Abstract

DC60 Modified Secondary Lining (20) for Carpet (50) consists of a secondary linen lining (15) and a fiber filling (21) which are combined with the secondary lining to form the modified lining, providing a soft front (51) opposite to the front (52) represented by the linen, without interruption by the linen. Carpet (50) consists of the front threads (11), the primary lining (12), the front threads are clustered in the primary lining, the modified secondary lining (20) is attached to the primary lining, and the bonding material (14) connects the front threads to the primary lining and the primary lining to the secondary lining. The modified secondary lining (20) consists of a secondary linen lining (15) and a fiber filling (51) which form the underside of the carpet. The soft face that forms a barrier is not interrupted by the linen underlay and prevents the outflow of any adhesion material from the underside of the carpet. A method for the fabrication of a modified secondary carpet underlay (20) consists of selecting a secondary linen underlay (15) and a fiber filling (21), connecting the two fabrics to form a modified secondary carpet underlay (20) that provides a soft face (51) opposite to the face (52) represented by the linen underlay, without being interrupted by the linen underlay, and heating such modified fabric sufficiently to remove all significant (45) loose fibers protruding from the soft face. This invention also provides a method for the fabrication of carpets. A modified secondary underlay (20) for carpets (50) consists of a secondary linen underlay (15) and a fiber filling (21) that have been combined with the secondary underlay to form the modified fabric as described above. The carpet (50) is constructed with a soft front (11), contrasting with the front (52) represented by the linen, without interruption by the linen. The carpet (50) consists of the front (11), the primary underlay (12), the front is clustered within the primary underlay, a modified secondary underlay (20) attached to the primary underlay, and an adhesive (14) bonding the front to the primary underlay and the primary underlay to the secondary underlay. The modified secondary underlay (20) consists of the secondary linen underlay (15) and a fibrous filling (51) forming the underside of the carpet. The soft front forms an uninterrupted barrier by the linen underlay and prevents the outflow of any adhesive from the underside of the carpet. The method for constructing carpet underlays is described below. The modified secondary carpet backing (20) consists of selecting a modified secondary carpet backing (20) that provides a soft front side (51) opposite to the front side (52) represented by the linen backing, without being interrupted by the linen backing, and subjecting the modified fabric to sufficient heat to remove all significant (45) fibers protruding from the soft front side. This invention also provides a method for the manufacture of carpets.
