China's first 7m wide geotextile and felted tire base fabric dual-use polyester spunbonded acupuncture production line has been successfully tested in Shandong Weifang Beijing Jiuji Group recently, marking China's first production of linoleum tire base fabrics using polyester filament yarn The production line was born. It is understood that the equipment and technology of the production line are developed by Dalian Huayang Chemical Fiber Engineering Technology Co., Ltd. and special design is made for spinning box structure, drafting pipe arrangement, separators, fins, etc., as well as for needle-punching machines. The improvement of the form and the rational use of a number of new technologies and new processes developed by the company have successfully achieved the localization of polyester spunbonded felt tire base fabric products. The vertical and horizontal strength ratio of the product reached 1.1 or less, and all other indicators fully met the national standards. Felt tire base fabric is a building waterproof material. In the past, glass filament or polyester staple fiber was used as a felt tire base fabric. The tensile strength and heat resistance were poor, and physical indicators were not satisfactory. The use of polyester filament yarn as a felt tire base fabric has high tensile strength and low grammage. This kind of base fabric is made of domestic glue and treated with dip-impregnated terminal waterproof tar felt. The test indicators have reached the national standard. . The production line also reserves the structure and position for the bottle-sheet homogenizing device in the spinning section, which can realize the dual-use of slice and bottle-chip, and is fully prepared for the future production of polyester bottle-pieces as raw materials. The successful development of this production line will greatly reduce the market price of similar products and will have a profound impact on the domestic waterproof material market.
