AI Technical Summary

Technical Problem

Existing unidirectional moisture-conducting fabrics suffer from poor water fastness, reverse osmosis, rough surfaces, and limited application range due to hydrophobic yarns lacking water-locking function, leading to reduced skin comfort and durability.

Method used

A preparation method involving weaving yarns with different filament numbers and applying a fluorine-free waterproof additive through a weft knitting process to create a lacoste weave structure, enhancing moisture conduction and evaporation efficiency while maintaining skin comfort.

Benefits of technology

The fabric achieves rapid moisture absorption and drainage with high anti-reverse-osmosis strength, maintaining unidirectional moisture conduction even after washing, and ensuring high surface comfort and skin affinity.

Abstract

The present application discloses an anti-reverse-osmosis unidirectional moisture-conducting fabric and a preparation method thereof, which achieve unidirectional moisture conduction by utilizing a filament thickness difference between bottom yarns and surface yarns of the fabric, and also achieve the most effective anti-reverse-osmosis unidirectional moisture conduction effect in combination with a dynamic printing water-locking characteristic of a fluorine-free waterproof additive. The anti-reverse-osmosis unidirectional moisture-conducting fabric has high speeds of moisture absorption and drainage, high anti-reverse-osmosis strength, high surface comfort of the fabric and good skin affinity, and ensures no decline or disappearance of a unidirectional moisture-conducting function due to washing.
