Tying Bowls: Reinforcement for Comfort and Support
Enhancing Stability and Safety:
Tying bowls is the process of reinforcing the cups and lower edge of the bra. Using a double-needle machine, we sew together the inner layer of soft woolen fabric with the outer layer of larger woolen fabric, adding a steel ring in between. This technique not only enhances the bra’s stability and support but also ensures that the woolen fabric lies comfortably against the skin, preventing the underwire from protruding and causing injury.
Attention to Detail:
- Stitching Precision: Ensure that the stitching is flat and even, with no skipped stitches. The double-needle stitches should be routed 1 mm from the edge.
- Symmetry and Consistency: The two sides of the woolen fabric must be of equal size, and the left and right parts of the lower edge should be symmetrical. The middle section should be aligned properly.
- Quality Checks: Fix the rubber bone of the lower cut securely, and ensure the size matches the standard size chart. Consistency in fabric color is also crucial.
Lagging Shoulder Straps: Form and Function
Combining Style and Comfort:
The next step involves combining the back of the bra with the shoulder straps to form a U-shape. This design not only enhances the aesthetic appeal but also prevents the shoulder straps from slipping off easily.
Sewing Techniques:
- Edge Sewing: Using a Renzi sewing machine, sew the edge cloth into the fabric at a depth of 5 mm. This ensures that the stitching is even and flat, preventing any thread breakage.
- Durability: The stitching must be strong and consistent to withstand daily wear and movement.
Locking Hooks: Precision and Safety
Securing the Fit:
The final step is to sew the hook and buckle onto the back of the bra. Depending on the number of hooks, this can be a two-row, three-row, or four-row configuration. Using a specialized sewing machine, the edge cloth of the buckle is sewn in at 7 mm, with the stitching 1 mm from the edge to ensure a secure fit.
Quality Control:
- Alignment: The middle of the back hook should be perfectly aligned with the mark, ensuring it matches the shape of the cup.
- Consistency: Check for any color differences or quality issues in the back buckle to maintain uniformity.
- Safety: Ensure that the stitching is secure and that there are no loose threads that could compromise the bra’s integrity.
Conclusion
The craftsmanship involved in making a bra is intricate and requires precision at every step. From reinforcing the bowls for added support to ensuring the shoulder straps stay in place and securing the hooks for a perfect fit, each step contributes to the overall comfort and durability of the bra. By mastering these techniques, we can create a product that not only looks great but also provides the necessary support and safety.
