Problems solved by technology

But because of the three-dimensional fibrous structure of the standing cotton, its washing resistance is very poor, and it cannot completely replace the sponge. The sponge layer must be pressed on the surface of the standing cotton to ensure the washing resistance of the standing cotton

Embodiment 1

[0054] like figure 1 Shown is a kind of upright cotton washable bra coaster, including an inner upright cotton interlayer 1 and an outer upright cotton interlayer 2 that are sequentially fitted, and the inner upright cotton interlayer 1 and the outer upright cotton interlayer 2 are composed of at least two upright cotton layers 10, each upright cotton layer 10 is provided with a glue layer 3.

[0055] The total thickness of the inner upright cotton interlayer 1 is 3-5 mm, and the total thickness of the outer upright cotton interlayer 2 is 3-5 mm.

Embodiment 2

[0057] The difference between this embodiment and embodiment 1 is: as figure 2 As shown, a layer of upright cotton core layer 4 is arranged between the inner upright cotton interlayer 1 and the outer upright cotton interlayer 2 .

[0058] The maximum thickness of the upright cotton core layer 4 is 4-10mm, and the edge thickness of the upright cotton core layer 4 is 1-2mm.

[0059] like image 3 As shown, the thickness of the upright cotton core layer 4 gradually decreases from the middle to the surrounding.

[0060] The inner upright cotton interlayer 1 and the outer upright cotton interlayer 2 are provided with four upright cotton interlayers.

[0061] The thickness of each standing cotton interlayer is 0.5-1mm.

[0062] Other technical features of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Embodiment 3

[0064] The difference between this embodiment and embodiment 1 or embodiment 2 is that the glue in the glue layer 3 is mixed with the following raw materials in parts by weight:

[0065] Neoprene latex 10 parts

[0066] 5 parts n-butanol

[0067] 25 parts deionized water

[0068] 1 part emulsifier

[0069] Acrylic emulsion 5 parts

[0070] Butyl acrylate 1 part

[0071] Ethylene-vinyl acetate copolymer emulsion 10 parts

[0072] 3 parts hide glue

[0073] Polyurethane associative thickener 2 parts

[0074] 1 part calcium stearate

[0075] Propolis 15 parts

[0076] 9 parts of starch

[0077] 1 part silicone defoamer.

[0078] The mixing ratio of the neoprene latex, acrylic emulsion, and ethylene-vinyl acetate copolymer emulsion is 1:0.5:1.

Abstract

The invention relates to the technical field of bra underwear and particularly relates to a three-dimensional cotton water-washing-resisting bra cup pad and a preparation method thereof. The longitudinal cotton water-washing-resisting bra cup pad comprises an inner three-dimensional cotton interlayer and an outer three-dimensional cotton interlayer, which are fitted in sequence, wherein each of the inner three-dimensional cotton interlayer and the outer three-dimensional cotton interlayer is composed of at least two layers of three-dimensional cotton layers; and a glue layer is arranged between each two three-dimensional cotton layers. The preparation method comprises the following steps: step 1: coating the surface of one piece of three-dimensional cotton with glue; carrying out hot press fitting to obtain a planar material with the inner three-dimensional cotton interlayer and the outer three-dimensional cotton interlayer; step 2: taking the inner three-dimensional cotton interlayer and carrying out pre-die-pressing by utilizing die pressing equipment; step 3: covering the surface of the inner three-dimensional cotton interlayer subjected to the pre-die-pressing with the outer three-dimensional cotton, and carrying out die pressing and forming by utilizing a pressing die; and step 4: cooling, carrying out pressing fitting, and shaping a cup prototype obtained by the die pressing in the step 3, and cutting to obtain the three-dimensional cotton water-washing-resisting bra cup. The three-dimensional cotton water-washing-resisting bra cup is wholly made of the three-dimensional cotton material so that the three-dimensional cotton water-washing-resisting bra cup pad has the advantages of good air permeability, excellent antibacterial performance and good water-washing resistance.

Description

technical field [0001] The invention relates to the technical field of bras and underwear, in particular to a stand-up cotton washable bra coaster and a preparation method thereof. Background technique [0002] 3D vertical cotton, referred to as 3D cotton, is a new type of environmentally friendly non-woven three-dimensional material. It has a sponge-like three-dimensional structure of vertical fiber network structure or honeycomb fiber network structure, which is different from the parallel fiber network structure of traditional non-woven materials. . [0003] Standing cotton has the advantages of breathability, antibacterial, light weight, and high quality. It has been favored by the market as soon as it came out, and has been applied to many fields. [0004] Underwear is one of the most widely used fields of upright cotton. Because of its breathable and non-toxic properties, upright cotton is favored by the underwear industry, and it has replaced sponge as the main mater...
