Problems solved by technology

However, due to the simultaneous use of monohydric alcohols as accelerators, although the solubility of calcium chloride salt solution to silk fibroin fibers is improved, it also enhances the solubility of fibers with amide structures such as nylon, thereby limiting the solubility of mulberry. Quantitative analysis of fiber components in textiles such as silk / nylon, narrowing the scope of application of the method
Moreover, the monohydric alcohol aqueous solution is easy to volatilize during the heating process, which is easy to cause the change of the solution composition and affect the dissolution efficiency; it also deteriorates the working environment.

Embodiment 1

[0017] The sample that the required quantitative analysis inspection of present embodiment is through qualitative analysis is the mixed silk cotton sample of the different proportions of mulberry silk (Jiangsu Hai'an) and tussah silk (Liaoning), it is carried out quantitative analysis inspection, referring to accompanying drawing 1, by this implementation As can be seen in the flow chart of the quantitative analysis method of the two-component fiber textile containing mulberry silk, its concrete steps are as follows:

[0018] (1) Sample pretreatment (recombination)

[0019] The purpose of sample pretreatment (refining) is to remove the ash, grease and residual sericin on the silk cotton. Cut about 5.0g of the qualitatively analyzed sample, put it into a beaker, and add 2.0g of L -1 Anhydrous sodium carbonate and 4.0gL -1 Synthetic detergent solution, bath ratio is 1:80. Heat to 95°C in a constant temperature water bath, stir once every 10 minutes, and keep warm for 1 hour. ...

Embodiment 2

[0032] In this example, a commercial mulberry silk / nylon two-component blended fabric is used, and the specific steps and other conditions of its quantitative analysis are as described in Example 1.

[0033] Table 2 is the result of the quantitative analysis test of the mulberry silk / nylon two-component blended fabric in Example 2.

[0034] Table 2

[0035]

[0036] The test results in Table 2 show that the nylon component has good solubility resistance in the solution, and its fiber mass loss rate is low. The measured value is in good agreement with the theoretical value, and the reliability is high. The method overcomes the disadvantage of weak solvent resistance of the nylon component in the traditional calcium chloride alcohol solution, and expands the scope of application of the method, so it can be widely used in the quantitative analysis and testing of mulberry silk / nylon textiles.

Embodiment 3

[0038] In this example, a commercial mulberry silk / wool two-component blended fabric is used, and the specific steps and other conditions of its quantitative analysis are as described in Example 1.

[0039] Table 3 is the result of the quantitative analysis test of embodiment three pair of mulberry silk / wool two-component blended fabrics.

Abstract

The invention discloses a method for quantificationally analyzing and detecting the components of a textile, in particular to a method for quantificationally analyzing the double-component fiber textile containing mulberry silk. The invention belongs to the textile detection technical field and comprises the following steps that: the sample which is quantificationally analyzed is preprocessed, the mulberry silk component in the sample is dissolved and is eliminated by the water solution of calcium nitrate with a mol ratio of 1:7 to 14; after the fiber component which is not dissolved is separated, the fiber component which is not dissolved is washed, dried, cooled and measured to determine the component, according to the mass difference between the sample before the dissolution and the fiber component which is not dissolved, the content of the mulberry silk component is determined. The method is suitable for the quantificational analysis of the mulberry silk, the other protein components and the nonprotein components and has the advantages of accurate test result, wide applicability, convenient operation, safe and non-toxic property and environment protection.

Description

technical field [0001] The invention relates to a method for quantitative analysis and inspection of textile components, in particular to a method for quantitative analysis of bicomponent fiber textiles containing mulberry silk, and belongs to the technical field of textile inspection. Background technique [0002] Bi-component and multi-component fiber textiles made of two or more fiber materials through blending, blending, interweaving, etc., can overcome the weakness of a single fiber material itself, fully integrate the advantages of multiple fibers, and greatly improve the quality and durability of textiles. The wearability and functionality of textiles are improved, and the excellent appearance and style that cannot be obtained by single-component textiles can be obtained at the same time, which greatly enriches the variety of market products. In particular, bicomponent fiber textiles containing natural mulberry silk (such as mulberry silk / tussah silk, mulberry silk / ny...
