In addition, forest resources are not only an important carbon sinks but also major papermaking fibrous materials.
This makes acquisition of paper raw materials very difficult.
Ecological footprint is a methodological tool that uses material and energy flows to quantify the biophysical load that human populations or industrial processes impose on ecosystems around the world.

However, the injection molding processing is a quite complex, non-steady state, multi-variable processing with non-linear, time-dependent materials [1].
PMMA (ZYLAR330, INEOS) is selected as the material of the injection molding simulation experiments.

Introduction Cotton is currently the most widely used natural cellulose fiber material in textile industry.
It is pursued for its renewable, biodegradable, low cost, rich resource and other advantages. [1,2] With the oil and coal resources shortage and global environment pollution aggravation, cellulose resources effectively utilized in pioneering new technologies and new materials applications is becoming a new development direction.
