Abstract

The present invention of a manufacturing process of a Teflon dual-direction extending film filtration nonwoven uses a Teflon, after it is splitted and become a fibrous structure, followed by inter-twisting to become yarn, and use a knitting machine to knit as a Teflon fabric, after raising to damage its knots, apply thermo-heating to laminate and adhere-combine the Teflon dual-direction extending film, a filtration nonwoven is made, roll the filtration nonwoven with two sides treated by raising repeatedly to become a filtration material or as a filter bag, a dust-collecting bag or a conveyor, thus a Teflon fabric has the characteristics of having stably fixed position and can optimize its filtration effectiveness.

Claims

exact text as granted — not AI-modified
1 . The present invention of manufacturing process of a Teflon dual-direction extending film filtration nonwoven having the following procedures; 
 a Teflon dual-direction extending film is splitted;    said film is inter-twisted to become yarn;    said yarn is knitted as a Teflon fabric by a knitting machine;    said Teflon fabric has to go through raising treatment;    on one or two sides of said Teflon fabric, apply thermo-heating to laminate and adhere-combine said Teflon dual direction extending film;    thus a filtration nonwoven is made accordingly.    
   
   
       2 . The present invention of manufacturing process of a Teflon dual-direction extending film filtration nonwoven as claimed in  claim 1 , said filtration nonwoven is rolled to become a filtration material.  
   
   
       3 . The present invention of manufacturing process of a Teflon dual-direction extending film filtration nonwoven as claimed in  claim 1 , a plurality of said filtration nonwoven can be connected to become a conveyor.  
   
   
       4 . The present invention of manufacturing process of a Teflon dual-direction extending film filtration nonwoven as claimed in  claim 1 , said filtration nonwoven can be processed to become a filtration bag.  
   
   
       5 . The present invention of manufacturing process of a Teflon dual-direction extending film filtration nonwoven as claimed in  claim 1 , said filtration nonwoven can be processed to become a dust-collection bag.
