Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of method of detection fibers water percentage and oil content.The method can be utilized the constant temp. heating weighing technology water percentage of detection fibers fast and accurately, and utilizes the nuclear magnetic resonance technique oil content of detection fibers fast and accurately, and the result degree of accuracy recording is high, reproducible.
To achieve these goals, the present invention adopts following technical scheme:
A method for detection fibers water percentage and oil content, comprising:
Step 1: with the constant temp. heating weighing Characteristics Detection fiber moisture of halogen moisture teller,
(a) with horizontal metroscope around getting POY fiber sample;
(b) POY fiber sample is put into halogen moisture teller and detect moisture, and the constant temperature oven oven drying method of result and GB regulation is compared;
Step 2: adopt direct oil dripping method on nuclear magnetic resonance spectrometer by nuclear-magnetism standard signal and oil content linear fit;
(a) simulation oil content test condition, by packing in the test tube of oil-containing without silk noil sample of certain mass, splashes into the spinning crude oil of concentration known;

Further, the concentration of spinning crude oil is 80%.
Further, be about 30s the detection time of fiber oil content each.
Adopt the method for detection fibers water percentage of the present invention and oil content, can record fast and accurately fiber moisture and oil content, and the result degree of accuracy recording is high, reproducible.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Step 1: with halogen moisture teller detection fibers water percentage,
(a) on horizontal metroscope around the POY fiber sample of getting five lot numbers, be respectively P110028, P110027, P130013, P130028, P110015;
(b) weigh tank of halogen moisture teller will be put into after the sample knotting winding, by the Temperature Setting of halogen Moisture Meter, it is 105 ℃, test duration can be set about 1 hour, during test, on instrument display, show water percentage always, when water percentage does not change (about 15min), stop test record water percentage, the constant temperature oven oven drying method of result and GB regulation is compared, experimental data is as shown in the table:
Step 2: adopt direct oil dripping method on nuclear magnetic resonance spectrometer by nuclear-magnetism standard signal and oil content linear fit;
