Abstract

The invention relates to the technical field of fiber content analyzing, in particular to a sisal hemp leaf fiber content rapid measurement method. The sisal hemp leaf fiber content rapid measurementmethod comprises the steps that S1, an about 15 cm-25 cm transverse middle section part is chosen in a to-be-measured sisal hemp leaf, the side edge of the about 15 cm-25 cm transverse middle sectionpart is cut off, a section of cuboid sisal hemp leaf section is obtained and serves as a sample; S2, the longitudinal area and the transverse length of the sample are measured through CCD image collecting and by using a photoelectric area method; S3, the tension and the elongation of the sample is measured through a tension testing machine, and a young modulus of the sample is obtained; and S4, function relationship of the young modulus of the sample and the fiber content of the sample is utilized, the fiber content of the whole leaf is represented by the fiber content of the sample, and thusthe fiber content of the to-be-measured sisal hemp leaf is measured. According to the sisal hemp leaf fiber content rapid measurement method, the relationship between the young modulus and the fiber content of the representative part of the leaf is researched, the fiber content of the to-be-measured sisal hemp leaf is judged through the young modulus method, and the measuring method is simple, fast and environmental friendly.

Description

technical field [0001] The invention relates to the technical field of fiber content analysis, in particular to a method for rapidly measuring the fiber content of sisal leaves. Background technique [0002] Sisal fiber is a kind of natural hard fiber obtained from the vascular bundle fibers in sisal leaves. It has many characteristics such as long fiber, white color, tough texture, strong tensile force, acid and alkali resistance, friction resistance, seawater corrosion resistance, etc. It is mainly used to manufacture ropes, linen, carpets, polishing wheels and other products. Important materials in sectors such as navigation, industry, and forestry are renewable resources. The scientific, accurate, stable, rapid and environmentally friendly method for measuring the fiber content of sisal leaves can not only standardize the production management of sisal leaves, but also provide an effective reference for the production and scientific research of the sisal industry.
