Textile finishing for silky-cool hand feel

HeiQ Serica™ uses a bio-based, silicone-free system based on silk proteins and vegetable oils. This approach delivers a more natural, premium hand feel compared with conventional textile softeners.

The biopolymer matrix acts as a carrier that encapsulates silk proteins and vegetable oils. It helps protect these components during textile processing and supports their gradual release onto the fiber surface over time, contributing to a smooth, silky hand feel while maintaining fabric performance.

A biopolymer matrix encapsulates silk protein and vegetable oils and releases them gradually onto the fabric surface. This process helps reduce fiber-to-fiber friction and creates a smooth textile surface. 

Yes. The silky hand feel delivered by HeiQ Serica™ is designed to remain effective through repeated home laundering.

HeiQ Serica™ is evaluated using advanced textile testing methods for softness, smoothness, and tactile performance, led by the EMTEC TSA (Tactile Sensation Analyzer), which objectively measures properties such as softness, roughness, and surface texture.

Testing confirms measurable improvements, including enhanced softness (up to 27%) and reduced roughness (up to 36%), ensuring a premium hand feel.

Additional validation includes anti-static testing and skin compatibility (human patch testing), supporting both performance and safety.

HeiQ’s biotechnology platform uses nature derived polymers, prebiotic, probiotic, and postbiotic ingredients and translates natural and biological processes into scalable product technologies across textiles, home care, personal care, water, and animal care. By combining biology, chemistry, and materials science, HeiQ applies nature‑inspired mechanisms, including microbiome‑based systems, bio‑based encapsulation, and functional finishes, to deliver reliable performance across multiple industries.

Yes. Different textile finishes can be combined on the same fabric to deliver multiple effects at once. The key is formulation and process control. Finishes must be compatible and engineered to work side‑by‑side during application and remain stable during use and washing. Well‑designed combinations extend fabric functionality without changing how the textile feels or behaves in daily wear. For example, a garment can manage moisture while also reducing odour build‑up.
