Abstract

The utility model provides a brassiere cup, including the sponge cloth, the upper surface of sponge cloth has first polyamide fibre spandex underclothes cloth through first environment-friendly polyurethane glue hydrothermal pressure, the lower surface of sponge cloth has second polyamide fibre spandex underclothes cloth through second environment-friendly polyurethane glue hydrothermal pressure, and its preparation method is: after a circular or oval cup body is formed by using a mold through injection pouring, two layers of nylon spandex underwear cloth are pasted, compared with the prior art that rectangular sponge cut into is adopted to press the cup body on a forming machine, and then the sponge outside the cup body is trimmed and treated as waste, the nylon spandex underwear cloth saves a large amount of sponge cloth, reduces more than 30% of sponge materials, and greatly reduces the production cost. In addition, the utility model does not need complex procedures and can keep the wearing comfort. The material of the cup body is selected, so that the material which generates harmful substances due to thermal degradation in the hot-press molding and shaping process is avoided.

Description

Bra cup

Technical Field

The utility model relates to a brassiere cup field, in particular to brassiere cup.

Background

The existing bra cup is formed by compounding a sponge sheet and cloth with glue, then pressing the mixture on a cloth cup mold by a hot-press forming machine, and heating at high temperature to make the sponge flow into a cup shape. The method has the advantage of high material loss during cup body production. The method forms a cup body on a rectangular sponge cloth, and the sponge outside the cup body is treated as waste material when the sponge outside the cup body is trimmed.

SUMMERY OF THE UTILITY MODEL

The other purpose of the utility model is to provide a bra cup obtained by the processing method.

A bra cup comprises a sponge cloth, wherein a first nylon spandex underclothes cloth is pressed on the upper surface of the sponge cloth through a first environment-friendly polyurethane adhesive water, and a second nylon spandex underclothes cloth is pressed on the lower surface of the sponge cloth through a second environment-friendly polyurethane adhesive water.

The beneficial effects of the utility model are that

The utility model can stick two layers of nylon spandex underwear cloth after the bra cup is molded out by adopting an injection pouring method, does not need complicated procedures and can keep the wearing comfort. The material of the cup body is selected, so that the material which generates harmful substances due to thermal degradation in the hot-press molding and shaping process is avoided.

fig. 3 is a schematic structural diagram of the nylon spandex underwear fabric of the utility model.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

as shown in fig. 1, a method for processing bra cups comprises the following process flows:

(1) firstly, molding 1/2 cups, 3/4 cups or full cups by using a mold and adopting an injection casting method;

(2) respectively spraying environment-friendly polyurethane glue on the upper surface and the lower surface of the cup body;

(3) after the upper surface and the lower surface of the cup body are sprayed with the environment-friendly polyurethane glue, the cup body is placed between two layers of nylon spandex underwear cloth, so that one layer of the nylon spandex underwear cloth is positioned on the lower surface of the cup body, the other layer of the nylon spandex underwear cloth is positioned on the upper surface of the cup body, and the two layers of the nylon spandex underwear cloth are respectively pressed on the upper surface of the cup body and the lower surface of the cup body through a hot press forming machine;

(4) trimming the redundant nylon spandex underwear cloth on the upper surface of the cup body and the lower surface of the cup body.

This practicality adopts the method shaping of injection pouring to go out the cup with the mould earlier after, pastes two-layer polyamide fibre spandex underclothes cloth, adopts the rectangular sponge that cuts into to press into the cup on the forming machine among the comparison prior art, carries out the deburring as waste material with the outer sponge of cup again and handles, this practicality has practiced thrift a large amount of sponge cloth, reduces more than 30% of sponge material, great reduction manufacturing cost.

The environment-friendly polyurethane glue is synthesized by taking polyester polyol, castor oil, isocyanate, a hydrophilic chain extender, organosilane, a salt forming agent, a solvent, a catalyst and deionized water as raw materials, wherein the weight ratio of a mixture of the polyester polyol and the castor oil to the isocyanate to the hydrophilic chain extender to the organosilane to the salt forming agent is (110-120) to (35-45) to (6-8) to (2-4) to (6-10), and the weight ratio of the polyester polyol to the castor oil is 100 to (10-20). The environment-friendly polyurethane glue has good bonding strength and good water resistance.

As shown in figure 3, the nylon spandex underwear fabric comprises the following components in percentage by mass: 28% of cotton 6, 22% of spandex 7 and 50% of chinlon 8, wherein the main component of the front side of the fabric is chinlon 8, the main component of the back side of the fabric is cotton 6, and the spandex 7 is clamped between the front side and the back side. The chinlon spandex underwear fabric has stable structure, good elasticity, fine and soft front surface, smooth hand feeling, elegance and beauty, and has the body shaping and beautifying functions; the back surface of the fabric is thick and solid, the hand feeling is rough, the appearance is rough, the fabric has good moisture absorption and air permeability and heat retention, and the functionality and the physiology are unified.

As shown in fig. 2, a bra cup comprises a sponge cloth 1, wherein the upper surface of the sponge cloth 1 is hot-pressed with a first nylon spandex underwear cloth 4 through a first environment-friendly polyurethane glue 2, and the lower surface of the sponge cloth 1 is hot-pressed with a second nylon spandex underwear cloth 5 through a second environment-friendly polyurethane glue 3.

The above description is not intended to limit the technical scope of the present invention, and any modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention still fall within the technical scope of the present invention.

Claims

1. A brassiere cup, its characterized in that: the underwear comprises sponge cloth, wherein a first nylon spandex underwear cloth is hydrothermally pressed on the upper surface of the sponge cloth through a first environment-friendly polyurethane adhesive, and a second nylon spandex underwear cloth is hydrothermally pressed on the lower surface of the sponge cloth through a second environment-friendly polyurethane adhesive.
