Abstract: A fabric roll up core for carrying rolls of sheet material such as ground covers or canopy sheet materials including netting materials, used in agriculture or horticulture, such as bird, insect, hail, shade, wind barrier netting materials, comprises a profile formed in an outer surface that assists in maintaining the sheet material on the fabric roll up core when rolling the sheet material onto the fabric roll up core and which may be effective to work with roll up drive means. The core may be formed in one piece or as multiple connected parts.

Abstract: A woven sheet crop material comprising a woven region and a smaller knitted region. The woven region comprises a main body of the material and the knitted region is affixed to the woven region to provide an affixment region for attachment of fixing means, such as C clips or carbine clips.

Abstract: Described is a reflective ground cover sheet material (1) in which longitudinally extending opposite side margins (A) of the sheet material are stronger than a longitudinally extending center section between the side margins of the material. Also described is a reflective ground cover sheet material (1) having longitudinally extending opposite side margins (A) of the sheet material of lower porosity than a longitudinally extending center section between the side margins of the material.

Abstract: Crop protection netting for covering trees or other plants for insect or bird exclusion is of a knitted mesh construction, including knit intersections in the netting and connecting yarn portions between the yarn intersections which extend substantially linearly between intersections. The netting is lightweight and stretchable in multiple directions.

Abstract: A ground cover sheet material for use in agriculture is woven from warp and weft tapes of a plastics material and at least one warp tape comprising a wicking material to form a longitudinal wick in the sheet material through which water or vapour may flow or flow more freely than through the plastics material.

Abstract: A netting material comprises a main portion and a netted window portion. The main portion has apertures of a first aperture size and shape, and the netted window portion has apertures of a second aperture size and shape. The apertures of the netted window portion are of sufficient size and shape to allow honey bees to pass through the netting material, whereas the apertures of the main portion are of sufficient size and shape to substantially prevent honey bees passing through the netting material.

Abstract: A crop material is woven in a leno weave configuration from weft tapes and groups of warp elements, the warp elements in each group cross at a cross-over point between adjacent weft tapes, and the adjacent groups of warp elements spaced apart across the weft at a distance greater than about 8 mm.

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.

Abstract: A netting material is knitted from at least two synthetic material yarns of which one is an opaque and the other is a transparent or translucent or different opaque yarn. A knitted netting material comprises a plurality of primary yarns knitted to form a mesh construction having an arrangement of primary apertures defined by yarn intersections and yarn connecting portions between yarn intersections, and a plurality of secondary yarns crossing over the primary apertures to form secondary apertures within the primary apertures.

Abstract: A reflective netting material suitable for providing over and/or adjacent the plant as bird netting, insect netting, shadecloth netting, windbreak netting, or hail protection netting, is knitted, woven, or non-woven, from a synthetic monofilament, yarn, or tape or combination thereof formed from a resin comprising at least one white pigment such that the monofilament, yarn, or tape reflects at least 30% solar radiation on average across the UV (wavelength about 280-400 nm), visible (wavelength about 400-700 nm) and very near infrared (wavelength about 700-800 nm) ranges, and which transmits at least 10% or 5% on average of solar radiation across the wavelength range about 800-2500 nm.

Abstract: A ground cover sheet material for use in agriculture is described. The sheet material has a greater length than width and is woven from at least two different types of tapes. The two different types of tapes have different reflecting, absorbing or transmission properties. Each type of tape forms at least 5% or 10% of the surface area of the ground cover material.

Abstract: The present invention relates to ground cover sheet materials and to ground cover sheets comprising such materials. The ground cover sheet material absorbs more solar radiation than it reflects in the UV range of about 280-400 nm, and reflects more solar radiation than it either transmits or absorbs in the visible range of about 400-700 nm and near infrared range of about 700-800 nm, and transmits at least part of solar radiation in the range about 800-2500 nm and at least part of solar radiation above about 2500 nm.

Abstract: The present invention relates to ground cover sheet materials and netting materials, and to ground cover sheets and netting comprising such materials. The materials comprise a green pigment derived from one or more pigments, and at least one additional pigment which does not significantly decrease the amount of solar radiation transmitted by the polymer-pigment mixture in the range of about 700 nm-2500 nm, and/or at least one additional pigment which decreases the amount of solar radiation transmitted by the material in the blue light range of about 440 nm-490 nm and in the red light range of about 620-700 nm.

Abstract: A netting material having a length dimension and a width dimension much smaller than the length dimension is formed by threads knitted or woven together. The netting material has a main portion comprising knitted or woven apertures, a reinforced edge portion at or adjacent each longitudinal edge of the netting material comprising a longitudinal row of knitted or woven fastening features, and a reinforced intermediate portion between the reinforced edge portions. The reinforced intermediate portion has a first longitudinal row of knitted or woven fastening features and a corresponding second longitudinal row of knitted or woven fastening features. In use, the netting material is folded so that the first longitudinal row of fastening features and the second longitudinal row of fastening features are brought together to form a double-layered row of fastening features.

Abstract: Crop protection netting is of a knitted mesh construction, knitted such that at yarn intersections in the netting multiple yarns of which the netting is formed are knitted around each other to define the netting mesh apertures so that the netting is stretchable in multiple directions, and wherein connecting yarn portions between said yarn intersections extend substantially linearly between intersections, and wherein at least one of the multiple yarns of which the netting is formed comprises a tape, and/or in addition to the multiple yarns of which the netting is formed (whether comprising a tape as above or otherwise) the netting also comprises multiple yarns or tapes extending through the netting (as a ‘lay-in’) woven through the mesh apertures and/or around intersections of the multiple yarns of which the netting is formed.

Abstract: Described is a reflective ground cover sheet material (1) in which longitudinally extending opposite side margins (A) of the sheet material are stronger than a longitudinally extending center section between the side margins of the material. Also described is a reflective ground cover sheet material (1) having longitudinally extending opposite side margins (A) of the sheet material of lower porosity than a longitudinally extending center section between the side margins of the material.
