How to use TPU elastic tape to shape knitwear

Knitted garments are favored by consumers for their softness, comfort, and breathability. However, knitted fabrics are prone to deformation during wear and washing, which affects the appearance and longevity of the garment. Using TPU tape is an effective solution to prevent deformation in knitted garments. TPU elastic tape have excellent elasticity, durability, and transparency, making them a popular choice for many high-end clothing brands.

 

1. Choosing the right TPU elastic tape

 

(1) Width: Select the appropriate width of the TPU tape according to the specific needs of the knitted garment. Common widths include 3mm, 5mm, and 10mm. The choice of width should consider the parts of the garment that need support and their stress distribution. For example, cuffs and hems usually require narrower elastic tape, while the waist and collar may need wider elastic tape.

 

(2) Thickness: The thickness of the TPU clear elastic tape is also important. Common thicknesses are 0.1mm, 0.15mm, and 0.2mm. The greater the thickness, the better the elasticity and durability of the elastic band, but it will also affect the comfort of the garment. Choose according to the specific application scenario to achieve the best balance.

 

(3) Quality: Choosing high-quality TPU elastic tape is crucial. High-quality TPU elastic tape have high transparency, are non-toxic, odorless, have good elasticity, and strong durability. It is recommended to choose TPU elastic tape produced by well-known brands such as BASF to ensure stable performance.

 

2. Using professional equipment to sew TPU elastic tape

 

(1) Sewing equipment: Use professional sewing equipment to sew the TPU clear elastic tape to the knitted fabric. Professional equipment ensures uniform stitching and a tight fit between the elastic band and the fabric, preventing the elastic band from falling off or loosening during use.

 

(2) Sewing methods: Choose the appropriate sewing method based on the style and design of the garment. Common sewing methods include straight stitching and zigzag stitching. Ensure that the stitches are evenly distributed and that the elastic band is flat and wrinkle-free to achieve the best support effect.

 

(3) Adjusting tension: Adjust the tension of the sewing machine appropriately during sewing to avoid the elastic band being too tight or too loose. An overly tight elastic band may cause garment deformation, while a loose elastic band may not provide enough support.

 

3. Proper placement of elastic tape

 

(1) Key areas: Place the TPU tape in areas that need extra support based on the garment's style. Common key areas include the collar, cuffs, hem, waist, and shoulders. These areas are prone to deformation during wear and washing, and adding TPU elastic tape can effectively prevent deformation.

 

(2) Even distribution: Ensure the elastic band is evenly distributed when placing it to avoid localized stress leading to deformation. Segmental sewing can be used to ensure the elastic band is evenly stressed in all areas.

 

(3) Concealed placement: To avoid affecting the appearance of the garment, the TPU elastic tape can be concealed. For example, sew the elastic band on the inner lining or inside the collar and cuffs to provide support without affecting the exterior.

 

4. Fitting, shaping, and adjusting

 

(1) Fitting test: Conduct fitting tests after sewing the TPU tape to check the suitability and comfort of the garment, especially the support effect of key areas. Ensure the elastic tape does not cause discomfort or affect the appearance during wear.

 

(2) Minor adjustments: Make minor adjustments to the position and tension of the TPU elastic tape based on fitting results. Ensure the elastic tape provides sufficient support without affecting the comfort and appearance of the garment.

 

(3) Multiple fittings: Perform multiple fittings before finalizing to ensure all performance indicators meet expectations. For key areas, different sewing methods and position adjustments can be used to find the best solution.

 

Using TPU elastic tape is an effective method to prevent deformation in knitted garments. By selecting the appropriate width and thickness, using professional equipment for sewing, properly placing the elastic tape, and conducting fitting tests and adjustments, the durability and appearance of knitted garments can be greatly improved. TPU elastic tape not only have excellent elasticity and durability but also offer transparency and environmental benefits, making them an indispensable material in modern clothing design. Proper use of TPU elastic tape can extend the life of garments and improve consumer satisfaction.
