At SKF POLYTEX, we manufacture high-quality polyester knitted fabrics using different types of yarns to meet various industry needs. The choice of yarn impacts fabric texture, durability, stretch, and overall performance. Below is a breakdown of the most commonly used polyester yarns in knitting.

FDY and DTY Yarn

DTY (Draw Textured Yarn) – Soft & Stretchy DTY is a crimped, textured polyester yarn that has a slightly stretchy feel. It’s made by twisting and drawing polyester filaments, which gives the fabric a soft and breathable finish. 🔹 Why use DTY? ✔ Feels soft and comfortable ✔ Wrinkle-resistant and lightweight ✔ Works great with spandex for extra stretch 🔹 Where is it used? Sportswear, gym wear, casual wear Available in Micro DTY (softer & finer) and Dull DTY (matte finish)
FDY (Fully Drawn Yarn) – Smooth & Durable FDY is a smooth and continuous filament yarn with a glossy or matte finish. Unlike DTY, it has no crimp or texture, making it perfect for fabrics that need a sleek look. 🔹 Why use FDY? ✔ High durability and strength ✔ Smooth and uniform texture ✔ Ideal for lightweight and sheer fabrics 🔹 Where is it used? Polyester interlock, micro meshes, sublimation fabrics FDY Micro is used for soft & light fabrics like Micro Speedo FDY Dull gives a matte finish for a premium feel

Micro & Dull Polyester Yarns

Light or Matte, Your Choice Micro Polyester yarns have extra-fine filaments, making fabrics soft, lightweight, and breathable—perfect for sports jerseys and sublimation fabrics like Micro Speedo. Dull Polyester yarns, on the other hand, create a matte, luxurious feel, which is often used for high-end sportswear and fleece fabrics like Cationic Speedo. 🔹 Where is it used? Micro polyester: Breathable sportswear & sublimation fabrics Dull polyester: Premium gym wear & soft-textured fabrics

Denier & Filament Count – Why They Matter

Denier (D) refers to the thickness of the fiber, while Filament count (F) tells us how many strands are twisted together to make the yarn. 🔹 Examples of Denier & Filament Counts: 75D/72F → Soft & fine (lightweight, breathable fabrics) 150D/48F → Thicker & more durable (mid-weight sportswear) 300D/96F → Heavy-duty (fleece, warm fabric, or gloves) 🔹 Where is it used? Low denier (50D-75D) → Lightweight, breathable fabrics High denier (150D-300D) → Thicker, more durable fabrics

Spandex Yarn (Lycra Blend) – Stretch & Comfort

Spandex (also known as Lycra) is blended with polyester to add elasticity and improve fabric recovery. This prevents the fabric from sagging and makes it ideal for activewear. 🔹 Why use spandex blends? ✔ Gives fabric flexibility and stretch ✔ Makes garments comfortable to wear ✔ Helps maintain shape over time 🔹 Where is it used? Micro Interlock Lycra (Lycra Jersey) – Sublimation & sportswear Double Knit Lycra (Scuba) – Thick, structured gym wear Lycra Fleece (Scuba Fleece) – Winter sportswear & gloves

CDP (Cationic Dyeable Polyester) & Dyed Yarn (Pre-Dyed Polyester Yarns

CDP is a special type of polyester that can be dyed with both polyester and cationic dyes, creating unique two-tone and heather effects. ✅ Perfect for dual-tone fabrics ✅ Soft and premium feel ✅ Used in sportswear and fashion fabrics Best used in: CDP Cationic Mesh (Cationic Jali) for textured, breathable jerseys CDP Cationic Speedo (Cationic Fleece) for soft, high-end sportswear,
Unlike fabrics that are dyed after knitting, Dyed Yarns are colored before the knitting process. This helps create deeper, richer colors with better colorfastness. ✅ More vibrant and consistent color ✅ Resistant to fading and washing ✅ Great for fashion and performance fabrics Best used in: Custom sportswear fabrics, premium gym wear, and colored polyester blends

Yarn Blends – Mixing for the Best Properties

Sometimes, we blend polyester with other fibers like spandex or CDP (Cationic) to create custom fabric features. Blends give us the flexibility to tailor fabrics to exact needs, like specific stretch, color effects, or softness. Why We Use It: Polyester + Spandex gives fabrics more flexibility CDP (Cationic) + Polyester allows for unique dye effects that make the fabric stand out. Blends with Micro & Dull polyester help create soft, breathable fabrics with different textures. Best For: Sportswear and activewear with enhanced stretch or special dye effects like Cationic Mesh

Recycled Polyester Yarn (Eco-Friendly Option)

What It Is: Made from recycled plastic bottles, recycled polyester offers a more sustainable option for eco-conscious fashion. It has the same strength and durability as virgin polyester, but it’s better for the planet. 🔹 Why use recycled polyester? ✔ Helps reduce plastic waste ✔ Maintains strength and durability ✔ A sustainable option for eco-conscious brands 🔹 Where is it used? Sustainable sportswear & activewear
