Beneficiation of Textile Spinning Waste: Production of Nonwoven Materials

ABSTRACT

The textile industry is one of the most essential consumer goods industries, which is also being top environmental polluting. The wastes generated during the production of textile materials can be classified as pre-consumer and post-consumer wastes. In most cases, these wastes are either incinerated or dumped into landfills, which in turn have a factor on the environment and economic growths. To reduce these effects, mitigation measures have to be taken to adopt sustainable textile wastes management and restrain the negative environmental impacts. One of such measures is reprocessing the generated wastes into value-added products. Accordingly, this paper investigated the feasibility of converting the pre-consumer wastes known as spinning wastes into nonwoven products. Chemicals such as polyvinyl alcohol, polyvinyl acetate, cross-linking agent, wetting agent, and acetone were used for the production of nonwoven fabrics through forming chemical bonds between a combed web of short fibers. The conversion of spinning wastes into valuable products will accelerate growth and development by generating additional income and also contributing to environmental conservation.

摘要

纺织业是最基本的消费品行业之一, 也是环境污染最严重的行业. 纺织材料生产过程中产生的废物可分为消费前废物和消费后废物. 在大多数情况下, 这些废物要么被焚烧, 要么被倾倒到垃圾填埋场, 而垃圾填埋场反过来又会对环境和经济增长产生影响. 为了减少这些影响, 必须采取缓解措施, 采用可持续的纺织废物管理, 并抑制负面环境影响. 其中一项措施是将产生的废物再加工成增值产品. 因此, 本文研究了将消费前的纺织废料转化为非织造布产品的可行性. 聚乙烯醇、聚醋酸乙烯酯、交联剂、润湿剂和丙酮等化学品通过在短纤维精梳网之间形成化学键用于非织造布的生产. 将纺纱废料转化为有价值的产品将通过创造额外收入和促进环境保护来加速增长和发展.
