Description

Core-shell structure material with retained active ingredients and preparation method thereof Technical Field The invention relates to a core-shell structure material, in particular to a core-shell structure material which is used for textile yarns and retains active ingredients and a preparation method thereof. Background Conventionally, in the production of functional yarn, a porous material containing an active ingredient such as an organic substance is usually added to a raw material for forming yarn, and the spun yarn is given a predetermined functionality. However, since the organic active ingredient is usually an organic compound having a relatively low molecular weight and relatively poor heat resistance, the organic active ingredient is likely to volatilize or even decompose when the environmental temperature is increased during the spinning process. Of particular concern in the current industry is that functional yarns are produced by a polyester or nylon melt spinning process at high temperatures above 260 ℃, but at these high temperatures the organic components are lost during the production process. At present, the common practice is to use the raw material containing the porous material to keep the active ingredients of the organic matters in the raw material containing the porous material, and then reduce the loss of the active ingredients of the organic matters in the subsequent process through the adsorption of the active ingredients of the organic matters by the nano-scale pores in the porous material. However, the method of retaining the active ingredients of the organic matters only by the adsorption of the nano-scale holes in the raw materials has no substantial improvement effect on the high-temperature spinning process, and the active ingredients of the organic matters still volatilize and dissipate continuously in the high-temperature environment. Therefore, how to produce functional yarns by the conventional spinning process and to retain the active ingredients of various organic substances imparting functionality to the yarns has been one of the subjects of research and innovation in the textile technology field. One of the prior related art is published patent application TW201350150A, which discloses the use of a single component in a fiber, fabric or cloth, and three ways to bind the active component of the organic matter to the yarn. The first way is to grind a piece of plant directly into micro powder of 26 μm to 60 μm with a nanometer micronizer, and then uniformly mix the piece of plant into a base material selected from polypropylene or any textile raw material. Taking polypropylene as an example, the base material mixed with one piece of micro powder is pumped into polypropylene fiber containing one piece of root at the temperature of 160-180 ℃, or further made into cloth containing one piece of root. The second method is to mix a root micro powder into a gel to obtain a granular root gel, and then adsorb the root gel on a fiber cloth at a temperature of 100 ℃ to 120 ℃. The third method is that the whole plant is crushed into powder by a crusher, then is extracted by 10 times of volume of 70% alcohol solution, the extract is collected and filtered by filter paper in an air extraction way, and then the extract is concentrated under reduced pressure to remove the solvent, thus obtaining a root extract. Then, the extract of one root is adsorbed by the adsorbents such as active carbon, diatomite, beta-cyclodextrin and the like in different modes to obtain the nano porous medium for adsorbing one root. Finally, the nano porous medium absorbing one root extract is subjected to the yarn drawing procedure or the absorption procedure. More specifically, when activated carbon is used for adsorption treatment, activated carbon is added to an alcohol extract containing one root extract, and the mixture is stirred for 6 hours to allow the activated carbon to adsorb one root extract, and then the mixture is filtered and freeze-dried to obtain the activated carbon adsorbing one root extract. When diatomite or beta-cyclodextrin is used for adsorption treatment, diatomite and beta-cyclodextrin are respectively added into two alcohol extracts containing one root extract, and stirred for 12 hours to enable the diatomite and the beta-cyclodextrin to adsorb one root extract respectively, and then the diatomite adsorbing one root extract and the beta-cyclodextrin adsorbing one root extract are obtained through filtration and freeze drying. In the textile technology field, the published patent application TW200425946A discloses a composition of nano-micron coated particles and preparation thereof, and the technical disclosure includes using a sol-gel method to make inorganic colloid as a dense or porous coating layer and coating liquid or solid microparticles formed by organic substances, thereby improving physical properties, chemical resistance and heat resistance of materials.
