Detailed Description

According to the above structural features of the present application, the embodiments of the present application will be further explained:

referring to fig. 1, the present embodiment provides a brassiere with a polyurethane PU foam mold cup assembly, which includes a cup 1, a heart 2, a shoulder strap 3, a rear portion 4 and a hook ring 5; the two cups 1 which are symmetrical left and right are fixedly connected through a chicken heart 2; the outer sides of the two cups 1 are respectively connected with the two back ratios 4 through sewing; the tail end of the rear part 4 is fixedly connected with the hook ring 5; two ends of the shoulder straps 3 are respectively fixedly connected with the bra cups 1 and the rear portion 4; a mold cup 11 is arranged in the cup 1, and the mold cup 11 is of a porous structure; a plurality of air holes 111 are formed in the mold cup 11; the outer surface of the mold cup 11 is provided with a groove.

The mold cup 11 with the porous structure is made of polyurethane, and the polyurethane has excellent performances of wear resistance, temperature resistance, sealing, sound insulation, good processability, degradability and the like.

The aperture of the porous structure of the mold cup 11 is 0.1 mm-0.3 mm. The aperture of the mold cup is a pair of physical contradictions, the thermal insulation performance is reduced due to the overlarge aperture, and the air permeability is reduced due to the undersize aperture, so that a compromise method is adopted, a small and small intermediate value is taken as a break-over point, the requirements of both parties are considered, and the contradiction is avoided.

The density of the mold cup 11 is 0.095-0.105/cubic centimeter, and the smaller density can realize lighter weight and reduce the oppression on a human body.

The air holes 111 are distributed in a rectangular linear lattice manner; the inner wall of the air hole 111 is spiral. The air holes 111 on the spiral inner wall can play a role in slowing down the air flow rate, so that a heat preservation effect can be achieved; and the diffusion of moisture can be performed in a low flow rate state, so that the ventilation holes 111 of the spiral inner wall still maintain the ventilation effect. Two ends of the air hole 111 are respectively communicated with the inner surface and the outer surface of the mold cup 11; the aperture of the air holes 111 is 0.3-0.5 mm.

The groove is in a Fermat spiral shape; the width of the groove is 0.3-0.5 mm, and the edge line density of the Fermat spiral is greater than the density of the central line, so that ventilation and heat dissipation of sweat glands on the periphery of the breast are facilitated.

The air holes 111 are not communicated with the grooves. After the air holes 111 are communicated with the grooves, the heat preservation performance is reduced linearly.

The outer edge of the mold cup 11 is provided with an embossing structure for avoiding the condition that the washing causes the loose abrasion of the outer edge of the mold cup 11.

Cup 1 is cotton cloth, compares in chemical fiber, and cotton cloth can reduce the stimulation to human body surface, improves the security performance.

The hook ring 5 is a drag hook or a hook structure.

The innovative principle is as follows: (1) the polyurethane material and the mold cup with the porous structure have excellent performances of wear resistance, temperature resistance, sealing, sound insulation, good processing performance, degradability, easy resilience and the like, and the defect of easy washing variability of the traditional sponge mold cup 11 is overcome. (2) The air holes 111 and the grooves are used alternately, and the grooves can reduce the local thickness of the mold cup 11, so that the invention principle of local quality is adopted, namely, a certain spiral area (the positions of the air holes 111 and the grooves) has better air permeability and poorer heat preservation, and the other part of spiral area (the positions of the non-air holes 111 and the non-grooves) has poorer air permeability and better heat preservation, so that the mold cup 11 (or the bra) integrally considers certain air permeability and certain heat preservation at the same time in a macroscopic angle, and the defect of poor air permeability of the traditional sponge mold cup 11 is avoided.
