Product Details
Factory Custom Spandex Crochet-Knit Elastic Band
This crochet-knit elastic band is engineered for close-fitting apparel where dependable stretch recovery and a soft hand feel are essential. It is produced with Korean Hyosung 840D spandex combined with polyester filament, giving the band a resilient elastic core wrapped in a smooth, tightly constructed textile surface. The 20-needle crochet-knit construction creates the fine, uniform ribbed appearance visible in the product photographs, with a clean edge that resists rolling during sewing and wear.

The band is offered in widths from 3 mm to 30 mm and is available for custom production, allowing garment makers to specify the dimensions that match their pattern requirements. It is a practical choice for underwear, sleepwear and children’s wear, where elasticity, comfort against the skin and consistent quality across bulk runs are the main selection criteria.

Applications
Underwear and Intimate Apparel
The combination of elastic recovery and a smooth knitted surface makes this band suitable for waistbands, leg openings, straps and edge finishing on underwear and other close-fitting garments. The band flexes with body movement and returns to shape, which helps maintain fit after repeated wear and laundering.
Sleepwear and Loungewear
For pyjamas, nightwear and loungewear, comfort is the priority. The crochet-knit structure keeps the band soft and pliable, so it can be sewn directly against the skin without a stiff or abrasive feel. Narrow widths work well for delicate trims, while wider widths suit waistbands.
Children’s Wear
Children’s clothing requires elastics that stretch easily and hold their shape through frequent washing. This band’s spandex content supports the flexibility needed for garments that must be easy to put on and take off, and its skin-friendly composition is appropriate for items worn next to the body.

Core Features
- Reliable elasticity: Korean Hyosung 840D spandex delivers strong stretch and recovery, helping garments keep their intended fit over time.
- Durable knit structure: The 20-needle crochet-knit construction produces a dense, even surface that resists distortion during cutting, sewing and everyday wear.
- Skin-friendly material: A soft polyester and spandex blend, developed with comfort in mind for garments worn close to the body.
- Consistent appearance: The uniform ribbed face provides a clean, tidy finish that can be left exposed or concealed inside a seam.
- Flexible sizing: Widths from 3 mm to 30 mm cover narrow trim applications through to wider waistband uses.
