Problems solved by technology

[0009] However, one of the continuing problems associated with body coverings such as outerwear, clothing, shoes, helmets and other garments or appliances, accessories, backpacks, etc. is to provide means and methods to overcome moisture generated due to heat, i.e., in Condesend water and trapped air collected within the microenvironment created by the enumerated body coverings
These problems all cause discomfort and act as breeding grounds for bacteria and various physical ailments

Embodiment 1

[0112] Prepare the aqueous phase by mixing in the following order of addition:

[0113] Pluronic (BASF) F88 .3% solution 93.36%

[0114] Foley Fluff (Buckeye Cellulose) 1.54

[0115] Glycerin (Emery 916) 3.07

[0116] Pluronic (BASF) L62 1.29

[0117] Superabsorbent (Stockhausen AP 80-HS) 0.10

[0118] Guar Gum (Alpha-Chem) 0.64

[0119] The aqueous phase was then added to and mixed with 33 wt% Dow Chemical Hypol Prepolymer. The mixed composition was cast on a silicone release paper and covered with a second sheet of the same (release paper). The thickness of the resulting foam reaction was controlled by a spacer and top cover plate clamped to the bench. After about 8 minutes of emergence and curing, the foam composite was removed and dried in an oven. The foam assembly was then laminated to K2 fabric supplied by Hub Fabric using heat activated web adhesive from Bostic.

Embodiment 2

[0121] As in Example 1, an aqueous phase was prepared comprising:

[0122] Pluronic (BASF) F88 1% solution 37.88%

[0123] Calcium carbonate (Noah Technologies) 54.43

[0124] Glycerin (Emery 916) 7.59

[0125] Superabsorbent (Stockhausen AP 80-HS) 0.1

[0126] The aqueous phase was then added to and mixed with the above 27.5% Prepolymer. The mixture was poured between two spacers on release paper, as in Example 1, and 1 / 4 thickness of 2.5 (oz / yard 2 ) oz. / sq.yd. of polyester nonwoven fibers (obtained from Carr-Lee) were placed on the liquid mixture. Then add a piece of release paper, to the top of the rising foam nonwoven, bonded. In this example, the thickness of the spacer is 1 / 8 (obtained by pressing 1 / 4 thickness of nonwoven fibers), so as to correspond to the desired 1 / 8 thickness of the final composite material. The composite is shown in FIGS. 3 , 4 , 5 , 6 and 7 . It is well known to those skilled in the art that various cell sizes, hydrophilicity, water retenti...

Embodiment 3

[0133] To reduce the density of the foam composite described in Example 2, the formulation was changed to include:

[0134] Pluronic (BASF) F881% solution 89.11%

[0135] Sodium bicarbonate (Arm-Hammer) .90

[0136] Glycerin (Emery 916) 9.99

[0137]The aqueous phase was mixed with Dow Chemical Hypol in a 1:1 weight ratio. The mixed composition was cast on the leather surface, covered with release paper, and sized with spacers. After curing and drying, the fabric layers are thermally laminated with a web adhesive. This method is not used for the product shown in Figure 5, in that the covering fabric 9 is eliminated. This approach defines another embodiment which shows the versatility of the invention. The formulation change between Example 3 and Example 2 lowered the density of the foam from 15.61 lb. / cu.ft. (pounds per cubic foot) to 10.91 lb. / cu.ft., about 9%.
