Abstract

FIELD: light industry; applicable in production of materials for manufacture of upholstered furniture, chairs for transport facilities, and heat and sound insulation. SUBSTANCE: method for production of bonded materials includes preparation of fibrous mixture of low-quality wool containing wastes of synthetic fibers in the amount of 5-20 mas.%, formation of fibrous lap with the help of bin with rectangular outlet, preliminary joining of lap with binding agent, impregnation of lap with binding agent, drying, cooling and cutting. Preliminary joining of lap with binding agent is accomplished by spraying of binding agent solution, first, on one side of lap and then, on the other side. After each spraying of binding agent, fibrous lap is subjected to drying. Consumption of binding agent is taken in such amount that after each drying, at the stage of preliminary joining of lap, gain in weight is 6-8% of the initial weight of lap, and gain in weight of finished material is 30-40%. EFFECT: provision of production of soft flexible material, at least, 20 mm thick.

Изобретение относится к легкой промышленности и может быть использовано при производстве материалов, предназначенных для изготовления мягкой мебели, кресел для транспортных средств, а также теплозвукоизоляции. Изобретение позволяет изготавливать мягкий, эластичный материал с толщиной не менее 20 мм. Способ изготовления клееных нетканых материалов включает подготовку волокнистой смеси из низкокачественной шерсти, содержащей отходы синтетических волокон в количестве, равном 5-20 мас.%, формирование волокнистого холста с помощью бункера с прямоугольным выходным отверстием, предварительное скрепление холста связующим, пропитку холста связующим по схеме "в жале валов", сушку, охлаждение и резку. Предварительное скрепление холста связующим осуществляют путем распыления раствора связующего сначала с одной стороны холста, а затем с другой. После каждой операции распыления раствора связующего волокнистый холст подвергают сушке. Расходы связующего выбирают такими, чтобы после каждой сушки на стадии предварительного скрепления холста привес составлял 6-8% от массы исходного холста, а привес готового материала был равен 30-40%.The invention relates to light industry and can be used in the manufacture of materials intended for the manufacture of upholstered furniture, seats for vehicles, as well as thermal and acoustic insulation. The invention allows the manufacture of soft, elastic material with a thickness of at least 20 mm. A method of manufacturing glued non-woven materials includes the preparation of a fiber mixture of low-quality wool containing synthetic fiber waste in an amount of 5-20 wt.%, The formation of a fibrous canvas using a hopper with a rectangular outlet, pre-bonding the canvas with a binder, impregnating the canvas with a binder according to the scheme " in the sting of shafts, "drying, cooling and cutting. The preliminary bonding of the canvas with a binder is carried out by spraying a solution of the binder first on one side of the canvas and then on the other. After each operation of spraying the binder solution, the fibrous web is dried. The binder costs are chosen such that after each drying at the stage of preliminary bonding of the canvas, the weight gain is 6-8% of the mass of the original canvas, and the weight gain of the finished material is 30-40%.
