Application of protein biodegradable materials

Author:QINSUN Released in:2023-03 Click:123

The application and development of protein biodegradable materials has been a
research hotspot in the field of textile materials in recent years, but how to
avoid the use of blending or cross-linking to produce water-stable protein
textile products , The use of protein materials to obtain non-traditional
textile products has always been a research problem in the field of
biomaterials. A protein is an organic compound consisting of an organic amino
acid group and a peptide bond (combined by a group and an amino group). Strong
film-forming ability. Protein materials have both hydrophilic and hydrophobic
segments in structure and have strong affinity for most protein fibers and
thermoplastic fibers; at the same time, protein materials are rich in the number
and types of functional groups, which are easy to modify and ideal as loading
raw materials. . Protein is a naturalk polymer with abundant reserves. When used
as a raw material for textile materials, it has the advantages of being
renewable, degradable, non-toxic and cheap.

The preparation of wheat protein and soy protein fibers and membranes has
lower requirements on the solubility of proteins, and some protein
macromolecules may exist in the solution in the form of random coils, the
presence of partially insoluble protein particles can also play a role similar
to that of reinforcement in composite materials, increasing the strength of the
material, but at the same time it will lead to a larger fiber diameter. However,
protein loading requires a higher degree of protein solubility so that the
loading can better penetrate the fiber and play a role in binding. Therefore, it
is of great importance to develop a dissolution method with low toxicity and
controllable protein degradation for the preparationof protein load. However,
the degree of polymer solubility, molecular weight, and multi-yarn type directly
affect multi-material loading speed and yarn performance. Therefore, using
alkali-dissolved protein to prepare the cargo requires hydrolysis while
controlling damage to the backbone of the molecule to obtain a protein solution
with moderate molecular weight and moderate viscosity.

Inexpensive, good film-forming properties, stickiness and easy breakdown make
vegetable protein an ideal alternative to PVA filling. However, the film-forming
properties of protein on the fiber surface and the multi-yarn performance after
coating have not been investigated. Research into the biodegradability of
proteins in wastewater treatment plants is also necessary. Based on the research
base of animal and vegetable protein fiber development, dhis research uses the
protein present in large quantities in agricultural by-products and animal hair
and other waste as raw materials to develop new protein cargoes that are
competitive in terms of performance and price . The animal and vegetable protein
material developed in this paper is a textile material with excellent
performance, high added value and low carbon emission.
