Antimicrobial polyamide 6 fibre and production method thereof

Abstract

The invention relates to antibiosis polyamide-6 fiber and the manufacturing method. The antibiosis inorganic material with the grain diameter of 0.4 to 0.8 Mu, the coupling agent, the anti oxidant, and the surface active agent are added into a steam flow membrane mixer to perform the dry process surface treatment, the superfine material powder body after surface treatment is mixed with the polyamide-6 carrier inside a high speed mixer, the obtained mixed powder material is sent into a double screw arbor extruder to make the blending extrusion, the working temperature is 20 to 30 DEG C lower than the temperature for conventional manufacturing nylon 6 agglomerate, which ensures that the degradation of the raw material carrier and the oxidation of the silver ion are not occurred, the above obtained antibiosis agglomerate and the polyamide-6 sliced sheet are metered and mixed through a measuring filling machine, and then sent to the anti bacterial fiber screw spinning machine to perform the spinning. The anti bacterial ratio of the invention can reach 99 percent, the using is secure, and stimulation free to the skin, the invention can be widely utilized on the textile which is directly contacted with the skin such as underclothes, shirts, swimsuits, and socks.

Description

technical field [0001] The invention relates to an antibacterial fiber and a manufacturing method thereof, in particular to an antibacterial polyamide 6 fiber made by adding antibacterial masterbatches and a manufacturing method thereof. Background technique [0002] The processing of antibacterial fibers and fabrics mainly adopts the following two methods: post-finishing method and fiber modification method. The post-finishing method accounts for 70% of the antibacterial of processed fibers, mainly organic antibacterial agents, such as quaternary ammonium salt antibacterial agents, but due to This method is to attach the antibacterial active ingredient to the surface of the fiber, and the antibacterial product obtained is not resistant to washing, has poor durability, and is prone to drug resistance. At the same time, this method has poor heat resistance, has certain toxicity and volatility, and is prone to residues. In the late 1980s, the production of antibacterial fibers...

AI Technical Summary

Problems solved by technology

The main manifestations are: nano silver ions are easy to oxidize and yellow and cause discoloration of nylon 6 fibers; if the particle size of the antibacterial powder is too large or the dispersion is not good, it is easy to cause filter blockage and spinneret holes in the spinning process Blockage, causing yarn drifting, end breakage and component pressure to rise rapidly, or even normal production; nano-scale antibacterial powder is very easy to agglomerate in the process of manufacturing antibacterial masterbatch and spinning, and become coarse particles to block the filter screen and spinneret holes ;The addition of inorganic particles changes the surface friction properties of the fiber, and the fiber is prone to hairiness during the production process, which causes the physical index of the fiber to decline, so that it cannot meet the requirements of subsequent processing.
