Methods of Fabric Treatment

Summary

Fiber or fabric treatments for achieving valued added properties are valuable in textiles, home furnishing, and composite material industries. Various processes have been developed to achieve wrinkle-free/durable-press (DP) properties or antibacterial properties. However, they all suffer drawbacks such as losses of tensile strength, abrasion resistance, and tear strength.

This invention provides a method for controlling the physical and chemical properties of fibers or fabrics via hierarchical crosslinking architecture (NHCA) at nanometer or micrometer scale. The architecture, proved by scanning microscopy study, has improved the mechanical properties of a fabric evidenced by measurement of tensile strength, tear strength and recovery angle of a cotton fabric.

This architecture, which consist a thin film with nanometer or micrometer domains with multiple interactions, is generated using crosslinking reagents and nanoparticles (with or without multifunctionalities). In addition, such architecture not only provides tailor-made chemical and physical properties but also improves the efficiency of the treatment of the fabrics. This new invention can be applied to various fibers, fabrics, or textiles for enhancing their properties.

Technology Benefits

1. Distinct mechanical and chemical properties are generated in controlled fashion, thus offer desired enhancements in tensile strength and tear strength
2. The time of immersion fabrics in the bath of nanoparticles is reduced, thus leads to higher efficiency of the process of the treatment
3. Recovery angles correlate to the pick-up of nanoparticles, which can be controlled easily by the concentration of nanoparticles
4. It gives a well-defined structure, thus offering the potential for property design and control

Technology Application

- Treatment of fabrics, yarns and fibers for enhanced properties
