A manufacturing method for a voluminous fabric with a smooth surface, a high compression resistance, a small residual deformation after repeated compression and with a minimum thickness of 2 mm consists in that a strip of planary fabric, produced by bonding of a fibrous web, composed of perpendicular or random oriented fibres in its whole thickness, is split by cutting, resulting in at least two layers of planary voluminous fabric products with a smooth surface, parallel to the plane of the planary fabric strip. A device for manufacturing voluminous fabrics with a smooth surface consists of a pair of conveyors (1 and 2) whose vertical and horizontal position to each other is controllable, and also of at least one endless steel blade strip (3) with a cutting edge, guided in between the outlet of the conveyors (1 and 2), a system of guide rollers (13) and supported by a guide slat (4), and further of at least two winding devices (6 and 8). The tangents to the roller of the winding devices (6 and 8) pass through the outlet of the feeding conveyors (1 and 2) at an angle of 15 to 45°. The steel blade strips with the cutting edges can be arranged in cascade perpendicular to the plane of the guide roller system (13), their distance from each other and from the feeding conveyors (1 and 2) being controllable.

Description

Manufacturing method for a voluminous fabric with a smooth surface and the related equipment
Technical Field
The invention is related to a method of producing voluminous fabrics with highly smooth surface and with fibres having random and/or perpendicular orientation to the fabric surface, and the equipment for production of such fabrics.
Description of the prior art
Highly voluminous fabrics serve above all as heat insulating and filler materials in the clothing industry of ready-made clothes and in the production of blankets, in the furniture industry for upholstering, as a heat and noise insulation in the building industry and in automotive industries. A considerable progress in the production of materials for said purposes has been achieved owing to production methods based on building-up highly voluminous layers consisting of a basic layer constituted by fibres of prevailing perpendiculat orientation. The most important of them are based on so-called perpendicular stratified web from the carding machine, reinforced by a proportion of thermoplastic matter which is present in the form of thermoplastic heat seal binding fibres in the blend. The machines under patent protection are based on two basic principles: A mechanical principle, when the fed web is taken-over by a vertically oscillating doffing comb and pushed between a conveyor of a hot air chamber, and a wire grid with a horizontally oscillating thrust batten (CS AO 235494). A rotational principle is applied in the design concept according to CS P 280153. It uses a principle based on fibrous web feeding between a pan and a set of discs, and pushing between the dents of a working cylinder. The web loops so formed are taken over by a wire grid and put onto a conveyor of a hot-air chamber, the layer built up in this way is mechanically or heat reinforced, e.g. according to EP 0648877. This type of highly voluminous fabric material found a wide application not only owing to its high heat insulating quality, but above all for its excellent shape memory, i.e. its compression resistance and its shape-recovering ability after a repeated compression, which may be encountered during its use. This type of voluminous fabric materials finds a wide application in a thickness range from 20 up to 120 mm.
A wide applicability potential can be seen for products of a similar structure, but with a thickness as small as 2 mm. The existing design art and available machinery do not allow it.
Nature of the invention
The limitations mentioned above are removed by a manufacturing method for a voluminous fabric with a smooth surface, high compression resistance, small residual deformation after a repeated compression, with a thickness of 2 mm according to the invention, consisting in that a strip of flat fabric, formed by bonding a fibrous web with perpendicular and/or random oriented fibres in its whole thickness is divided by a longitudinal splitting cut, giving origin to at least two layers of planary voluminous fabric materials with a smooth surface, which is parallel to the plane of a planary fabric strip. The splitting cut may be made on a strip of planary fabric built-up of a perpendicular deposited fibre web, which is heat-bonded owing to the content of a proportion of thermoplastic heat-seal binding fibres, or a strip of a planary fabric built up of perpendicular deposited fibrous web, which is surface-bonded by a set of rotating elements, twisting the ends of protruding fibres into the form of yarn, or a planary fabric strip, built up of a pneumatically confected fibrous web bonded by a water dispersion of a polymerous compound, or of a heat- sealed fibrous web with addition of thermoplastic binding compounds.
The equipment for the production of voluminous fabric products with a smooth surface consists of a pair of conveyor belts, the vertical and horizontal position of which to each other is controllable, and also of at least one endless steel blade strip with a cutting edge, guided between the outlet extremities of said conveyor belts by a system of guiding rollers and supported by a carrying slat, and also of at least two winding devices.
The tangents to the winding device roller system running through the outlet extremity of the feeding conveyors form preferably an angle of 15 to 45° with the vertical axis of the feeding rollers.
The steel blade strips with cutting edges may be arranged in cascade perpendicular to the plane of the guide roller system, their distance from each other and the distance from the feeding conveyors being controllable.
By split-cutting of the planary fabric having a larger thickness at least two voluminous fabric layers are produced, each of them having a highly smooth surface, as necessary for lamination with upholstery fabric materials required above all by the automotive industry for lining of the car body interior surfaces and for upholstering of the seats. The device enables to produce products with various thickness owing to a simple control of the distances between the steel blade strips with the cutting edge and the conveyors from each other.
Survey of Figures
The invention is nearer explained on the enclosed figures. Fig. 1 shows a strip of planary fabric material. Figs 2a, 2b show side views of the device for split cutting of the planary fabric strip.
Examples of Embodiment
Example 1
The device for split cutting of the semi-finished product of planary fabric strip is shown on two side views in Figs 2a, 2b. The device for split cutting of voluminous textiles with a smooth surface consists of a pair of conveyors 1 and 2, whose vertical and horizontal position to each other is controllable, further of two endless steel blade strips 3 and _3_. with cutting edges, which is guided between the outlet of the conveyor pair and 2 by guide slats 4 and on a system of guide rollers 13 and 3_ , and of winding devices 6, 7 and 8.
The speed of the feeding conveyors 1_and 2_ is separately controllable in the speed range from 1 to 2 m per minute.
The steel blade strips 3 and 3 are arranged in cascade perpendicular to the plane of the set of guide rollers .13 and 13', while their distance from each other and from the feeding conveyors 1 and 2 is controllable.
The level position of the steel strips 3 and 2T with the cutting edges is resettable in the range up to +/- 20 mm.
The split layers V\_ and Vλ of the voluminous fabric with smooth surface wound on the winding device rollers 6 and 8 , or the tangents to the winding device rollers 6 and 8 passing through the outlet of the feeding conveyors I and 2 constitute with the vertical axis of the feeding rollers 1 and 2 an angle of 15 to 45°.
Example 2
A strip of a planary fabric 9 shown in Fig. 1 , manufactured of 80 % of polyester fibres and 20 % of bonding copolyester fibres using a process based on a perpendicular stratifica- tion of a fibrous web from a carding machine with hot-air heat-seal bonding, at a thickness T = 24 mm and density 50 kg per cu.m is guided between the conveyors 1 and 2 and pushed against steel blade strips 3 and 4 with cutting edges, and is split in three layers 10, H and Vλ, which are subsequently wound up on the winding device 6, 7 and 8. The layers 10, H and 12 of voluminous fabric with highly smooth surface on the split area, with a thickness ti, t 2, t 3 = 8 mm obtained in this way serve for lamination with upholstering fabric, and have been used as upholstering material for car seats. They replace a foamed polyurethane layer, unlike which the voluminous fabric with a smooth surface is environmentally and hygienically more favourable and moreover more stable in use. Compressed 300 000 times to 20 % of its original thickness, the original free thickness was reduced merely by 3 %.
Industrial applicability
Voluminous fibrous fabric at a minimum thickness of 2 mm with a highly smooth surface according to the invention finds application in the textiles industry, upholstery, above all for lamination with upholstering fabrics as required above all by the automotive industry for lining of cab interior and for seats upholstering.
