TH18853A - A method for producing a nonwoven fabric-like thermoplastic film. - Google Patents

Abstract

To make the surface of the thermoplastic film form a non-woven fabric-like pattern, arrange for a mold with a non-woven layer consisting of The metal fiber fibers are interwoven without Orderly and keep the surface of the thermoplastic film Softened heat Form a straight pattern on the surface of a non-woven layer by vacuum suction, by a vacuum pump, or by force from a squeezing roller.

Claims (4)

1. A method for surface treatment of thermoplastic films with an imitated non-woven form. Appearance of the fabric It is defined by a large number of strands which randomly move through a series of cylindrical-shaped, non-woven layers formed by a mixture of Thermoplastic fiber Which is mixed with fibers A metal of a non-woven layer that mimics the character of the fabric Patterned using fibers Fibrous metal Weaving around in a mess And allow air to flow in the direction of Thick layer of non-woven The layer through which the air passes is shaped along at least part of the surface of the ball. Cylindrical rolling To support the aforementioned non-woven layer on the bottom of the non-woven layer And a suction device, which is placed Inside the said roller To have a vacuum effect through the layer that air can pass through And on the non-woven layer from above Descend to the bottom of the non-woven layer (A) contact with the surface of the non-woven layer of the heat-softened film, and (b) the thermoplastic film molding. Which is thermally softened, coupled with the aforementioned non-woven layer under the action of vacuum fed through the air layer. It is passed directly to the surface of the thermoplastic film that has been thermally softened. Into contact with the aforementioned non-woven layer To make a pattern consistent with the pattern that occurs on top of the non-woven layer, where during the printing process (b) the thermoplastic film is also softened. The heat is supported by the curved boundary of the non-woven layer. And the extent of the curvature of the roller Such a cylinder Which is placed under the aforementioned non-woven layers and forms the air-permeable layer 2.Methods for surface treatment of thermoplastic films with a slotted non-woven pattern. Appearance of the fabric That is defined by a large number of fibrous fibers, which passively Methodology using a printed set consisting of a cylindrical-shaped, non-woven layer that mimics the appearance of the fabric. That is formed using strands of metal fibers Interweaving in a chaotic manner, the non-woven layer is separated from And placed on the underside of the shelf that has been formed Along at least part of the surface of the cylindrical roller. To accommodate the non-woven layer on the The bottom of the non-woven shelf and the squeezing device located near the top of the non-woven step. To compress and compress the discs Such thermoplastic film Attach the non-woven layer, which consists of the following steps: (a) the heat-softened film touches the surface of the non-woven layer, and (b) the poured film. Thermoplastic, which is thermally softened Together with the aforementioned non-woven layer Under the action of the compression effect of the compression device Articulate with film Thermoplastic, which is thermally softened Therefore, resistance on top of the non-woven layer creates a pattern corresponding to the pattern that occurs on top of the non-woven layer. Where, during the (b) printing process, the thermoplastic film is also softened The heat is supported by the curved boundary of the non-woven layer. And the extent of the curvature of the roller Such a cylinder Which is placed under the aforementioned non-woven shelf and constitutes the support shelf. 3. Method according to Clause 2, where the printing process takes place by using a thermo film. The thermally softened plastic is in contact with the non-woven layer. Which takes shape from the ingredients Of thermoplastic fibers Which was mixed as fused with the metal fibers of the non-woven step 4. Method for surface treatment of thermoplastic film according to Clause 1 or Clause 2 where thermoplastic fibers less than 50% by weight are mixed with the metal fibers of the layer. Like such non-woven fabric
