Embodiment 1

[0026] The preparation of the standard sample of embodiment 1 polyester and cotton fiber

[0027] There are 19 content ratios of polyester and cotton fiber, which are 5 / 95, 10 / 90, 15 / 85, 20 / 80, 25 / 75, 30 / 70, 35 / 65, 40 / 60, 45 / 55, 50 / 50, 55 / 45, 60 / 40, 65 / 35, 70 / 30, 75 / 25, 80 / 20, 85 / 15, 90 / 10, 95 / 5, prepare two standard samples for each ratio.

[0028] 1) Short fiberization: cut the fiber into short fibers with a length of 1~2mm;

[0029] 2) Drying: Dry the cut short fibers in an oven at 105°C until constant weight, and put them in an airtight container for later use;

[0030] 3) Weighing: Calculate the amount of polyester and cotton fibers that should be weighed according to the proportion of the planned configuration, and weigh with an infrared drying balance with a sensitivity of 0.0001g. Before weighing, you should also perform infrared drying twice Dry, so that the difference between the two weighings does not exceed 1%; put the weighed fiber in a glass container with a s...

Embodiment 2

[0037] The preparation of the standard sample of embodiment 2 wool and acrylic fiber

[0038] There are 19 content ratios of wool and acrylic fiber, which are 5 / 95, 10 / 90, 15 / 85, 20 / 80, 25 / 75, 30 / 70, 35 / 65, 40 / 60, 45 / 55, 50 / 50, 55 / 45, 60 / 40, 65 / 35, 70 / 30, 75 / 25, 80 / 20, 85 / 15, 90 / 10, 95 / 5, prepare two standard samples for each ratio.

[0039] 1) Cleaning: Wash the wool fibers in an aqueous solution of sodium dodecylbenzenesulfonate with a mass percentage of 5%, remove the grease on the wool, wash and dry;

[0040] 2) Short fiberization: cut the acrylic fiber and the washed and dried wool fiber into short fibers with a length of 1~2mm, and the cut wool fiber should be filtered in a 10-mesh sieve;

[0041] 3) Drying: Bake the filtered wool staple fiber and cut acrylic fiber in an oven at 105°C to constant weight. Make sure the sample is as dry as possible, put it in a closed container, and keep it for later use;

[0042] 4) Weighing: Calculate the amount of wool staple fiber a...

[0049] The preparation of the standard sample of embodiment 3 viscose glue and nylon fiber

[0050] A total of 19 content ratios of viscose and nylon fibers are 5 / 95, 10 / 90, 15 / 85, 20 / 80, 25 / 75, 30 / 70, 35 / 65, 40 / 60, 45 / 55, 50 / 50, 55 / 45, 60 / 40, 65 / 35, 70 / 30, 75 / 25, 80 / 20, 85 / 15, 90 / 10, 95 / 5, prepare two standard samples for each ratio.

[0051] 1) Cleaning: Wash the nylon fiber in an aqueous solution of sodium dodecylbenzenesulfonate with a mass percentage of 5%, remove the grease on the nylon fiber, wash and dry;

[0052] 2) Short fiberization: cut viscose fiber and cleaned nylon fiber into short fibers with a length of 1~2mm;

[0053] 3) Drying: Bake the cut viscose and nylon fibers in an oven at 105°C to constant weight. Make sure that the samples are as dry as possible, and put them in a closed container for later use;

Abstract

The invention discloses a preparation method of a sample with standard fiber component content. The preparation method comprises the following steps: 1) fiber shortening, 2) drying, 3) weighing, 4) evenly mixing and stirring, 5) filtering, 6) shaping, 7) pressing, 8) drying, 9) assigning a dried sample, labeling a name and a proportion of content of fiber, so that the fiber standard sample is obtained. According to the preparation method of the sample with the standard fiber component content, a sample of various fiber combinations can be prepared flexibly in a mass mode, cost of preparation of the sample is low, and operation method is simple. The prepared sample is accurate in fiber content, good in uniformity and shaping, and capable of being used as a standard sample for creating a model base fixed mold when the fiber component is measured by creating near infrared spectroscopy analysis, being used in a lab and used as a sample for detection quality control on the fiber component through a chemical dissolution method, being used as a standard sample for quality control on fiber samples such as cotton-hemp blended products and blended products by cashmere and woolens or special animal hairs, wherein the fiber samples cannot be quantified through the chemical dissolution method.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a method for preparing a small-batch and low-cost multi-component fiber component content standard sample combined in any proportion. Background technique [0002] In textile testing, in order to accurately determine the content of fiber components, it is necessary to compare the sample to be tested with the standard sample. At present, the production of standard samples is to mix different types of fiber strips according to a predetermined feeding ratio, and then rely on mechanical carding on mechanical equipment to achieve. Due to the different noils of various fibers in the process of mechanical carding, the difference between the fiber content of the final finished product and the predetermined feeding ratio is about 3~5%; moreover, a feeding in textile production is calculated in tons, while Less standard samples are required. Therefore, the above-mentioned method is no...
