What are the reasons for the poor effect of textile silicone oil?

Silicone oil is generally used as a softener, lubricant, waterproof agent, finishing agent, etc. for fabrics in the textile and clothing industry. In order to meet the high-end demand for textiles, silicone material manufacturers are also constantly developing silicone oil products that can be used in the same bath with various functional additives such as waterproofing agents, flame retardants, antistatic agents, and color fixatives, and have a good feel. In addition, in order to improve the performance of fabrics, there are also silicone products that can be used in the same bath with dyeing.

There are cool cotton silicone oils, silicone products that can improve the feel of fabrics, and silicone-based deepening agents that can give fabrics excellent deepening effects, good storage stability, no effect on color fastness, and good feel. In addition to being used as additives in textiles to achieve the functionalization of textiles, silicone products will also be applied to other fields in textiles.

However, there are many types of textile silicone softeners, and the effects are also very different. Even if the same effect is used on different fabrics, it is necessary to make a correct selection of textile silicone softeners. If used improperly, the effect of the fabric you want will not be achieved at best, and the fabric will be damaged in severe cases. So how should we choose textile silicone softeners? What are the reasons for the poor effects of textile silicone softeners with the same effect? How should we solve these problems? Let the editor solve them for you now.

When using textile silicone softeners, you will encounter problems such as decreased hydrophilicity of fabrics, dark spots, light spots, alkali spots, and silicone oil stains. The reason for the decrease in fabric hydrophilicity is generally due to the problem of the film structure used and the lack of water absorption genes after silicone oil film formation, as well as the closure of water absorption centers such as hydroxyl groups on cellulose fibers, carboxyl groups on wool, and amino groups, which cause decreased water absorption.

Its treatment method: Anionic, non-ionic films and hydrophilic silicone oils should be used as much as possible.

Causes of dark spots:

1. The oil stains on the fabrics were not removed during pretreatment, and the color of the oil stains was darker during dyeing.

2. Too much foam in the dye bath, the mixture of foam, flower sweaters, dyes, etc. is stained on the fabric.

3. Defoamer oil floats and causes dark oil spots.

4. Tar-like substances in the dye vat are stained on the fabric.

5. Dyes coagulate to form dark spots under different circumstances. 6. Excessive calcium and magnesium ions in the water combine with dyes and stain the fabric.
