[0031] Example 2

[0032] This embodiment provides a home textile fabric with moisture absorption and perspiration wicking function. Three polyester-cotton plain weave home textile fabrics with different blending ratios (the warp and weft yarn components of the home textile fabrics are exactly the same) are selected to test their moisture conduction and perspiration wicking performance. The sample parameters are as follows:

[0033] Sample 1: The warp yarn is 50wt% cotton fiber; the weft yarn is 50wt% polyester fiber, the yarn fineness of the warp yarn is 12.3tex, the yarn fineness of the weft yarn is 14.8tex; the yarn twist of the warp yarn is 95 (twist·(10cm) -1 ), the yarn twist of the weft yarn is 85 (twist·(10cm) -1 ), the fabric density of the warp yarn is 420 (roots·(10cm) -1 ), the fabric density of the weft yarn is 150 (roots·(10cm) -1 ), the thickness of the home textile fabric is 0.36 mm, and the gram weight of the home textile fabric is 82 (g·m -2 ), the warp and weft compactness ratio is 2.6;

[0036] Instruments used: YG(B)141D digital fabric thickness meter (Wenzhou Dayong Textile Instrument Co., Ltd.), YG(B)511B fabric density microscope (Wenzhou Dayong Textile Instrument Co., Ltd.), fabric resistance automatic test system (self-made), FA2104 electronic balance (Shanghai Precision Instrument Co., Ltd.).

[0037] Test Method

[0038] Resistance test method: The drop method is used to evaluate the moisture conduction and perspiration wicking performance of each sample, and a self-made fabric resistance automatic test system is used. The instrument principle is as follows Figure 1 As shown;

[0039] The simulated sweat (abbreviated as sweat) containing 0.9% mass fraction of NaCl solution was accurately measured by an adjustable pipette, 0.2 mL was injected through the injection tube, and then the timing was started. After the sweat penetrated from probe 1 to probe 2 along the home textile fabric, the resistance between the probes dropped from the order of GΩ to MΩ, and a voltage signal appeared at the voltmeter at both ends of the 20MΩ fixed resistor connected in series with the probe. Since the position of probe 2 is fixed, it is only necessary to record the time from the dripping moment of sweat to the migration to probe 2, and the sweat diffusion rate can be indirectly obtained. As the sweat evaporates, the resistance between probes 1 and 2 gradually increases, and the voltage value between the voltmeters decreases. When it approaches 0V, it means that the sweat has evaporated completely.

[0040] With probe 1 as the center, a probe is arranged at intervals of 4 mm along the warp, weft, 30°, 45° and 60° (the angle is the angle with the warp direction of the sample). The probes are distributed as follows: Figure 2 Probes are set up in both the upper and lower directions along the specimen, and the moisture conduction and perspiration discharge performance of sweat along different directions of the specimen can be obtained by detecting the resistance change between the probes and probe 1.

[0041] Moisture absorption and quick drying test of textiles

[0042] Referring to GB / T21655.2-2019 "Evaluation of Moisture Absorption and Quick-drying of Textiles Part 2: Dynamic Moisture Transfer Method", the dynamic moisture management tester (MMTⅡ) of SILAI-ATLARS Co., Ltd. was used to test the diffusion rate of the surface and inner layers of the sample. Each sample was tested 5 times and the average value was taken.

[0043] Fabric moisture permeability test

[0044] Referring to GB / T12704.1-2009 “Test method for water vapor permeability of textile fabrics Part 1: Moisture absorption method”, the water vapor permeability of each sample was tested using the YG216G fabric water vapor permeability meter produced by Shanghai Jifa Instrument Equipment Co., Ltd. Each sample was tested 5 times and the average value was taken.

[0045] Analysis of the differences in moisture conduction properties of various fabrics

[0046] When there is liquid water between the probes inserted into the fabric, the resistance value between the probes is in the order of MΩ. When there is no liquid water or the liquid water is not completely distributed between the probes, the resistance value between the probes is in the order of GΩ. The resistance value between each probe and the central probe 1 on the probe plate is marked to obtain the sweat diffusion situation. Record all probes with resistance values ​​of the order of MΩ in the warp, weft, 30°, 45° and 60° directions of the sample, select the probe farthest from the drop of sweat, and use the probe position as the front position of sweat diffusion. The statistical results of sweat diffusion along the sample are shown in the following table. At the same time, in order to quantitatively evaluate the diffusion differences of the sample in different directions, the directional deviation parameter index is introduced. Its value is based on the direction with the largest number of angles at a certain position point as the standard position point. If the front position points of sweat diffusion along the sample in all directions are the same, the directional deviation value is 1. If the front position of sweat along a certain direction is lower or higher than the standard position point, add 0.5. For example, if the standard position point of sample 1 is located at 12 mm in the middle, there are 2 directions below the standard position point and 1 direction above the standard position point. The directional deviation of sample 1 is 2.5.

[0047]

[0048] As shown in Table 1, for Sample 1 and Sample 3, the difference in the diffusion of sweat in all directions is large. When sweat diffuses, part of the water diffuses along the capillary pores inside the yarn, and part of the water diffuses between the yarns. Therefore, the difference in the thickness of the warp and weft yarns and the warp and weft density of the fabric will significantly affect the difference in the moisture conductivity of the fabric. Comparing the warp and weft tightness ratio with the deviation of the anisotropic moisture conductivity of the fabric, as the warp and weft tightness ratio of the fabric increases, the deviation of the anisotropic moisture conductivity of the fabric also increases. Therefore, when the warp and weft yarn materials of the fabric are the same, the difference in the warp and weft tightness will significantly affect the anisotropic moisture conductivity of the fabric.

[0049] Depend on Figure 3 As shown in the figure, when the cotton fiber content is between 35% and 50%, the sweat diffusion time does not change much overall. When the cotton fiber content is above 60%, the sweat diffusion time increases. The moisture management tester (MMT) evaluates the moisture conductivity of fabrics mainly by testing the diffusion rate of the surface layer and the inner layer of the sample. In order to facilitate comparison with the resistance method, the diffusion rate of the surface layer and the inner layer measured by the MMT instrument is averaged, and the maximum time required for sweat to diffuse to 8mm is divided by the time required for sweat to diffuse to 8mm to obtain the moisture conductivity rate of the resistance method. The two are compared. Figure 4 As shown, Figure 4 The fabric moisture conduction rate measured by the medium resistance method and the MMT instrument is close in magnitude, but there is a certain difference between the two values, mainly due to the difference in the test and evaluation methods. The linear fitting of the two values ​​shows a correlation of 0.9367, indicating that both methods can clearly distinguish the quality of fabric moisture conduction performance. Therefore, the test results of the homemade tester are stable and reliable, which can meet the test and analysis of fabric moisture conduction performance.

[0050] Depend on Figure 1 From the probe distribution diagram, it can be seen that when the water at the nearest probe (4mm position) around the injection tube evaporates, very little water remains in the fabric. The water evaporation time at these probe positions can be used as an evaluation benchmark. The larger the value, the slower the sweat in the fabric dries. The sweat evaporation time in the fabric is characterized by the drying time, and the relationship between the sweat drying time and the cotton fiber content in the blended fabric is analyzed, such as Figure 5 As shown, the maximum value and average value have the same meaning as Figure 3 The meanings expressed in have the same meaning.

[0051] Depend on Figure 5 From the trend distribution of each data point, it can be seen that as the cotton fiber content in polyester-cotton blended fabrics increases, the drying time of sweat on the fabric becomes longer and the evaporation rate decreases.

[0052] The moisture permeability is selected to evaluate the comfort of blended fabrics. The relationship between the moisture permeability of fabrics and the cotton fiber content in blended fabrics is as follows: Figure 6 shown.

[0053] Depend on Figure 6 It can be seen that as the cotton fiber content increases, the moisture permeability of the sample gradually increases. When the cotton fiber content exceeds 50%, the moisture permeability of the sample is significantly improved. The main reason may be that the surface of the cotton fiber is naturally curved, which is easy to form abundant pores; at the same time, the internal pores of the cotton fiber are more than those of polyester. When the cotton fiber content is high, it is conducive to the permeation of water through the sample. When the cotton fiber content is less than 50%, the sweat diffusion time and drying time are relatively small, indicating that the sample has excellent moisture conduction and perspiration performance. Combined with the comprehensive analysis of moisture permeability and moisture conduction and perspiration performance, the product has the best comprehensive performance when the polyester / cotton blending ratio is 50 / 50.

[0054] Effect of structural parameters on fabric moisture conduction and perspiration wicking performance

[0055] The main factors affecting the moisture conduction and perspiration management of fabrics include fiber composition, blending ratio, yarn fineness, twist, fabric structure and thickness.

[0056] In samples 1-3, the degree of yarn twisting is not much different; the warp and weft yarn thickness and warp and weft density parameters can be combined into the fabric tightness parameters. The influence of structural parameters on fabric moisture conduction and perspiration wicking performance only needs to consider the cotton fiber content, fabric thickness and tightness in the fabric, and multiply the three to obtain the fabric structural parameter value. Diffusion time and drying time are used as fabric moisture conduction and drying performance parameters. The relationship between the two and fabric structural parameters is as follows: Figure 7 and 8 shown.

[0057] Figure 7 and Figure 8The fabric structural parameters in the test significantly affect the sweat diffusion time and drying time. Linear fitting was performed between them and the fabric structural parameters, and the correlations were 0.9089 and 0.9124, respectively. This shows that the cotton fiber content, fabric tightness and thickness can significantly affect the moisture conduction and perspiration wicking properties of the fabric. That is, the more cotton fiber content, the tighter the fabric and the thicker the fabric, the worse the sweat conduction and evaporation performance of the fabric.

[0058] Example 3

[0059] The present embodiment provides a home textile fabric with moisture absorption and perspiration wicking function. The home textile fabric sample 1 obtained in Example 2 is dyed and moisture absorption and quick-drying finished. The specific dyeing operation is: high temperature overflow dyeing, dyeing temperature is 98°C, and heat preservation time is 45min; the dye selection ratio is: dispersed navy blue PTN: 2%; dispersed yellow brown XF: 0.6%; dispersed red HFW-4B: 0.3%; glacial acetic acid: 0.5g·L -1 ; The bath ratio is 1:6, and the specific operation steps of the moisture absorption and quick-drying finishing are: a two-step method of dipping-padding: dipping HipomSR-256 moisture absorption and quick-drying agent in an overflow cylinder, followed by dehydration, and then using a shaping machine to pad HipomHP-195-2 polyurethane moisture absorption and perspiration processing agent (liquid rolling rate 75%), and finally finishing and shaping the material. In the moisture absorption and quick-drying finishing, the mass fraction of HipomSR-256 moisture absorption and quick-drying agent is 0.5% to 3% (omf), such as (0.5% omf, 1.0% omf, 1.5% omf, 2.0% omf, 2.5% omf, 3.0% omf), the dipping temperature is 60 to 100°C, such as (60°C, 70°C, 80°C, 90°C, 100°C), Hip The mass concentration of omHP-195-2 polyurethane moisture absorption and perspiration processing agent is 5-30g / L, such as (5g / L, 10g / L, 15g / L, 20g / L, 25g / L, 30g / L), and the setting temperature is 130-180℃, such as (130℃, 140℃, 150℃, 160℃, 170℃, 180℃). The dispersed navy blue PTN, dispersed yellow brown XF, and dispersed red HFW-4B are all selected from Jiangsu Dewang Chemical Co., Ltd. The HipomSR-256 moisture absorption and quick-drying agent is also known as polyester polyether block moisture absorption and quick-drying auxiliary agent. The HipomSR-256 moisture absorption and quick-drying agent and HipomHP-195-2 polyurethane moisture absorption and perspiration processing agent are both selected from Suzhou Weimin Chemical Industry Co., Ltd.

[0060] This example analyzes the amount of Hipom SR-256 moisture absorption and quick drying agent, the immersion temperature, the amount of Hipom HP-195-2 polyurethane moisture absorption and perspiration processing agent, and the setting temperature.

[0061] The anti-pilling performance test is based on GB / T4802.2-2008 "Martindale method for pilling test of textile fabrics". After rubbing 2000 times, the anti-pilling performance of the fabric before and after finishing is tested, and the tested fabric is photographed using a three-dimensional video microscope.

[0062] The test of moisture absorption and perspiration absorbing agent fixation rate is based on GB / T8629-2017 "Household washing and drying procedures for textile testing". After washing and drying for 30 times, the weight difference of the undyed and finished fabric before and after washing is tested to characterize the residual rate of moisture absorption and perspiration absorbing agent. The higher the residual rate, the better the washing resistance of the additive.

[0063] The moisture absorption and quick-drying performance test is based on GB / T21655.1-2023 "Evaluation of Moisture Absorption and Quick-drying of Textiles Part 1: Single Combination Test Method". The moisture absorption and quick-drying performance indicators of the fabric are tested before washing and after washing and drying 30 times. The washing method is based on GB / T8629-2017.

[0064] The color fastness to washing with soap test is based on GB / T3921-2008 "Textiles - Tests for Color Fastness - Color Fastness to Washing", and the color fastness to washing with soap of fabrics with different finishing processes is tested respectively.

[0065] 1. Dosage of HipomSR-256 moisture absorbing and quick drying agent

[0066] The immersion temperature was fixed at 80℃ for 20min, HipomHP-195-2 polyurethane moisture absorption and perspiration processing agent was 20g / L, and the setting temperature was 150℃. The effect of the dosage of HipomSR-256 moisture absorption and quick drying agent on the drying rate and color fastness to soap washing was studied. The results are shown in Table 2.

[0067] Table 2: Effect of the dosage of HipomSR-256 moisture absorbing and quick drying agent

[0068] Mass fraction / %(omf) 0.5 1.0 1.5 2.0 2.5 3.0 <![CDATA[Drying rate ( / g·h -1 )]]> 0.14 0.20 0.28 0.37 0.38 0.40 Color fastness to soap washing / grade 4 4 4 4 4 3～4

[0069] It can be seen from Table 2 that when the mass fraction of HipomSR-256 hygroscopic fast-drying agent is 2.0% (omf), the drying rate has reached 0.38g / h, and further increasing the dosage has little effect on the drying rate improvement effect.

[0070] 2. Soaking temperature

[0071] The mass fraction of HipomSR-256 moisture absorption and quick drying agent was fixed at 2.0% (omf), HipomHP-195-2 polyurethane moisture absorption and perspiration processing agent was 20g / L, and the setting temperature was 150°C. The effect of immersion temperature on drying rate and color fastness to soaping was studied. The results are shown in Table 3.

[0072] Table 3: Effect of immersion temperature

[0073] Dipping temperature / ℃ 60 70 80 90 100 <![CDATA[Drying rate ( / g·h -1 )]]> 0.24 0.31 0.38 0.43 0.48 Color fastness to soap washing / grade 4 4 4 3～4 3

[0074] It can be seen from Table 3 that with the increase of immersion temperature, the drying rate gradually increases, but when the temperature exceeds 80°C, the color fastness to soap washing decreases rapidly.

[0075] 3. Dosage of HipomHP-195-2 polyurethane moisture absorption and perspiration processing agent

[0076] The mass fraction of HipomSR-256 moisture absorption and quick-drying agent was fixed at 2.0% (omf), immersed at 80℃ for 20min, and the setting temperature was 150℃. The effect of the amount of HipomHP-195-2 polyurethane moisture absorption and perspiration processing agent on the drying rate and color fastness to soap washing was studied. The results are shown in Table 4.

[0077] Table 4: Effect of the dosage of HipomHP-195-2 polyurethane absorption and discharge processing agent

[0078]

[0079]

[0080] It can be seen from Table 4 that with the increase in the amount of HipomHP-195-2 hygroscopic polyurethane moisture wicking agent, the drying rate gradually increases, but after the mass concentration exceeds 20g / L, the drying rate tends to balance.

[0081] 4. Setting temperature

[0082] The mass fraction of HipomSR-256 moisture absorption and quick drying agent was fixed at 2.0% (omf), immersed at 80℃ for 20min, and HipomHP-195-2 polyurethane moisture absorption and perspiration processing agent was 20g / L. The effect of setting temperature on drying rate and color fastness to soap washing was studied. The results are shown in Table 5.

[0083] Table 5: Effect of setting temperature

[0084] It can be seen from Table 5 that when the setting temperature reaches 150°C, the drying rate reaches the maximum value; when the temperature exceeds 150°C, the color fastness decreases significantly.

[0085] 5. Anti-pilling performance test

[0086] After the two-step impregnation-pad finishing, the anti-pilling performance of the fabric is improved to level 4-5. The reason is that the polyurethane moisture absorption and perspiration aid forms a film on the fiber surface, which reduces the directional friction effect between fibers and weakens the slippage between fibers, so it is not easy to pilling when rubbed.

[0087] 6. The test results of fabric moisture absorption and quick-drying performance are shown in Table 6.

[0088]

[0089] It shows that by using polyester polyether block and water-based polyurethane moisture wicking finishing agents together, while maintaining the excellent moisture absorption and quick-drying function and color fastness of Miolio moisture wicking additive, its wash resistance is further improved through the use of polyester polyether block additives.

[0090] In summary, polyester polyether moisture absorption and perspiration aids are first used to cross-link polyester fibers, and then polyurethane moisture absorption and perspiration aids are used to form a film on polyester fibers through polyether blocks. This can give home textile fabrics excellent moisture absorption and quick-drying properties and washability, improve the fabric's anti-pilling properties, and does not affect color fastness.

[0091] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
