The specific structure of the injection mold for manufacturing the intermediate layer in the step 5 is as follows: referring to fig. 6, the injection molding die comprises an injection molding upper die 4 and an injection molding lower die 5 which are arranged oppositely from top to bottom, a cavity and a plurality of stand columns are arranged on the injection molding upper die 4, the stand columns 9 are of a structure narrowing from top to bottom, a through hole is formed after the cavity between every two adjacent stand columns is subjected to injection molding, an injection molding opening 6 is formed after the injection molding upper die 4 and the injection molding lower die 5 are matched, and a raw material for manufacturing a middle layer is injected into the injection molding upper die 4 and the injection molding lower die 5 from the injection molding opening 6, so that the middle layer.

The invention further provides a sports bra which is provided with the self-cooling sports mold cup.

The self-cooling sports mold cup provided by the invention has a physical ventilation cooling effect, can realize cooling and self-cooling, and the bra is more permeable, lighter and cooler, so that the problem of sultriness and airtight of the bra cup of the sports bra is solved, and the self-cooling sports mold cup has a more healthy and comfortable wearing experience.

Comparative experiment

In the sports bra provided by the invention, the mold cup comprises a first surface layer 1, an intermediate layer 3 and a second surface layer 2, the first surface layer 1 and the second surface layer 2 are both made of sandwich fabric, the intermediate layer 3 is made of sponge, a plurality of through holes are formed in the sponge, and each through hole 31 is of a structure which is narrowed from the first surface layer 1 to the second surface layer 2.

The sports bra comprises a mold cup and a mold, wherein the mold cup comprises a first surface layer, a middle layer and a second surface layer, the first surface layer and the second surface layer are made of sandwich fabrics, the middle layer is made of sponge, a plurality of through holes are formed in the sponge, and each through hole 31 is of a cylindrical structure with the same diameter.

The model sizes of the cups in the examples and comparative examples are identical, and the difference is only the shape of the through hole in the sponge.

Two-data comparison and result analysis

The test mode is as follows: the first is indoor test of warm-up dummy, using warm-up dummy and fan, respectively wearing the bras of the embodiment and the comparative example on two warm-up dummy, and taking the middle value after multiple tests. The warm-up dummy is an instrument for simulating heat and moisture exchange between human body and environment, has a size similar to that of a common adult, and consists of anatomical sections such as head, chest, back, abdomen, buttocks, upper posture, hands, lower posture, feet and the like. The warm-body dummy is a universal instrument and equipment for clothes thermal performance experiments. The temperature of the warm-up dummy is constant and is the same as the room temperature, and the body temperature of the warm-up dummy cannot be changed due to emotion change. The bra is worn on the warm-up dummy body. The fan that meets is placed in warm body dummy's outside, and it blows to warm body dummy's brassiere on, has the air to produce pressure differential from the brassiere middle through to produce refrigeration effect.

The second is a real outdoor sport experience test, the bras of the embodiment and the comparative example are worn on the body of a real person, and the sportsman jogges for 30 minutes on a jogging track, and the performance analysis results of the bras of the embodiment and the comparative example are as follows:

TABLE 1 Performance analysis results for the bras of this example versus the bras of the comparative examples

In the upper table, under the first kind of test condition, the temperature indicates the temperature between warm body dummy and the brassiere or warm body dummy chest epidermis temperature, and the temperature of the brassiere that this embodiment provided is obviously less than conventional brassiere in the comparative example, and the brassiere that this embodiment provided has physics ventilative cooling effect, can realize cooling from cooling. Under the second kind test condition, the wearing of the brassiere that this embodiment provided is more penetrating more light nice and cool, and the experience of wearing feels better.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
