AI Technical Summary

⚠Technical Problem

Existing technologies in the finishing process of Tencel and nylon composite fabrics suffer from problems such as interfacial energy level mismatch leading to uneven distribution and poor durability of functional components on the fiber surface, and traditional methods may damage the fibers or fail to meet green and environmental protection requirements.

⚗Method used

By employing a heterogeneous swelling domain mediated by a eutectic solvent and combining it with bio-enzymatic finishing, synchronous and uniform covalent anchoring of Tencel and nylon fiber surfaces is achieved through low-temperature cooling and covalent bridging. The hydrogen bond donor network of the eutectic solvent and the covalent bond formation catalyzed by laccase are utilized to avoid high-temperature baking and the use of chemical crosslinking agents.

🎯Benefits of technology

It achieves uniform distribution and high-durability covalent anchoring of functional components in Tencel and nylon composite fabrics under mild conditions, improves the wash fastness and mechanical properties of the fabric, and meets green ecological standards.

Abstract

This invention relates to the field of textile finishing technology, and discloses a high-performance Tencel and nylon composite skin-friendly fabric and its green preparation process, including: impregnating the Tencel and nylon composite fabric with a eutectic solvent composed of choline chloride and urea to induce internal swelling of the fibers and expose active sites; constructing a finishing system using gallic acid-modified collagen peptides and laccase, and immobilizing peptide molecular chains on the fiber surface through an enzymatic grafting reaction; driving solvent dissolution and causing a physical phase change in the surface layer by utilizing a low-temperature cooling environment. The cold trap phase change quenching mechanism of this invention triggers the transformation of peptide macromolecules at the interface from a flexible state to a rigid gel state, so that the physical phase change solidification shrinkage and the chemical covalent cross-linking form a deeply nested interlocking structure, mechanically locking the skin-friendly peptide network in the pores of the composite yarn and the fiber surface. At the same time, the polymer network forms an elastic topological constraint between Tencel microfibers, realizing permanent in-situ anti-fibrillation improvement of the fabric.
