Abstract

The invention discloses high wet modulus viscose fiber leather base cloth and a production process thereof. High wet modulus viscose fibers are adopted in the leather base cloth to serve as warps and wefts to be knitted into high wet modulus viscose fiber grey fabric, and the grey fabric is dyed and finished to obtain the high wet modulus viscose fiber leather base cloth. High-grade artificial leather manufactured by means of the leather base cloth is extremely high in strength, thickness, hand feel and other genuine leather senses, good in quality, high in air permeability, good in heat retention property, convenient to clean, healthy and environment-friendly. The production process comprises the steps of dyeing, drying, gigging, shearing, width stretching and the like, wherein dyeing comprises the steps that (1) liquid-state enzyme desizing is carried out: 10g high-temperature enzymes are added to each liter of water to modulate the solution amount, the temperature is 70-80 DEG C, the lathe speed is 90-110 m/min, and desizing is carried out twice; (2) water washing is carried out: the temperature is 30 DEG C, the lathe speed is 120 m/min, and water washing is carried out twice; (3) dyeing is carried out; (4) softening is carried out: 15-17g BM-6 softening agents and 4-6g 602 softening agents are added to each liter of water to modulate the solution amount, the temperature is 40-45 DEG C, the lathe speed is 100 m/min, and softening is carried out twice.

Description

A kind of koplon leather base cloth and production technology thereof
Technical field
The present invention relates to textile field, be specifically related to base substrates and the production technology thereof of the leather goods such as artificial leather.
Background technology
Leather base cloth is for manufacturing the base substrates of dermatine, raising along with people's living standard, demand to leather wear is increasing, the quantity of natural leather can not meet people's demand far away, add the price of natural leather costliness, allow again common wage-earners hang back, therefore, inexpensive dermatine arises at the historic moment.
Common artificial leather (PU leather) is general adopt take the first generation be 20 beginnings of the century as the common viscose fiber that solves shortage of cotton and emerge be graticule, the grey cloth being made into makes common leather base cloth after dyeing and finishing, finally makes artificial leather fabric.Because first generation common viscose fiber grey cloth fabric intensity is lower, wet fastness is poor, and elasticity is also poor, the easy wrinkle of fabric and difficult recovery; Acidproof, alkali resistance is also poor.The artificial leather fabric brute force made from this is low, too thick and heavy, and elasticity is little, easy wrinkle, and kishke feel is poor, and alkali resistance is poor, and washing requires strict, is not easy to washing, can not reach the Expected Results that people pursue cortex clothes, can not meet people for the pursuit of fashion.
Second generation regenerated fiber is the koplon that starts to realize suitability for industrialized production the 1950's, compares with first generation common viscose fiber, has the following advantages:
(1) intensity is large, and this fiber every spy of unit line density (tex) under hygrometric state can bear 22.0 lis of newton (cN) load of (being equivalent to 2.5 grams of per dawn), and the wet expansion under this load is no more than 15%.
(2) washing shrinkage is little, and washing shrinkage is less 1 times than common viscose fiber.
(3) good springiness, the cloth of making is whole compared with plate, and wrinkle resistance is better than common viscose fiber.
(4) alkali resistance is good, is in the suds the selection of the washing agent such as soap is required to reduce.
Therefore the leather made from koplon, also will have better fabric quality, and its brute force, thickness, elasticity are better, and corium feel is better.But the production technology of koplon leather base cloth is also different from the production technology of common viscose fiber leather base cloth, in desizing, in liquid enzyme and soft technique, the kind of softener, quantity are selected, and in producing, temperature control all plays conclusive impact to performance indications such as the brute force of the leather cloth of finally making, feels.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of koplon leather base cloth and production technology thereof, the koplon artificial leather made from this leather base cloth, and the kishke feels such as its brute force, thickness, feel are extremely strong, quality better; Gas permeability is strong, warmth retention property good, is convenient to washing, health environment-friendly.
The present invention is achieved through the following technical solutions:
A leather base cloth, is characterized in that: adopt koplon as warp thread, weft yarn, be made into koplon grey cloth, grey cloth makes koplon leather base cloth after dyeing and finishing; The thickness of described leather base cloth is 0.50-0.52 mm; More than ultimate strength 350N/5cm.
A production technology for koplon leather base cloth,
Grey cloth requires: koplon grey cloth cloth cover non-cracking, more than ultimate strength 360N/5cm;
Processing step comprises:
One, dyeing:
Capital equipment: autojig
1. liquid enzyme destarch: add 10g high temperature enzyme modulation liquid measure, 70~80 ℃ of temperature, the speed of a motor vehicle 90~110m/min, destarch 2 roads by every premium on currency;
2. washing: 30 ℃ of temperature, speed of a motor vehicle 120m/min, washes 2 roads;
3. dyeing;
4. softness: by every premium on currency, add 15~17g BM-6 softener and 4~6g602N softener modulation liquid measure, 40~45 ℃ of temperature, speed of a motor vehicle 100m/min, walks 2 roads;
Two, dry;
Three, napping;
Four, cropping;
Five, widen.
The present invention compared with prior art, has following obvious advantage:
First generation common viscose fiber grey cloth, through dyeing and finishing processing, makes common leather base cloth, thickness at present for 0.48-0.50mm,ultimate strength 150-160between N/5cm, the artificial leather thickness of making 0.8mm,powerful between 260-270N/5cm,3 grades of left and right of expert evaluation feel; The acid-fast alkali-proof of artificial leather is poor simultaneously, and washing requires strict, is not easy to washing.
The present invention adopts koplon grey cloth, through dyeing and finishing processing, make koplon leather base cloth, thickness is 0.50-0.52 mm, between ultimate strength 180-200N/5cm, and the high-grade koplon artificial leather thickness 0.8mm making, powerful more than 350N/5cm, expert evaluation feel reaches 1 grade, and its kishke feel is extremely strong, quality better; Gas permeability is strong, wrinkle resistance good, and warmth retention property is good; Alkali resistance is good, is in the suds the selection of the washing agent such as soap is required to reduce, and is convenient to washing, health environment-friendly.
