Understanding Red Kap Workwear Shirts

Red Kap workwear shirts, particularly the SP24 model, are designed for durability and functionality. These shirts are made from a 65% polyester and 35% cotton blend, providing a balance of comfort and resilience. The material is stain-resistant and features a wicking property, making it ideal for industrial environments such as garages and workshops. The shirts come in a variety of colors, including charcoal, light blue, and navy, and are available in sizes ranging from small to 6XL, accommodating a wide range of body types.

Preparing for Heat Pressing

Before diving into the heat pressing process, it's essential to gather the necessary tools and materials:

• Heat Press Machine: A reliable heat press, such as the 16x20 Prisma heat press, is crucial for achieving consistent results.
• Heat Press Pillow: This accessory helps protect the buttons on the shirt and ensures even pressure distribution.
• Heat Press Pad: A durable pad, like the one from Essential Weare, can provide additional protection and stability.
• Heat Resistant Tape: This tape secures the transfer in place during pressing.
• Ruler and Alignment Tools: These help ensure precise placement of the design.

Step-by-Step Heat Pressing Process

• Pre-Press the Garment: Begin by pre-pressing the shirt for a few seconds to remove any moisture and wrinkles. This step is crucial for ensuring a smooth surface for the transfer.
• Adjust Heat Press Settings: Set your heat press to the appropriate temperature and pressure settings. For polyester-cotton blends, a temperature of around 300°F to 350°F and medium pressure is recommended.
• Position the Heat Press Pillow: Insert the heat press pillow under the area to be pressed. This will protect the buttons and seams from damage.
• Align the Transfer: Fold the transfer in half to find the center, then align it with the center of the shirt. Use a ruler to ensure the design is positioned correctly, typically about half an inch above the pocket for front designs.
• Secure with Heat Resistant Tape: Once aligned, secure the transfer with heat resistant tape to prevent it from shifting during pressing.
• Press the Design: Lower the heat press and apply pressure for the recommended time, usually around 15 to 20 seconds. Ensure the pressure is firm enough to transfer the design without damaging the shirt.
• Cool and Peel: Allow the shirt to cool slightly before peeling off the transfer paper. This helps ensure the design adheres properly to the fabric.
• Repeat for Back Design: If applying a design to the back, repeat the process, adjusting the size of the transfer as needed for larger shirt sizes.

Tips for Optimal Results

• Pressure Adjustment: When using a heat press pillow, adjust the pressure settings to accommodate the added thickness. The pressure should be firm but not excessive, to avoid damaging the shirt or transfer.
• Test Press: Always perform a test press on a small area or a sample shirt to ensure the settings are correct and the design adheres well.
• Use of Teflon Sheets: Place a Teflon sheet over the transfer to protect the fabric from direct heat and prevent scorching.
