Abstract:
In a method of heat fulling and water washing of cloth, hot fluid is injected onto both surfaces of the cloth from hot fluid injection nozzles in upper and lower rows to sandwich the cloth in such manner that the positions of nozzles in the upper row alternate with those nozzles in the lower row, with the cloth passing through an opening between upper and lower net conveyors so that the cloth is immersed in cleaning liquid, with both a cleansing effect and fulling effect being given to the cloth.
Abstract:
A method and apparatus for impregnation of a dry fabric is disclosed including a purging device which is provided immediately upstream of a supply of liquid within an impregnation tank. The purging device urges a condensable gas through the dry fabric immediately prior to entry of the fabric into the liquid with the purging device providing a pressure differential across the fabric. The fabric is preferably conveyed by a first endless conveyor belt through a passageway of the purging device and subsequently into the impregnating liquid and beneath a first squeeze roller. The purging device displaces the non-condensable gas or air within the fabric with a condensable gas preferably steam.
Abstract:
An apparatus for subjecting a continuous length of moving material to a fluid treatment. The material is initially soaked in a bath of processing fluid while in a substantially tensionless condition. Immediately thereafter, the material is guided through a treatment chamber where it is exposed to a high velocity flow of the same processing fluid.
Abstract:
The invention relates to a tank for washing a warp thread, provided with a device for intensifying the washing effect set in rotation inside the tank. Each device includes a body having cylindrical geometry, having circular cross section, which has comprises a plurality of longitudinal bars arranged along the cylindrical side surface of the device. Between each pair of adjacent bars a longitudinal slit is defined. The body also has a pair of end elements extending radially, forming the opposite bases of the body and configured to support and enclose the bars. The body also has a pair of opposite rotation pins, obtained on the respective outer surfaces of the end elements and that extend along an axial direction and parallel to the direction of extension of the bars. The body also has a tangential turbodynamic flow generator, arranged inside the body and configured to intensify the interchange between the washing liquid and the warp thread through the longitudinal slits during the rotation of the device.
