Description
Technical field
The present invention relates to superfine fibre technical field more particularly to a kind of Novel super-thins based on modified PVA sea-island fibre
Fabric lining.
Background technology
Sea-island fibre is that a kind of polymer is scattered in another polymer, and dispersed phase is in " island " shape in fibre section
State, and parent is then equivalent to " sea " is a kind of state that ingredient is disperseed with fine in terms of the cross section of fiber by another kind at
Subpackage is round as marine there are many island.Its " island " and " sea " ingredient are continuous, intensive in the axial direction of fiber, uniformly divide
Cloth.In process of production, it has the fiber number of conventional fibre, but " sea " ingredient is dissolved away with solvent, then boundling can be obtained
The superfine fibre beam of shape.Sea-island fibre has the characteristic of water suction, and with the reduction of fibre number, diameter attenuates, and Unit Weight is fine
The surface area of dimension increases, and with the increase of surface area, the covering power of fiber increases, and moisture pick-up properties substantially improves.Sea-island fibre
It is soft, comfortable and easy to wear, fabric is made, the core sucting action of capillary can be generated, fabric is made to adsorb more juicy, and can
These moisture are moved into fabric surface, make its evaporation, increase the comfort of dress.
With the reduction of fibre number, diameter attenuates, and the surface area of Unit Weight fiber increases.With the increasing of surface area
Add, the covering power of fiber increases, and moisture pick-up properties substantially improves.Since fiber is ultra-fine, fiber is more soft, and fabric is made, can
The core sucting action for generating capillary makes fabric adsorb more juicy, and can these moisture be moved to fabric surface, makes its evaporation,
Increase the comfort of dress.The diameter of superfine fibre is smaller, and the radius of curvature of fiber is bigger, the scattering light of surface reflection
The ratio accounted for is bigger, makes the tone of fabric surface than milder.It is processed by the design of fabric, utilizes sea-island fibre extreme
Thin fibrillation feature, can obtain many special Fabric Styles, such as Hair style, Glove suede, super high density fabric.This kind fabric
It can be widely used in clothes, dress ornament field, luggage, indoor article and industrial field etc..The Glove suede developed using sea-island fibre
Many performances of pile fabric are simultaneously no less than natural suede, and natural suede is even better than there are many performance.Its fabrics feel soft,
Drapability is good, and quality is frivolous, is the half of corium, can be made into different-thickness and the fabric of weight, thus sea-island fibre fabric is standby
It is popular.
Sea-island fibre is the abbreviation of islands-in-sea bicomponent fibre, it is distinguished 2 kinds of fibre-forming polymers using composite spinning technology
As " island " and " sea " component, melt spinning is carried out by different proportionings, then utilizes this 2 kinds of components to certain chemical solvent
Different dissolubilities, dissolve " sea " component and leave " island " component i.e. composite ultrafine fiber.Added with rear according to marine facies polymer type
The difference of work technique, sea-island fibre are divided into the molten sea of solvent (benzene decrement method) and hydrolyze exfoliated (alkali decrement method).Benzene subtracts
Amount method dissolves marine facies using organic solvents such as toluene, and there are the recycling of solvent, the recycling of sea component and superfine fibres
The various problems such as the removal of upper trace solvent；Alkali reduction is using thermokalite hydrolysis stripping marine facies, though it avoids using organic molten
Agent, reduces environmental pollution, but there are still the recycling of hydrolysate and and the various aspects such as processing of spent lye ask
Topic.To solve problem of environmental pollution of the sea-island fibre when removing marine facies from source, this project plans water-soluble polymer slice
For the marine facies of sea-island fibre, hot water dissolving's marine facies are recycled, superfine fibre is prepared.Wherein, polyvinyl alcohol (PVA) has excellent
Good 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 recognized
It, can be complete by single microorganism in nature or symbiosis population to be a kind of really biodegradable synthetic polymer
CO is generated after degradation2And H2O is a kind of most potential environment friendly material.Therefore, as can PVA is used as sea-island fibre
Water-soluble marine facies, it is expected to the problem of environmental pollution that traditional sea-island fibre benzene decrement is brought with Alkali reduction is thoroughly solved from source.But
It is that the melting temperature of polyvinyl alcohol is less than decomposition temperature, and most polyvinyl alcohol spinning uses wet spinning technology.This work
Skill is only used for the product of one pack system, such as a kind of preparation method of sea-island fibre disclosed in CN106702530A, utilizes poly- second
The one pack system of enol produces sea-island fibre, but cannot be used for composite spinning product.Therefore, it is necessary to which polyvinyl alcohol is carried out
It is modified to 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 DEG C) are sufficiently close to decomposition temperature (200-220 DEG C), 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 is the deciding factor for hindering PVA to be used for sea-island fibre water solubility marine facies.
