Example five: detection method
1. Height of foam
The pre-configured 100ml solution was mechanically foamed in a 500ml beaker, and the height of the foam in the beaker, measured in mm with a ruler after foaming was complete.
2. Half-life of foam
The pre-configured 100ml solution was mechanically frothed in a 500ml beaker with the foam half-life, measured in s, as the time taken from the first droplet appearing at the bottom of the beaker to the time when the liquid volume was half the original volume.
3. Hydrophilic property
With reference to GB/T24218 "test methods for textile nonwovens" section 6: measurement of absorbency the liquid absorption capacity was measured by using a YG814-II nonwoven fabric water absorbency measuring instrument.
The liquid penetration time, measured in s, was determined by means of a liquid penetration tester MB224B, according to FZ/T60017-1993 "liquid penetration test method for sanitary thin nonwovens".

Example six: foaming process verification
1. Temperature of foaming
Preselecting 100ml of distilled water, 20g/L of foaming agent and 20g/L of foam finishing agent in the third embodiment, stirring for 4min, rotating speed of 1500r/min, foaming in a 500ml beaker at different temperatures, exploring the influence of the temperature on the foaming performance, and measuring the foaming performance by different foam heights.
As a result, as shown in FIG. 1, the foam tends to increase in height in the beaker up to 25 ℃ and gradually decrease after 25 ℃. This is because the thermal movement between molecules in the solution increases at an elevated temperature, the activity of the foam increases, and the viscosity of the solution tends to decrease with increasing temperature. Therefore, on the premise of considering solution viscosity and foaming performance, 25 ℃ is selected as the optimal foaming temperature of the experiment.
2. Time of stirring
The foaming temperature of 25 ℃ is selected, other conditions are kept unchanged, and the influence of different stirring time on the foaming performance is measured by the foam height.
As a result, as shown in FIG. 2, the foam height increased before 6min and gradually decreased after 6min as the stirring time was increased. The reason is that as the stirring time is increased, the foam system is hollow, so that foam collapse is caused, the foam height is reduced, and the foaming performance is influenced, so that 6min is selected as the optimal stirring time.
3. Concentration of blowing agent
Selecting an anionic surfactant sodium dodecyl sulfate, selecting 25 ℃ as a foaming temperature, stirring for 6min, keeping other conditions unchanged, and measuring the influence of foaming agents with different concentrations on foaming performance by using the foam height.
As shown in FIG. 3, the foam height gradually increased with increasing blowing agent concentration and stabilized at about 2% concentration without significant increase. Therefore, a blowing agent concentration of 2% was chosen as the optimum concentration for this experiment.
4. Concentration of stabilizer
Selecting foaming temperature of 25 ℃, stirring time of 6min and 2% foaming agent concentration, keeping other conditions unchanged, and measuring the influence of the stabilizing agents with different concentrations on foaming performance by using foam half-life.
As shown in FIG. 4, the half-life time of the foam system without the stabilizer is very short, the foam half-life is prolonged with the increase of the concentration of the stabilizer, but the selected stabilizer is of a tackifying type, the concentration is too high, the foaming effect is influenced and even the foam can not be foamed, the foam half-life is about 60min enough for the fabric to be used in the after-finishing, and the foam system is still fine in the half-life time. Therefore, under the large trend of energy conservation and emission reduction, in order to save reagents while considering foam stability, the stabilizer with the concentration of 1% is selected as the optimal dosage of the experiment.
Example seven: hydrophilic soft foam finishing single factor verification test
The surface layer of the sanitary material is SSS spunbonded polypropylene fiber non-woven fabric with the gram weight of 15g/m2。
1. Concentration of finishing agent
According to the optimal foaming process of the first embodiment, the finishing agent of the third embodiment is selected, the concentration range of the finishing agent is 0.3-1.5%, a rolling foam process (double-sided rolling foam) is adopted, the pre-drying temperature is selected to be 80 ℃ (2 min), the drying temperature is selected to be 115 ℃ (3 min), hydrophilic soft finishing is carried out on SSS spunbonded nonwoven fabrics, and the influence of different concentrations of the finishing agent is measured by the liquid absorption capacity and the liquid penetration time respectively.
As a result, as shown in FIG. 5, the liquid absorption amount increased with the increase of the concentration of the finishing agent and became gentle after 0.6% concentration, so that the concentration of the finishing agent is preferably 0.6% or more. The liquid penetration time decreases with increasing concentration of the finish and increases after 1% concentration. This is because the finish is adsorbed onto the fabric surface primarily by dispersion forces and gradually becomes saturated on the fabric surface as the finish concentration increases, and as the finish concentration increases, the absorbent layer thickens and the liquid penetration time increases. Therefore, the concentration range of the selected finishing agent is 0.8-1.0%.
2. Baking temperature
The pre-drying temperature is selected to be 80 ℃ (2 min), the drying time is 3min, the concentration of the finishing agent is selected to be 1%, and the influence of different drying temperatures on hydrophilic finishing of the SSS spunbonded nonwoven fabric is measured by the liquid absorption and the liquid penetration time.
As a result, as shown in fig. 6, the liquid absorption of the SSS spunbond nonwoven fabric gradually increased and then tended to be gentle and decreased as the baking temperature increased, because the intermolecular bonding force was active under the appropriate temperature condition, and the molecular activity was decreased by the excessively high temperature. From the perspective of liquid penetration time, the liquid penetration time gradually decreases with increasing temperature at a baking temperature of 80 ℃ to 120 ℃, particularly significantly decreases from 110 ℃ to 120 ℃, and slightly increases after 120 ℃, because the adsorption of the surfactant on the surface of the SSS spunbond nonwoven fabric is affected by temperature, and the finishing agent may be decomposed at a further increase in temperature, thereby extending the liquid penetration time. The baking temperature is comprehensively considered, and the range of 110-120 ℃ is selected to be more suitable.
3. Baking time
The hydrophilic finishing effect of different baking times on SSS spunbond nonwovens was measured in liquid uptake and liquid penetration time, as above, at a baking temperature of 120 ℃, also in other conditions.
As a result, as shown in fig. 7, the liquid uptake of hydrophilic finished SSS spunbond nonwoven does not differ much within a reasonable baking time, whereas from the liquid penetration time point of view, the liquid penetration time gradually shortens and flattens as the baking time increases, because the evaporation of water tends to be complete as the baking time increases, so that the finishing effect does not differ much later. Therefore, the baking time is selected to be 2-4 min in consideration of energy consumption.
Example eight: orthogonal experimental validation analysis
The surface layer of the sanitary material is SSS spunbonded polypropylene fiber non-woven fabric with the gram weight of 15g/m2。
1. As shown in tables 1, 2 and 3, the performance of samples of different experimental process combinations was tested, and finally the optimum process conditions for hydrophilic soft finishing of the finish were obtained by experimental data analysis.

Computing，
(2) Calculating the range R1, R2 and R3
The size of the range difference is the difference value corresponding to the maximum value and the minimum value. The magnitude of the range R reflects the magnitude of the influence degree of the corresponding factors on the experimental result. A larger value of R1 indicates a greater degree of influence of its corresponding level on the amount of liquid absorbed; a larger value of R2 indicates a greater degree of influence of its corresponding level on the liquid penetration time; rA larger value of 3 indicates a larger degree of influence of the corresponding level on the stiffness. As can be seen from the table, the order of the degrees of influence of the factors on the experiment is as follows: concentration of hydrophilizing agent
Baking timeAnd (4) baking temperature.
2. Determination of optimal solution
The optimal solution of the liquid absorption amount is A according to the visual analysis3B2C2The optimal solution of the liquid penetration time is A3B2C2The optimal stiffness scheme is as follows: a. the3B2C2I.e. a finish concentration of 10g/L, a baking time of 3min, at a baking temperature of 115 ℃, the liquid uptake of the SSS spunbond nonwoven reaches a maximum, while the liquid penetration time is shortest and the stiffness is smallest. Therefore, the optimal scheme of the experiment is determined to be that the concentration of the finishing agent is 10g/L, the baking time is 3min, and the baking temperature is 115 ℃.
3. Comparison of Performance before and after finishing of SSS spunbonded nonwoven
TABLE 4 SSS spunbonded nonwoven before and after finishing Performance comparison Table
The data analysis in Table 4 shows that the hydrophilic performance of SSS spunbonded nonwoven fabric finished by the TF-629A finishing agent is obviously improved, the stiffness is reduced to some extent, the hand feeling of the material is softer, the material meets the related performance requirements in FZ/T64005-2011 sanitary thin nonwoven fabric, and the SSS spunbonded nonwoven fabric can be used as a surface layer coating material of paper diapers.
4. Stability of hydrophilizing agents in SSS spunbond nonwovens
The results of multiple liquid penetration time tests for different volume fractions of TF-629A foam finished SSS spunbond nonwoven are shown in table 5:
TABLE 5 multiple liquid penetration time test chart for hydrophilizing agent with different concentrations
As can be seen from Table 5, due to the foam-finished SSS spunbond nonwoven fabrics with different concentrations of TF-629A finishing agent, the hydrophilic agent was considered not to migrate and the durability and stability were satisfactory if the sum of the 3 liquid penetration times measured for the samples was not much different.
5. Compared with the traditional padding process, the foam finishing process
TABLE 6 comparison of different finishing processes
Mangle ratio = (weight of rolled sample-original weight of sample)/original weight of sample x 100%
Saving reagent percentage = (weight gain of sample after traditional dipping rolling-weight gain of sample after foam rolling bubble)/weight gain of sample after traditional dipping rolling x 100%
As can be seen from the data analysis in Table 6, compared with the traditional padding process, the foam finishing process saves 33.3 percent of reagents, reduces the mangle expression by 60 percent, and has obvious energy-saving and consumption-reducing effects, so that the foam finishing process has great superiority compared with the traditional padding process.
Example nine: effect of Soft hydrophilic finish on the physical and mechanical Properties of fabrics
In order to study other property changes of the samples after finishing of the hydrophilic soft foam, the results of the physical mechanical property and air permeability test on the SSS spunbonded nonwoven fabric finished by the optimal scheme in example eight are as follows:
TABLE 7 physical-mechanical Properties and air permeability of the finished SSS spunbonded nonwoven
The SSS spunbonded polypropylene fiber non-woven fabric subjected to hydrophilic soft foam finishing is reduced in breaking strength, breaking elongation and air permeability, but the reduction degree is not large, and the relevant technical requirements of product standards can be still met.
While the present invention has been described in detail with reference to the drawings and the embodiments, those skilled in the art will understand that various specific parameters in the above embodiments can be changed without departing from the spirit of the present invention, and a plurality of specific embodiments are formed, which are common variation ranges of the present invention, and will not be described in detail herein.
