Description
Technical field
The present invention relates to a kind of preparation method of thermo-regulated fiber.
Background technology
Thermo-regulated fiber is a kind of tencel with Double-direction Temperature regulating action.It can absorb heat and be stored in fibrous inside, or emit the heat of storing in fiber according to the variation of ambient temperature from environment, the substantially invariable micro climate of formation temperature around fiber, thus realize temp regulating function.This heat absorption and release process of thermo-regulated fiber is automatic, reversible, unlimited.
It is different that thermo-regulated fiber and the difference of traditional fibre are to be incubated mechanism.Traditional fiber thermal insulation is mainly to avoid skin temperature to reduce too much by insulation method, and insulation effect depends primarily on thickness and the density of fabric.The insulation of thermo-regulated fiber is by the sensitivity response to moisture and ambient pressure variation, for human body provides comfortable moist heat, provides thermal conditioning rather than thermal isolation, is therefore a kind of brand-new insulation mechanism.
Chinese patent CN102535172A discloses a kind of heat storing heat preserving finishing agent, and the adhesion of itself and fabric fibre is poor, and after washing repeatedly, heat-accumulating and-keeping effect obviously descends.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of thermo-regulated fiber, the above-mentioned defect existed to overcome prior art.
For solving the problems of the technologies described above, the invention provides a kind of preparation method of thermo-regulated fiber, comprise the steps:
1) heat-accumulation temperature-adjustment master batch preparation: by heat-accumulation temperature-adjustment agent and polyethylene blending, drying, enter the extruser melt blending and extrude, granulation, obtain the heat-accumulation temperature-adjustment master batch;
2) thermo-regulated fiber production: by after heat-accumulation temperature-adjustment master batch and fibre section blend, after spinning, coiling, stretching, form thermo-regulated fiber;
Described heat-accumulation temperature-adjustment agent is comprised of the component of following weight portion:
The preferred 30-75 nanometer of described molybdenum oxide particle diameter, the preferred 20-80 nanometer of described titanium dioxide particle diameter.
Described Sodium Polyacrylate dispersant preferred viscosities 300-350mPas.
In the heat-accumulation temperature-adjustment master batch, the heat-accumulation temperature-adjustment agent content is 5～20wt%.
Heat-accumulation temperature-adjustment master batch and fibre section 1:10～20 in mass ratio mix.
The thermo-regulated fiber production technology is identical with the conventional fibre production technology.For example, a certain proportion of heat-accumulation temperature-adjustment polyester master particle is added in polyester slice, fully mix in rotary drum dryer, drying, to reach homodisperse purpose.Process conditions and process are pressed the drying process of polyester slice and are implemented.During spinning, spinning machine winding speed 3200m/min, draw false twist texturing machine draft speed 150～800m/min; 282～288 ℃ of spinning temperatures.
The TL series aluminum zirconium ester coupling agent product that Aluminum zirconium coupling agent can adopt Chongqing Gao Yao Science and Technology Ltd. to produce.
The present invention adopts NSC 77136 and molybdenum oxide as the heat-accumulation temperature-adjustment main material, adds titanium dioxide simultaneously, utilizes it can absorb ultraviolet characteristic, but the heat accumulation usefulness of Synergistic molybdenum oxide.In addition, heat-accumulation temperature-adjustment agent of the present invention can with the fabric fibre strong bonded, durability is strong, and fabric fibre is had to good heat-accumulation temperature-adjustment effect.
