摘要:
Method of controlling the continuous convective heat treatment of a textile fabric web, which includes continuously remotely monitoring the temperature of a web being transported over a path in a given direction, directing heated air toward the web, and measuring the amount of heat given off to the web, which is proportional to the temperature of the web, as a function of the difference between the temperature of the air impinging on the web and the temperature of the air reflected by the web.
摘要:
Method of continuously applying a foamed treatment medium to a planar textile structure which includes applying the foam directly to a planar follower guidable synchronously into areal contact with the planar textile structure, and transfering the foam from the planar follower into the planar textile structure by applying vacuum, and apparatus for carrying out the method.
摘要:
Continuous method for uniform foam treatment of planar textile structures wherein a foamed treatment medium for finishing and/or dyeing is applied to the planar structure which is then subjected to underpressure, which includes sucking the foam onto the planar structure to which the foam is to be applied, and introducing the foam together with the planar structure into an underpressure chamber wherein the pressure is low compared to the internal pressure of the bubbles of the foam.
摘要:
Apparatus for continuously mechanically removing moisture from web-shaped porous material, includes a drum having a cylinder casing formed with holes therein, the drum being subjectible to negative pressure from within the cylinder casing, a cover layer of absorbent material formed with penetrating capillaries and uniformly disposed over the cylinder casing, means for guiding the web-shaped material about a part of the peripheral surface of the cylinder casing and the cover layer disposed thereon, whereby the moisture to be removed from the material is sucked through the holes and carried off with the aid of the negative pressure, an air-impermeable endless entrainer spaced from the cover layer and engageable with the web-shaped material guided about the part of the peripheral surface of the cylinder casing, for pressing the web-shaped material, in cooperation with the negative pressure from within the cylinder casing, against the cylinder casing covered by the cover layer of absorbent material.
