Abstract
A network layer is provided that contains at least one thermoplastic biodegradable substance. The network layer contains at least one colored first material in a first direction, the first colored material exhibiting a first absorption coefficient, and at least one colored second material in a second direction, the second colored material exhibiting a second absorption coefficient. The colored first material and the colored second material are in contact with each other, a coloration of the first material is different from a coloration of the second material, and the second absorption coefficient is different from the first absorption coefficient.
Claims13
A network layer for use in landscaping or horticulture, the network layer comprising:
- at least one thermoplastic biodegradable coloured first material exhibiting a first absorption coefficient, the coloured first material consisting of warp yarns in a warp direction, each warp yarn having a colouration that is the same along the entire length of the warp yarn and each warp yarn extending the entire length of the network layer;
- and
- at least one thermoplastic biodegradable coloured second material exhibiting a second absorption coefficient, the coloured second material consisting of weft yarns in a weft direction, each weft yarn having a colouration that is the same along the entire length of the weft yarn and each weft yarn extending the entire length of the network layer,
- wherein:
- the entire network layer is a woven layer of the warp yarns and the weft yarns,
- the coloured first material and the coloured second material are in contact with each other,
- a colouration of the coloured first material is different from a colouration of the coloured second material, and
- the second absorption coefficient is different from the first absorption coefficient.
