Abstract

Improved process for the manufacture of a decorated textile composite 24, of the type in which: - first of all a hot-melt adhesive layer 5 is deposited onto a textile support base 3; - the metal face 18 of a metallised support film 16 is then applied onto this layer 5; - next, the assembly 20 is pressed hot under conditions which are sufficient to cause the softening of the hot-melt adhesive layer 5; - and, finally, the support film 16 is withdrawn, characterised in that, before applying the metallised film 16, inserts 8 are deposited randomly over the hot-melt adhesive layer 5. Application: decorated fabrics for haute couture.

Description

PROCESS FOR THE MANUFACTURE OF A DECORATED TEXTILE COMPLEX
AND COMPLEX THUS OBTAINED.

 The invention relates to a method for manufacturing a decorated textile complex; it also relates to a textile complex thus obtained.

 Many processes have already been proposed for producing decorated textile complexes, in particular fabric-based, with the most diverse elements such as feathers, straws, etc.

 However, fashion demands more and more new and original effects all the time.

We already know a process which consists
- first of all, to deposit on a textile backing a heat-bonding layer
- then, to apply on this layer the metal face of a metallized support film
- then to press the whole hot under conditions sufficient to cause the softening of the fusible layer
- finally, to remove the support film.

 This process, although widely used, gives limited effects and often requires depositing the adhesive by screen printing.

 The invention overcomes these drawbacks. It relates to an improved process defined above which is characterized in that before applying the metallized film, inserts are deposited at random on the fusible layer.

Advantageously, in practice
- the inserts are made up of feathers, glitter, textile blades, pieces of fabric, paper, pieces of raffia or strips
- after having deposited the inserts, but before applying the metallized film, a loose networked fabric is deposited on these inserts, such as a gauze or a tulle in this way, the metallic particles of the metallized film will not take on the glue only in the mesh of the network and outside the inserts
- the support base is a non-woven tablecloth in the form of cotton wool or a veil or a light fabric;
- the adhesive layer is a heat-bonding mesh, in particular made of polyamide copolymer
- the pressing operation is carried out hot by passing through a heated calender.

 In other words, the invention is complementary.

ment of the known process set out in the preamble:
- depositing inserts on the adhesive layer, then applying the metallized film, which after hot pressing, leads to fabrics whose bottom is metallized and on which the non-metallized inserts stand out
- As a variant, after having deposited these inserts, a loose fabric is applied such as a gauze, so that the bottom is metallized only in the meshes of this gauze and that the inserts are not metallized.

 Thus, the invention consists in carrying out metallization reserves by interposing inserts bonded to the bottom and / or reserves resulting from the addition of a gauze which in turn leads to additional reserves.

 The manner in which the invention can be implemented and the advantages which ensue therefrom will emerge more clearly from the following exemplary embodiments, given by way of non-limiting example, in support of the single appended figure which schematically represents, in section, an installation. according to the invention.

Example 1
In known manner, between two rollers in tangential contact (1) and (2), a fabric (3) is drawn, drawn from a beam (4) and a fusible mesh (5) made of hot-melt copolyamide unwound from a roller (6). On this set (7), feathers (8) contained in a tank (9) are deposited at random.

 On this first assembly designated by the reference (10), a woven gauze (12) is unwound from (11) unwound from a roller (13).

 On the second assembly obtained, designated by the general reference (14), a metallized film (16) is unwound from (15) unwound from a roll (17), taking care that the metallized face designated by the reference (18) is in contact with the inserts (8) and the gauze (12).

 The third assembly obtained designated by the general reference (20) then passes between the two rollers (21, 22) of a calender heated for example to 1600C. This grille has, if necessary, several rollers. This causes the softening of the fusible mesh (5) on which the inserts (8), the gauze (12) and the metal layer (18) adhere.

 In known manner, at the outlet of the calender (22), the support film (16) is separated, which is received at (23) from the new finished complex obtained (24) which is received at (25).

 This decorated textile complex (24) therefore consists of the stack of a support base (3), a heat-bonding layer (5), inserts (8) deposited at random, a layer of gauze (12 ) and glitter from the tearing of the metallized film (18).

Example 2
The assembly (7) of Example 1 is replaced by a commercial complex consisting of a cotton wool coated on its upper face d - r, one thousand points of heat-adhesive glue. The deposit of gauze (12) is eliminated and the metallized face (18) of the film (16) is applied against the fusible face of the wadding. We pass the whole in the same heating grille. A wadding is thus obtained, one of the faces of which has non-metallized glued inserts which stand out against a metallized background.

 The textile complexes according to the invention are essentially characterized by the great possibility of obtaining very new, varied and sought-after effects. In this way, they are ideal for haute couture.
