Embroidery accessories hot melt film, often referred to as embroidery backing or stabilizer, plays a crucial role in machine embroidery by providing support, stability, and structure to embroidered designs. The key characteristics and properties of hot melt film for embroidery accessories include:
Material Composition:
Hot melt film for embroidery is typically made of a synthetic material, such as polyester or polypropylene. These materials are chosen for their strength and stability when exposed to heat and moisture.
Adhesive Coating:
One side of the film is coated with a heat-activated adhesive that bonds the film to the fabric during the embroidery process. The adhesive layer must be strong enough to secure the film but not leave residue on the fabric after embroidery.
Thickness:
Hot melt film comes in various thicknesses or weights, typically measured in grams per square meter (gsm) or microns (μm). The choice of thickness depends on the fabric and the desired level of stability and support.
Tear-Away or Cut-Away:
Hot melt film can be categorized as tear-away or cut-away, depending on how it is removed after embroidery. Tear-away stabilizers are designed to be torn away from the fabric, leaving no remnants. Cut-away stabilizers are trimmed away from the fabric after embroidery and provide long-term support.
Stiffness and Rigidity:
Hot melt film varies in stiffness and rigidity. Some are designed to provide firm support for densely stitched designs, while others offer a softer hand for lightweight fabrics and delicate designs.
Heat Activation Temperature:
The adhesive on hot melt film is activated by heat, typically through the heat of the embroidery machine's needle or a separate heat source. The activation temperature should be compatible with the embroidery process.
Water Solubility:
Some hot melt films are water-soluble, meaning they dissolve in water after embroidery. This type of stabilizer is often used for lace or freestanding embroidery designs.
Tensile Strength:
Hot melt film should have sufficient tensile strength to withstand the forces generated during the embroidery process, ensuring that it remains intact and doesn't stretch or tear.
Color:
Hot melt film is typically available in white or translucent colors to minimize visibility on the fabric. The choice of color can be important when embroidering on light or dark fabrics.
Compatibility with Fabrics:
Hot melt film should be compatible with a wide range of fabric types, including cotton, polyester, denim, knits, and more. It should not negatively affect the drape or appearance of the fabric.
Ease of Removal:
Tear-away stabilizers should be easy to tear cleanly, leaving no remnants behind. Cut-away stabilizers should be easy to trim without fraying or leaving visible edges.
Environmental Considerations:
Some hot melt films are environmentally friendly and biodegradable, making them a sustainable choice for eco-conscious embroiderers.
Packaging:
Hot melt film is often available in rolls or sheets. Packaging should protect the film from moisture and other environmental factors that could affect its performance.
Embroidery accessories hot melt film is an essential component in machine embroidery, providing stability and support to ensure that embroidered designs are of high quality and durability. The choice of hot melt film depends on the specific embroidery project, fabric type, and desired results.
