Use of textured thread material in textile planar structures for use as pollen filter

Abstract

The use of textile fabrics which contain at least one textured thread for attachment in front of windows or doors to protect against dusty allergens such as pollen or house dust.

1 . The use of textile fabrics which contain at least one textured thread for attachment in front of windows or doors to guard against dusty allergens such as pollen or house dust.  
     
     
         2 . The use according to  claim 1 , wherein the fabric is a formed-loop knit having a basis weight between 30 and 200 g/m 2  and preferably between 40 and 70 g/m 2 .  
     
     
         3 . The use according to claims  1  or  2 , wherein the filaments of the threads consist of polyesters, polyamides or polyolefins.  
     
     
         4 . The use according to at least one of  claims 1  to  3 , wherein the diameter of the filaments of the threads is between 1 and 100 μm, preferably between 1 and 50 μm and more preferably between 1 and 25 μm.  
     
     
         5 . The use according to at least one of  claims 1  to  4 , wherein the diameter of the threads is between 50 and 500 μm and preferably between 50 and 250 μm.  
     
     
         6 . The use according to at least one of  claims 1  to  5 , wherein the warp threads of the formed-loop knit are lapped as a straight pillar stitch with a DIN 53883 wale density from 20 to 500 and preferably from 30 to 70 and a DIN 53883 course density from 20 to 600, preferably from 50 to 300 and more preferably from 100 to 250.  
     
     
         7 . The use according to at least one of  claims 1  to  6 , wherein at least one textured fill thread is inlaid in the pillar stitch lappings.  
     
     
         8 . The use according to at least one of  claims 1  to  7 , wherein the textured fill thread has a linear density from 5 to 30 tex and preferably from 5 to 15 tex.  
     
     
         9 . The use according to at least one  claims 1  to  8 , wherein at least one fill thread is inlaid in the pillar stitch lappings.  
     
     
         10 . The use according to at least one of  claims 1  to  9 , wherein the distance between fill threads is between 0 and 1 mm and preferably between 20 and 200 μm.  
     
     
         11 . The use according to at least one of  claims 1  to  10 , wherein at least one fill thread in particular insertion joins adjacent or nonadjacent pillar stitch lappings together in a zigzag shape by joining two adjacent courses of the pillar stitches together.  
     
     
         12 . A fly screen comprising a textile fabric according to any one of  claims 1  to  11 .
