摘要:
To perform a flame-resistant treatment on a precursor fiber strand by sending hot air to a heat treatment chamber (2) through a hot air blowing nozzle (4) in a direction parallel to a running direction of a precursor fiber strand (10). The hot air blowing from the hot air blowing nozzle (4) passes through a porous plate and a rectifying member that satisfy the following conditions (1) to (4), wherein the conditions are set as follows: (1) A/B ‰¥ 4.0; (2) 0.15 ‰¤ ± ‰¤ 0.35; (3) 0 ‰¤ B-d ‰¤ 20; and (4) 80% or more of an area of one opening of the porous plate when causing facing surfaces of the porous plate and the rectifying member to overlap each other is included in one opening of the rectifying member, A indicating a hot air passage distance (mm) of the rectifying member, B indicating a horizontal maximum distance (mm) of one opening of the rectifying member, ± indicating a rate of hole area of the porous plate, and d indicating an equivalent diameter (mm) of the porous plate. Accordingly, it is possible to provide a parallel stream type flame-resistant heat treatment furnace having exhibiting the uniform heat transfer performance throughout the inside of the heat treatment chamber by preventing the blockage of the nozzle caused by a silicone compound generated inside the heat treatment chamber even in the hot air blowing nozzle having a simple structure.
摘要:
The invention relates to a method for coating fibres and material to achieve particular properties such as water repellency, oil-repellency and/or self-cleaning. Said particular properties are achieved by means of a pre-treatment of the fibres or the material and a subsequent coating with prepolymers and nanoparticles. The prepolymers are partly substituted with hydrocarbon groups or with fluorocarbon groups. The nanoparticles themselves can have surfaces treated with hydrocarbons or fluorocarbons. The prepolymers are fixed and hardened by irradiation with light of a wavelength from UV to visible.
摘要:
An apparatus for sizing warp yarns (1) comprising an unwinding station (2) of the warps from a supply beam (3), an application assembly (13) of a sizing liquor onto the warp yarns including application cylinders (5) and guiding rollers (4, 12), a drier station including a horizontal drying oven (6), and a winding station (8) of the warps onto an outlet beam (9). The warp yarns (1) are advanced through the drying oven (6) along a straight path without any bearing means between the exit of the application assembly (13) and the exit (14) of the drying oven (6), and the drying oven (6) is equipped with a combined heating system including infrared ray radiator sources (X) and hot air blower sources (Y) operated simultaneously and in a combined fashion. Peculiar features are provided for enhancing treatment evenness and adhesion of the sizing material to the warp yarns.
摘要:
Ein Trockner (1) zum Trocknen von kontinuierlich geförderter Ware, beispielsweise zum Trocknen einer Fadenschar, besteht im wesentlichen aus einer ersten Trockneranordnung (2) und aus einer zweiten Trockneranordnung (3). Zwischen den Trockneranordnungen (2, 3) wird ein Durchgang (4) zum Durchführen der Ware (5) gebildet. Die erste Trockneranordnung (2) ist in bezug zur zweiten Trockneranordnung (3) bewegbar ausgebildet. In einer Stopplage (S) des Trockners (1) ist die erste Trockneranordnung (2) in bezug zur zweiten Trockneranordnung (3) derart angeordnet, dass der Querschnitt des Durchgangs (4) grösser ist als in einer Betriebslage (B).
摘要:
A plurality of coated strands (14) are conveyed through a drying oven (26). A plurality of nozzles (48) impinge the upper surface of the coated strand as it passes therethrough. Baffle plates (54) positioned below the strands redirect the gas stream such that, after the gas stream has passed through the strands, it is redirected so as to impinge on an opposite surface of the coated strand. The strand is supported by positioning it between an additional pair of nozzles (82) that are tilted towards each other such that an upwardly directed gas stream issuing from the first nozzle intersects an upwardly directed gas stream issuing from the second nozzle along a line which along with the strand, forms a generally vertical plane. The combined upwardly directed force from the gas streams lifts and supports the strand while the opposing lateral force from each gas stream on the strand tend to reduce and lateral movement and stabilize its relative position.
