Abstract
The invention relates to a device for testing the hair feather state of yarn under the action of high-speed airflow, which comprises a yarn feeding roller, a yarn passage, a compressed air inlet, an annular airflow passage, a yarn observation pipe and a yarn guide roller. The yarn feeding roller and the yarn guide roller are used for fixing yarn, the compressed air inlet is a circular passage andis directly connected with the annular airflow passage, the wall face of the annular airflow passage is in a streamline design, and airflow in the annular airflow passage forms tangential airflow at an inlet of the yarn observation pipe. By changing the supply gas pressure of compressed air, the tangential airflows with different speeds at the inlet of the yarn observation pipe are obtained, thussimulating different running speeds of the yarn, overcoming the defect that the hair feather state of the yarn is difficult to test under the action of high-speed running, and ensuring the accuracy ofa test result.
Description
Technical field
The present invention relates to device for testing hair feather state, particularly relate to the device for testing hair feather state of a kind of yarn under action of high-speed airflow.
Background technology
Being created in the spinning process of filoplume is inevitably, and be relevant, also relevant with the situation and the parts of textile machine with the raw material that uses.Filoplume is the important indicator that characterizes yarn property, also is the problem that is always perplexing weaving processing, although can by singe, starching, waxing attachment wait and improve the Yarn filoplume situation, do not tackle the problem at its root.More present novel spinning technology, as compact spinning technology, its basic goal also is to reduce filoplume as far as possible, improves the yarn product quality.
The harm of filoplume is mainly: (1) forms new cotton knot in weaving, influence fabric appearance; Make the adjoining yarn company of twining mutually when (2) weaving, cause the wefting insertion difficulty; (3) in each operation of downstream, filoplume is come off because of rubbing, and forms flyings, contaminated environment, is detrimental to health, and also can produce new fault and yarn and fabric quality are descended.
The assay method of filoplume instrument is that optical detection device is detected length adjustment to the relevant position of distance yarn according to the filoplume of setting at present, and detecting element is a light-sensitive element.Yarn, is given prominence to yarn and is surpassed and set the inswept light-sensitive element of filoplume that detects length by test point with constant speed, causes the light-sensitive element light flux variations, makes it to change into the signal of telecommunication, forms count pulse.Stipulate according to existing testing standard " FZ/T 01086-2000 textiles Yarn filoplume assay method ", cancellation 60m/min test speed, change 30m/min into, but at present loom go into the latitude rate mostly more than 1000m/min, so the filoplume state of filoplume instrument test can't react the filoplume state in the weft weaving process.Yet the present inventor finds, if improve yarn test speed, because the effect of air drag may cause the lodging of yam surface filoplume, can't reflect the Yarn filoplume state by test result.Under yarn high-speed cruising state, the test system hardware dynamic response requirement is also improved greatly simultaneously, must guarantee enough measuring accuracies.Therefore at present yarn researching and analysing of filoplume running status in the high-speed cruising process lacked effective tester.
