Abstract

A method of adhering an adhesive to a fabric piece comprising the steps of providing a fabric piece, pre-treating a portion of the fabric piece to increase its surface wettability; and, pressing the adhesive and the pre-treated portion of the fabric piece together

Description

A method of adhering an adhesive to a fabric piece The present invention relates to a method of adhering an adhesive to a fabric piece. The present invention also relates a composite structure. The present invention also relates to an apparatus for adhering an adhesive to a fabric. More particularly, but not exclusively, the present invention relates to a method of adhering an adhesive to a fabric piece whereby a portion of the fabric piece is pre-treated to increase its wettability before the adhesive and pre-treated portion of the fabric piece are pressed together, preferably along with the application of heat. More particularly, but not exclusively, the present invention relates to a composite structure produced by such a method and also an apparatus for performing such a method.

Methods of adhering an adhesive to a fabric piece are known. Such methods typically comprise heating the adhesive and pressing it into contact with the fabric piece to form a bond. The problem with certain such methods can be the limited time available to form a bond between the adhesive and the fabric piece.

With flat fabric pieces this problem can be partially overcome by adhering the adhesive in a two step process. Firstly the adhesive is warmed to make it tacky then positioned on the fabric piece where it forms a weak bond. The fabric piece/adhesive composite is then placed in a flat bed press where it is further heated and pressed until an effective bond forms. This process is however slow.

Curved fabric pieces, for example knicker legs or bra cups, can be more difficult. With curved fabric pieces the fabric piece and adhesive film are passed typically though a pair of narrow heated plates which heat the fabric piece and film to the desired temperature.
The curved fabric piece can however only be passed slowly through the plates due to the time it takes for a bond to form.

CONFIRMATION COPY

The method according to the invention seeks to overcome the problems associated with the prior art.

Accordingly, the present invention provides a method of adhering an adhesive to a fabric piece comprising the steps of providing a fabric piece;

pre-treating a portion of the fabric piece to increase its surface wettability; and, pressing the adhesive and the pre-treated portion of the fabric piece together.

The method according to the invention enables a bond to be formed between the fabric piece and adhesive more rapidly than known methods. This improves the throughput of machines for adhering adhesive to fabric pieces, so reducing manufacturing cost. It also enables fabrics to be used which hitherto were incapable of being effectively bonded.

At least one of the pre-treated portion of the fabric piece and adhesive can be heated whilst the pre-treated portion of the fabric piece and adhesive are pressed together.

At least one of the pre-treated portion of the fabric piece and adhesive can be pre-heated prior to being pressed into contact with the other.

The step of pre-treating the portion of the fabric piece can comprise roughening the surface of the portion of the fabric piece.

The step of pre-treating the portion of the fabric piece can comprise exposing the surface of the portion of the fabric piece to a plasma.

The plasma can be a neutral plasma.
The step of pre-treating the portion of the fabric piece can comprise etching the surface of the portion of the fabric piece with an etchant.

The step of pre-treating the portion of the fabric piece can comprise coating the surface of the portion of the fabric piece with a hydrophilic coating.

The step of pre-treating the portion of the fabric piece can comprise coating the surface of the portion of the fabric piece with a primer.

The method can further comprise the step of adhering the side of the adhesive remote from the pre-treated portion of the fabric piece to a portion of a second fabric piece.

The portion of the second fabric piece can be preconditioned to increase its surface wettability.

The pre-treated portion of the fabric piece and the pre-treated portion of the second fabric piece can be spaced apart portions of the same fabric piece.

The adhesive can be a film.

The adhesive can be a thermoplastic, preferably polyurethane.
The adhesive can be a coating on a_tape.

Preferably, both sides of the tape are coated with an adhesive.

In a further aspect of the invention there is provided a composite structure comprising a fabric piece, a portion of the. surface of the fabric piece having a greater surface wettability than the surrounding surface; and, an adhesive bonded to the portion.

Preferably, the composite structure further comprises a tape bonded to the opposite side of the adhesive to the portion of the fabric piece.

In a further aspect of the invention there is provided an apparatus for adhering an adhesive to a fabric piece comprising first and second plates having a gap therebetween;

a displacement means for drawing a fabric piece and an adhesive between the plates where they are pressed together;

a pre-treating means for pre-treating a portion of the surface of the fabric piece to increase its surface wettability before being received by the plates.

The pre-treating means can be adapted to roughen a portion of the surface of the fabric.
The pre-treating means can be adapted to expose a portion of the surface of the fabric.
piece to a plasma, preferably a neutral plasma.

The pre-treating means can be adapted to etch a portion of the surface of the fabric piece with an etchant.

The pre-treating means can be adapted to coat a portion of the surface of the fabric piece with a hydrophilic coating.

Preferably, the apparatus comprises a heater for heating at least one of the adhesive and fabric piece prior to being received by the plates.

Preferably, at least one of the plates is heated.
The present invention will now be described by way of example only and not in any limitative sense with reference to the accompanying drawings in which figure 1 shows an apparatus for adhering an adhesive to a fabric piece by a method according to the invention in schematic cross section; and, figures 2(a) to 2(d) show composite structures produced by methods according to the invention.

Shown in figure 1 is an apparatus 1 for performing a method according to the invention in schematic cross section. The apparatus 1 comprises first and second plates 2, 3 having a narrow gap 4 therebetween.

A displacement means (not shown) draws a film of adhesive 5 through the gap 4 as shown. The adhesive 5 is typically a thermoplastic adhesive 5, preferably polyurethane.
As the film of adhesive 5 is drawn towards the gap 4 it is preheated by a preheating apparatus 6. The pre-heating apparatus 6 may comprise a hot plate over which the film 5 is drawn. In alternative embodiments the pre-heating apparatus 6 provides one or more jets of hot air which heat the film of adhesive 5. The heating of the film of adhesive 5 is sufficient to make it tacky.

A fabric piece 7 is also drawn into the gap 4 by a displacement means (not shown).
Before the fabric piece 7 reaches the gap 4 it passes proximate to pre-treating means 8 which pre-treat a portion of the fabric piece 7, increasing its surface wettability.

In the current embodiment the pre-treating means 8 pre-treats a portion of the fabric piece 7 by exposing its surface to a neutral plasma. This causes chemical changes in the surface, increasing its wettability.

When the pre-treated portion of the fabric piece 7 and the heated film of adhesive 5 reach the gap 4 they are pressed into contact by the plates 2,3, bonding the adhesive 5 to the pre-treated portion of the fabric piece 7. The increased surface wettability of the pre-treated portion of the fabric piece 7 enables a bond to be formed between the adhesive 5 and pre-treated portion more rapidly than with known methods so increasing the throughput of the apparatus 1 and reducing manufacturing costs.

In alternative embodiments of the invention (not shown) alternative pre-treatment means 8 are provided. In one embodiment the pre-treatment means 8 etches the surface of a portion of the fabric piece 7 with and etchant. In an alternative embodiment of the invention the pre-treatment means 8 coats the surface of the portion of the fabric piece 7 with a hydrophilic coating. In a further alternative embodiment of the invention the pre-treatment means 8 roughens the surface of the portion of the fabric piece 7.
In a further alternative embodiment of the invention the pre-treatment means 8 singes the surface of the portion of the fabric piece 7. In a further alternative embodiment of the invention the pre-treatment means 8 exposes the surface of the portion of the fabric piece 7 to ozone, typically generated by an electric spark.

In the above embodiments the adhesive 5 is provided as a film to the pre-treated portion of the fabric piece 7. In an alternative embodiment the adhesive 5 is a coating on a tape 9.
The adhesive 5 bonds the pre-treated portion of the fabric piece 7 and tape 9 together, strengthening the fabric piece 7.

In an alternative embodiment of the invention the method is performed twice.
In a first step the adhesive 5 is first bonded to a first pre-treated portion of a fabric piece 7 by passing it through the apparatus 1. The composite fabric and adhesive is then passed through the apparatus I again with a second fabric piece 10, a portion of which has been pre-treated. The fabric pieces 7,10 are arranged such that the layer of adhesive 5 is sandwiched between the pre-treated portions of the fabric pieces 7,10 . As the fabric pieces 7,10 pass through the apparatus 1 the adhesive 5 bonds the pre-treated portions of the two fabric pieces 7,10 together. The resulting structure is shown in figure 2(a). A

similar method is also possible using a layer of adhesive 5 on both sides of a tape 9. In a first pass through the apparatus 1 one side of the tape 9 is bonded to a pre-treated portion of a first fabric piece 7. In the second pass through the apparatus 1 the opposite side of the tape 9 is bonded to pre-treated portion of a second fabric piece 10. The resulting structure is shown in figure 2(b). The first and second pre-treated portions may be separate portions of the same fabric piece 7. The resulting structures are shown in figures 2(c) and 2(d).

In an alternative embodiment of the invention both bonding steps are performed simultaneously. If the first and second pre-treated portions are portions of the same fabric piece 7 this can be achieved by passing the fabric piece 7 through a fabric folder (not shown) to sandwich the layer of adhesive 5 (or tape 9 having an adhesive 5 on both sides) therebetween before passing the composite structure through the plates 2,3.

In an alternative embodiment of the invention the first and second bonding steps are performed by passing the fabric piece 7 and adhesive 5 through a first apparatus I to bond the adhesive 5 and first pre-treated portion of the fabric piece 7 together. The resulting composite structure is then passed along with a second fabric piece 10 through a second apparatus I where the adhesive 5 is bonded to a second pre-treated portion of the second fabric piece 10.

In all of the above embodiments the adhesive 5 is heated before being passed through the plates 2,3. In alternative embodiments the plates 2,3 are heated so that they simultaneously apply both heat and pressure to the pre-treated portion of the fabric piece 7 and adhesive 5 passing between them.

In an alternative method according to the invention the portion of the fabric piece 7 is pre-treated and then bonded to the adhesive 5 in a flat bed press.

In an alternative method according to the invention ink is printed in a pattern on a sheet, typically a paper sheet. An adhesive 5, typically a powder adhesive 5, is adhered to the ink. The adhesive 5 is then pressed into contact with the pre-treated portion of the fabric 7 forming a bond. Finally, the paper is removed revealing the ink pattern on the fabric 7.
In an alternative embodiment of the invention the adhesive 5 is polyester.
