Polyester DTY Stretch Sewing Thread for Knitwear and Overlocking
Soft textured polyester thread with controlled stretch and seam coverage for activewear and elastic fabrics.
Product Overview
Polyester DTY stretch sewing thread is made from draw-textured polyester yarn that combines softness, bulk and controlled elasticity. The textured filament structure provides good seam coverage and a comfortable hand in overlock, cover-seam and selected sewing operations. It follows moderate fabric stretch more effectively than ordinary rigid thread and recovers after extension, helping reduce popped stitches in knitwear and active garments. Polyester also brings low shrinkage, color retention and moisture resistance. The thread can be developed in different deniers, colors, finishes and cone formats for underwear, sportswear, swimwear and elastic home textiles.

FAQ
How is DTY thread different from ordinary polyester sewing thread?
DTY has a textured, bulkier filament structure with more softness and controlled stretch, making it useful for overlocking and elastic fabrics.
Is it suitable for very high-stretch spandex?
It suits many moderate-stretch fabrics. For extreme elongation, compare it with nylon high-stretch thread and test the final seam.
Which machines use this thread?
It is commonly developed for overlock and cover-seam loopers, and may be used in other compatible operations after machine testing.
Does it provide soft seams?
The textured bulk improves coverage and reduces a hard thread feel, which is valuable in next-to-skin garments.
Can denier and cone size be customized?
Yes. Denier, ply, winding, label and carton can be matched to factory requirements.
Will it shrink after washing?
Heat-set polyester DTY generally has low shrinkage, but actual results depend on yarn specification and garment process.
Can you match activewear colors?
Yes. Provide an approved fabric swatch or color reference for sampling.
Do I need to adjust machine tension?
Often yes. Textured thread may require different looper tension and needle pairing than regular spun thread.
How can I request a quotation?
Send denier or sample, color, cone size, quantity, application, packing and delivery destination.
