概括

织品的洗释放出微塑料纤维 (MPF),而编织的烯酸面料脱落最多. 取消可选的洗前循环可以显著减少服装的MPF污染.

科学领域:

环境科学环境科学
材料科学材料科学材料科学
织工程织工程织工程

背景情况:

织材料是微塑料污染的主要来源.
洗织品是释放微塑料纤维 (MPF) 的主要方法.

研究的目的:

调查织原材料,织物结构,厚度和重量对洗过程中的MPF释放的影响.
为了比较从处女和回收聚中释放的MPF.
为了评估在不同洗阶段 (洗前与肥/冲洗) 释放的MPF.

主要方法:

使用模仿家庭洗衣的洗衣程序 (10分钟前洗,35分钟在40°C下用肥/冲洗).
通过过洗水来收集MPF,并在宏观图像上使用Image J软件进行视觉计数.
测试了各种织品类型 (亚克力,聚胺,聚,回收聚,聚烯) 和织物结构 (织物,针织).

主要成果:

针织织物释放的MPF比织物少. 编织的烯酸 (A3-w) 的释放率最高 (2405 MPF).
随着织物厚度和基础重量增加,MPF的释放量增加.
回收聚释放的MPF比原始聚 (908个MPF) 多 (1193个MPF).
可选的洗前循环释放的MPF比肥/冲洗阶段多得多.

结论:

回收聚,虽然看似环保,但可以比处女聚更为微塑料污染做出贡献.
织物结构 (织造与针织),材料类型和物理特性显著影响MPF脱落.
消除洗前循环是减少微塑料纤维释放到废水中的关键一步.

关键词:

微纤维是一种微纤维.微塑料是一种微塑料.织品织品织品织品洗洗洗洗洗废水是废水,废水就是废水.

Types of Step-Growth Polymers: Polyesters

Types of Step-Growth Polymers: Polyesters

The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...
