Abstract

The invention relates to a new printed textile article presenting pearly and iridescent coloured effects, wherein said article is produced from a fabric constituted of two different textile materials reacting differently towards the printing dyes, said fabric being produced in a construction selected from the woven, warp knitted or weft knitted constructions with which a velvet-type front and a plain back are obtained, the back being constituted, for a major part, of yarns showing a good receptivity to the used dyes whereas the pile of the front is made from yarns showing no receptivity towards said dyes, the printing of said fabric being performed on the back of the article.

Description

SPECIFICATION New printed textile article The present invention relates to a new printed textile article, and more particularly to a woven or knitted fabric, with iridescent or pearl coloured effects.

The manufacture of printed fabrics (woven or knitted) is a very old techniquewhich calls on numerous methods, either manual or mechanised and, performed in continuous or discontinuous manner. In general, in all methods, the printing is performed on the face of the fabric, the different colours of the pattern to be printed being capable if necessary to interpenetrate to the extent of the wanted effects.

Different solutions have also been proposed in order to obtain with the modern printing techniques (screen-printing, roller-printing, transfer-printing), effects which imitate those obtained with the very old techniques known as "warp-printing", "hand-painted" as described in particular in French Patent 2,363,448. According to said document, such effects are obtained not only with a very specific printing technique (transfer-printing) ofwhich the printing design is so devised and studied that the pattern presents parts where the colours interpenetrate, but also with a fabric in which the warp and the weft are made of a textile material which does not react in the same way towards transfer-printing dyes, one of the constituents ofthe fabric not being receptivetosaid dyes.

The teachings of this document, on the one hand, do not really induce anyone to applying this technique to the decoration of other articles than fabrics (for example knitted fabrics) and, on the other hand, they do not suggestthat itwould be possible to obtain a pearly or iridescent effect.

Now it has been found, and this is precisely the object of the invention, that it is possible to obtain a fabric giving such a pearly or iridescent effect, by using any one of the cloth-printing techniques known heretofo re, p rovided th at, fi rst the pri nti ng be carried out in a very precise way, and second, that the cloth being printed-on not on ly contains different textilematerialswhich do not all havethesame reaction towards the printing dyes, but also that it is produced in a very specific construction, namely a construction selected from the woven or knitted fabric construction with which a velvet type front and plain back are obtained, the back being constituted, for a major part, of yarns showing good receptivity towardsthe dyes used, whereasthe pile on the front is made from yarns showing no receptivity to the dyes.

Moreover, according to the invention, and contrary to normal practice, the printing is performed on the backofthe article instead of on the front.

Also, the basic fabric will be so produced thatthe pile is gray or white-coloured (or else very light-coloured),thefound'ation being also white or light-coloured.

Any type oftextile materials will be suitable as raw materials for producing an article according to the invention, for example: rayon, acetate, triacetate, acrylics, polyamides, polyester, polypropylene, cotton, wool (either pure or blended, with continuous yarns or spun yarns),the material being, however, according to the invention, selected so that afterthe production of the support, the back (smooth) and the front (pile side) are such that when printing on the back, the dye used does not rise through to the material forming the pile.

Among suitable knitting construction for producing the textile support, there are: -in the case of a circular knitting machine: knitting constructions for making loops or velvet pile, such as for example tip-sheared pile, the shearing being carried out on the machine, - in the case of a single- or double-bed warp knitting machine or Raschel machine: knitting constructions for making velvet piles, nappping, plain orcrushed panne, -in weaving: constructions for producing velvet (warp orweft).

The following example is given by way of indication and non-restrictively to illustrate the invention.

Example: According to the invention, a warp knitted fabric is produced on a 3-bar Karl Mayertype machine of British gauge 28.

Threading of the bars of the machine and their basic repeats are as follows: - bar 1: bar fully threaded with polyamideyarns 6-22 Dtex/l -1.0/2.3 lap - bar 2 : barfully threaded with polyamide yarns 6-22 Dex/1 -1.2/1.0 lap - bar 3: bar fully threaded with triacetate 66 Dtex/30 - 5.6/1.0 lap.

The knitted fabric, coming off the machine, is subjected to a napping operation on its front (satin side produced with triacetate yarns) in order to form the pile. The gray fabric is thereafter sheared in the conventional manner and subjected to a bleaching treatment and finally to a setting treatment.

Having done this, a coloured pattern is printed according to the registered printing technique on the back of the knitted fabric, the dye being selected from dyes only attaching the polyamide.

After printing,thearticle has, on itsfront, a pearly effect which is visible by transparency, the pile of the article remaining dyeless.

The articles produced as described hereinabove may be used in a large number of fields, such as clothing, upholstering (seats, curtains,...) or any other equivalent applications.

It is also possible, by adapting of course the density of the articles with respect to those described in the illustrated example, to use them for producing slippers, shoes, wall-coverings, or decorative coverings for motorcars, planes, trains, etc...
