sewing threads and dialysis materials. Collagen, on the other hand, is a polymer substance extracted from animal proteins, which is made from pig skin and cow skin and has excellent toughness and elasticity.
The combination of these two raw materials not only ensures that the peptide fiber is made from organic raw materials but also forms a unique peptide bond structure through a series of complex chemical reactions during the subsequent processing, giving the peptide fibers excellent physical and chemical properties.
Peptide Fiber-Producing Organic
Peptide Fibers pay equal attention to environmental protection and sustainability in its production process, adopting an advanced, environmentally friendly fiber production process. Strict control of pollutant emissions during the production process ensures that every step meets national and international environmental standards.

Spinning is a wet spinning process. The first two fibers will be hydrolyzed, collagen will be dissolved into small molecules and collagen peptide state, and then combined with the dissolved polyvinyl alcohol. In the spinning process, only an additive—manganese—is used; the environment will not cause pollution.
Traditional mixtures of polyvinyl alcohol and other proteins, such as milk protein and soy protein, need to be treated with formaldehyde for hydrolysis, while peptide fibers use a non-formaldehyde process. This is related to the morphology of collagen. The long triple helix chain of collagen is combined with polyethylene and is wrapped around the surface, so it is very safe for the human body.
Peptide fiber color is milky white, a very natural color; peptide fiber in the production process can also line plant dyeing.
Peptide fiber - degrading organic
As a brand-new organic fiber, peptide fibers have excellent degradability. In the natural environment, peptide fiber can be completely decomposed by microorganisms in a relatively short period of time (the same degradation rate as cotton) without causing any pollution to the environment.
This feature makes peptide fiber a broad application prospect in the field of environmental protection. Whether in the textile, medical, or other fields, peptide fibers can be used as an ideal environmentally friendly material to replace traditional non-biodegradable materials in order to reduce environmental pollution.
Characteristics of Peptide Fiber
- High strength: has a strength close to that of polyester;
- Skin-friendly: Like our skin, the fiber surface is rich in 18 amino acids.
- Moisture-absorbing and quick-drying: the fabric interwoven with peptide fiber is not only moisture-absorbing and quick-drying but also non-sticky.
- Antibacterial: tested peptide fiber has a strong antibacterial function.
- Smooth: close to the feel of cashmere and silk, but easier to take care of;
- Easy care: not easy to pill or deform.
- Biodegradable: the only biodegradable polyester fiber on the market.

Peptide fibers have a wide range of applications and can be well interwoven with various types of fiber blends or pure spinning. Applications in clothing, medical care, home textiles, personal care, and other fields open up unlimited possibilities. For example, due to its biocompatibility and hygienic properties, it can be used for wound dressing, medical uniforms, and pressure garments.
