Abstract
Description
Technical Field
[0001] The invention relates to the technical field of coaster production, and in particular to a coaster and a preparation method thereof, and underwear having the coaster. Background Art
[0002] There are many kinds of bras on the market. There are functional bras developed for people with full breasts. This kind of bra products are made by sewing technology. Because of their strong functionality, they are easy to feel restrained after wearing. Wearing this kind of bra for a long time will cause excessive stress on the upper body muscles and fat of women, which will cause poor local blood circulation and fatigue. There is also a large cup bra product. The cups of this kind of product are made of sponge through high temperature molding. This cup changes the original compression ratio of the sponge, and it is easy to feel stuffy when wearing this kind of bra in summer; there is also a kind of large cup product, which is made of pure single-layer fabric through sewing or molding. Although this kind of product is breathable and light after wearing, the fabric is too thin or too elastic, so women's nipples are easily highlighted, which is very unsightly when worn with other outerwear in summer. Therefore, how to make a bra that can ensure comfort while being breathable and anti-bump effect is a problem that needs to be solved urgently. Summary of the invention
[0003] In view of this, in order to overcome the defects of the prior art, the object of the present invention is to provide a cup pad, which makes the bra fit well and has the effects of breathability and anti-bump.
[0004] In order to achieve the above object, the present invention adopts the following technical solutions:
[0005] The present invention provides a coaster, which comprises a first fabric layer, a first cotton layer, a second cotton layer, a partition layer and a second fabric layer in sequence, the first fabric layer and the first cotton layer are completely fitted together, the first cotton layer and the second cotton layer are completely fitted together, the areas of the second cotton layer and the second fabric layer are both larger than the area of the partition layer, a part of a side of the second cotton layer away from the first cotton layer is fitted with a part of a side of the second fabric layer close to the partition layer, a cavity for accommodating the partition layer is formed between the remaining part of the side of the second cotton layer away from the first cotton layer and the remaining part of the side of the second fabric layer close to the partition layer, and a side of the partition layer close to the second cotton layer is fitted with the remaining part of a side of the second cotton layer away from the first cotton layer.
[0006] By laminating one side of the second cotton layer with the first cotton layer, laminating a part of the other side of the second cotton layer with a part of the one side of the second fabric layer, forming a cavity between the remaining part of the other side of the second cotton layer and the remaining part of the one side of the second fabric layer, and placing a partition in the cavity with the side of the partition away from the second fabric layer laminating with the second cotton layer and the side of the partition close to the second fabric layer not laminating with the second fabric layer, a delamination effect is generated between the part of the second fabric layer not laminating with the partition and the second cotton layer, thereby forming an activity space (cavity), and the partition inside the space can make the second fabric layer (cup lining layer) The second fabric layer is in a suspended (protruding) state, which can effectively prevent the nipple points from protruding; the second fabric layer also has a certain elasticity and is skin-friendly to ensure comfortable wearing. The advantages of this arrangement are: on the one hand, due to the different body shapes of the wearers, the nipple points are in different positions when worn. The cavity arrangement enables the part of the second fabric layer that forms the cavity to have a certain amount of activity space, which is convenient for adjusting the position according to the wearer's body shape, and effectively achieves an anti-convex effect; on the other hand, the cavity formed by the second fabric layer and the middle part of the second cotton layer is equivalent to a hollow layer, which is conducive to air flow, prevents sweating when worn, and makes the bra more comfortable and healthier to wear.
[0007] In some embodiments of the present invention, the material of the first fabric layer is a single piece of breathable cotton that is cut at random, and the first cotton layer is a shaved cotton core, and the material of the shaved cotton core is sponge; the material of the second cotton layer is breathable cotton, and the material of the second fabric layer is also cut at random. The first fabric layer and the second fabric layer are skin-friendly and breathable. Combined with the arrangement of the first cotton layer, the second cotton layer and the interlayer, the entire coaster can achieve the effect of anti-bump while ensuring fit.
[0008] According to a preferred implementation aspect of the present invention, the center of the partition layer and the center of the second cotton layer are located in the same vertical direction.
[0009] According to a preferred embodiment of the present invention, the area of the partition layer accounts for 19.1% to 31.6% of the area of the second fabric layer. If the area of the partition layer is too large, the second fabric layer forming the cavity of the underwear with the coaster will roll up when washed; if the area of the partition layer is too small, the anti-convex point effect cannot be achieved.
[0010] According to a preferred embodiment of the present invention, the diameter of the interlayer is 3.5-4.5 cm, the thickness of the interlayer is 0.5-0.8 mm, and the elasticity index of the interlayer is 4%-6%. The interlayer needs to be resistant to high temperature molding and has low elasticity. In addition, the thickness of the interlayer is very thin. If the interlayer is too thick, the cavity will bulge close to the breast, which may squeeze the nipple point.
[0011] According to a preferred embodiment of the present invention, the material of the partition is Jiaji cloth. Jiaji cloth has very little vertical elasticity but has lateral elasticity. The use of Jiaji cloth for the partition can effectively ensure that it will not be damaged after molding and can effectively isolate the second fabric layer from a part of the second cotton layer to form a hollow layer effect.
[0012] According to a preferred embodiment of the present invention, the thickness of the first fabric layer and the second fabric layer are both 0.8-1 mm; the first cotton layer is a shaved cotton core, the thickness of the first cotton layer is 9.5-10.5 mm, and the thickness of the second cotton layer is 2.5-3.5 mm.
[0013] According to a preferred embodiment of the present invention, the first fabric layer includes a first layer and a second layer that are in contact with each other, the second layer is located between the first layer and the first cotton layer, the material of the first layer is the same as that of the second fabric layer, and the material of the second layer is the same as that of the second cotton layer.

Combined with the arrangement of the first cotton layer 2, the second cotton layer 3 and the interlayer 4, the entire coaster 10 can achieve the effect of preventing bumps while ensuring fit.
[0039] Among them, the thickness of the first fabric layer 1 and the second fabric layer 5 are both 0.8-1mm, preferably 0.9mm; the thickness of the first cotton layer 2 is 9.5-10.5mm, preferably 10mm; the thickness of the second cotton layer 3 is 2.5-3.5mm, preferably 3mm; the thickness of the partition 4 is 0.5-0.8mm, preferably 0.5mm. The thickness of the partition 4 is very thin to avoid its excessive thickness causing the cavity to bulge close to the breast, which may squeeze the nipple point.
[0040] The present invention also provides a method for preparing the coaster 10, comprising the following steps:
[0041] Step 1: Determine the style and size of the coaster 10, and prepare the first fabric layer sheet, the first cotton layer sheet, the second cotton layer sheet, the interlayer sheet and the second fabric layer sheet according to the materials required for each layer of the coaster 10, and cut six first cotton layers 2 with a thickness of 10 mm and a diameter of 8 mm from the first cotton layer sheet, and cut six interlayers 4 with a thickness of 0.5 mm and a diameter of 4 mm from the interlayer sheet.
[0042] The first fabric layer sheet is obtained by bonding a randomly cut first layer sheet and a breathable cotton second layer sheet.
[0043] In addition, it is also necessary to design a corresponding molding die according to the style of the coaster 10. In addition to the conventional concave and convex molds, the mold in this embodiment also includes a first positioning plate for accurately positioning the first cotton layer 2 and a second positioning plate for assisting in aligning the partition layer 4 with the first cotton layer 2. The first positioning plate is provided with a plurality of first through holes extending through its thickness direction at intervals, and the second positioning plate is provided with a plurality of second through holes extending through its thickness direction at intervals. In this embodiment, the number of first through holes and second through holes is six. The diameter of the first through hole is greater than the diameter of the second through hole, and the shape and size of the first through hole match the shape and size of the first cotton layer 2, and the shape and size of the second through hole match the shape and size of the partition layer 4; the plurality of first through holes on the first positioning plate and the plurality of second through holes on the second positioning plate are opened one by one, and the center of a first through hole and the center of a corresponding second through hole are located in the same vertical direction.
[0044] Step 2: After spraying glue on one side of the second layer of the first fabric layer, place the first layer of the sheet that has not been sprayed with glue on the mold.
[0045] Step 3: Place a first positioning plate on the second layer of the first fabric layer and put a first cotton layer 2 into each first through hole, fit one side of the first cotton layer 2 with one side of the second layer, and then remove the first positioning plate.
[0046] Step 4: Spray glue on both sides of the second cotton layer sheet, cover it on the six first cotton layers 2 and adhere it to the first cotton layers 2.
[0047] The area of the second cotton layer sheet is smaller than the areas of the first fabric layer sheet and the first positioning plate.
[0048] Step 5: Place a second positioning plate on the second cotton layer sheet and put a partition layer 4 in each second through hole, fit one side of the partition layer 4 with one side of the second cotton layer 3, and then remove the second positioning plate.
[0049] Among them, the first positioning plate and the second positioning plate are both provided with positioning marks at corresponding positions, and the first positioning plate and the second positioning plate can be aligned as long as the positioning marks between the first positioning plate and the second positioning plate are aligned. Specifically, when the first positioning plate is placed on the second layer of sheet material, corresponding marks are made on the second layer of sheet material according to the positioning marks on the first positioning plate, and when the second cotton layer 3 covers multiple first cotton layers 2, the marks on the second layer of sheet material will still be exposed. When placing the second positioning plate, the positioning marks on the second positioning plate are aligned with the marks on the second layer of sheet material, and then the partition layer 4 is placed in the second through hole, so that one partition layer 4 can be aligned and centered with the corresponding one first cotton layer 2.
[0050] Step 6: Cover the six interlayers 4 with the second fabric layer and press them at a temperature of 180 to 190° C. for 180 to 200 seconds to shape them. After molding and shaping, they are cooled and punched to obtain six coasters 10 of the same size and shape. Figure 2 shown.
