Abstract

On the evenness tester, a yarn is drawn by a pair of rollers, a signal of uneven yarn quality is output to a processing branch machine through a sensor, the processing branch machine processes the signal to obtain a plurality of testing parameters for representing the yarn quality and a series of testing pattern parameters, the plurality of groups of testing pattern data are stored, after the batch of samples are tested, the batch of pattern data are called for statistics, statistical values such as an average value, a maximum value and a minimum value are rapidly obtained, an average curve, an upper limit curve and a lower limit curve are drawn, a group of statistical curves are formed and are drawn on the same graph, the method enables the quality distribution characteristic discrete degree of the samples to be clear at a glance, saves labor, saves printing paper, and the number of the samples can be 30 times or 50 times.

Description

On testing apparatus, to the method for analyzing textile material

The present invention is a kind of on testing apparatus, the textile material quality information is carried out the method for statistical study with figure.

Yarn evenness tester is the equipment of the irregular signal of a kind of test yarn evenness quality, one one thread, by a pair of roller traction, pass through sensor, the irregular signal of output yarn qualities is to handling extension set, handle extension set this signal is handled multiple test parameter and a series of resolution chart parameter that draws the sign yarn qualities, and many groups test parameter is handled again.For a collection of sample of yarn, only depending on certain group test parameter or a certain figure to assess yarn qualities is science, inaccurate not, and must carry out analysis-by-synthesis to the test result of a collection of sample of yarn, can draw correct conclusion.

Homemade present dried instrument, its comprehensive analysis method only carries out statistical computation to many groups test parameter, calculate its mean value, extreme value etc. and be to go to see by naked eyes by artificial many similar figures are stacked together to the processing of graphic parameter, so neither directly perceived, inaccurate, the expense that wastes time and energy again printer paper, and the contemporary advanced dried instrument of UT-3 type bar, except that test parameter is added up, multiple output pattern is added up, adopt displacement mode, putting together of many sets of curves machinery formed the figure (87103757) with 3-D effect, this method has just been saved artificial stacked work, and pattern analysis work also will manually go with the naked eye to see, and is not directly perceived, do not understand, analyze inconvenience more, and this method can only be placed 12 curves at most.

The present invention seeks to overcome weak point of the prior art, invent a kind of analytical approach that on testing apparatus, can reflect whole sample mass information, make analysis result more accurately, rapidly, simultaneously easy and simple to handle, improve the instrument service efficiency.

The present invention is used for test as rove, and the microscler textile material of yarn or sliver and so on also provides a kind of method of representing its quality information, may further comprise the steps:

A〉the test material sample is by the sensor of a pair of roller traction by a testing apparatus, the irregular signal of the exportable specimen quality of this sensor;

B〉on the processing extension set, the irregular signal of specimen quality is handled, with multiple test parameter and a series of resolution chart parameter that draws the characterization test sample quality;

C〉above-mentioned many group resolution chart parameters are stored in the memory;

D〉treat this Lot sample end of test (EOT) after, access test parameter and graph data is added up, obtain statistical value and on same figure, draw statistic curve.

Here said statistical value comprises the mean value and the extreme value of a certain characterisitic parameter of this Lot sample at least, certainly, can also be the statistical value under some other state.

Here said statistic curve is averaged curve, upper limit curve, the lower limit curve that a certain characterisitic parameter of this Lot sample is drawn at least, also the corresponding curve of above-mentioned statistical value.

Like this, the mass distribution feature dispersion degree of this Lot sample is come into plain view.Advantage of the present invention be save time, laborsaving, economize printer paper, the quantity of sample also can accomplish 30 times or 50 times, statistical graph still day can show printer prints output on screen simultaneously.This method has overcome the shortcoming of above-mentioned two kinds of methods, makes analysis result more rapidly accurately, and the service efficiency of instrument that makes easy and simple to handle obviously improves, to yarn qualities analysis, weaving process quality tracking Control highly significant.

The invention will be further described below in conjunction with accompanying drawing.On the dried instrument of bar, one one thread, by a pair of roller traction, pass through sensor, the irregular signal of output yarn qualities is to handling extension set, handle extension set and this signal is handled multiple test parameter and a series of resolution chart parameter that draws the sign yarn qualities, above-mentioned many group resolution chart data storage are got up, after treating this Lot sample end of test (EOT), accessing this batch graph data adds up, obtain the system value rapidly, as mean value, maximal value, minimum value, and draw out averaged curve, upper limit curve, lower limit curve forms one group of statistic curve and is painted on same the figure, and accompanying drawing is that the one group of statistic curve curve 1 (going up surface curve) after passing through to handle is the maximal value of this BT(batch testing) CV (L) curve, curve 2 (intermediate curve) is the mean value of this BT(batch testing) CV (L) curve, represent the average level of this Lot sample, curve 3 (lower curve) is the minimum value of this BT(batch testing) CV (L) curve, and the Regional Representative changes the zonation of BT(batch testing) CV (L) curve between two curves up and down.
