Title: Process for the production of crepe-like shrunken effects combined with colour-printed effects on textile materials
IPC: D06P5/00
Filed: 1949-07-27
Abstract: A colour-printed fabric exhibiting crepe-like shrunken effects is obtained by first printing a pattern of coloured stripes on the fabric and then shrinking stripe-shaped zones of the fabric parallel to the coloured stripes by means of caustic alkali solutions, the relationship between the coloured stripes and the zones to be shrunk being such that (1) when the width d of the fabric zones to be shrunk is equal to the interval c between every two such zones, the ratio of the pitch (c+d) of the zones to be shrunk to the pitch (a+b) of the colour-printed stripes, having a width a and spaced at intervals b, is substantially 2k where k is any integer, or (2) when d and c are unequal, the ratio d/c is equal to the ratio b/a and the ratio (c+d)/(a+b) is substantially equal to n/2 where n is any odd integer other than 1.  Such a relationship avoids the formation of undesirable moire effects. The fabric may be a lightweight cotton fabric or it may comprise fibres of natural and regenerated cellulose or fibres of natural cellulose and of polyvinyl compounds or polyamides.  The shrunken zones may be obtained by treating the fabric with a gum resist, subjecting the fabric to an all-over shrinking treatment, and then washing out the gum.  Alternatively, the back of the fabric may be printed with a water-insoluble lacquer, e.g. a cellulose nitrate solution, before treating with the shrinking agent.  The lacquered zones are given a permanent stiffness.  If desired the shrinking agent may be applied by direct printing. Alternatively, the fabric may be so woven that it contains zones of yarns that shrink in caustic soda solutions and zones of resistant yarns, e.g. it may contain zones of cotton yarns alternating with zones of polyvinyl or polyamide yarns or cotton or regenerated cellulose yarns which have been treated with formaldehyde, stearamido-methylpyridinium chloride, octadecyl-oxymethyl pyridinium chloride or other water-proofing agent.  In an example, a fabric containing mixed yarn of cotton and regenerated cellulose staple fibre in warp and weft is printed in a stripe pattern (width of stripes 0.5 mm., interval between stripes 1.5 mm.) with a vat dye. The fabric is steamed, and dried, and then printed with a thickened caustic soda solution in a stripe pattern (width of stripes 2 mm., interval 2 mm.).  The fabric is then acidified, washed and dried. Crepe-like effects of a changing vivid colour are obtained.  In another example, the fabric comprises a warp of cotton yarn, and a weft of alternating parallel zones of cotton yarn and formaldehyde-treated viscose rayon yarn.  In another example, the fabric comprises a warp of alternating parallel zones of nylon yarns and cotton yarns and a weft of cotton yarns, the width of the zones being 1.9 mm. and 3.2 mm., respectively.  The fabric is colour-printed in stripes running parallel to the warp, the stripes being 1.3 mm. wide with intervals of 2.1 mm.
