Color-Wise Process Loss Percentage in Textile Dyeing and Finishing
In textile manufacturing, particularly during dyeing and finishing, process loss is an inevitable factor that affects fabric weight and overall production yield. Process loss refers to the reduction in fabric weight due to various treatments, such as scouring, bleaching, dyeing, enzyme treatments, brushing, or finishing. The percentage of this loss varies significantly based on color, finishing techniques, and the type of fabric.
This article provides a detailed analysis of color-wise process loss percentages across different textile finishing processes, including enzyme wash, peach finish, and fleece treatments.
1. Process Loss Without Enzyme Treatment
When fabrics are dyed and finished without enzyme treatment, the average process loss remains moderate due to fewer abrasive and chemical treatments. The loss percentages are as follows:
White Shades: 8%
Black Shades: 6%
Other Color Shades: 7%
Yarn Dyed (Y/D): 3%
Grey Melange: 7%
2. Process Loss with Enzyme Treatment
Enzyme treatments, widely used for bio-polishing, enhance fabric smoothness and softness but lead to higher weight loss due to the removal of surface fibers. The color-wise process loss with enzyme treatment is:
White Shades: 11%
Black Shades: 9%
Other Color Shades: 10%
Yarn Dyed (Y/D): 5%
Grey Melange: 10%
3. Peach Finish Process Loss
The peach finish, which involves a soft brushing or sanding effect, results in a process loss similar to enzyme-treated fabrics. This finishing technique is popular for achieving a suede-like surface. The losses are:
White Shades: 11%
Black Shades: 9%
Other Color Shades: 10%
Yarn Dyed (Y/D): 5%
Grey Melange: 10%
4. Fleece without Brushing
Fleece fabrics that undergo dyeing and finishing without brushing have higher process loss due to their bulkier structure and heavier chemical absorption during wet processing. The color-wise losses are:
White Shades: 13%
Black Shades: 11%
Other Color Shades: 12%
Yarn Dyed (Y/D): 5%
Grey Melange: 12%
5. Fleece with Brushing
When brushing is introduced to fleece fabrics, the process loss increases further because of fiber removal during the brushing process, resulting in a softer and loftier surface. The losses are:
White Shades: 15%
Black Shades: 13%
Other Color Shades: 14%
Yarn Dyed (Y/D): 5%
Grey Melange: 14%
Conclusion
Understanding color-wise process loss is critical for accurate fabric cost calculation and production planning in textile manufacturing.
White fabrics consistently show the highest loss percentage due to the extensive bleaching and chemical treatments they undergo.
Yarn Dyed (Y/D) fabrics have the lowest loss, as they are pre-dyed before weaving or knitting, requiring minimal wet processing.
Enzyme and peach finishes contribute to moderate losses, while fleece with brushing shows the highest loss, reaching up to 15% in white shades.
Manufacturers can use this data to optimize finishing processes, control waste, and ensure accurate GSM (grams per square meter) targets after finishing.
