Embodiment 1

[0021] A method for measuring the fiber content of a modified acrylic fiber and acrylic fiber blended fabric, including the following steps:

[0022] (1) Take all the samples and disassemble them into yarn shapes, put them in a weighing bottle, dry, cool and weigh to obtain the dry mass of the sample m 0 ;

[0023] (2) Put the weighed sample into a Erlenmeyer flask, add 100mL solution for each gram of sample, put a glass stopper, shake the flask to fully wet the sample, then put the flask into a constant temperature shaking water bath at 85℃ In the pot, continue to vigorously shake for 1 hour, in which the dissolving liquid is made of the following components by weight: 85 parts by weight of cyclohexanone, 1 part of 3-cyclohexylaminopropanesulfonic acid, and 0.8 parts of cyclohexanone oxime;

[0024] (3) Pour the dissolved sample into a glass sand core crucible, drain the liquid by vacuum suction, clean the residue in the crucible with absolute ethanol 2 times, and then clean it with...

Embodiment 2

[0030] A method for measuring the fiber content of a modified acrylic fiber and acrylic fiber blended fabric, including the following steps:

[0031] (1) Take all the samples and disassemble them into yarn shapes, put them in a weighing bottle, dry, cool and weigh to obtain the dry mass of the sample m 0 ;

[0032] (2) Put the weighed sample into an Erlenmeyer flask, add 120mL of dissolving solution per gram of sample, plug the glass stopper, shake the flask to fully wet the sample, then place the flask in a 95℃ constant temperature shaking water bath In the pot, continue to vigorously shake for 1 hour, in which the dissolving liquid is made of the following components by weight: 90 parts of cyclohexanone, 3 parts of 3-cyclohexylaminopropanesulfonic acid, and 1.2 parts of cyclohexanone oxime;

[0033] (3) Pour the dissolved sample into a glass sand core crucible, vacuum and drain the liquid, clean the residue in the crucible with absolute ethanol 3 times, and then clean it with tap w...

Abstract

The invention discloses a method for measuring modified acrylic and acrylic blended fabric fiber contents. The method comprises the following steps of (1) taking all samples, then splitting the samples into a yarn shape, placing in a weighing bottle, drying and cooling, and then weighing to obtain dry mass m0 of the samples; (2) putting the weighed samples into a conical flask, adding a solution,plugging a glass stopper, shaking the flask to fully wet the samples, placing the flask in a constant temperature oscillating water bath kettle, and carrying out continuous violent oscillation; (3) pouring the dissolved samples into a glass sand core crucible, carrying out vacuum suction and liquid drainage, cleaning and then carrying out vacuum suction, finally, drying the crucible and residues,cooling, and weighing to obtain the mass m1 of the residues, and calculating and acquiring a mass percentage P of modified acrylic fibers, wherein the P satisfies the following formula: P=100%-m1*d*100% / m0. By using the method for measuring the modified acrylic and acrylic blended fabric fiber contents, the measuring method is rapid and convenient, cost is low and a measured result is real and accurate.

Description

Technical field [0001] The invention belongs to the technical field of textile chemical composition quantitative analysis in the textile industry, and specifically relates to a method for measuring the fiber content of a modified acrylic fiber and acrylic fiber blended fabric. Background technique [0002] Acrylic fiber is known as man-made wool. It has the advantages of softness, fluffy, bright color, light resistance, antibacterial, etc. However, with the improvement of living standards, conventional acrylic fibers can no longer meet people's needs, and modified acrylic fibers make up for the advantages of ordinary acrylic fibers. Some shortcomings, anti-pilling, anti-static and other functions, so acrylic fiber, modified acrylic fiber blended products are increasing; and due to the increasing awareness of animal protection today, all kinds of fake fur and other fabrics are more and more popular in the market . [0003] With the large-scale application of these products, quantit...
