Abstract

The invention relates to the field of fibers for fabrics, in particular to a fiber, a method for manufacturing the same and a fabric with the fiber. The fiber mainly comprises, by weight, 89%-92.5% of polyisophthaloyl metaphenylene diamine condensation polymers, 5%-7.5% of polyethylene glycol terephthalate, 1.5%-2.0% of anti-yellowing agents and 1.0%-1.5% of anti-ultraviolet agents. The fiber, the method and the fabric have the advantages that the fiber is excellent in performance in the aspects of the strength, the abrasion resistance, the corrosion resistance, the elasticity and the like; the whiteness of the fiber can be accessorily improved by the polyethylene glycol terephthalate, the fiber is accessorily printable owing to the polyethylene glycol terephthalate, the anti-yellowing agents with specific contents and the anti-ultraviolet agents with specific contents are added into the fiber, various raw materials are good in compatibility, coordinative matching between the various raw materials can be enhanced, and accordingly the fiber is high in strength, excellent in alpha, beta and gamma ray resistance and ultraviolet ray radiation resistance and reliable in safety, is abrasion-resistant, anti-yellowing, high-temperature-resistant and printable, and is permanently flame-retardant.

Description

technical field [0001] The invention relates to the field of fabric fibers, in particular to a fiber, a preparation method thereof, and a prepared fabric. Background technique [0002] At present, the fibers of special clothing and advertising fabrics on the market have poor tear fastness, poor hand feeling, low temperature resistance, poor UV resistance, and no safety, fire resistance, electrical insulation and other properties. [0003] In order to solve the above problems, it is generally used to add some chemical additives to the fabric to make the product have a short-term effect, and the fabric itself has no function, but the fabric after this post-treatment is washed with water several times or for a period of time. After use, the product returns to its original state. Therefore, need badly a kind of safer and more reliable lining occurs, to satisfy people's demand. [0004] In view of this, the present invention is proposed. Contents of the invention [0005] Th...
