Abstract

A provided quantitative determination method for fiber content of viloft fiber and natural cellulose fiber blended textiles comprises the following steps: S1, putting viloft fiber and natural cellulose fiber blended textiles in a baking box to bake to dry, then cooling to room temperature, and weighing the mass of the blended textiles, wherein the natural cellulose is cotton, flax and ramie which are not subjected to chemical degradation; S2, putting the blended textiles in a formic acid-zinc chloride reagent with the formic acid mass fraction of 68% and the zinc chloride mass fraction of 20% according to the sample (g) to reagent (mL) bath ratio of 1:100-200, continuously shaking at 40-70 DEG C for 20-60 min; and S3, washing fiber indissolvable in the formic acid-zinc chloride reagent in the step S2 with water to neutral, putting in a constant-temperature baking box to bake to dry, rapidly taking out and cooling to room temperature, and weighing the residual mass of the blended textiles. A detection result is highly consistent with an actual value, and the method has extremely high accuracy.

Description

technical field

[0001] The invention relates to a method for quantitative analysis and detection of fiber content in textiles, in particular to a method for detection of blended products containing viloft fibers and natural cellulose. Background technique

[0002] Viloft fiber, commonly translated as Viloft fiber or Viloft fiber in Chinese, is another new type of regenerated cellulose fiber produced by British Acordis company after Tencel fiber. It is artificially extracted from high-quality wood specially cultivated ecologically. The raw materials are extracted and produced by the solvent method, which is a pure natural, high-grade environmental protection, pollution-free and degradable fiber. The production process of viloft fiber will not pollute the environment. The auxiliary materials and additives used in the production process are non-toxic, and most of the auxiliary materials and semi-finished fibers can be recycled. It is a new type of green and environmentally frie...
