## Abstract

This invention relates to a base material for thermobonding interlining, constituted by a fabric or a weft knit of which at least the weft is made of synthetic yarns of large voluminosity, obtained by the air-jet texturization technique from at least two multi-filament yarns, namely a first core yarn for 20 to 40% by weight and a second effect yarn for 60 to 80% by weight, the overfeeding of the core yarn being included between 10 and 25% and overfeeding of the effect yarn at least 70%.

## Claims

### Claim 1

A base material for thermobonding interlining, constituted by a fabric or a weft knit comprising texturized synthetic yarns, wherein at least the weft of the fabric or of the weft knit is made of synthetic yarns of large voluminosity, obtained by the air-jet texturization technique from at least two multi-filament yarns, namely a first core yarn for 20 to 40% by weight and a second effect yarn for 60 to 80% by weight, the overfeeding of the core yarn being included between 10 and 25% and overfeeding of the effect yarn at least 70%.

### Claim 2 (depends on 1)

The textile base material for thermobonding interlining of claim 1, wherein the unitary filaments of the effect yarn have a count of between 1 and 3 decitex.

### Claim 3 (depends on 1, 2)

The textile base material for thermobonding interlining of one of claims 1 or 2 wherein, said base material being a weft knit, the percentage by weight of the weft yarn with respect to the warp yarn is at least 80%.

### Claim 4 (depends on 1, 2, 3)

The textile base material for thermobonding interlining of one of claims 1 to 3 wherein the core yarn presents a certain extensibility capable of giving the weft yarn obtained a residual extensibility of the order of 10 to 15%.

### Claim 5 (depends on 4)

The textile base material for thermobonding interlining of claim 4, wherein the core yarn is a yarn texturized by the false twist technique.

### Claim 6 (depends on 4)

The textile base material for thermobonding interlining of claim 4, wherein the core yarn comprises filaments based on elastothane.
