Description

PROTECTIVE NETTING AGAINST SMALL INSECTS AND FINE PARTICLES AND A METHOD FOR PRODUCTION THEREOF
FIELD OF THE INVENTION
The present invention relates to netting, especially useful for hindering the passage of small insects and any fine particles through said netting. The present invention particularly relates to any fibrous netting, providing proper air ventilation, comprising a combination of plurality of bristly fibers and non-bristles fiber; wherein the bristle fibers comprising frizzles, hairs or the like, incorporated in the warp and/or the weft fibers of said netting, and wherein said bristles hinder the passage of said small insects and any fine particles through the mesh (e.g. the space between the fibers); and further wherein said non-bristles fibers providing the mechanical stability of said netting. The present invention also relates to a method for the production of the aforementioned netting and its use for various agricultural, industrial or domestic purposes.
BACKGROUND OF THE INVENTION
Fibrous netting are commonly used for various agricultural, industrial or domestic purposes. One particular use of the aforementioned netting is for protecting the passage of insects to greenhouses and the like.
Those netting traditionally comprise waφ and weft witted mesh of fibers. Increasing number of the warp and weft fibers weave in a netting, bigger the mesh number, smaller the mash size (i.e., the opening through the netting), and harder is the passage of undesired insects through the netting. Thus, Israeli patent No. 119,919 states that for a mesh size of 0.3 to 0.83mm is effectively hindering the passage of the Bemisia tabaci insect.
Traditionally, both warp and weft are composed of homogeneous mesh, made of either smooth polymeric fibers or thin metal wires. The stability of those homogenous netting is enabled by using strong fibers. Nevertheless, it is quite difficult and costly to produce stable netting of a small mesh size, and thus effectively hindering the passage of insects or any other fine particles through the netting.
On one hand, cotton fibers and many other bristle fibers are unstable mechanically. On the other hand, non-bristle fibers enables the production of stable netting, yet the weaved netting is of respectively mesh size, allowing the passage of small insects and fine particles to penetrate through the mesh of the warp and weft fibers of the netting.
Surprisingly, I have found a novel, cost effective and most efficient netting, enabling to hinder the passage of small insects and fine particles, yet allowing of proper air ventilation throughout the netting.
SUMMARY OF THE INVENTION
The aim of the present invention is thus to provide A fibrous netting, providing proper air ventilation, especially useful for hindering the passage of small insects and any fine particles through said netting; comprising a combination of plurality of bristly fibers and non-bristly fibers; wherein said bristle fibers, comprising frizzles, hairs or the like, incorporated in the warp and/or the weft fibers of said netting, so said bristles hinder the passage of said small insects and fine particles through the space between the fibers; and wherein said non-bristly fibers providing the mechanical stability of said netting.

Another object of the present invention is a method for the production of the netting defined above, by weaving the fibrous fibers, so the waφ fibers and/or the weft fibers comprising bristly fibers and non-bristly fibers in the quantitative ratio of 2:1 to 1 :4.
Reference is made now to Figure 1, presenting the insects and fine particle protective fibrous netting according to the present invention, comprising bristly fibers (1) (e.g., the fibers shaded in the present invention in dark colors) comprising bristles (2) and non-bristly fibers
(3) (namely the smooth white fibers described in the present invention), in a quantitative ratio of 1 :1 in either the waφ fibers ( ) and the weft fibers (ii). The space between the waφ and weft fibers is referred in the present invention as the mesh size (4).
Reference is made now to Figure 2, presenting the small insects and fine particle protective fibrous netting according to the present invention, comprising bristly fibrous and non-bristly fibers, in a quantitative ratio of 1 :2 in either the waφ fibers and the weft fibers.
Reference is made now to Figure 3, presenting the small insects and fine particle protective fibrous netting according to the present invention, comprising bristly fibrous and non-bristly fibers, in a quantitative ratio of 1 :2 in the waφ fibers and 1 : 1 in the weft fibers.
Reference is made now to Figure 4, presenting the small insects and fine particle protective fibrous netting according to the present invention, comprising bristly fibrous and non-bristly fibers, in a quantitative ratio of 1 : 1 in the weft fibers.
Lastly, reference is made now to Figure 5, presenting the small insects and fine particle protective fibrous netting according to the present invention, comprising bristly fibrous and non-bristly fibers, in a quantitative ratio of 1 :2 in the waφ fibers and 2: 1 in the weft fibers.
