Abstract

A base sheet, sandwiched between two piles of filaments, is anchored to one pile by drawing loops of filaments from that pile through the sheet and knotting or interlinking them directly at the sheet surface, loops of filaments from the other pile being drawn through the sheet and the first pile for knotting or interlinking along the surface of the latter pile.

Hampton Hunter Attorney- Karl F. Ross ABSTRACT: A base sheet, sandwiched between two piles of filaments. is anchored to one pile by drawing loops of filaments from that pile through the sheet and knotting or inter linking them directly at the sheet surface, loops of filaments from the other pile being drawn through the sheet and the first pile for knotting or interlinking along the surface of the latter pile.
FLUFFY TEXTILE WEB Our present invention relates to a fluffy textile web, of the type known as pile fleece, in which a nap of filamentary material is secured to a sheet of fabric or other substrate.
The general object of this invention is to provide a textile web of this description having a nap of loosely aggregated filaments of large volume on both sides of a central fabric or other sheet serving as a support and reinforcement therefor.
A more particular object is to provide a web structure of this description which does not require the use of separate threads to hold the two filamentary layers onto the base sheet.
In accordance with this invention, we provide a first pile of filaments on one side and a second pile of filaments on the other side, some of the filaments of the first pile being drawn in loop form through the sheet and anchored at the other side thereof in direct contact with that sheet; some of the filaments of the second pile are also drawn in loop form through the sheet as well as through the first pile and are anchored along the surface of the latter. The anchoring of the loops may be done by knotting and/or by chain stitching, eg as shown in U.S. Pat. No. 3,442,101.
Advantageously, the loops drawn through the base sheet from either side are arrayed in parallel rows running, preferably, in longitudinal direction of the generally rectangular web. These rows form pleats in the corresponding naps and allow a certain separation of the filamentary material from the sheet surfaces in the intervening zones. A large volume of air is therefore entrapped between the rows of loops so that the web, aside from being soft and fluffy, also acts as an effective heat insulator. Such webs are thus eminently suitable for use in comforters, linings, filter masses and the like, replacing the relatively expensive quilts, felts etc. conventionally used for such purposes.
The filaments may be natural or synthetic fibers and may include metallic (e.g. steel) threads admixed therewith for the sake of greater strength and/or electrical conductivity (antistatic).
The invention will be described in greater detail with reference to the accompanying drawing in which:
FIG. I is a rear view of a web according to the invention in an intermediate stage of manufacture;
FIG. 2 is a front view of the same web in a final stage of manufacture;
FIG. 3 is a longitudinal sectional view taken on the line Ill- [ll of FIG. 2; and
FIG. 4 is a cross-sectional view taken on the line lVlV of FIG. 2.
In FIG. 1 of the drawing we have shown the rear surface of a base sheet I which may be a fabric (as illustrated), a plastic foil or the like. A pile of filaments 2 (FIGS. 24) on the opposite side of the sheet I has some of its fibers drawn, e.g. with the aid of conventional latch needles, through interstices of the fabric 1 to form rows of chain stitches 3 anchoring this pile to the fabric. Another pile 4, placed against the rear surface of sheet 1 after the formation of the chain stitches 3, has its filament drawn in loops through the fabric and through the pile 2 to form rows of chain stitches 5 on the exposed surface of the latter pile. It will be noted that the two naps 2 and 4 are pleated between the rows of chain stitches 3 and 5 to form air pockets 6 and 7 extending longitudinally of the web.
The naps of the finished web can be teased, dressed, trimmed, ironed or otherwise treated by conventional equipment. The resultant product has a plush-type surface interrupted at its front side 2 by the visible chain stitches 5.
The two filamentary layers 2 and 4 may differ from each other in color, composition, depth, loop spacing and/or the manner in which the loops are tied, i.e. by chain stitches or by individual knots.
We claim:
1. A fluffy textile web comprising a base sheet; a first pile of filaments covering one side of said sheet and having some filaments thereof drawn in loop form through said sheet and anchored at the other side in direct contact with said sheet;
and a second pile of filaments covering said other side of said sheet and having some filaments thereof drawn in loop form through said sheet and said first pile, the last-mentioned filaments being anchored along the surface of said first pile.
2. A web as defined in claim 1 wherein the filaments of said first pile drawn through said sheet are arrayed in a first set of parallel rows, the filaments of said second pile drawn through said sheet being arrayed in a second set of parallel rows offset from the rows of said first set.
3. A web as defined in claim 2 wherein said sheet is generally rectangular, said rows extending lengthwise of the sheet.
4. A web as defined in claim 2 wherein the filaments of each row are interlinked by chain stitching.
5. A web as defined in claim I wherein the filaments of at least one of said piles include metallic fibers.

Claims (5)

A fluffy textile web comprising a base sheet; a first pile of filaments covering one side of said sheet and having some filaments thereof drawn in loop form through said sheet and anchored at the other side in direct contact with said sheet; and a second pile of filaments covering said other side of said sheet and having some filaments thereof drawn in loop form through said sheet and said first pile, the last-mentioned filaments being anchored along the surface of said first pile.
2. A web as defined in claim 1 wherein the filaments of said first pile drawn through said sheet are arrayed in a first set of parallel rows, the filaments of said second pile drawn through said sheet being arrayed in a second set of parallel rows offset from the rows of said first set.
3. A web as defined in claim 2 wherein said sheet is generally rectangular, said rows extending lengthwise of the sheet.
4. A web as defined in claim 2 wherein the filaments of each row are interlinked by chain stitching.
5. A web as defined in claim 1 wherein the filaments of at least one of said piles include metallic fibers.
