Computer-aided visualisation analysis of biodegradable fibre materials in styling design

Traditional polyester products are difficult to degrade and cause serious environmental pollution. Finding environmentally friendly materials to replace polyester has become a current research hotspot. This paper uses computer-aided design (CAD) software and finite element analysis (FEA) software to carry out detailed three-dimensional modelling and mechanical properties simulation analysis of PLA, PHA and PBS materials. The research results show that PLA and PHA degrade the fastest in a composting environment. After 90 days, only 20% of PLA's weight remains, and PHA only takes 90 days to completely degrade. However, in a composting environment, PBS still has 40% of its weight after 90 days, indicating that it has the highest durability. The experimental results show that PLA material has good effect in making curtains. Comfort, moisture absorption and breathability make PHA suitable for mattresses. PBS has good durability and softness, making it a good choice for making bed curtains.
