本考案は、スエード調又は銀面加工用人工皮革
に相当する、高級合成皮革用基材に関するもので
ある。[Detailed Description of the Invention] The present invention relates to a base material for high-grade synthetic leather, which corresponds to suede-like or grain-finished artificial leather.

去して後処理加工したものがある。 BACKGROUND ART Conventionally, synthetic leather substrates based on nonwoven fabrics have mainly been obtained by needle-punching synthetic fiber webs of 2 to 3 deniers such as nylon and polyester. This nonwoven fabric
Synthetic leather is formed by dry impregnating emulsion of synthetic resins such as SBR, acrylic, and vinyl chloride. In addition, the texture is similar to or better than natural leather,
A 2 to 3 denier sea-island composite fiber is spun by carding, and after needle punching and wet impregnation treatment, either the sea portion or the island portion of the composite fiber is dissolved and removed using a solvent. Some products have undergone post-processing.

ヤツプがあり、中間的な合成、人工皮革が見られ

公害規制上に非常な設備投資を必要とし、非常に
高価なものになつているのが現状である。 There is a considerable gap between these synthetic and artificial leathers, and at present there is no intermediate synthetic or artificial leather. The main reason for this is that with conventional synthetic leather, the limit for spinning synthetic fibers is 0.5 denier or more, so a fine denier base material cannot be obtained and it cannot be made into artificial leather. In addition, the base material for artificial leather, which uses sea-island type composite fiber,
In addition to the special spinning method, either the sea or the islands must be removed with a solvent, and the manufacturing process
The current situation is that it requires significant capital investment due to pollution regulations, making it extremely expensive.

を得ることが出来る。 The purpose of the present invention is to improve the above two drawbacks, form a synthetic leather base material under simple manufacturing conditions, and provide it with the characteristics of an artificial leather base material. That is,
Synthetic fiber web layer of 0.5-3.0 denier which can be carded and 0.5-denier obtained by melt-blowing method.
By combining fine denier nonwoven fabric sheets of denier or less and needle-punching only the fine denier nonwoven fabric sheet layer, the mechanical properties of the nonwoven web layer, such as tensile strength and tear strength required for the base material, are improved. The feel and texture of artificial leather is imparted by a fine denier nonwoven fabric sheet. By subjecting the base material of the present invention to conventional wet urethane resin processing, it is possible to obtain synthetic leather with an artificial leather-like appearance similar to artificial leather from which sea or island portions have been removed using sea-island composite fibers.
この様にして本考案品は、不織布シート層、フ
アインデニール不織布シート層の各々の性能を有
効に発現せしめたものである。 In this manner, the product of the present invention effectively exhibits the performance of each of the nonwoven fabric sheet layer and the fine denyl nonwoven fabric sheet layer.
しかし、人工皮革用基材として理想的な、メル
トブロー法により紡糸した0.5デニール以下のフ
アインデニール不織布シートは、製法上絡みが全
くなく引張、引裂強力が非常に弱い欠点がある。 However, fine denier nonwoven fabric sheets of 0.5 denier or less spun by melt blowing, which are ideal as base materials for artificial leather, have the disadvantage that they have no tangles due to the manufacturing process and have extremely low tensile and tear strength.
これを改良すべくニードルパンチ加工を行つて

がなく、層間剥離が発生し易く、ニードルパンチ
数を増加すれば織物の損傷が激しく強力保持性が
低下する欠点があつた。 Even if needle punching is performed to improve this problem, entanglement between fibers does not occur, and on the contrary, both tensile and tear strength decrease. Furthermore, a base material in which a woven fabric is inserted into the intermediate layer to provide strong retention has been considered, but since the fine denier nonwoven fabric sheet does not tangle, interlayer peeling is likely to occur, and increasing the number of needle punches may cause damage to the woven fabric. However, there was a drawback that the strength and retention properties were severely reduced.
本考案品は、上記の様なフアインデニール不織
布シート層の欠点をも改良した合成皮革用基材を
提供するものである。 The present invention provides a base material for synthetic leather that also improves the drawbacks of the fine denyl nonwoven fabric sheet layer as described above.
以下本考案の１実施例を図面に従つて説明す
る。 An embodiment of the present invention will be described below with reference to the drawings.
カード紡出可能ナ0.5〜3.0デニールの合成繊維

チ加工３を施した。 One side of a synthetic fiber web 1 of 0.5 to 3.0 denier that can be card-spun is 0.5 denier or less (preferably 0.03 denier) obtained by melt blowing.
Fine denier nonwoven fabric sheets 2 were laminated, and only the fine denier nonwoven fabric layer 2 was subjected to needle punching 3.
上記加工により、フアインデニール不織布層に

が得られた。 Through the above processing, there is no thick fiber of 0.5 denier or more in the fine denier nonwoven fabric layer, and on the outer surface of the synthetic fiber web 1 of 0.5 denier or more,
An ideal base material for artificial leather was obtained, exhibiting a suede-touch surface condition in which countless fine denier fibers 4 of 0.5 denier or less were randomly protruded.
ところで、合成繊維ウエブ１の両面にフアイン
デニール不織布シート２を積層して同様にして構
成することも可能である。 Incidentally, it is also possible to laminate the fine denier nonwoven fabric sheets 2 on both sides of the synthetic fiber web 1 and construct it in the same manner.

好ましくない。 In addition, as for the above needle punch processing conditions, the needle punch driving depth is preferably 10 to 12 mm, and 10 to 12 mm.
If it is less than mm, the nonwoven fabric web and the fine denier nonwoven fabric sheet layer cannot be entwined, causing delamination. If it exceeds 12 mm, the fine denyl nonwoven fabric sheet will be severely damaged, and the fine denyl nonwoven fabric sheet portion will be inserted into the thick nonwoven fabric web layer, causing a problem that thick fibers will appear on the surface, which is not preferable.
又ニードルパンチ数は、層間剥離と引張、引裂
強力に大きく影響し、500〜1000P／cm2が適当で

招くので好ましくない。 Further, the number of needle punches greatly affects delamination, tensile strength, and tear strength, and is suitably 500 to 1000 P/cm 2 . If it is less than 500P/cm2, there will be delamination and insufficient tensile strength, and if it exceeds 1000P/ cm2 , the tensile strength and tear strength will decrease due to surface damage to the fine denyl nonwoven sheet layer on the surface and cutting of entangled fibers. This is not desirable because it invites

At the expense of tensile strength and tear strength, the ratio of fine denier nonwoven fabric sheet is 50-70%, and the basis weight is 80-130.

The proportion of fine denier nonwoven sheet is 10~30%
It is preferable that the base material has a basis weight in the range of 200 to 300 g/m 2 .

Therefore, we have created an innovative suede-like synthetic leather that can be manufactured in the same process as conventional synthetic leather, even in areas where artificial leather with excellent texture and feel could not be used due to its high price. A base material for use is obtained.

ことができる等の効果を有する考案である。 In addition, fine denier nonwoven fabric sheets of 0.5 denier or less spun by the melt-blowing method have conventionally not been used as base materials for artificial leather because there is no intertwining between the fibers during manufacturing and the tensile and tearing strength is very weak. It can only be used as a base material for artificial leather by laminating a fiber web of 0.5 denier or more that can be carded and by adding restrictions to the needle punching conditions. Furthermore,
Needle punching from the fine denier nonwoven fabric sheet side ensures that there are no thick fibers of 0.5 denier or more on the fine denier nonwoven fabric layer side.
A large number of synthetic fibers on the surface of the web of 0.5 denier or more
Fine denier fibers of 0.5 denier or less exhibit a prominent surface condition, so secondary processing (wet impregnation) gives a backskin-like appearance, feels good on the skin, increases flexibility and strength, and improves the fine denier side. Since there are no thick denier fibers, it is possible to obtain synthetic leather with an extremely slimy texture. By increasing or decreasing the ratio of laminated fine denier nonwoven fabric sheets of 0.5 denier or less and synthetic fiber webs of 0.5 denier or more, it can be used for various purposes such as bags, bags, shoes, etc. in addition to clothing. It is an idea.
