Abstract

A process for making insulating fabric that includes mechanically orienting wool fibers into a batting capable of being used for insulation, and tacking the batting to a scrim with a loom via needles coupled to a needle board of the loom. Each of the needles includes a body having a pointed end and barbed edges, thereby enabling engagement with the batting when stroking in a first direction, and substantial disengagement with the batting when stroking in a second direction, wherein the tacking is performed primarily without the use of an adhesive.

Claims (14)

1 . A process for making insulating fabric, comprising:

mechanically orienting wool fibers into a batting capable of being used for insulation; and

tacking said batting to a scrim with a loom via needles coupled to a needle board of said loom,

wherein said needles each comprise a body having a pointed end and barbed edges, thereby enabling engagement with said batting when stroking in a first direction, and substantial disengagement with said batting when stroking in a second direction, and

wherein said tacking is performed primarily without the use of an adhesive.

2 . The process of claim 1 , wherein said wool fibers are one of a Merino or Alpaca superwashed wool fibers.

3 . The process of claim 1 , wherein a loom punch speed is one from a range of 200 to 400 strokes per minute.

4 . The process of claim 1 , wherein a needle penetration per square inch (NPPSI) of said loom is one from a range of 200 to 450.

5 . The process of claim 1 , wherein a needle density of said needle board is one from a range of 75 to 115 needles per linear board inch.

6 . The process of claim 1 , wherein said production width of said loom is a multiple of 30, 45, 36, or 72 inches, wherein a maximum production width is 160 inches.

7 . The process of claim 1 , wherein a scrim weight is one from a range of 8 to 34 grams per square meter.

8 . The process of claim 1 , wherein a loom speed is one of a range of 12 to 30 feet per minute.

9 . The process of claim 1 , wherein a batting weight is one of a range from 70 to 300 grams per square meter.

10 . The process of claim 1 , wherein a loom punch speed is approximately 400 strokes per minute, an NPPSI is one of a range from 350 to 450, said scrim is a weight of approximately 17 grams per square meter, and a loom speed is approximately 25 feet per minute.
