Abstract

The invention relates to a synthetic fibre with the functions of heat storage, warm keeping and health protection. The fibre consists of a master batch with the functions of heat storage, warm keeping and health protection and a fibre grade resin slice, wherein the master batch comprises the following components in percent by weight: 30-70 percent of carrier resin, 10-40 percent of zirconium carbide powder, 3-8 percent of silane coupling agents, 5-10 percent of solid coupling agents and 15-18 percent of dispersing agents. The method for preparing the fibre comprises the step of preparing the master batch with the functions of heat storage and warm keeping as well as the step of spinning. The invention has the beneficial effects that the zirconium carbide can be used for absorbing visible light and near and far infrared light, the concept of applying the absorption and thermal conversion characteristics of the zirconium carbide to the heat storage and warm keeping fibre is different from the traditional fibre, and the heat storage and warm keeping effects are obviously improved. The method for preparing the fibre has peculiar process for treating the zirconium carbide, thus causing the spinning process to be smoothly carried out and ensuring the fibre quality and the durability of the heat storage function.

Description

Heat accumulation thermal health care synthetic fiber and manufacture method thereof

(1) technical field

The present invention relates to a kind of synthetic fiber and manufacture method thereof of field of textiles, particularly relate to a kind of heat accumulation thermal health care synthetic fiber and manufacture method thereof.

(2) background technology

Along with improving constantly of people's living standard, also more and more higher to the needs of health-care clothing, sportswear, therefore ventilative, saturating wet, waterproof and various functional fiber have also appearred.Its principle one of heat accumulation thermal fiber or fabric is to prevent hot body heat outflow, the 2nd, and provide heat to be absorbed and pass to human body by the outside by fiber or fabric.The former mainly is that its effect is not ideal enough by the still air layer between fiber or fabric or the little purpose that reaches adiabatic heat-insulation of thermal conductivity factor of fiber.The latter reaches the purpose of heat storing and heat preserving by fiber or fabric to the absorption of outside heat, and its heat-accumulating and-keeping effect is higher than the former far away, thereby becomes the main research and development target of present heat storing and heat preserving fiber or fabric.

(3) summary of the invention

In view of above-mentioned purpose, the invention provides a kind of heat accumulation thermal health care synthetic fiber and manufacture method thereof.

Technical scheme of the present invention is to realize like this.

A kind of heat accumulation thermal health care synthetic fiber, this fiber is made of heat accumulation thermal health care master batch and fibre resin section, described functional agglomerate comprises following component, all be weight percentage: vector resin 30～70%, zirconium carbide powder 10～40%, silane coupler 3～8%, solid coupling agent 5～10%, dispersant 15～18%.

Its particle diameter 50～100 nanometers of described zirconium carbide powder.

Described solid coupling agent is a kind of and silane coupler combination in aluminic acid ester, the titanate esters composite coupler.

Described dispersant is any among PE macromolecule wax, PP molecular wax, the EVA.

Described vector resin is any in polyamide, modified polyamide, the PP resin.

The manufacture method of this fiber comprises the following steps:

(1), preparation heat accumulation thermal functional agglomerate: soak into processing with adding silane coupler in the zirconium carbide powder, a kind of mixed stove of height of putting into according to the above ratio in powder after soaking into, titanate coupling agent, the aluminate coupling agent is stirred, activates, add vector resin then, stir, add dispersant again, stir, after twin-screw melt extrude, functional agglomerate is made in cooling.

(2), spinning: the above-mentioned functions master batch is carried out drying, make its moisture, add the fibre resin section then,, through post processing processing, promptly make heat accumulation thermal health care synthetic fiber again by the melt extruded spinning less than 30ppm.

Usefulness of the present invention is: zirconium carbide can absorb visible light and nearly far red light, and the theory that its absorption and hot transfer characteristic are used for the heat accumulation thermal fiber is different from traditional fibre, and its heat accumulation thermal effect also is significantly increased.The manufacture method of this fiber has its unique structure in the processing of zirconium carbide, spinning process can be carried out smoothly, has guaranteed the durability of quality of fiber and heat accumulation function simultaneously.

(4) specific embodiment

Below in conjunction with embodiment the present invention is described further.

Following table provides embodiment, according to the method manufacturing of this programme.

Table 1

	Embodiment 1	Embodiment 2	Embodiment 3	Embodiment 4
					Used resin	?PP	?PP	?PP	Polyamide
Spinnability	Excellent	Very	Excellent	Excellent
					Powder content % in the fiber	?2	?10	?4	?4
