Method for manufacturing nano size-clay containing polypropylene fiber using Nylon 6 and anhydride maleic polypropylene as compatibilizer, and nano size-clay containing polypropylene fiber manufactured by the method
Method for manufacturing nano size-clay containing polypropylene fiber using Nylon 6 and anhydride maleic polypropylene as compatibilizer, and nano size-clay containing polypropylene fiber manufactured by the method
Nanoparticle type clay containing polypropylene fiber and a method for manufacturing the same are provided to improve the dispersibility of clay in polypropylene and optimize the ratio of nylon 6 over clay and the ratio of polypropylene over a master batch, thereby improving dispersibility, fire retardant property, and impact-resistance of the fiber, by forming the master batch of clay and nylon-6 and mixing polypropylene into the master batch. A nylon 6/clay nano-organic composite master batch is prepared by stirring materials where 15-20 wt% of organic clay is added into nylon 6, at a temperature of 80°C, and melting the stirred materials using a two-axes extruding machine. A nano-organic composite pallet for a polypropylene/anhydride maleic propylene/nylon 6/clay fiber is prepared by adding 20-40 wt% of anhydride maleic propylene and 60-80 wt% of pure polypropylene into the master batch and melting the added materials using the two-axes extruding machine, wherein the nano-organic composite pallet contains 3-5 wt% of montmorillonite. The prepared pallet is dried in a rotary type vacuum oven for 6 hours. The dried pallet is spun to manufacture a nano composite fiber. A nano composite staple fiber is manufactured by winding and cutting the nano composite fiber. A weight rate of polypropylene : nylon 6 : clay is 75-82 : 15-20 : 3-5.
