Number of batch fiber packages
Number of joint sample packages
6.2 Sample preparationbzxz.net
6.2.1 Fiber breaking strength sample
Sampling requirements
Straighten the sample, align the base, cut 30mm from the middle of the test sample, and arrange it into a bundle of red fiber with uniform thickness. Weigh each bundle with a mass of 1.00g.
6.2.2 Fiber impurity content sample
Randomly take samples with a mass of about 1.00g from the laboratory sample. 30 fibers are used as samples. 6.2.3 Fiber regain test sample
Randomly select fibers with a mass of about 50g from the experimental empty samples as samples, seal them, and weigh the mass of the samples within 24 hours. 6.3 Test method
6.3.1 Appearance

7 Inspection rules
7.1 Inspection items
7.1.1 Pineapple leaf fiber shall be inspected according to all items specified in Chapter 5 of this standard. 2
NY/T2444-—2013
7.1.2 The fiber shall be shipped with an inspection report, which shall include the name, quantity and inspection results of the inspection items, the grade to be determined, the inspection unit, the inspector and the inspection conditions, the date, etc. 7.2 Determination rules
7.2.1 If all the inspection results meet the indicators in Table 1, it shall be determined to be qualified. 7.2.2 If one of the two indicators of fiber appearance quality and impurity content does not meet the requirements of the corresponding grade, it shall be downgraded by one grade. 7.3 Packaging quality
7.3.1 Determination of bale quality
The quality can be assessed by random sampling and weighing using a measuring instrument with a tip weight of 0.05kg that has been calibrated and qualified at the prescribed period. If the parties concerned have objections to the fiber quality, they can re-sample and measure the impurity content, moisture regain and actual mass of the fiber bales to calculate the nominal mass of the fiber bales. The mass of the entire batch of fibers is calculated by multiplying the nominal mass of each fiber bale by the number of fiber bales. The result is the nominal mass value of the batch of fiber bales. The nominal mass of each bale of the entire batch of fiber bales is expressed as the average value of all sample bales. The nominal mass of the fiber bales is calculated according to formula (1). 100+W× 100-F
W--standard weight, in dry grams (kg);
W--standard moisture regain, 13%;
actual moisture regain, in percentage (%); actual impurity content, in percentage (%); F
standard impurity content, in percentage (%). The value is accurate to one decimal place.
7.3.2 Determination of appearance dimensions
Use a qualified length measuring instrument such as a steel ruler (accuracy of 1mm) to randomly sample and measure the length, width and height of different parts of the six faces of the rectangular fiber package. Take at least 3 values for each item on each face and use the average value for analysis and evaluation. 8 Packaging, labeling, transportation and storage
8.1 Packaging
Each fiber package is composed of pineapple leaf fibers of the same variety, batch and grade. When packaging, the bases are clearly separated, straightened and neatly tied with galvanized iron wire or strapping tape after being shaped according to the specified length. Each package should be tied at least four times. The package quality and appearance dimensions should comply with the requirements of Table 3. Table 3 Requirements for the package quality and appearance dimensions of pineapple leaf fibers Item Month
8.2 Labeling
Package quality, kg
Each fiber package should be accompanied by a label, and the label content should include product mark, quality, production unit, production period, etc. 8.3 Transportation
Fibers should be kept clean, fireproof, rainproof and moistureproof during transportation. They should not be mixed with flammable, explosive and corrosive items. 8.4 Storage
Fibers should be stacked on indoor warehouse cushions according to their grades. They should be kept clean, dry and well ventilated to prevent them from getting wet. Fireworks are strictly prohibited. They should not be stacked with flammable, explosive and corrosive items.
