Summary of the invention
The purpose of this invention is to provide and a kind ofly in yarn, soak into the method for testing of effect, can shoot slurries clearly and in yarn, soak into form, be used for testing the soak into situation of slurries at yarn based on the sem test slurries.
The technical scheme that the present invention adopted is, a kind ofly in yarn, soaks into the method for testing of effect based on the sem test slurries, specifically carries out according to the following steps:
Step 1: prepare to cut sizing section to be measured
1) gets a block rubber and block rubber is cut into cubic shaped;
Get sizing to be measured; Fineness according to sizing to be measured is selected sewing needle; The diameter of sewing needle for
wherein Ntex be the special number of sizing to be measured, the value of δ is 0.78 ~ 0.9;
Cutting sizing to be measured, the sizing to be measured that cutting is got off penetrates in the eye of a needle of sewing needle;
2) the sewing needle needle point that is installed with sizing to be measured in the eye of a needle is vertically thrust 1) in the upper surface of the block rubber processed; The pull sewing needle makes sewing needle carry the upper and lower surfaces that sizing to be measured passes block rubber; Because block rubber has curable grip to the sizing to be measured that penetrates wherein; The sizing to be measured that gets in the block rubber is clamped in block rubber, gets rid of the sewing needle of traction sizing to be measured;
Step 2: cut sizing section to be measured
1) with one group of movable jaw the block rubber two ends that are installed with sizing to be measured in the step 1 is fixed, prevented that block rubber from producing slippage;
2) get the sharp blade of a slice, the tail end of sizing to be measured that will pass the block rubber upper surface with blade is along block rubber upper surface flat cut, and removes the sizing that cuts with blade;
Step 3: make sizing section to be measured
1) unclamp one group of movable jaw, the clamping of taking off step 2 processing has the block rubber of sizing to be measured;
2) get microslide, with adhesive tape with 1) in clamping have the block rubber two ends of sizing to be measured to be fixed on the microslide, accomplish the preliminary making of sizing to be measured section;
3) with 2) in the sizing to be measured section that tentatively is made into be placed on and spray platinum under 10mA ~ 20mA electric current and handle, the time of spray platinum is 160 seconds ~ 200 seconds, promptly accomplishes the making of sizing section to be measured after platinum to be painted is accomplished, and obtains sizing section to be measured;
Step 4: the employing ESEM is taken the sizing photo and photo is stored in the computing machine
The sizing section to be measured of 1) step 3 being processed is put under the scanning electron microscope, the enlargement factor of adjustment scanning electron microscope, and enlargement factor is generally between 200 ~ 4000 times;
2) configure enlargement factor after, with scanning electron microscope to sizing to be measured section observe and take pictures, will take the sizing photo to be measured of getting well at last and be stored in computing machine and get final product.
Characteristic of the present invention also is,
The block rubber of making in the step 1 is a cube, is of a size of 10 * 10 * 2mm
3
The invention has the beneficial effects as follows,
The present invention characterizes the soak into situation of slurries in yarn with the traditional hand plotting method and is converted into and adopts ESEM directly to take the sizing cross-section photograph to obtain slurries soaking in yarn; Because the range of choice of ESEM enlargement factor is bigger; When taking, can choose flexibly according to the actual requirements and need amplification multiple; The quantity of taking pictures is also unrestricted; The captured sizing section photo that goes out is clear accurately to have improved sizing test accuracy and testing efficiency, for the detection of sizing quality provides a kind of more convenient, method more accurately.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
A kind ofly in yarn, soak into the method for testing of effect, specifically carry out according to the following steps based on the sem test slurries:
Step 1: prepare to cut sizing section to be measured
1) gets a block rubber and block rubber is cut into cubic shaped;
Get sizing to be measured; Fineness according to sizing to be measured is selected sewing needle; The diameter of sewing needle for
wherein Ntex be the special number of sizing to be measured, the value of δ is 0.78 ~ 0.9;
Cutting sizing to be measured, the sizing to be measured that cutting is got off penetrates in the eye of a needle of sewing needle;
2) the sewing needle needle point that is installed with sizing to be measured in the eye of a needle is vertically thrust 1) in the upper surface of the block rubber processed; The pull sewing needle makes sewing needle carry the upper and lower surfaces that sizing to be measured passes block rubber; Because block rubber has curable grip to the sizing to be measured that penetrates wherein; The sizing to be measured that gets in the block rubber is clamped in block rubber, gets rid of the sewing needle of traction sizing to be measured;
Step 2: cut sizing section to be measured
1) with one group of movable jaw the block rubber two ends that are installed with sizing to be measured in the step 1 is fixed, prevented that block rubber from producing slippage;
2) get the sharp blade of a slice, the tail end of sizing to be measured that will pass the block rubber upper surface with blade is along block rubber upper surface flat cut, and removes the sizing that cuts with blade;
Step 3: make sizing section to be measured
1) unclamp one group of movable jaw, the clamping of taking off step 2 processing has the block rubber of sizing to be measured;
2) get microslide, with adhesive tape with 1) in clamping have the block rubber two ends of sizing to be measured to be fixed on the microslide, accomplish the preliminary making of sizing to be measured section;
3) with 2) in the sizing to be measured section that tentatively is made into be placed on and spray platinum under 10mA ~ 20mA electric current and handle, the time of spray platinum is 160 seconds ~ 200 seconds, promptly accomplishes the making of sizing section to be measured after platinum to be painted is accomplished, and obtains sizing section to be measured;
Step 4: the employing ESEM is taken the sizing photo and photo is stored in the computing machine
The sizing section to be measured of 1) step 3 being processed is put under the scanning electron microscope, the enlargement factor of adjustment scanning electron microscope, and enlargement factor is generally between 200 ~ 4000 times;
2) configure enlargement factor after, with scanning electron microscope to sizing to be measured section observe and take pictures, will take the sizing photo to be measured of getting well at last and be stored in computing machine and get final product.
The captured sizing of the inventive method section picture picture is clear, helps improving the precision and the efficient of sizing test, for the detection of sizing quality provides a kind of new tool.Adopt the inventive method test slurries in yarn, to soak into effect, the enlargement factor adjustable extent is wide.
The operating procedure of the inventive method is simple; The requirement of the sizing section compound scan Electronic Speculum that cuts; Adopt ESEM the sizing serial section is observed and to be taken pictures, generally be impregnated between the fiber in the yarn when slurries, will make take place between the fiber mutual bonding; Because sizing does not have electric conductivity, increase electric conductivity so will handle, after the sizing slice surface carries out the metal spraying processing to sizing section carrying out metal spraying; Make the sizing surface that one deck conductive layer arranged; Through the section of the sizing behind the metal spraying, the section morphology of sizing just can taken and demonstrate to ESEM, through connecting computing machine; Can on the display of counter, observe slurries and whether be impregnated between the fiber, can judge the soak into situation of slurries in yarn thus.
