Abstract
The invention relates to an agricultural shed cloth and solves the technical problem by realizing even light receiving of the crops, increasing the firmness of the shed cloth and improving the adaptability to ventilation and water permeability. The agricultural shed cloth provided by the invention comprises transparent film strips and is characterized in that: the transparent film strips (1-1), or shading-reflective film strips (1-2) and the transparent film strips (1-1) are alternately arranged to form warp strips or weft strips; shading-reflective film strips (1-2) and transparent film strips (1-1) are alternately arranged to form weft strips or warp strips, so as to form the shed cloth (1) in weft / warp knitting shape; and the shading-reflective film strips are aluminum plated films or aluminium foil composite layers using a transparent material as a base material.
Description
Technical field
The present invention relates to a kind of capital goods in the agricultural sector, specifically a kind of agricultural canopy cloth, is usually used in various booths.
Background technology
Polyhouse-based agriculture needs a large amount of canopy cloth in producing, and is used for to the insect protected of crops sunshading and thermal insulating.Traditional canopy cloth or the close material of knitting, light transmission ventilation is poor, or dredges and knit material, can't stop enough sunlight and insect pest.Chinese patent CN200973288 discloses a kind of curtain of insulation of sunshading, and this invention forms with polyester filament light transmission film and shading-light reflecting membrane by its braiding, has formed part shading-reflective curtain, has well overcome the deficiency of Traditional Agricultural with canopy cloth.But the light transmission part of this invention is strip, makes crop be subject to light even not; And selection is long filament, and weave effect is poor; Water-permeable and air permeable adaptability is not good, and application surface is narrow.
Summary of the invention
The technical issues that need to address of the present invention are to make crop be subject to light more even, increase the firmness of canopy cloth and improve the adaptability to air-and water-permeable.
A kind of agricultural canopy cloth of the present invention, comprises light transmission film bar, and feature is light transmission film bar, or shading-light reflecting membrane bar alternate with light transmission film bar be through bar or latitude bar; Shading-light reflecting membrane bar is alternate with light transmission film bar is latitude bar or through bar, becomes to be arranged in canopy cloth through knitting device shape; Described shading-light reflecting membrane bar is for take aluminizer or the aluminium foil composite bed that light-transmitting materials is base material.The design only uses light transmission film bar alternate with shading-light reflecting membrane bar the arrangement of knitting device shape, and strength increase own is more durable.Particularly on shading-light reflecting membrane bar, there are aluminizer or aluminium foil composite bed, the outer interception (can make the light transmittance of whole canopy cloth between 40 ~ 50%) that can flash back the sunlight of this aluminous layer, interior (because its base material is light-transmitting materials) can reflect reflection action again to the light entering in canopy, add the acting in conjunction of upper side reflective membrane and ground facet reflective film, can make light in booth inside through multiple reflections, light intensity in booth is evenly distributed, makes crop be subject to illumination more even.
As a kind of scheme, on described canopy cloth, be compounded with transparent membrane extra play.Preferred transparent membrane extra play is PE or PET material, and thickness is 0.010 ~ 0.030mm.Due to the different growth period of different crops, different planting areas, crop of the same race, the air-and water-permeable of canopy cloth is required to be all not quite similar, compound layer of transparent film extra play on canopy cloth layer, do not affect basic printing opacity and control effect, can effectively intercept the gentle body exchange of free surface moisture in canopy cloth.Moreover, being compounded with after extra play, the intensity of agricultural canopy cloth also improves a lot.
As canopy cloth through (latitude) bar, preferred matcoveredn on the aluminizer of shading-light reflecting membrane bar or aluminium foil composite bed.Aluminizer or this bi-material of aluminium foil composite bed, from heavy and light, are applicable to booth and use, and as a kind of means of agricultural production, are widely used, and buying finished product or certainly processing are also all than being easier to.On it, matcoveredn can be to reflectorized material---and aluminium coated or aluminium foil layer, effectively to protect, extend its reflection function, and then extend the canopy cloth operating period.
Requirement based on agricultural booth to the performances such as printing opacity temperature control wind resistance of canopy cloth, described light transmission film bar is PE or PET material, and thickness is 0.006～0.050mm, and width is 2～7mm; Described shading-light reflecting membrane bar be take the aluminium foil composite bed that PE or PET are 0.010～0.100mm as base material, the thickness aluminizer that is 0.007～0.050mm or thickness; width is 2～7mm; its protective layer material is PEGS Polyethylene glycol succinate, terephthalate polyester or terephthalic acid (TPA) butanediol polyester, and thickness is 0.001～0.003mm.
As preferably, described light transmission film bar and shading-light reflecting membrane bar width equate, both can adapt to produce in enormous quantities and get the raw materials ready, can also be woven into picture and text by style design, or particular block is made to specific shaded effects, even can weave for Different Crop different geographical the canopy cloth of different shaded effects.
Compare with background technology, the invention has the beneficial effects as follows: only use light transmission film bar and shading-light reflecting membrane bar to form through knitting device, strength increase own is more durable; On shading-light reflecting membrane bar, there are aluminizer or aluminium foil composite bed, can reflect again the light entering in canopy, make crop be subject to light more even; And without adding polyester filament, reduced cost; Increase extra play, there is rainproof function, can effectively intercept the gentle body exchange of free surface moisture in canopy cloth.This product, at agronomy, gardening, the heatstroke prevention in summer of enterprise's house, summer outdoor work, all has good effect.
