Description
Technical field
The invention belongs to textile chemical fiber measuring instrument field, the test device of a kind of chemical-fibres filaments percent thermal shrinkage and
Its method of testing, it is applicable to quality control and textile enterprise, testing agency's inspection to fiber quality of chemical fibre mill.
Background technology
The percent thermal shrinkage of chemical-fibres filaments is one of major parameter characterizing fibre structure and character, is to shape with chemical-fibres filaments
And the integrated performance index that the process such as post processing is relevant, it characterize product post processing and product take in dimensionally stable
Property.The percent thermal shrinkage of chemical-fibres filaments and postfinishing process, product dyeability have this substantial connection, directly affect fabric taking
Energy and appearance.Therefore, percent thermal shrinkage method of testing and the device thereof of research chemical-fibres filaments is of great significance.
The measuring method of the percent thermal shrinkage of chemical-fibres filaments, is intended to measure chemical-fibres filaments respectively under certain pre-set criteria tension force
Length before heating and the length after heat shrink, ask for tested chemical-fibres filaments according to its length difference divided by the length before heating
Shrinkage factor value, measure and automatically calculate sample mean percent thermal shrinkage and the coefficient of variation after some samples.Test chemical-fibres filaments
According to sample testing, percent thermal shrinkage method requires that difference has baking oven for heating method and boiling water thermal contraction method, have according to test sample difference
Single method or hank knotting method, for the measuring method of specimen length before and after heating, domestic mostly be manual method, begin with instrument in recent years
Device.Instrument measuring method abroad with Germany Textechno company produce TEXTURMAT ME type chemical-fibres filaments crispatura rate test
Instrument be this instrument of representative use hank knotting method sample, chemical-fibres filaments crispatura rate test with percent thermal shrinkage test be incorporated in an instrument
On, the former requires that dynamometry load is big, and the latter requires that dynamometry load is little, and both share an instrument, and unavoidably to reduce chemical fibre long
The precision of silk thermal contraction test result.It is made without rate test of crispaturaing for chemical-fibres filaments only need to do percent thermal shrinkage test
Product is more not suitable for.It addition, this instrument is fixed for hank knotting sample upper end in dynamometry mode, force cell moves down insertion
Above lower hook dish, the most afterburning to hank knotting sample, measurement is the length of hank knotting sample at some tension, this measuring method dynamometry
Force acting on transducer be by lower downwards, to instrument force value demarcate calibration bring difficulty, not only affect its measuring accuracy and also make to operation
With making troubles.In addition, this instrument hank knotting sample is girth 1 meter, and length 500mm after suspension, instrument is bulky, price
Expensive.The above-mentioned of Germany substantially copied by the YG368 type full automatic filament crimp contraction tester that recent year produces
, there is similar technology problem in the instrument of type product.Therefore, according to domestic chemical-fibres filaments production development, special in the urgent need to one
Testing for chemical-fibres filaments percent thermal shrinkage, change above-mentioned instrument dynamometry mode, instrument volume is little, the chemical-fibres filaments that measuring accuracy is high
Thermal contraction tester, here it is the main purpose of this patent research and development.

Go out, gradually inject upper between hook dish 4 and the space of hank knotting sample 1, when silk fork 12 be moved upward to upper hook dish 4 bottom phase
After contact, start to hold up hook dish 4, guided by wire guide 8 and wire guide 9 and drive hank knotting sample 1 and lower draw-bar dish 6
Upper shifting, wire guide 8 and wire guide 9 are packed on the upper and lower side frame of sample cylinder 25 respectively, when move on lower draw-bar dish 6 with
Stopped by lower limiter 7 when lower limiter 7 contacts and stop mobile；
E, lower draw-bar 3 are by after resistance stop motion, and upper hook dish 4 continues to be driven shifting, and hank knotting sample elongates inner tensions gradually
Increase, in order to not make tension spikes, uphill process automatic retarding, when hank knotting sample tension force increases to pre-set criteria tension force, instrument
The umber of pulse that device is sent drive stepping motor by computer records specimen length, i.e. hank knotting sample length under standard tension force automatically
Degree；
After F, test hank knotting specimen length complete, dynamometry frame 10 declines homing, silk 12 drawing by skewed slot guide rail 15 of fork automatically
Lead effect bounce back to again in machine, after testing the sample of a hank knotting, sample cylinder turns an angle, instrument start under
One hank knotting sample carries out length testing；
G, surveyed hank knotting specimen length for heating front length, are length after heat treated after heat treated before non-heat treated,
Chemical fibre long filament heat shrinkage is calculated by both differences.
In the inventive method implementation process, accurately measure chemical-fibres filaments according to computer umber of pulse and step motor control technology
Length change before sample heating and after heating, length resolution is 0.01mm, it will be apparent that improves and can chemical-fibres filaments sample heat receive
The measuring accuracy of shrinkage, structure is reliable, and fault rate is greatly lowered.Use dynamometry frame to measure tension force suffered by hank knotting, can accurately survey
Quantity reset standard tension value, resolution is 0.1cN, reduces because pre-tension error is to the length before the heating of long filament sample and after heating
The impact of degree measurement result.After hank knotting sample hangs, length is changed into 250mm, instrument volume and weight by the 500mm of external instrument
Amount considerably reduces, and can measure 20 samples every time, improves the credibility of test result.
It is only present pre-ferred embodiments in sum, is not used for limiting the practical range of the present invention.The most all depend on
Equivalence change and the modification that the content of scope of the present invention patent is made, all should be the technology category of the present invention.
