Non-slip Elastic Band

Definition and Overview

Non-slip elastic band is a stretch tape used to prevent clothing from shifting on the skin or over layered garments while being worn. Many types have a non-slip finish such as lines, dots, or patterns applied to the surface of the tape body, and they are used by sewing them in place where needed.

Compared with elastic webbing used to fit the waist or hems, non-slip elastic band is intended not only to provide holding power but also to suppress slipping through friction. However, since it is not merely a material for increasing tightness, it must balance holding performance with comfort.

Materials and Structure

Elasticity is generally achieved by a structure in which elastic yarn such as polyurethane is covered with yarn such as polyester or nylon. For the non-slip part placed on the skin side, silicone resin and similar materials are used.

The tape body may be made as woven elastic, knitted elastic, or braided elastic. Woven elastic tends to hold its shape relatively well, while knitted elastic tends to be soft and easy to stretch. Braided elastic is easier to give thickness and roundness to, and is used according to the application.

• Woven elastic: used for areas where a flat, stable texture is desired.
• Knitted elastic: suitable for areas that require a soft fit.
• Braided elastic: a structure that can more easily handle cord-like and raised shapes.

How to Read Width and Stretch

Width is selected according to the dimensions of the part to be sewn, the required contact area, and the sewing method. The wider the band, the larger the contact area, but thickness, firmness, and feel against the skin also change, so it is important not to judge holding power by width alone.

Stretch may be expressed as stretch ratio. This indicates how far it can be stretched relative to a standard length. In actual sewing, the cutting length of the tape relative to the finished garment size and the amount of pull applied during sewing are specified clearly in the specification sheet.

Main Applications

It is used in places where shifting during wear is likely to be a problem, such as the inside of pant and skirt waistbands, shirt hems, cuffs, sportswear, and innerwear. In applications that directly touch the skin, the shape of the non-slip surface and the firmness of the tape edge also affect comfort.

It may also be used around the shoulders of garments or on hanger loops for the purpose of preventing items from falling when hung on a hanger. In such cases, selection is based not on friction against the skin, but on friction with the target object and the sewing position.

Selection and Handling Precautions

When selecting, confirm the width, thickness, stretch strength, recovery, placement of the non-slip part, and compatibility with the textile to be sewn. Before mass production, make a prototype using the actual textile and sewing conditions, and check the anti-slip effect, tightness, seam puckering, and feel against the skin.

Elastic yarn may lose recovery after repeated excessive stretching, heat, ultraviolet exposure, or age-related deterioration. The performance and appearance of the non-slip part may also change through washing and friction, so testing and confirmation of labeling in line with the product's washing conditions are necessary.

• If it is pulled more than necessary during sewing, it can cause puckering after finishing and excessive tightness.
• During pressing or drying processes, direct high heat and high pressure on the non-slip part should be avoided.
• For light-colored or thin textiles, check in advance whether the non-slip part shows through or causes color transfer.

Frequently Asked Questions

What is the difference between non-slip elastic band and elastic webbing?

Elastic webbing is an elastic tape mainly used to fit clothing through stretch. Non-slip elastic band, in addition to this, suppresses shifting through friction from the surface non-slip finish. If you only need to tighten the waist, use elastic webbing; if you also want to prevent shifting, consider non-slip elastic band.

Can non-slip elastic band be used in direct contact with the skin?

Some specifications can be used on the skin side, but comfort differs depending on the non-slip material, the shape of the raised parts, the width, and the amount of tightness. For products that touch the skin directly, in addition to checking for irritation and pressure through try-on, it is important to confirm the condition after the expected washing cycle.

Does washing reduce the effect of the non-slip surface?

The appearance and friction performance of the non-slip part may change depending on washing, friction, heat, and the type of detergent. Check the handling conditions of the material to be used, and confirm through washing tests combined with the garment fabric that the anti-slip effect remains after repeated use and that there is no peeling.
