ShowarmX® Keeping Warm Hollow Polyester Yarn

ShowarmX® hollow polyester yarn has a filament hollow degree of ≥22%. Its internal air cavity replaces part of the polymer found in a solid polyester filament of the same outer dimensions, making it a promising option for lightweight thermal textiles. The weight and warmth of a finished fabric depend on yarn count and fabric construction. Applications include winter apparel, bedding and insulation materials.

How it Works

ShowarmX® hollow polyester yarn has a filament hollow degree of ≥22%. Its internal cavity replaces part of the polymer in a solid polyester filament of the same outer dimensions, offering a potential route to lighter textile constructions. The weight and thermal performance of a finished fabric depend on yarn count, fabric structure and finishing, and should be assessed in the intended application.

Lightweight Design
A hollow filament uses less polymer than a solid polyester filament of the same outer dimensions. This structure offers a route to lighter fabric designs, while the finished weight depends on yarn count, fabric construction and finishing.

Thermal Insulation
With a filament hollow degree of ≥22%, ShowarmX® has an internal cavity that can help retain air. This structure supports the development of insulating textiles; the warmth of a finished fabric depends on its construction, thickness and intended layer system.
