Abstract: A carpet is tufted with a two-part primary backing. The upper, or face, backing is a conventional woven or non-woven polypropylene, and the lower, or back, backing is a stronger, open weave fabric. The tufts of yarn are sewn through both parts of the primary backing, which holds the parts together, and causes some of the back stitches to protrude for better coating with adhesive. The resulting carpet may be fully back coated, and may have a secondary backing adhered thereto. The lower backing prevents elongation, stretching and shrinking of the carpet during manufacture and subsequent processing.

Abstract translation: 地毯上装有两部分的主要背衬。 上或背面的背面是常规的编织或非编织聚丙烯，而背面或背面的背衬是较强的开放编织织物。 纱线的毛束通过主要背衬的两个部分被缝合，其将部件保持在一起，并且使一些背针突出以更好地用粘合剂涂覆。 所得到的地毯可以完全背面涂覆，并且可以具有粘附到其上的第二背衬。 下衬垫防止在制造和后续加工过程中地毯的伸长，拉伸和收缩。

Abstract: A bonded calcium carbide article that is solid and self-supporting is obtained by mixing granular calcium carbide with a suitable bonding agent. The resultant bonded calcium carbide article, which is easy and safe to handle, can be effectively and efficiently used as a sulfur scavenger in the refining of metals and metal alloys.

Abstract: A tufted carpet includes a primary backing having a back side and a face side, and a secondary backing. The carpet includes tufts of yarn sewn through the primary backing so as to be exposed on the face side and to form a plurality of back stitches on the back side. The yarn of the tufted carpet is a thermoplastic material having a yarn melting point. The secondary backing is a thermoplastic material in the form of a fluid-impervious film or a fabric having a softening temperature that is no lower than the yarn melting point, or a laminate having an inner and an outer layer, in which the outer layer comprises a thermoplastic material having a softening temperature that is no lower than the yarn melting point. A method for making such a tufted carpet includes the steps of bringing the secondary backing into contact with at least some of the back stitches on the back side of the primary backing, and heating the combination of the primary backing and the secondary backing to a temperature sufficient to adhere the secondary backing to the back stitches without melting the secondary backing.

Abstract translation: 簇绒地毯包括具有背面和面侧的主衬里和次背衬。 地毯包括通过主衬里缝合的纱线簇，以便露出在正面，并在背面形成多个背针。 簇绒地毯的纱线是具有纱线熔点的热塑性材料。 第二背衬是不透液膜形式的热塑性材料或具有不低于纱线熔点的软化温度的织物，或具有内层和外层的层压体，其中外层包含 软化温度不低于纱线熔点的热塑性材料。 用于制造这种簇状地毯的方法包括以下步骤：使第二背衬与主背衬的背侧上的至少一些背针接触，并将主衬里和第二衬垫的组合加热至温度 足以将第二背衬粘附到背针上而不熔化辅助背衬。

Abstract: A tufted carpet is made by tufting yarn through a primary backing including a first backing layer and a second backing layer. The first backing layer is formed of a woven, non-woven or plastic sheet material, or a composite of a woven or non-woven material and a plastic sheet material. The second backing layer comprises a leno weave, open weave, plastic net or plastic sheet material. The first backing layer and the second backing layer are arranged so that the first backing layer forms a first side of the primary backing and the second backing layer forms an opposite side of the primary backing. The tufts of yarn that are sewn through the primary backing are exposed on the first side of the primary backing for forming face yams, and also form a plurality of back stitches on the opposite side of the primary backing. At least a major portion of the back stitches secure the first backing layer to the second backing layer.

Abstract: A carpet including yarn pile extending from the face of a primary backing and a secondary backing bonded to the back of the primary backing has a thin film of liquid impervious thermoplastic material bonded either to the rear of the primary backing or to the rear of the secondary backing to provide a fluid barrier for preventing spills from seeping through to a floor beneath the carpet. The film is bonded to either backing by a hot melt thermoplastic adhesive or other non-aqueous adhesive. Additionally, the method of providing such fluid barrier for the carpet is disclosed.
