TH3552B - Patterned fabric is caused by the density of composite fibers. - Google Patents

Abstract

Fabrics, which are not woven or knitted, consist of at least 15 percent composite fibers. Assembled with low melting point and the manufacturing process of such fabrics then consists of a bulging part next to the part where the fibers are. immediately massively by producing by pressing the fiber sheet under temperature below the melting point of the point element low melting within composite fibers and by applying sufficient heat and pressure to make the composite fibers transform. and is dense and cause the fibers in the fiber sheet to be densely located only in the patterned area

Claims (5)

1. A method for making a non-woven or knit fabric, in which there is a bulge and a separate layer from the extruded pattern section next to it. The fibers are fused. At least 15 percent of Such fibers are composite fibers with melting points. Low liquid and components with a high melting point. Into the channel between the pair of rollers with engraved pattern on the roller surface. This is lower than the softening point of the low melting point component in the composite fiber. Such a rolling so that the embossed roller part is pressed. Push it onto the fibers in the fiber panel as this panel is passed. To the channel between the rollers The method of this claim On controlling the temperature and pressure while the panel is loud Is passed through the channel between the rollers to make the fibers in The embossed surface area is pressed more denser and, at the very least, to the low melting point elements in the fibers. The assembly produces a cold flow and makes the fiber panel sound. It is more dense in the area of the embossed roller. In the meantime This method also maintains the next part of the fiber panel as an inflated section. And maintain the density in The panels by inflating and maintaining the density in the panels by creating a Permanent variation of composite fibers in sloped sections To maintain fiber Only in the slopes, stripes, in dense panels. 2. A cloth that is not a woven cloth or a knit cloth with a bulging part separated from the part. The pattern formed by the next compacting which is produced according to Method in claim 1 3. The method described in Proposition 1, where the fibers are composed With a round shell which is polyethylene and the core is a polyester. 4. Non-woven or knitted fabrics according to Proposition 2, whose fibers are composed of a polyethylene round shell and a core. Which is a polyester 5. Methods according to Claim 1, including the process of giving Heating the fiber powder with hot air at a high temperature only It is enough to melt fibers together and with other fibers. Before sending the panels through the channel between the rollers (5 claims, 1 page, 1 photo).
