Composite materials with membrane

Abstract

Composite materials are described herein. An example composite material may comprise a shell fiber layer. The example composite material may comprise a membrane disposed adjacent the shell fiber layer.

Description

BACKGROUND

Some items, such as snow pants, footwear, tents, etc., may be useful for keeping users comfortable. Keeping users comfortable may comprise keeping users dry from rain, hail, snow, etc. Making items out of material that is sufficiently water-resistant may keep users dry. Keeping users comfortable may comprise allowing hot air to escape so that users may remain cool. Making items out of material that is sufficiently breathable may allow hot air to escape. Improvements are needed.

DETAILED DESCRIPTION

Composite materials are described herein. The composite materials may be or comprise laminate materials having a plurality of layers. An example composite material may comprise a shell and a membrane. The shell may comprise a shell fiber layer. The shell may comprise various materials such as polymers. The shell may comprise polyester, nylon, recycled polyester, elastane, or combinations thereof. Other materials may be used. The membrane may be or comprise a breathable membrane. The membrane may be or comprise a water proof or water repellant membrane. The membrane may be formed from various process such as fiber spinning (e.g., electrospinning). Together, the shell and membrane may have a fabric weight. Various combinations of shell and membrane weight may be used. The membrane may have a weight of less than 9 gsm, less than 8 gsm, less than 7 gsm, less than 6 gsm, less than 5 gsm, less than 4 gsm, or less than 3 gsm. Other weight membranes may be used. The shell and the membrane may be disposed adjacent each other and may be coupled together, for example using adhesive.

The composites of the present disclosure show improved performance over comparative conventional materials. As shown more clearly in Tables 1-3, the composite materials of the present disclosure are identified using ID's: LV6W, LV6Z, LV74, LWEN, LV71, LWEQ, LV75, LWEP, LV7B, LV7D, and LWEO. The comparative examples are identified as A-L. The Appendix, which is hereby incorporate herein by reference in its entirety shows improved performance of the composite materials after 20 launderings.
