The article introduces a new method for treating weft yarn in color-woven fabrics. It involves three steps: dyeing the yarn, applying a liquid sizing agent, and drying it.
Let’s break it down:
Step 1: Dyeing the Yarn
First, we dye the yarn in the usual way.
Then, we add a softening agent and dye the yarn in a loop for 5-10 minutes.
Step 2: Liquid Sizing
Next, we apply a liquid-sizing material to the yarn in a loop for 5-10 minutes.
The liquid sizing can be either a 25% solid acrylic emulsion or a 100g/L PVA solution.
If we use the acrylic emulsion, the ratio of the liquid sizing to the yarn is 20-50:1000.
If we use the PVA solution, the ratio is 10-20:1000.
Step 3: Drying
Finally, we dry the yarn after sizing.
Advantages
By using our method, we’ve seen a 10% increase in yarn strength and a 30% reduction in fuzziness.
This not only improves the efficiency of weaving but also enhances the appearance of the fabric.
