## Abstract

Method to produce a nonwoven needled fabric in which the needled fabric includes 15-30% of low melt nylon 6 and nylon 12 fusible fibers to aid in holding the nonwoven fabric together when passed through an oven to melt the fusible fibers and then allow them to cool and bind the fabric together.

## Claims

### Claim 1

A composite nonwoven fabric comprising a plurality of one type of high melt staple fibers blended with a blend of nylon 6 and nylon 12 low melt fusible staple fibers, said low melt fusible fibers having been melted and set to provide cohesion to said composite fabric.

### Claim 2 (depends on 1)

The fabric of claim 1 wherein said low melt fusible fibers comprise about 15-30% of the composite fabric.

### Claim 3 (depends on 2)

The fabric of claim 2 wherein said one type of staple fibers is nylon.

### Claim 4 (depends on 3)

The fabric of claim 3 wherein said one type nylon fibers are solution dyed.
