ABSTRACT:
The invention relates to a textile support for reinforcing clothing or pieces of clothing.
The invention also relates to a method of manufacturing such a textile support, and to its applications.
Reinforcing textile supports are intended to give the required feel, flexibility and firmness to the clothing to which they are fixed.
U.S. Pat. No. 5,065,599 describes an interlining fabric which will facilitate the securing by basting of a second textile layer to the interlining. To this end, it proposes a fabric body which is warp knitted, and with floats at one surface thereof.
This document does not relate to an interlining incorporating a layer of nonwoven textile to meet the requirements in terms of weight and volume.
U.S. Pat. No. 3,992,904 describes a stitch-bonded nonwoven fabric comprising a web of fibers stitch-bonded by wales of chain stitch loops on one side of the fabric which are interconnected on the other side of the fabric by stitch laps.
This fabric is not suitable for reinforcing clothing but for furnishing, drape and dress.
Different proposals have already been made for producing thermobonding textile supports intended for interlining and incorporating a layer of nonwoven textile.
For example, FR-A-2 645 180 describes a product including a layer of nonwoven textile, a weft, a knitted thread ensuring the connection of the weft with the layer of nonwoven textile and a thermobonding adhesive layer.
The products proposed up until now do however not make it possible in all cases to meet the requirements in terms of weight, which must be low, volume which, on the other hand, must be high, firmness, elasticity and dimensional stability.
The invention therefore aims to remedy these drawbacks.
To this end, it proposes a textile support for reinforcing an item of clothing or pieces of clothing, in the form of a layer of nonwoven textile reinforced by one or more warp knit fabrics, the stitches of the knitted fabric or fabrics having floats on at least two columns of stitches.
According to other characteristics, the floats are produced on each row of stitches. As a variant, they are produced on one row of stitches out of two, or on one row of stitches out of three or four, or even more.
According to one embodiment, the textile support of the invention also comprises short-weft threads unwinding in the direction of the floats.
The short-weft threads do not participate in the formation of the stitch and their function is notably to increase the stability of the support.
According to yet another embodiment, the textile support of the invention also comprises a second warp knit fabric, the stitches of the second knitted fabric also having floats on at least two columns of stitches.
This second knitted fabric is preferably superimposed on the first knitted fabric and its function is notably to increase the volume of the textile support.
This second knitted fabric is produced from threads with compositions and/or yarn numberings identical to or different from those used for the first knitted fabric.
The second knitted fabric has floats identical to or different from those of the first knitted fabric.
For example, the first warp knit fabric has floats on two columns of stitches whilst the second warp knit fabric has floats on three columns of stitches.
The knitted fabric is produced from textured artificial or synthetic threads.
The textured synthetic threads comprise for example multifilament threads.
The number and yarn numbering per single ply of the filaments are generally chosen according to the resilience or elasticity, volume and flexibility required for the textile support. For example, the yarn numbering per single ply of the filaments can be between 1 decitex and 35 decitex.
The multifilament threads can comprise from 6 to 150 filaments.
The textures threads comprise for example threads of polyamide, notably polyamide 6 or 6.6, polyester or viscose and derivatives and/or mixtures of these products.
Texturing is obtained by using, for example, a conventional technique of texturing by false twisting or an air texturing technique.
The density of the knitted fabric is generally chosen according to the flexibility which it is wished to confer on the textile support and the yarn numbering of the threads used. The density of stitches is thus between 2 stitches per cm and 20 stitches per cm.
The invention also relates to a method of manufacturing a textile support intended for reinforcing clothing or pieces of clothing of the type in which:
a lap of nonwoven textile is formed,
the cohesion of the lap of nonwoven textile is reinforced with at least one warp knit fabric on a loom of the “warp” type the stitches of the knitted fabric having floats on at least two columns of stitches,
the textile support thus obtained is finished, during which the knitted fabric undergoes contraction,
optionally, a layer of thermobonding material is deposited on at least one of the faces of the textile support.
The invention also relates to the applications of the textile support of the invention, notably for the stiffening of clothing or pieces of clothing, such as jackets, shirt fronts, trousers, ties, shirts or the like, as well as clothing or pieces of clothing including at least one textile support according to the invention.
