Description
技术领域Technical Field
本发明属于纺织技术领域，具体涉及一种单向导湿保暖织物及其制备方法与应用。The invention belongs to the field of textile technology, and in particular relates to a unidirectional moisture-conducting and warm-keeping fabric and a preparation method and application thereof.
背景技术Background technique
长期处于低温环境会使人体产生不适感，严重的甚至会造成死亡。在室内环境中空调、电热扇、地暖等成为了目前常用的室内采暖方式，但高能耗给能源供应和环境保护带来了巨大的压力；此外室外环境也是人们生活不可缺少的场景。为了实现人体的热舒适性，降低取暖能耗，基于人体与环境微环境热管理的个人热管理(Personal ThermalManagement(PTM))正成为一种有效的解决方案。Being in a low temperature environment for a long time can cause discomfort to the human body, and in severe cases, it can even cause death. In indoor environments, air conditioning, electric fans, floor heating, etc. have become common indoor heating methods, but high energy consumption has brought huge pressure to energy supply and environmental protection; in addition, the outdoor environment is also an indispensable scene in people's lives. In order to achieve thermal comfort for the human body and reduce heating energy consumption, Personal Thermal Management (PTM) based on thermal management of the human body and environmental microenvironment is becoming an effective solution.
目前，解决保温问题的产品大多采用太阳能取暖材料、相变材料、化学能源取暖材料、电加热材料等来储热或发热。然而，这些常用产品存在一定的局限性，如外观僵硬、发热不稳定、操作条件要求苛刻、存在安全隐患等。人体的散热途径主要有热对流、热传导、热辐射，其中热辐射在人体散热中起着不可或缺的作用，在办公室等典型的室内场景中，热辐射占总散热的50％以上。新型的个人热管理纺织品通过减少人体热辐射而获得保温效果。At present, most products that solve the insulation problem use solar heating materials, phase change materials, chemical energy heating materials, electric heating materials, etc. to store or generate heat. However, these commonly used products have certain limitations, such as rigid appearance, unstable heating, demanding operating conditions, and potential safety hazards. The main ways of heat dissipation in the human body are heat convection, heat conduction, and heat radiation. Among them, heat radiation plays an indispensable role in human body heat dissipation. In typical indoor scenes such as offices, heat radiation accounts for more than 50% of the total heat dissipation. New personal thermal management textiles achieve insulation effects by reducing human body heat radiation.
现有的PTM织物虽然提升了保暖性能，但忽视了人体水分管理。若汗水不能及时排出体外则会造成湿热感，影响穿着舒适性；此外，残留在织物上的水分在蒸发时也需要吸收热量。Although existing PTM fabrics have improved thermal insulation performance, they ignore the management of human moisture. If sweat cannot be discharged from the body in time, it will cause a sense of dampness and heat, affecting wearing comfort; in addition, the moisture remaining on the fabric also needs to absorb heat when evaporating.
发明内容Summary of the invention
本发明所要解决的第一个技术问题是：The first technical problem to be solved by the present invention is:
提供一种单向导湿保暖织物。所述单向导湿保暖织物为双层疏水差异性结构，该结构使得单向导湿保暖织物减少了汗液在织物上的残留，进而降低了汗液蒸发时所需的热量以及出汗后织物的凉感系数。Provided is a unidirectional moisture-conducting thermal insulation fabric having a double-layer hydrophobic differential structure, which reduces the residual sweat on the fabric, thereby reducing the heat required for sweat evaporation and the coolness coefficient of the fabric after sweating.
本发明所要解决的第二个技术问题是：The second technical problem to be solved by the present invention is:
提供一种所述单向导湿保暖织物的制备方法。A method for preparing the one-way moisture-conducting and warm-keeping fabric is provided.
本发明所要解决的第三个技术问题是：The third technical problem to be solved by the present invention is:
所述单向导湿保暖织物的应用。Application of the one-way moisture-conducting and warm-keeping fabric.
为了解决所述第一个技术问题，本发明采用的技术方案为：In order to solve the first technical problem, the technical solution adopted by the present invention is:
一种单向导湿保暖织物，包括基体层，所述基体层一侧设有疏水层；A unidirectional moisture-conducting thermal insulation fabric comprises a base layer, and a hydrophobic layer is provided on one side of the base layer;
所述疏水层包括以下重量份的组分：The hydrophobic layer comprises the following components in parts by weight:
1-3份的防水剂、1-5份的二氧化硅、1-5份的增稠剂和0-6份的氧化石墨烯。1-3 parts of water-proofing agent, 1-5 parts of silicon dioxide, 1-5 parts of thickener and 0-6 parts of graphene oxide.
仅在一侧设置疏水层，使得所述单向导湿保暖织物基体两侧形成疏水差异性结构，该结构使得单向导湿保暖织物减少了汗液在织物上的残留，进而降低了汗液蒸发时所需的热量以及出汗后织物的凉感系数。A hydrophobic layer is set only on one side, so that a hydrophobic difference structure is formed on both sides of the one-way moisture-conducting thermal insulation fabric substrate. This structure reduces the residue of sweat on the one-way moisture-conducting thermal insulation fabric, thereby reducing the heat required for sweat evaporation and the coolness coefficient of the fabric after sweating.
所述单向导湿保暖织物不仅可进行被动式保暖还可以快速的排出人体汗液并防止外界液体的侵入，即同时进行热/湿管理。The one-way moisture-conducting thermal insulation fabric can not only perform passive thermal insulation but also quickly discharge human sweat and prevent the intrusion of external liquids, that is, perform heat/moisture management at the same time.
当所述单向导湿保暖织物的涂层面(接近人体皮肤的里层)中不包含氧化石墨烯时，由于涂层面疏水性大于远离人体皮肤的非涂层面，这使得人体的汗液更容易排到外层，使得汗液不会积累在里层，保持人体干爽。此外，即使当所述单向导湿保暖织物的涂层面不包含氧化石墨烯时，该织物也具有较好的保暖性。When the coating surface of the unidirectional moisture-conducting thermal insulation fabric (the inner layer close to human skin) does not contain graphene oxide, since the hydrophobicity of the coating surface is greater than that of the non-coating surface away from human skin, it makes it easier for human sweat to be discharged to the outer layer, so that sweat will not accumulate in the inner layer, keeping the human body dry. In addition, even when the coating surface of the unidirectional moisture-conducting thermal insulation fabric does not contain graphene oxide, the fabric has good warmth retention.
进一步地，所述单向导湿保暖织物为双层疏水差异性结构，其中，当所述单向导湿保暖织物的涂层一面中含有氧化石墨烯时，氧化石墨烯能够增强所述单向导湿保暖织物反射红外线的效果，从而使得所述单向导湿保暖织物能够反射人体皮肤发射出来的红外线，增强了所述单向导湿保暖织物的保暖性。Furthermore, the one-way moisture-conducting thermal insulation fabric has a double-layer hydrophobic differential structure, wherein, when one side of the coating of the one-way moisture-conducting thermal insulation fabric contains graphene oxide, the graphene oxide can enhance the effect of the one-way moisture-conducting thermal insulation fabric in reflecting infrared rays, thereby enabling the one-way moisture-conducting thermal insulation fabric to reflect infrared rays emitted by human skin, thereby enhancing the warmth retention of the one-way moisture-conducting thermal insulation fabric.
所述单向导湿保暖织物提供了一种同时调节织物热/湿舒适性的织物，确保织物有效保暖情况下保持人体干爽。The one-way moisture-conducting thermal fabric provides a fabric that simultaneously adjusts the thermal/moisture comfort of the fabric, ensuring that the fabric effectively keeps the human body dry.
根据本发明的一种实施方式，所述基体层包括涤纶织物。According to one embodiment of the present invention, the base layer comprises polyester fabric.
根据本发明的一种实施方式，所述涤纶织物的经密为0-300根/10cm，纬密为0-160根/10cm，细度为0-55tex，优选的，所述涤纶织物的经密为120-300根/10cm，纬密为112-230根/10cm。According to one embodiment of the present invention, the warp density of the polyester fabric is 0-300 strands/10cm, the weft density is 0-160 strands/10cm, and the fineness is 0-55tex. Preferably, the warp density of the polyester fabric is 120-300 strands/10cm, and the weft density is 112-230 strands/10cm.
根据本发明的一种实施方式，所述防水剂包括聚丙烯酸型无氟防水剂、聚氨酯类疏水剂和有机硅类防水剂中的至少一种。According to one embodiment of the present invention, the waterproofing agent includes at least one of a polyacrylic acid type fluorine-free waterproofing agent, a polyurethane type hydrophobic agent and a silicone type waterproofing agent.
无氟防水剂可降低织物表面能，从而增强了织物的疏水性。Fluorine-free water repellent can reduce the surface energy of fabrics, thereby enhancing the hydrophobicity of fabrics.
根据本发明的一种实施方式，所述增稠剂包括聚丙烯酸酯、聚氨酯和聚丙烯酰胺中的至少一种。According to one embodiment of the present invention, the thickener includes at least one of polyacrylate, polyurethane and polyacrylamide.
所述单向导湿保暖织物中的增稠剂起到增强浆料粘度作用，在进行单面涂层整理时，防止浆料渗透到织物背面。The thickener in the one-way moisture-conducting thermal insulation fabric plays a role in enhancing the viscosity of the slurry, and prevents the slurry from penetrating to the back side of the fabric when performing single-side coating finishing.
根据本发明的一种实施方式，所述二氧化硅为疏水型纳米二氧化硅，粒径为10-15nm，比表面积为300±50m2/g。According to one embodiment of the present invention, the silicon dioxide is hydrophobic nano-silicon dioxide with a particle size of 10-15 nm and a specific surface area of 300±50 m 2 /g.
所述单向导湿保暖织物中的纳米二氧化硅起到增强表面粗糙度、制造微纳米结构的作用。粗糙度的增加可进一步增强涂层侧的疏水性，从而增加与非涂层侧疏水性的差别。双侧较大的疏水性有利于提升单向导湿性能。The nano-silicon dioxide in the unidirectional moisture-conducting thermal insulation fabric plays a role in enhancing the surface roughness and manufacturing micro-nano structures. The increase in roughness can further enhance the hydrophobicity of the coating side, thereby increasing the difference in hydrophobicity with the non-coating side. The greater hydrophobicity on both sides is conducive to improving the unidirectional moisture-conducting performance.

氧化石墨烯中具有含氧官能团，使得其具有亲水性，因此控制好氧化石墨烯用量，使得本发明浆料整体呈现出涂层面与非涂层面较大的疏水差异性，这有利于实现织物的单向导湿功能。氧化石墨烯表面的亲水性含氧活性基团使其具有很强的表面活性，从而使氧化石墨烯能够在极性溶液中良好的分散。本发明使用水性防水剂，使得氧化石墨烯可以很好的分散在其中。Graphene oxide has oxygen-containing functional groups, which makes it hydrophilic. Therefore, the amount of graphene oxide is controlled so that the slurry of the present invention as a whole presents a large hydrophobic difference between the coating surface and the non-coating surface, which is conducive to achieving the unidirectional moisture conduction function of the fabric. The hydrophilic oxygen-containing active groups on the surface of graphene oxide make it have strong surface activity, so that graphene oxide can be well dispersed in polar solutions. The present invention uses a water-based waterproofing agent so that graphene oxide can be well dispersed therein.
所述单向导湿保暖织物中的氧化石墨烯可以将人体的红外进行反射，使得热量很好的被保留在织物里侧(涂层面)，从而防止了热量的损失。The graphene oxide in the unidirectional moisture-conducting thermal insulation fabric can reflect infrared radiation from the human body, so that the heat is well retained on the inner side of the fabric (coating surface), thereby preventing heat loss.

对比例1Comparative Example 1
本对比例提供了一种织物，与实施例6不同之处在于底物变为碱减量涤纶(碱减率为10％)。碱减量涤纶制备方法如下：This comparative example provides a fabric, which is different from Example 6 in that the substrate is changed to alkali-reduced polyester (alkali reduction rate is 10%). The preparation method of alkali-reduced polyester is as follows:
1)涤纶织物称重。1) Weighing of polyester fabric.
2)称取碳酸钠4g，连二亚硫酸钠0.5g，溶解与1000mL去离子水中，配置成预处理液。然后将称重好的涤纶织物放入溶液中，在90℃水浴条件下预处理20分钟，水洗，以去除涤纶织物表面的灰尘、油脂以及其他杂质。2) Weigh 4g of sodium carbonate and 0.5g of sodium dithionite, dissolve them in 1000mL of deionized water to prepare a pretreatment solution. Then put the weighed polyester fabric into the solution, pretreat it in a 90℃ water bath for 20 minutes, and wash it with water to remove dust, grease and other impurities on the surface of the polyester fabric.
3)称取氢氧化钠4g，苯扎氯铵2g搅拌均匀，将经过预处理的涤纶织物分别放入碱处理液中，在99℃恒温水浴锅中处理60分钟，水洗，60℃烘干，得到碱减量涤纶。3) Weigh 4 g of sodium hydroxide and 2 g of benzalkonium chloride and stir them evenly. Put the pretreated polyester fabrics into the alkali treatment solution respectively, treat them in a constant temperature water bath at 99° C. for 60 minutes, wash with water, and dry at 60° C. to obtain alkali-reduced polyester.
其中碱减率计算方法为：The calculation method of alkali reduction rate is:
其中，g1是未处理织物质量，g2是处理后织物质量，g1为170.6g，g2为152.3g。Wherein, g1 is the mass of untreated fabric, g2 is the mass of treated fabric, g1 is 170.6 g, and g2 is 152.3 g.
对比例2Comparative Example 2
本对比例提供了一种织物，本对比例与实施例6的不同之处在于，底物替换为棉织物。This comparative example provides a fabric. The difference between this comparative example and Example 6 is that the substrate is replaced by cotton fabric.
性能测试：Performance Testing:
1.对实施例1-6的单向导湿保暖织物的水接触角进行测试，测试结果如表1。1. The water contact angles of the unidirectional moisture-conducting thermal insulation fabrics of Examples 1-6 were tested. The test results are shown in Table 1.
表1织物双侧接触角数据表Table 1 Fabric double-sided contact angle data table
从表1可以看出，在实施例1-3中随着无氟防水剂用量的增加，涂层侧的接触角增大，这是因为无氟防水剂可降低织物表面能，从而增强了疏水性；在实施例4-6中，随着氧化石墨烯用量的增加，涂层侧接触角逐渐减小，这是因为氧化石墨烯中具有含氧官能团增强了浆料的亲水性，进而使得涂层侧疏水性减弱，但织物的涂层侧与非涂层侧的接触角仍保持较大的差异性，这有利于实现织物的单向导湿功能。It can be seen from Table 1 that in Examples 1-3, as the amount of fluorine-free waterproofing agent increases, the contact angle on the coating side increases. This is because the fluorine-free waterproofing agent can reduce the surface energy of the fabric, thereby enhancing the hydrophobicity; in Examples 4-6, as the amount of graphene oxide increases, the contact angle on the coating side gradually decreases. This is because the oxygen-containing functional groups in graphene oxide enhance the hydrophilicity of the slurry, thereby weakening the hydrophobicity of the coating side. However, the contact angles of the coating side and the non-coating side of the fabric still maintain a large difference, which is conducive to achieving the unidirectional moisture conduction function of the fabric.
水接触角的测量方法：Water contact angle measurement method:
使用德国Kruss公司DSA25E接触角测量仪，分别将5μL去离子水滴在织物上，随机测量五个位点，取其平均值。Using the DSA25E contact angle meter from Kruss, Germany, 5 μL of deionized water was dropped on the fabric, five random locations were measured, and the average value was taken.
2.对实施例2、实施例4、实施例5和实施例6的单向导湿保暖织物的涂层侧接触角变为零所需的时间进行测试，结果如表2。2. The time required for the contact angle of the coating side of the unidirectional moisture-conducting thermal insulation fabrics of Examples 2, 4, 5 and 6 to become zero was tested. The results are shown in Table 2.
表2涂层侧接触角变为零所需的时间Table 2 Time required for the contact angle of the coating side to become zero
从表2可以看出，随着织物涂层侧接触角的减小，水滴在涂层侧接触角变为0的时间逐渐加快，这是由于涂层侧对水滴的排斥力逐渐减弱，更有利于水滴顺利的穿透涂层侧到达非涂层侧。结果表明实施例6具有更好的单向导湿效果。As can be seen from Table 2, as the contact angle of the fabric coating side decreases, the time for the water droplet contact angle on the coating side to become 0 gradually accelerates. This is because the repulsive force of the coating side on the water droplet gradually weakens, which is more conducive to the water droplet to smoothly penetrate the coating side to reach the non-coating side. The results show that Example 6 has a better unidirectional moisture conduction effect.
样品单向导湿能力测量方法：Method for measuring the unidirectional moisture conduction capacity of samples:
使用德国Kruss公司DSA25E接触角测量仪，分别将5μL去离子水滴在织物的涂层面上，观察接触角变为0的时间。Using the DSA25E contact angle measuring instrument from Kruss Company of Germany, 5 μL of deionized water was dropped on the coating surface of the fabric and the time when the contact angle became 0 was observed.
3.对实施例2、实施例4、实施例5和实施例6的单向导湿保暖织物的非涂层面温度进行测试，结果如图2和表3。3. The non-coating surface temperature of the unidirectional moisture-conducting thermal insulation fabrics of Examples 2, 4, 5 and 6 was tested. The results are shown in FIG2 and Table 3.
图2为实施例2、实施例4、实施例5和实施例6中不同含量氧化石墨烯浆料制备的单向导湿保暖织物非涂层面温度变化测试图。其中，图2中的(a)-(d)图对应于氧化石墨烯含量依次为0.0重量份，3.0重量份，4.5重量份，6.0重量份时织物非涂层面的初始温度。图2中的(a1)-(d1)图对应于氧化石墨烯含量为0.0重量份，3.0重量份，4.5重量份，6.0重量份时单向导湿保暖织物的非涂层面加热后的温度。FIG2 is a test diagram of the temperature change of the non-coated surface of the unidirectional moisture-conducting thermal insulation fabric prepared with different contents of graphene oxide slurry in Example 2, Example 4, Example 5 and Example 6. Among them, (a)-(d) in FIG2 correspond to the initial temperature of the non-coated surface of the fabric when the content of graphene oxide is 0.0 weight part, 3.0 weight part, 4.5 weight part and 6.0 weight part respectively. ( a1 )-( d1 ) in FIG2 correspond to the temperature of the non-coated surface of the unidirectional moisture-conducting thermal insulation fabric after heating when the content of graphene oxide is 0.0 weight part, 3.0 weight part, 4.5 weight part and 6.0 weight part.
表3非涂层面温度随氧化石墨烯用量变化表Table 3 Non-coating surface temperature changes with graphene oxide dosage
由图2和表3可以看出，由于织物本身的隔热性能，非涂层面的温度均低于加热板所设置的55℃。在初始温度、加热温度相同的情况下，添加氧化石墨烯的样品非涂层侧温度均低于未添加的样品，且随着氧化石墨烯用量的增加非涂层侧温度逐渐降低。这是因为氧化石墨烯可以将人体的红外进行反射，从而防止了热量的损失。实施例6织物表面温度比加热板降低了6.9℃，表明热量很好的被保留在织物里侧(涂层面)。As can be seen from Figure 2 and Table 3, due to the thermal insulation performance of the fabric itself, the temperature of the non-coated surface is lower than the 55°C set by the heating plate. When the initial temperature and heating temperature are the same, the temperature of the non-coated side of the sample with added graphene oxide is lower than that of the sample without addition, and the temperature of the non-coated side gradually decreases with the increase of the amount of graphene oxide. This is because graphene oxide can reflect the infrared of the human body, thereby preventing heat loss. The surface temperature of the fabric in Example 6 is 6.9°C lower than that of the heating plate, indicating that the heat is well retained on the inner side of the fabric (coated surface).
保暖性能测量方法：Thermal insulation performance measurement method:
使用日本NEC-Avio公司R550-Pro红外热成像测温系统，将3cm×3cm大小的实施例2、实施例4、实施例5和实施例6制备的单向导湿织物放在加热台上(非涂层面朝上，加热台温度设定最高温度为55℃)，利用红外热成像相机可测量出非涂层面温度。Using the R550-Pro infrared thermal imaging temperature measurement system of Japan's NEC-Avio Company, the 3 cm × 3 cm one-way moisture-conducting fabrics prepared in Example 2, Example 4, Example 5 and Example 6 were placed on a heating table (the non-coated surface faced upward, and the heating table temperature was set to a maximum temperature of 55°C), and the non-coated surface temperature was measured using an infrared thermal imaging camera.
4.对实施例6制备的单向导湿保暖织物和对比例1、对比例2制备的织物的水分残留量及接触凉感系数(Qmax)进行测试，测试结果如表4。4. The residual moisture content and contact coolness coefficient (Q max ) of the unidirectional moisture-conducting warm fabric prepared in Example 6 and the fabrics prepared in Comparative Examples 1 and 2 were tested. The test results are shown in Table 4.
表4织物的水分残留量及接触凉感系数(Qmax)Table 4 Residual moisture content and contact coolness coefficient (Q max ) of fabrics
由表4可以看出，在水分传输过程中实施例6的水分损耗量比对比例1、对比例2小了一个数量级。从而使得在润湿状态下具有更小的接触凉感系数，降低了人体因出汗而产生了寒冷感。尤其是是在润湿状态(模拟人体出汗)下凉感系数降低明显。It can be seen from Table 4 that the water loss of Example 6 during the water transmission process is one order of magnitude smaller than that of Comparative Examples 1 and 2. As a result, the contact coolness coefficient is smaller in the wet state, reducing the coldness caused by sweating of the human body. In particular, the coolness coefficient is significantly reduced in the wet state (simulating human sweating).
结果表明单侧涂覆保暖疏水浆料的涤纶织物可以有效的使织物同时具备热/湿舒适性的管理功能。即实施例6制备的单向导湿织物效果最优。The results show that the polyester fabric coated with the thermal hydrophobic slurry on one side can effectively make the fabric have the management function of heat/moisture comfort at the same time. That is, the unilateral moisture-conducting fabric prepared in Example 6 has the best effect.
对比例1和对比例2中分别使用了碱处理涤纶与棉织物为基材，结果证明由于基材变为了亲水性产品，使得织物在润湿状态下接触凉感系数(Qmax)变大，破坏了保暖性能。Comparative Examples 1 and 2 used alkali-treated polyester and cotton fabrics as substrates, respectively. The results showed that since the substrates became hydrophilic products, the contact coolness coefficient (Q max ) of the fabrics in a wet state increased, which damaged the thermal insulation performance.
织物的水分残留量及接触凉感系数测量方法：Measurement method of fabric moisture residue and contact coolness coefficient:
使用中国宁波纺织仪器有限公司的NF3031纺织品接触瞬间凉感测试仪对不同含水量织物(20cm×20cm)的接触凉感系数(Qmax)值进行了测量。The contact cooling coefficient (Q max ) values of fabrics (20 cm×20 cm) with different moisture contents were measured using the NF3031 textile instantaneous cooling tester produced by Ningbo Textile Instrument Co., Ltd., China.
织物的水分残留量测试方法：Test method for residual moisture in fabrics:
通过在涂层侧滴加相同的水量，当水分由涂层侧转移至非涂层侧后，称量织物下方培养皿中的水滴重量，得出水分残留比例(RWC)，计算公式为：By dropping the same amount of water on the coated side, when the water is transferred from the coated side to the non-coated side, the weight of the water drop in the petri dish under the fabric is weighed to obtain the residual water content (RWC), which is calculated as follows:
其中M1是滴加水的质量M2通过织物后剩余水的质量，其中M1统一为1.250g，涤纶的M2为1.210g，碱处理涤纶的M2为0.775g，棉织物的M2为0.195g。Where M1 is the mass of water added and M2 is the mass of water remaining after passing through the fabric, where M1 is uniformly 1.250 g, M2 for polyester is 1.210 g, M2 for alkali-treated polyester is 0.775 g, and M2 for cotton fabric is 0.195 g.
