So many years down the line, why bra cups inside the sponge, why sponge bras have always occupied the absolute market. When everyone is used to all this, suddenly, the Internet crazy rumors sponge bra toxic, to avoid some panic, after all, have been wearing sponge bra.

First, what exactly is the sponge made of
Simply put, the sponge is organic polymer polyurethane foam, a mixture of different chemical raw materials mixed and reacted to make a mixture of foam.

Foam sponge

sponge

The main raw material for making sponge.

Polyurethane emerging organic polymer materials, both polycarbonate, polyacetal, polyamide, modified polyphenylene ether after the "fifth largest plastic"

PPG (polyether) is very low toxicity, commonly used as drug excipients, antistatic agents and emulsifiers, in the mouth, nasal spray, eye and ear drops and shampoo are often used.

POP (polyether polyol) adhesives and elasticizers

TDI (toluene diisocyanate) highly toxic chemicals

MC.T9 (tin) chemical additives

A33 (amine) blowing agent

Silicone oil Foam stabilizer

Through these chemical materials, we can develop different kinds of soft and hard foam sponges in different ratios to suit different fields of use.

Sponge types are.

Shaped cotton, suitable for swivel chairs, sofas, seat cushions, back cotton, there are also a small number of armrests are also made of shaped cotton, sponge elasticity hardness can be adjusted, depending on the different products to adjust, generally seat cotton harder, higher density, back cotton second, pillow cotton softer.

Foam cotton, polyether foam molding, like foam bread, the application is very wide. One of them is called fire-resistant cotton (flame retardant cotton), in fact, is in the foam cotton foam before the material formula to add fire retardants, such as chlorine, bromine, so that when the sponge fire can produce fire smoke, play a fire-retardant role.

Rubber cotton, the main material is natural latex raw material foam, it has rubber properties, excellent elasticity, good resilience, will not be deformed, but the price is not expensive, 3 to 4 times higher than the foam cotton.

Recycled cotton, belonging to the polyurethane products industrial offcuts recycling, do not mistake recycled sponge is used sponge, that is a big mistake. Formal and responsible manufacturers are never to use the sponge recycled from the private sector, never industrial first-hand raw materials. Therefore, the smell of recycled sponge is partly due to the use of old sponge processing, which is the problem of corporate conscience.

And the sponge in the bra is the foam cotton (ordinary sponge bra) or recycled cotton (upright cotton, memory foam bra).

Second, why would say that the sponge is toxic
Said sponge is toxic for no other reason than.

One, the synthetic sponge chemicals TDI (toluene dihydrogenate) is toxic.

Second, the sponge will have a pungent smell after burning.

Third, wearing a sponge bra nipples will turn black.

In fact, this statement is untenable

1, synthetic sponge chemical TDI toxic, can not prove that the sponge itself is toxic, otherwise all the plastic food packaging bags can be said to be toxic.

2, the sponge will have a pungent smell after burning, also can not prove that the sponge is toxic, or most of the clothing can be said to be toxic, because they burn the same pungent smell will be issued.

3, wearing a sponge bra nipples will become black more can not prove that the sponge toxic, because even if not wearing a bra, most adult women nipples will become black, which is a normal physiological phenomenon.

4, the basic common sense of the bra production process, the sponge used in the bra and not directly against the skin, the sponge and the skin is separated by a layer of cotton.
,
5, the lingerie industry has strict quality control standards for bras, such as chinaqualitycertification referred to as C Q C, to meet the standard of direct wear, direct contact with the skin safety requirements.

Third, how to buy sponge bras
To say how to buy a good sponge bra, in fact, for the time being, there is nothing very effective method.

Some people say that when buying a sponge bra, feel its touch and elasticity, touching it should have a soft touch, and ductility. I'm a mother, what is this feeling? Do you, me and her feel the same?

High quality sponge

High quality clean sponge bra pads

Some people say that the bra will be cut open to know the difference, who has seen which business stores will let consumers do so? Of course, now there are many businesses will open one beforehand to prove the quality of their own sponge, so that customers can buy with confidence.

Some people even say that the sponge with fire to burn the bra, not to say, really the more said the more unreliable.

Various sponge cups

All kinds of sponge cup cup type

So, there is also the only one left that is not the way to go, choose a well-known brand bra. The brand may not always be good, you know, the quality is quite different but the visibility is very different, that brand this thing is a lot of promotion and money out.

In fact, it is not so serious, the vast majority of manufacturers still have the most basic industry standards and ethics.

Fourth, the sponge bra how to wash and care
In fact, in addition to those poor quality sponge bra, qualified sponge bra will also appear some bad smell, moldy spots, and this is why?

Yes, this and our daily sponge bra washing method has an inexcusable relationship, there are two reasons.

1, due to the sponge honeycomb structure, the organization is tight, not easy to breathe, sweating, water molecules stored in the honeycomb and produce a stifling feeling, not only is not easy to dry, and easy to hide dirt and become a hotbed of bacterial growth.

2, the strong adsorption of the sponge, when you clean it, the sponge has been quietly absorbing those wash clothes, soap and other cleaning products.

So, it is highly recommended that girls should try and wash their sponge bras as many times as possible to reduce the residue of dirt and detergent, and then try to squeeze the water in the cup sponge by hand, and never use a dehydrator type to dry the bra and destroy the cup shape!

In addition, sponge bras need to be dried thoroughly.
