Introduction:
Dyeing and printing are generally tinted to make fabric and accessories becomes attractive or for useful reasons to apply. Finishing is the last stage of dyeing and printing. Better finishing process can reduce most of the defects of dyeing and printing process in textile industry. Today I would like to talk about the major defects of dyeing, printing and finishing.
Major Defects of Dyeing Printing and Finishing:
In the textile industry, the manufacturing process of fabric there are different kinds of defects are found. The defects of dyeing, printing and finishing are such as back fabric seam impression, bleeding, color out, color smear, crease mark, crease streak, dye streak in printing, mottled, printing machine stop, and print out of repair etc.
Major Defects of Dyeing Printing and Finishing
Major defects of dyeing, printing and finishing are given below-
| S/L | Defects | Explanation |
| 01 | Back Fabric Seam Impression | Backing fabric is used to cushion fabric during printing. If there is a joining seam in the backing fabric, an impression will result on printed fabric. |
| 02 | Bleeding | Caused by non-fixed dye or ink. |
| 03 | Color Out | Caused by color running low in reservoir on printing machine. |
| 04 | Color Smear | Caused by color being smeared during printing. |
| 05 | Crease Mark | Caused by fabric folds in the finishing process resulting increase marks. |
| 06 | Crease Streak | Caused by creased fabric passing through squeeze rollers in dyeing on tubular knits. |
| 07 | Dye Streak in Printing | Caused by a damaged doctor blade or blade not being cleaned properly resulting in a long streak on the fabric. |
| 08 | Mottled | Caused by unevenly applying color during printing. |
| 09 | Printing Machine Stop | Caused by printing machine stopping. Results in dye or ink being smudged along the width of fabric. |
| 10 | Print Out Of Repair | Caused by print rollers not being synchronized properly. Results in miss-registration. |
| 11 | Water Spots | Caused by wet fabric being left for too long before drying. Can result in color migration leaving blotches. |
