Embodiment 1

[0041] Single mercerizing yarn mercerizing detection: first establish the relationship equation between barium value and moisture regain, and then use this relationship equation to test the barium value of single mercerized fabric.

[0042] Step 1: Firstly, use the traditional barium value method to determine the barium value of 5 groups of monofilament yarn samples as a basis. The specific steps are as follows:

[0043] (1) Sample pretreatment: Take 5g each of the monomererized yarn and absorbent cotton, put these 5 groups of samples and absorbent cotton into the Soxhlet extractor, extract with petroleum ether for 1 hour, and circulate at least 6 times per hour, then Wash it with 95% ethanol, then wash with distilled water, then put the samples in soap solution and boil for 1 hour, rinse with distilled water repeatedly until they are completely washed, after drying, weigh 4g each of the samples and cut them into length 0.5cm.

[0044] (2) Making the immersion solution: place the pr...

Embodiment 2

[0056] Double mercerized fabric mercerizing detection: first establish the relationship equation between barium value and moisture regain, and then use this relationship equation to test the barium value of double mercerized fabric.

[0057] Step 1: Firstly, use the traditional barium value method to determine the barium value of 5 sets of double mercerized fabric samples as a basis. The specific steps are as follows:

[0058] (1) Sample pretreatment: Take 5 sets of double mercerized fabric samples and 5g of absorbent cotton, put the samples into a Soxhlet extractor, and extract with petroleum ether for 1 hour, circulate at least 6 times per hour, and then use 95% Wash the samples with the ethanol solution again, then rinse with distilled water, and then put the samples in the soap solution and boil for 1 hour, rinse them with distilled water repeatedly until they are completely washed, after drying, weigh 4g of the samples and cut them into 0.5cm length.

Abstract

The invention is suitable for the field of textile production and detection, and provides a measurement method for the mercerization degree of mercerized cotton. The measurement method comprises the following steps: establishing a relation equation between the moisture regain and the mercerization degree of the mercerized cotton; measuring the moisture regain of the mercerized cotton to be measured; substituting the moisture regain of the mercerized cotton to be measured into the relation equation, and calculating to obtain the mercerization degree of the mercerized cotton to be measured. According to the measurement method for the mercerization degree of the mercerized cotton, a new effective method is provided for quantitatively analyzing the mercerization degree of the mercerized cotton. The measurement method has the advantages of simple detection technology, convenience in equipment operation, high accuracy, good reproducibility, high efficiency and easiness in popularization and promotion.

Description

Technical field [0001] The invention belongs to the field of textile production and detection, and particularly relates to a method for measuring the mercerization of mercerized cotton. Background technique [0002] At present, testing institutions and related companies use the barium value of mercerized cotton to determine the mercerizing degree of mercerized cotton products. According to AATCC Test Method 89-2012 "Mercerizationin Cotton", the barium value is defined as the sample absorbs barium hydroxide after mercerizing. 100 times the ratio of the amount of barium hydroxide absorbed by the unmercerized standard cotton sample. The barium value directly reflects the quality of mercerizing technology, which affects the commercial settlement of fabric products and the wearing performance of clothing, such as dimensional stability, wrinkle resistance, drape, water permeability, etc. Mercerized cotton products are tested in China. The barium value method is used outside. Accordin...
