Twisted reinforced thread

FIELD: textile, paper.

SUBSTANCE: twisted reinforced thread contains an unarmoured component in the form of polyether twisted yarn and reinforced polyether core yarn, core of the reinforced yarn is formed by two complex yarns with different linear density each. The ratio of linear densities of the yarns is 1:0.5-0.7.

EFFECT: improving the physical and mechanical properties of the yarn due to the creation of a homogeneous elastoplastic composition and increasing the wear resistance of the yarn.

SUBSTANCE: twisted reinforced thread comprises non-reinforced component in the form of polyester complex thread and reinforced yarn with core of polyester complex thread and braiding. Polyester complex thread of non-reinforced component has twist that makes 0.38-0.69 of twist of twisted reinforced thread. Braiding of reinforced yarn is formed with polyester staple fibres.

EFFECT: increased relative rupture load of twisted reinforced thread and its operational properties.

FIELD: composite materials.

SUBSTANCE: inventions concern components of composite materials, allowing auxetic characteristics, i.e. negative or efficiently negative coefficient of Poisson, structure made of components of composite material and method of its manufacturing. Component of composite material, allowing negative effective coefficient of Poisson contains passing along the axis the first and the second component. The first component is located around of the second component by spiraling in the form of one or more turns, dispersed lengthway relative to mentioned axis. Changing of stretching or compressing load to the first component rouses changing of radial position of the second component relative to this axis. At changing of stretching or compressing load to the first component it takes place further change of spiral diameter of the first component, and changing of spiral diameter of the first component leads to the second component gains spiral form, and/or rouses changing of spiral diameter of the second component, and spiral diameter of the second component increases at reduction of spiral diameter of the first component, while spiral diameter of the second component decreases at increasing of spiral diameter of the first component. From two or more components of composition material it is formed structure, in which both of these components are located near to each other or in the contact to each other. Method of component manufacturing of composition material, allowing negative effective coefficient of Poisson, is in forming of the first and the second components, covering by means of winding and/or spinning and/or covering of the first component around of the second element in the form of one or more turns, dispersed lengthway lengthwise of the second component.

EFFECT: receiving in industrial conditions components of composite materials, allowing stable structure and extended range of properties and ranges of application.

SUBSTANCE: invention relates to the technology of metallised material production for shielding from electromagnetic radiation in a broad range. Metallised material ''Nanotex'' is made of synthetic monofilament thread with diameter of 30-50 micron, and a number of threads is 30-160 threads per cm and surface density is 10-50 g/m2. Material has orifices between beam threads and shoots, size of which ranges within 1d-9d, where d is thread's diameter. Metal pads with predetermined surface resistance can be distributed over the material by weave or woven methods. The invention ensures production of the material with stable performances having high shielding capacity from different types of radiation including high-frequency radiation ranged from 300 to 16000 MHz.

EFFECT: production of the material with stable performance having high shielding capacity from different types of radiation.

FIELD: textile industry, in particular, production of combined current-conductive threads used for manufacture of protective current-conductive gloves.

SUBSTANCE: method involves producing current-conductive threads having linear density of from 200 to 400 tex by forming current-conductive blank through winding of two-four plated threads onto one carbon fiber used as core, said winding being performed in various directions and number of windings constituting 5-20 coils per 1 m; providing further winding using threads Pycap having greater rupture loading. Winding equipment to be used should provide 260-370 coils per 1 m.

EFFECT: improved strength, increased wear resistance and reduced electric resistance of threads produced by method.

SUBSTANCE: method involves introducing two non-twisted complex threads into fibrous flow of semi-finished product obtained in the process of drawing by means of drawer of ring spinning machine; determining distance between threads by multiplying empiric coefficient of 0.7-1.3 by partial of dividing the value of linear density of joining thread (tex) by value of linear density of joining thread fiber (tex), said values being multiplied by diameter of joining thread fiber (mm); in formed twisting triangle, twisting threads together with joining thread while dividing joining thread fibers into two parts to produce reinforced components, which are in their turn twisted together with each other.

EFFECT: improved physico-mechanical properties of threads owing to creating homogeneous elastoplastic composition, and increased wear-resistance of thread.
