Description
Technical field
The present invention relates to a kind of yarn twist stability test device and method of testing.
Background technology
Short fiber yarn must be twisted in the resultant yarn process, and the internal stress that produces in twisting process when yarn can not get discharging, and can make yarn produce backtwisting power.The backtwisting power of yarn can make yarn the crooked and entanglement that the following process process is carried out smoothly occur affecting under without the state of tension force or low-tension so that the twist plays pendulum.
Following defective appears in unstable permanent the causing of yarn twist in the textile process: 1, the one-side weft-knitted fabric wale is crooked; 2, the looped pile of Weft knitting knop cloth (pile stitch) and INTERLOOP (liner tissue) produces kink; 3, the single side weft-knitting Strip Fabric produces skew of weft; 4, the kink of weft yarn in the weft yarn picking process in the woven fabric process.The problems referred to above have a strong impact on carrying out smoothly of knitting presentation quality and woven fabric processing.Twist stability to short fiber yarn is measured and is estimated, and helps to alleviate yarn twist unstable on weaving the impact of processing, is conducive to simultaneously guarantee product quality.
For the yarn that contains the thermoplasticity chemical fiber, usually before weaving processing, adopt various dead twist methods, to stablize the twist of yarn.The yarn twist stability test device can be estimated the dead twist processing effect.
For non-thermoplastic fibers such as cotton, fiber crops, silk, hair and viscose glue classes, can not improve its twist stability by the dead twist processing mode, it is carried out twist stability test and estimate, seem more important.
At present, when stable to the twist of estimating the rear yarn of dead twist, mainly contain twist degree of stability method and dead twist rate method.
(1) twist degree of stability method: holding length is L
0The two ends of yarn, an end is fixed, and the other end is close to one section fixing translation, and the distance at two ends was L when yarn began to twist together, and twist degree of stability is expressed as P=(1-L/ L
0) * 100%.This kind method of testing adopts hand to survey method usually, has many defectives, as: because of the point-to-point speed poor controllability of movable terminal, yarn begins to reverse constantly difficult accurately definite; Before the yarn test pre-tension be affected by human factors larger, test result repeatable relatively poor.(2) dead twist rate method is called again twist coefficient of stabilization method or Snarl index method, the former ZBW 04001-1989 of China textile industry standard FZ/T 01056-1999() its method of testing is described in detail.This kind method of testing also exists pre-tension to be affected by human factors greatly, and test result is repeatable poor, and this standard is now abrogated.
In actual production, when the twist stability of the weft yarn after the dead twist aftertreatment is measured, usually adopt the long yarn of the stretching 100cm of both hands, then slowly close to 20cm, observe the kink number of yarn, when the kink number is 3 ~ 5 when following, yarn meets the requirement of production after the dead twist.This kind method row simple to operate, easy, but pre-tension is thought that also factor affecting is larger, test result repeatable relatively poor.
In sum, all there are many defectives in existing twist stability test device or method of testing, as: test result is affected by human factors larger, the accuracy of test result, repeatability, and the contrast property between the different yarns is relatively poor.
