Method for reducing cost of waterproof breathable clothes and improving breathing quality of waterproof non-breathable clothes

Abstract

A method of reducing cost of waterproof breathable clothes and improving breathing quality of waterproof non-breathable clothes uses more than two kinds of waterproof cloths with different water vapor permeability according to the physical characteristics of moisture, along with the structures of clothes themselves. The waterproof cloth with higher water vapor permeability is applied to parts of clothes most requiring heat dissipating and breathing (the place where moisture accumulates or generates), and the waterproof cloth with lower water vapor permeability or the waterproof non-breathable cloth is applied to parts of clothes less or not requiring heat dissipating and breathing. In other words, the proper moisture-permeable cloth is applied to each part of the clothes with respect to the requirement of heat dissipating and breathing. Therefore, the method can reduce the cost of the existing waterproof breathable clothes, and can improve the breathing quality of the existing waterproof non-breathable clothes.

1 . A method of reducing cost of waterproof breathable clothes and improving breathing quality of waterproof non-breathable clothes, wherein more than two kinds of waterproof cloths with different water vapor permeability are used and divided into several levels of permeability according to the magnitude of water vapor permeability of each cloth; each part of the clothes divided into the same number of levels as that of the cloths according to requirement of heat dissipating and breathing, and then the waterproof cloth with the level of permeability corresponding to the requirement of heat dissipating and breathing of the clothes applied to each part of the clothes;  
   
   
       2 . A method of reducing cost of waterproof breathable clothes and improving breathing quality of waterproof non-breathable clothes, wherein each part of the clothes is divided into more than two levels according to requirement of heat dissipating and breathing, and the same number of waterproof cloths of different water vapor permeability is used according to the number of levels for each part of the clothes; these cloths also divided into several levels of permeability according to the magnitude of water vapor permeability of each cloth, then the waterproof cloth with the level of permeability corresponding to the requirement of heat dissipating of and breathing of the clothes applied to each part of the clothes;  
   
   
       3 . The method of reducing cost of waterproof breathable clothes and improving breathing quality of waterproof non-breathable clothes according to  claim 1  and  claim 2 , wherein the waterproof cloth can include the waterproof non-breathable cloth having zero water vapor permeability.
