Description
Technical field
The present invention relates to textile lab instrument, especially a kind of electronic fabric strength testing instrument.
Background technology
The brute force value of textile is to weigh the important physical index of quality of textile products, textile power value index is of a great variety, and commonly used has: be used for finished product test fabric tension ultimate strength, bursting strength, tear brute force, separation strength, seam strength, tearing brute force, tensile elasticity power and antiskid and move brute force etc.These power value indexs are because its definition has nothing in common with each other, and anchor clamps, draw speed, drawing process, the power value of testing tool read a little different requirements.
The tension failure brute force of fabric is meant certain-length (100mm normally, 200mm), the fabric of certain width, one end is clipped in to be decided in the chuck, the other end is clipped in the moving chuck, moving chuck stretches with certain speed (normally 100mm/min), until breaking, the maximum, force value that records in this process is the tension failure brute force of fabric, also should record the elongation and the stretching time of fabric when breaking simultaneously.
The tearing brute force of fabric is meant the fabric of certain-length (normally 200mm), certain width, cut off along its length flatly in the centre of Width, respectively both wings are clipped in and decide in chuck and the moving chuck, moving chuck stretches until end with certain speed (normally 100mm/min), the power value that writes down in this process normally waveform changes, with the mean value of each power value peak value as tearing brute force.
Tensile elasticity power has two kinds of balancing methods usually, the one, the elongation during certain tensile force, be meant certain-length (normally 100mm), fabric one end of certain width is clipped in to be decided in the chuck, and the other end is clipped in the moving chuck, and moving chuck is with certain speed (50mm/min normally, 100mm/min) stretch, record elongation when being stretched to the certain force value, certain intervals after this stretch off and in the time so that the power of tracking value writes down once elongation again after arriving interval time.The 2nd, the tensile force during certain elongation is meant that fabric one end of certain-length (normally 100mm), certain width is clipped in to be decided in the chuck, the other end is clipped in the moving chuck, moving chuck is with certain speed (50mm/min normally, 100mm/min) stretch, parked certain intervals writes down the power value after the time when being stretched to certain elongation, tries to achieve elastic restoration ratio through calculating then.
Also have in addition fabric separation strength, bursting strength, tear brute force, seam strength and antiskid and move brute force etc., its test process of different force value tests also has nothing in common with each other.
Before the present invention makes, the instrument performance of a great variety that is used for the textile strength test differs, most of instrument can only record single force value index, as: strength tester can only record the ultimate strength elongation at break of yarn, the separation strength tester can only record the separation strength of compound fabric, the fabric elasticity instrument can only record the elastic restoration ratio of fabric, has only indivedual instruments can record two to three kinds of indexs of fabric.The draw speed that different force value tests requires has nothing in common with each other, textile strength test instrument is had relatively high expectations to stretching or jacking speed, stretch or the precision of the power value index that jacking speed has fluctuation directly to have influence on to record, and existing these instruments are because motor speed has fluctuation, so its stretching or jacking speed also have fluctuation.
Summary of the invention
Can only record single force value index or two to three kinds of power value indexs in order to overcome existing textile strength test instrument, because of stretching or the fluctuation of jacking speed causes recording the coarse deficiency of power value index, the invention provides a kind of electronic fabric strength testing instrument, this electronic fabric strength testing instrument can not only be surveyed multiple power value index, and the power value index that records is accurate.
