Onko aramidi orgaaninen kuitu? Mikä on orgaaninen kuitu?

Orgaanisilla kuiduilla tarkoitetaan kuituja, jotka on valmistettu orgaanisista kuiduista, mukaan lukien polyesteri, akryyli, nailon, polypropeeni ja korkean suorituskyvyn kuidut, mukaan lukien aramidi, ultrakorkean molekyylipainon polyeteenikuitu (UHMWPE-kuitu), polyparafenyleenibentsobisoksatsolikuitu (PBO-kuitu), polybentsimidatsolikuitu ( PBI-kuitu), polyfenyleenipyridiinidi-imidatsolikuitu (M5-kuitu), polyimidikuitu (PI-kuitu) jne.

Aramid fiber, or aromatic polyamide fiber, is a linear high-performance organic fiber whose main polymer chain is mainly composed of amide bonds and aromatic rings, mainly including meta-aramid fibers and para-aramid fibers. The meta-aramid fiber is mainly polyphenylene isophthalamide (PMIA), which is often called aramid 1313 in China. It has excellent heat resistance and flame retardancy, and is mainly used in aviation, military, high temperature Filter materials and safety protective clothing, etc.; para-aramid fiber is polyparaphenylene terephthalamide (PPTA) fiber, which is often called aramid 1414 in China, which is also known as high-strength and high-modulus aramid fiber in daily life. , has the characteristics of high strength, high modulus, high temperature resistance, excellent flame retardancy and chemical stability, and has very important applications in the fields of aerospace, national defense and military industry, marine development, high-speed transportation, environmental protection and new building materials. , is currently the most widely used high-performance organic fiber. However, due to the limitations of the fiber structure, PPTA fibers have poor light resistance, will degrade under ultraviolet light radiation, and have poor fatigue resistance, compression resistance and dyeability.
