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, 88%-94% of polyisophthaloyl metaphenylene diamine condensation polymers, 3%-6% of polyamide, 1.5%-3.5% of anti-yellowing agents and 1.5%-2.5% of anti-ultraviolet agents. The fiber, the method and the fabric have the advantages that the specially selected polyisophthaloyl metaphenylene diamine condensation polymers are used as main materials for the fiber, and accordingly excellent properties in the aspects of the strength, the abrasion resistance, the corrosion resistance, the elasticity and the like of the polyisophthaloyl metaphenylene diamine condensation polymers can be inherited; the whiteness of the fiber can be accessorily improved by the polyamide, 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, accordingly, the fiber is excellent in anti-yellowing property and permanent flame-retardant, high-temperature-resistant and anti-ultraviolet properties and reliable in safety, the fabric is excellent in transmittance, and light transmitted through the fabric is clear and transparent.

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 film and television lighting equipment fabrics on the market are generally composed of reflective cloth, high-density soft light cloth and additional soft light cloth to ensure uniform and soft light. Similar to the light effect created by the sun passing through thin clouds. The light is transparent, the skin feeling is strong, the color saturation is high, the light is soft, the light quality is delicate and the highlights are smooth, and the highlights are clear and focused. The shadow area is extremely soft, the lighting effect is uniform, and the level is reproduced softly. [0003] However, the fabric fiber of this film and television lighting equipment on the market is not resistant to yellowing or has a short yellowing time, is not resistant to high temperature and ul...
