Embodiment 1
[0074] The hand model used in this embodiment is a hand model that can produce sweat and its water vapor discharge structure 2-1-2, and its basic structure is as follows image 3 As shown, the surface of the hand mold has a strip-shaped depression 1-3, the cross-section of the strip-shaped depression 1-3 is a semi-ellipse, the major diameter of the semi-ellipse is 0.58 mm, and the minor diameter is 0.46 mm. perpendicular to the film surface. The distribution of the strip-shaped depressions 1-3 on the surface of the hand mold, such as Figure 4 as shown, Figure 4 The right picture of is the front view of the hand model capable of producing sweat and its water vapor discharge structure 2-1-2, and the left picture is the rear view. Each finger is provided with 6 strip-shaped depressions 1-3, and a total of 30 strip-shaped depressions 1-3 are provided on the surface of the hand mold, and each strip-shaped depression 1-3 extends to the wrist of the hand mold. The strip-shaped d...

Embodiment 3
[0099] Adopt the preparation method comprising the following steps to prepare disposable nitrile gloves of the present invention:
[0100] Step 2) to step 9) are identical with embodiment 1;
[0101] Step 1) preparation generates the dipping nitrile latex of inner film 2-1: take by weight 100 parts of nitrile rubber emulsion respectively, 0.8 part of potassium hydroxide, 0.008 part of Tween 80 (surfactant), positive 0.083 part of heptanol (defoamer), 1.0 part of zinc oxide, 0.38 part of sulfur, 2.9 parts of titanium dioxide, 0.07 part of zinc diethyldithiocarbamate (vulcanization accelerator), 0.008 part by weight of polylysine, polylysine Amino acid is composed of 10-13 lysine residues, 0.003 parts by weight of dihydroxyphenylalanine, and 260 parts of water. After mixing, stir clockwise for 46 minutes at a stirring speed of 116 rpm, and grind 3 times with a paint grinder. The pH value of the obtained latex was 7.1-7.6.
