People take the reproducibility of production raw materials in each stage as an evaluation standard, use the pollution degree in production as an evaluation index, and then put the textile waste after the end of the consumption process. Degradable, recyclable.
As an evaluation index, each index is scored on a 5-point scale with a maximum of 30 points, which is an ideal fiber ecological index.

Fiber ecological index = actual ecological index of fiber / ideal ecological index of fiber = actual ecological index of fiber / 30
