A non-film-coated breathable silicone breast pad and its manufacturing method

Abstract

Provided in the present invention is a non-film-coated breathable silicone chest pad, comprising a silicone chest pad body, wherein the silicone chest pad body comprises at least an organosilicone gel bottom layer and an organosilicone gel surface layer stacked in the thickness direction from the bottom to the top and bonded together with each other, the hardness of the organosilicone gel bottom layer is greater than the organosilicone gel surface layer, the organosilicone gel bottom layer contains a polymer lightweight microbead filler, and ventilation holes run through the silicone chest pad body in the thickness direction. Also provided in the present invention is a method for manufacturing this kind of silicone chest pad through two injection mouldings using a moulding die having the same die and two different punches to give the silicone chest pad body and then punching out air holes on the silicone chest pad body using a hole-punching mould. The silicone chest pad of the present invention has the advantage of being lightweight, breathable, and easy to clean and having a highly soft surface. The production method provided by the present invention can conveniently make changes to the shape of the product, thus making it easy to form a series of products.

Description

technical field [0001] The invention relates to a silicone breast pad and a manufacturing method thereof, in particular to a non-film-coated breathable silicone breast pad and a manufacturing method thereof. Background technique [0002] The current underwear chest pads (generally used as bra accessories) can be divided into three types in terms of materials: sponge (including surface patch) shaped chest pad, non-woven fiber cotton (including surface patch) shaped chest pad, film bag (including surface patch) There are four types of breast pads: surface patch) built-in filler chest pads and film-coated ordinary silicone gel breast pads. And these types of breast pad products have their own obvious defects: sponge (including surface patch) shaped breast pads are easy to yellow, easy to deform (especially in the washing process), and poor durability; non-woven fiber cotton (including surface patch) stereotypes Although the breast pad basically solves the yellowing problem of ...

AI Technical Summary

Problems solved by technology

And these types of breast pad products have their own obvious defects: sponge (including surface patch) shaped breast pads are easy to yellow, easy to deform (especially in the washing process), and poor durability; non-woven fiber cotton (including surface patch) stereotypes Although the breast pad basically solves the yellowing problem of the sponge material, it lacks the elastic feel, especially after washing, the deformation degree is higher and the durability is worse; There are no obvious defects, but because of the airtightness of its film material, it is easy to cause the body to feel stuffy, and it is not as soft and comfortable as other products, and it cannot effectively form a curved shape that fits the human body; Although silicone gel breast pads basically solve the problems of hand feel, deformation and durability, there are still problems of excessive weight and poor air permeability of the film. In addition, the outer film is generally made of TPU, and there is also the problem of material hydrolysis. Not suitable for water cleaning
