Types And Characteristics Of Viscose Fiber

< p > viscose is an ancient variety of < strong > a href= "http://cailiao.sjfzxm.com/Matertial/show/default.aspx" > fiber > /a > /strong > variety, also known as rayon and viscose filament.

As early as the late nineteenth Century, Crowe, Bevan and Beadle first made cellulose sodium sulfonate solution from cotton. Because the viscosity of the solution was very large, it was named "viscose".

When the viscose is acid, the cellulose will re precipitate.

According to this principle, in 1893, it developed into a method of making cellulose fibers, which are called viscose fibers.

By the early twentieth Century, Miller invented a kind of coagulation bath consisting of dilute sulfuric acid and sulphate, and achieved the industrial production of viscose fiber.

< p > viscose fiber belongs to regenerated cellulose fiber, which can be divided into ordinary type, strong type and high performance type.

It is made of natural cellulose as raw material, and is made of soluble cellulose sulfonate through alkalization, aging, sulfonation and so on. It is made from viscose and dilute lye, and is made by wet spinning.

By using different raw materials and spinning process, ordinary viscose fiber, high wet modulus viscose fiber and high strength viscose fiber can be obtained.

Ordinary viscose fiber has general physical and mechanical properties and chemical properties, and is also divided into cotton, wool and filament type, commonly known as artificial cotton, artificial wool and rayon.

High wet modulus viscose fiber has high polymerization degree, strength and wet modulus.

The fiber density per unit line density in wet condition can withstand 22.0cN load, and the wet elongation at this load does not exceed 15%.

High strength viscose fiber has high strength and fatigue resistance.

Viscose fiber is one of the earliest chemical fibers that have been put into industrial production.

Because of its good moisture absorption and comfortable wearing, it has good spinnability and is often blended with cotton, wool or all kinds of synthetic fibers. It is used for all kinds of < a target= "_blank" href= "http://www.91se91.com/" > strong > clothing < /strong > /a > and decorative "a target=" _blank "_blank".

High strength viscose fiber can also be used for tire cord, conveyor belt and other industrial supplies.

Viscose fiber is a widely used chemical fiber.

[viscose fiber has good hygroscopicity. Under general atmospheric conditions, moisture regain is about 13%.

After moisture absorption, it is significantly expanded and the diameter is increased to 50%. Therefore, the fabric feels hard and has high shrinkage after launching.
