Description
Technical field
The present invention relates to superfine fibre technical field more particularly to a kind of novel island fiber synthetic leather base cloth and its productions
Technique.
Background technology
Fiber synthetic leather is all made of woven fabric, looped fabric in the past, was gradually needled method non-woven cloth later and spun lacing method is non-
Woven cloths are substituted.It is undesirable as synthetic leather product poor flexibility, the surface style of base fabric using woven fabric or looped fabric, it can only
Produce low and middle-grade synthetic leather products；Although having one as the synthetic leather product of base fabric using general acupuncture cloth, spun laced fabric
Fixed artificial leather effect, but fiber is thicker, and the density of base fabric structure is relatively low, is not met by the requirement of medium and high-grade goods；Into
With the progress of superfine fibre manufacturing technology after 21 century, from indefinite island island superfine fiber to the amount for determining island island superfine fiber
Production, the volume production of superfine fibre cause high-end textile development upsurge；The appearance of island superfluorescent fiber PU synthetic leather was the 5th generation
The non-woven fabrics of its three-dimensional structural network of artificial leather is that synthetic leather creates the condition for catching up with and surpassing natural leather in terms of base material.Island
Superfluorescent fiber huge surface area and strong water imbibition act on so that ultra-fine grade PU synthetic leather is provided with the ultra-fine collagenous fibres of pencil
The intrinsic moisture-absorption characteristics of natural leather because regardless of being worn from internal microstructure or appearance tactile impression and physical characteristic and people
Comfort etc. can compare favourably with advanced natural leather.In addition.Island superfine fiber synthetic leather is in chemical resistance, matter
Measure homogeneity, big production and processing adaptability and waterproof, anti-mildew etc. have more been more than natural leather.
Currently, also being developed in succession in the market applied to the non-woven of synthetic leather industry needle point method or spun lacing method island woven fabric
Product, but excellent weak tendency is such as existing for the product itself produced due to needle point method or spun lacing method:Needle point method synthetic leather base cloth
Product has the high splitting of strength good, but the defect of there are needle tracks appearance that is apparent, influencing cloth cover.And spun lacing method synthetic leather
Base fabric cloth cover is closely knit, lines is fine and smooth, flat appearance, but that there are intensity is relatively low, easily peelable, the defect that is easily layered for product.Existing skill
Needle in art pierces spun lacing combination process, i.e., is processed through spun lacing after first pre-needling, can achieve the purpose that not damage base fabric, but exist
The problem that binding force is inadequate, tensile strength is poor.
The default island microfiber synthetic leather main technique form of state is：Island woven fabric → needle-punching substrate → base fabric arrangement → wet method system
Leather → decrement treatment → mill skin oils → PU fittings → resultant Leather.This technology investment is larger, and technological process is long and control is multiple
It is miscellaneous.Mainly its Alkali reduction equipment is complicated, and production difficulty is big, of high cost.Superfine fibre is with its high spreadability, soft, clothes
With comfortable, gloss is soft, there are a performances such as good dispersiveness and receives people's concern, it is widely used in clothes, dermatine, Building wood
The fields such as material, absorption and filtering material.Sea-island fibre is the abbreviation of islands-in-sea bicomponent fibre, it uses composite spinning technology by 2
Kind fibre-forming polymer carries out melt spinning respectively as " island " and " sea " component, by different proportionings, then utilizes this 2 kinds of components
To the different dissolubilities of certain chemical solvent, dissolves " sea " component and leave " island " component i.e. composite ultrafine fiber.It is poly- according to marine facies
The difference of polymer type and after-processing technology, sea-island fibre are divided into the molten sea of solvent（Benzene decrement method）It is exfoliated with hydrolyzing（Alkali
Decrement method）.Benzene decrement method dissolves marine facies using organic solvents such as toluene, and there are the recycling of solvent, sea components to return
The various problems such as removal of trace solvent in receipts and superfine fibre；Alkali reduction is using thermokalite hydrolysis stripping marine facies, though it avoids
Use organic solvent, reduce environmental pollution, but there are still the recycling of hydrolysate and and spent lye processing
Equal various problems.To solve problem of environmental pollution of the sea-island fibre when removing marine facies from source, this project plans water solubility
Polymer chips is used for the marine facies of sea-island fibre, recycles hot water dissolving's marine facies, prepares superfine fibre.Wherein, polyvinyl alcohol
（PVA）With excellent water solubility, mechanical property, film forming, emulsibility, organic solvent resistance etc., be widely used in weaving,
The fields such as papermaking, timber processing, daily use chemicals, medicine, sewage disposal are a kind of widely used functional high molecule materials.In addition,
PVA is considered as a kind of real biodegradable synthetic polymer, can pass through the single microorganism or symbiosis kind in nature
CO is generated after group is degradable2And H2O is a kind of most potential environment friendly material.Therefore, as can PVA is used as island
The water-soluble marine facies of fiber, it is expected to thoroughly solve traditional sea-island fibre benzene decrement from source and be asked with the environmental pollution that Alkali reduction is brought
Topic.But the melting temperature of polyvinyl alcohol is less than decomposition temperature, most polyvinyl alcohol spinning uses wet spinning technology.This
Kind technique 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
The one pack system of polyvinyl alcohol produces sea-island fibre, but cannot be used for composite spinning product.Therefore, it is necessary to by polyvinyl alcohol into
Row is modified could 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℃）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.
