Description
Technical field
The present invention relates to a kind of simple for process, less energy consumption, production cost is low, and fiber is secured, smooth with composite for base fabric,
Soft, surface style is fine and smooth, meets the Compound Fabric of the super fine denier viscose fiber and Lyocell fibers that are transparent after water infiltration
And its preparation process.
Background technique
Viscose viscose fiber is that plastic fiber molecule of laying equal stress on is extracted from natural lignose using " wood " as raw material
Obtained from cellulose fibre, the hygroscopicity of viscose fiber meets the physiological requirement of human skin, have it is smooth it is nice and cool, ventilative,
The features such as antistatic, antiultraviolet.Essence with cotton, the quality of silk.It is genuine plant fiber, derived from day however is better than day
So.
Viscose rayon category cellulose fibre.It is with natural fiber (wood-fibred, cotton linter) be raw material, through alkalization, aging,
Soluble cellulose xanthate is made in the processes such as sulfonation, is re-dissolved in sig water and viscose glue is made, and is made through wet spinning.Using
Different raw materials and spinning technique, can respectively obtain common viscose fiber, and koplon and high-tenacity viscose glue are fine
Dimension etc..Common viscose fiber has general physical mechanical property and chemical property, and divides cotton, wool type and long wire type, is commonly called as
Synthetic cotton, man-made hair and artificial silk.The koplon degree of polymerization with higher, strength and wet modulus.This fiber
The every spy of unit line density can bear the load of 22.0cN under hygrometric state, and the wet expansion under this load is no more than 15%, master
There is polynosic.High tenacity staple fibre strength with higher and fatigue performance.
Viscose rayon can be divided into common viscose fiber, koplon, and strong viscose rayon and modified viscose glue are fine
Dimension.In strong viscose rayon, dry strength is more than that the long filament of 30.0cN/tex claims high-tenacity fibre；Title more than 38.0cN/tex is super
High-tenacity fibre；Two HHT higher high tensile silk of title more than 44.1cN/tex；Three HHT higher high tensile silk of title more than 48.5cN/tex；More than 53.0cN/
The four HHT higher high tensile silk of title of tex.In high performance viscose, the higher fiber of elasticity modulus under hygrometric state claims polynosic fine
Dimension, also referred to as high-wet-modulus fibre, China claims polynosic, referred to as rich fine.Wet modulus is between common fiber type and polynosic
Between fiber, but collude with the lesser fiber of intensity, brittleness with higher, claims modified form high-wet-modulus fibre.
The breaking strength of common viscose fiber is smaller than cotton, about 1.6~2.7cN/dtex；Elongation at break is greater than cotton, is
16%~22%；Wet strong decline is more, and about dry 50% by force, hygrometric state elongation increases about 50%.Its modular ratio cotton is low, in Smaller load
Under be easily deformed, and elastic recovery is poor, therefore fabric is easy elongation, poor dimensional stability.Rich fine intensity is especially wet
Higher than common viscose glue by force, elongation at break is smaller, and dimensional stability is good.The wearability of common viscose glue is poor, and rich fibre then has
Improved.The chemical composition of viscose rayon is similar to cotton, thus it is more alkaline-resisting without acidproof, but alkaline-resisting acid resistance is poor compared with cotton.It is rich
It is fine then have good alkaline-resisting acid resistance.The dyeability of same viscose rayon is similar to cotton, and dyeing chromatography is complete, and dyeability is good
It is good.Furthermore the thermal property of viscose rayon is also similar to cotton, density close to cotton be 1.50~1.52g/cm3。
Producing plant fiber Compound Fabric with most of non-woven cloth factories relatively that is, will be fine using composite dry process
Dimension by mechanical carding networking, then carried out again with base fabric it is compound, there are the shortcomings that are as follows: product is rougher, fiber and base fabric
Compound insecure, overall surface style is not fine and close.
The Compound Fabric that the existing compound cloth apparatus of wet type is produced can generate quality (such as smoothness, flatness, the removing of cloth
Intensity, wear-resistant strength etc.) in the width direction generate consistency difference phenomenon.
Summary of the invention
It is fine it is an object of the invention to rougher in order to solve Compound Fabric product prepared by existing composite dry process
Dimension is compound insecure with base fabric, and overall surface style is not fine and close；Wet type Compound Fabric quality such as smoothness, flatness, removing is strong
Degree, wear-resistant strength etc., lead to the problem of the phenomenon of consistency difference in the width direction, and provide a kind of simple for process, energy consumption
Few, production cost is low, and fiber is secured, smooth with composite for base fabric, soft, has water suction, water lock in conjunction with Lyocell fibers
The characteristics of, the super fine denier viscose fiber of surface style exquisiteness and the Compound Fabric and its preparation process of Lyocell fibers.
