纺织生态与绿色纺织品(二)

Textile Ecology and "Green Textiles" (Ⅱ)

4．2 有害金属由于植物在泥土中吸收到重金属,因此重金属也存在于天然纤维如棉、麻中。纺织品中存在重金属的主要来源是金属络合染料、但是不使用这类染料将导致一些重要颜色的消失,这就是染料加工及印染加工过程中使用重金属的缘故。重金属一旦为人体所吸收,则会有向肝、骨骼、肾、心及脑富集的倾向。当受影响器官其重金属积累到某一程度时便会对人体健康造成巨大的伤害。这种情况对儿童尤为严重,因为儿童对金属有较高的消化和吸收能力。

International Standardization Organization (ISO) decided to carry out ISO 14000 series of International Environmental Standard since 1997. China Technology Supervision Bureau also decided to execute Environmental Management Standard which is equal to the international standard since April 1st 1997. Environmental pollution control is being put into effect involving products design, manufacture, and consuming. Domestic textile dyeing and printing industry must fairly know and recognize the details about textile ecology concerning eco-manufacture, eco-customer, eco-treatment and relevant laws as well as how to produce 'green textiles' to share the market. In this paper, both textile ecology and green textiles are described in details and discussed systematically.
