Title:
METHOD OF RENDERING A FABRIC ELASTIC BY MEANS OF CAUSTIC TREATMENT AND RELAXATION, MACHINE FOR PERFORMING SAID METHOD AND FABRIC THUS OBTAINED
Document Type and Number:
WIPO Patent Application WO2005019516
Kind Code:
A3
Abstract:
The invention relates to a method of treating a fabric involving metal peroxide impregnation. The invention is characterised in that a fabric, e.g. pre-bleached and/or desized hydrophilic fabric having a weft (or inversely a warp) comprising natural or synthetic cellulosic fibres, is subjected to the following: impregnation (I) in a metal peroxide leaving the weft (or inversely the warp) free for a period necessary for the swelling of the fibre forming the weft (or inversely the warp) of the fabric and for the modification of the cellulose; at least one relaxation operation without weft (or inversely warp) tension with the passage of air, during which the weft (or inversely the warp) swells and takes the form of a spring, following shrinkage; at least one rinsing operation; at least one washing operation; and at least one squeezing operation. The invention also relates to the elastic fabrics thus obtained and to the machines used to implement said method.
