Question

The process of joining the two layers of fabric using heat pressing in-order to retain the shape of the garment component is called

• A. Welding
• B. Fusing
• C. Reviting
• D. Molding

Hint:

• Fusing} in garment production is the process of attaching fusible interlining to fabric pieces using heat and pressure.
• Fusible interlining has a thermoplastic adhesive resin on one side.
• The heat and pressure melt the resin, causing it to bond the interlining to the fabric.
• Purpose of fusing: To provide stiffness, support, shape retention, and body to garment components like collars, cuffs, plackets, waistbands.
• This matches the description of using heat pressing to join layers and retain shape.

Answer 1

The Correct Option is B

The question describes a process of joining two layers of fabric using heat and pressure to retain the shape of a garment component. This often involves an interlining material. Let's analyze the options:

• (a) Welding (e.g., Ultrasonic welding, RF welding): Welding is a process of joining materials (often plastics or metals, but also some textiles, especially thermoplastics) by applying heat and/or pressure to cause them to fuse together at the seam line, often without additional material like thread. While heat and pressure are used, "welding" usually implies direct fusion of the fabric layers themselves, which is common for thermoplastics.
• (b) Fusing (Interlining Fusing): This is a very common process in garment manufacturing, especially for components like collars, cuffs, lapels, waistbands, and plackets. It involves attaching an interlining (a separate layer of fabric, often coated with a thermoplastic adhesive resin) to one or both layers of the main garment fabric. This is done by applying heat and pressure using a fusing press. The adhesive melts, flows, and then solidifies upon cooling, bonding the interlining to the fabric. Fusing provides stiffness, stability, shape retention, and improved appearance to the garment component. This perfectly matches the description "joining the two layers of fabric (main fabric + interlining) using heat pressing in-order to retain the shape".
• (c) Riveting: Riveting is a mechanical fastening method using rivets (small metal pins or bolts) to join materials, typically metal sheets, leather, or heavy-duty fabrics like denim (e.g., rivets on jean pockets). It does not primarily use heat pressing for adhesion.
• (d) Molding: Molding involves shaping a material (often thermoplastic or thermosetting polymers, or sometimes fabrics treated with resins) into a three-dimensional form using a mold, typically with heat and pressure. While it uses heat and pressure and retains shape, it's about shaping a single material or component into a 3D form (e.g., bra cups, shoulder pads), not necessarily "joining two layers of fabric" in the way fusing does with an interlining.

The process described – joining layers of fabric (typically fabric and interlining) with heat and pressure to provide shape retention – is best termed Fusing. \[ \boxed{\text{Fusing}} \]
