Circular knitting cloth prevention crosspiece

Maturity is the key influence yarn quality: the structural characteristics of cotton fibers, affecting the quality of the yarn, the yarn from the most deadly defects, is woven into the fabric, the suction generated by the dyed color is uneven, the fabric surface from rungs, this defect in the whole cotton test project, not testing and unpredictable.

In the present, the textile industry, cotton yarn dyed to know the results, only the batch of yarn by weaving, dyeing, I discovered that the results do not yet have the instrument, the method can predict the situation. (And other issues arising from cross-therefore, it can tell) Fabric dyeing newcomer cross, of course, there are a number of reasons, exclude weaving, dyeing problems outside.

Many people say that the circular knitting fabric surface is difficult to distinguish from what the problem is caused by the cross, my approach is: yarn that loom large ones, assuming a 90-way, then we split out in the finished fabric surface 90 yarn, then each piece of paper yarn wound on a card, then 90 Sesha do card put in the lamp for color matching, the deep, the shallow, classification, such as color separation obviously, they cotton yarn by color ratio is uneven, nothing to do with weaving. Cotton yarn dyed uneven maximum extent because cotton fiber maturity differences, caused by the amount of color unevenness, different maturity of cotton fiber, yarn are different in proportion to the problems caused by the dye.

Establish standards archives: first establish a standard repository, including: A) the maturity of cotton fibers of various standard file that each micronaire standard pattern B) from a variety of cotton fiber cross pattern.

A. Each micronaire standard pattern: pumping a variety of common cotton, micronaire arrangement drawing their kind, including raw cotton, sliver and yarn (cotton micronaire value calculated according to the number of fibers containing yarn, compare the actual case).

B. cross from fiber pattern: collect all kinds of finished cloth from the cross, and then fold out from the horizontal part of the pattern made ​​of fiber, try to find out from the cross-fiber pattern in common, do the standard Sample. Sample comparison with the standard: to collect a large number of cotton fiber samples from a cross chart patterns contrast with micronaire, and then determine the maturity of cotton fiber really difficult to find since the vast majority of cotton fiber cross immature fibers, and query data , and micronaire cotton spinning before the test is also very different.

Try before dyeing to see the maturity of cotton fiber into yarn, and then assess the situation after staining, confirmed by long-term operation, summed up the successful examples, as the standard method of enterprises. For each feature and cotton fiber maturity, test items, in a variety of clear data, the idea of ​​cotton fiber, only made ​​with cotton and other processes, so that the yarn to the issues resolved in advance.

Sample questions:
General Cotton Mill, most have to do testing of cotton, cotton yarn work, but just look at the test values ​​are often unable to analyze cause of the problem is mainly different sampling conditions sample tests, failure to standard treatment, it becomes actual results do not meet, may require the implementation of national standards. The standards of the cotton fiber maturity and associated test methods listed in cotton, mainly so that we know the microscopic tests, using a variety of methods (methods can be customized), with each company’s equipment, create your own standard real samples Gallery (which may include the projects, where the related impact of cotton fiber maturity and quality of yarn), with improvements to predict and set the appropriate yarn and yarn allocation process.
