Heat-shielding and Antin ultraviolet Polyamide 6 Fiber

2025-03-20News 680

Reasons for recommendation

The fiber achieves the multi-functional integration,possessing heat-shielding, anti-ultraviolet, thermoregulating, and moisture

permeability properties, etc. It can effectively protect the skin from

ultraviolet injury while addressing issues such as sun protection and

stuffiness in summer.

Preparative technique

The composite nano-functional master batches with heat-shielding,

anti-ultraviolet and thermoregulating properties are blended with

polyamide 6 chips, and the spinneret plate with a profiled cross-section is used to produce the fiber through melt spinning.

The downstream application guidance

Design an appropriate fabric weaving structure: It is recommended that the fiber content accounts for more than 60% to ensure the stability of its functions.

Dyeing and finishing: It is recommended to set the washing temperature of the gray fabric at 80~90°C, control the dyeing pH within the range of 5~6, and set the fabric surface setting temperature at 192~200°C.

Q: The fiber belongs to multifunctional composite fibers. What are the

function principles of the fiber?

A: The composite functions of this fiber originate from the additives, its profiled section, and the properties of the materials themselves. The heat-shielding,anti-ultraviolet and thermoregulating properties are derived from the added functional master batches, which can reflect and block near-infrared and ultraviolet rays, effectively reducing the heat generated by the absorption of near-infrared and ultraviolet rays. The moisture permeability and moisture-wicking performance are derived from the specially designed fiber section,which can enhance capillary action for rapid moisture transport, aiding in lowering body temperature.
