摘要:
A method and apparatus is provided for controlling the distribution of color on a web of textile material in a textile dyeing process. The apparatus includes a color sensor for sensing a selected color characteristic of the textile web, such as, for example, the distribution of color, at a sensing location downstream of a nip device of a textile padding machine. The nip device removes excess dye liquor from the textile web to dispose the textile web at an initial moisture content as it exits the textile padding machine. The amount of the dye liquor removal through the nip operation is controlled in response to the color characteristic sensed by the color sensor so that the textile web is disposed at an initial moisture content upon exiting the textile padding machine which facilitates a desired color distribution when the textile web is subsequently dried.

The present invention provides a method and apparatus for monitoring the application of dye to a traveling web of textile material. The apparatus includes a color characteristic detecting assembly which is movable between an initial detecting position in which it detects a color characteristic of the textile material web shortly after the web has emerged from a dye liquor bath and a post-drying detecting position in which it detects a color characteristic of the textile material web after the web has been handled in a drying device. The post-drying detection of the textile material web enables the apparatus to detect an out-of-limits color characteristic situation which may not appear or be detectable until after the web has been subjected to the drying process. The color characteristic detecting assembly is connected to a control unit which controls the nip pressure of a pair of nip rollers which remove excess moisture from the textile material web.
摘要:
Applying non-treating liquid to a traveling textile fabric substrate during temporary change-over discontinuance of treating liquor application in a textile treating and drying range with the non-treating liquid being applied in an amount sufficient to approximate the amount of treating liquor applied during normal operation of the range so as to allow the dryer to continue operating at substantially normal operating temperatures without damage to the fabric substrate. A non-treating liquid applicator is shifted between an inoperative position out of the path of the textile fabric substrate into an operative position in engagement with the substrate. The applicator includes a roller for arcuate engagement with the substrate and to which liquid is applied by spray and is uniformly distributed by a squeeze roll acting on a cover on the roller of material capable of retaining and transferring liquid onto the substrate. Fabric guide plates are mounted adjacent to the roller and extend generally tangentially from the roller on opposite sides thereof under the traveling substrate to guide the substrate substantially flat and crease-free as it travels to and from the roller.
摘要:
A method of cleaning residual dye material from rollers of a textile fabric drying oven during passage of a travelling cloth lead therethrough. The method involves applying a cleaning material to the travelling cloth lead in advance of the oven and rotating the rollers to be cleaned at a surface speed different from the surface speed of the cloth lead to cause a cleaning action of the cloth lead against the rollers. The change in roller speed can be accomplished progressively, either by acceleration or deceleration and can be accomplished on the rollers individually or in sets.
摘要:
Applying evaporable finishing substances such as high-refinement media, dyes and optical brighteners, by evaporating the finishing substance and transferring to the textile material in the vapor phase via a line system. Smudging or smearing and re-evaporation of the vapor-deposited material in a continuously operating finishing system is avoided according to the invention by heating the textile material prior to the vapor deposition to a treatment temperature above the evaporation temperature and by using a finishing substance with a dew point in the finishing substance/transport mixture below the treatment temperature of the textile material.

Method of continuously treating planar textile structures by applying thereto a treatment medium in the form of foam, which includes subsequently applying underpressure to the planar textile structures at a magnitude at which the foam is completely destroyed without any appreciable flow through the material of the planar textile structures.
