Benefits of technology

[0010] The present invention is directed to a knitted stretch spacer material including the use of an elastomeric material such as SPANDEX for stretch and compression resistance without increasing weight, and improved conformability and/or drape. The present invention is further directed to a knitted spacer material further processed for particular applications, for example including mold-based forming and heat setting to provide a fabric having raised, shaped dimples or domes existing in a predetermined, repeated pattern wherein the domes protrude significantly above the fabric surface to provide a three-dimensional (3-D) channel...

example 1

[0058] In this preferred embodiment of the knitted spacer material as shown in FIG. 12 and having a knitting pattern shown in FIG. 14, the material was formed using the following components:

[0059] In the first yarn system direction, a Polyester yarn type of 40 denier was used in combination with a 40 denier spandex yarn; in the second yarn system, a Polyester yarn type of 40 denier was used in combination with a 40 denier spandex yarn; in the third yarn system, a Polyester yarn type of 177 denier monofilament was used in combination with a 70 denier polyester yarn. The machine set up included the following parameters: A double knit machine with a dial height variance up to 250 thousands separation from the cylinder, utilizing spandex feeder to plait spandex on the dial only and cylinder only feeds. Requirements include facilities to implement monofilament yarn into the knitting elements with controlled measurement of amount to minimize tension and improve knitting of monofilament y...

Abstract

A fabric having a face surface and a back surface forming a fabric plane, wherein the fabric is further processed to produce spaced apart, repeated patterned domes extending out of the fabric plane, the domes forming channels therebetween, producing a molded formed 3-D fabric for evaporative cooling and/or insulation as well as comfort, stretch, compression resistance, decreased weight, and improved drape, softness, and/or conformability, depending upon the yarn component and fabric properties.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS(S) [0001] This non-provisional utility patent application claims the benefit of one or more prior filed applications; the present application claims priority from U.S. provisional application Ser. No. 60 / 655,617 which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION [0002] (1) Field of the Invention [0003] The present invention relates generally to textile products and, more particularly, to a 3-D fabric with domed shaped formed from a base “sandwich” material for providing cooling and / or insulation and improved stretch, compression resistance, decreased weight, and conformability and / or drape. [0004] (2) Description of the Prior Art [0005] U.S. Pat. No. 5,413,837 issued May 9, 1995 to Rock, et al. for Three-dimensional knit fabric teaches a three-dimensional knit or woven fabric that is permeable to water vapor but impermeable to liquid water is provided, including a first fabric layer, a second fabric layer and...
