Weaving of seersucker fabrics comprises applying heat to the upper level of the warps in the shed followed by cooling before reaching the healds to reduce their module of elasticity

摘要

During the weaving of a fabric at a loom, the warps (3) are heated at the point where the shed is opened, followed by cooling of the warps in the shed before they reach the healds (7,8). The heating is applied only to a part (34) of the warps in the shed. Downstream of the back rest roller (4), the warps are divided into two levels (33,34) to form the shed. The upper warp level (34) is heated by a plate (20) to a sufficient temperature to give an elongation and reduce the module of elasticity. The temperature of the warps can raised by a heating or scalding stage or by calendering. A transfer paper can be applied to the warps for a colored pattern to be transferred from the paper to the heated warps, and the paper is detached at the same speed as the warp forward movement, leaving the transferred pattern only on the heated warp level (34). The colored pattern is in parallel bands along the line where the paper is peeled away, where the colored bands are lined up near the warps which carry the transfer. An Independent claim is included for a woven fabric where the warps are crepe yarns. Preferred Features: The fabric is woven with a number of different weft yarns. The woven fabric has a pattern of parallel bands, where a part of each band has a higher color intensity than the remainder of the band. At least one band is in two colors.
