Problems solved by technology

If the dispersion effect of graphene is not good, it will block the spinneret of high-speed spinning, resulting in spinning failure
2. The small lateral size of graphene is good for dispersion, but the far-infrared effect is not good; the large lateral size of graphene will increase the difficulty of graphene dispersion in nylon 6
3. The small carbon-oxygen ratio of graphene is helpful for dispersion, but the far-infrared effect of graphene with high oxygen content is poor; increasing the carbon-oxygen ratio of graphene also increases the difficulty of graphene dispersion in nylon 6
Carbon 95 (2015) 625-633 reported that graphene was introduced into fabrics to obtain far-infrared functions by fabric surface coating. Environmental Pollution
This type of far-infrared functional fabric will have a very limited service life due to washing and wear, which not only reduces the cost performance of the product, but also causes waste of resources and environmental pollution due to the elimination of expired products.

Abstract

The invention relates to a graphene / nylon-6 fabric with a permanent far-infrared healthcare function and a preparation method thereof and belongs to the field of functional fabrics. The graphene / nylon-6 fabric with the permanent far-infrared healthcare function is formed by texturizing graphene / nylon-6 compound material fabric, which is obtained through in-situ polymerization and melt spinning of modified graphene and caprolactam. The graphene / nylon-6 fabric with the permanent far-infrared healthcare function obtains excellent physical and mechanical performance as well as functions no available in various nylon-6 fabrics, particularly, the far-infrared healthcare function, which is permanent in effect and cannot be weakened by repeated washing of the fabric. The far-infrared emission rate of the graphene / nylon-6 fabric is higher than 0.88 and can meet the requirements of standard GB / T130127-2013 on far-infrared performance of fabric, accordingly, the graphene / nylon-6 fabric with the permanent far-infrared healthcare function can be applied to the fields of underwear, blankets, beddings, tents and the like.

Description

technical field [0001] The invention relates to a graphene / nylon 6 fabric with permanent far-infrared health care function and a preparation method thereof, belonging to the technical field of functional fabrics. Background technique [0002] Nylon 6 (also known as nylon 6) fabric has excellent properties such as high strength, wear resistance, good resilience, moth resistance, and corrosion resistance. It is widely used in various clothing materials, masking materials and knitwear. Nylon 6 fabric is a light fabric, very suitable for high-end mountaineering clothing, winter clothing and swimwear. [0003] Far-infrared is the part of the spectrum with a wavelength of 8-15 microns, which is an essential factor for biological survival, also known as "life light wave". Far-infrared can produce the most effective "resonance" with the water molecules of the cells in the living body, and at the same time have the permeability, which can effectively promote the growth of animals an...
