## Abstract

This invention pertains to a tire, a transfer hose, a hydraulic hose, a conveyor belt or a power transmission belt comprising a structural fibrous reinforcing component, the component further comprising spun staple yarn having a linear density corresponding to a cotton count of from 17/1 to 10/5.

## Claims

### Claim 1

A tire, a transfer hose, a hydraulic hose, a conveyor belt or a power transmission belt comprising a structural fibrous reinforcing component, the component further comprising spun staple yarn having a linear density corresponding to a cotton count of from 17/1 to 10/5.

### Claim 2 (depends on 1)

The component of claim 1, wherein the yarn is penetrated by a surface coating for promoting adhesion to rubber such that the coating comprises from 0.1 to 25 weight percent of the yarn plus coating.

### Claim 3 (depends on 1)

The component of claim 1, wherein the spun staple yarn has a linear density corresponding to a cotton count of from 10/2 to 10/4.

### Claim 4 (depends on 1)

The component of claim 1, wherein the yarn is a singles yarn comprising a blend of fibers.

### Claim 5 (depends on 1)

The component of claim 1, wherein the yarn is a blend of yarns that are twisted together to form a merged yarn.

### Claim 6 (depends on 1)

The component of claim 1, wherein the yarn is a sheath-core yarn comprising at least one continuous filament in the core and spun staple yarn in the sheath.

### Claim 7 (depends on 1)

The component of claim 1, wherein the spun staple yarn is aromatic polyamide, aromatic copolyamide, aliphatic polyamide, polyester, rayon, carbon, glass, modacrylic, polyolefin, acrylic, polyazole, liquid crystal polymer, cellulose, lyocell, polylactic acid, metal or blends thereof.

### Claim 8 (depends on 1)

The component of claim 1 in the form of a tire carcass, sidewall, belt, overlay, breaker, chipper, flipper or subtread.

### Claim 9 (depends on 2)

The component of claim 2, wherein the yarn is penetrated by a surface coating such that the coating comprises from 1 to 20 weight percent of the yarn plus coating.

### Claim 10 (depends on 6)

The component of claim 6, wherein the core material is inorganic.

### Claim 11 (depends on 7)

The component of claim 7, wherein the aromatic polyamide is para-aramid.

### Claim 12 (depends on 8)

The component of claim 8, wherein the yarn is penetrated by a surface coating such that the coating comprises from 2 to 15 weight percent of the yarn plus coating.

### Claim 13

A method of reducing tire noise in a vehicle by providing a component in a tire comprising spun staple yarn having a linear density corresponding to a cotton count of from 17/1 to 10/5.
