To be able to react to the emerging changes caused by climate change, increasing UV exposure must be taken into account, particularly in the area of fruit, vegetable and berry plantations, and the harvest must be protected accordingly. Conventional protection systems are reaching their limits, which must be overcome by new concepts such as intelligent, self-regulating textile components or a hybrid design. Today's protection systems for the above-mentioned applications are mostly designed for protection against weather events (hail). A change in fruit protection is necessary as damage, and thus yield losses, are increasingly attributable to sunburn in the crops grown. The trigger responsible for this is increasing UV exposure. In Germany, there is a clear trend in terms of increased sunshine duration (as an indicator of UV exposure). The implementation of modified protective nets, which can react actively to changing environmental conditions thanks to new materials in yarn development, can help to solve this problem. The yarns required for this are produced by mixing in additives during the manufacturing process (melt spinning) that exhibit photochromic or thermochromic behavior at corresponding threshold values. This means that the yarns modified in this way can change their light permeability and allow more or less sunlight to penetrate to the plants.
