    摘要： A greenhouse screen comprising strips of film material that are interconnected by a yarn system of transverse threads and longitudinal threads by means of knitting, warp-knitting or weaving process to form a continuous product. The film material comprises a highly transparent, biaxially oriented, UV and flame-stable polyester film which is provided on at least one side with a coating which reduces the reflection of visible light. The greenhouse screen is particularly suited for the cultivation of plants with high light requirements.

    摘要： A greenhouse screen strips of film material that are interconnected by a yarn system of transverse threads and longitudinal threads by means of knitting, warp-knitting or weaving process to form a continuous product, wherein at least some of the strips comprise a film material in the form of a single- or multilayer polyester film is disclosed. The film material has a transparency of at least 93.5% and is provided with at least a first anti-reflective coating or layer on a first side of the film material.

    摘要： A greenhouse screen is described with strips of film material that are interconnected by a yarn system of transverse threads and longitudinal threads by means of knitting, warp-knitting or weaving process to form a continuous product is disclosed. At least some of the strips include a film material in the form of a single- or multilayer polyethylene film having a thickness of 10-70 micrometers. Said film has at least 2-4 wt.-% SiO2 particles having a D50 of 2-10 micrometers. The film is advantageously used as a screen providing light scattering properties particularly suited for greenhouse applications.

    摘要： A greenhouse screen comprising strips of film material that are interconnected by a yarn system of transverse threads and longitudinal threads by means of a knitting, warp-knitting or weaving process to form a continuous product is provided. At least some of the strips comprise a polyester film having a transparency of at least 93%, said polyester film having at least one base layer B comprising a thermoplastic polyester and a UV stabilizer. The polyester film has a first and a second surface, wherein a permanent anti-fog coating is applied to at least one of the first or second surfaces of the polyester film. The anti-fog coating has a lower refractive index than the base layer B.A process for producing said film is also disclosed.

    摘要： A greenhouse screen comprising strips of film material that are interconnected by a yarn system of transverse threads and longitudinal threads by means of knitting, warp-knitting or weaving process to form a continuous product is disclosed. At least some of the strips comprise a film material in the form of a single- or multilayer polyester film wherein the film contains at least 1.0 wt.-% SiO2 and a maximum of 2.5 wt.-% SiO2, and has a spreading factor of at least 2 and not more than 8. The greenhouse screen as disclosed herein has a reduced flammability and light scattering properties particularly suited for greenhouse applications.

    摘要： The invention refers to a greenhouse screen comprising strips of film material that are interconnected by a yarn framework of transverse threads and longitudinal threads to form a continuous product, wherein the yarn framework is thermally bonded to at least one side of the strips of film material, wherein also those parts of the yarn framework that is thermally bonded to the strips have liquid-transporting capacity by capillary action. The amount of yarn in the yarn framework interconnecting and holding the strips can herewith be reduced.

    摘要： Described is an insect net strip produced from a wide insect net which has been cut in a warp direction (xnet) by means of a one-step ultrasonic cutting and welding process. The insect net strip includes warp yarns and weft yarns extending substantially perpendicular to each other and at least 90% of the warp and weft yarns are monofilament yarns made of a thermoplastic material. After cutting and welding process the insect net strip has a first and a second edge extending parallel to said warp yarns each including a deformation zone being constituted by consolidated thermoplastic material deriving at least from said weft yarns. The deformation zone has a width (wdz) in the transverse direction (ystrip) of between 0.5-35 times the weft yarn diameter (øwe). At least 90% of gaps between adjacent weft yarns in the deformation zone are closed by consolidated thermoplastic material at least from the weft yarns which has been melted together to form a continuous or substantially continuous reinforced band-shaped edge portion of said insect net strip. The insect net strip is suitable for use in accordion-style constructions in greenhouse ventilation openings. A method for producing the insect strips is also described.
