Knitted interlining is applied in the garment manufacturing process to provide structure, support, and durability while maintaining flexibility and comfort. The application of knitted interlining involves several critical steps, including cutting, fusing, and sewing, which require precision and attention to detail to ensure the garment's functionality and aesthetic quality.
### 1. **Selection of Interlining**
The first step in applying knitted interlining is selecting the appropriate type based on the garment's fabric, design, and function. Factors such as the weight, stretch, and bonding method of the interlining must be carefully considered. Lightweight interlining is often chosen for delicate fabrics like silk, while
Knitted Interlining Manufacturers heavier options are suitable for more substantial fabrics like wool. The elasticity of the knitted interlining must complement the outer fabric to ensure it doesn't restrict movement.
### 2. **Cutting**
Once the appropriate knitted interlining is selected, it is cut to match the shape and size of the pattern pieces requiring support. The cutting process must be precise, as improper cutting can affect the garment's fit and appearance. Knitted interlinings are usually cut slightly smaller than the garment piece to avoid bulk in the seams. This step requires care to ensure that the interlining aligns perfectly with the fabric during fusing and sewing.
### 3. **Fusing Process**
Most knitted interlinings are fusible, meaning they have a layer of adhesive on one side that bonds to the garment fabric when heat and pressure are applied. The fusing process involves placing the adhesive side of the interlining against the wrong side of the fabric and applying heat using a pressing machine or iron. The temperature, pressure, and duration must be controlled to ensure a secure bond without damaging the fabric or the interlining.
- **Pressing Machines:** In mass production, industrial pressing machines are used to fuse interlining. These machines allow for even heat distribution and consistent pressure, ensuring a strong and uniform bond. They also speed up the process compared to manual methods.
- **Hand Ironing:** For smaller or more specialized production, hand ironing may be used, but it requires more skill to achieve consistent results.
### 4. **Sewing**
After fusing, the garment is assembled through sewing. The interlining is typically sewn together with the fabric during the construction of collars, cuffs, lapels, or waistbands. Since knitted interlining stretches, care must be taken during sewing to avoid puckering or misalignment, particularly in areas where movement is essential, such as shoulder seams or curved sections.
### 5. **Final Pressing and Quality Control**
Once the garment is assembled, a final pressing ensures the interlining lays flat and the fabric looks smooth. Quality control checks follow, focusing on the bond strength between the fabric and the interlining, as well as the garment's shape and structure. Any issues, such as lifting of the interlining or misshaped areas, are addressed before the garment is completed.
### Conclusion
Applying knitted interlining in the manufacturing process involves careful selection, cutting, fusing, and sewing to enhance the garment's performance, comfort, and durability. By following these steps, manufacturers can create garments with a balance of structure and flexibility, ensuring high-quality results.
