Abstract
The present invention discloses a graphene temperature-sensing and color-changing masterbatch for polyamide fibers, and a preparation method thereof, wherein the raw materials comprise graphene, polyamide, a dispersant, a wetting agent, temperature-sensing and color-changing powder, a thickener, polycarbonate, hexamethyldisiloxane and polyethylene glycol. The preparation method comprises: mixing graphene, a wetting agent, a thickener and polycarbonate, heating, adding hexamethyldisiloxane and polyethylene glycol, carrying out mixing grinding on the obtained mixture and temperature-sensing and color-changing powder, mixing the obtained grinded material, polyamide and a dispersant, mixing, and carrying out extrusiongranulation on the mixed material to obtain the graphene temperature-sensing and color-changing masterbatch for polyamide fibers. According to the present invention, the color masterbatch having the temperature-sensing and color-changing effect is prepared by combining the graphene used as the temperature-sensing and color-changing powder carrier, the polycarbonate and the polyamide, such that the temperature-sensing and color-changing material can be added during the polyamide fiberspinning process so as to increase the dispersity of the temperature-sensing and color-changing material in the polyamide fibers and so as not to affect the subsequent finishing on the textile.
Description
Technical field [0001] The invention belongs to the technical field of synthetic fibers, and particularly relates to a graphene thermochromic masterbatch for polyamide fibers and a preparation method thereof. Background technique [0002] Polyamide is commonly known as Nylon, English name Polyamide (PA), density 1.15g / cm 3 , Is the general term for thermoplastic resins containing repeating amide groups—[NHCO]— on the molecular backbone, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application, and its name is determined by the specific carbon number of the synthetic monomer. [0003] Polyamide is mainly used for synthetic fibers. Its most prominent advantage is that its abrasion resistance is higher than all other fibers, 10 times higher than cotton, 20 times higher than wool, and a little polyamide fiber is added to the blended fabric. Greatly improve its wear resistance; when stretched to 3-6%, ...
