　　衣服的質(zhì)地與兒童的健康有關(guān)嗎?
　　Is the quality of clothes related to children's health?
　　衣服有助于保持恒溫，是保持健康的條件之一。當(dāng)溫度低的時(shí)候，衣服可以保持體溫不流失太多的熱量。高溫不妨礙身體的熱量，并能防止陽(yáng)光對(duì)人體光和熱的不利影響。為了滿足以上要求，服裝要求有保溫、透氣性。
　　Clothes help to keep a constant temperature, which is one of the conditions to keep healthy. When the temperature is low, clothes can keep the body temperature from losing too much heat. High temperature does not hinder the body's heat, and can prevent the sun's adverse effects on the body's light and heat. In order to meet the above requirements, the clothing should have heat preservation and air permeability.
　　這些特征是由服裝面料的質(zhì)地決定的。
　　These characteristics are determined by the texture of the fabric.
　　由于保溫性能好，羊毛是最重要的，其次是棉花，最后是絲綢?？椢锞哂卸嗫仔?，能儲(chǔ)存較多的空氣，因此織物的厚而松的絕緣性好?？椢锏念伾才c絕緣有關(guān)。深色面料反光力小，吸收熱量，淺色面料反光力大，吸收熱量小。所以冬天宜用松、厚、深色的羊毛、棉織物來(lái)做衣服，夏天宜用細(xì)、薄、淺色的麻、絲綢織物來(lái)做衣服。
　　Because of the good heat preservation performance, wool is the most important, followed by cotton, and finally silk. The fabric is porous and can store more air, so the thick and loose insulation of the fabric is good. The color of the fabric is also related to the insulation. Dark fabric has low reflective power and absorbs heat, while light fabric has high reflective power and low heat absorption. Therefore, it's better to use loose, thick and dark wool and cotton fabrics for clothes in winter, and fine, thin and light linen and silk fabrics for clothes in summer.

　　(2)透氣性好的面料能將汗水和污濁的空氣從皮膚中散發(fā)出來(lái)，保持皮膚干燥，調(diào)節(jié)體溫。因此，選擇透氣性好的面料制作兒童服裝，如膠布、油布、透氣性差的塑料布等，不宜用于兒童服裝和尿布，以免影響皮膚的新陳代謝。
　　(2) the fabric with good permeability can emit sweat and dirty air from the skin, keep the skin dry and regulate the body temperature. Therefore, it is not suitable for children's clothing and diapers to make children's clothing with fabrics with good air permeability, such as adhesive cloth, oilcloth and plastic cloth with poor air permeability, so as not to affect skin metabolism.
　　(3)吸濕性由織物的纖維性質(zhì)決定。一般的羊毛、棉纖維吸濕性好，能迅速散發(fā)，使布保持干燥，有利于皮膚的清潔?？椢锏目椩煲才c吸濕性有關(guān)，針織比普通織造吸濕性強(qiáng)。所以孩子宜穿毛毛針織的衣服，既具有柔軟保溫的特點(diǎn)，而其透氣性是否為吸濕性。但不可使用粗羊毛，以免刺激皮膚，人造纖維的吸濕性差，不宜做內(nèi)衣。兒童內(nèi)衣最好是用棉布做的。
　　(3) the hygroscopicity is determined by the fiber properties of the fabric. The general wool and cotton fiber have good hygroscopicity, can quickly disperse, keep the cloth dry, and is good for skin cleaning. The weaving of the fabric is also related to the hygroscopicity. The hygroscopicity of knitting is stronger than that of ordinary weaving. Therefore, children should wear wool knitted clothes, which have the characteristics of soft and heat preservation, and whether its permeability is hygroscopic. However, it is not allowed to use coarse wool to avoid skin irritation and poor hygroscopicity of man-made fiber, which is not suitable for underwear. Children's underwear is best made of cotton.
