What kind of fabric is viscose fiber? Is it harmful to the human body? Is protein fiber protein or cellulose?

Viscose fabrics have the advantages of soft hand feeling, smooth and cool, breathable, anti-static, and gorgeous dyeing. It is one of the earliest cellulose fibers put into industrial production. It belongs to the category of regenerated cellulose fiber fabrics and is not harmful to the human body. Therefore, it is widely used in our clothing, etc. So is protein fiber protein or cellulose? Let's open it to find out!

What kind of fabric is viscose fiber? Is it harmful to the human body?

Viscose fiber is a kind of regenerated cellulose fiber fabric, which is not harmful to human body. It is made of natural cellulose, feels very soft and is non-toxic. Viscose fiber is mainly used in textiles of various types of clothing and decorative items.

Viscose fiber is one of the earliest cellulose fibers put into industrial production.

Viscose fabric has strong anti-static properties and will not feel attached to the body, so it is very smooth and especially suitable for sports wear.

Viscose fiber fabrics have the advantages of soft touch, smoothness and coolness, breathability, anti-static properties, and gorgeous dyeing.

Is protein fiber protein or cellulose?

Protein fiber is a type of protein with a fibrous structure. It is a type of artificial fiber, made from protein extracted from natural materials such as milk, soybeans, peanuts, and corn, dissolved in a suitable solvent.

Protein fiber refers to fibers made from natural protein with properties similar to wool. Wool, silk, etc. are natural protein fibers.

The basic structural unit of protein fiber is amino acid, a macromolecule linked together by amide bonds (peptide bonds).

Industrially produced protein fibers include: milk protein fiber, soybean protein composite fiber, silkworm pupa protein fiber, and nano-antibacterial regenerated protein fiber.

Is silk a protein or a fiber?

Silk is both protein and fiber. Silk is a general term for fabrics made of silk or synthetic fibers, man-made fibers, short silk, etc. The natural fibers contained in silk are mainly silk fibers, which are continuous long fibers solidified by the silk fluid secreted by mature silkworms when they make cocoons. Silk is a protein fiber, which is a high molecular compound containing nitrogen, so silk contains protein fibers.

Silk fiber is one of the earliest animal fibers used by humans, including mulberry silk, tussah silk, castor silk, cassava silk, etc.

Silk is composed of protein fibers, which have good biocompatibility with the human body and are comfortable to wear. In addition, silk protein fibers are rich in many hydrophilic groups such as amine and amino groups, and are porous, which can absorb, retain or emit moisture in the air.
