Photoselectivity can be placed in a classification between two main types of textiles: those that act as a light filter and those that act as a light absorber. This means that the sun resistance in a woven mesh depends on the material, yarns and weaving method used.Photosensitive fabrics are made of materials that filter or absorb sunlight to protect eyes, flesh or some sensitive elements from direct sunlight. If the fabric is optimally woven mesh, the mesh can be chosen to act as a UV filter. A target fabric is characterized by resisting color change under direct sunlight. This means that the fabric retains its original color under sun exposure. These fabrics are often treated with a lightweight solution that blocks some of the ultraviolet light and are considered the most versatile textiles for outdoor uses.
Light absorbing fabrics are often the preferred material for sun protection. These fabrics are characterized by absorbing sunlight rather than resisting it. The materials used to create light-absorbing fabrics are often dyed or dyed with UV dyes or dyestuffs to give the fabric a sunlight-resistant color. This characteristic is ideal for areas exposed to very high temperatures and direct sunlight. In meshed fabrics, photoselectivity is used to improve durability, wear resistance and also protect the sensitive elements of the fabric. This feature allows the user to wear the fabric longer, even for extended periods of time without having to worry about wear and tear due to direct sunlight. These fabrics are UV resistant, resist warping and color changes caused by direct sunlight and do not cause rapid fading of colors.
That provides a woven mesh
In addition to UV resistance, fabrics can be treated to provide additional protection to enhance durability. This includes treatments with waterproof coatings, pestysan treatments, Softshell coatings, etc. These coatings increase the mesh’s resistance to the sun and external elements, maximizing durability and abrasion resistance. Ultimately, the photoselectivity of a woven mesh offers improved resistance to direct sunlight and provides protection to users. This feature allows the user to wear the fabric longer without worrying about wear and tear. In addition to improving durability, photoselectivity can also provide additional protection against ultraviolet light to ensure the beauty of the fabric. Photoselectivity is a specific characteristic aspect of certain crops that profoundly affects not only the yield of the product but also its quality. This is all due to the change in the photoperiodic response of a crop.
Photoselectivity, as the name suggests, is the ability of crops to absorb or reflect different wavelengths of sunlight. Sunlight is a vital factor in photosynthesis that results in crop growth and development. This is because plants are able to absorb different compounds from light that can be harnessed to perform their metabolic process. Depending on the crop, specific wavelengths may be required for the compounds to be absorbed and the energy needed for photosynthesis to occur. In the case of crops with photoselectivity, such as tomatoes, biocrops, ornamentals, flowers and most grasses, this is particularly remarkable. This is because these crops have a tendency to respond better to specific light depending on color and shade. This characteristic response directly affects yield and product quality, as crops develop faster under specific lights.
Why is it important to take care of photoselectivity in a crop?
To achieve the best protection for crops, it is important to be careful with photoselectivity. This is partly because the sun’s rays have a direct influence on plant growth, especially during the early stages. Thus, when direct sunlight exceeds certain levels, crops begin to be affected, and some may even die. On the other hand, the correct light and heat levels are essential for the growth and development of crops, which helps to obtain an optimal result at the end of their cycle. This balance between sun and shade also influences the insects that may visit the crop, such as bumblebees, which pollinate the flowers. In the case of bees, it is advisable to have between 6 and 8 hours of light each day for them to do their work.
From the environmental point of view, it is also recommended (for both plants and animals) to have an acceptable degree of photoselectivity, which implies establishing appropriate areas for the development of planting and establishing spaces that minimize the impact of light on the animals living in the area. These protected areas are essential for the balance between the natural resources and the crops raised in that environment, constituting an adequate regime that allows both to subsist and reuse the land without suffering great affectations. A correct photoselectivity control also helps to improve crop homogenization, i.e. to allow all crops to develop their cycles in the same way, which, if achieved, generally translates into healthier crops and less use of energy to achieve the same result.
