Abstract
The invention discloses a kind of methods preparing peach face Base fabric using water-soluble poval sea-island fibre, it is woven into peach face institutional framework through tatting or knitting by water-soluble poval sea-island fibre, the preparation of the water-soluble poval sea-island fibre includes the following steps：（One）, water-solubility PVA master batch preparation（Two）, sea-island fibre preparation（Three）, sea-island fibre final finishing.The present invention is compared with traditional PVA, due to reducing fusing point, not only ensure that PVA sea components can be with dystectic PET melt composite spinnings, and can't occur while reaching fusing point PVA decompose the problem of, solve the problems, such as traditional PVA encounter high temperature PET decompose and can not melt composite spinning.
Description
Technical field
The present invention relates to superfine fibre technical fields more particularly to a kind of utilization water-soluble poval sea-island fibre to prepare
The method of peach face Base fabric.
Background technology
Peach face product is the imitation leather fabric developed after artificial suede product, it is thin by one kind that superfine fibre forms
Type fabric.Peach face is a kind of novel slim pile of Superfine Fibre Fabric, it is the tread flaking from artificial suede,
Due to being handled without polyurethane wet, so quality is more soft；Again because its suede is shorter, villus is not almost seen and skin in surface
Skin can but perceive, so that feel and appearance are finer and smoother and unique；The soft elegance of peach face gloss, compared with artificial suede, to disappearing
A kind of novel sense of the person of expense, has been suitble to the consumer psychology of people's curiosity, so that becoming much more popular in the international market quickly.
Dacron ultrafine fiber is the peach face fabric of raw material, because it has the function of as moisture absorption, ventilative, waterproof and silk
Look and feel, soft fabric, rich in gloss, feel slide it is glutinous the advantages that, be widely used in clothes（Jacket, clothing skirt
Deng）, lodge, shoes and hats, furniture decoration ideal material.
Superfine fibre with its high spreadability, it is soft, take comfortable, gloss is soft, have a performances such as good dispersiveness and
People's concern is received, the fields such as clothes, dermatine, construction material, absorption and filtering material are widely used in.Sea-island fibre is sea
The abbreviation of island composite fibre, it, using 2 kinds of fibre-forming polymers as " island " and " sea " component, is pressed using composite spinning technology
Different proportionings carries out melt spinning, then utilizes this 2 kinds of components to the different dissolubilities of certain chemical solvent, dissolves " sea " group
" island " component, that is, composite ultrafine fiber under fractionation.According to the difference of marine facies polymer type and after-processing technology, sea-island fibre point
For the molten sea of solvent（Benzene decrement method）It is exfoliated with hydrolyzing（Alkali decrement method）.Benzene decrement method utilizes the organic solvents such as toluene
Marine facies are dissolved, there are the recycling of solvent, the various aspects such as removal of trace solvent on the recycling of sea component and superfine fibre
Problem；Alkali reduction reduces environmental pollution using thermokalite hydrolysis stripping marine facies though avoiding using organic solvent, there are still
The recycling of hydrolysate and and spent lye the various problems such as processing.
To solve problem of environmental pollution of the sea-island fibre when removing marine facies from source, this project plans water-soluble polymer
Marine facies of the slice for sea-island fibre, recycle hot water dissolving's marine facies, prepare superfine fibre.Wherein, polyvinyl alcohol（PVA）Have
Excellent water solubility, mechanical property, film forming, emulsibility, organic solvent resistance etc. are widely used in weaving, papermaking, timber
The fields such as processing, daily use chemicals, medicine, sewage disposal are a kind of widely used functional high molecule materials.In addition, PVA is considered
It is a kind of really biodegradable synthetic polymer, it can be degradable by single microorganism in nature or symbiosis population
After generate CO2And H2O is a kind of most potential environment friendly material.Therefore, as can PVA is used as the water-soluble of sea-island fibre
Property marine facies, it is expected to traditional sea-island fibre benzene decrement is thoroughly solved from source and problem of environmental pollution that Alkali reduction is brought.But it is poly-
The melting temperature of vinyl alcohol is less than decomposition temperature, and most polyvinyl alcohol spinning uses wet spinning technology.This technique can only
For the product of one pack system, such as a kind of preparation method of sea-island fibre disclosed in CN106702530A, utilize polyvinyl alcohol
One pack system produces sea-island fibre, but cannot be used for composite spinning product.Therefore, it is necessary to after polyvinyl alcohol is modified
It can carry out composite molten spinning.
But PVA is a kind of polyhydroxylated polymer, strong intramolecular and intermolecular hydrogen bonding are formed between hydroxyl makes its fusing point
（200℃）With decomposition temperature（200-220℃）It is sufficiently close to, when with thermoplastic material composite molten spinning, it is easy to due to
Heat transfer between melt and lead to that thermal decomposition occurs for PVA and can not melt composite spinning, therefore spun in sea-island fibre composite molten
Silk field fails to solve the problems, such as this always.Traditional sea-island fibre molding can only be solution-polymerized SBR, such as 105648576 A of CN
Disclosed a kind of PTFE/PVA sea-island fibres and preparation method thereof, belong to solution-polymerized SBR, but cannot achieve and island phase resin
Composite molten spinning, be hinder PVA be used for sea-island fibre water solubility marine facies deciding factor.
Invention content
In view of the deficienciess of the prior art, the technical problem to be solved by the invention is to provide one kind passing through this method
