Description
Изобретение относитс к соединению синтетических тканей с помощью ультразвука и может быть использовано в швейном производстве , а также в химической и горнообогатительной промышленности дл производства изделий типа фильер. Известен способ ультразвуковой сварки ткапей, содержащих термопластичные волокна капрона, найлона, лавсана и т. п. При известном способе расплавл ютс нити как основы, так и утка. Однако известный способ не обеспечивает достижени прочности на сдвиг. Цель предлагаемого изобретени - повышение прочности шва. Дл этого ткань в области образовани шва облучают до температуры, соответствующей температуре плавлени нитей с низкой температурой плавлени . При таком способе сварки прочность соединений , работающих на сдвиг, составл ет 80-90% от прочности основного материала. Ультразвуком облучают до плавлени нитей одной группы ткани только основы или только утка, тогда как нити другой группы оставл ют нерасплавленными. В том случае, когда до плавлени довод т нити по утку,, нити основы остаютс нерасплавленными и используютс в качестве армирующих элементов и наоборот. Предмет изобретени Способ ультразвуковой сварки синтетических тканей из нитей с различной температурой плавлени , например, по утку и основе, отличающийс тем, что, с целью повышени прочности шва, ткань в области образовани шва облучают до температуры, соответствующей температуре плавлени нитей с низкой температурой плавлени .The invention relates to the combination of synthetic fabrics using ultrasound and can be used in the clothing industry, as well as in the chemical and mining industry for the production of dies. The known method of ultrasonic welding of caps containing thermoplastic fibers of nylon, nylon, lavsan, etc. With the known method, the threads of both the warp and the weft are melted. However, the known method does not achieve shear strength. The purpose of the present invention is to increase the strength of the seam. To this end, the fabric in the area of seam formation is irradiated to a temperature corresponding to the melting point of the low melting point filaments. With this method of welding, the strength of the shear joints is 80-90% of the strength of the base material. Ultrasound is irradiated to melt the yarns of one fabric group of only the warp or only the weft, while the threads of the other group remain unmelted. In the case when weft yarns are melted, the warp threads remain unmelted and are used as reinforcing elements and vice versa. The subject of the invention is a method of ultrasonic welding of synthetic fabrics from threads with different melting points, for example, weft and warp, characterized in that, in order to increase the strength of the seam, the fabric in the region of the seam formation is irradiated to a temperature corresponding to the melting temperature of the threads with a low melting point.
