SILK PROTEIN FIBER ► 

Silk Protein Fiber is a novel biomaterial fiber created by integrating high molecular technology, chemical fiber spinning technology and biotechnology.

It is produced by blending silk protein (Protein from silk pupa) with natural cellulose and then processing it using advanced technology. During the processing, the protein is concentrated on the surface of the fiber, forming a core-sheath structure of protein fiber.

This fiber has a lightweight and airy appearance similar to silk and a fine, soft touch akin to cashmere, providing more options for the design and development of high-end textiles and clothing.

Silk have been used in traditional Chinese medicine for over a thousand years. Modern research shows that silk are highly nutritious. The high-quality protein extracted from silk, known as silk protein fiber, is composed of 18 different amino acids. The content of these 18 amino acids in silk protein fiber is above 15 mg/g, with serine, threonine, tryptophan, and tyrosine being particularly beneficial for the skin, offering special skin-care benefits.

2. Breathable and Comfortable

From a molecular structure perspective, silk protein fiber contains -COOH, -NH2, and -OH groups, while cellulose contains -OH groups. These are all hydrophilic groups that act as natural moisturizing factors. Electron microscope observations show that the surface of silk pupa protein fiber is not smooth but has numerous micro-fine grooves. The cross-section is irregularly elliptical or waist-shaped, with cavities inside and cracks at the edges.

These grooves, cavities, and cracks create a good capillary effect, which quickly absorbs and disperses moisture and sweat from the skin surface to the outer layer of the fabric. This makes it an excellent moisture-wicking and breathable fiber, with a moisture absorption rate of nearly 13%, classifying it as a "breathing fiber." When used in fabrics and clothing, it maintains the skin's water-oil balance, nourishes the skin, and keeps it dry in summer.

3. Skin-Caring and Health-Promoting

Fatigue Reduction

Silk protein fiber can break down free radicals produced by the human body, reducing skin fatigue and reinforcing the youthful state of skin cells.

Restoring Skin Vitality

Amino acids, which are essential components of collagen, promote the production of dermal collagen and serve as a source of skin elasticity. They replenish collagen in the skin, restoring its vitality. Serine and threonine, in particular, promote cell metabolism, accelerate wound healing, and prevent skin aging.

Anti-Aging

Silk protein fiber can delay skin oxidation, maintain the activity of epidermal cells, and slow down skin aging.

UV Protection

The tryptophan and tyrosine in silk protein fiber can absorb ultraviolet rays, effectively protecting the skin from sun damage. Alanine can prevent sunburn and reduce hemoglobin levels, which is beneficial for preventing skin itching and other dermatological issues.

Environmental and Health Benefits

Using high-quality animal protein and pure natural plant fibers, the main components of silk protein fiber are amino acids (Amino acid), carbon (C), hydrogen (H), and oxygen (O). The waste from these fibers naturally degrades under sunlight and water, posing no harm to humans or the environment. It is a pure, natural, and comfortable green textile material.

Vibrant Dyeing

The product is easy to dye, with uniform, vivid, and soft-gloss colors that remain bright after multiple washes.

Wide Range of Applications

Silk protein fiber can be spun purely or blended with cotton, wool, linen, polyester, etc., to produce yarns of various specifications such as 30s, 40s, 60s, 80s, and 120s. It is the best choice for making high-end clothing fabrics, T-shirts, underwear, textiles, bedding, and high-end decorative items.

Fabrics made from silk protein fiber overcome the weaknesses of silk fabrics, such as fragility, poor colorfastness, shrinkage, wrinkling, yellowing, and brittleness when exposed to strong alkalis. They combine the advantages of silk and biomaterial fibers, including bright and soft colors, moisture-wicking and breathability, good drapability, and excellent wrinkle resistance.

Fabrics made from silk protein yarn meet the future trends in clothing, which include being lightweight, airy, comfortable, textured, functional, environmentally friendly, and health-promoting.
