Technical field:
The invention belongs to slashing performance detection technique fields, and in particular to a kind of yarn tension peak detection instrument.
Background technique:
At present in the textile industry, the index of tradition evaluation sizing for weaving performance has very much, such as yarn abrasion increase rate,
Ultimate strength increment rate (i.e. enhancing rate), extension at break slip (subtracting the rate of stretching), filoplume reduced rate etc., in addition there are pass through slurry
Coating and infiltration the ratio of liquid and the performance of serous coat etc. carry out Indirect evaluation sizing for weaving performance.These evaluation indexes some
Test trouble, the testing time is long, some tests are inaccurate, some information are unilateral.So with the development of scientific and technological level and to spinning
The continuous improvement of fabric quality requirement, realization are particularly important the quick and precisely evaluation of sizing quality.
The enhancing rate of sizing, the measurement for subtracting the rate of stretching all are realized using single yarn tester in the prior art, specifically
Mode is that single yarn tester is respectively adopted to carry out strength measurement to more raw yarns, more sizing, obtains raw yarn and sizing is respective
Average development length when average ultimate strength and fracture, is then calculated slurry according to the average ultimate strength of sizing and raw yarn
Yarn enhancing rate, what average development length when being broken according to sizing and raw yarn was calculated sizing subtracts the rate of stretching.
This mode needs slowly to stretch yarn until breaking, and detection speed is very slow, therefore, in the enhancing rate to sizing
With when subtracting the rate of stretching and detect, be generally only to extract several sizing immediately from a batch of sizing to detect, with this
The quality of sizing by the gross being judged, and in usually production process, the quality inspection of sizing can only be judged by diameter, shape, and
It to enhancing rate and the rate of stretching can not be subtracted is measured in real time.
In process of production, it has been found that sizing is compared with raw yarn, under same elongation, of the sizing relative to raw yarn
Power is significantly improved, and therefore, is found by this, has investigated and a kind of knitted using the peak tension of sizing to evaluate sizing
The method for making performance.But the premise for implementing this method is the tension in the weaving process needed to yarn (including raw yarn and sizing)
Peak value is detected, and is not able to detect the instrument of the peak tension during yarn weaving at present.
