The characteristics and identification methods of viscose, modal, Lyocell.
Author: China popular fiber trends
Viscose fiber, Tencel, modal of the three kinds of fibers and what is the difference? From the three kinds of fiber production process, production characteristics, fabric characteristics, application areas for you to introduce four:
A: production process
(viscose viscose fiber)
From natural cellulose alkalizing and alkali cellulose, and carbon disulfide formation of cellulose xanthate, dissolved in dilute lye in the viscous solution obtained by wet spinning of viscose rayon said, and a series of processing into viscose fiber. Viscose is the first kind of regenerated cellulose fiber production and processing.
modal
It is a kind of regenerated cellulose fiber with high wet modulus, which is made by the special spinning technology.
Lyocell
The formation of the natural plant fiber after crushing the pulp as raw material, through organic solvent spinning method. Advanced technology makes the solvent recovery rate as high as 99.7%, energy saving, environmental protection, and sustainable development.
Two: production characteristics
(viscose viscose fiber)
In the production process will release carbon disulfide and hydrogen sulfide, physiological and harmless, biodegradable.
modal
The production process is pollution-free, physiological and biological degradation.
Lyocell
The production process has no chemical reaction, the solvent is nontoxic, the waste can be biodegraded, the production process is simple, the petroleum resource can be saved, and the environmental protection requirements can be met.
Three: fabric features
(viscose viscose fiber)
Has good moisture absorption, consistent with the human skin physiological requirements, the fabric is soft, smooth, breathable, easy to electrostatic, anti UV, wearing comfortable, easy dyeing, dyed with bright color, good color fastness, has good spinnability.
modal
Feel soft, smooth, bright color, good color fastness, fabric cloth feels very smooth, shiny, drape are better than those of cotton, polyester, viscose, synthetic fiber having strength and toughness, with silk luster and feel, the fabric with anti wrinkle and free hot, water absorption and good air permeability.
Lyocell
Many excellent properties of natural fiber and synthetic fiber with natural luster, feel smooth, high strength, no shrinkage, and moisture permeability, good air permeability, soft, comfortable, smooth and cool, good drapability, durable and durable.
Four: application areas
viscose
Short fiber can be pure spinning, can also be blended with other textile fibers, suitable for making underwear, outerwear and a variety of decorative items. Filament fabric is thin, except for the material can also be woven quilt and decorative fabric.
modal
Knitted fabric is mainly used in the production of underwear, but also for sportswear, casual wear, shirts, senior apparel fabrics, etc.. Blended with other fibers can improve the stiffness of pure modal product.
Lyocell
Covering all areas of textile, cotton, wool, silk, hemp products, or knitting or weaving field can produce high-quality high-grade products.
Then the focus is coming
How to identify it?
A. longitudinal morphology
viscose
Smooth, uniform, with a few clear stripes
Undefined
modal
The surface smooth, shiny, with a groove intermediate (smooth surface, Lenzing modal); gloss, fuzzy or intermittent groove groove, vertical stripes is not obvious close to Lyocell (formotes modal)

Lyocell
Smooth surface

B. cross section
viscose
Serrated, with a core layer, there are many different sizes of pores in the cross section

modal
Type C or dumbbell type

Formotes modal
Irregular shaped (formotes modal)

Lyocell
Round or nearly round
