(54) COMBINED KNITTED FABRIC AND PROCESS FOR ITS PRODUCTION
(71) We, HEPATEX AG, a Swiss Com- pany of CH-9630 Wattwil, Switzerland, do hereby declare the invention, for which we pray that a patent may be granted to us,
and the method by which it is to be performed, to be particularly described in and by the following statement: The present invention relates to a combined knitted fabric and to a process for its production.
Textile articles are known which consist of top and bottom woven or knitted layers of fabric and of an intermediate layer of nonwoven fabric or the like, the fabric layers being permanently fixed together by quilting.
Such textile articles are mainly used in the
wearing apparel industry.
Furthermore it has been proposed in
Patent Specification No. 722770 to provide an interlock fabric consisting of elastic yarns and inelastic yarns, the inelastic yarns forming two surface layers of the fabric while
the elastic yarn, consisting of a covered rubber thread with a stretch of the order of
300 to 400 percent, is incorporated in a straight and stretched condition between the surface layers.
In another proposal in Patent Specification No. 1148086, a knitted fabric consists of a face fabric and a bottom fabric knitted
together at selected intervals with a layer
of yarns or rovings inserted between the face and bottom fabrics so that a quilted pattern is formed. The face and bottom fabrics are knitted from continuous filament synthetic yarns, preferably textured or "stretch" yarns. The inserted material most preferably consists of crimped or bulked acrylic fibre yarns.
It is the purpose of the present invention to provide a similar textile article, in which the spaces between the face and bottom fabrics are particularly effectively filled in such a way as to improve the heat insulation provided by the combined knitted fab
ric.
The combined knitting' fabric according to the invention comprises a top face knitted fabric, a bottom face knitted fabric, at least
one of said knitted fabrics providing, tuck stitches or loops connecting said knitted fabrics together at spaced locations defining between said stitches free spaces between said top face fabric and said bottom face fabric, and filler yarns consisting of textured synthetic filament yarns inserted between said top face fabric and said bottom face fabric and bulked optimally in a finishing treatment to expand and fill said spaces thereby producing raised areas in relief on at least one of said knitted fabrics.
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 face fabric may contain at least one elastic textured yam of synthetic material. In particular 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 yams.
The textured synthetic filament yams filling the spaces between the top face fabric and the bottom face fabric which is bulked optimally to provide raised areas in relief in the top and/or bottom surface of the combined knitted fabric has been found surprisingly, particularly in the case of falsetwist textured yarns of polyamides and polyesters, but also synthetic yarns textured according to the stuffing box or the air-jet process to 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 yam ends each consisting of synthetic fibers of different shrinkabilities.
For the production of the combined knitted fabric a circular knitting machine con sisting of cylinder and dial of conventional construction (double jersey jacquard) may be used. The top face fabric may be knitted on the cylinder knitting system and the bottom face fabric may be knitted on the dial knitting system. The connection of the two knitted fabrics may be realized particularly 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 produce the bottom face fabric.
These tuck stitches lie on the inside of the top face fabric and are 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 jacguard device. The yarn filling these spaces can be inserted by means of a special thread guide. Since this yarn does not form any loops, its titer may be essentially coarser than that of the 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.
In order that the invention may be clearly understood and readily carried into effect by those skilled in the art, examples of the invention are hereinafter described in more detail with respect to the accompanying diagrammatic drawings wherein:
Figure 1 shows a yarn path for a combined knitted fabric described in the following Example 1;
Figure 2 shows a yarn path for a combined knitted fabric described in the following Example 2;
Figure 3 shows a yarn path for a combined knitted fabric described in the following Example 3.
EXAMPLE 1
A false-twist textured yarn a of polyamide 6.6 with the titer dtex 110f34x2 is inserted in a cylinder knitting system with all needles 1 in action to produce a top face fabric in a single jersey knit (right and left stitches). Furthermore, an identical falsetwist textured yarn b is inserted in a dial knitting system with all needles 2 in action to produce a 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 yam feeder a false-twist textured yarn c of polyamide 6.6 with the titer detex 11 0f34 x 6 is inserted between the cylinder needles 1 and the dial needles 2.
The yarn c does not form any stitches but fills the spaces between the top face fabric and the bottom face fabric. In the 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 by subsequent treatment the combined knitted fabric has relieved parts (i.e., raised areas in relief) on the top surface as well as on the bottom surface.
During the following finishing treatment the yarn c bulks and fills the spaces between the top face fabric and the bottom face fabric to produce the relieved areas.
EXAMPLE 2
Two air-textured polyester yarns h, i having different colours and a titer dtex 200f64 x 1 are inserted into two cylinder knitting systems operating simultaneously.
In one cylinder knitting system yarn h is knitted with selected needles 1 in a pattern controlled by a jacquard device associated with the cylinder. In the other cylinder knitting system the yam i is knitted with the remaining needles 1 to produce a top face fabric in a single jersey knit. A false-twist textured yarn k of polyamide 6.6 with the titer dtex 1 10f34 x 2 is inserted in a dial knitting system with all needles 2 in action to produce a bottom face fabric in a single jersey knit. The yarn k forming at the same time tuck stitches kl. 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 shrinkabilities 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 fabric has relieved parts on the top surface.
EXAMPLE 3
A false-twist textured yarn a of polyamide 6.6 with the titer dtex 78f20x2 is inserted in a cylinder knitting system 1 with all needles in action to produce a top face fabric in a single jersey knit. Furthermore a false-twist textured yarn d of polyamide 6.6 with the titer dtex 78f20 x 2 is inserted in a first dial knitting system and knitted on needles 1, 3, 5, 7 etc. (needles 2, 4, 6 etc. being out of action). In a second dial knitting system a cotton yarn f Nm 50 is inserted 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 dl 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 110f34x2 are inserted as filling material.
By wet treatment in the following dyeing and finishing of the combined knitted fabric the yarn g bulks and fills the spaces between the top face fabric and the bottom face fabric so that the combined knitted fabric has relieved parts on the top surface as well as on the bottom surface.
