ABSTRACT:

FIELD OF THE INVENTION
The present invention relates generally to a laminated cloth, and more particularly to a laminated cloth that is breathable and compressible.
BACKGROUND OF THE INVENTION
The compressible laminated cloth of the prior art is composed of a thin sheet of knitcloth and a thin sheet of a foam elastic material, which are pressed together. The foam elastic material is generally foam cotton, ethylene vinyl acetate (EVA), or neoprene. Such a prior art compressible laminated cloth as described above is used in making shoes, exercise devices, bags, etc. The foam cotton has an aging problem, whereas EVA and neoprene have a breathing problem.
There is another prior art laminated cloth, which is composed of two thin sheets of knitcloth and a fiber support layer sandwiched between the two parallel knitcloth sheets. This laminated cloth is soft and breathable; nevertheless its compressibility is poor in light of the limited number and length of the fiber in the fiber support layer. In addition, this laminated cloth is expensive.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a breathable and compressible laminated cloth which can be made at a low cost and is free from the problems of aging and hydrolysis.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by the breathable and compressible laminated cloth consisting of a first cloth sheet and a second cloth sheet. The first cloth sheet has a knitcloth layer and a hairy layer extending from one side of the knitcloth layer. The second cloth sheet is adhered to the hairy layer which is both breathable and compressible.
