Attaching Cloth Straps To Plastic: Best Practices

how to attach cloth straps to plastic

There are several ways to attach cloth straps to plastic. If the cloth strap is being attached to plastic armour, it is recommended to use a strong adhesive such as cyanoacrylate glue, E6000, epoxy resin, or Shoe Goo. For nylon straps, it is important to scuff the surface of the plastic and work the glue into the fibres of the strap. If the cloth strap is being attached to a plastic ring on a garment, it can be secured with a safety pin or sewn directly to the fabric loops. Alternatively, the plastic ring can be removed and the straps can be tied together or to a ribbon.

Using glue to attach cloth straps to plastic

When attaching cloth straps to plastic, it is important to consider the type of plastic and cloth involved, as some glues may not be suitable for certain materials. For example, super glue can eat through nylon, and some glues can make fabrics brittle and prone to breaking.

If you are attaching nylon straps to ABS plastic, one option is to use cyanoacrylate (CA) glue. This glue has been reported to hold straps in place for years. To use this method, scuff the surface of the plastic with low-grit sandpaper (80-100 grit), then wipe it with isopropyl or ethanol alcohol to remove any loose particles. Next, apply the glue to the scuffed surface, ensuring it gets into the scratches. Finally, press the nylon strap into the glue, being careful not to disturb the glue's bond as it dries.

For elastic straps, some people recommend using super glue, as it soaks into the fibres. To use this method, apply the super glue to the plastic surface, then clamp the elastic strap in place while the glue dries to promote adhesion. However, be aware that super glue may not be suitable for nylon straps, as it can eat through the material.

If you are looking for a more flexible option, E6000 or Shoe Goo are good choices. These glues remain flexible after drying, allowing both surfaces to flex at different degrees. To use these glues, first, press the glue into the fibres of the strapping, then apply glue to the plastic surface and press the two surfaces together.

For higher-temperature plastics, hot-melt glue can be used cautiously. Hot glue can be effective for nylon straps, as the heat slightly melts the surface of the nylon, welding the two materials together. However, added heat can reactivate the glue, causing the straps to peel away, so keep this in mind if you live in a hot climate or plan to wear the item in warm conditions.

When gluing cloth to plastic, it is important to maximise the surface area of the glue to create a strong bond. Consider gluing additional pieces to the plastic to increase the surface area available for bonding. Additionally, some glues, such as contact cement, produce harmful fumes, so always use a mask and ensure the area is well-ventilated when working with these products.

Scuffing the plastic surface before gluing

Scuffing the plastic surface creates a rough surface that the glue can grip onto, increasing the bond between the plastic and the glue, and making it stronger and more durable. This is a crucial step in preparing plastic for glue.

To scuff the surface of the plastic, you can use sandpaper or a scouring pad to lightly scuff the surface. You should use low-grit sandpaper (80-100 grit) to scuff the surface. After scuffing, you should wipe the surface with alcohol (isopropyl or ethanol) to remove all loose particles.

It is important to note that not all plastics are the same, and some may require additional cleaning steps or special treatment. For example, if the plastic surface has wax or silicone, it may need to be sanded or wiped with rubbing alcohol to improve adhesion. Therefore, it is essential to determine the type of plastic you are working with and choose the appropriate cleaning and scuffing methods.

Once the plastic surface has been scuffed and cleaned, you can move on to the next step of gluing the cloth straps to the plastic. It is crucial to choose the right type of glue and follow the manufacturer's instructions for the best results.

Sewing the cloth straps to fabric loops

Sewing cloth straps to fabric loops is a simple and effective way to attach straps to plastic. This method is ideal for clothing items such as dresses or tops with plastic rings or loops that connect the straps to the garment. Here is a step-by-step guide to sewing cloth straps to fabric loops:

Prepare the Straps and Loops

Begin by cutting the plastic rings or loops that originally connected the straps to the fabric. This will create two separate pieces: the cloth strap and the fabric loop. If the fabric loop is attached to the garment, carefully detach it to create a clean working area.

Pin the Straps and Loops Together

Take the cloth strap and fabric loop and pin them together. Ensure that the ends of the cloth strap are securely fastened to the corresponding ends of the fabric loop. You can use sewing pins or clips to hold them together.

Sew the Straps and Loops

Using a needle and thread, start sewing along the pinned edge of the cloth strap and fabric loop. Use small, neat stitches that go through both layers of fabric. Sew all around the edge, ensuring that the stitches are tight and secure. Backstitch at the beginning and end of your sewing line to reinforce the stitching.

Knot and Finish

Once you have sewn all around the edge, make a few small stitches in the same place to secure the thread. Then, tie a knot close to the fabric to ensure that the thread does not come loose. Trim any excess thread, leaving a small tail that can be tucked into the layers of fabric.

Repeat for the Other Strap

If your garment has two straps, repeat the same process for the other side, ensuring that the length and placement of the straps match.

By following these steps, you can securely attach cloth straps to fabric loops, creating a durable and adjustable connection. This method avoids the use of adhesives, which may not be suitable for certain types of fabric and plastic. Sewing the cloth straps to fabric loops provides a neat and functional finish to your garment.

Pinning the cloth straps to the plastic

Pinning cloth straps to plastic can be a great no-sew method for attaching straps to plastic or for making a garment with plastic straps easier to wear and hang. This method is especially useful for garments that are strapless, one-shouldered, or have spaghetti straps.

To start, lay the garment flat and smooth the strap along the inside of the garment. Then, secure the bottom of the strap to the garment with a pin. A safety pin is a good option for this, as it will be easy to close and open when you need to remove the pin. You can also use a brooch or decorative pin for a more ornate look. If you are pinning a cloth strap to plastic armour, you may want to use a stronger pin, such as a hat pin, and consider combining this method with glue for added security.

When you are wearing the garment, the pin will be hidden from view, and the strap will stay in place. This method also works well for hanging garments with plastic straps, as the strap can be pinned to the inside of the garment and then used to hang it up. This prevents the plastic strap from hanging out of the armhole or the top of the garment, which can be unsightly.

In addition to pinning, there are other ways to attach cloth straps to plastic. For plastic armour, using an adhesive such as glue may be a better option. It is important to consider the type of plastic and fabric being used, as some adhesives may not work on certain plastics, and some may make the fabric brittle. For example, super glue can eat through nylon, and epoxy glues can make fabric brittle. Shoe Goo (E6000) is a flexible adhesive that works well with strapping and allows both surfaces to flex at different degrees. It is also important to scuff the surface of the plastic and work the glue into the scuffed surface and the fibres of the strap.

Clamping cloth straps to plastic while glue dries

Once you have identified the plastic type, choose an appropriate glue. For nylon straps, a two-part epoxy glue is recommended, especially for ABS and HIPS plastics. Sand down the contact area well to create a rough surface for better adhesion. If using elastic straps, some prefer super glue as it soaks into the fibres. However, be cautious as super glue may eat through certain fabrics like nylon. An alternative to super glue is E6000 (Shoe Goo), which has a longer cure time of 24 hours but provides a strong, flexible bond.

Before gluing, scuff the plastic surface with low-grit sandpaper (80-100 grit) to create a rough texture. Then, wipe the surface with isopropyl or ethanol alcohol to remove any loose particles. Next, apply the glue. Press the glue into the fibres of the strap, ensuring it penetrates the scuffed surface of the plastic. Work the glue into each scratch to maximise adhesion.

Finally, clamp the cloth strap to the plastic securely while the glue dries. Clamping will promote adhesion and ensure a strong bond. Be cautious when clamping, as some glues can soften certain plastics, leading to distortion. Allow the glue to cure for the recommended time, which may vary depending on the adhesive used.

By following these steps and allowing adequate curing time, you can effectively attach cloth straps to plastic using glue and clamps.
