Definitions

  • the invention belongs to the field of labor protection appliances, in particular to a fully soaked glove with the function of moisture absorption and perspiration.
  • the object of the present invention is to provide a fully soaked glove with moisture absorption and perspiration function.
  • the principle of waterproof and moisture absorption and ventilation of the coating is: there are two ways of moisture absorption and ventilation of the film, one is non-porous and hydrophilic.
  • Water molecules are composed of one oxygen atom and two hydrogen atoms. When the water molecules are in the gaseous state, there is almost no force between the molecules, and the water molecules can move freely.
  • the hydrophilic groups contained in the film can absorb water molecules, and conduct from the inner layer with high concentration to the outer layer with low concentration through the molecular chain, and then volatilize into the air to complete an adsorption-transfer-- The complete process of desorption.
  • the shielding layer produces moisture absorption and air permeability.
  • concentration and temperature difference of water molecules inside and outside the shielding layer are the influencing factors of the conduction rate. The greater the difference, the faster the conduction rate.
  • the bonding force between molecules is relatively large, including van der Waals force and hydrogen bonds, so although the hydrophilic groups in the film are in contact with liquid water, the shielding layer is not in contact with water.
  • the adsorption force of molecules is smaller than the binding force between water molecules, so liquid water cannot be transmitted to the other side through the shielding layer, and the shielding layer plays a role of waterproofing at this time.
  • the shielding layer is a non-porous design, bacteria and viruses cannot pass through the shielding layer, which is the principle that the shielding layer is not only breathable, but also waterproof and anti-virus.
  • the second method of moisture absorption and ventilation of the film is the micropore dredging method.
  • the moisture absorption and ventilation layer of the present invention adopts this method. When the wearer's hands produce sweat, the volume of gaseous water molecules is much smaller than the aperture of the micropores, so it can Freely contact the shielding layer through the moisture-absorbing and breathable layer, and then diffuse to the outside of the glove through the shielding layer.
  • the microporous moisture-absorbing and breathable coating can temporarily absorb and store excess sweat.
  • the moisture-absorbing and breathable coating of the present invention also has hydrophilic groups at the same time, so it has both microporous hydrophobic and hydrophilic moisture-absorbing functions, and can slow down or even eliminate the stuffy and wet feeling of hands caused by sweat as much as possible. .
  • the hydrophilic properties of the coating in contact with the skin and the number of micropores are the key.
  • the raw materials of full-immersion coating products on the market are nitrile or PVC. From the analysis of the structures of these two raw materials, the hydrophilicity is relatively poor, especially PVC materials, which do not have hydrophilicity at all. According to the analysis of the process, these two materials do not have a foaming process and a foaming section. Therefore, the hydrophilicity and micropores of the fully-immersed coated gloves produced with these two materials are not enough, or even not, resulting in gloves that do not have moisture absorption. effect, and the hand feel is relatively hard.
  • This patent uses polyurethane as the raw material of the inner layer, which solves the problems of hydrophilicity, moisture absorption and perspiration from the chemical composition and physical structure.
  • the polyurethane raw materials currently on the market are divided into two types, solvent-based and water-based, and no matter which type, they all have a certain number of hydrophilic groups-carboxyl, hydroxyl or amino groups. , these groups can strongly adsorb gaseous water molecules. From the point of view of physical structure, during the process of water-washing and film-forming of solvent-based polyurethane after dipping, due to the exchange of solvent and water, the resulting polyurethane film forms a large number of fine holes.
  • the processing technology of physical foaming before, so that the water-based polyurethane also contains a large number of fine cells.
  • These fine cells have two advantages.
  • One is that the specific surface area of the coating is greatly increased, that is, the contact area between water molecules and hydrophilic materials is increased.
  • the gaseous sweat can Maximize the contact with the hydrophilic groups of the coating and be absorbed, and then be channeled to the outside of the glove through the shielding layer. If the sweat is produced faster than it is discharged, the excess sweat will be attracted by a large number of microporous capillaries, And held by the coating and fibers, mechanically held in capillaries between fibers.
  • Second because there are a large number of tiny holes, the softness of the coating is greatly improved. This is a very important indicator in the actual use of gloves. Soft gloves can well reduce hand fatigue during work and reduce labor intensity to the greatest extent.

  • the low surface energy can make the shielding coating material soak into the surface of the moisture-absorbing and air-permeable layer or even the micropores of the surface layer to the greatest extent, through sufficient interfacial contact, it will be absorbed by the moisture-absorbing and air-permeable layer.
  • the moisture-absorbing and breathable layer molecules are closely combined, and the two-layer coating forms a stable state under the joint action of van der Waals force and hydrogen bonds. Therefore, strictly controlling the surface energy of the shielding layer is to make the two-layer coating have The key to high bond strength.

If the moisture-absorbing and air-permeable layer is made of water-based polyurethane, we believe that the expansion rate is between 1.15 and 1.8, which is a reasonable range, and the number and diameter of cells can be controlled by the amount of foaming agent added.

Description

带吸湿排汗功能的全浸手套 技术领域
本发明属于劳保用具领域，尤其涉及一种带吸湿排汗功能的全浸手套。
背景技术
众所周知，在现代化的工业生产中，安全防护是相当重要的，而佩戴防护手套就是安全防护的的一个重要组成部分。目前市场所售涂层型劳保安防手套，分为全浸型和掌浸型。掌浸型劳防手套，涂层主要成分有丁腈，天然乳胶，PVC和聚氨酯。佩戴此类手套可以起到一定的防护作用，但因手背没有涂层，因而对于外界的液体或细菌侵入则无能为力。针对某些特殊场合，比如工作环境比较潮湿甚至有润滑油之类的油污，或者接触医疗废弃物等等有细菌或病毒侵入风险的场合，均需要在手部和外界物体之间保持良好的屏蔽隔绝涂层，掌浸型涂层手套显然不适合，必须佩戴全浸型手套。全浸型手套的涂层主要原料有丁腈，天然乳胶，PVC，正因为需要屏蔽外界液体或细菌侵入，因此目前所有此类市售产品均无吸湿透气的功能，且手感比较疆硬，佩戴时会有非常不舒服的体验感，长时间使用，手部皮肤浸泡在汗液中，容易使皮肤产生褶皱，而且还非常容易滋生细菌，同时增加了工作的疲劳强度。
发明内容
本发明的目的是提供一种带吸湿排汗功能的全浸手套。
发明人经过研究发现：涂层的防水与吸湿透气的原理为：薄膜的吸湿透气方式有二种，一是无孔亲水方式。水分子都是由一个氧原子和二个氢原子组成的，当水分子处于气态时，分子与分子之间几乎没有作用力，水分子可以自由运动，当屏蔽层内部的水分子以气态形式与薄膜接触时，薄膜中所含的亲水基团可以吸附水分子，并通过分子链由浓度高的内层传导到浓度低的外层，进而挥发到空气中，完成一个吸附--转移--解吸附的完整过程。此时屏蔽层就产生了吸湿透气现象，屏蔽层内外部水分子的浓度和温度差异是传导速率的影响因素，差异越大，传导速度越快。但是当水分子处于液态时，分子与分子之间的 结合力是比较大的，既有范德华力，又有氢键，因此薄膜中的亲水基团与液态水虽然接触，但屏蔽层与水分子的吸附力小于水分子相互之间的结合力，因此液态水是无法通过屏蔽层传导到另一面的，此时屏蔽层就起到了防水的作用。另外，因为屏蔽层是无孔设计，细菌和病毒无法通过屏蔽层，这就是屏蔽层既能透气，又能防水和防病毒的原理。薄膜吸湿透气的第二种方式是微孔疏通方式，本发明的吸湿透气层就是采用这个方式，当佩戴者手部产生汗气时，由于气态水分子的体积远小于微孔的孔径，所以可以自由通过吸湿透气层与屏蔽层接触，进而通过屏蔽层扩散至手套外部，但时，如果产生的汗气量大于屏蔽层的扩散速度时，微孔型的吸湿透气涂层就可以暂时吸附和贮存多余的汗气。另外本发明的吸湿透气涂层同时自身也带有亲水基团，因此它是同时兼备微孔疏水和亲水吸湿功能的，尽可能减缓甚至消除由于汗气导致的手部闷和湿的感觉。
根据以上原理，与皮肤接触的涂层的亲水性能以及微孔数量是关键。目前市售全浸型涂层产品的原料为丁腈或PVC,从这二种原料本身的结构来分析，亲水性比较差，特别是PVC材料，根本就不具备亲水性，再从加工工艺来分析，这两种材料也没有发泡工艺和发泡工段，因此用这二种原料生产的全浸理型涂层手套的亲水性及微孔不够，甚至没有，导致手套不具备吸湿效果，且手感比较疆硬。
本专利采用聚氨酯为内层原料，从化学组成和物理结构上很好地解决了亲水和吸湿排汗的问题。首先从化学组成来看，目前市场所售的聚氨酯原料分为二种类型，溶剂型和水性型，而不论哪一种类型，他们都具有一定数量的亲水基团--羧基、羟基或氨基，这些基团可以强烈吸附气态的水分子。从物理结构来看，溶剂型聚氨酯在浸胶后的水洗成膜过程中，由于溶剂和水和交换，所成的聚氨酯膜形成了大量的细微孔洞，而对水性型聚氨酯，我们采用了在成型前就物理发泡的加工工艺，从而使水性聚氨酯也含有大量的细微泡孔。这些细微的泡孔有二个好处，一是极大地增加了涂层的比表面积，也就是增加了水分子和亲水材料的接触面积，这样，在手套的使用过程中，气态的汗水，可以最大程度地和涂层的亲水基团接触并被吸附，进而通过屏蔽层疏导到手套外部，如 果汗水产生的速度大于被排出的速度，那么多余的汗水就会被大量的微孔毛细管引力，并被涂层和纤维握持，机械地保持在纤维间的毛细管中。二是因为有大量的细微孔洞，极大地提升了涂层的柔软度。这在手套的实际使用过程中是一个相当重要的指标，柔软的手套可以很好的减轻工作中手部的疲劳感，最大程度减轻劳动强度。
本发明是通过以下技术方案来实现的：
带吸湿排汗功能的全浸手套，包括针织的手芯本体和全浸涂覆于手芯本体内表面的吸湿透气层和全浸涂覆于手芯本体外表面的屏蔽层，吸湿排汗层和屏蔽层均采用主要原料包括水性聚氨酯或溶剂型聚氨酯的涂料制备，所述吸湿排汗层为发泡层，厚度为0.1—0.3毫米；所述屏蔽层为不发泡层，厚度为0.03—0.2毫米；所述全浸手套的具体制备工艺包括：手芯本体套模→浸胶制备发泡的吸湿透气层→水洗→烘干→浸胶制备不发泡的屏蔽层→烘干→成品脱模→包装，其中：在浸第二层胶即屏蔽层时，确保第一层的吸湿透气层已经固化并且烘干成膜，确保让还处于液态的屏蔽层涂料的表面能低于吸湿透气层的表面能，以使屏蔽涂层料最大程度地浸润到吸湿透气层表面甚至表层微孔内。因为低表面能可以使屏蔽涂层料最大程度地浸润到吸湿透气层表面甚至表层微孔内，通过充分的界面接触，被吸湿透气层吸附，在随后的加热过程中，屏蔽层胶料分子在布朗运动的作用下，和吸湿透气层分子紧密结合在一起，二层涂层在范德华力和氢键的共同作用下形成一个稳定状态，因此严格控制屏蔽层的表面能是使两层涂层具有高粘接强度的关键。
作为优选，为确保所述屏蔽层的厚度为0.03—0.2毫米，当所述屏蔽层的制备材料主要包括水性聚氨酯树脂时，控制涂料固含量在20-40％，粘度在500—2000厘泊之间；当所述屏蔽层的制备材料主要包括溶剂型聚氨酯树脂时，控制涂料固含量在12-20％，粘度在300—1500厘泊之间。
更优地，当所述屏蔽层的制备材料主要包括水性聚氨酯树脂时，制备的原料包括如下组分：水性聚氨酯乳液，消泡剂,增稠剂，固化剂，润湿剂；
当所述屏蔽层的制备材料主要包括溶剂型聚氨酯树脂时，制备的原料包括 如下组分：干法聚氨酯树脂，DMF，消泡剂，流平剂，渗透剂，润湿剂。
进一步地，当所述屏蔽层的制备材料主要包括水性聚氨酯树脂时，制备的原料包括如下组分及质量份：水性聚氨酯乳液1000质量份，消泡剂4--7质量份,增稠剂3--8质量份，固化剂10--30质量份，润湿剂2--5质量份；当所述屏蔽层的制备材料主要包括溶剂型聚氨酯树脂时，制备的原料包括如下组分及质量份：干法聚氨酯树脂1000质量份，DMF 800--2000质量份，消泡剂3--10质量份，流平剂3--8质量份，渗透剂3--8质量份，润湿剂2--5质量份。
作为优选，为确保所述吸湿透气层的厚度为0.1—0.3毫米，当所述吸湿透气层的制备材料主要包括水性聚氨酯树脂时，控制涂料固含量在20—40％，粘度在500—2000厘泊，控制发泡的倍率在1.15—1.8之间；因为，对水性聚氨酯树脂来说，涂料固含量在20—40％，粘度在500—2000厘泊之间，就可以实现将涂层厚度自由控制在0.1—0.3毫米之间；
当所述吸湿透气层的制备材料主要包括溶剂型聚氨酯时，控制涂料固含量为12--18％，粘度在500--1500厘泊；因为，根据溶剂型树脂的发泡原理，可以通过调整树脂固含量，加入凝固速度调整剂和泡孔调整剂来，通过加入凝固速度调整剂，可以改变树脂入水后的凝固速度，使得表面层树脂致密度下降，同时加入泡孔调整助剂，减少大孔径泡孔的产生概率，而涂料固含量的控制范围，则控制在12—18％是比较合适的，同时控制粘度在500--1500厘泊之间，可以实现将涂层厚度自由控制在0.1—0.3毫米之间。
更优地，当所述吸湿透气层的制备材料主要包括水性聚氨酯树脂时，制备的原料包括如下组分：水性聚氨酯乳液、发泡剂和增稠剂，发泡剂的加入量为水性聚氨酯乳液质量的5—15％；
当所述吸湿透气层的制备材料主要包括溶剂型聚氨酯时，制备的原料包括如下组分：湿法聚氨酯树脂，DMF，消泡剂，渗透剂，泡孔助剂，促进剂,涂料固含量控制在12—18％。因为，根据溶剂型树脂的发泡原理，可以通过调整树脂固含量，加入凝固速度调整剂和泡孔调整助剂来，通过加入凝固速度调整剂， 可以改变树脂入水后的凝固速度，使得表面层树脂致密度下降，同时加入泡孔调整助剂，减少大孔径泡孔的产生概率，而涂料固含量的控制范围，则控制在12—18％是比较合适的。
进一步地，当所述吸湿透气层的制备材料主要包括水性聚氨酯时，制备的原料包括如下组分及质量份：水性聚氨酯乳液1000质量份，发泡剂50--150质量份，增稠剂2--6质量份；

制作全浸手套时吸湿排汗层和屏蔽层各采用何种原料配方可以根据需要任意组合。
之所以选择如上的参数，原因如下：
一：对于吸湿透气层来说，需要注意二个要点。
1：泡孔的大小和数量。单位体积的吸湿透气涂层的泡孔在合理的范围内，如果数量越多，则孔径越小，说明泡孔的比表面积越大，这对吸湿透气来说是有利的，(这里需要说明的是泡孔孔径的小是不小于阻碍水气分子自由通过的范围)。如果吸湿透气层是用水性聚氨酯来制备，我们认为发泡的倍率在1.15—1.8之间是比较合理的范围，泡孔的数量和孔径可以通过发泡剂的加入量来控制。发泡剂的加入量一般为树脂量的5—15％。如果吸湿透气层是用溶剂型聚氨酯来制备，根据溶剂型树脂的发泡原理，可以通过调整涂料固含量，加入凝固速度调整剂和泡孔调整剂来实现我们所需的目标，传统的溶剂型聚氨酯手套用树脂，入水后表面的凝固速度非常快，导致涂层表面非常致密，类似于塑料表皮，通过加入凝固速度调整剂，可以改变树脂入水后的凝固速度，使得表面层树脂致密度下降，同时加入泡孔调整助剂，减少大孔径泡孔的产生概率，而涂料固含量的控制范围，则控制在12—18％是比较合适的。综合上述三个因素，可以使得整个吸湿透气层的比表面积控制在比较合理的范围内。
2:涂层的厚度，对于吸湿透气层来说，因为有数量极多的细微孔洞，对于透气度来说涂层的厚薄稍有影响，因为厚度越厚，水分子穿过涂层的路径就会加长，不利于透气。对于吸湿度来说，在单位体积泡孔数量恒定的前提下，涂层越厚，也就是可以用来吸收和锁定水份的贮存空间就越多，因此对吸湿是有利的，但是和屏蔽层一样，越厚的涂层对于手指的灵活度和触感也起负面影响，通过认证，我们认为涂层的厚度控制在0.1—0.3毫米之间是比较合适的。在具体制定生产工艺时，涂层厚度可以通过调整涂料的粘度和固含量来实现，同样的粘度，涂料的固含量越高，涂层的厚度越厚。同样的固含量，涂料的粘度越高，涂层越厚。对水性聚氨酯树脂来说，涂料固含量在20—40％，粘度在500—2000厘泊之间，控制发泡的倍率在1.15—1.8之间，就可以实现将涂层厚度自由控制在0.1—0.3毫米之间。而对于溶剂型聚氨酯来说，涂料固含量在12--18％，粘度在500--1500厘泊之间，可以实现将涂层厚度自由控制在0.1—0.3毫米之间。
二：对于屏蔽层来说，我们需要严格控制涂层的厚度。厚的涂层，对屏蔽效果是有利的，缺点是对于透气来说，水分子通过屏蔽层的路径就加长，降低了涂层的透气性能，另外佩戴者在工作过程中，厚的涂层对于手指的灵活度和触感也起负面影响。薄的涂层，水分子通过屏蔽层的路径就变短，增加了涂层的透气性能，而且触觉灵敏，缺点是持续的屏蔽效果有降低的可能性，另外，对于手套的耐用性也会产生比较严重的负面影响。因此选取一个合适的涂层厚度是比较关键的，通过认证，认为涂层的厚度控制在0.03—0.2毫米之间是比较合适的。具体生产工艺制定中，涂层厚度同理可以通过调整涂料的粘度和固含量来实现，对水性聚氨酯树脂来说，涂料固含量在20-40％，粘度在500—2000厘泊之间，对溶剂型聚氨酯来说，涂料固含量在12-20％，粘度在300—1500厘泊之间，就可以实现将涂层厚度自由控制在0.03—0.2毫米之间。
三：吸湿透气层和屏蔽层的粘接强度。粘接的原理是二层被粘物相互接触后，分子间产生作用力，从而使二个被粘物结合在一起。具体到本发明工艺， 在浸第二层胶(屏蔽层)时，第一层吸湿透气层已经固化并且烘干成膜，要提高吸湿透气层和屏蔽层的结合强度，就必须要让还处于液态的屏蔽层涂料的表面能低于吸湿透气层的表面能，因为低表面能可以使屏蔽涂层料最大程度地浸润到吸湿透气层表面甚至表层微孔内，通过充分的界面接触，被吸湿透气层吸附，在随后的加热过程中，屏蔽层胶料分子在布朗运动的作用下，和吸湿透气层分子紧密结合在一起，二层涂层在范德华力和氢键的共同作用下形成一个稳定状态，因此严格控制屏蔽层的表面能是使两层涂层具有高粘接强度的关键。
本发明的有益效果是：
本发明的带吸湿排汗功能的全浸手套，结构巧妙，针对目前市场上各种手套存在的不足之处，本发明专利采用二次浸胶的方式，创造性地做到把吸湿透气和屏蔽隔绝功能合成到一个手套上，完美解决市场痛点。本专利手套产用聚氨酯作为涂层原料，把发泡涂层(主要起到吸湿透气功能)和不发泡涂层(主要起到屏蔽隔绝功能)有机结合在一起，从而使产品兼具吸湿透气和屏蔽隔绝功能，而且手感柔软，大大减轻了工作的疲劳感，适用范围更广，实用性强，值得推广。
