Comparative analysis: TPU elastic tape vs. traditional elastic tape

In the textile and garment industry, elastic tapes are common auxiliary materials. With the advancement of technology, the types and properties of materials are constantly being updated. There are various types of elastic tapes in the market. Here we talk about the difference between TPU elastic tape and traditional elastics.

Material composition

TPU elastic tape are primarily made of TPU material, thermoplastic polyurethane elastomer. TPU is a polymer that combines the properties of rubber and plastic, offering excellent elasticity, abrasion resistance, and weather resistance. TPU elastic tape are usually produced through a high-temperature extrusion process and are characterized by being environmentally friendly, non-toxic, and odorless.

Traditional elastic tapes are usually made from polyester fibers, rubber threads, or spandex threads. Polyester fibers provide good strength and durability, while rubber and spandex threads offer elasticity. These materials are produced through weaving, knitting, or braiding processes, with a more complex composition that may include additional chemicals to enhance performance.

Performance characteristics

1. TPU elastic tape

(1) Excellent elasticity: TPU elastic tape has outstanding elasticity and rebound, maintaining their shape even after repeated stretching.

(2) High abrasion resistance: Due to the properties of TPU material, TPU elastic tape is resistant to wear and tear, providing a long service life.

(3) Good weather resistance: TPU elastic tape maintains stable performance under various environmental conditions and are not prone to aging.

(4) Environmentally friendly and non-toxic: TPU materials are non-toxic and odorless, meeting modern health and environmental standards.

(5) Transparent and lightweight: TPU elastic tape has high transparency, achieving an invisible effect that does not affect the appearance of the garment.

2. Traditional elastic tape

(1) Moderate elasticity: The elasticity and rebound of traditional elastic tape depend mainly on rubber or spandex threads and are relatively inferior.

(2) Moderate abrasion resistance: Traditional elastic tapes are prone to wear and tear and breakage under frequent use.

(3) Moderate weather resistance: Traditional elastic tapes are more susceptible to environmental influences, especially prolonged exposure to sunlight, which accelerates aging.

(4) Complex composition: Traditional elastic tape may contain various chemical additives, which can potentially irritate the skin.

(5) Opaque: Traditional elastic tapes are usually opaque and require dyeing to match the garment color.

Appearance and texture

TPU elastic tape is transparent and lightweight, providing an invisible effect that does not affect the overall aesthetics of the garment. It is soft and skin-friendly, causing no discomfort to the skin.

Traditional elastic tape are typically opaque products made of polyester, rubber, or spandex, appearing rougher. Their texture is relatively stiff, and prolonged skin contact may cause discomfort.

Application fields

1. TPU Elastic Tape:

(1) Knitwear: Suitable for cuffs, waist tape, necklines, and shoulder seams, providing excellent elasticity and support.

(2) Underwear and swimwear: The transparency, lightness, and superior elasticity of TPU elastic tape make them ideal for underwear and swimwear.

(3) Sportswear: The abrasion resistance and weather resistance make them suitable for sportswear and active-wear, ensuring long-lasting comfort and performance.

(4). Medical accessories: Due to their non-toxic, odorless nature and excellent elasticity, TPU elastic tape are also widely used in the medical field, such as elastic bandages and surgical gowns.

2. Traditional elastic tape:

(1) Everyday clothing: Widely used in waist tape, cuffs, and hems that require elasticity.

(2) Household items: Traditional elastic tapes are also used in items like bed sheets and sofa covers.

(3) Industrial uses: Due to their strength and durability, traditional elastic tape are employed in various industrial products.

Price differences

The production cost of TPU elastic tape is higher, mainly because TPU material is more expensive and the production process is complex. Therefore, the market price of TPU elastic tape is generally higher than that of traditional elastic tape.

Traditional elastic tapes have lower material costs, mature production processes, and relatively low market prices. They are suitable for cost-sensitive applications.

Overall, TPU elastic tape offer significant advantages in terms of elasticity, abrasion resistance, weather resistance, and environmental friendliness, making them suitable for high-end garments and specialized applications. However, traditional elastic tape remains essential in many fields due to their lower costs and wide applicability. The choice between TPU and traditional elastic tape depends on specific application scenarios, performance requirements, and budget. For high-quality and specialized performance needs, TPU elastic tape are undoubtedly the better choice, while traditional elastic tape offers more economic solutions for everyday use and cost-sensitive scenarios.
