Abstract: The invention provides a novel loom and method for weaving fabrics in which at least the weft comprises stiff strands for example in the form of tapes or bands. The weft strand (41) is frictionally gripped at one side of the warp array (40) and intermittently pushed through the shed to insert successive lengths of weft. In a preferred modification, a hollow guide (22) is advanced through the shed in the opposite direction to the pushing of the weft strand, the free or previously severed end of the strand is pushed into the hollow guide, for example by friction wheel drive (3),(31) mounted on sley (13), and the guide is retracted in the same direction and at the same time as the strand is pushed through the shed, such that the free end of the weft is inside the guide while it passes through the shed.

Abstract: A machine and method to operate the machine to provide a plurality of valve-like perforations in the rubber-like backing of a nap mat or carpet by delivering the nap mat or carpet to and under a spiked roll. The machine includes a sensing device to ensure the leading and trailing edges of the nap mat are not perforated by the spiked roll.

Abstract: A method is disclosed for heat treating textile substrates wherein a substrate may be dyed in pattern configuration and, optionally, thermally modified to produce visual surface effects in the pattern areas in perfect registry. Dye is applied to the textile substrate, and optionally dried, without being fixed. Heat is selectively applied in pattern configuration to the substrate. The heat is sufficient to fix the dye in pattern configuration, at a pre-determined level of fixation, and may also be sufficient to cause thermal shrinkage or other thermally-induced physical modification to the substrate, also in pattern configuration. Unfixed dye may then be removed, leaving a pattern-dyed substrate which, optionally, may have physically modified areas in perfect registry. A mixture of dyes having different fixation energy levels may be used for multiple color effects.

Abstract: Pressure control system in which the pressure in a sealed vessel is continuously measured along with the temperature of the treatment fluid to maintain a predetermined pad pressure in the treatment vessel to prevent boil off or flashing of the treatment liquid.

Abstract: A floor covering such as a nap mat or carpet of washable type comprises a rubber or plastic back, wherein the nap or tufts is/are fastened in the back material. The floor covering has means for increasing the drain of liquid from the nap when the floor covering is subjected to the influence of a force, such as a pressing force, a centrifugal force, and/or a pressure difference between the front and rear side of the floor covering. This means may be a normally closed perforation of the back material and/or an intermediate tissue via which the nap is secured to the back material. Preferably the intermediate tissue is a non-woven material, mainly consisting of synthetic fibres having a weight of 100-300, preferably 250 g per m.sup.2, a fibre thickness of 5-30, preferably 8 decitex, and a tissue thickness of 1-5, preferably 2 mm. Thereby a nap mat or carpet is achieved having a short drying time and/or provides a small drying energy consumption after washing.

Abstract: A hot melt adhesive bonded pile fabric is provided which comprises a liquid permeable base layer; a pile forming yarn adjacent to the base layer in pile forming fashion but not tufted through the base layer; the pile forming element having been bonded to the base layer by means of a hot melt adhesive applied to the back of said base layer. A method and apparatus for making fusion bonded, pile fabrics are also provided.

Abstract: A method is disclosed for permanently patterning a textile fabric with a visually pleasing random-appearing network of line segments, as well as the fabrics produced thereby. The fabric is preferably calendered on at least one side, then packed into a heated chamber via a multi-stage folding or pleating process. The packed fabric is retained in the heated chamber a sufficient time to heat set the network of creases generated by the packing process. The fabric may then be dyed; creased portions of the fabric appear more saturated with dye.

Abstract: A method is provided for producing a di-acetal of sorbitol and an aromatic aldehyde wherein an aqueous solution containing a catalytic amount of a mineral acid and sorbitol is formed. Thereafter, an effective amount of an aromatic aldehyde such as benzaldehyde is incrementally admixed into the homogeneous aqueous admixture containing the sorbitol at a rate sufficient to allow a substantially spontaneous reaction to occur between the D-sorbitol and aromatic aldehyde; thus, forming an aqueous slurry containing crude di-acetal, e.g., dibenzylidene sorbitol. The amount of aromatic aldehyde employed is that amount sufficient to provide a molar ratio of D-sorbitol to aromatic aldehyde of from about 1:0.75 to about 1:1.75. Thereafter, the aqueous slurry is neutralized, and crude di-acetal is removed from the liquid phase and washed with water to remove mono-acetal impurities, e.g., monobenzylidene sorbitol.

Abstract: A plurality of jet gun bars are spaced apart along the path of travel of a textile material and responsive to pattern data to form patterns on the material. Each gun bar stores and supplies different color dyestuff to color the material. A computer, on each periodic request, supplies pattern data to a predetermined number of gun bars, thereby providing dyestuff to different pattern lines for each request. During a change from printing one pattern to printing another different pattern, for each such request the computer provides data for the other pattern to a first predetermined number of gun bars and data for the one pattern to a second predetermined number of gun bars subsequent to the first number, thereby simultaneously completing the printing of the one pattern and starting the printing of the other pattern.
