【発明の詳細な説明】 〈産業上の利用分野〉 本発明は編織物に杢調と称する特殊な外観を与える杢調
編織物用糸条の評価方法に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a method for evaluating yarns for heathered knitted fabric which gives a knitted fabric a special appearance called heathered.

を混在させるなどの方法が知られている。<Prior Art> As a means for producing a yarn that gives a knitted texture to a knitted fabric, a yarn of a different color is usually used at the yarn production stage, for example, parallel spinning during spinning, take-up of composite yarn, and drawing of composite yarn during drawing. Alternatively, a method is known in which yarns showing different colors after dyeing are used, or a temperature condition during drawing is intentionally selected in a drawing unstable region to mix undrawn yarns.
ところで杢調は「杢調こなれ」という言葉でその特性を

題がある場合に、糸条製造工程のどの部分に改良を加え
たら良いのかなどの情報が把握し難かった。Various efforts have been made to manufacture yarns with a good smoothness, but there is no conventional method to estimate and evaluate the smoothness at the yarn stage, and a knitted fabric is prepared on a trial basis. It has been conducted to visually evaluate the shade of dyeing mainly by dyeing, but not only the evaluation takes time, but if there is a problem, which part of the yarn manufacturing process should be improved. It was difficult to grasp information such as whether or not.
〈発明の目的〉 本発明はかかる従来技術の問題点を解決するためになさ

ことを特徴とする杢調編織物用糸条の評価方法である。<Structure and action of the invention> That is, the present invention is to measure the spot signal of the yarn corresponding to the light and shade unevenness of the dyeing over a predetermined length, and continue the dark dye corresponding portion or / and the light dye corresponding portion from the spot signal. The heather when the yarn is knitted and woven according to the frequency distribution pattern is calculated based on the correspondence between the frequency distribution pattern previously measured and the heathered tone in the knitted cloth, which is calculated in advance. It is a method for evaluating a yarn for a heathered knitted woven fabric, characterized in that the texture is evaluated in the state of the yarn.

で評価できるようにしたものである。As a result of various studies, the above-mentioned present invention was found to find that the above-mentioned frequency distribution pattern shows a good correspondence with the conventional visual evaluation, and the measurement of the frequency distribution pattern with various sample yarns in advance. And the knitting woven fabric by visual evaluation, and measure the correspondence between the frequency distribution pattern in the yarn and the knitting woven fabric, and based on this correspondence, the frequency distribution pattern By this, the heat treatment can be evaluated in the state of the yarn.
ここで「染色の濃淡差に対応する糸条の斑信号」とは糸

も良い。Here, the "spot signal of yarn corresponding to the difference in shade of dyeing" is a stain signal that indicates the difference in shade of the direct dye as the output of a yarn dyeing measuring device (for example, FYL500 manufactured by Toray Industries, Inc.). It is also possible that it is not a signal showing the difference in shade of direct dyeing like the output of an Evenestesta (for example, Wuster tester made by Zellviger Uster), but it corresponds to the difference in shade of dyeing It may be a corresponding signal, that is, a thickness variation signal.
以下、本発明を図面を用いて詳細に説明する。Hereinafter, the present invention will be described in detail with reference to the drawings.

The thickness variation signal of the output of the Even tester 1 is processed by the band pass filter 2, and after the direct current component and the high frequency component are cut, it is sampled by the A / D converter 3 every 10 msec and converted into a 12-bit digital signal.
It is once stored in the floppy disk storage device 5 by the processing of the personal computer 4.

本例では略OVとなった。Fig. 2 is a polyester yarn (75 denier.36 multifilament) for heathered knitted woven fabric produced by drawing a yarn partially heat-treated in the spinning process and partially crystallized in the drawing process at a draw ratio lower than usual. Is an example of a patchy signal of the output of the bandpass filter 2 when the Evenes tester 1 is applied at 25 m / min.
In the figure, the signal above the reference value V 0 corresponds to the thick dyed portion where the yarn is thick and the signal below the reference value V 0 corresponds to the light dyed portion where the yarn is relatively thin. Note that the reference value V 0 was an average output value in the measurement section, but because of the bandpass filter 2, it was approximately OV in this example.
基準値V0はその他製造条件の対応値等適用できる。前述

の測定データを取り込むようにしている。The reference value V 0 can be applied to values corresponding to other manufacturing conditions. In the floppy disk storage device 5, the signal as shown in FIG. 2 is sampled every 10 msec, digitized and recorded. Normally, the heathered tone is evaluated by making a test piece (knitted fabric) with a yarn length of 20 to 80 m and dyeing it, so even with this device, the measurement data of spot signal for 20 to 80 m per time is measured. I am trying to capture.

Is calculated by the personal computer 4, a frequency distribution is created with respect to this value, and is printed by the printer 6, and the gradation deviation is estimated and evaluated by the frequency distribution.

ある。Fig. 3 shows that the sample yarn was run for 3 minutes at the Ibnes tester at a running speed of 8m / min (sample length 24m), and the frequency distribution of the deep dyeing duration Di in the deep dyeing corresponding part was converted to the deep dyeing length of 0.5c.
Division of m intervals (0 to 0.5, 0.5 to 1, 1 to 1.5 ……… 14.5 to 15c
It is calculated and printed out in m). (A), (B), and (C) of the figure show the light-stained (abnormal), normal, and deep-stained (abnormal) by visual inspection of the knitted fabric sample, respectively, but the frequency distribution pattern of the figure Clearly differs according to the visual inspection, and according to the present invention, it is possible to determine the mottled quality by the pattern of the frequency distribution of the continuation time Di or the continuation length of the unstretched portion of the deep dyeing corresponding portion in the yarn state. I understand. Further, the cause of quality defects can be investigated from the pattern.

布を作成し、これらも参照することが好ましい。The frequency distribution pattern of the deep-dyeing corresponding part shows the best correspondence for the heather, but the light-dyeing corresponding part also shows a considerable correspondence (corresponding to the background darkness), so the frequency distribution of the light-dyeing corresponding part Can also be applied to evaluation, and it is desirable to evaluate both. Further, since the portion corresponding to the deep-dyeing is particularly conspicuous, depending on the brand, it is preferable to create a frequency distribution for the peak value Pi and the area Si of the deep-dyeing portion, and also refer to these.

きわめて大きかった。The present invention is as described above. For various sample yarns, the above-mentioned frequency distribution pattern in the yarn state according to the present invention is measured in advance, and the graininess of the knitted fabric is evaluated by visual evaluation by the conventional method. Correspondence between the frequency distribution pattern in the knitted fabric and the heathered tone in the knitted fabric was measured in advance, and thereafter visual evaluation in the knitted fabric was omitted, and the yarn produced based on this correspondence was measured. Heathering is evaluated at the yarn stage based on the frequency distribution pattern, and the quality can be checked more easily and earlier than the conventional method, and the obtained results are extremely large.
