[0002] In recent years, many water-absorbing and quick-drying fabrics have appeared on the market. For example, patent document CN109385737B discloses a water-absorbing and quick-drying knitted fabric, which specifically discloses that the knitted fabric is a single-sided knitted fabric, including a surface layer and an inner layer with a concave-convex structure. At the same time, there are ventilation holes on the fabric, and the size of the ventilation holes is 5×10 3 μm 2 ~30×10 3 μm 2 , it can keep the skin dry even when sweating a lot, and it is well breathable.

[0003] For example, patent document CN105986358A discloses a water-absorbing and quick-drying knitted fabric, which specifically discloses that the knitted fabric is a single-sided knitted fabric, the back of which has a concave-convex structure, and the height of the convex part of the concave-convex structure is 40 to 150 μm. The fiber forming the convex part is a polyester elastic fiber, which has a light texture and excellent water-absorbing and quick-drying properties.

[0005] However, none of the above patent documents solves the problem of water retention of fabrics and the problem that the transverse water absorption diffusion length is longer than the longitudinal one, and thus the application fields are greatly limited.

[0024] The knitted fabric of the present invention has a ribbed structure on only one side, with grooves between adjacent ribs. The direction parallel to the ribbed extension is defined as the longitudinal direction, while the direction perpendicular to the ribbed extension is defined as the transverse direction. The weave of the knitted fabric of the present invention is not particularly limited and can be selected as needed, as long as the ribbed structure is formed on one side. In the present invention, the weave is preferably a variable plain stitch. This variable plain stitch is composed of a combination of looped and floated yarns, with at least three consecutive wales of floated yarns knitted to form a hollow ribbed structure. When a liquid is dropped onto the ribbed surface, diffusion is significantly less hindered in the longitudinal direction than in the transverse direction, resulting in a significant diffusion advantage. When a liquid is dropped onto the other side, the hollow structure at the base of the ribs reduces the number of channels for liquid diffusion in the transverse direction, while maintaining the longitudinal diffusion channels. This significantly improves diffusion. Therefore, the fabric of the present invention achieves a longitudinal water absorption and diffusion length greater than the transverse length on both sides. In the present invention, the rib height h, rib width a, and groove width b satisfy the following relationship: 1.0 ≤ h / (a + b) ≤ 8.0, more preferably 1.0 ≤ h / (a + b) ≤ 3.0. If h / (a+b) is less than 1.0, the difference in water absorption diffusion length between the longitudinal and transverse directions is not obvious, that is, the advantage of unidirectional liquid diffusion is not obvious, and the water retention is poor; if h / (a+b) is greater than 8.0, no matter which side is used as the skin surface, the comfort will be reduced, especially after the convex strips absorb the liquid, the wet feeling will be aggravated, and a sticky feeling will be produced, and the dryness will be poor.

[0025] Preferably, the groove width b and the ridge width a satisfy the following relationship: 1.0 ≤ b / a ≤ 12.0, more preferably 1.0 ≤ b / a ≤ 7.0, and most preferably 1.0 ≤ b / a ≤ 3.0. If b / a is less than 1.0, the number of channels for liquid diffusion in the longitudinal direction per unit area decreases, and the difference in water absorption diffusion length between the longitudinal and transverse directions tends to decrease, so this is not preferred. If b / a is greater than 12.0, liquid diffuses primarily in the grooves, and the difference in water absorption diffusion length between the longitudinal and transverse directions tends to decrease, so this is not preferred.

[0026] Preferably, the ridge height h is 1000-10000 μm, more preferably 1000-5000 μm, and most preferably 1000-3000 μm. When the ridge height is less than 1000 μm, the water retention of the fabric tends to decrease, so it is not preferred. When the ridge height is greater than 10000 μm, the overall thickness of the fabric increases, which may affect wearing comfort, so it is not preferred.

[0027] Preferably, the ridge width a is 100-5000 μm, more preferably 100-2000 μm, and most preferably 500-1000 μm. When the ridge width is less than 100 μm, the ridges are closely arranged, the ridge structure surface is close to the appearance of a plain stitch, and the difference in water absorption diffusion length between the longitudinal and transverse directions tends to decrease. When the ridge width a is greater than 5000 μm, the water retention capacity of the fabric tends to decrease, and reverse osmosis may occur.

[0028] Preferably, the groove width b is 100 to 5000 μm, more preferably 100 to 2000 μm, and most preferably 500 to 1100 μm. When the groove width is less than 100 μm, the channels for liquid to diffuse longitudinally on the non-convex stripe surface are reduced, and the difference in water absorption diffusion length between the longitudinal and transverse directions tends to decrease. When the groove width is greater than 5000 μm, the number of ridges per unit length decreases, which may affect the water retention of the fabric.

[0029] Knitted fabric of the present invention is made up of hydrophilic fiber and hydrophobic fiber, and preferably, the fiber of ribbed structure of the present invention is hydrophilic fiber.The hydrophilic fiber here is the fiber with hydrophilic property itself or the fiber with hydrophilic resin attached to the surface, preferably the fiber with hydrophilic property itself, such as cotton fiber in natural fiber, viscose fiber, modal fiber etc. in regenerated cellulose fiber, polyamide fiber etc. in synthetic fiber, more preferably cotton fiber or viscose fiber.The hydrophobic fiber here is the fiber without hydrophilic property itself or the fiber with water-repellent resin attached to the surface, preferably the fiber without hydrophilic property itself, such as one or more in polyethylene terephthalate fiber (PET), polybutylene terephthalate fiber (PBT), polypropylene terephthalate fiber (PTT), cationic dyeable polyester fiber (CDP), polypropylene fiber (PP), spandex (PU) etc., preferably at least containing PET fiber, more preferably at least containing PET fiber and spandex.The form of fiber used in the present invention is not particularly limited, can be filament or staple yarn, select as needed.

[0030] As a preference, the knitted fabric of the present invention has a longitudinal and transverse water absorption diffusion length ratio of 1.2 or more and a water retention capacity of 700 g / m 2 More preferably, the longitudinal and transverse water absorption diffusion length ratio is 1.5 or more and 3.0 or less, and the water retention capacity is 900g / m 2 Above 3000g / m 2 the following.

[0031] The knitted fabric of the present invention can be a plain fabric or a colored product. The colored product can be obtained by knitting with colored yarn or by dyeing the plain fabric.

[0032] The sanitary product of the present invention comprises at least a leak-proof part, which comprises at least a waterproof layer, a water absorption and diffusion layer and a skin layer. The water absorption and diffusion layer comprises at least the aforementioned knitted fabric, and the convex strip structure of the knitted fabric faces the waterproof layer.

[0033] The sanitary product of the present invention may be a sanitary pad or a breast pad consisting only of a leak-proof component, or may be a sanitary underpants consisting of a leak-proof component and a body, etc., without particular limitation.

[0034] The muscle surface layer here is the surface layer that contacts the skin and plays a role in rapid penetration. Preferably, the muscle surface layer is a waterproof fabric with a static contact angle (static contact angle with water) of 90° to 180° on at least one side. The muscle surface layer can be a waterproof mesh fabric or a waterproof non-mesh fabric. More preferably, the waterproof mesh fabric is a mesh fabric with a static contact angle of 130° to 180° on at least one side; the waterproof non-mesh fabric is a non-mesh fabric with a static contact angle of 90° to 130° on at least one side. The structure of the non-mesh fabric can be ordinary plain stitch, variable plain stitch, etc. Most preferably, the muscle surface layer is a waterproof mesh fabric with a static contact angle of 130° to 180° on both sides. This can ensure that moisture penetrates into the next layer and prevent the absorbed liquid from back-seeping into the muscle surface layer due to external force squeezing, thereby reducing the reverse seepage rate of the product and improving the dryness of the muscle surface. The waterproof fabric is not particularly limited and may be a fabric obtained by padding with a water repellent. Examples of the water repellent include silicone compounds, hydrocarbon compounds, and the like.

[0035] Generally speaking, the thicker the muscle surface layer, the stronger its liquid absorption capacity, and the easier it is for liquid to be stored in the muscle surface layer. However, when external force is applied, the liquid stored in the muscle surface layer may be squeezed out, affecting the wearing experience. Therefore, the present invention preferably adopts a weight of 60-130 g / m 2 Waterproof fabric, which can reduce the reverse seepage rate.

[0036] Adjacent to the skin layer is a water absorption and diffusion layer. This layer may be composed solely of the knitted fabric of the present invention, or a combination of the knitted fabric of the present invention and a nonwoven fabric. Preferably, the layer is composed solely of the fabric of the present invention. While a combination of the knitted fabric of the present invention and a nonwoven fabric improves water absorption, it increases the thickness of the sanitary product, potentially causing discomfort and is therefore not preferred.

[0037] Preferably, the convex strip structure surface of the knitted fabric of the present invention faces the waterproof layer, so that wearing comfort can be ensured.

[0038] Preferably, at least one of the front surface layer and the water-absorbing and diffusing layer has a bacteriostatic activity value greater than 2.2 according to the JIS L 1902:2015 bacterial liquid absorption method. Antimicrobial properties can be achieved through the use of antimicrobial fibers or antimicrobial finishing. Antimicrobial fibers are obtained by spinning ceramic powders containing silver, etc., mixed into polymers. Antimicrobial finishing involves padding or bath treatment with antimicrobial agents such as quaternary ammonium salts.

[0039] To improve motion tracking, the waterproof layer is preferably a coated or film-coated fabric with a warp elongation between 30% and 100%. The coated fabric is not particularly limited and can be a single-sided coated fabric coated with a resin such as polyurethane (PU) or polytetrafluoroethylene (PTFE). The film-coated fabric is also not particularly limited and can be a single-sided film-coated fabric with a PU or TPU film. The coated or film-coated surface of the waterproof layer is adjacent to the water absorption and diffusion layer.

[0040] Preferably, the water absorption rate of the skin surface of the leakage-proof part is greater than 1.0 ml / s, and more preferably the water absorption rate is greater than 5.0 ml / s, so as to ensure the dryness of the skin surface and effectively prevent side leakage.

[0041] Preferably, the water absorption of the leak-proof component of the present invention is 15 to 50 g / 100 cm 2 .

[0042] The leak-proof component of the present invention can be sewn using an outwrapping method to prevent liquid from leaking from the side. Preferably, the leak-proof component of the present invention has a reverse osmosis rate of less than 5.0%, which has an excellent anti-reverse osmosis effect.

[0043] The present invention will be further described below with reference to the following embodiments and comparative examples.

[0044] The test methods for the various parameters involved in the present invention are as follows:

[0045] (1) Rib height, rib width, groove width

[0046] First, cut three 1.0cm*0.5cm fabric samples in a direction perpendicular to the direction of the ridges, following the fabric's weave. Next, take one of the samples and affix it to a metal convex sample table in a natural, tension-free state (the fabric's ridges extend perpendicular to the surface of the convex sample table). Then, use a KEYENCE VHX-2000C microscope to observe the cross-section of the sample. Specifically, adjust the microscope magnification to 50x, perform a depth synthesis of the observed area, and display it in 3D. Select one of the ridges and find the outer sides of the connecting coils between its bottom ends and the non-ridged parts on both sides. The straight-line distance a between the outer sides of the two connecting coils is the ridge width; the straight-line distance b between two adjacent ridges is the groove width. The extension line of the ridge width a is line e. Then, select the highest point of the ridge, and the perpendicular distance between it and line e is the ridge height h. Using this method, 10 locations on the cross-section of the fabric sample were measured, yielding one set of data for ridge width, one set for groove width, and one set for ridge height. The two largest and two smallest values ​​in each set were removed, yielding the six values ​​in the middle. The average of each set was then calculated. The remaining two fabric samples were measured and calculated using the same method, and the average of the data from the three samples was taken as the ridge width a, groove width b, and ridge height h of the present invention.

[0047] (2) Ratio of longitudinal and transverse water absorption diffusion lengths

[0048] The direction parallel with the ribbed stripe direction of extension is vertical, and the direction perpendicular to the ribbed stripe direction of extension is horizontal.From fabric, cut 3 of the 18cm*24cm (horizontally * vertical) swatches, get 1 swatch wherein and 3mL three-level water is dripped on the non-ribbed stripe structure surface (dropper vertically contacts fabric when dripping, does not apply pressure, all dripped in 1 second), after 10 minutes, measure the diffusion length in the vertical direction with a graduated ruler and be designated as M, the diffusion length in the horizontal direction and be designated as N, calculate ratio M / N.If the diffusion length is unclear, the mixed solution after available 0.1g dyestuff and 20mL water mix is ​​replaced three-level water.According to the same method, remaining 2 swatches are measured, obtain 3 groups of data and average as the vertical and horizontal water absorption diffusion length ratio of the present invention.

[0049] (3) Water retention ratio of inside and outside

[0050] a. Take three 10cm*10cm cloth samples, six filter papers of the same size, and one piece of plexiglass of the same size;

[0051] b. Adjust the temperature and humidity for 24 hours at a temperature of 20±2℃ and a humidity of 65±4%;

[0052] c. First weigh the weight of the organic glass (W0) and a piece of sample cloth (W1) (keep three decimal places), then use a syringe to measure 1mL of tertiary water and place it on the organic glass, and quickly place the weighed sample cloth on the water (the non-convex stripe structure surface contacts the water). After leaving it for 1 minute, weigh the weight of the sample cloth after absorbing water (W2) (keep three decimal places), weigh the weight of the organic glass after absorbing water (W3) (keep three decimal places); weigh the weight of the two pieces of filter paper before absorbing water (w1, w3) (keep three decimal places). Next, place the sample cloth after absorbing water (with the non-convex stripe structure surface as the surface, placed surface down) in the middle of the two pieces of filter paper mentioned above, and place a 500g weight on it. After leaving it for 1 minute, directly weigh the weight of the surface filter paper and the inner filter paper (w2, w4) (keep three decimal places), and calculate the surface and inner water retention rate ratio (keep one decimal place) using the following formula.

[0053] Surface water retention (%) = (w2-w1) / (W2-W1)×100

[0054] Internal water retention rate (%) = (w4-w3) / (W2-W1)×100

[0055] Surface water retention ratio = surface water retention (%) / inner water retention (%)

[0056] W1: Weight of the sample cloth before absorbing water (g)

[0057] W2: Weight of the sample fabric after absorbing water (g)

[0058] w1: Weight of filter paper before absorbing water (g)

[0059] w2: Weight of the filter paper on the surface after absorbing water (g)

[0060] w3: Weight of the filter paper before absorbing water (g)

[0061] w4: weight of the filter paper inside after absorbing water (g);

[0062] d. Measure the remaining two pieces of fabric samples according to the method of step c, and take the average value as the surface and inside water retention ratio of the present invention.

[0063] (4)Water retention capacity

[0064] The direction parallel to the ridges is the longitudinal direction, and the direction perpendicular to the ridges is the transverse direction. Take three 6cm x 27cm (width x length) fabric swatches. The swatches should be smooth and wrinkle-free. Place the swatches under standard atmospheric pressure to equilibrate the moisture. Weigh the original weight of each swatch (m1) (round to three decimal places). Place one of the swatches in a container of grade tertiary water. Allow the swatch to sink naturally after absorbing the water. If the swatch does not sink naturally, press the swatch into the water and then lift it up, repeating this process 2-3 times. After the swatch is fully immersed in water for 10 minutes, remove it and hang it flat vertically (clamp it horizontally and let it droop vertically). Allow the water to drip naturally. Observe carefully. When the swatch stops dripping, immediately remove it with tweezers and weigh the swatch (m2) (round to three decimal places). Note: The swatch is considered to be dripping-free if the interval between two drops of water is at least 30 seconds. The water retention of the sample cloth is calculated (accurate to an integer) using the following formula: Water retention (g) = m2 - m1. Measure the remaining two samples of cloth in the same way, and take the average value as the water retention of the present invention.

[0065] (5) Elongation

[0066] The waterproof layer was removed from the leak-proof component and tested according to the elongation D method of JIS L 1096:2010.

[0067] (6) Antibacterial activity value

[0068] The knitted fabric in the water absorption and diffusion layer of the leak-proof component was removed and tested according to the JIS L 1902:2015 bacterial liquid absorption method.

[0069] (7) Static contact angle

[0070] Remove the surface layer from the leak-proof component and perform the sessile drop test. Cut a 5cm x 5cm fabric swatch and use a LAUDA contact angle meter to measure three random locations on one side of the swatch. Ensure the droplet is dripped within 5 seconds of measurement. Obtain three readings and take the average value as the static contact angle for one side of the fabric of this invention.

[0071] (8) Water absorption rate

[0072] Disassemble the leak-proof component and cut three 10cm*10cm fabric swatches from each layer, i.e., three sets of fabric swatches. Take one swatch from each layer and stack them according to the order of the layers in the sanitary product. Wrap the swatches with waterproof tape, 0.5cm from each edge. Then, add 5ml of grade tertiary water dropwise at a height of 1cm from the surface of the muscular layer (skin side). The time from the moment the water droplet contacts the fabric surface until it disappears from the fabric surface is recorded as T. The ratio of the 5ml (5g) of water added to the time it takes for the liquid to be absorbed is the water absorption rate, calculated as follows: Water absorption rate (ml / s) = 5 / T. Measure the water absorption rate of the remaining two sets of fabric swatches using the same method, and take the average value as the water absorption rate of the present invention.

[0073] (9) Reverse osmosis rate

[0074] Disassemble the leak-proof parts and cut 3 10cm*10cm swatches from each layer, i.e. 3 sets of swatches. Take 1 swatch from each layer and stack them in the order of the layers in the sanitary product. Then wrap them with waterproof tape on all sides, 0.5cm away from the edges. Then, add 5ml of grade 3 water at a height of 1cm from the surface of the muscle layer (skin side). After absorbing the liquid for 30 seconds, place a piece of filter paper (weighed in advance and recorded as G1) on the wetted surface, place a 10cm*10cm acrylic plate on it, and then increase the pressure by 50g / cm 2 After the filter paper absorbs water, weigh the filter paper after absorbing the liquid and record it as G2. Calculate the weight of the water absorbed from the surface layer by the filter paper: G = G2 - G1. The ratio of this weight to the weight of 5 ml of water (5 g) added is the reverse osmosis rate, calculated as follows: Reverse osmosis rate (%) = [(G2 - G1) / 5] * 100%. Measure the reverse osmosis rates of the remaining two groups of fabric samples in the same manner, and take the average value as the reverse osmosis rate of the present invention.

[0075] (10) Water absorption of leak-proof parts

[0076] Disassemble the leak-proof component and cut three 6cm*27cm fabric swatches from each layer, i.e., three sets of swatches. Take one swatch from each layer and stack them according to the order of the layers in the sanitary product. Wrap the swatch with waterproof tape on all sides, 0.5cm from each edge, to serve as the test sample. Then, drip 5ml of Grade 3 water at a height of 1cm from the surface of the skin layer. After one minute, tilt the sample at a 45° angle to see if any liquid leaks. Repeat this process 5ml / time multiple times (stop if leakage occurs). Calculate the total amount of Grade 3 water dripped before leakage; this is the water absorption capacity of the leak-proof component.

[0077] (11) Comfort (self-report of actual wearing experience)

[0078] The comfort rating is based on actual wearing comfort. The number of test subjects is 10, and the comfort rating scale is 0 to 100. The average of the scores of the 10 people is taken as the wearing comfort score, and the rating is based on the score:

[0079] 1. Comfort (76-100 points): ○

[0080] 2. Relatively comfortable (51-75 points): △

[0081] 3. Uncomfortable (0-50 points): ×.

[0082] (12) Anti-side leakage effect (visual method)

[0083] Disassemble the leak-proofing component and cut a 6cm x 27cm fabric sample from each layer. Stack each layer according to the order in which the layers are in the sanitary product. Wrap the sample with waterproof tape on all sides, leaving a 0.5cm distance from each edge. Then, drip 10ml of grade 3 water (approximately two menstrual cycles) 1cm above the surface of the muscular layer. After one minute, tilt the sample at a 45° angle to observe any leakage. A score of ○ indicates no leakage from the side; a score of × indicates leakage from the side.

[0183] Table 3

[0184] According to Table 1, Table 2 and Table 3,

[0185] (1) It can be seen from Example 2 and Example 1 that, under the same conditions, the fabric with convex strips made of cotton fiber is slightly smaller than the fabric with convex strips made of PET fiber in terms of longitudinal and transverse water absorption diffusion length ratio, but the dryness is better than the latter (the former has a low surface and inner water retention rate) and the water retention capacity is also higher than the latter.

[0186] (2) It can be seen from Examples 1 and 3 that, under the same conditions, the fabric with cotton fibers on the non-convex stripe structure surface has a smaller longitudinal and transverse water absorption diffusion length ratio than the fabric with polyamide fibers on the non-convex stripe structure surface, and its dryness is slightly lower than that of the latter (the former has a slightly higher surface and interior water retention rate), but its water retention capacity is higher than that of the latter.

[0187] (3) It can be seen from Example 5 and Example 4 that, under the same conditions, the longitudinal and transverse water absorption diffusion length ratios of the fabric with a convex stripe structure surface h of 1100 μm are comparable to those of the fabric with a convex stripe structure surface h of 980 μm. The former is better in dryness than the latter (the former has a low surface and interior water retention rate) and has a greater water retention capacity than the latter.

[0188] (4) It can be seen from Example 7 and Example 6 that, under the same conditions, the ratio of the longitudinal and transverse water absorption diffusion lengths of the fabric with a ribbed structural surface h of 3100 μm is comparable to that of the fabric with a ribbed structural surface h of 2718 μm. The former is slightly less dry than the latter (the former has a slightly higher ratio of the surface and inner water retention rates), but the water retention capacity is greater than the latter.

[0189] (5) It can be seen from Examples 12 and 13 that under the same conditions, the fabric with h of 9890 μm on the ribbed surface has a lower water retention than the fabric with h of 10200 μm on the ribbed surface, but its longitudinal and transverse water absorption diffusion length ratio is slightly larger than that of the latter, and its dryness is better than that of the latter (the former has a lower surface-to-interior water retention ratio).

[0190] (6) It can be seen from Example 15 and Example 14 that, under the same conditions, the fabric with a ribbed structural surface b / a of 12.0 is comparable to the fabric with a ribbed structural surface b / a of 15.0 in terms of longitudinal and transverse water absorption diffusion length ratio. The former is slightly better in dryness than the latter (the former has a slightly lower ratio of surface and inner water retention), and its water retention capacity is also slightly greater than that of the latter.

[0191] (7) It can be seen from Example 20 and Example 21 that, under the same conditions, the ratio of the longitudinal and transverse water absorption diffusion lengths of the fabric with a 4000 μm ribbed structure surface is comparable to that of the fabric with a 5200 μm ribbed structure surface. The former is slightly better in dryness than the latter (the former has a slightly lower ratio of surface and interior water retention), and its water retention capacity is also slightly greater than that of the latter.

[0192] (8) It can be seen from Example 23 and Example 22 that, under the same conditions, the fabric with b of 120 μm is not as good as the fabric with b of 98 μm in terms of water retention and dryness, but the ratio of longitudinal and transverse water absorption diffusion length is much larger than that of the latter.

[0193] (9) It can be seen from Example 25 and Example 24 that, under the same conditions, the ratio of longitudinal and transverse water absorption diffusion lengths of the fabric with b / a of 1.6 is comparable to that of the fabric with b / a of 0.9. Although the water retention of the former is lower than that of the latter, its dryness is better than that of the latter (the ratio of the surface and inner water retention rate of the former is lower).

[0194] (10) It can be seen from Example 26 and Example 27 that under the same conditions, the fabric with b / a of 3.0 and the fabric with b / a of 3.5 have similar longitudinal and transverse water absorption diffusion length ratios and surface and inner water retention ratios, but the water retention capacity of the former is greater than that of the latter.

[0195] (11) It can be seen from Example 28 and Example 29 that, under the same conditions, the fabric with b of 4980 μm has a similar surface and interior water retention ratio to the fabric with b of 5200 μm. Although the water retention of the former is slightly lower than that of the latter, the longitudinal and transverse water absorption diffusion lengths are larger than those of the latter.

[0196] (12) It can be seen from Comparative Example 1 and Example 6 that, under the same conditions, the ratio of the longitudinal and transverse water absorption diffusion lengths of the fabric with h / (a+b) of 0.1 is only 1.0 compared with the fabric with h / (a+b) of 1.7, and the dryness is significantly lower than that of the latter (the former has a high surface and interior water retention rate), and the water retention capacity is also very low.

[0197] (13) It can be seen from Comparative Example 2 and Example 13 that, under the same conditions, the ratio of longitudinal and transverse water absorption diffusion lengths of the fabric with h / (a+b) of 10.0 is only 1.0 compared with the fabric with h / (a+b) of 6.4, and the dryness is significantly lower than that of the latter (the former has a high surface and interior water retention rate), and the water retention capacity is also lower than that of the latter.

[0198] (14) It can be seen from Example 33 and Example 32 that, under the same conditions, the water absorption capacity, comfort level and side leakage prevention effect of the physiological pants with a static contact angle of 98° for the muscle surface layer are comparable to those of the physiological pants with a static contact angle of 75° for the muscle surface layer. Although the water absorption speed of the former is slightly lower than that of the latter, the reverse osmosis rate is lower than that of the latter, that is, the anti-reverse osmosis property is better than the latter.

[0199] (15) It can be seen from Example 34 and Example 37 that under the same conditions, the weight of the muscle surface layer is 68g / m 2 The physiological pants and the muscle surface layer weigh 55g / m 2 Compared with the physiological pants, the water absorption, comfort and anti-side leakage effects of the two are comparable. The former absorbs water slightly faster than the latter, and has a lower reverse osmosis rate than the latter, that is, its anti-reverse osmosis property is better than the latter.

[0200] (16) It can be seen from Examples 33 and 38 that under the same conditions, the weight of the muscle surface layer is 125g / m 2 The physiological pants and the muscle surface layer weigh 158g / m 2 Compared with the physiological pants, the water absorption, comfort and anti-side leakage effects of the two are comparable. Although the water absorption speed of the former is slightly lower than that of the latter, the reverse osmosis rate is significantly lower than that of the latter, that is, the anti-reverse osmosis performance is significantly better than the latter.

[0201] (17) It can be seen from Example 39 and Example 40 that, under the same conditions, the reverse osmosis rate, water absorption speed, water absorption amount and anti-side leakage effect of the physiological pants with a waterproof layer elongation of 38% are comparable to those of the physiological pants with a waterproof layer elongation of 15%, but the former is more comfortable than the latter.

[0202] (18) It can be seen from Example 42 and Example 41 that, under the same conditions, the water absorption capacity and side leakage prevention effect of the physiological pants with the convex strip structure facing the waterproof layer are comparable to those of the physiological pants with the convex strip structure facing the muscle layer. Although the water absorption speed of the former is slightly lower than that of the latter, the reverse osmosis rate is lower than that of the latter, that is, the reverse osmosis prevention is better than the latter, and the comfort is also better than the latter.

[0203] (19) It can be seen from Comparative Example 3 and Example 43 that, under the same conditions, the water absorption speed of the sanitary pants using only non-woven fabric as the water absorption and diffusion layer is significantly lower than that of the sanitary pants using both knitted fabric and non-woven fabric as the water absorption and diffusion layer, and the reverse osmosis rate is high and the water absorption capacity is low. In addition, the comfort and anti-side leakage effects are also very poor.

[0204] (20) It can be seen from Comparative Example 4 and Example 32 that, under the same conditions, the sanitary pants with terry knitted fabric as the water absorption and diffusion layer and the sanitary pants with concave-convex knitted fabric as the water absorption and diffusion layer have similar water absorption rates, but the former has a high reverse osmosis rate and low water absorption capacity, and is also very poor in comfort and side leakage prevention.
