[0050] 165dtex bicomponent PET / PTT fully drawn spun to produce a 2kg package size on a plastic dyed tube with dimensions 11.4"x3". %BE is 60%. The process conditions were established as follows:

[0051] Vapor pressure is 28psig

[0052] Feeding speed is 360ypm

[0053] 250% overfeed rate

[0054] Heberley "A" Series Ceramic Nozzles

[0055] Water fed from boiling water was 40ml / min.

example 2

[0057] A 167 dtex bicomponent PET / PTT stretch false twist texturized yarn was produced on a plastic dyed tube with dimensions 11.4"x3" to produce 2kg packages. %BE is 58%. The process conditions were established as follows:

[0058] Vapor pressure is 35psig

[0059] The feeding speed is 530ypm

Abstract

Processes for steam jet bulking of multicomponent yarns, yarns produced via these processes, packages of wound multicomponent yarns produced via these processes, and stretch fabrics and articles of manufacture of these yarns and stretch fabrics are provided.

Description

technical field [0001] The present disclosure relates to a process for the production of bulky multicomponent spun yarns and to products comprising multicomponent spun yarns produced by vapor texturing according to this process to obtain controlled stretch parameters in processed spun yarns. Background technique [0002] For applications requiring durability and compatibility with certain textile processing methods, it is desirable to produce stretch fabrics with the majority of the stretch being of non-elastic fiber origin. [0003] Non-limiting examples of fibers for these stretch fabrics include multicomponent spun yarns, eg, bicomponent filament spun yarns containing PET and PTT polymers. This conventional bicomponent spinning exhibits high shrinkage and retraction when heat is used to activate differential polymer shrinkage to form permanent loft. Fabric knitting and weaving processes utilizing these spun yarns are challenging because such large changes in spun length ...
