Netting material

Abstract

An agricultural netting material has a construction profile across the width of the netting in which one or more construction elements varies across the width of the netting, a construction element in a first region of at least 20 cm width of the netting being different to the construction element in a second region of at least 20 cm width of the netting, the construction element being one of a yarn thickness, a yarn width, a yarn transmittance, a yarn pigmentation, a yarn reflectance, a yarn absorbance, a netting aperture size, a netting construction pattern and a netting cover factor.

1 . A knitted netting material:
 comprising pillars knitted in a length direction and held together with yarns that cross back and forth between the pillars in a width direction defining netting apertures,   having a width dimension of at least two metres and a greater length dimension, having an aperture size that varies across the width of the netting, and comprising a first region of the netting material comprising a first aperture size, a second region of the netting comprising a second aperture size, and a third region of the netting comprising a third aperture size,   wherein the first aperture size is larger than the second aperture size and the second aperture size is larger than the third aperture size,   wherein the first region is a central region of the netting, and the third region is a peripheral region of the netting either side of the central region, and the second region is an intermediate transition region of the netting located either side of the central region and between the central region and each peripheral region.   
     
     
         2 . A netting material as claimed in  claim 1 , wherein edge portions of the netting are reinforced or formed with different material. 
     
     
         3 . A netting material as claimed in  claim 1 , wherein the width of the central first region comprises 60% or more of the width of the netting material. 
     
     
         4 . A netting material as claimed in  claim 2 , wherein the width of the central first region comprises 60% or more of the width of the netting material. 
     
     
         5 . A netting material as claimed in  claim 1 , wherein a spacing between adjacent pillars in the first region is larger than a spacing between adjacent pillars in the second region, and the spacing between adjacent pillars in the second region is larger than a spacing between adjacent pillars in the third region. 
     
     
         6 . A netting material as claimed in  claim 2 , wherein a spacing between adjacent pillars in the first region is larger than a spacing between adjacent pillars in the second region, and the spacing between adjacent pillars in the second region is larger than a spacing between adjacent pillars in the third region. 
     
     
         7 . A netting material as claimed in  claim 3 , wherein a spacing between adjacent pillars in the first region is larger than a spacing between adjacent pillars in the second region, and the spacing between adjacent pillars in the second region is larger than a spacing between adjacent pillars in the third region. 
     
     
         8 . A netting material as claimed in  claim 5 , wherein the second region has a tighter knit than the first region and the third region has a tighter knit than the second region. 
     
     
         9 . A netting material as claimed in  claim 6 , wherein the second region has a tighter knit than the first region and the third region has a tighter knit than the second region. 
     
     
         10 . A netting material as claimed in  claim 7 , wherein the second region has a tighter knit than the first region and the third region has a tighter knit than the second region. 
     
     
         11 . A netting material as claimed in any one of  claim 1 , wherein the first region has a width between 200 mm and 3 metres. 
     
     
         12 . A netting material as claimed in  claim 1 , wherein the first region of the netting material comprises an aperture size of about 7 mm, and the second region of the netting material comprises an aperture size of about 6 mm, and the third region of the netting material comprises an aperture size of about 5 mm. 
     
     
         13 . A netting material as claimed in  claim 11 , wherein the first region of the netting material comprises an aperture size of about 7 mm, and the second region of the netting material comprises an aperture size of about 6 mm, and the third region of the netting material comprises an aperture size of about 5 mm.
