The production and processing of fabrics require a series of complex processes. Desizing is one of the most important processes. If the slurry is not removed cleanly, the fabric may become damaged after being made into clothes. There will be problems of color fading or color channeling, and the feel of the desized fabric is very poor, so the desizing result directly affects the quality of the fabric. So how to deal with the unclean desizing of the fabric?
Requires recycling and re-desizing
If If it is found that the fabric is not clean after desizing, it is necessary to recycle the fabric and desize it again. Make sure it is clean before using it to produce clothing or wholesale fabrics.
Recommended to pay attention to the use of reagents
When desizing fabrics, two reagents, refining agent and desizing agent, are used. For the first desizing, these two reagents should be used in proportion. However, for desizing again, it should be based on the desizing condition of the fabric. Decide which fabric to choose.
Choose a desizing agent according to the fabric
In order to avoid the situation of dirty desizing, the desizing should be selected according to the material of the fabric. It is more suitable to use refining agent for relatively light and thin fabrics such as silk, while desizing agent is preferred for cotton fabrics.
Reduce the concentration of desizing agent
Because the fabric has been desized once, the fabric itself does not contain a lot of pulp, so the concentration of the desizing agent should not be too high when desizing again, otherwise it will damage the fabric.
The rinsing process must be in place
After desizing, the fabric needs to be rinsed. Generally, a specific machine is used for rinsing. If you use a washing machine to rinse, sizing stains may remain on the fabric.
Storage after desizing
After rinsing, put it in the dryer to dry, because if it is dried naturally, it will be easily contaminated by dust in the air, which will affect the quality of the fabric.
