Embodiment 1

[0031] Embodiment 1: see Figure 1-3 , the improved bra steel ring of the present invention, the steel ring 1 is made of modified thermoplastic polyurethane elastomer after being injected into a mold, and the front and back sides of the steel ring 1 are correspondingly provided between one end and the other end. Relatively dense grooves 2, so that the inner and outer layers of the bra cup can be tightly embedded in the groove 2 after spraying glue, cold paste, and molding, so as to be connected and fixed with the steel ring 1; the groove 2 is a hole structure ; The steel ring 1 is an arc-shaped steel ring that can adapt to the shape of the human breast, and the length of the inner arc 3 near the inner side of the breast is 50-60% of the length of the outer arc 4 near the outer side of the breast; Both ends of the ring 1 are provided with flat extensions 5, and the length of the extensions 5 is 2-4% of the overall length of the steel ring 1; the modified thermoplastic polyureth...

Embodiment 2

[0036]Embodiment 2: the improved bra steel ring provided by this embodiment and its processing method, and the brassiere made of the improved bra steel ring, its overall technical scheme is basically the same as that of embodiment 1, the difference is that this embodiment provides The processing method of the improved bra steel ring, it comprises the steps:

[0037] (1) Preparation of modified thermoplastic polyurethane elastomer material: Add 48 parts of the measured copolyether into a four-neck flask, vacuumize and ventilate nitrogen, control the temperature at 100°C to remove moisture, add 33 parts of isocyanate and 3 parts of organotin, and Stir, pre-polymerize at 110°C for 1-2 hours, then add 16 parts of diol, 18 parts of urea-formaldehyde / silicon dioxide composite microspheres, and 5 parts of chitosan into the flask, continue to blow nitrogen under vacuum, and quickly stir for 1 After -2 hours, the solution becomes viscous, stop vacuuming and nitrogen, continue to react ...

Embodiment 3

[0039] Embodiment 3: the improved bra steel ring provided by this embodiment and its processing method, and the bra made of the improved bra steel ring, its overall technical scheme is basically the same as that of embodiment 1-2, the difference is that this embodiment The processing method of the improved bra rim provided by example, it comprises the steps:

[0040] (1) Preparation of modified thermoplastic polyurethane elastomer material: Add 50 parts of the measured copolyether into a four-neck flask, vacuumize nitrogen, control the temperature at 100°C to remove moisture, add 35 parts of isocyanate and 5 parts of organotin, and Stir, pre-polymerize at 110°C for 1-2 hours, then add 13 parts of diol, 20 parts of urea-formaldehyde / silicon dioxide composite microspheres, and 8 parts of chitosan into the flask, continue to blow nitrogen under vacuum, and quickly stir for 1 After -2 hours, the solution becomes viscous, stop vacuuming and nitrogen, continue to react for 3-5 minut...

Abstract

The invention relates to the technical field of underwear and in particular discloses a kind of improved bra underwires. The improved bra underwires are formed by injecting modified thermoplastic polyurethane elastomer into a mould and then carrying out integral moulding, and relatively dense grooves are accordingly formed in the front and back of the underwires from one end to the other end, so that an inner layer and an outer layer of a bra cup can be closely embedded into the grooves to be connected and fixed with the underwires after being sequentially subjected to glue spraying, cold laminating and mould pressing. The invention also discloses a processing method of the improved bra underwires and a bra product applying the underwires. The improved bra underwires disclosed by the invention is low in cost, a one-time moulding manufacturing process is adopted, environmental protection is realized, resource is greatly saved, and the grooves in the underwires are closely embedded with a bra body, so that the formed bra has good fixity and washing resistance, is difficult to deform, can replace expensive like products and has extremely high marketing value and good economic benefit.

Description

technical field [0001] The invention relates to the technical field of underwear, in particular to an improved bra steel ring, a processing method thereof, and a bra product with the steel ring. Background technique [0002] The function of the underwire in a bra is to provide support. The traditional underwire used for brassiere is basically a U-shaped metal wire. There are metal wires free and moving in the fabric cover, which will affect the supporting effect and aesthetics of the bra after the wire moves. In addition, the metal wire needs to be placed on the fabric In the sleeve, the processing cost is increased. Existing research reduces the risk of the steel ring piercing the fabric sleeve by placing the metal wire in the plastic shell to prevent the steel ring from piercing the fabric sleeve, or only placing the plastic material in the fabric sleeve. There are problems such as high cost. It is necessary to place the steel ring in the fabric sleeve first to prevent t...
