Description
Technical Field
The invention relates to the technical field of textile fabrics, in particular to a wool and graphene blended yarn and a production method of the fabric.
Background
With the improvement of living standard and the progress of textile technology, the demand of functionalization of the fabric is higher and higher. Taking a wool fabric as an example, the functional finishing of the wool fabric mainly comprises flame retardance, bacteria resistance, ultraviolet resistance, static resistance, electric conduction, heating and the like. The main mode is that special functional auxiliary agents or special functional fibers are added into the wool fabric.
Graphene is the thinnest, the hardest and the strongest novel nano material at present, and has certain research when being applied to the fields of fabrics and the like, so that the fabrics can have excellent performances of good bacteriostasis, antibiosis, ultraviolet resistance, heating and the like. Generally, the graphene fiber is obtained by melting and processing polyamide, spandex and terylene with graphene, but the components of chemical fiber are introduced during the mixed spinning of the graphene fiber and wool. Since the chemical synthetic fibers have poor adsorbability, cannot be well adsorbed to wool fibers, affect the texture and grade of the fabric, and also affect the moisture absorption and air permeability of the fabric, it is necessary to improve the method for adding the graphene functional component to the wool fabric.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a wool graphene blended yarn which has good adsorption with wool fibers and good moisture absorption and air permeability, and can endow wool fabric with a graphene function without adding chemical-based fibers, and a production method of the fabric.
In order to achieve the purpose, the technical scheme of the invention is to design a production method of a wool-graphene blended yarn, which comprises the working procedures of graphene functional silk preparation → graphene functional silk and wool top drawing → spinning → warping → sizing; the preparation process of the graphene functional silk comprises the following steps: and (3) immersing the filaments obtained by degumming the mulberry silk into a graphene oxide-ethanol solution for graphene grafting, rolling off the graphene oxide-ethanol solution in the filaments after grafting is finished, and finally, cleaning and drying to obtain the graphene functional silk. Carboxyl on the graphene oxide single sheet and amino of silk fibroin of the filament rapidly generate covalent crosslinking in an alcohol solution, so that the graphene single sheet is deposited and grafted on the surface of the filament, the filament deposited with the graphene is drawn and co-spun with wool tops to prepare wool and graphene blended yarn, and the problems of poor adsorbability of graphene-chemical-based fibers and wool fibers and unevenness of the prepared fabric are solved; meanwhile, mulberry silk is introduced into the blended yarn, so that the wool/mulberry silk/graphene blended fabric made of the blended yarn has the effects of elegant and smooth silk, smooth, glutinous and full cashmere wool hand feeling and sufficient elasticity, has the effects of antibiosis, ultraviolet resistance, heating and heat preservation of graphene, and is light and warm in weight, moisture-absorbing and breathable, and high in texture and grade.
The grafting finishing of the graphene oxide and the filament is mainly a process of combining carboxyl on a single graphene oxide sheet with amino at the end of a polypeptide chain of silk fibroin through dehydration condensation reaction, and in order to increase the grafting number of the graphene oxide sheet, the preferable technical scheme is that the preparation process of the graphene functional silk also comprises a pretreatment process, specifically, the degummed filament is firstly immersed into a hexamethylenediamine-ethanol solution for pretreatment, then the hexamethylenediamine-ethanol solution in the filament is removed through rolling, the filament is washed for 2-3 times, and finally the filament after the hexamethylenediamine pretreatment is immersed into the graphene oxide-ethanol solution for grafting the graphene.
