First, the color difference
The color difference as it is refers to the color difference between a dyed sample and a customer confirmed sample. The dyeing workshop must first carry out the proofing of large machines during production, and after the proofs are qualified, the normal production can be started. Under the machine color sample should be very close to the standard sample, but there should be room for change in the color of the dyed finished product after finishing, in particular, it should be noted that some colors by the special finishing shade changes will be more obvious. For the dyeing of paints, many customers require the effect of washing and fading. This requires that the dyeing machine be washed for the first time and the color after washing be observed.
Second, the edge of the color difference and the front mouth color difference
The chromatic aberration in the edge refers to the color difference between the left and right cloth and the middle of the cloth. When the dyeing machine is out of the cloth, the general merchandiser should sample three full-size pieces (top, middle and bottom) in each box and compare them with each other. Check and monitor the color of the edges. At the same time (dyeing workshop will require) to sample each box in order to discharge good or cut the sample cloth attached to the sample card, check and monitor the color difference before and after, in order to compare before and after the fluctuation of the color difference is within the normal allowable range, This can not only find the color difference before and after each box cloth, but also can see whether the whole batch of cloth before and after color, if found to have problems should also find out the reasons for the first time and make adjustments and processing.
Third, the physical quality of the cloth
The physical quality of the cloth refers to the visual perception of the uniformity, fullness, etc. of the cloth color. The dyeing machine cloth cannot have any streaks such as stains, uneven dyeing, white cores, and poor dyeing, especially for some fabrics. Lightweight fabrics and certain types of linen fabrics are more prone to such problems. After the problem is found, stop immediately and adjust the dyeing process until the physical quality of the dyed fabric reaches the customer's request.
Fourth, the fabric defect
The defects found on dyed fabrics may also be caused by the grey fabrics themselves. For example, the abnormal fibers found on dark fabrics (when dyed with cotton dyes) and the colored yarns on light-colored fabrics are gray fabrics. The flaws that they themselves bring, especially the abnormal fibers, can only be fully exposed after dyeing. In addition, some scratches on the cloth surface of the grey fabric and the aurora and bale marks can also be compared after dyeing. obvious.
The quality of the cloth under the machine is checked dynamically at the cloth exit of the machine table. Because the fabric running speed is fast (general speed is about 50mm/min), it is inevitable that the cloth inspection will be missed by naked eye inspection. This should be noticed.
