Description
10~2869 This invention relates to a method for manufacturing an air-permeable lining material, according to which there is applied on a temporary carrier at least one layer of plasti-sol, gel or solution of a film-forming thermopla~tic ~ynthetic material, said layer of synthetic material being ~tripped off, after hardening, from the temporary carrier, and related also to a lining material manufactured according to said method.
Lining material of this kind is particularly suitable for being used in upholstering seats, arms and rests of seats of vehicles and vessels, furniture or panels, f~r the manufac- -ture of cushions and mattresses and for other purposes for which an air-permeable lining of synthetic material, the so-called breathing synthetic leather, is desired.
It is to be noted that the term lining material means both one single layer of synthetic leather consisting of a plastic deformable material, such as polyvinyl chlorlde or polyurethane, said layer being applied on its surface with a certain pattern, and a synthetic leather con~isting of se-veral layers, one of said layers being a textile layer sup-ported by a layer of synthetic material. Such a synthetic leather in most embodiments is generally known.
All of the kinds of synthetic leather so far known present the drawback that it is not possible to manufacture seamless articles provided with such a synthetic leather in moulds by the use of a vacuum to form the synthetic leather into the mould followed by the incorporation of the foam, since ir 1~8~869 said known types of synthetic leather the pores provided therein prevent the drawing of a vacuum under the layer of synthetic material.
Moreover, during the foaming up there would be the risk of the foam penetrating outwards through the pores.
This drawback is eliminated by the air-permeable lining material manufactured according to the method of the invention in that one uses a temporary carrier comprising thin project-ions extending obliquely relative to its upper surface, said projections penetrating through the layer of synthetic mate-rial formed on the carrier and extending at least up to the upper surface of said layer of synthetic material so that consequently after the layer of synthetic material is stripped from the carrier narrow oblique passages are formed in said layer of synthetic material. Since the thermoplastic syn-thetic material permits an eLastic deformation when pressure is exerted thereon, the oblique passages formed by the thin oblique projections, which in the inoperative condition of the covering material are open, will be shut as a result of the pressure exerted on the covering material during vacuum drawing in a cavity mould, so that no air can flow anymore through said passages. When after the manufacture of the article of synthetic material this pressure is relieved by allowing air to enter under the lining material in the mould, the passages open again thus ensuring a good ventilation. As during the foaming up the passages are closed, the advantage is obtained that no foam can emerge from these passages.
Another advantage of the method according to the in-~08~869 vention consists in that, after the layer of synthetic leatherhas been stripped off from the carrier, said layer does not re-quire any further processing to make it air-permeable. This entails the advantage that the device for performing the me-thod according to the invention is very simple, comprises few parts thus requiring little space and may be constructed at little cost. Said device comprises a tapelike carrier sup-ported by rollers, at least one of said rollers being driven, a feeding device for the synthetic material and a heating or drying device for the synthetic material applied on said carrier and is characterized in that the tape-like carrier is provided with a plurality of thin projections extending ob-liquely relative to the surface. Said projections preferably may consist of thin needles.
The oblique projections or needles may extend according to an angle of 15-25 relative to the surface of the carrier.
As a result of this oblique position the passages formed in the synthetic leather are of a much greater length than pas-sages extending perpendicularly to the surface of the synthetic leather. The ratio between the diameter and the length of the operative part of the projections or needles may preferably range between l:10 and 1:50. Thus a reliable closing of those passages is arrived at when a vacuum is drawn in a mould under the layer of synthetic leather. The operative part of the pro-jections or needles means that portion of the projections or needles which during the manufacture of the air-permeable covering material is located in the layer of synthetic material.

According to a broad aspect of the present inven-tion, there is provided a method for manufacturing an air-permeable lining material, The method comprises applying on a temporary carrier at least one layer of plastisol, gel or solution of a film-forming thermoplastic synthetic material.
The layer of synthetic material is stripped off, after harden-ing, from the temporary carrier. The method is characterized in that the temporary carrier comprises a plurality of thin projections extending at an oblique angle relative to the surface of the carrier, the projections penetrating through the layer of synthetic material formed on the carrier and extending at least up to the upper surface of the layer of synthetic material such that after the layer of synthetic material has been stripped from the carrier, oblique passages are formed in the lay0r of synthetic material, According to a further broad aspect of the present invention, there is provided an air-permeable lining material which comprises a hardened layer of plastisol, gel or solution of a film-forming thermoplastic synthetic material. The layer has a plurality of passages therethrough disposed at an ob-lique angle relative to opposed surfaces of the layer.
Accordîng to a further broad aspect, the passages in the layer are disposed at an oblique angle lying in the range of from 15 to 25 to the surfaces of the layer.
- 4a -1~8~869 The invention will be further explained below with ref-erence to the drawings showing diagrammatically and by way of examE~le a device for performing the method according to the in-vention, and part of the lining material manufactured according to scLid method and a cushion uphol~tered with said lining material.
The drawings show in Fig. 1 diagrammatically a side view of the device, Fig. 2 a section of part of the covering material on a considerably enlarged scale, Fig. 3 in perspective a cushion upholstered with the lining material according to the invention.
The device diagrammatically shown in Fig. 1 comprises two rollers 1, 2 across which an endless tapelike carrier 3 is laid.
One of said rollers is driven by a driving device. This carrier may consist of any suitable material from which the lining material 4 can be easily stripped off. If desired the device may be provided with a feeding means (not shown) for applying on the carrier a product that furthers the stripping of the lining material 4 from the carrier 3. This carrier 3 should be resistant to solvents used for forming the lining material thereon and may present a grain pattern.
As a synthetic material one uses a plastic synthetic sub-stance, for example polyvinyl chloride or polyure~hane, which -in the form of a plastisol or a sultion is applied by a feeding device 5 in a layer of uniform thickness on the carrier 3.
The carrier 3 thus provided with a layer passes during its movement through a heating tunnel 6 in which the layer of syn-thetic material 4 is hardened, whereupon the lining material 4 thus manufactured is wound on a roller 7.
.
~ ~0821369 As is apparent from Fig. 1 the carrier 3 is provided with a great many thin oblique projections or needles 8. Said pro-jection~ or needles 8 extend according to an angle of 15-25 relative to the surface of the carrier 3. Said projections or needles 8 form narrow passages 9 in the lining material, which corre~ponding to the oblique position of the projections or needles 8 extend according to an angle of 15-25 relative to the surface of the lining material 4. The ratio between the diameter and the length of said pas~ages i~ preferably between 1 : 50 and 1 : 10. At a thickness of the layer of synthetic material of 0.1 - 0.5 mm passages with a diameter of about 0.03 mm are preferred. The projections or needles 8 may be arranged in row~, for example, at a distance of 3 mm from one another, the distance between each two consecutive projections or needles of said rows amounting for example to 2 mm. The diameter of the projections or needles 8 corresponds to the diameter of the air passages 9 and is therefore 0.03 mm. The thickness of the manufactured lining material is usually 0.1 - 0.5 mm. Fig. 3 shows a cushion the lining material of which comprise~ passages 9 arranged in rows 11, said lining material having been manu-factured with the above-described device.
If a lining material has to be manufactured with a textile layer the aforedescribed device may be embodied as described in U.S. Patent No. 3,650,880 i~ued March 21, 1972. Since the carrier 3 is provided with thin projections or needles 8 that penetrate through th~ layer of synthetic material 4 applied on the carrier, this presents the advantage that the passages 9 formed by said projection~ or needles in the layer of synthe-tic material cannot be closed by the adhesive layer applied on said layer o~ synthetic material for adhering the textile layer to the synthetic material layer 4, because the needles 8 are still in these passages. If desired the textile layer may also be applied on the layer of synthetic material 4 when the latter is still sticky.
Instead of an endless carrier 3 one may also use a carrier with ends which is unwound from a feeding roller onto a winding roller. The projections or needles 8 need not have a round cross-section but they may also have an oval of any other suitable cross-section.
