【摘要】 目的 为预防制衣行业中使用人造革面料造成二甲基甲酰胺(DMF)中毒提供科学依据。方法 对3种不同厂家生产的人造革面料中二甲基甲酰胺污染情况进行测定,对不同品种面料、不同温度条件下二甲基甲酰胺挥发24h进行动态观察和实验室模拟试验及生产车间现场测定。结果 发现人造革面料中二甲基甲酰胺污染普遍存在,浓度为27～39μg/cm~2,24h挥发消减率达96％～98％,不同温度下的消减率有差异,温度低时面料中的二甲基甲酰胺消减较慢。实验室模拟试验,空气中二甲基甲酰胺浓度可高达19mg/m~3,生产车间空气中二甲基甲酰胺浓度为(0.72±0.97)mg/m~3。结论 制衣加工中应注意预防二甲基甲酰胺中毒,并应采取有效预防措施。更多还原

【Abstract】 [Objective] To provide scientific basis for the prevention of DMF toxication caused by artificial leather. [Methods] The concentration of DMF in three kinds of artificial leather from different factories was measured, and the volatilization of DMF in different materials and temperatures was examined dynamically in 24h. [Results] The concentration of DMF in artificial leather was 27 - 39 μg/cm3, the e-vanish rate in 24hs was 96% - 98% , and the evanish rates in different temperatures were different. The lower the temperature is, the smaller the evanish rate is. The DMP concentration in the experimental space and in workshops were 19 mg/m3 and (0.72±0.97) mg/m3 respectively. [Conclusion] Effective measures should be taken to prevent DMF toxication in garment factories using artificial leather.更多还原
