FR2879222A1 - Knitted fabric with loops on both sides for garments or cleaning materials is made in five sections - Google Patents

Abstract

The knitted fabric is made on an interlock loom in five sections: flat stitches on long needles, cylindrical stitches on long needles (3); flat and cylindrical stitches on short and long needles (4); flat and cylindrical stitches on short needles (5); flat stitches on short needles and cylindrical ones on long needles (6); and a system for freeing the loops. The latter can be in the form of dropping stitches and opening a shutter, or by the use of a destructible yarn which is removed chemically in a final operation and combined, for example, in a dyeing operation.

Description

The invention relates to a double-faced terry knit which will find

  especially its application in the textile industry of the mesh.

  In terms of fabrics and more particularly in the world of knits, there are many textures. However, when it comes to double-faced terry fabrics, only one side is affected by large size loops, the other side having only small loops. In the double-sided jersey, the loop on one of the faces is produced by returning the loop through the fabric, which explains the inequality of the sizes of loops.

  In addition, according to this technique the loops of the two faces are necessarily made with the same thread so the same material. There is no known manufacturing method on conventional circular loom for the production of fabrics bearing equal loops on both sides.

  The main object of the present invention is to describe a double-sided terry knit texture. This makes it possible to offer a great comfort of reach because the double loop of the same size forms a thick thermally insulating air mattress and a great hydrophilic power. Being a true double-sided fabric, the fis of the loops on each of the faces can be of different compositions.

  Another advantage of the invention is that it can be manufactured on a standard interlock knitting machine. The implementation is therefore extremely easy and the production costs relatively low. In addition, an interlock texture is much more elastic than a jersey texture, which makes it

More comfortable.

  The applications are multiple since in addition to clothing, the double-faced knit of the invention will also find uses in the industry for cleaning delicate parts thanks to its high absorbency It can advantageously replace several conventional cloths in terms of retention of liquid.

  By using for its manufacture a microfibrous material, it also offers a high dust-collecting power and it can be used on both sides. 35 Double-sided loop knit on interlock loom, characterized by the fact that it consists of five falls or rows of knitting: E Chain stitch on long needles, cylinder loads on long needles É Cylinder and tray stitch on short needles long needles É Loads on the tray on short needles stitches on the cylinder on short needles É Loads on the tray on short needles and stitches on the cylinder on long needles É Means of release of the buckle The invention will be better understood on reading the following description which however, is only indicative. It is accompanied by the following drawings in the appendix: FIG. 1 shows the placement of the long and short needles on the needle beds of the interlock craft; FIG. 2 schematizes the five falls forming the texture of the invention; double-faced loop that will find its application in hosiery.

  Among the multitude of knits achievable on circular looms, there is no known manufacturing process that allows the production of fabrics with equal loops on both sides.

  The object of the invention is to describe a means of production of such a knit that is feasible on conventional interlock loom, gifts with a very simple implementation.

  First of all the interlock craft will have to be mounted with alternating long and short needles as schematically represented in FIG. 1. The top line (1) represents the row installed on the cylinder and the bottom line (2). represents the line of needles installed on the plateau of the circular loom.

  Then according to the invention, the team is equipped with a set of five falls as shown in Figure 2. Those skilled in the art will recognize the mesh of an interlock craft.

  The assembly is as follows: • The chute (3) corresponds to the meshes on the plateau on long needles, loads on the cylinder on long needles É The fall (4) corresponds to the stitches in the cylinder and the plateau on 40 short needles and long needles The drop (5) corresponds to a load on the short-stitch needle plate with a short-needle cylinder 2879222 3 É The drop (6) corresponds to a load on the short-needle and long-needle needle stitch According to the present invention the chute (7) has means for releasing the loop to form the loop on the second face.

  The invention will disclose two means for obtaining this loop release in the fifth fall.

  First of all a mechanical process. According to this alternative, a mesh is created at the level of the fifth fall with opening of the valve needle. The loop is released to form. The disadvantage of this method is that it requires to work slowly with the circular loom. So the production is weak. In addition, the risks of wrong way are high.

  The other advantageous technique which constitutes a preferred mode of implementation of the invention consists in using a destructible wire for the fifth fall (7). Knitting is therefore classic. The trade is good and the risks of poor quality are low.

  The yarn is chemically destroyed in a subsequent knitting operation. It can for example be combined with the dyeing operation of the piece of fabric.

  By way of example, here is the composition of a double-sided terry knit fabric intended for producing a cleaning cloth with high absorbency: Drop thread (3): polyester / polyamide yarn multi-strand 178/2 dTex Fil chute (4 ): Polyester yarn 167 dTex 34 strands Thread yarn (5): Polyester / polyamide yarn stranded 178/2 dTex Thread yarn (6): Polyester yarn 167 dTex 34 strands Thread yarn (7): Polyvinyl Alcohol yarn (Kuralon) Others Embodiments of the present invention could also have been contemplated without departing from the scope thereof.
