Membrane curtain barrier with hemmed pocket attached by interlock stitching

Abstract

A curtain barrier with an attached hem pocket using an interlocking stitch techniqueis disclosed. The agricultural membrane curtain comprises a curtain body made of a non-porous fabric material and one or more breathable hem pockets extending along the bottom edge of the curtain body. The hem pocket is sewn to the curtain body using a plurality of intersecting sew lines creating an interlocking stitch pattern to avoid unraveling due to thread damage. The sew lines may comprise thread, yarn, or filament and the interlocking stitch pattern forms multiple stop points for automatic sealing in the event of deterioration of one or more stitches.

1 . A curtain barrier comprising:
 at least one breathable hem pocket attached to a horizontal bottom edge of a curtain body using at least two sew lines, wherein the sew lines comprise a series of interlocking sections with equal spacing between each interlocking section.   
     
     
         2 . The curtain barrier of  claim 1 , wherein the series of interlocking sections of the sew lines comprise a cross-stitch pattern. 
     
     
         3 . The curtain barrier of  claim 1 , wherein the series of interlocking sections comprise alternating diagonal sew lines, with one-inch spacing between an end or peak of each diagonal sew line. 
     
     
         4 . The curtain barrier of  claim 1 , wherein the series of interlocking sections comprise alternating arched or curved sew lines, with one-inch spacing between the intersection of each sew line. 
     
     
         5 . The curtain barrier of  claim 1 , wherein the series of interlocking sections comprise alternating diagonal sew lines, with sections of parallel sew lines alternating with opposite diagonal sew lines, with one-inch spacing between the intersections of each set of diagonal lines. 
     
     
         6 . The curtain barrier of  claim 1 , wherein the sew lines intersect with each other to create sealing stop points for the cessation of unraveling of sew lines in the event of sew line fault. 
     
     
         7 . The curtain barrier of  claim 1 , wherein the length between the sew line intersections or the peaks of diagonal sew lines are indicative of a measuring system. 
     
     
         8 . The curtain barrier of  claim 1 , whereinthe breathable hem pocket includes a break-proof or self-securing stitch. 
     
     
         9 . The curtain barrier of  claim 1 ,comprisesa curtain for use as an agricultural membrane curtain, livestock membrane curtainor industrial ventilation membrane curtain. 
     
     
         10 . A method of sewing a hem pocket onto a curtain barrier, the method comprising:
 bringing together a curtain body and a hem pocket for stitching;   sewing the hem pocket along abottom edge of the curtain body using at least two sew lines;   creating a cross-stitch pattern by intersecting at least two sew lines along the bottom edge of the curtain body.   
     
     
         11 . The method of  claim 10 , wherein the hem pockets are made of a non-porous fabric material. 
     
     
         12 . The method of  claim 10 , wherein the cross-stitch pattern comprisesa series of interlocking diagonal sew lines, with one-inch spacing between an end or peak of each diagonal line. 
     
     
         13 . The method of  claim 10 , wherein the cross-stitch pattern comprisesa series of interlocking arched or curved sew lines, with one-inch spacing between an end or peak of each curved sew line. 
     
     
         14 . The method of  claim 10 , wherein the cross-stitch pattern comprises a series of interlocking diagonal sew lines with sections of parallel sew lines alternating with opposite diagonal sew lines, with one-inch spacing between an end or peak of each diagonal sew line. 
     
     
         15 . The method of  claim 10 , wherein the cross-stitch pattern comprisesa plurality of sealing stop-points created by the intersecting sew lines for the cessation of unraveling sew lines in the event of sew line fault. 
     
     
         16 . The method of  claim 10 , wherein the cross-stitch pattern is created using three sew lines.
