Light-protective textile

Abstract

The present invention relates to a textile light-protective material composed of a microfilament non-woven fabric having a mass per unit area of 20 to 300 g/m 2 , in which the non-woven fabric is made of melt-spun and drawn multicomponent continuous filaments having a titer of 1.5 to 5 dtex that are deposited immediately to form a non-woven material and at least 80% of the multicomponent continuous filaments, after an optional pre-bonding, are split to form continuous microfilaments having a titer of 0.05 to 2.0 dtex and are bonded.

       12 . A textile light-protective material comprising: 
 a microfilament non-woven fabric having a mass per unit area of 20 to 300 g/m 2 , the non-woven fabric including multicomponent continuous filaments, the filaments being melt-spun and drawn filaments having an original titer of 1.5 to 5 dtex deposited immediately to form a non-woven material;    the multicomponent continuous filaments of the non-woven material being split continuous microfilaments having a titer of 0.05 to 2.0 dtex and being bonded, a degree of splitting of the multicomponent continuous filaments being greater than 80%.    
   
   
       13 . The textile light-protective material of  claim 12  wherein the multi-component continuous filaments are pre-bonded filaments.  
   
   
       14 . The textile light-protective material as recited in  claim 12  wherein the original titer is 1.5 to 3 dtex and the titer of the split continuous microfilaments is 0.1 to 1.0 dtex.  
   
   
       15 . The textile light-protective material as recited in  claim 12  wherein the multicomponent continuous filament is a bicomponent continuous filament consisting of two incompatible polymers.  
   
   
       16 . The textile light-protective material as recited in  claim 15  wherein the two incompatible polymers are a polyester and a polyamide.  
   
   
       17 . The textile light-protective material as recited in  claim 12  wherein the multicomponent continuous filaments have a cross section of an orange-like multisegment structure, each segment in alternating fashion containing one of the two incompatible polymers and/or possessing a “side-by-side” structure.  
   
   
       18 . The textile light-protective material as recited in  claim 12  wherein the multicomponent continuous filament includes at least two incompatible polymers, and wherein at least one of the incompatible polymers contains an additive in quantities up to 10% wt.  
   
   
       19 . The textile light-protective material as recited in  claim 18  wherein the additive is at least one of a coloring pigment, a permanently acting antistatic agent, and a hydrophilic or hydrophobic-altering agent.  
   
   
       20 . A method for manufacturing a textile light-protective material having a microfilament non-woven fabric with a mass per unit area of 20 to 300 g/m 2 , comprising the steps of: 
 spinning and drawing a melted mass to form multicomponent continuous filaments having a titer of 1.5 to 5 dtex;    depositing immediately the multicomponent continuous filaments to form a non-woven material; and    bonding the non-woven material using high-pressure fluid jets and simultaneously splitting the multicomponent continuous filaments into continuous microfilaments having a titer of 0.05 to 2.0 dtex, a degree of splitting of the multicomponent continuous filaments being greater than 80%.    
   
   
       21 . The method as recited in  claim 20  wherein the non-woven material is pre-bonded before the bonding and step.  
   
   
       22 . The method as recited in  claim 20  wherein bonding step includes subjecting two sides of the non-woven material to the high-pressure fluid jets.  
   
   
       23 . The method as recited in  claim 20  further comprising spin dyeing the multicomponent continuous filaments.  
   
   
       24 . The method as recited in  claim 20  further comprising point-calendering the textile light-protective material.  
   
   
       25 . The method as recited in  claim 20  further comprising manufacturing a curtain, drape, or rolling blind from the light-protective material.  
   
   
       26 . The method as recited in  claim 20  further comprising manufacturing a vertical jalousie or a pleated blind from the light-protective material.  
   
   
       27 . The textile light-protective material as recited in  claim 12  wherein the material is part of a curtain, drape, or rolling blind.  
   
   
       28 . The textile light-protective material as recited in  claim 12  wherein the material is part of a vertical jalousie or a pleated blind.
