For convenience of explanation, the tearing strength, density, elasticity and air permeability of the foam silica gel bra mold cup of the invention are compared with those of the prior bra mold cup for detection. The test method collects the existing bra mold cup (hereinafter referred to as a sample), and the test results of the tear strength, the density, the elasticity and the air permeability are shown in the following table 1, table 2 and table 3:

example 2 various performance parameters of the foam silicone bra mold cup and sample are compared as in table 1 below:

name of detected article	Tear Strength (Kn/m)	Density (g/m)3)	Elasticity (Pa)	Air permeability (cfm)
					Sample (I)	46	0.8	2.14	155
Inventive product (inner cup layer)	51	0.2	2.25	160
					Products of the invention (outer cup layer)	48	0.9	2.4	245

TABLE 1

Example 3 various performance parameters of the foamed silicone brassiere mold cups and the samples are compared as follows in table 1:

name of detected article	Tear Strength (Kn/m)	Density (g/m)3)	Elasticity (Pa)	Air permeability (cfm)
					Sample (I)	46	0.8	2.14	155
Products of the invention	54	0.25	2.27	164
					Products of the invention (outer cup layer)	51	0.7	2.35	238

TABLE 2

Example 4 various performance parameters of the foamed silicone brassiere mold cups and the samples are compared as follows in table 1:

name of detected article	Tear Strength (Kn/m)	Density (g/m)3)	Elasticity (Pa)	Air permeability (cfm)
					Sample (I)	46	0.8	2.14	155
Products of the invention	55	0.3	2.28	168
					Products of the invention (outer cup layer)	53	0.6	2.3	215

TABLE 3

The tearing strength, density, elasticity and air permeability of the foam silica gel bra mold cup of the invention are all superior to the sample, which fully shows that the air permeability and the shaping effect of the foam silica gel bra mold cup of the invention are all superior to the sample. Meanwhile, the detection result also shows that the density of the inner cup layer 2 is the highest in the component parts by weight used in the example 2, which fully indicates that the density of the inner cup layer 2 is related to the component parts by weight of the component B, and the air permeability of the outer cup layer 1 is the best in the component parts by weight used in the example.

The invention improves the air permeability of the whole mold cup well by adjusting the weight parts of the components of the outer cup layer 1 and the plurality of diamond-shaped air holes 5 arranged on the outer cup layer 1; meanwhile, the shaping effect of the whole mold cup is well improved by adjusting the weight parts of the components of the inner cup layer 2, the peak head groove 202 and the arc-shaped bulge which are arranged on the inner cup layer 2, and the magnet 4 and the magnet sheet 3 which are embedded in the inner cup layer 2, so that the defects of poor ventilation and shaping effects of the existing mold cup can be well overcome.

As described above, the present invention can be preferably realized.
