世界上第一批合成纤维是于本世纪三十年代问世的,随后,化纤工业得到了迅速的发展。化学纤维的出现极大地改变了人们的穿着结构,同时也说明人类在衣物领域不再完全依赖大自然的恩赐。目前,睛纶、涤纶、丙纶、氯纶等多种化学纤维在国内外广泛使用,越来越多地替代了天然纤维。近些年来,临床实践中发现有少数人对化纤织物过敏。每当穿用化纤衣物,尤其是内衣后,会出现瘙痒不已及皮疹等症候,医学上称为化纤接触性皮炎。这类皮炎主要发生在身体直接与化学纤维接触的部位。患者常感到局部皮肤瘙痒,好似毛扎虫爬一样,尤其在晚间或休息时更为明显。皮炎处有散在的颗粒状小丘疹,伴有或大或小的片状红斑,压迫时不褪色。有时甚至连衣物的界限都看得很清楚,这是本病的一大特点。一旦 The world’s first batch of synthetic fibers was introduced in the thirties of this century, followed by chemical fiber industry has been rapid development. The appearance of chemical fibers has greatly changed people’s wearing structure, but also shows that human beings in the field of clothing is no longer completely dependent on the gift of nature. At present, many kinds of chemical fibers, such as Acrylic Fiber, Polyester, Polypropylene, Polyester and Polyester are widely used at home and abroad, replacing natural fibers more and more. In recent years, a small number of people found in clinical practice allergy to chemical fiber fabrics. When wearing chemical fiber clothing, especially underwear, there will be endless itching and rash and other symptoms, medicine called chemical contact dermatitis. Such dermatitis occurs mainly in the body in direct contact with the chemical fiber parts. Patients often feel itchy local skin, like the hair crawling crawling, especially in the evening or at rest is more obvious. Dermatitis scattered granular papules, accompanied by large or small patchy erythema, do not fade oppression. Sometimes even the boundaries of clothing are clearly seen, this is a major feature of the disease. once
