Embodiment Construction

[0037] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment;

[0038] This embodiment provides a kind of quantitative analysis method of acrylic fiber, is used for the quantitative analysis of acrylic fiber and polyamide fiber, acrylic fiber and polyester fiber, acrylic fiber and viscose, acrylic fiber and tencel fiber blending quantitative analysis, comprises the following steps:

[0039] a) Put the acrylic fiber blended sample into a constant temperature oven to dry, cool, and then weigh. In one embodiment, put the acrylic fiber blended sample into a weighing bottle and dry it in a constant temperature oven at (105±3)°C. After two hours, take out the weighing bottle and put it in a desiccator. Cool for 30 minutes; then weigh the acrylic fiber blended sample.

[0040] b) Put the acrylic fiber blended sample into the Erlenmeyer flask, add 100mL of 6.5mol / L zinc chloride solution per gram of the sample, plug t...

Abstract

The invention discloses a quantitative analysis method for acrylic fibers. The method is not prone to damage experimenters during operation and has the characteristics of energy conservation, low toxicity, low consumption and environmental protection. The method comprises: a) putting a mixed acrylic fiber sample in a constant temperature oven for drying and performing cooling and weighing; b) putting the obtained mixed acrylic fiber sample in a conical flask, adding 100 ml of a zinc chloride solution in every one gram of the sample, wherein the concentration of the solution is 6.5-12 mol/L, plugging the conical flask with a glass stopper, shaking the flask to fully wet the sample, and putting the conical flask in a constant temperature water bath oscillator for oscillation; c) filtering the left sample into a glass crucible provided with a sand core, vacuum-drawing a discharge liquid, washing the left sample with water, vacuum-drawing a discharge liquid, totally transferring the left sample in the flask to the glass crucible by washing the flask with water for several times, performing vacuum-drawing, drying the crucible and the left sample, and performing cooling and weighing; d) calculating the mass of components in the mixed acrylic fiber sample; and e) obtaining the mass percentage of each component in the mixed acrylic fiber sample.

Description

technical field [0001] The invention belongs to the technical field of component content testing of acrylic fiber blended products, and in particular relates to a quantitative analysis method for acrylic fiber. Background technique [0002] With the continuous improvement of material living conditions, the growth of population and the continuous improvement of people's material consumption level, my country's demand for textiles has been continuously strengthened, which has promoted the rapid development of my country's textile raw materials. Acrylic fiber is known as artificial wool. It has the advantages of softness, fluffiness, easy dyeing, bright color, light resistance, antibacterial, and no fear of insects. According to the requirements of different uses, it can be purely spun or blended with natural fibers, artificial fibers, and other synthetic fibers. Its textiles are widely used in clothing, decoration, industry and other fields, and are one of the important raw mat...
