Clothing materials will develop allergies

When the weather gets colder, people will start to wrap around scarves. Some people are allergic to wrap around scarves of wool. It has not been long since the whole neck is red, and it is both red. The doctor also said that wool and chemical scrubber are more likely to cause allergies. It is recommended to use scrubber to keep warm and be careful to choose the material. For example, some people need to wear gloves for a long time at work, and they should also pay attention to the material of the gloves. If they are allergic to rubber or chemical fiber, they should choose materials that will not cause allergic reactions.

People who are prone to skin allergies can wear them for a short time at the beginning, about several tens of minutes to confirm that there is no inappropriateness or pain, and then gradually increase the wear time. If used for a long time, it should be removed at appropriate times, then re-wear and adjust.

But sometimes it is not only the material itself that causes allergies, but also the chemical substances that treat the material are harmful to the body. Although fabrics are not necessarily toxic, many chemical synthesis fibers are used to make fabrics nowadays. The fibers themselves will have the smell of raw materials. This is normal, but if they still have a pungent smell after dyeing and making clothes, don't buy them. Fabrics made of cotton, linen, etc. are easily affected by the environment during the production process and mold, so chemicals may be added to make clothes safe, anti-mold or anti-collapse, and may contain formaldehyde ingredients. This should also be paid attention to when purchasing.

So what materials are used to make clothes? Then we might as well come and have a look. The main types of fibers used are divided into natural fibers and synthetic fibers from the source:

●Natural fibers

1. Plant fibers

fibers(Cellulose) are polysaccharides formed by D-glucose units in β 1-> 4 key links. The main chemical elements are composed of carbon, hydrogen and oxygen, such as cotton, linen, etc.

2. Animal fiber

The clothing fabric made from animal hair, skin, veins, etc., tanning, etc. The main component is keratin (keratin), which contains a variety of elements, composed of carbon, hydrogen, oxygen, nitrogen and sulfur.

●Common synthetic fiber types

1. Regenerate fibers of plants, the fibers obtained by treating chemical physics methods. Because the light is similar to linden and has good water absorption, it is also called artificial silk or radiant (Rayon).

2. Artificial fiber

polymers are made of simple organic molecules through chemical methods, so they are called artificial fibers.

▌Nylon: It is the earliest synthetic fiber produced and ranked first in the world in terms of production. Nilong-6,6 is a long-link synthesis fiber formed by polymerization of adipic acid or monomers of adipic acid and adipic chloride and hexanediamine. There are many types of Nilong. In addition to Nilong-6, 6, there are Nilong-6, Nilong-6, 10, Nilong-9, Nilong-11, etc.

▌Dacron: It is a synthetic fiber formed by monomers of ethylene glycol and paraphthalic acid, which are polymerized by esterification reaction and condensation.

▌Orlon: A mixed fiber made of other polyester types is added to a polyacrylonitrile fiber made of a single polymerization of Acrylonitrile.

Although fibers are natural or synthetic, they do not necessarily depend on the bad clothes, if you know that you are prone to adverse reactions to a certain material, then when choosing clothes, you should naturally pay special attention to material specifications. In addition, in addition to paying attention to the material and whether it has a smell when buying, generally wear clothes such as underwear, T-shirts, shirts, etc. Don’t forget to wash them after buying them home before putting them on your body. If there is a fading state, it is best to clean until the water is clean.
