DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The object of the invention, which relates to the technical aspects of textile dyeing and finishing, is the production of a so-called "piled" fabric.
Piled fabric, as is well-known to persons skilled in the art, is the result of knitting 100% polyester multifilaments on a warp-knitting machine. Several counts and filament quantities can be used; 160 decitex, 96 filaments are the most common.
The knitted fabric is disperse-dyed using conventional methods for dyeing 100% polyester. The resulting fabric has a plush-loop and a smooth side.
SUMMARY OF THE INVENTION
The present invention is a method of finishing various piled fabrics most notably piled fabrics with a napped, furry, lambskin or fleeced appearance. The invention discloses methods of making self-shaded, clouded or printed fabrics for each of these appearances.
First, to produce a finished piled fabric with a single napped side and a self-shaded appearance, direction of and against the pile using a napper to pull the backing meshes. to compact the backing.
When a piled fabric with two napped sides and a self-shaded appearance is required, direction of and against the pile using a napper to pull the backing meshes. to compact the backing. raising operation in the direction of and against the pile using a napper to pull the backing meshes. napper to compact the backing.
Between 10 and 50% black yarn is added to the multifilament to produce a fabric with a clouded appearance.
To produce a finished fabric with a printed appearance, the fabric is laundered first and subsequently printed on the plush-loop side.
To produce a finished fabric with a furry appearance, it is first treated as if a napped fabric were required with a pile-bursting treatment to elongate the backing meshes, after which the fabric is plushed and shorn.
To produce a finished fabric with a lambskin appearance, it is first treated as if a napped fabric were required, after which it is washed for roughly 20 minutes at approximately 40.degree. C. and roughly 30 minutes at approximately 120.degree. C.
A fleece-type appearance is produced by subjecting the sides of the fabric to a bursting operation to elongate the backing meshes, after which the fabric is plushed and washed for roughly 20 minutes at approximately 40.degree. C. and for roughly 30 minutes at approximately 120.degree. C.
BRIEF DESCRIPTION OF THE DRAWINGS
In order that the invention may be more readily understood, the following description makes reference to the accompanying drawings:
FIG. 1 is a diagrammatic representation of the raising principle used to produce a napped appearance on one side of the piled fabric.
FIGS. 2, 3, 4 and 5 are enlarged diagrammatic representations of the fabric in its various processing stages.
FIG. 6 corresponds to FIG. 1, showing how a double-side napped fabric is produced.
FIG. 7 is a diagrammatic representation showing the raising principle used to produce a pile fabric with a furry appearance.
The following description will be more easily understood when it is remembered that pile fabric is first produced on a warp-knitting machine using 100% polyester multifilaments. The knitted fabric is disperse-dyed on appropriate machines using widely known methods for dyeing 100% polyester yarn.
As is shown in FIG. 1, a napped appearance on one side of the piled fabric is produced by subjecting the fabric to 4 finishing operations on different machines, 2 raising operations on "carding" machine (1) and 2 felting operations on "felting" machine (2).
During the first two treatments on machine (1) the filaments are pulled and burst. FIG. 2 shows the fabric before plushed side (T1) is run through the machine, while FIG. 3 shows the same fabric after it has been run through machine (1).
The remaining two operations on machine (2) compact the pile backing and mingle the filaments to produce an appearance of greater density (FIGS. 4 and 5). The microscopic filaments having been burst and mingled, the resulting appearance is one of perfect uniformity and smoothness.
