Interpretation Of NPE Washing And Poisoning Prevention

A few days ago, a number of well-known domestic and international clothing brand products were alleged to contain.

Nonylphenol polyoxyethylene ether

(NPE) residues.

It may cause damage to human health.

NPE

Where does it come from?

Can it be resolved through technical means?

How should consumers guard against it?

With these questions, the reporter interviewed experts from Hebei Province, Hebei University Of Science and Technology.

Yao Ji Ming

Professor.

NPE there are already harmless alternatives to businesses that are abandoned due to cost considerations.

"NPE" nonylphenol polyoxyethylene ether is a surface active agent. It is commonly used as a chemical additive. Because of its good chemical effect and low price, it is widely used in garment processing and washing products production.

The clothes we wear everyday and the washing powder used in our daily life are likely to contain such substances. "

Yao Jiming, an associate professor at the school of textile and clothing, Hebei University Of Science and Technology, said that in order to ensure the soft, smooth, wrinkle free and ironing of finished products, the dye and softeners will be used in the processing of raw materials.

scouring agent

Nearly 20 kinds of additives, most of these auxiliaries are added with NPE components, so the possibility of residual NPE in finished clothes is great.

The NPE residue on clothing can enter the body through inhalation of skin and respiratory tract. It will affect the reproductive system of the human body, and it is difficult to degrade. Once it enters the environment, it will cause damage to the ecological environment system.

Yao Jiming said that "environmental protection is harmless".

Isomeric alcohol surfactants

"It can replace NPE, but the price of the substitute is higher than that of NPE. Moreover, the use of this material is also required for the technical level of the manufacturer. Most enterprises do not need to consider the cost and operation convenience.

However, as long as clothing manufacturers choose environment-friendly chemical raw materials in the processing of clothes, NPE residues can be avoided.

Functional clothing is highly toxic.

Yao Jiming introduced that in addition to NPE, there are still many opportunities for clothing pollution in the whole production process.

Many clothing raw materials such as cotton, if in the process of planting a large number of pesticides, even after repeated processing, there will be a small amount of pesticide residues, skin often contact can also cause harm.

In addition, dyes, fixative and finishing agents used in the process of clothing dyeing and shrinking water treatment contain formaldehyde, decomposable aromatic amines and other substances and heavy metal ions that induce skin allergy, respiratory diseases and even carcinogenesis.

In this regard, Yao Jiming suggested that consumers should not blindly pursue the multi-function clothing, whether it is cotton or polyester fabrics, the more functions, the more processing procedures, the more chemical raw materials used, the greater the chance of infection of toxic substances.

When choosing clothing, especially underwear and children's clothing, consumers should try their best to choose coloring agents to use less light colored clothing. The newly bought clothes should be washed before they wear. "Because NPE has good water solubility, it can remove most of the residual harmful substances by washing."
