What Is a Fold Over Elastic?
Fold Over Elastic is an elastic band widely used in clothing, sporting goods and home decoration. It is designed to have good elasticity and comfortable fit during use.
Definition:
Fold Over Elastic are usually made of elastic fibers and fabric materials. After a special folding process, the edges of the elastic bands are neat and have a certain thickness. Its structure generally includes elastic fibers (such as spandex, lycra, etc.) as the core, and the outer layer is wrapped or folded by fabric to make it elastic without directly exposing the elastic fibers.
Features:
-
Good elasticity: The elasticity of the Fold Over Elastic allows it to stretch and recover, providing a comfortable fit and flexible space for movement.
-
Soft and comfortable: The outer fabric wrapping makes the Fold Over Elastic very soft and skin-friendly, suitable for applications that directly contact the skin, such as underwear, sportswear, etc.
-
Strong durability: Due to the use of elastic fibers, the Fold Over Elastic has high durability and long-term use performance.
-
Beautiful: The folded design makes the edge of the elastic flat and beautiful, suitable for use as clothing decoration or practical belt.
-
Multiple applications: In addition to clothing, it can also be used for other products such as handbags, pajamas, sweatpants, etc.
-
Customizable: The Fold Over Elastic can be customized in color, width, pattern, etc. according to demand to meet the needs of different customers.
The Material of Fold Over Elastic
The material selection of the Fold over elastic directly affects its elasticity, durability, comfort and applicable scenarios. Common Fold over elastic materials include:
1. Nylon
Features: Nylon is a strong, lightweight synthetic fiber with good elasticity and wear resistance. Nylon elastic bands are highly elastic, can withstand large tensile forces, and have a smooth surface and good durability.
Impact on Fold over elastics:
-
Elasticity: Nylon material has good elasticity, can maintain a long-term stretched state, and is not easy to lose elasticity.
-
Durability: It has strong wear resistance, but may degrade under long-term exposure to ultraviolet rays or high temperature environments.
2. Polyester
Features: Polyester has strong tensile resistance and durability and can withstand high pressure. Although its elasticity is not as good as nylon, it has better anti-aging properties.
Impact on Fold over elastics:
-
Elasticity: It has moderate elasticity, not as strong as nylon, but can maintain a long-term stretching effect.
-
Durability: Polyester has good UV resistance, moisture resistance and heat resistance, suitable for use in a variety of environments, especially for outdoor or high humidity scenes.
3. Rubber
Features: Rubber elastic bands have very good elasticity, strong elastic recovery, and can quickly return to their original shape. Rubber elastic bands are usually used in situations where high elasticity is required.
Impact on Fold over elastics:
-
Elasticity: Excellent elasticity, able to withstand large tension and recover quickly, suitable for sports, clothing and other occasions that require strong elasticity.
-
Durability: Poor wear resistance, easily affected by heat, light and oxidation, may age and break over time.
4. Cotton
Features: Cotton elastic bands are softer and more comfortable, suitable for close-fitting wear. Cotton is not as elastic as synthetic fibers, but it is skin-friendly and suitable for sensitive skin.
Impact on Fold over elastics:
-
Elasticity: Poor elasticity, not as good as nylon and rubber, but more comfortable.
-
Durability: Poor durability, easy to wear and deform, not suitable for long-term tension.
5. Spandex or Lycra
Features: Spandex has extremely high elasticity and strong stretchability, and can be stretched to more than five times its original length. It is often blended with other fibers to enhance elasticity.
Impact on Fold over elastics:
-
Elasticity: Very strong, can quickly return to its original shape, suitable for use occasions that require strong elasticity and comfort.
-
Durability: Poor durability, after long-term use, it may lose some elasticity due to excessive stretching.
6. Polyurethane
Features: Polyurethane has strong elasticity, wear resistance, aging resistance, and can withstand long-term stretching without losing elasticity. Suitable as an elastic band material for high-intensity use.
Impact on Fold over elastics:
-
Elasticity: Has good elasticity and recovery.
-
Durability: More durable than rubber, with good UV resistance and water resistance, suitable for long-term use.
Application of Fold Over Elastic
Here are some common applications for Fold over elastic:
1. Garment manufacturing
-
Waistbands and skirt waistbands: Fold over elastic are often used in the waist of pants, skirts, sweatpants and other clothing to provide comfortable stretch and fit, and can better adapt to different body shapes.
-
Underwear and swimsuits: Used in tight clothing such as underwear and swimsuits to enhance the comfort of wearing and avoid discomfort when directly contacting the skin.
-
Children's clothing: Since Fold over Elastic are softer and more comfortable, they are suitable for children's clothing to reduce irritation to children's skin.
2. Sportswear

The Production Process of Fold Over Elastic
1. Selecting materials
Elastic fabric: Nylon, polyester, cotton or other synthetic fibers are generally used to make elastic bands. Choosing the right material depends on the application, such as clothing, footwear, sportswear, etc.
Elastic thread or rubber strip: The elasticity of the elastic band is usually provided by the inner elastic thread (such as rubber thread).
2. Weaving elastic band
Weaving: The fiber threads are woven according to the designed width and pattern to form the basic fabric of the elastic band.
Adding elasticity: During the weaving process, elastic materials (such as rubber threads) are inserted in the middle of the fabric or used as an outer layer to ensure that the elastic band has the function of stretching and retracting.
3. Fold over elastic
Heat setting or manual folding: After weaving, the elastic band is usually fed into a folding machine for heat setting and folding to ensure that the elastic band maintains a stable width and shape.
Folding according to design requirements: Some elastic bands are completed in a specific folding style (such as single fold, double fold or multi-fold), and the specific folding method depends on the design requirements and application.
4. Fixing and pressing
Heat sealing or pressing: The Fold Over Elastic will be fixed by heat sealing or mechanical pressing to prevent the elastic band from spreading or losing its folded shape.
Reinforced edges: Some elastic bands will be reinforced at the edges to prevent them from unraveling or fraying.
5. Testing and inspection
Elasticity test: Check the elasticity and tensile properties of the elastic band to ensure that it can stretch normally and rebound quickly.
Dimension and appearance inspection: Ensure that the width, folded shape and color of the elastic band meet the design requirements and have no defects.
6. Packaging and delivery
Coiling or cutting: According to customer requirements, the elastic band is rolled into rolls or cut into sections according to the required length.
Packaging: Packaging into rolls, bags or boxes for easy transportation and sales.
