Fine denier polyamide 512 fiber

2024-09-06News 5000

Recommendation Reasons

A new variety of fine denier long-chain polyamide fiber.The fabric integrates the characteristics of lightweight, wear-resistance, low temperature resistance, and ultraviolet resistance, etc., being favored by the lightweight down jacket market.

Processing Technology

Diamine monomers from biomass raw materials and long-chain binary acid monomers

prepared by biological method are used to polymerize into silk-like long-chain polymer

according to the molecular structure of natural silk by synthetic biology method, and then the

fiber product is produced through low-temperature melt spinning process.

The downstream application guidance

Dyeing and finishing: Dyeing with acid dyes or metal complex dyes at the dyeing temperature

of 98-105°C; When the temperature reaches 80℃, the dyeing heating rate should be reduced

to within 1.0C/min

Heat-setting and post-finishing: The temperature for heat-setting and post-finishing should be

controlled within 160℃

Q: What are the characteristics of the down jacket fabric woven with fine

denier polyamide 512 fiber?

A: At present, the high-count and high-density 420T down jacket fabric is developed based on the fine denier polyamide 512 fiber, and has the characteristics of light weight, high strength, wear resistance, anti-drilling, and low temperature resistance. Compared with other fibers such as fine

denier polyamide 6, its tearing strength is higher and its can maintained better flexibilityat the low temperatures of20~30℃
