Quantitative chemical analysis
1 Scope
This standard specifies the chemical analysis of soybean protein fiber (with a polyvinyl compound) two-component mixture.
This standard applies to soybean protein fiber (with a polyvinyl compound) two component mixtures with certain other fibers.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research

GB/T 2910.1 Textiles - Quantitative chemical analysis - Part 1. General principles of testing (GB/T 2910.1-2009, ISO 1833-1.
2006, IDT)
3 soybean protein fiber and cotton, viscose, modal fibers, polyacrylonitrile fibers or two-component mixture of polyester fibers (hypochlorous acid
Sodium/hydrochloric acid method)
3.1 Principle
Sodium hypochlorite solution with 1mol L/soybean protein fiber in the soy protein is dissolved and removed from a known dry mass of the specimen,
With 20% hydrochloric acid solution and then the protein fiber remaining portion (polyvinyl formal) dissolved and removed, the residue was collected, cleared
Washing, drying and weighing, calculating its share of the dry mass of the mixture with a percentage of mass amended. Obtained by the difference of soybean protein fiber
The percentage of quality.
3.2 Reagents
Use GB/T 2910.1 and 3.2.1,3.2.2,3.2.3,3.2.4 provisions reagents.
Sodium hydroxide was added sodium hypochlorite solution 1mol/L in that its content of 5g/L. This solution can be iodometric titration so that its concentration
Degree in 0.9mol/L ~ 1.1mol/L.
3.2.2 hydrochloric acid solution (20% mass fraction)
Take 1000mL concentrated hydrochloric acid (20 deg.] C when density of 1.19g/mL) was slowly added to 800mL water, cooling to 20 ℃, plus
Water, amend its density 1.095g/mL ~ 1.100g/mL. Concentration at 19.5% ~ 20.5%.
3.2.3 in dilute acetic acid
Take 5mL glacial acetic acid diluted with water to 1000mL.
3.2.4 dilute aqueous ammonia solution
Take 80mL of concentrated aqueous ammonia (density 0.880g/mL), diluted with water to 1000mL.
3.3 Device
Use GB/T 2910.1 and 3.3.1,3.3.2 specified device.
3.3.1 stoppered Erlenmeyer flask with a capacity of 250mL.
3.3.2 water bath, maintaining the temperature at 20 ℃ ± 2 ℃.
3.4 Test procedure
According to GB/T 2910.1 prescribed generic procedure, and then follow the steps below.
The prepared sample into an Erlenmeyer flask, 100mL per gram of sample was added sodium hypochlorite solution (3.2.1) in a water bath (3.3.2) on
