Description
Technical field
The present invention is the manufacture method of relevant a kind of artificial leather material, the manufacture method of refering in particular to a kind of artificial leather material of superfine fiber non-woven complex intensifying.
Background technology
At present general superfine fibre artificial leather is mostly with the spinning of composite spinning mode, and its fineness can't be lower than 0.015 Denier (Denier), so that when being used in leather surface, can't obtain as the careful fine hair sense as the deerskin.
The superfine fibre artificial leather that makes with the blend spinning mode of tradition and for example, though surperficial have as the careful fine hair sense as the deerskin, strength of leather is very poor.
Consult shown in Figure 1, superfine fiber is via impregnation polyurethane (polyurethane, hereinafter referred to as PU) resin combination, and make artificial leather is known, wherein used superfine fiber, for example No. 152961 case of Taiwan patent announcement (application case number No. 78107985) name is called " the compound ultra tiny non-fiber fabric of similar corium ", its processing procedure as shown in Figure 1, its compound ultra tiny fiber that is to use the 0.8-30 Denier is through comb and parallel cotton fibers prior to spinning, folded cotton, tailor's cushion, condense after containing resin pickup and impregnation PU resin, washing and oven dry, with solvent with in the compound ultra tiny fiber one of composition flush away part, again through grinding and compound ultra tiny fiber Nonwovens and back processing.Its major defect is:
But the ground non-woven of the superfine fiber that this kind is traditional, vertically the percentage elongation difference with horizontal is very big because of it, and especially cross direction elongation is higher, often needs to consider the problem of directionality in the use, and the inapplicable artificial leather of doing.
With the rolling superfine fibre non-woven that gets of liquid drugs injection, its non-woven surface has tangible liquid drugs injection vestige mostly, and interlaminar strength is not high as another, and improper as artificial leather.
Composite spinning and fiber and formed superfine fibre and these various manufacture methods are known technologies.Composite spinning and fiber, generally be to give integrator by squeezing out at least two kinds of compatible fibre-forming polymers, make to generate optionally one of polymer dissolving of fiber, and form microfibre.
In addition, tradition is a known technology by the artificial leather of braided fabric through giving reinforcement, in for example Japanese special fair 4-1113 communique, discloses the technology that the braided fabric that has the above high twist yarn of twisting count 1000T/m to form is used as the reinforcement material.This technology is to adopt tailor's cushion, make when short cellucotton non-woven and being integral of reinforcement cloth and silk, with the reinforcement cloth and silk that suppresses to cause by tailor's cushion damage to Min. be purpose, high strength is proposed and the method for making of the artificial leather of softness.But to adopting tailor's cushion to make short cellucotton non-woven and laminated being integral of reinforcement cloth and silk, bestow the contraction of a little after, make dipping adhere to polyvinyl alcohol again, then the part of part principal fiber is removed in extraction, floods elastic resin again and gets artificial leather.Its main pluses and minuses are:
Since be with make the reinforcement cloth and silk have with the superfine fibre non-woven through giving incorporate higher cut-out intensity, and the tectosome with flexibility is a purpose, intensity level when artificial leather cuts off is higher, if when only the state of non-fiber fabric is compared, then because the effect of reinforcement material, the certain step-down of the morphotropism of artificial leather is even but so distortion is also quite high in the morphotropism of several 10% scope.That is when aforesaid technology, the damage that the reinforcement cloth and silk generates when tailor's cushion though can give inhibition, is reached though the high strength of the artificial leather after the complexing can give, aspect the apparent density of the non-fiber fabric after complexing, and improper.That is, usually so that the purpose that apparent density improves, even adopt the skill make non-woven thermal contraction after the complexing, technical elements at this communique, non-fiber fabric is because of having shrinkage hardly, so only can obtain to be equivalent to a little kenel change process that the torque of heavy twist long fiber silk of the formation silk of reinforcement cloth and silk is removed by heat treatment.In fact, apparent density for the laminated thing of each a slice of improving non-woven and cloth and silk, if one of heat treatment non-woven, cloth and silk, and make contraction, make on laminated artificial leather by heat treatment curling or wrinkling, concave-convex surface etc. takes place, step thereafter perplexs, and the goods grade is reduced.If when making the three-layered lamination kenel of non-woven/cloth and silk one fabric, though have contraction, its degree becomes very little again, and apparent density then almost improves.Again in above-mentioned communique, though record to make and adhere to PVA, but when giving PVA, fibre space portion is the filling of PVA institute, interfibrous spatial portion in this kind artificial leather becomes big, therefore the apparent density step-down of the artificial leather that makes when stretcher strain, also becomes the artificial leather structure of easy deformation.
Again, in Japanese kokai publication sho 55-57059 communique, announcement has by having the reinforcement cloth and silk that potential inotropic long fiber forms, this makes laminated being integral of the thing interlacing artificial leather of copying paper non-woven and this reinforcement cloth and silk that is formed by the staple fibre below the fibre length 10mm by High-Pressure Water after, the reinforcement cloth and silk is shunk, with the method for the apparent fibre density that improves artificial leather.Its main pluses and minuses are:
Because it is about becoming reinforcement cloth and silk that the potential shrinkage long fiber in mountain forms and copying the paper non-woven by what the staple fibre below the fibre length 10mm formed, through giving the cloth and silk that the current interlacing forms, cause is to copy the paper non-woven, it is less to constitute each interfibrous complexing, and and the reinforcement cloth and silk between complexing also low.Also only a little adheres to elastic resin, and when artificial leather was applied distortion, non-woven almost there is no deformation resistance and benefits, and the degree of the morphotropism of being reached itself promptly has the formation of having to lower.When observing the performance of goods again, because said method is, the shortcoming that also has fiber to come off easily than artificial leather.
Again, separately after the complexing end with non-fiber fabric, when lamination reinforcement is used the method for cloth and silk overleaf, during as if selection back side applying material, all can control the point of the deformation resistance of artificial leather whichsoever, again only with the state of non-woven, because of can carrying out shrink process, if when adopting the shrinkage non-woven, though can make apparent density the higher person, but between non-fiber fabric and reinforcement cloth and silk engage a little less than, add and can peel off man-hour, and need the step of usefulness for fitting, the shortcoming that therefore has manufacturing cost to improve exists.
For more effectively produce high deformation resistance (that is vertically and horizontal percentage elongation difference make laminated reinforcement cloth and silk when being the lower state of complexing degree in non-fiber fabric itself than engaging between person of low position's non-fiber fabric and reinforcement cloth and silk, make both mechanically very firm complexings promptly preferable by current or tailor's cushion.So by laminated complexing reinforcement cloth and silk, especially the reinforcement cloth and silk is fully selected on the mat mountain, the characteristic of the deformation resistance of end article artificial leather not only can be given and being invested, and in the fabrication steps of majority, the kenel of fiber artificial leather changes the elongation that its processing procedure pulling force of U causes) can give and suppressing.Especially when making the artificial leather that imitative seat answers, surface fiber density is the most important factor of decision goods grade again.
The emphasis that improves the apparent density of combined artificial leather and adopt is:
1,, needs to improve apparent density by the contraction of non-fiber fabric;
2, it is more important need making the elongation that does not cause because of the processing procedure pulling force.
Yet, to so far technology, still fail to make kenel and change (especially processing procedure pulling force cause elongation) and can give inhibition, and apparent density the higher person.
Summary of the invention
The purpose of this invention is to provide the manufacture method of a kind of superfine fiber non-woven through the artificial leather material of complex intensifying, add the reinforcement material by the superfine fiber non-woven, make its superfine fiber non-woven that becomes compound kenel, can be for use as light weight, high strength, high performance superfine fiber non-woven artificial leather material through complex intensifying.
