Problems solved by technology

This method is generally advisable in daily life practice, but the accuracy rate is low, and many fabrics in daily life have no label display, and only rely on human senses to guess, the accuracy is very low
[0003] The second is destructive identification. The sample cloth is taken, and the cotton content is judged by parameters such as ash color, ash shape, and combustion gas after ignition. Exploitation of destruction
[0004] With the development of the economy and the improvement of people's material level, more and more people choose pure cotton clothes when buying clothes. However, the level of science and technology is also constantly improving. Real cotton, and this kind of fabric has poor hygroscopicity, which is easy to cause adverse reactions such as skin allergies. At the same time, the only method to identify the cotton content of clothing has limitations, unscientific, low accuracy and other shortcomings

Embodiment 1

[0029] A method for detecting the cotton content of cloth is characterized in that it comprises the following steps:

[0030] Step 1) Preparation of standard samples: take light-colored cloths with cotton content of 100%, 95%, 75%, and 0% respectively to obtain standard samples;

[0031] Step 2) Titration of the cloth standard sample: determine the titration point on the cloth standard sample in the step 1), draw a certain titration solution with a capillary pipette, vertically stand the capillary above the titration point, and make the lower part of the capillary contact with the titration point surface , and start timing, record the height of the capillary liquid column, and calculate the titration per unit time by this method, which is the titration rate;

[0032] Step 3) detection of the cloth to be tested: take the cloth to be tested, and titrate the cloth to be tested according to the method of step 2), so as to obtain the average titration rate of the cloth to be tested...

Embodiment 2

[0043] A method for identifying the cotton content of cloth, the method comprising the following steps:

[0044] Step 1) standard sample making: take the cloth whose cotton content is known, clean it up, and obtain the cloth standard sample;

[0045] Step 2) titration solution selection: aqueous solution;

[0046] Step 3) titration of the cloth standard sample: determine the titration point on the cloth standard sample of the described step 1), draw the titration solution of the described step 2) with a capillary tube with a length of 100mm, vertically stand the capillary above the titration point, make The lower part of the capillary contacts the surface of the titration point, starts titration and timing, records the titration amount per unit time, and calculates the titration rate of the standard sample cloth;

[0047] Step 4) Detection of the cloth to be tested: take the cloth to be tested, according to the method of the step 1) to the step 3) of the cloth to be tested, i...

Embodiment 3

[0053] Titration rate of cloth with different cotton content,

[0054] The method of Example 1 is used to titrate cloths with different cotton contents, and the titration rates of different cloths are shown in Table 1. Since the main component of cotton is cellulose, which contains hydrophilic pores, the more hydrophilic pores, the better the water absorption. Compare the average titration rates of several fabrics with different cotton contents in Table 1. The average titration velocity of 100% cotton is 0.2435cm / s, the average titration velocity of 95% cotton is 0.207cm / s, the average titration velocity of 85% cotton is 0.175cm / s, and the average titration velocity of 75% cotton is 0.159cm / s s, which shows that the titration rate of the four fabrics is proportional to the cotton content.

Abstract

The invention discloses a method for detecting cotton content of fabric. The method comprises steps of selecting standard samples; selecting a titration solution; identifying the cotton content of thefabric according to standard sample titration rates obtained by titration on the standard samples of clothing. The method adopts nondestructive testing, damage to the clothing and generation of polluting gas are avoided in the identifying process, while samples are damaged and the environment is polluted in the common burning method. High-cost instruments and tools are not needed in the method, and the detection method is simple and has important significance in identification of the cotton content of the fabric.

Description

technical field [0001] The invention relates to the field of cloth identification and screening, in particular to a method for detecting the cotton content of cloth. Background technique [0002] At present, the methods of identifying the cotton content of clothing are roughly divided into the following categories: one is non-destructive identification, specifically including checking the data provided by the clothing label, observing the smoothness and softness of the clothing or touching it to judge its cotton content . This method is generally advisable in daily life practice, but the accuracy rate is low, and many fabrics in daily life have no label display, and the accuracy is very low only by human senses. [0003] The second is destructive identification. The sample cloth is taken, and the cotton content is judged by parameters such as ash color, ash shape, and combustion gas after ignition. use of destruction. [0004] With the development of the economy and the i...
