METHOD TO PRODUCE COMBINED THREAD BASED ON SHORT FIBRES AND DEVICE FOR ITS REALISATION Russian patent published in 2011 - IPC D02G3/18 

FIELD: textile, paper.

SUBSTANCE: method to produce a combined thread on the basis of short fibres includes feeding fibres into the area of the auxiliary thread movement, fixing fibres on this thread and feeding the produced combined thread into a winding area. Besides, a water slip is produced previously from short fibres, and short fibres are fed in a composition of a water slip jet into the movement and twisting area of at least two auxiliary threads. Prior to the combined thread winding, it is squeezed and dried. Also the device is proposed to produce a combined thread, which includes a zone of fibre feeding, a zone of spinning using an auxiliary thread and a zone of winding, besides, the fibre into the feeding zone arrives in the form of a water slip. Between the spinning zone and the winding zone there is additionally a zone of the combined thread drying.

EFFECT: produced combined threads may be used to produce a wide spectrum of articles, in particular, to produce high-temperature heat protection and insulation fabrics, tapes, furnace conveyor belts, sealing cords to insulate perimetres of the hot area gates.
