The main features of the Bra spong.

Bra sponge, as an important part of female underwear, has a series of unique characteristics, which can be summarized as follows:

1. Material and composition

The bra sponge is mainly made of polyether polyol, polymer polyol, toluene diisocyanate, water, silicone oil, amine, tin and other raw materials. These materials are treated by complex foaming process and technology, so that the underwear sponge has good rebound effect and tensile resistance effect, and has a long service life.

2. Physical characteristics

A: Resilience and tensile strength: The opening rate of underwear sponge is very high, and the sponge surface is fine. This structure makes the sponge have good resilience and tensile strength, and can adapt to the movement of the body without deformation.

B: Moisture absorption and air permeability: Although the sponge has a certain water absorption, its air permeability is relatively poor, especially in summer or sweating, it may form a hot and humid environment, which has a certain impact on blood circulation.

3. Use and maintenance

A: Comfort: The softness and fit of the underwear sponge is high, which can provide a more comfortable wearing experience. However, it should be noted that the adhesion of the sponge is strong, the detergent may be difficult to completely clean, and the residual detergent may cause irritation to the skin.

B: Cleaning and hygiene: Because sponges are easy to harbor dirt and breed bacteria, they need to be cleaned and replaced regularly. When cleaning, you should choose a mild detergent and rinse it thoroughly to avoid detergent residue.

4. Classification and selection

There are many categories of bra sponges, such as ordinary sponge, high rebound sponge, slow rebound sponge, hydrophilic sponge, permeable sponge, skin sponge, flatulent sponge, etc. Different kinds of sponges have different characteristics and applicable scenarios. When choosing, you should choose according to your personal needs and preferences.
