according toFZ /T 50010.3-2011viscose fiberThe standard for measuring the viscosity of pulp specifies the viscosityTest methods for viscosity of pulp for adhesive fibers - copper ethylenediamine solution method, copper amine solution capillary viscometer method, and polymerization degreeThe testing method.
Viscose fiber, abbreviated as viscose fiber or viscose filament,man-made fiberA type of regenerated fiber.Adhesive fiber is the main type of synthetic fiber.It is the second largest production of synthetic fibers in ChinaThe main raw material for viscose fibers is chemical pulp, including cotton pulp and wood pulp, which are later supplemented with materials such as bamboo pulp and cotton pulp. Natural cellulose is separated and regenerated through chemical reactions.Cotton wool pulp is the main type of synthetic fiber pulp in China, accounting for 87.5% of all pulp.
The use of adhesive fibers as chemical fibersUniversalregenerated fiberIts main characteristics include good spinnability, pure spinnability, and the ability to blend with various fibers; The fabric it makes has advantages such as drape, moisture absorption and breathability, good dyeing performance, anti-static, and UV resistance.
IVS400-6 Fully Automatic Viscometer
The Zhongwang Fully Automatic Viscometer IVS400 is designed with the Ubbelohde Viscometer as its core, complying with relevant standards such as ISO, GB, DIN, etc. It realizes fully automated testing processes such as automatic cleaning, automatic measurement, automatic calculation, automatic waste discharge, and automatic drying, and the timing accuracy can be precise within 0.001s. It provides a stable and uniform temperature field of ≤± 0.01 ℃ for testing, ensuring the accuracy of experimental data.
Test Process
Weighing samples
Weigh the cotton pulp sample with a one ten thousandth balance and place it in a dissolution bottle. Use a DP25 automatic liquid dispenser (with a transfer accuracy of ≤ 0.1%) to transfer the copper ethylenediamine solvent to the dissolution bottle;
Dissolve sample
Place the dissolution bottle into the P12 Zhongwang Polymer Dissolver (which can dissolve multiple samples simultaneously), and use magnetic stirring to dissolve the samples at the specified temperature and time;
Viscosity Test
Open IVS400 viscometer and set the desired water tank temperature (20 ℃/25)℃Add the solution to the Ubbelohde viscometer at ± 0.01 ℃, open the software for automatic testing and calculation, and the computer can automatically store the test data;
Test results
The IVS400 automatic viscosity tester is connected to the computer end, which can automatically obtain test results and store them for diversified viscosity data analysis;
The following figure shows the test data using cotton pulp as an example:
Clean the viscosity tube
After automatic waste disposal, add cleaning reagents for automatic cleaning and drying.
