Looking Forward To The Textile Industry In The Low Carbon Era

In order to make people wear colorful clothing, the textile must be passed through dyeing and printing processes.

As far as I know, about 15% of the dye is released directly into the water, making the river "coke".

According to Professor Chen Wenxing of Zhejiang Sci-Tech University, dyestuffs are complex in composition, high in concentration and chromaticity, and most of them are difficult to biodegradation. They also include a variety of organic compounds which are biotoxic or carcinogenic, teratogenic and mutagenic.

In order to reduce environmental pollution caused by printing and dyeing, scientists have tried various methods.

Professor Zhang Keqin, from the National Engineering Laboratory of modern silk, Soochow University, has found inspiration from the gorgeous butterfly wings and peacock feathers. Butterfly wings and peacock feathers have photonic crystal structures that reflect or refract sunlight, resulting in various colors.

In fact, there are many one-dimensional or two-dimensional photonic crystal structures in many natural organisms.

If we can develop photonic crystals

At present, the large diameter vascular prosthesis made of polyester and expanded polytetrafluoroethylene (>6 mm in diameter) has achieved good clinical results.

The team led by Xu Weilin, Vice Chancellor of Wuhan Textile University, worked with the hospital. The tubular fabric was used as a blood vessel scaffold to simulate the three layer structure similar to the human blood vessel structure, and the composite small-diameter artificial blood vessel with drug release function was prepared.

It is reported that this artificial blood vessel has shown good long-term patency and biocompatibility in animal experiments.

In addition to artificial blood vessels and artificial skin, future medical textiles will become more intelligent.

"Smart wound dressings can be used to determine wound healing before dressing removal. Smart bandages can control the laying of bandages, and can record pressure values during treatment and long-term clinical trials."

Li Lingshen, director of China Industrial Textiles Association, believes that information science will increasingly integrate into biomedical materials, and the intellectualization of medical textiles will be gradually realized.
