Abstract

Abstract A knitted fabric and a process for its production are disclosed.
The fabric consists of a top face fabric and a bottom face fabric knitted on the cylinder and dial knitting systems respectively of a circular knitting machine. The fabrics are connected by tuck stitches made on selected needles in a pattern by means of a jacquard device on the cylinder. A yarn that forms no loops is inserted between the cylinder and dial by a thread guide so as to fill the spaces between the top and bottom face fabrics.

Description

~: "

The present invention relates to a combined knitted fabric and to a process for its production.
Textile articles are known which consist of two woven or knitted layers of fabric and of an intermediate layer of non-woven fabric or the like, the fabric layers being permanently fixed to one another by quilting. Such textile articles are mainly used in the wearin~ apparel industry.
It is the purpose of the present invention to provide a similar tex-tile article the production of which is less expensive as it can be pxoduced on a knitting machine in one operation.
The combined knitted fabric according to the invention consists of a top face fabric and a bottom face fabric which are connected with each other ~ .
according to a pattern by tuck stitches or loops whereby free spaces are formed between said top face fabric and said bottom face fabric and ls characterized in that at least one yarn forming no loops and consisting of textured syn-thetic filamont yarns is inserted betwoen said top faco fabric and said bottom face fabric said yarn bulking to fill the spaces between said top face fabric and said bottom face fabric to produce relieved portions on at least one of the top and bottom surfaces of said combined knitted fabric.
Optimally, the yarn is bulked in a finishing treatment subsequent to knitting.
The top face fabric and the bottom face fabric may each consist of a , single jersey knit with right and left stitches. The top face fabric and/or the bottom ~ace fabric may contain at least one elastic textured yarn of syn-thetic material. Part;cularly false-twist textured yarns of polyamides and polyesters, but also synthetic yarns textured according to the stuffing box or the air-jet process are suitable. Furthermore the top face fabric and/or the --bottom face fabric may contain non textured yarns of synthetic material as well as yarns of natural and/or synthetic staple fibers, such as cotton yarns.
It has been found surprisingly that textured yarns of synthetic mate:rial, particularly false-twist textured -- 1 -- ~, . . .

yarns of polyamides and polyesters, but also synthetic yarns textured accord-ing to the stuffing box or the air-jet process are suitable as they bulk optimally in the following finishing step and entirely fill the spaces. In completely bulked condition, these yarns enclose very much air and improve the insulation power of the combined knitted fabric. Thereby, in spite of `
the complete filling of the spaces, the square meter weight of the combined knitted fabric remains relatively low.
Furthermore the yarn filling the spaces may as well be a plied yarn of different yarn ends each consisting of synthetic fibers or filaments of different shrinkability.
According to one aspect, the process for the production of the combined knitted fabric comprises the steps of providing stitches connecting a top ace knitted abric and a bottom face knitted fabric together at spaced locations defining between said stitches free spaces between said top face fabric and said bottom face Pabric, inserting between said top face abric and said bottom face fabric unbulked textured synthetic yarn and bulking said yarn in a heat finishing treatment to expand and fill said spaces thereby producing raised areas in relief on at least one of said knitted fabrics.
According to another aspect, the process is characterized in that on a circular knitting machine consisting of cylinder and dial of conventional construction (double jersey jacquard) a single jersey top face fabric is knitted on the cylinder knitting system and a single jersey bottom face fabric is knitted on the dial knitting system, the connection of the two knitted fabrics being realized by tuck stitches on selected needles in a pattern by means of a jacquard device on the cylinder, i.e. on those knitting systems of the dial which produces the bottom face fabric, and that the yarn filling the spaces between the top face fabric and the bottom face fabric is inserted between the cylinder and the dial by means of a thread guide and is adapted to be bulked optimally in a following finishing treatment.
The tuck stitches lie on the inside of the top face fabric and are ~ - 2 -:, ,.;.: , . :

~9~15 therefore not visible. If, instead of the tuck stitches, loops are formed by selected cylinder needles in a pattern, these loops appear on the surface of the top face fabric. In this way additional pattern effects can be achieved when using different and/or differently coloured yarns for the top ~ -face fabric and the bottom face fabric.
By the described process, spaces are formed between the top face fabric and the bottom face fabric, the size of which can be controlled at choice by means of the jacquard device. Since the yarn filling these spaces does not form any loops, its titer may be essen~ially coarser than that of the - 2a -t~J

yarns which form the top face fabric and the bottom face fabric. This filling yarn is fixed more or less only by said tuck stitches or loops so that its full volume can be developed.
Four examples of the invention are hereinafter described in more de-tail with respect to the figures of the drawings wherein:
Figure 1 shows a yarn path for the combined knitted fabric described in example l;
Figure 2 shows a yarn path for the combined knit~ed fabric described in example 2;
Figure 3 shows a yarn path for the combined knitted fabric described in example 3;
Example 1 A false-twist textured yarn a of polyamide 6.6 with the titer dtex 110f3~x2 is inserted ln the cylinder knitting system with all needles I in action to produce the top eace Eabric in a single jersey knit ~rlght and left stitches). Furthermore, an identlcal false-twist textured yarn b is inserted in the dial knitting system with all needles 2 in action to produce the bottom face fabric in a single jersey knit. At the same time tuck stitches b' are formed with selected cylinder needles in a pattern to connect the top face fabric and the bottom face fabric with each other. By means of a yarn feeder a false-twist textured yarn of polyamide 6.6 with the titer dtex 110f34x6 C is inserted between the cylinder needles 1 and the dial needles 2. The yarn c does not form any stitches but is filling the spaces between the top face fab-ric and the bottom face fabric. In case of the same stitch density in the knitting systems on the cylinder and on the dial the spaces between the top face fabric and the bottom face fabric are filled by the yarn c in such a way, that the combined knitted fabric has relieved parts on the top surface as well as on the bottom surface.
Example 2 On two cylinder knitting systems which are in working position two ' - , : . . , , 9~

air-textured polyester yarns h, i having different colours and a titer dtex 200f64xl are inserted. On one knitting system yarn h is knitted with selected needles in a pattern by means of the jacquard device of the cylinder. On the other knitting system the yarn i is knitted with the remaining needles to pro-duce the top face fabric in a single jersey knit. A false-twist textured yarn k of polyamide 6.6 with the titer dtex llOf34x2 is inserted in the dial knit-ting system with all needles 2 in action to produce the bottom face fabric in a single jersey knit. The yarn k forming at the same timethetuck stitches k'.
Between the cylinder needles 1 and the dial needles 2 a plied yarn e of three ends each having a titer Nm 40 and consisting of filaments of polyacryl with different shrinkability is inserted. During the following finishing treatment the yarn e bulks and fills the spaces between the top face fabric and the bottom face fabric so that the combined knitted fabrlc has relieved parts on the top surface.

~ ` , .
A false-twist textured yarn a of polyamide 6.6 with the titer dtex 78f20x2 is inserted in the cylinder knitting system 1 with all needles in action to produce the top face fabric in a single jersey knit. Furthermore a false~twist textured yarn d of polyamide 6.6 with the titer dtex 78f20x2 is inserted in the first dial knitting system and knitted on needles 1, 3, 5, 7 etc. ~needles 2, 4, 6 etc. being out of action~. In the second dial knitting system a cotton yarn f Nm 50 is insertecl and knitted on needles 2, 4, 6, 8 etc. (needles 1, 3, 5, 7 etc. being out of action). Complete stitch ranges are so formed to produce the bottom face fabric in a single jersey knit. At the same time tuck stitches d' are formed with selected cylinder needles in a pattern to connect the top face fabric and the bottom face fabric with each other. Between the cylinder needles 1 and the dial needles 2 one or more false-twist textured yarns g of polyamide 6.6 with the titer llOf34x2 are in-serted as filling material.
