Purpose

This study aims to examine the effect of laundering on the softness and smoothness of terry-cloth towels by different washing machine type, washing temperature, drying method and the use of fabric softener, using a newly developed sound spectrum analysis known as Textile Softness Analyzer.

Design/methodology/approach

The experiment was designed to analyze the most significant laundering parameter in the reduction of softness and smoothness of terry cloth during one laundering cycle up to ten cycles by testing samples using TSA machine.

Findings

A front-loading washer had a significant effect on reducing softness and smoothness in comparison to a top-loading machine; line-drying resulted in a higher decrease in softness and smoothness than tumble-drying. Washing temperature showed no significant effect, and the use of softener during washing was able to reduce the negative effect of line-drying on the softness and smoothness of terry cloth.

Originality/value

This paper provided information on the laundering parameters that can maintain the softness and smoothness of terry-cloth towels, and this was examined with sound spectrum analysis to measure softness and smoothness of textiles.

利用声谱分析反复洗涤对毛巾布柔软光滑度的影响

目的

本研究旨在使用一种新开发的声谱分析仪纺织品柔软度分析仪，研究不同洗衣机类型、洗涤温度、干燥方法和织物柔软剂的使用对毛巾毛巾柔软度和光滑度的影响。

设计/方法/方法

该实验旨在通过使用 TSA 机器测试样品来分析在一个洗涤循环到十个循环期间降低毛巾布柔软度和光滑度的最重要的洗涤参数。

发现

与上装式洗衣机相比，前装式洗衣机在降低柔软度和光滑度方面具有显着效果；与滚筒干燥相比，线干燥导致柔软度和光滑度下降更多。洗涤温度没有显着影响，洗涤过程中使用柔软剂可以减少线干对毛巾布柔软度和光滑度的负面影响。

原创性/价值

本文提供了有关可以保持毛巾布柔软度和光滑度的洗涤参数的信息，并通过声谱分析来测量纺织品的柔软度和光滑度。
