Non-woven fabrics have great application prospects in the construction field

Since 2002, the output of non-woven products has been increasing steadily. Among them, the application in the field of geotextiles is increasing at an average annual rate of about 6%. According to the professional report of'bavern inmntive', the construction industry was the second largest application field of the non-woven fabric industry in 2010, accounting for 18.2% of the non-woven fabric market share, second only to the wipe cloth market. Under the dual role of new product development and the expansion of new application areas in the construction industry, the application range of non-woven fabrics in the construction industry will be further expanded in the next few years, and the demand will further increase. The main driving force behind this development trend is that the development of the construction industry increasingly tends to be thermal insulation, energy saving, sound insulation and comply with corresponding environmental protection standards. Even in thin materials, polyester non-woven fabrics, as functional textiles, can also play a role in preventing excessive cold and moisture. For example, they can be easily used in roof structures, quickly and conveniently used as thermal insulation materials, quickly replace the facade of a curtain wall system or cover cracks, and can also be used to isolate impact sound. They are ideal substitutes for materials such as foam, glass wool, and asbestos, whether for renovation or new construction, because the latter generally lack the flexibility required to achieve a good seal. Not only that, non-woven fabrics can also resist environmental impacts, and the recycling rate is also high. Flexible materials have good prospects, and they have entered the high-tech field. In this regard, smart non-woven fabrics have emerged, which incorporate conductors or conductive materials. Take the “smart floor” as an example. Through sensors, they can automatically activate lights and monitor the fall of elderly people who retired at home. In terms of industrial non-woven fabrics, so-called roofing materials account for a high proportion of the global market, exceeding 420,000 tons per year. On the one hand, the application in this field is mainly focused on calendering polypropylene (pp) spunbond non-woven fabrics, which are generally laminated with a layer of breathable pp film and placed between the roof tiles and the load-bearing wooden structure. In addition to these roof liner membrane materials, asphalt roofing has been commonly used for flat roofs as a covering layer. This material is made of needle punched and heat-set polyester spunbond non-woven fabric treated with an acrylic adhesive. The ability of these non-woven fabrics for these purposes is mainly due to their functions: moisture-proof, breathable, insect-proof, mold-proof, and shape and temperature stability; easy to use, they can be installed, glued or welded together on site; in addition, It has anti-fatigue, anti-impact and anti-puncture properties, anti-separation, and good compatibility with standard paints and coatings. oerlikonneumag (Oerlikon Neumag) is one of the world's leading non-woven technology suppliers. The company can provide systems and equipment for processing bituminous roof membrane materials, roof liner materials and geotextile substrates, as well as complete sets of spunbonded non-woven fabric production equipment from polymer pellets to roll products. 'Our equipment not only has a higher output, but also has the characteristics of saving operating costs (including energy, maintenance and labor costs). 'Oerlikon-Neumag non-woven fabric expert ingom? Dr. hlmann explained. He is very optimistic about the application prospects of spunbond non-woven fabrics in the construction industry because of its obvious cost advantage. He said:'The development trend of using spunbonded non-woven fabrics to replace glass fiber products is already obvious. Asphalt roofing materials and geotextiles are the best examples in this regard. This development trend also applies to many other non-woven fabrics for construction, including those used for reinforcement or emissions. '
