5D×38mm Acrylic Fiber Raw White Semi-Dull Soft Finish Crimped Synthetic Fiber

Product Specification

5D×38mm Acrylic Fiber Raw White Semi-Dull Soft Finish Crimped Synthetic Fiber for Consistent Dyeing Results

Product Description:

Our premium 5 Denier × 38mm Acrylic Fiber is a high-performance synthetic staple fiber designed for superior softness, bulkiness, and textile versatility. Featuring a raw white semi-dull appearance with a soft finish and crimped structure, this fiber is ideal for applications requiring luxurious hand feel, excellent dyeability, and thermal insulation properties.

How is it Made?

Acrylic fiber is not grown or found in nature; it is engineered in a chemical plant. The process is called polymerization:

1. Raw Materials: It starts with fossil fuels, primarily petroleum or coal. Through chemical processes, these are converted into monomers (single molecules) of acrylonitrile.

2. Creating the Polymer: These acrylonitrile monomers are then combined (polymerized) to form long chains of a polymer called polyacrylonitrile (PAN). This is the base plastic for the fiber.

3. Spinning into Fiber: The PAN polymer is dissolved in a powerful solvent to create a thick, syrupy solution. This solution is then forced through a spinneret—a device with dozens of tiny holes, like a showerhead. As the streams of solution emerge, they harden into solid filaments of fiber.

4. Finishing: These continuous filaments are then stretched to increase strength and alignment, washed, dried, and crimped (given a wavy texture) to make them feel more like natural wool. Finally, they are cut into short staple lengths to be spun into yarn.

Key Features:

✔ Optimal Dimensions: 5 Denier thickness × 38mm staple length for balanced strength and processability
✔ Premium Aesthetics: Raw white base with semi-dull luster for consistent dyeing results
✔ Enhanced Comfort: Specially engineered soft finish for skin-friendly applications
✔ Functional Crimp: Permanent 3D crimp improves fiber cohesion and loftiness
✔ Exceptional Thermal Properties: Low thermal conductivity for warmth retention

Common Uses

Acrylic fiber is incredibly versatile and found in many products:

• Apparel: Sweaters, hats, scarves, gloves, fleece wear, athleticwear, and linings for boots and jackets.

• Home Furnishings: Blankets, upholstery fabrics, carpets, and area rugs. Its durability and colorfastness make it ideal for these uses.

• Craft Yarn: It is the most popular type of yarn for knitting and crocheting due to its affordability, wide color selection, and easy care.

• Industrial Uses: Used in awning fabrics, vehicle covers, and as a precursor for manufacturing carbon fiber.

Care Instructions

• Washing: Typically machine washable in cool or warm water. Use a gentle cycle.

• Drying: Tumble dry on low heat. High heat can cause melting, stretching, or permanent wrinkling.

• Ironing: If needed, use a very cool iron with a press cloth. Never use a hot iron directly on acrylic fabric.

• Storage: Resistant to moths, so no special storage is needed.
