4、Used for testing indexes of single fiber, such as breaking tenacity, elongation at break, loab at specified elongation, elongation at specified load, creep, etc.
3、Effect degree of regain, relative humidity and test number on breaking tenacity of saw ginned cotton and roller ginned cotton were analyzed respectively through orthogonal test.
5、Character: high breaking tenacity, high modulus, low shrinkage, good creep-resistance and dimensional stability, one of the best reinfocement materials for semi-steel radial tire.
2、Used for testing breaking tenacity and elongation at break of raw silk in skein and bobbin.
1、breaking tenacity
