Abstract
The invention discloses a renewable environment-friendly fabric and a preparation method thereof, wherein the preparation method of the renewable environment-friendly fabric comprises the following steps: renewable fabrics (modified viscose fibers, tencel and modal fibers) are selected as raw materials, and then coiling, cotton carding, blending and vortex spinning are carried out. In order to solve the defects of poor moisture absorption, large shrinkage rate and hard hand feeling of viscose, tencel with good moisture absorption, comfortableness and drapability, modal with luster, softness, dyeability and moisture absorption and modified viscose are compounded, and the prepared fabric has good moisture absorption and soft and comfortable touch feeling. The modified viscose fiber is graphene modified viscose fiber, so that the viscose fiber has antibacterial capacity and moisture-conducting and quick-drying capacity.
Description
Technical Field
The invention relates to the technical field of composite regenerated cellulose fiber fabrics, and particularly relates to a renewable environment-friendly fabric and a preparation method thereof.
Background
At present, textile fiber raw materials mainly comprise natural fiber raw materials represented by cotton, hemp and the like, petroleum-based fiber raw materials represented by terylene, acrylic fibers and the like, and bio-based fiber raw materials such as viscose fiber and the like regenerated by natural cellulose materials. At present, with the scarcity of land resources and the shortage of human resources, the cotton planting area is in a descending trend year by year, and cotton products cannot meet the increasing requirements of the living standard of people; with the gradual decrease of petroleum reserves and the continuous enhancement of people's consciousness on comfort, functionality and environmental protection of textiles, viscose fibers produced by using renewable resources as raw materials are more and more paid attention.
The regenerated cellulose fiber raw material is derived from natural fiber, the chemical structure of the fiber is kept unchanged, and the physical structure is only changed, and the regenerated cellulose fiber raw material mainly comprises viscose fiber (Rayon), modal, tencel (conifer is taken as a main raw material), bamboo fiber (moso bamboo is taken as a main raw material), cuprammonium fiber and acetate fiber. However, the strength of the single viscose fiber is obviously reduced after moisture absorption, the shrinkage rate is large, the fabric has hard hand feeling and poor dimensional stability, and the further development of the single viscose fiber is seriously hindered.
Disclosure of Invention
In order to overcome the defects of the prior art, one of the purposes of the invention is to provide a preparation method of a renewable environment-friendly fabric, wherein modified viscose, tencel and modal are selected as raw materials to be mixed and then are subjected to vortex spinning, so that the problems of obvious strength reduction, large shrinkage and hard fabric hand feeling after the viscose absorbs moisture can be solved; the second purpose of the invention is to provide a renewable environment-friendly fabric which is comfortable in hand feeling and good in moisture absorption capacity, and has the functions of resisting and inhibiting bacteria, and conducting moisture and quickly drying due to the addition of graphene into the modified viscose fiber.
One of the purposes of the invention is realized by adopting the following technical scheme:
a preparation method of a renewable environment-friendly fabric comprises the following steps:
1) selecting modified viscose fiber, tencel and modal as raw materials; wherein the modified viscose fiber is graphene modified viscose fiber;
2) coiling the raw materials in the step 1) by a combined opening and picking machine;
3) carding the coiled raw materials in the step 2) respectively;
4) mixing the raw materials after cotton carding;
5) and carrying out vortex spinning on the blended raw materials to obtain the renewable environment-friendly fabric.
Further, the preparation method of the modified viscose fiber comprises the following steps:
1) dissolving graphene in water to prepare a graphene dispersion liquid, adding viscose, and then grinding;
2) grinding, adding the phase-change microcapsule emulsion to obtain a spinning solution, uniformly stirring, and standing for defoaming;
3) and filtering the defoamed spinning solution, pumping the filtered spinning solution into a spinneret plate, spraying tows from the spinneret plate, solidifying the tows in a coagulating bath to form primary filaments, and drafting and post-processing the primary filaments to obtain the modified viscose fiber.
Further, adding an antibacterial component into the spinning solution, wherein the antibacterial component is fennel extract and/or litsea cubeba extract; wherein the antibacterial component accounts for 2-5 wt% of the mass of the viscose spinning solution.
Further, the graphene accounts for 0.5-1 wt% of the mass of the viscose spinning solution, and the phase-change microcapsule emulsion accounts for 3-5 wt% of the mass of the viscose spinning solution.
Still further, the preparation method of the phase-change microcapsule emulsion comprises the following steps:
