Precautions for using amino silicone oil as a textile auxiliaries

Hits: 817 img

When using amino silicone oil as a textile auxiliaries, you need to pay attention to the following aspects:

Control dosage: Make sure that the dosage of amino silicone oil is within a reasonable range. For example, the dosage of amino silicone oil with a solid content of 20% is generally between 1.5% and 3% (O.W.F). Excessive dosage will not further increase the softness of the fabric, but may cause waste or other adverse effects.

Avoid sticking to the roller: For high-speed setting machines, such as when processing thin fabrics (such as chiffon, imitation silk, etc.), special attention should be paid to the permeability of amino silicone oil. Ordinary silicone oil has poor permeability and is prone to sticking to the roller. Therefore, when using it, the working fluid in the rolling tank needs to be replaced regularly and the rollers need to be cleaned frequently.

pH value control: When dipping or rolling the working fluid, the pH value should be controlled between 5.5 and 6, which helps to improve the softness, drape and elasticity of the fabric.

Dealing with alkaline problems: Ordinary silicone oil is not alkali-resistant, so if the fabric is alkaline, it needs to be treated before finishing to avoid silicone oil demulsification under alkaline conditions.

Cleaning and anti-sticking: When dealing with fabrics containing short fibers, pay attention to cleaning to prevent the short fibers from sticking to the silicone oil and forming sticky rollers or silicone spots. Cleaning work must be done before driving, and loose hair must be cleaned in time.

Temperature control: When using amino silicone oil, the temperature should be controlled between 30 and 40°C, generally not exceeding 50 to 60°C. Although the temperature has no obvious effect on the softness and smoothness of the hand, when the temperature is too high, the elasticity changes greatly, and amino silicone oil is prone to sticking to the roller and demulsification.

In addition, since the amino silicone oil emulsion may cause sticking to the roller if it is used for too long, it should be cleaned regularly and the roller should be scrubbed with a degreaser or detergent. In short, only by strictly following these precautions can the best effect of amino silicone oil in textile auxiliaries be ensured.
