聚乳酸纤维床上用品功能性测试与评价研究OA

The antibacterial property,anti-mite property,flame-retardant property and deodorization property of polylactid fiber textiles were explored.Fifteen kinds of polylactid fiber bedding products were selected as samples,the performance index were systematically tested and analyzed,including antibacterial property,anti-mite property,pH value,flame-retardant property,low-smoke toxicity,deodorization and odor removal property.The results showed that antibacterial effect of polylactid fiber bedding products against Staphylococcus aureus,Escherichia coli and Candida albicans were significant,with antibacterial rate generally exceeding 98%against Staphylococcus aureus.Containing polylactid fiber sample had certain anti-mite property,while the overall anti-mite effect was limited.The sample pH value was mostly among 4.0 to 7.0,which showed weak acidity and meeting the requirements for skin friendliness.Pure polylactid fiber sample exhibited better flame retardancy and extremely low smoke density in combustion test,and had a certain adsorption and removal ability for various odor chemical components.It is considered that the market potential of polylactid fiber bedding products is great.
