Abstract
A process for imparting a variety of ranges in modulus, stretch and recovery characteristics into an elastomeric fill yarn and a rigid warp yarn stretch woven fabric. The high stretch/recovery properties, in the fill direction, is achieved by using a plurality of successive fabric forming operations, resulting in incremental stretch capacity from each successive operation. The fabric exhibits high stretch/recovery properties in the fill direction and rigid or extremely low stretch properties in the warp direction.
Claims1
A process for manufacturing a weft stretch woven fabric comprising the steps of:
- a. providing rigid warp yarn to a weaving loom
- b. providing fill yarn tensions discs to a weaving loom
- c. providing fill elastomeric core spun fill yarn to a weaving loom
- d. controlling the amount of stretch on the elastomeric fill yarn at the tension discs while pulling the fill yarn through the shed during weaving, and
- e. spacing the warp ends such that partial contraction between the interlacings in the fill direction occurs between the reed and the cut roll during weaving, and
- f. exposing the partially oriented fabric to steam, and
- g. washing said fabric with tension free wash equipment, and
- h. drying said fabric with tension free equipment, and
- i. subjecting the fully jammed fabric to a tensionless heat and pressure operation, whereby the resulting stretch capacity of the fabric in the fill direction meets or exceeds 90%, the modulus is within the range of 1 to 4, the recovery meets or exceeds the 90%, the growth is less than 10%.
