Embodiment Construction

[0037] The diameter of air holes on the circumferential surface of the dust cage friction false twister adopted in the present invention is 0.6-0.9mm, the number of air holes is 900-1100, and the suction negative pressure adopted is 2400-3500Pa.

[0038] The production process of sulfone fiber core-spun composite yarn is as follows:

[0039] The drafting single-strand fiber bundle output from the front nip that front rubber roller 22 and front roller 21 form is twisted into yarn together with core filament 13, and is spun into the core-spun yarn that short fiber wraps long filament. The core-spun yarn enters the two dust cage friction false twisters 1 again, and is simultaneously subjected to the plasticizing of moisture in the wet tank 20 and the tight twisting action of the two dust cages, and then is output into the yarn guide hook 23, and is then The wrapped yarn 16 is wrapped and bundled, spun into a compact compound polysulfonamide core-wrapped composite yarn 19 , and fi...

Abstract

The invention relates to polysulfonamide core-spun and wrapped composite yarns produced in the textile industry. Core-spun yarns consist of core yarn polyester yarns and externally-wrapping polysulfonamide fibers, and flame-retardant viscose filaments wrap the core-spun yarns. A conditioning friction tight composite spinning device for the composite yarns comprises a pair of dust cage friction false twisters corresponding to each spinning spindle, wherein a dust cage consists of two thin-wall sleeves and is fixed on an internal air suction pipe; the internal air suction pipe is connected with a main air suction pipe through a rubber pipe; the main air suction pipe is connected with a negative pressure fan; a conditioning groove is formed above the dust cage; a core yarn tensioner and a core yarn bobbin are arranged above a front roller and a front rubber roller; and a wrapped yarn tensioner and a wrapped yarn bobbin are arranged above a yarn guide hook. The invention has the advantages that: the polysulfonamide core-spun and wrapped composite yarns have a unique structure, a few hairs and high strength and can replace the conventional plied yarns, doubling and twisting processes are eliminated, the ration of coarse yarns can be improved by 40 percent compared with that of the conventional process, the tearing strength of the prepared fabric can be improved, and the structure of a ring spinning frame is not changed when the device is adopted.

Description

technical field [0001] The invention relates to the field of textile industry, specifically refers to a polysulfonamide core-wrapped composite yarn and a wet friction compact composite spinning device used in the production of a traditional ring spinning machine, which is specially used for polysulfone Ring spinning processing of rayon core-wrapped composite yarns. Background technique [0002] Polysulfonamide is a high-performance fiber developed by my country with independent intellectual property rights. Its scientific name is Polysulfonamide (PSA). Lun 1313, polysulfone can be widely used in protective materials, filter materials, electrical insulation materials, friction materials and other fields. [0003] Aramid sulfone fiber has low strength, poor crimping performance, low surface friction coefficient, and serious static electricity in the spinning production process. Therefore, drawing, roving, and spinning processes will encounter difficulties to varying degrees. ...
