## Abstract

A scrim that is more readily recycled by grinding is disclosed and has a plurality of high tenacity fibers or yarns having a tenacity of at least about five (5) grams per denier and oriented in the warp direction and a plurality of low tenacity fibers or yarns having a tenacity of less than about four (4) grams per denier and oriented in the weft direction. In preferred embodiments, the low tenacity fibers or yarns comprise textured fibers or spun and undrawn fibers.

## Claims

### Claim 1

A scrim defined by warp fibers comprising high tenacity fibers and weft fibers comprising low tenacity fibers, wherein the weft fibers further define a selvedge.

### Claim 2 (depends on 1)

The scrim of claim 1, wherein the high tenacity fibers have a tenacity of at least about 5 grams per denier.

### Claim 3 (depends on 1)

The scrim of claim 1, wherein the low tenacity fibers have a tenacity of less than about 4 grams per denier.

### Claim 4 (depends on 1)

The scrim of claim 1, wherein the high tenacity fibers have a tenacity of at least about 7 grams per denier and the low tenacity fibers have a tenacity of less than about 3 grams per denier.

### Claim 5 (depends on 1)

The scrim of claim 1, wherein the warp fibers comprise yarns.

### Claim 6 (depends on 1)

The scrim of claim 1, wherein the weft fibers comprise yarns.

### Claim 7 (depends on 1)

The scrim of claim 1, wherein the weft fibers comprise textured fibers.

### Claim 8 (depends on 1)

The scrim of claim 1, wherein the weft fibers comprise textured yarns.

### Claim 9 (depends on 1)

The scrim of claim 1, wherein the weft fibers comprise spun fibers.

### Claim 10 (depends on 1)

The scrim of claim 1, wherein the weft fibers comprise spun and undrawn fibers.

### Claim 11 (depends on 1)

The scrim of claim 1, wherein the weft fibers comprise yarns comprised of spun fibers.

### Claim 12 (depends on 1)

The scrim of claim 1, wherein the weft fibers comprise yarns comprised of spun and undrawn fibers.

### Claim 13 (depends on 12)

The scrim of claim 12, wherein the weft fibers are formed into yarns.

### Claim 14 (depends on 1)

The scrim of claim 1, further comprising a nonwoven web laminated to said scrim.

### Claim 15 (depends on 1)

The scrim of claim 1, further comprising a nonwoven web of staple fibers laminated to said scrim by a needle punching process.

### Claim 16 (depends on 1)

The scrim of claim 1, further comprising a nonwoven web of staple fibers laminated to said scrim by a needle punching process, wherein the weft fibers comprise textured fibers.

### Claim 17 (depends on 1)

The scrim of claim 1, further comprising a nonwoven web laminated to said scrim, wherein said weft fibers comprise yarns comprised of spun and undrawn fibers.

### Claim 18 (depends on 1)

The scrim of claim 1, further comprising a nonwoven web of staple fibers laminated to said scrim in a needle punch process, wherein said weft fibers comprise yarns comprised of spun and undrawn fibers.

### Claim 19 (depends on 1)

The scrim of claim 1, further comprising a nonwoven web of staple fibers laminated to said scrim in a needle punch process, wherein said weft fibers comprise yarns comprised of textured fibers.
