Testing method for moisture absorption performance of wool fabric

Abstract

The invention relates to a testing method for a moisture absorption performance of a wool fabric, which comprises the following steps: putting a sample into a washing instrument container; adding tetrachloroethylene to serve as a dry cleaning agent; sealing and then putting into a dry cleaning instrument; performing drying cleaning, and then, taking out the sample; then, repeating washing for twotimes; then, laying the dry cleaned fabric flat on a desktop; dropping a certain amount of water on the fabric, thus, a water drop permeates into the fabric from a cloth cover to form a watermark spot on the cloth cover; and measuring the diameter of the permeating spot in the scheduled time to obtain the moisture absorption performance parameter of the fabric. According to the characteristic of dry cleaning resistance of the wool fabric, the wool fabric sample is put into the washing instrument container; the tetrachloroethylene is added to serve as the dry cleaning agent; the wool fabric sample is put into the dry cleaning instrument for dry cleaning after being sealed; then, the washing is repeated for two times; and the consistency of dry cleaning of each time is ensured, thereby, theinfluence of the dry cleaning on moisture absorption performance testing on the wool fabric is avoided. Moreover, the testing method is simple and practical, is rapid and timely in testing result, iscapable of completing testing in short time and is low in testing cost.

Description

technical field [0001] The invention relates to a method for testing the water absorption performance of wool fabrics. Background technique [0002] In recent years, wool fabrics with moisture-absorbing and sweat-wicking functions have been developed. Wool fabrics are light and thin, vapor-permeable and have certain moisture-wicking and sweat-wicking functions to meet the needs of consumers. To improve or improve the performance of non-hydrophilic fabrics on water absorption, transfer, discharge, etc., so that it has both water absorption and moisture conductivity. The process of wool fabric transferring water can be divided into four stages: wool fabric contacting water, absorbing water--water transportation--storage-water evaporation and dehumidification. Among them, the water absorption stage is extremely important. The wool fabric needs to absorb water effectively to make the sweat of the human body be discharged in time, instead of adhering to the body. In order to ens...

Problems solved by technology

[0003] At present, there are many manufacturers of functional wool fabrics, but none of them have effectively tested and analyzed the water absorption performance of wool fabrics, because wool fabrics need to be dry-cleaned before the water absorption performance test, and the functional finishing of wool fabrics requires dry-cleaning resistance. , needs to be dry-cleaned many times, but the water-absorbing performance of the woolen fabrics after repeated dry-cleaning is inconsistent, which makes it impossible to accurately measure whether its water-absorbing performance meets the standard. Therefore, general functional wool fabric manufacturers do not test their water-absorbing performance
