Common Allergenic Substances In Textiles And Their Sensitization Pathways

As an important daily necessities,

Long term close contact with the human body.

With the development of technology, manufacturers have been innovating not only in varieties of colors, textile materials, but also in various functional textiles.

This series of new technologies, new materials and the use of various functional auxiliaries inevitably bring some security problems, which have been paid much attention by government organizations and consumers.

Among them, with the increase of consumer complaints, the problem of sensitizing substances in textiles has attracted increasing attention.

Sensitizing dyes are the most sensitized substances in the textile field at present. They can cause human allergy through various ways such as skin, respiratory tract and mucous membrane.

At present, the newest version of Oeko-Tex Standard 100 standard contains 21 kinds of sensitized dyes, all of which are disperse dyes, of which the largest number of blue dyes are 8 disperse blue 1, 3, 7, 26, 35, 102, 106 and 124; the second is yellow, and there are 124 species, namely disperse yellow trap, trap, yellowish, orange, and orange; orange species are scattered orange, Chinese, Chinese, Japanese and Chinese; red species are scattered red, yellow and orange; Brown is a kind of disperse Brown palm, these dyes have been proved to be sensitive to human body.

In addition, there are reports about human allergies caused by some reactive dyes and acid dyes, but few are listed in relevant standards.

The dispersion listed above

Sensitization routes to the human body are usually skin contact, characterized by pruritus, allergic dermatitis, eczema and so on.

In recent years, there has been an increasing trend of such sensitization reactions. This is due to the increase in the proportion of allergic substances in the crowd caused by environmental pollution. On the other hand, such problems have not yet attracted enough attention from the public. In the production process, sensitizing dyes are still used. Data collected from the inspection work in recent years: the sensitization cases caused by school uniform products, especially summer sports uniforms, account for a large proportion.

Especially in the sultry environment of the southern region, students wear such products for intense sports activities, which is likely to cause skin allergy.

Possible sensitized additives residues.

In order to improve the fabric performance and improve the production technology and other aspects, textile technology is widely used in various chemical synthesis auxiliaries. Many chemical compounds have sensitization to humans and animals, especially for some susceptible people.

The sensitizing routes of the textile auxiliaries on the human body are complex and diverse. First of all, it is a common contact sensitization. For example, in summer sweating, because of the low degree of combination between auxiliaries and textiles, it is easier to induce allergic symptoms with sweat and other substances. Because of the difference between dyes and auxiliaries, the combination of auxiliaries and fabrics is less concerned.

In addition, because the residue of additives is more common in textile production and processing stage, it has more obvious impact on workshop workers, which has been easily neglected.

Alkylphenol polyoxyethylene ether is a widely used surfactant in textiles, and has high surface activity.

In general, they are allergenic to varying degrees, and lead to human allergies in many ways, such as damaging the intercellular fat and stratum corneum of skin cells, stripping and dissolving cells, causing dry and itchy skin, and penetrating into the skin, causing dermatitis and protein pH absorption.

When the fabric contains a lot of microfiber, the cause of sensitization is likely to be the combination of alkylphenol polyoxyethylene ether in the fiber, and the large amount of fiber particles coming into the human body when cutting, leading to the emergence of allergic symptoms of the tailoring workers.
