Nylon cords are suitable for outdoor applications, garments, and accessories. They are also used in crafts and household applications. Nylon elastic cords can be more expensive than other materials but offer excellent durability and longevity.

Design of bulk elastic cords

Elastic cords are available in different designs according to the needs of applications. Here are some of the common design elements:

• Materials

  The cord may be manufactured from different materials depending on their strength and durability requirements. The materials include rubbers for thick cords that require stretch and durability. Durable plastic materials like polypropylene are used for their strength and resistance to environmental factors. Nylon is used for its strength and flexibility, with some cords having a nylon sheath for added protection. Silicone provides a good stretch and retains properties over time, so it is suitable for various applications, including medical ones. The metallic wires provide strength and are used in applications where strong support is required.

• Thickness and Width

  The thickness and width of the elastic cords vary depending on the application requirements. The thin cords are lightweight and flexible for securing lightweight items. The medium cords provide versatility in applications and a balance of strength and flexibility. The thick cords offer strength and durability for heavy-duty applications.

• Configuration

  Single-strand cords are lightweight and flexible for securing items. The double-strand cords provide added strength and security and are suitable for outdoor applications. The multi-strand configurations provide flexibility and durability for various indoor applications.

• End Treatments

  The end treatments of the elastic cords are designed for secure attachment. The cord ends are melted to prevent fraying and provide a simple treatment. Plastic or metal ferrules provide secure and adjustable attachment. Knots or loops are easy to make and provide simple attachment methods. The hooks and clips offer quick and secure attachment.

• Features

  Some of the additional features that may be present in elastic cords include UV resistance to withstand sunlight exposure. The cords may be treated for mold and mildew resistance to prevent growth in damp environments. The cords may also have fire retardant properties to reduce the risk of fire spread. The cords may have reflectivity to enhance visibility in low-light conditions.

Wearing/Matching suggestions of bulk elastic cord

Matching and wearing the bulk elastic cord can vary depending on the project and the type of fabric. Here are some general tips:

• General Tips:

  When buying elastic cords in bulk, it's important to consider the thickness of the cord. The thickness will determine how much stretch the cord has and how it will fit through different types of fabrics. For lightweight fabrics like chiffon or georgette, a thin elastic cord (1/8 inch or 3 mm) works well. For medium-weight fabrics like cotton or silk, a cord of 1/4 inch or 6 mm is ideal. Heavyweight fabrics like denim or canvas require a thick cord of 1/2 inch or 12 mm. Always pre-wash your fabrics before cutting and sewing to avoid shrinkage later on.

  When cutting the elastic cord, leave a little extra length to allow for mistakes or stretching that may occur during the process. A good rule of thumb is to add 1 inch for every 10 inches of the cord you're cutting. Use sharp scissors or a rotary cutter to get a clean cut without fraying the ends. If you notice any fraying, seal the ends with a lighter or glue to make it easier to thread through the fabric.

• For Drawstring Hoods:

  To make a drawstring hood, cut a piece of elastic cord to the desired length, usually 2-3 inches longer than the width of the hood opening. Use a safety pin or a drawstring threader to pass the cord through the hood's casing. Adjust the length evenly on both sides and secure with knots at the ends. Add plastic or metal toggles to hold the drawstring in place.

• For Wristbands:

  For a snug fit, cut the elastic cord to fit around the wrist plus 1 inch for overlap. Use a small amount of glue to secure the ends together, or thread the cord through a buttonhole and tie a decorative button on the other end for adjustable styles.

• For Casual Jackets:

  Cut two lengths of elastic cord, one for the waist and another for the hem. The waist length should be the jacket's waist measurement minus 10% for a gathered effect. The hem length is the same as the jacket's hem measurement. Secure the ends with fabric glue or by stitching them to a small piece of fabric inside the jacket.

• For Swimwear:

  Swimwear requires a resilient elastic cord. Cut a length that fits snugly around the waist or hips, then secure the ends with a zigzag stitch on a sewing machine. This allows the cord to stretch and move without breaking the thread.
