Self-dispersing amino silicone softener for polyester and polyester-cotton blends: LK-SD 329

Role of silicone softener in textile industries

In today’s fast-paced fashion industry, fabric finishing is as important as the designs, materials, and colours that define a garment. Textile manufacturers must utilize innovative silicone softener trends to meet the fashion market’s demands and adapt to the latest consumer needs.

Silicone softening treatment aims to create a soft fabric handle, enhancing processability and wearability, which are crucial for fabric purchase and saleability. Additionally, softeners improve technical properties such as reducing the coefficient of fiber-fiber friction, enhancing hydrophilicity and elasticity, and giving synthetic fibres a natural touch and comfort.

The performance of a softener is based on following criteria:

  • Hand feel/ handle
  • Whiteness or low yellowing tendency
  • Hydrophilic/hydrophobic character
  • High shear stability under application conditions such as exhaust process
  • Bath stability at higher temperatures & wide pH range

LK-SD 329: Concentrated micro amino silicone softener for polyester and polyester-cotton (PC) blend fabrics

Introducing LK-SD 329 is a self-dispersing micro-emulsion of amino silicone fluids, specifically designed to elevate the quality of polyester and polyester-cotton blend textiles. This innovative product is ideal for a wide range of fabric finishing applications, including:

  • Ladies’ ethnic wear: Saris, Kurtis, top, and dress materials
  • Men’s apparel: Formal and casual shirts, suiting, and t-shirts
  • Home textiles: Bed-sheet, curtains and pillow covers

Why choose LK-SD 329 for textile finishing?

Enhanced handle performance:

LK-SD 329 is modified premium self-dispersing amino silicone emulsion formulated from reactive amino silicone fluids. Amino-functional silicones are the class of silicones that lead the current softeners market. It imparting soft and luxurious hand feel or often called as supersoft handle.

The silicone backbone gives fabrics a soft, smooth and slippery texture to fabrics, while the modified amine groups create strong interactions with the fibres and make fabric surface softer and smoother in touch.

Self-dispersing property:

LK-SD 329 is formulated as concentrated micro emulsion product. Its higher solid content allows it to be used in both undiluted and diluted forms, helping to reduce application and transportation costs. This self-dispersing micro-emulsion easily disperses in water, without the need for emulsifiers, making the application process simple and more eco-friendly.

Wash durability:

LK-SD 329 is micro emulsion in nature allowed it to goes inside fabric and coats or lubricate well to the fibre surface. It is made up of some special blend of reactive and non-reactive silicone fluids. Reactive silicone fluids forms a strong bond with fabrics surface make it durable and maintains its softness after several washing cycles.

Low yellowing tendency:

During LK-SD 329 innovative formulation, a special care taken of amino group that does not causing yellowness to applied textiles.

Application Process:

It is unique formulation makes it’s highly dilution stable finish bath. It is shear stable and sustains at higher temperature up to 60 °C. It has wide range pH stability from 5 to 9. It is used in application process such as padding, dipping, tumble wash and exhaust.

Dosages:

The optimum dosage varies based on the desired softness, type of fabrics, size of fabrics and finishing conditions.

  1. Pad-dry cure process: Dosages: 15-20 gpl (30% diluted emulsion)
  2. Exhaustion Process: Dosages: 0.5 -0.75 % (As received emulsion)

Case study: LK-SD 329 Silicone softener applied on different types of fabrics

We would like to share the results of LK-SD 329, a premium silicone softener that was applied to various fabric types, including polyester and polyester-cotton blends, using a 15 gpl concentration of 30% diluted emulsion with the pad-dry-cure process.

Polyester: The fabric showed remarkable improvements in softness, smoothness, and inner surface feel. A slight enhancement in slipperiness and bounciness provided a balanced, luxurious finish.

Polyester-Cotton Blend: This fabric benefited from enhanced softness and smoothness, coupled with an improved inner surface feel. The treatment provided a refined touch while maintaining comfort.

LK-SD 329 successfully elevated the hand feel of polyester and polyester-cotton fabric, making it ideal for a wide range of textile applications. Treatment provided a superior finish, boosting softness and smoothness while ensuring long-lasting performance.
