Description

Modified scallop shell biological matrix polyester antibacterial composite fiber

The present invention relates to a composite fiber, in particular to a modified scallop shell biomatrix polyester antibacterial composite fiber with antibacterial, water repellent and biocompatibility, high adhesion, tensile strength and thermal properties.

press! Due to the rapid development of science and technology, there are more and more wastes on the earth, environmental pollution is becoming more and more serious, and the deterioration of the global climate has also been accelerated. With the advancement of environmental protection technology and the vigorous implementation of resource recycling policies in many countries around the world, Relevant resource recovery systems have been established to recycle a large amount of waste. Many relevant biologists have proposed the concept of circular economy, which mainly combines biodegradable raw materials with agricultural wastes and fishery wastes to make products. Repeated use and recycling. When the product has reached the unusable stage, it will return to the ecological circle as a nutrient after raw material extraction, biogas, composting and other procedures to form a circular economy. Therefore, the use of related resources with the concept of circular economy is the development of agriculture. , Forestry, fishery, and animal husbandry related industries are very important, and a large amount of agricultural, aquatic, animal husbandry and food wastes can be recycled and reused in the biological cycle to further eliminate the concept of waste and achieve The important concept of a friendly environment.

my country is surrounded by the sea and the aquaculture industry is very developed. There are at least 20,000 tons of discarded shells every year. There are nearly 140,000 tons of discarded scallop shells in neighboring Korea and nearly 300,000 tons of discarded scallop shells and shellfish every year in Japan. It contains a lot of calcium carbonate (approximately 95% of the shellfish) and the remaining shellfish. After the shellfish is decomposed by microorganisms, it is easy to form harmful substances to the human body and easily produce harmful gases such as hydrogen sulfide and ammonia. Therefore, in order to eliminate the organic substances in the shellfish, the human body or the environment At present, most of the organic matter of waste shellfish is removed by high-temperature calcination. The main components of waste shellfish are generally used as feed additives, household wall materials or soil amendments after high-temperature ashing. In recent years, Related scholars and industry researchers have developed the application of shell extracts in beauty care products, health foods, etc., which cannot really solve the problem of shell waste. Except for a few applications, the amount is actually not high, and it has not been effectively used. Most of the discarded shells can only be buried as waste, which undoubtedly still pollutes the environment.

At present, there are relatively few researches and patents on the application of scallop shells to polymer materials. If a large number of recycled scallop shells can be effectively used in daily life products, it will not only greatly reduce environmental pollution problems, but also create a huge market Economic Value.

In view of this, the inventor of this case researched and improved the above-mentioned needs and deficiencies, and developed a method that can effectively use waste scallop shells to recycle and re-manufacture and add polyester fiber for processing and synthesis, so as to provide a non-toxic, antibacterial and good mechanical properties.

The actual effect is not good.

Another object of the present invention is to provide a composite fiber formed by pulverizing inorganic compound aerogels and ocean shells into nano-particles and then processing them by spinning. The small holes allow water molecules to pass through the gel. And penetration, to achieve the effect of water repellent, and through the inorganic compound aerogel to block the air or foreign water molecules to reduce the thermal conductivity, increase the body temperature, and achieve the effect of heat preservation.

Another object of the present invention is to provide a method that can remove the spores or microorganisms adsorbed by the siliceous sponge needles, so that the originally adsorbed tiny cells or organic matter are removed by a plurality of filtration systems, so that they can be purified to form a clean, cell-free or microorganism-free siliceous material. Sponge needles, to avoid deterioration caused by the addition of silicon sponge needles to beauty products.

Among them, preferably, the polymer compound and the plurality of nano-powdered scallop shell powder nanoparticles after calcination at a high temperature of 800°C to 1200°C are combined by the compatibilizer to form a highly adhesive, surface The modified scallop shell bio-based polyester antibacterial particles with hydrophobicity, biological activity and antibacterial effect.

Among them, preferably, the polymer compound is polylactic acid, polyhydroxy fatty acid ester, propylene-butadiene-benzenediene copolymer, polypropylene, polyethylene, polyterephthalate, polyamide Any one or a mixture of several of the copolymers.
