Silicone oil is a synthetic lubricant that has gained popularity in the textile industry due to its excellent lubrication properties, high thermal stability, and low surface tension. It can be used on a wide range of fabrics, including cotton. Here are some of the classifications and applications of silicone oil for cotton.
1. Smooth block silicone oil
Smooth block silicone oil is a type of silicone oil that has been specially designed for use on cotton fabrics. It is a non-reactive, non-toxic, and non-corrosive lubricant that is commonly used in the textile industry to improve the overall quality and performance of cotton fabrics. The unique feature of smooth block silicone oil is that it is a block copolymer of silicone and polyether, which means it has both hydrophobic and hydrophilic properties.
When applied to cotton fabrics, smooth block silicone oil creates a smooth and even surface that reduces friction and abrasion between fibers. This, in turn, improves the fabric's softness, drape, and durability. Additionally, smooth block silicone oil has excellent water repellency, which makes it useful for outdoor clothing and rainwear.
Smooth block silicone oil can be applied to cotton fabrics using a variety of methods, including padding, exhaustion, and spray. The application method depends on the desired level of lubrication and the specific textile application. For example, if a cotton fabric requires heavy-duty lubrication, a high-viscosity smooth block silicone oil can be applied using the padding method.
2. Hydrophilic silicone oil
The unique feature of hydrophilic silicone oil is that it has a polar functional group, which makes it highly attracted to water molecules.
When applied to cotton fabrics, hydrophilic silicone oil creates a hydrophilic coating on the fabric's surface, which enhances its water absorbency and wicking properties. This is particularly useful for cotton fabrics that are used in sportswear and activewear, as it helps to keep the wearer dry and comfortable during physical activity.
Hydrophilic silicone oil can be applied to cotton fabrics using a variety of methods, including padding, exhaustion, and spray. The application method depends on the desired level of lubrication and the specific textile application. For example, if a cotton fabric requires high levels of water absorbency, a high-viscosity hydrophilic silicone oil can be applied using the exhaustion method.
Padding: In this method, the cotton fabric is passed through a bath containing silicone oil. The excess oil is then squeezed out, and the fabric is dried.
Exhaustion: In this method, the silicone oil is added to the dyeing bath, and the cotton fabric is dyed and lubricated simultaneously.
Spray: In this method, the silicone oil is sprayed onto the cotton fabric, and then the fabric is dried.
Softening: Silicone oil can be used to soften cotton fabrics, making them more comfortable to wear.
Antistatic: Silicone oil can be used as an antistatic agent on cotton fabrics, reducing the buildup of static electricity.
Water repellency: Silicone oil can be used to make cotton fabrics water-repellent, which is useful for outdoor clothing.
Wrinkle resistance: Silicone oil can be used to improve the wrinkle resistance of cotton fabrics, reducing the need for ironing.
