Which Applications Are Best Suited for Polar Fleece Fabric in Garment and Textile Manufacturing?

Polar fleece fabric is a synthetic, brushed knit textile engineered for warmth, durability, and efficient mass production. Widely used across apparel, workwear, and home textile categories, this material has become a staple for manufacturers seeking reliable performance at scale. Polar fleece is generally less expensive than natural alternatives like wool, and is widely sold by the yard or in bulk by the roll for commercial buyers. It is known for exceptional warmth, breathability, and moisture resistance, and it resists wear, pilling, shrinking, and fading, making it long-lasting for outdoor use. Its versatility allows it to be used in base layers, blankets, and pet products.

This article is written for B2B buyers—garment manufacturers, workwear producers, wholesalers, and importers—who need to evaluate polar fleece for bulk sourcing decisions. We’ll cover composition, technical specifications, manufacturing processes, performance characteristics, and practical production considerations to help you find the right product for your requirements.

Overview of Polar Fleece Fabric

Polar fleece is a synthetic fabric constructed through circular or warp knitting, followed by heavy brushing on one or both sides to create a raised pile surface. This construction method produces a great fabric that delivers excellent thermal properties while remaining lightweight and easy to process in factory environments.

Technical Definition

From a textile engineering perspective, polar fleece begins as a polyester knit base—typically a double-sided knit structure—that undergoes mechanical brushing to extract fibers from the surface loops. This brushing creates the characteristic fluffy, plush appearance and traps air within the fabric structure, which provides insulation.

Standard Fiber Basis

The material is usually composed of 100% polyester, including both virgin polyester and recycled PET sourced from post-consumer materials like plastic bottles. This makes recycled fleece increasingly available for buyers with sustainability requirements or certification needs.

Common weight ranges for polar fleece span approximately 150–350 gsm, with variations designed for different end uses from lightweight linings to heavy outer mid-layers.

Key Performance Aspects for Manufacturing

MH, as a vertically integrated manufacturer, supplies polar fleece alongside related garment accessories and trims—including sewing thread, zippers, and interlining—enabling full-package sourcing for production programs.

Fiber Composition and Technical Specifications

Composition, weight, and width are critical parameters for industrial buyers evaluating polar fleece. These specifications directly impact garment performance, production efficiency, and final product positioning.

Typical Fiber Compositions

100% Polyester (Most Common)

• Standard construction for polar fleece

• Offers durability, colorfastness, and easy care properties

• Available in virgin and recycled polyester options

Polyester/Spandex Blends

• Typically 95/5 or 97/3 ratios

• Provides enhanced stretch and recovery for activewear applications

• Soft hand feel with improved body conformity

Recycled Polyester Options

• Supports sustainability certifications and brand requirements

• Performance comparable to virgin polyester when properly processed

• Growing availability for bulk orders

Standard Technical Ranges

Weight Selection by Garment Category

The GSM you select affects which product categories the fabric supports:

• Lightweight (150–180 gsm): Base layers, jacket linings, lightweight accessories

• Mid-weight (200–260 gsm): Casual jackets, pullovers, scarves, hats

• Heavy (280–350+ gsm): Workwear layers, outdoor jackets, blankets, throws

Quality Tolerances for Bulk Orders

Industrial buyers should specify and verify these tolerances:

• GSM variation: Typically ±5% from target weight

• Width variation: ±1–2 cm from stated width

• Color difference (ΔE): Usually ≤1.0 for good quality production

• Shrinkage rate: Commonly ≤3% after standard wash testing

MH can customize fiber type, GSM, and width according to buyer technical packs and end-use requirements, supporting both stock programs and custom development.

Manufacturing Process of Polar Fleece

The creation of polar fleece fabric is a multi-stage process designed to deliver a super soft, plush, and highly durable material suitable for a wide range of applications. It all begins with the production of polyester fibers, which can be either virgin or recycled. These fibers are then knitted—most commonly using circular or warp knitting—into a thick, double-sided fabric base. This knit structure is what gives polar fleece its signature warmth and flexibility.

Once the base fabric is formed, it undergoes a critical brushing stage. Specialized machines brush both sides of the fabric, raising the fibers to create the fluffy, soft texture that makes polar fleece so comfortable and highly breathable. This process also increases the fabric’s thickness and enhances its insulating properties, making it ideal for jackets, vests, blankets, and scarves.

To ensure the fleece remains looking great over time, anti pill treatments are applied during manufacturing. These treatments help prevent the formation of pills—small fiber balls that can appear on the surface after repeated use or washing—thus maintaining the fabric’s original appearance and feel. Additional finishing treatments may be used to impart water repellency, wrinkle resistance, or other performance characteristics, depending on the end-use requirements.

After finishing, the fleece fabric is carefully cut to the required dimensions and sewn into finished products. Throughout the process, rigorous quality checks are performed to monitor thickness, weight, and overall durability. Leading brands like Polartec utilize proprietary manufacturing techniques to produce fleece fabric with superior plushness, consistent thickness, and long-lasting performance, ensuring that every yard of fabric meets the highest standards for B2B buyers.
