Abstract
A chamois-foam laminate sandwich structure is provided to increase the water absorbent properties by foam reservoir pockets and to provide for increased water delivery upon squeezing with substantially the same "hand" and feel as the original chamois.
Claims22
A chamois-foam sandwich composite comprising a pair of thin outer layers of real chamois skin laminated together with a thin, soft, flexible foam layer therebetween, the layers being adhesively bonded in a matrix of spaced points or regions, with the adhesive area embraced by the bonded regions occupying a minor portion of the surface area and bounding reservoir foam pockets.
A method of imbuing chamois-skin layers with water absorbency and without substantial change in "hand" and feel, that comprises, producing a pattern of spaced regions occupying a minor portion of the surface area of the layer along the inner surface of one or both of a pair of opposing thin layers of real chamois skin to which adhesive is applied, laminating the pair of thin chamois skin layers together with a thin, soft, flexible foam plastic layer therebetween, providing the foam layer with a pattern of openings aligned with said spaced regions, and compressing the chamois layers at said regions to adhere the same.
A method of imbuing chamois skin layers with water absorbency and without substantial change in "hand" and feel, that comprises, producing a pattern of spaced adhesive regions along the inner surfaces of a pair of opposing layers of real chamois skin, laminating the pair of thin chamois skin layers together with a thin, soft, flexible foam plastic layer therebetween and with the margins of the chamois layers extending beyond the foam layer, compressing the laminate at the said spaced regions and at the said margins to bond the same thereat, with intermediate regions comprising uncompressed foam reservoirs encased by said chamois layers and occupying the major portion of the laminate surface area.
A chamois-foam sandwich comprising a pair of thin outer water permeable layers, at least one of which is real chamois skin, laminated together with a thin, soft, flexible foam layer therebetween, at least portions of the chamois skin layer being compressed and adhesively bonded to the foam layer at spaced points in the sandwich as thus compressed.
