Definitions

• crepe fabrics from synthetic yarns capable of shrinking when heated, including yarns of non-hydroxylated vinyl polymers.
• crepe yarns i.e. yarns producing the crepe, yarns based upon partially acetalised polyvinyl alcohol which have been given a crepe twist of at least 1000 turns per metre and which in their untwisted state do not shrink by more than in water at 100 C.
• the crepe is produced on fabrics containing these yarns by the action of hot aqueous liquids or vapours.
• partially acetalised polyvinyl alcohol polymers whose chain comprises at least 50% in number of CH CHOH-- units which polymers are acetalised to a sufiicient degree to make them insoluble in water at 100.
• the acetalising groups may be any of those known in the art, derived for example from formaldehyde or acetaldehyde.
• Either the warp or the weft or both may comprise the partially acetalised polyvinyl alcohol yarns, which may make up the whole of the fabric or may be used in association with yarns of another nature such as natural silk, wool, cotton, regenerated cellulose, etc. Some or all of such other yarns may themselves have a crepe twist, especially a twist of at least 1000 turns per metre, or they may have only a low degree of twist.
• Fabrics can be obtained in accordance with the invention which are very solid and regular. They are superior to crepe fabrics containing other synthetic or natural fibres, and they have just as good a handle as crepe fabrics formed of natural silk, while having higher wear resistance and higher resistance to photochemical degradation.
• Example I A fabric was produced in which the warp contained per centimetre 43 natural silk yarns having a crepe twist of 3200 turns per metre, arranged as 2 threads having a Z- twist and 2 threads having an S-twist, and in which the weft contained per centimetre 335 denier 20 filament partially acetalised polyvinyl alcohol yarns, with a crepe twist of 2800 turns per metre arranged as 2 picks of S-twist and 2 picks of Z-twist.
• the fabric was thereafter passed through a soap bath at 95 C. for de-sizing.
• a crepe georgette was constructed entirely of 35 denier, 25 filament, partially acetalised polyvinyl alcohol yarns with a crepe twist of 3000 turns per metre, the warp being made up of 2 threads of S-twist and 2 threads of Z-twist, and the weft of identical threads, with 2 picks of S-twist and 2 picks of Z-twist.
• Example III A warp consisting of partially acetalised polyvinyl alcohol, 3 5 denier, 20 filament, 60 turns per metre, was interwoven with weft threads of polyvinyl alcohol crepe twisted with 28:00 turns per metre, using 2 picks with S-twist and 2 picks with Z-twist.
• a crepe fabric comprising crepe yarns of an at least partly acetalised polyvinyl alcohol whose chain comprises at least 50% in number of CH CHOH units suflicient of which are acetalised to make said polyvinyl alcohol insoluble in water at C., said yarns having a crepe twist of at least 1000 turns per metre and being composed of fibres which, in their untwisted state, shrink by less than 5% in water.
• a crepe fabric comprising crepe yarns of an at least partly acetalised polyvinyl alcohol having sufiicient of the -CH CHOH units acetalised to make said polyvinyl alcohol insoluble in water at 100 C., said yarns having a crepe twist of at least 1000 turns per metre and being composed of fibres which, in their untwisted state, shrink by less than 5% in water.
• a crepe fabric according to claim 1 consisting wholly of said acetalised polyvinyl alcohol crepe yarns.
• a crepe fabric according to claim 2 consisting wholly of said acetalised polyvinyl alcohol crepe yarns.
• a crepe fabric according to claim l containing also yarns of a different material.
• a crepe fabric according to claim 2 containing also yarns of a different material.
• a crepe fabric according to claim 1 comprising also yarns of a different material having a twist of at least 1000 turns per metre.
