Whether the quality of splicing passes, first of all depends on the user's acceptance of the product should be based on user needs assessment criteria. For example, the user requests that the 20 kg fabric side should not be more than 10 pieces of rough air laid knuckles (up to the slub level of + 40%) and the thin air knot (up to a level of detail of -50%). Therefore, in the development of splicing operation requirements, requiring each shift test workers twist check. Each car evenly drawn 10, each spindle take 2 twist, respectively, the original yarn strength, splicing strength, splicing appearance test. Strong splicing less than 85% strength of the original yarn, the sentence is unqualified, splicing the appearance of partial thick, thin, burr and other phenomena that sentenced to be unqualified. It is required to form a test cycle for all machines and perform a cyclic test on all single ingots. Once found a serious failure of a single spindle, should immediately notify the shop to do stop ingot processing. Each class calculates the splicing strength pass rate and splicing appearance pass rate of any one of the indicators is less than 80%, should be tested after spinning workshop. Each class of test personnel should also promptly send the test results through the form of reports to all relevant personnel in a timely manner so that they can timely repair unqualified twisted single ingots.
