Problems solved by technology

However, PU foam material has poor air permeability and general permanent deformation; poor sweat resistance; easy to hydrolyze; poor weather resistance and easy to turn yellow
The production process is not environmentally friendly. During the use of sponge cups, toxic, irritating or sensitizing chemicals may be released, which is potentially dangerous to women's health;
[0005] 2. Silicone gel material, which has the advantages of soft texture, good elasticity, close to the skin texture, and real touch feeling; but the air permeability is not good, the density is high, and the quality is heavy;
However, its strength is low and it is easy to deform. Cups made of this material have problems in washing, hand feeling, and shaping effects.

Abstract

The invention relates to the field of underwear production, particularly to a foam material for a bra, wherein the foam is prepared by mixing and foaming a raw material A and a raw material B, whereinthe raw material A comprises the following components in parts by weight: 50-85 parts of vinyl silicone oil, 5-50 parts of alkyl silicone oil, 0.2-8 parts of a catalyst, 0-10 parts of a foaming agentand 1-4 parts of a foam stabilizer, and the raw material B comprises the following components in parts by weight: 45-75 parts of vinyl silicone oil, 1-30 parts of hydrogen-containing silicone oil, 5-10 parts of alkyl silicone oil and 0-5 parts of an inhibitor. The foam material of the present invention is environment-friendly, skin-friendly and gas-permeable, has excellent characteristics of goodresilience, low deformation rate, good weather resistance, hydrophobicity, moisture resistance, physiological inertness and the like, has good hydrophobicity and low water absorption, and is especially suitable for swimsuits.

Description

technical field [0001] The invention relates to the field of underwear production, in particular to a foam material used for bras. Background technique [0002] With people's continuous pursuit of healthy and quality life, the debate on healthy underwear has become more and more intense. Especially in recent years, the increase of breast diseases and breast cancer has made people put forward requirements on the comfort, health, safety and environmental protection of bras, and also put forward higher standards for the materials filled in bras. [0003] The commonly used bra filling materials are as follows: [0004] 1. PU foam material is made of polyurethane raw material foam and then made by high temperature molding. It has low density, light weight and good flexibility, so it is widely used. However, PU foam material has poor air permeability, general permanent deformation, poor sweat resistance, easy hydrolysis, poor weather resistance, and easy to turn yellow. The pro...
