Before the transferable agent transferring test, should handle fibrous structure sample to be measured according to Tappi method #T402OM-88.At this moment, pretreatment sample 24 hours under 10% to 35% relative humidity level and in 22 to 40 ℃ the temperature range.After this pre-treatment step, should under 48% to 52% relative humidity and in 22 ℃ to 24 ℃ the temperature range, handle sample 24 hours.Transferring test also should carry out in the room of steady temperature and humidity scope.
Then, from Cincinnati, the Cordage Inc. of Ohio buys the Crescent #300 cardboard of a slice 76cm (30 ") * 101cm (40 ").Six chip sizes that cut with a paper cutter out are the cardboard of 5.7cm * 18.4cm (2.25 " * 7.25 ").On the white side of cardboard, draw two and be parallel to short size and apart from top and the bottom maximal margin 2.9cm (line of 1.125 ").Use ruler as instructing the length that carefully marks described line with blade.Draw about full wafer thickness degree of depth of half approximately.This line can fit tightly around the counterweight of Sutherland Rub testing machine cardboard/felt combination.On this score side of cardboard, draw an arrow that is parallel to the long size trend of cardboard.
Then, six black felts (F-55 or equivalent, available from Bristol, the New England Gasket of Conn.) are cut into are of a size of 5.7cm * 21.6cm * 1.6cm (2.25 " * 8.5 " * 0.0625 ").Felt is placed on the uncrossed green side top of cardboard, makes the long edge of felt and cardboard parallel and in line.The fine hair side of guaranteeing felt up.(0.5 ") reaches outside the top and bottom maximal margin of cardboard also to allow about 1.3cm.Fibrous structure sample is cut into the size same with felt, and it is placed on the felt between two parties.The folding snugly edge that dangles, then sample and felt are glued (available from 3M, St.Paul, the Scotch.TM. adhesive tape of Minn. is suitable), finish the preparation of felt/cardboard/sample at cardboard behind.
1.8 kilogram (4 pounds) counterweight has 4cm 2(26cm 2) effective contact area, the contact that provides is pressed and to be 6.8kPa (1psi).Because contact pressure can be installed in the lip-deep rubber blanket of counterweight by replacing and changes, only adopt by manufacturer (Brown Inc., Mechanical ServicesDepartment, Kalamazoo, Mich.) Gong Ying rubber blanket is very important.If these pad hardening, wearing and tearing or cracked then must be changed.
When not in use, the gross weight that must make pad not support counterweight is placed counterweight.Counterweight preferably is sidelong preservation.
Measurement for actual tissue paper/cardboard combination is placed on transitional surface (glass mirror) on the base plate of tester, and mirror is placed against steady pin.Steady pin prevents that mirror from moving at test period.
To calibrate felt/cardboard/sample and be clamped on four pounds of counterweights, make paperboard side contact counterweight pad.Guarantee that cardboard/felt/thin paper combination is flat against counterweight.This counterweight is hooked on the tester arm.Felt/cardboard/thin paper sample must be put down and be leaned against on the mirror, and must 100% contact lense sub-surface.
And then, by pressing " push " pushbutton enable testing machine.When five strokes finish, testing machine will stop automatically.
Counterweight is taken off from the felt that is covered with cardboard.Check the thin paper sample.If torn, then abandon this felt and thin paper, restart then.If the thin paper sample is intact, then remove the felt that covers cardboard from counterweight.Other three the felt/cardboards of weight/thin paper sample guarantee that enough lotions have shifted to obtain accurate measurement result.
Repeat above-mentioned steps, each test condition is obtained six parallel results.
After all conditions has all been measured, remove and abandon all felts.Felt rug is not used again.The cardboard supporter uses their bendings always, tears, unable, or no longer have till the smooth surface.
Wash each mirror once with four milliliters of toluene aliquots, wash in the beaker.Extract is transferred in the sample flasket, used dried nitrogen drying then.With two milliliters of toluene aliquot washing mirrors for the second time, shift as mentioned above and dry described liquid.
Then in each sample flasket, adding one milliliter of toluene before the sealed vial.Stirring bottle then gently dissolves the mirror extract of transfer.Use known gas chromatographic method method to measure the content of transferable agent in the dissolving extract then.
Use this area known standard thing commonly used to determine the recovery constant of transferable agent (for washing and transfer step), and the equipment constant of definite gas chromatograph.
The transferable dosage that chromatography is determined is estimated transferable dosage on the mirror divided by reclaiming constant.The result is with the milligram record.
B. composition relative concentration method of testing is gone up on the surface
Can measure the relative concentration of composition on fibre structure and/or the thin page or leaf sanitary tissue products surface by using near infrared spectroscopy, if when particularly sample comprises hydrocarbonaceous compositions.Near infrared spectroscopy can use colourimetric photometer or other nir instrument, but it must be configured to the backscattering detection.Use suitable wavelengths.
Fibre structure and/or thin page or leaf sanitary tissue products are placed under the nir instrument, obtain a reading.The sample that overturns then obtains a reading from the another side of sample.
Except near-infrared, also can use mid-infrared light spectrometry with suitable equipment and wavelength, measure the relative concentration of composition on fibre structure and/or the thin page or leaf sanitary tissue products surface.
