Quality, research and development Creating specialised green yarns for every requirement, using experience and intuition Despite the excellent results that we have so far achieved, our research team continues to work tirelessly in order to improve the performance of Radigreen in each of its fields of use. Every sport has its own specific requirements for synthetic playing fields, and our main objective is to anticipate them in order to create a product that responds exactly to the needs of those who play on artificial grass. At Tessiture Pietro Radici S.p.a., we are convinced that the best results come with time, after having scrutinised every detail and having worked closely with our clients. Our laboratory is equipped with state-of-the-art instruments in order to guarantee the characteristics and quality of our raw materials, semi-finished products and finished products over time. Quality Control checks are carried out according to the sector’s specific ISO, EN and DIN regulations. Our desire to protect our customers and provide them with a guarantee means that as early as 1996, we gained UNI EN ISO 9001 certification. A new yarn is born of the fruits of laboratory research and market needs. Rigorous testing is already being carried out in our labs, where we are currently undertaking tests for stability to light and atmospheric agents. Test Room Test: accelerated ageing by means of exposure to UV rays Purpose of the test: To determine the exposure time taken for the initial physical and mechanical properties of the yarn to degrade by 50%, according to DIN 53387 regulations as stated in the technical specification. Light resistance guarantee Even although it is not possible to establish an exact linear relationship between external exposure and that produced using the XENOTEST (it must be borne in mind that there are environmental effects that cannot be reproduced in accelerated tests), we can affirm according to our experience and the tests carried out that: - in areas with irradiation equal to 100 kcal/cm/year (e.g.    Milan, Madrid, Tokyo), one hour of exposure to XENOTEST    corresponds on average to 20-22 outdoor hours; - in areas with an irradiation equal to 140 kcal/cm/year (e.g. Miami, Sydney, Casablanca), one hour of exposure to XENOTEST    corresponds on average to 14-15 outdoor hours; - in areas with an irradiation equal to 200 kcal/cm/year (e.g. Saudi Arabia, Death Valley, Sahara), one hour of exposure to    XENOTEST corresponds on average to 6-7 outdoor hours. In order to find out the stability of each of our articles, please refer to the Xenotest hours given in the section “Properties and special treatments” for the relative Technical Specification. In areas such as Miami, for example, where our light stability tests are carried out, factors such as temperature, humidity, atmospheric salinity and very strong irradiation can influence the chemical, physical and mechanical characteristics of the yarn, as can altitude, rarefied air and pollution (see world graph with areas). But our tests indoors do not end here. Before a yarn can enter the Radigreen family, it must pass a whole range of tests, including MFI, FTIR (infrared spectroscope – Fourier’s transform) and DSC. After having also passed the TABER test (equipment used to check wear and abrasion resistance), the yarn can proceed to outdoor tests; tests to check UV ray resistance and resistance to mechanical stress carried out in collaboration with internationally recognised organisations. Our task of rigorous monitoring and thorough checking carries on into the later stages of production, when our clients use the yarn to manufacture the finished green carpet. Our knowledge of every phase of the production and use of synthetic grass and the stages of its lifecycle allows us to continuously make improvements to existing yarns and to create entirely new ones in order that the game may continue on an ever greener field.
