Description
Technical field
The present invention relates to the method for testing of sizing fabric length growth rate and machine yarn length measuring capture device used.
Background technology
Sizing length growth rate is one of three large key process parameters of sizing operation, tests and monitoring contributes to carrying out technique adjustment to it, improves sizing quality.
The percent that after sizing length growth rate refers to starching, the length of sizing increases relative to the length of warp thread before starching, is expressed as:
(formula 1), wherein E is sizing length growth rate, L
2for sizing exports length, L
1for warp thread feeding length; Or use
(formula 2), wherein V
2for output line speed, V1 is input end linear velocity.The length growth rate of sizing is by sizing process, warp thread is subject to serous infiltration, the elongation of drying and the effect of warp-wise tension force produces, the height of length growth rate directly affects the intrinsic mechanical properties of the yarn such as brute force, elasticity of sizing, thus the end breakage of impact rear road weaving process and weaving efficiency.
Existing sizing test of elongation rate method adopts the direct method of measurement: the linear velocity measuring output terminal roller and input end roller in sizing process respectively, then compare computing by formula (2) and draw.Rotation due to roller relies on to drive with the yarn friction operationally of its surface contact, and yarn tension meeting occurrence dynamics in operational process changes, yarn all can cause between yarn and speed measuring roller reasons such as the friction force of roller are not enough and produce Relative sliding, thus cause roller tachometric survey error, make the length growth rate obtained lose authenticity.
Summary of the invention
The object of the invention is, for the low deficiency of the length growth rate authenticity obtained when art methods and proving installation test sizing length growth rate, to provide a kind of and more truly can reflect the method for testing of the sizing fabric length growth rate of sizing length growth rate and machine yarn length measuring capture device used.
In order to realize above-mentioned technical purpose, the present invention adopts following technical scheme:
First object of the present invention is, a kind of machine yarn length measuring capture device is provided, comprise gland and base, the working surface of described gland is provided with pressure head, the working surface of described base is provided with groove, the geomery of described groove and described pressure head matches, and described base is fixedly connected with described gland;
Described base and described gland are bolted to connection;
Described base and described gland are by connecting and fixing connection;
Described base and described gland are rectangular parallelepiped, and the mating surface of the two matches;
Be provided with the kerve be arranged in parallel in the bottom of described groove, match the press strip being provided with on described pressure head and be arrangeding in parallel with described kerve.
Second object of the present invention provides a kind of method of testing of sizing fabric length growth rate, comprise the steps:
(1) warp thread without starching of some and certain length, is intercepted as sample warp thread;
(2) the described warp thread through starching of equal number and length, is intercepted as sample sizing;
(3) the dry mass W of described sample warp thread, is weighed respectively
0with the dry mass W of described sample sizing
1;
(4), according to following formula
Wherein: E is the length growth rate of sample sizing
S is the rate of sizing
W
0for the dry mass of sample warp thread
W
1the dry mass of sample sizing;
Further, destarch method is adopted to obtain the rate of sizing S of sizing;
Further, the device that described sample warp thread and/or sample sizing one of adopt claim 1-4 every intercepts.
Method of the present invention is adopted to test the length growth rate of sizing, warp thread dry mass W0 before starching, the dry mass W1 of sizing after starching, affect few by the factor in sizing process, and taken into account the impact of the rate of sizing when calculating, so the length growth rate of the sizing recorded is more objective and true, not by the impact of yarn variety etc.
Adopt machine yarn length measuring capture device of the present invention, structure is simple, easy to operate, when intercepting yarn, only by straight for yarn combing in groove, the yarn that gland can intercept certain length need be compressed, the stretching again of yarn can not be caused, objective sizing length growth rate can be obtained.

Embodiment
Below in conjunction with drawings and Examples, the present invention is elaborated.
The method of testing of sizing length growth rate of the present invention comprises the steps:
1, the sample warp thread without starching of some and certain length is intercepted;
2, the sample sizing through starching of equal number and length is intercepted;
3, the dry mass W of sample warp thread is weighed respectively
0with the dry mass W of sample sizing
1;
4, destarch method is adopted to measure the rate of sizing S of sizing;
5, according to following formula
Said method is Indirect Determination, its principle be according to warp thread in sizing process while stressed quilt " attenuating ", also at quilt " drawing-down ", namely the quality of unit length alleviates, straighten connect measure length be changed to indirect inspection, more same length feeding end with output terminal mass change, take into account the percent mass penalty after considering warp sizing, i.e. the rate of sizing simultaneously.
As Figure 1-4, the structure of the machine yarn length measuring capture device of preferred intercepting length of yarn is as follows, it comprises gland 1 and base 5, the working surface of gland 1 is provided with pressure head 2, the working surface of base 5 is provided with groove 4, the geomery of groove 4 and pressure head 2 matches, and base 5 and gland 1 are provided with connecting hole 3.During use, be placed in groove 2 by parallel along the direction of groove 2 for the yarn needing to intercept, with comb combing to straight, gland 1 is pressed on base 5, bolt pre-connection base and upper cover is put in connecting hole, tentatively step up clamper, make pressure head tentatively compress yarn, make yarn stretch under maintenance some tension, tighten clamper under state parallel to each other.The cross section of preferred groove and pressure head is match square or semicircle.Gland and base are rectangular parallelepiped and length A is equal.Unnecessary yarn bundle is cut off along servicing unit two ends with sharp blade.The cross section of preferred groove and pressure head is match square or semicircle.Preferred gland and base are rectangular parallelepiped, and the surface of matching of the two matches, and are conducive to like this intercepting the fixed length of yarn, facilitate blade cuts.
In order to clamp a small amount of yarn better, the bottom of groove 4 is provided with kerve 7, match with this kerve 7 is provided with press strip 6 on pressure head.Like this, when amount of thread is few, yarn enters in kerve 7, compresses the yarn in kerve 7 by press strip 6, and due to kerve 7 little, so be more conducive to combing yarn to be intercepted.
