Testing method for drying performance of wool fabric

Abstract

The invention relates to a testing method for drying performance of a wool fabric, which is mainly used for testing naturally drying performance of a soaked fabric. The principle of the testing method is that performing balance weighing on a dry-cleaned wool fabric, soaking the dry-cleaned wool fabric into water with certain penetrating agents for absorbing water in a penetrating mode for certaintime, then taking the wool fabric out, hanging the wool fabric for drying in a dripping mode under the conditions of standard temperature and humidity, weighing the test sample at set intervals, and recording the time required by recovering the weight of the test sample before soaking as the natural drying time of the fabric according to comparison on weight changes of the wool fabric before soaking and after soaking. The testing method for the drying performance of the wool fabric utilizes an instrument for testing dry cleaning and a reagent for dry cleaning, thereby avoiding different additive and instability of operation. The reagent has strong penetrating quality so that water can be completely absorbed by the fabric, a water absorbability test can be finished in a short time, test results are quick and timely, a test method is simple and practical, no special detection equipment is required to be configured, and test cost is low.

Description

technical field [0001] The invention relates to a method for testing the drying performance of wool fabrics, which is mainly used for testing the natural drying performance of fabrics after they are soaked. 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. Through fabric structure design, the use of new modified fibers and finishing Auxiliary processing and other methods to improve or improve the performance of non-hydrophilic fabrics on moisture absorption, transfer, and discharge, so that they have 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,...

Problems solved by technology

[0003] At present, there are many manufacturers of functional woolen fabrics, but none of them have effectively tested and analyzed the drying performance of woolen fabrics, because woolen fabrics are water-repellent, and moisture cannot enter the fabric, and the amount of water absorbed will directly affect the accuracy of the test results. Therefore, the drying performance of wool fabrics in the past was not tested, and the moisture removal performance of wool fabrics could not be guaranteed.
