C) whether the weight of judging described spun yarn meets predefined weight range, if meet, then the flying quality of spun yarn is good.
The inventor finds that the weight of spun yarn flying quality and spun yarn is closely related, therefore, by measuring the weight of the spun yarn that sprays in the special time, can judge the flying quality of spun yarn.
Before detecting, the present invention preestablishes the weight range of the good spun yarn of flying quality, specifically sets in accordance with the following methods:
Adopt air-jet loom to weave cotton cloth on spun yarn, weaving efficiency, fabric quality are estimated, and choose the good spun yarn of weaving efficiency height, fabric quality as standard model;
Adopt the described checkout equipment of technique scheme to detect described standard model, during detection, the pressure of compressed-air actuated pressure during with jet weaving cotton cloth is identical, and can set arbitrarily detection time, is set at 4min in the present embodiment;
To weigh after the spun yarn collection that blow out.
In order to make testing result more accurate, repeatedly standard model is detected, weighs, get the mean value that each time detects, weighs, set the flying quality weight range that in 4min, blows out of spun yarn preferably, the result is referring to table 1, and table 1 is the weight range of the good spun yarn of the flying quality that the embodiment of the invention is set.
The weight range of the spun yarn that the flying quality that table 1 embodiment of the invention is set is good
The weight that table 1 is blown in 4min for the good all kinds of spun yarns of flying quality.
Preestablish after the weight range, testing sample detected, may further comprise the steps:
Adopt the described checkout equipment of technique scheme to blow out testing sample, the pressure of compressed-air actuated pressure during with jet weaving cotton cloth is identical, and the detection time of detection time when preestablishing weight range is identical;
The spun yarn that collection blows out is also weighed to it, and is more accurate in order to make testing result, described testing sample repeated to blow out, weighs 3 times, and get its mean value;
Whether the weighed average of judging described testing sample meets predefined weight range, if meet, promptly this weighed average drops within the predefined weight range, the flying quality of described testing sample is good, when being used to weave cotton cloth, weaving efficiency is higher, and the fabric quality that obtains is better; If do not meet, promptly this weighed average is not within predefined weight range, and the flying quality of described testing sample is relatively poor.
In other embodiments, to detection time of spun yarn being set at other random times, as 5min or 10min, at this moment, when preestablishing weight range, also be 5min or 10min or other random times its detection time accordingly.In other embodiments, the weight that also can adopt the spun yarn that blows out in the unit interval detects the flying quality of spun yarn, and at this moment, when preestablishing weight range, its detection time is unrestricted.
Checkout equipment provided by the invention and detection method can be used to detect the flying quality of spun yarn, thus select flying quality preferably spun yarn be used to weave cotton cloth, and then improve follow-up weaving process efficient, improve the quality of the fabric that obtains.In addition, checkout equipment provided by the invention and detection method can also be used for the quality control of spun yarn, promote the improvement to the spun yarn quality.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
