Abstract
The a barrier material, a barrier apparatus and a method for making the barrier material. In one respect, a double knit barrier material including pockets in which barrier supports may be inserted to create a barrier apparatus. The barrier material provides for a barrier which can be easily constructed in a short period of time by providing for a quick, easy, and uncomplicated way to secure the barrier material to the barrier supports by simply inserting barrier supports into pockets in the barrier material.
Claims21
A barrier material comprising:
- (a) a first ply of single-knit fabric;
- (b) a second ply of single-knit fabric;
- (i) said first ply of single-knit fabric and said second ply of single-knit fabric being joined together to form a double-knit fabric extension;
- (A) said double-knit fabric extension having:
- (1) a first edge along a length of the double-knit extension and an opposite second edge along the length of the double-knit extension.
- (2) at least a first and a second bounded area along the double-knit extension;
- (3) a first integral pocket formed between said first and said second bounded areas, the first integral pocket having a first pocket side and an opposing second pocket side extending between said first edge and said second edge;
- (a) said first pocket side comprising said first ply of single-knit fabric;
- (b) said second pocket side comprising said second ply of single-knit fabric;
- and
- (4) said first pocket side being selectively separable from said second pocket side to define a first interior area of the first integral pocket therein.

- (c) a plurality of barrier supports, including at least a first support and a second support;
- (i) said first support being positioned within said first integral pocket;
- and
- (ii) said second support being positioned within said second integral pocket.

A method of making a barrier material having at least one integral pocket therein, the method comprising:
- (a) producing a first ply of a single-knit fabric;
- (b) producing a second ply of a single-knit fabric;
- (c) binding the first ply aid the second ply of single-knit fabric to produce a first bounded region of double-knit fabric having a first selvage edge and a second selvage edge;
- (d) binding the first ply and the second ply of single-knit fabric to produce a second bounded region of double-knit fabric having a first selvage edge and a second selvage edge;
- (e) providing a non-bounded area between the first bounded region and the second bounded region;
- (f) separating the double-knit fabric between the first bounded region and the second bounded region into two plies of single-knit fabric to form the integral pocket at the non-bounded area of the double-knit fabric, wherein the integral pocket extends from the first selvage edge toward the second selvage edge of the fabric.
