Technical Field

The invention relates to the technical field of fibers, in particular to an ultra-cold sensitive yarn containing bio-based PA and bio-based PE.

Background

With the continuous development of living standards and technologies, the comfort requirements of people on seats and cushions are higher and higher, and the materials of the ice silk or the cushions with high heat conductivity are also continuously developed. The traditional ice silk is viscose fiber, and the fiber has good hygroscopicity and air permeability and has certain smooth and cool feeling. However, the ice silk as a kind of cellulose fiber is still gradually hardened by aging influence of air and sunlight even after being formed by complex physical and chemical treatment, and the heat conduction efficiency is limited, so that the cool feeling of the cushion can not be maintained for a long time, and meanwhile, the ice silk is difficult to pollute by sweat stains and the like in the use occasion and is very easy to breed bacteria.

Disclosure of Invention

The invention aims to overcome the technical defects and provide the super-cold-feeling silk containing the bio-based PA and the bio-based PE, which has higher heat conduction efficiency and better antibacterial activity.

In order to achieve the purpose of the invention, the invention adopts the technical scheme that: the super-cold-sensing wire containing the bio-based PA and the bio-based PE is of a skin-core composite structure, a core layer material of the skin-core composite structure is obtained by blending and modifying the bio-based PA, a heat conduction material and a flame retardant, and a skin layer material of the skin-core composite structure is obtained by blending and modifying the bio-based PE, the antibacterial agent and the flame retardant.

Further, the core structure is hollow, and the core extrusion is designed through an extrusion die head, so that the interior of the core structure is hollow.

Further, the heat conduction material is one or more of nano aluminum powder, nano aluminum oxide, nano aluminum nitride, graphite and carbon fiber.
