Definitions

• the invention relates to laminated articles and in particular to an applique for applying to fabric garments and other textile substrates.
• An applique comprising an adhesive polyvinylchloride material laminated onto a paper backing sheet which is then fully flocked in a single colour flock material is known.
• the flock fibres may be screen printed, in the case of a multicoloured article, with desired colours to form a required badge or motif.
• the sheet and flock is then cut up into individual badges or motifs for application by high frequency welding to a textile substrate.
• the main difficulty is the processing difficulty involved in screen printing a desired image onto the flock material.
• Different coloured inks are required which must be applied in a number of different stages and the badge thus formed must be cured at high temperature.
• the flock fibres are of rayon viscose 1.7 DTEX 0.5mm flock which is adapted to receive the necessary screen printing ink.
• the abrasion resistance of the badge thus formed is often not satisfactory.
• the colours in the badge are often not sufficiently stable in repeated machine washing of the garment to which the badge is applied.
• the fibres have a relatively rough feel and consequently often detract from the feel of the garment to which they are applied.
• the applied print has a stiff mounting handle on the fabric which also detracts from the product.
• an applique comprising:-
• the fibres are flocked onto the adhesive through a screen having openings for the flock fibres corresponding to at least portion of the desired motif.
• the flock fibres are of synthetic fibre, preferably polyamide fibre, most preferably of polyamide fibres 3.3 DTEX 1mm. These fibres give a partially plush finish.
• at least two and possibly several different coloured flock fibres are flocked onto the adhesive.
• flock fibres of different colours are applied in sequential flocking steps.
• the fibres are flocked onto the adhesive in a desired motif or pattern through separate screens.
• the applique includes a support layer on which the base layer is supported. This assists in achieving dimensional stability.
• the base layer is peelably attached to the support layer.
• the support layer is of stiff paper material or similarly adapted substrate.
• the adhesive is applied to the base layer only in the region to which the flock fibres are to be flocked.
• the adhesive is applied to the base layer through a screen.
• the flock receiving adhesive is selected.to be compatible with both the flock fibres and the base material. Typically the adhesive is compatible with the polyamide fibres and polyvinylchloride film material.
• the base layer is of polyvinylchloride film material which is suitable for fixing to a fabric by high frequency welding.
• the invention also provides a method of forming an applique carrying a motif or badge to be applied to a fabric comprising the steps of:-
• the method includes flocking flock fibres of at least several colour flock fibres onto the adhesive in a desired sequence to form a desired coloured motif.
• the adhesive is applied to the base layer only in the region to which the fibres are to be flocked.
• the adhesive is applied to the base layer through a screen.
• the flock fibres are applied to the adhesive through a screen.
• a screen typically there are at least two different coloured flock fibres which are applied to the adhesive in sequential flocking steps.
• Most preferably the coloured flock fibres are flocked onto the adhesive through separate screens.
• the method includes the step- prior to applying > the adhesive, of providing a support layer for the thermoplastic base layer.
• the adhesive is cured after application of the flock fibres.
• the invention further provides a method of applying an applique according to the invention to a fabric support comprising the step of:-
• the method further includes the step, prior to welding, of interposing a layer of foam or the like material between the base layer of the applique and the fabric support.
• Fig. 1 is a diagrammatic cross sectional view of an applique according to the invention
• Fig. 2 is a diagrammatic cross sectional view illustrating the application of the article of Fig. 1; and Figs. 3a to 3f are schematic drawings of various steps used in the method of the invention.
• a high frequency weldable plastics such as polyvinylchloride sheet or film having a thickness of between 0.15mm and 0.30 mm forming a base layer is applied onto a support layer, preferably by a flow process in which the PVC in a liquid form is applied to the support layer.
• the support layer in the preferred arrangement is of a stiff paper material which allows the plastics film to be easily peeled off the support layer after processing.
• the application of the PVC onto a support layer facilitates the subsequent processing of the product whilst maintaining the dimensional stability of the PVC when subjected to heating.
• a layer of permanent adhesive is applied to the upper side of the base layer of polyvinylchloride film material.
• the adhesive is applied through a screen only to the area of the base layer on which a desired motif or badge is required.
• the adhesive is compatible with both polyamide fibres and PVC.
• Polyamide fibres of 3.3. DTEX 1mm are flocked onto the adhesive using conventional flocking techniques.
• the fibres are flocked onto the adhesive to produce a desired motif or badge on the polyvinylchloride base film.
• a desired motif or badge the fibres are flocked onto the adhesive in a desired sequence using separate screens for each colour.
• the applique thus formed is then treated, typically at 160°C for approximately three minutes to cure the adhesive and to ensure permanent adhesion of the flock fibres to the base polyvinylchloride adhesive.
• the sheet of flocked film material thus formed has a plurality of applique badges or motifs spaced-apart therealong. This sheet is- then cut up into individual appliques which may be applied to textiles or other substrates, after removal of the backing paper using conventional high frequency welding techniques. If an additional three dimensional effect is required a layer of polyurethane foam may be interposed between the PVC film and the fabric to which the applique is to be attached.
• Fig. 1 there is illustrated an applique according to the invention and indicated generally by the reference numeral 1.
• the applique 1 comprises a support layer 2 of paper material coated with a release agent.
• a PVC base layer 3 which is typically 0.15 to 0.3 mm thick is applied, for example in a liquid form, onto the paper support sheet 2.
• An adhesive 4 which is compatible with the PVC sheet and with polyamide flock fibres 5 is then applied onto the PVC sheet 3 through a screen 20.
• the adhesive is a plastisol polyvinyl chloride based adhesive, made up of a PVC resin, with an appropriate plasticizer blend, and corresponding curing agents and stabilizer.
• the polyamide flock fibres 5 are typically 1 mm 3.3 DTEX and are electrostatically flocked in one or more colours, in sequence, onto the pattern of the adhesive 4.
• the fibres are flocked onto the adhesive using a screen to achieve a desired motif or badge.
• the fibres are applied sequentially through different screens for each colour fibre.
• each sheet After flocking in sheet form and heat curing, each sheet is cut up into individual appliques.
• the paper base layer 2 is peeled off and the PVC sheet 3 is placed directly onto a textile fabric 10.
• the PVC is welded to the fabric by conventional high frequency welding techniques using a metal die 13.
• a layer 12 of PVC foam material may be sandwiched between the textile substrate 10 and the PVC sheet 3 to achieve a three dimensional effect.
• the applique according to the invention is readily formed and applied and has improved colour fastness and stability after repeated machine washings of the garment to which it is applied. Further, the applique has superior tactile properties to conventional appliques.
• polyamide fibres pre-dyed by conventional techniques gives the substantial advantages mentioned above.
• the fibres have improved light fastness, wet and dry rubbing fastness and improved abrasion resistance.
• the use of these fibres represents in particular a substantial improvement over fibres which are screen printed after application.
• the appliques of the invention may be used in high specification applications such as in the motor vehicle industry.
• Conventional appliques have not heretofore been used in such industries because of the disadvantages of conventional products and processes.
