Abstract: A method of producing a colored narrow tape woven or knitted of a weft and a group of warp yarns, comprising: continuously moving the group of warp yarns along a longitudinal path through a dyeing station; coloring the group of warp yarns with a first dye at the dyeing station to a predetermined length to provide a first colored region; providing a noncolored region following to a trailing end of the first colored region; coloring the group of warp yarns with a second dye at the dyeing station to a predetermined length to provide a second colored region following to the noncolored region; and supplying the resulting warp yarns to a subsequent weaving or knitting station.
Abstract: In sizing and drawing of one or more textile filaments, particularly a warp sheet of multiple filaments, by successively conveying the filaments through a sizing bath, a driven squeezing mechanism, a differentially driven spaced drying roller, and a warp beam or other filament winding mechanism, the filaments are heated to a temperature of approximately 100.degree. C. and maintained in a predetermined moistened condition, e.g., by the application of saturated airborne water vapor, within the draw zone between the squeezing mechanism and the drying roller, in order to achieve a sufficiently elevated temperature for draw stretching of polyester filaments, particular POY and LOY filament, without premature drying and undesirable cracking of the sizing applied to the filaments.

Abstract: A polyethylene/polypropylene bag weaving machine includes a cooling system which eliminates the need for power lubrication. Ribbons being fed to the machine pass over a sponge located in a water tank, thereby moistening the ribbons and ensuring that they stay sufficiently cooling as they enter the weaving device.
Abstract: A yarn with a smooth coating is produced by coating a yarn with a thermoplastic material in the melt state, drawing the coated yarn through a heated dye, and cooling the coating.
Abstract: A filament bundle comprising a plurality of filaments is dyed level with a dye solution during continuous dyeing of the filament bundle by opening the filament bundle during dyeing in the horizontal and vertical direction by means of a driven roll having a sawtoothlike thread profile.
Abstract: Warp sizing compositions and starches useful therefor are prepared from high amylose starches which are converted to a water fluidity viscosity within the range of 65 to 80 and then reacted with an etherification reagent to achieve a nitrogen content of 0.5 to 0.9% (dry basis).
