Abstract

Velour fabrics such as velvet are known and it is known to provide such fabrics in the form of a web having a plastics film on the surface remote from the pile. Direct application of the film gives rise to disadvantages because of the unevenness of the reverse side of the fabric and attempts to overcome these disadvantages have been unsatisfactory. The invention overcomes these disadvantages by first applying to the reverse side of the fabric a liquid foamed curable plastics material and curing this under tension to provide a flat surfaced open cell plastics layer 3 which acts as an advantageous substrate surface for the plastics film 4. <IMAGE>

Description

SPECIFICATION Improvements in and relating to velour fabrics and their manufacture The invention relates to velour fabrics and their manufacture.
It is known to apply a film coating to the back of webs of velour textile material. The coating may in particular have a leather-like surface intended to form the exterior of the finished article. However, the back of the velour textile web cannot satisfactorily be coated directly because it is not sufficiently flat.
Abrasion or polishing of the back of the web has been effected but has been found not to make the back of the web sufficiently flat, regardless of the means by which the web has been manufactured, to facilitate direct application of the film.
Therefore, in the past, coating has been carried out by using an intermediate carrier made from paper and having a plastics paste, the carrier being brought into contact with the velour fabric in order to transfer the plastics paste to the reverse side of the velour fabric. However, in practice, this method is complicated, subject to faults and expensive.
According to the invention, there is provided a method of manufacturing a velour fabric web, which method comprises forming a web of velour fabric, coating the web on a surface remote from the surface having a pile with a coating of a liquid curable foamed plastics material, curing the coating to provide a layer of an open cell foamed plastics material, the curing being effected with the web under tension, and applying over the layer of plastics material a film comprising a plastics material.
The velour fabric web may be formed, for example, by weaving, knitting or tufting. The velourfabric may conveniently be velvet or corduroy although the term "velour fabric" is not herein restricted to these materiais but may be any material having a pile.
In a second aspect, the invention provides a velour fabric web comprising a velour fabric substrate bearing, on its surface remote from the surface thereof, having a pile, a layer of an open-cell foamed plastics material which layer compensates for unevenness of the substrate surface, said layer having adhered thereto in overlying relationship a film comprising a plastics material.
The liquid curable foamed plastics material will in practice normally be a foamed liquid dispersion of a plastics material in a solvent, usually an organic solvent, which evaporates in the curing step.
The plastics material may conveniently be a soft polyurethane resin or alternatively may, for example, be a poly (meth) acrylic acid ester which is cross-linkable. Such plastics materials may, for example, be used in the form of a dispersion thereof in water, the dispersion conveniently containing from 40 to 60 g. resin per 1009 of dispersion.
The foamed character of the liquid curable foamed plastics material will normally be provided by mechanical aeration of the liquid material. For example, the liquid may be aerated by The liquid foamed plastics material preferably has a weight of between 300 and 800 g/litre.
The liquid foamd plastics material may, for exam ple, be applied by wiping or by rolling or alternative ly coating may be accomplished by brushing.
Curing of the applied liquid foamed plastics mate rial will normally be effected thermally, conveniently by applying heat whilst the tension referred to is maintained by retention of the velour fabric web under tension in a tensioning frame. A curing temperature in the range from 1 60"C to 1 80"C is convenient.
The open cell foamed plastics layer preferably has a weight of from 50 to 100 g/m2.
The liquid foamed plastics material penetrates into all the uneven areas of the back of the velour fabric web and fills them to provide an outer surface which is sufficiently flat to apply a plastics film. The cured foamed plastics material has flexibility and open pore structure giving the web as a result an ability to hang in the same way as the velour fabric web itself and this will be appreciated to provide significant advantages when the web is used in the manufacture of clothing and the like.
After curing of the liquid foamed plastics material, the coated velour fabric web is provided on the surface of the foamed plastics remote from the web with a film comprising a plastics material. The film will normally be provided by calendering.
Calendering may conveniently be effected using a pair of calender rolls of which the upper roll is a steel smooth surfaced roll having an elevated surface temperature of, for example, approximtely 1 80 C.
Conveniently, the calendering may be conducted at a pressure of from 6 ta 12 tonnes. The web may be calendered at a speed of passage through the rolls of about 10 m/minute Calendering may advantageously be effected using a film-carrying intermediate carrier made, for example, of paper, heat and pressure applied to the film/carrier in calendering causing transfer of the film securely to the velour fabric web.
Plastics films on a paper carrier are commercially/ available. Commercially/available products of this type are known for use, for example, for applying a design to foils unsuitable for treatment by conventional sublimation transfer processes.
The plastis film may conveniently be made of such a polymer as a poly (meth) acrylic acid ester. The film may contain one or more colorants, for example in the form of a design incorporated into the body of the film. Alternatively, the film may have surface colouration, for example, a design carried on the film surface. Pigments will normally be preferred for colouration purposes.
A surface design may most conveniently be provided on the film surface during calender transfer of the film to the velour fabric. In so doing, a design carrier will normally be fed to the nip of the calender rollers so that the design-carrying surface is brought into contact with the film as the latter is brought into contact with the velour fabric.
The film may alternatively or additionally be; provided with water repellency. This may be achieved by treating the film, after the film has been applied, with a hydrophobic agent applied to the film as, for example, a solution of such an agent in a solvent. Despite the large quantities of hydrophilic substances normally present in the foamed plastics layer, a water-repellent surface may be achieved in this way; if the hydrophobic agent were to be applied to the foamed plastics surface, the desired effect would not be achieved or would be achieved only to a very small extent and additionally this would have a deleterious effect in making difficult the application of the plastics film.
A velour fabric web according to the invention is illustrated diagrammatically in the accompanying drawing.
The web shown in the drawing comprises a velour fabric layer 1 having a riased fibrous nap 2.
A thin flexible layer 3 comprising open-pored mechanically aerated plastics material is applied to the back of the material 1, the layer 3 compensating for unevenness of the back of the article. The layer 3 has a perfect flexibility even at-25'Cand perfect resistance to chemical detergents to which the article may be subject during cleaning.
A thin plastics foil 4 is applied to the exterior of the layer 3 and is secured firmly to the layer 3 as a result of heat and pressure applied during a calendering operation.
The following is a specific Example intended to illustrate the invention: EXAMPLE A piece of velour fabric is produced, by knitting a fabric on a Wildtmann Machine, having a knitted cotton substrate and a pile of acrylic fibres. A dispersion of a foamable polyurethane resin in water containing 40 to 60 weight per cent resin and foaming agent is produced and mechanically foamed by agitating it by means of fast running stirrers so that the thus obtained foamed material contains about 20 per cent solid material. Said material is applied to the back side of the knitted pile fabric by means of a Doctor Blade, and the foamed plastics layer has after drying, a weight of approximately 50 to 100 g/m25.
The resulting backed web of velour fabric was then calendered to provide a thin polyacrylic acid ester film. The calendered product was found to posses flexibility comparable to the untreated web of velour fabric and in particularwas found to havecompara- ble hang properties.
