Abstract

A high-strength, heat-resistant organic fiber and textile product each comprising or having coated thereon an aqueous emulsion is provided. The emulsion comprises or is produced from a fluorocarbon silane or an emulsion, said emulsion comprises or is produced from (1) a fluorocarbon silane or its hydrolyzate, (2) water, and (3) optionally a surfactant, an alkoxysilane compound, catalyst, or combinations of two or more thereof; said fluorocarbon silane having the formula R f —(CH 2 ) p —Si{—(O—CH 2 CH 2 ) n —OR 1 } 3 ; R f is a C 3-18 perfluoroalkyl group or combinations of two or more thereof; each R 1 is independently one or more C 1-3 alkyl groups; p is 2 to 4; and n is 2 to 10. Also disclosed is a process for producing the emulsion, the fiber, and the textile product.

Claims

What is claimed is:  
     
         1 . A composition comprising a fiber which comprises or has coated thereon a thin film wherein said thin film comprises or is produced from a fluorocarbon silane or an emulsion, said emulsion comprises or is produced from (1) a fluorocarbon silane or its hydrolyzate, (2) water, and (3) optionally a surfactant, an alkoxysilane compound, a catalyst, or combinations of two or more thereof; said fluorocarbon silane has the formula R f —(CH 2 ) p —Si{—(O—CH 2 CH 2 ) n —OR 1 } 3 ; R f  is a C 3-18  perfluoroalkyl group or combinations of two or more thereof; each R 1  is independently one or more C 1-3  alkyl groups; p is 2 to 4; and n is 2 to 10.  
     
     
         2 . The composition of  claim 1  wherein said thin film further comprises, or is further produced from, a copolycondensate of said fluorocarbon silane and an alkoxysilane.  
     
     
         3 . The composition of  claim 1  wherein said thin film has a thickness of less than 1,000 nm.  
     
     
         4 . The composition of  claim 2  wherein said thin film has a thickness of less than 1,000 nm.  
     
     
         5 . The composition of  claim 1  wherein said fiber is an aromatic polyamide fiber, an aromatic polyester fiber, a heterocyclic aromatic fiber, or combinations of two or more thereof.  
     
     
         6 . The composition of  claim 2  wherein said fiber is an aromatic polyamide fiber, an aromatic polyester fiber, a heterocyclic aromatic fiber, or combinations of two or more thereof.  
     
     
         7 . The composition of  claim 3  wherein said fiber is an aromatic polyamide fiber, an aromatic polyester fiber, a heterocyclic aromatic fiber, or combinations of two or more thereof.  
     
     
         8 . The composition of  claim 4  wherein said fiber is an aromatic polyamide fiber, an aromatic polyester fiber, a heterocyclic aromatic fiber, or combinations of two or more thereof.  
     
     
         9 . The composition of  claim 5  wherein said fiber is a p-phenylene terephthalamide fiber.  
     
     
         10 . The composition of  claim 6  wherein said fiber is a p-phenylene terephthalamide fiber.  
     
     
         11 . The composition of  claim 7  wherein said fiber is a p-phenylene terephthalamide fiber.  
     
     
         12 . The composition of  claim 8  wherein said fiber is a p-phenylene terephthalamide fiber.  
     
     
         13 . A textile product comprising or produced from a fiber having coated thereon an emulsion, which comprises or is produced from (1) a fluorocarbon silane or its hydrolyzate, (2) water, and (3) optionally a surfactant, an alkoxysilane compound, a catalyst, or combinations of two or more thereof.  
     
     
         14 . The product of  claim 13  wherein said product is a woven product, a knit product, a nonwoven fabric, or combinations of two or more thereof.  
     
     
         15 . The product of  claim 14  wherein said product is a woven fabric for protective clothing.  
     
     
         16 . The product of  claim 14  wherein said product is a firefighting apparel.

         18 . A process comprising combining a fluorocarbon silane or its hydrolyzate, water, and optionally a surfactant, an alkoxysilane compound, a catalyst, or combinations of two or more thereof to produce a mixture and optionally heating said mixture to produce an emulsion wherein said fluorocarbon silane having the formula R f —(CH 2 ) p —Si{—(O—CH 2 CH 2 ) n —OR 1 } 3 ; R f  is a C 3-18  perfluoroalkyl group or combinations of two or more thereof; each R 1  is independently one or more C 1-3  alkyl groups; p is 2 to 4; and n is 2 to 10.  
     
     
         19 . The process of  claim 18  further comprising producing a thin film of said emulsion onto a fiber wherein said thin film has a thickness of less than 1000 nm.  
     
     
         20 . The process of  claim 19  wherein said thin film further comprises, or is further produced from, a copolycondensate of said fluorocarbon silane and an alkoxysilane.
