A process for forming crepe fabrics on a shuttleless loom is provided which includes temporary stabilization of highly twisted (e.g., 40-70 TPI) filament yarn. To this end, hot melt size is applied at a predetermined temperature in predetermined amounts (e.g., add-on of about 10.5-13.5%) immediately after twisting so as to reduce the liveliness of the yarn and to thereby permit it to be woven. After weaving, the yarn stabilization is reversed by a desizing operation. The fabric is subsequently heat treated to develop crepe characteristics.

Process for forming crepe fabrics and for temporarily stabilizing high

A method and apparatus for producing novelty yarn with an unusual configuration. An effect yarn is fed to a novelty yarn jet, and a core yarn is fed to a different yarn port in the same jet, the core yarn being maintained substantially taut. The combined core and effect novelty yarn is taken up from the jet and periodically (preferably pseudo-randomly) a pronounced variation in linear density is provided in the combined yarn. This linear density variation is accomplished by introducing a first fluid pulse into the jet at a first position to form a loop in the effect yarn, which loop extends substantially coincident with a portion of the core yarn, and then utilizing a second fluid pulse at a spaced position from the first pulse to impart a spiraling and/or rotating action to the loop of effect yarn to wind the effect yarn around the core yarn. Separate valves are associated with the fluid ports in the jet, and a numerical controller may be utilized for controlling the operation of the valves to produce the variations in linear density. The final novelty appearance of yarn and fabric from it is generated by backwinding and/or weaving the yarn from the take-up package.

Novelty yarn production

A method and apparatus for one step texturing and package preparation of high stretch continuous filament yarn for ultimate package dyeing. Continuous filament yarn is fed from a supply across a false twisting assembly, and a false twist is imparted thereto. The yarn is then passed over a roller and directed generally downwardly toward a takeup assembly including a dye spring. The yarn is overfed to the dye spring so that the yarn may relax completely and will have maximum skein shrinkage after dyeing. This is accomplished by passing the yarn through an air jet, resulting in an overfeed of up to 70-100 percent, which overfeed is not possible with conventional methods. The yarn package formed is soft, and may be package dyed according to conventional procedures.

High stretch yarn texturing, dyeing and package production

The present invention provides an apparatus for forming a textured air jet yarn by passing a yarn through texturing means whereby the yarn is false twisted and heat set in the twisted condition, passing the textured yarn through an air jet where the air is fed into the yarn at an angle of 45.degree.-75.degree. and passed cocurrently through the jet with the yarn to interlace the yarn and then collecting the textured, interlaced yarn.

Yarn interlacing air jet

The present invention provides a textured air jet interlaced yarn comprising a plurality of continuous synthetic thermoplastic filaments, the yarn being characterized by repeating sections of about 1/8-1 inch in length, each section being composed of a relatively open portion of bulky and lofty false twisted multifilaments and a relatively short node portion where the multifilaments are brought closer together and are interlaced and encircled. The disclosure also relates to a fabric made from the aforementioned yarn.
