         wherein M is an H atom, alkyl, Alkoxy group, hydroxyl, Hydroxyalkyl group or carbonyl; and 2≤n≤16. 
       
     
     
         4 . The water-repellent textile according to  claim 1 , wherein the non-fluorinated water-repellent compound is a hydrocarbon compound, a polysiloxane compound A or a copolymer thereof. 
     
     
         5 . The water-repellent textile according to  claim 4 , wherein the hydrocarbon compound is an acrylate compound having a structural unit shown in formula 2, 
       
         
           
           
               
               
           
         
         wherein R 1  and R 2  are alkyl or unsaturated hydrocarbon groups, respectively; and 2≤n≤200. 
       
     
     
         6 . The water-repellent textile according to  claim 4 , wherein the polysiloxane compound A is a compound having a structure shown in formula 3, 
       
         
           
           
               
               
           
         
         wherein R 3 , R 4 , and R 5  are alkyl or unsaturated hydrocarbon groups, respectively. 
       
     
     
         7 . The water-repellent textile according to  claim 1 , wherein the resin film comprises a flexible compound, and the flexible compound is a polyethylene compound and/or a polysiloxane compound B. 
     
     
         8 . The water-repellent textile according to  claim 1 , wherein the resin film has a thickness of 40 to 100 nm after being washed for 100 times according to the method 103 in JIS L 0217:1995 criteria or the method C4M in JIS L 1930:2014 criteria. 
     
     
         9 . The water-repellent textile according to  claim 1 , wherein the initial water repellency of the textile is level 4 or above according to a test using the spray method in JIS L 1092:2009 criteria.
