83% Polyester, 17% Spandex BLACK INTERLOCK FABRIC

KF000755

Black Interlock Fabric (83% Polyester, 17% Spandex)

This Black Interlock Fabric is a double-knit textile engineered for balanced compression and thermal regulation. Comprising 83% Polyester and 17% Spandex, the fabric utilizes an interlock construction where two layers of jersey are knitted together, resulting in a smooth surface on both the interior and exterior. With a weight of 230 GSM and a width of 152 CM, it provides substantial density and opacity, preventing transparency during elongation. The mechanical structure of the interlock knit ensures that the fabric does not curl at the edges and maintains a consistent drape across large-scale garment panels.

Technical Specifications

Core Characteristics

• Double-Sided Smoothness: The interlock technique creates an identical finish on both sides, enhancing skin comfort and reducing friction.
• High Recovery Rate: The 17% Spandex ratio provides a high modulus of elasticity, ensuring the textile returns to its original dimensions after tension.
• Edge Stability: Unlike single jersey, this double-knit construction resists rolling, facilitating easier cutting and sewing processes.
• Non-Transparency: The 230 GSM density ensures a "squat-proof" rating for athletic applications, maintaining coverage under maximum stretch.

Performance Attributes

• Thermal Insulation: The trapped air layer between the two knit faces provides moderate heat retention suitable for transitional weather.
• Moisture Management: Synthetic fibers transport sweat away from the body to the outer surface for accelerated evaporation.
• Abrasion Resistance: The tight knit structure minimizes pilling and snagging during high-intensity physical contact.

Application Scenarios

• Activewear: Mid-weight leggings, compression tights, and training shorts.
• Team Sports: Professional jerseys and warm-up suits requiring structured flexibility.
• Outerwear: Base layers for winter sports and lightweight hoodies or jackets.
• Medical/Support: Orthopedic braces and compression sleeves where consistent pressure is required.

Storage and Handling Guidelines

• Laundering: Wash at 30°C with synthetic-safe detergents. Do not use bleach, as it degrades the spandex molecular structure.
• Drying: Tumble dry on a low-temperature cycle or air dry flat. Excessive heat can lead to permanent loss of elasticity.
• Ironing: Use a cool iron setting if necessary. A pressing cloth is recommended to prevent surface glazing.
• Storage: Keep rolls in a horizontal position to prevent distortion. Store in a cool, dark environment to protect the polyester fibers from long-term photo-degradation.
