Example 2
The intelligent moisture absorption and sweat releasing imaging process comprises the following steps:
firstly, sweat moistening: the fabric and the liquid contact the wetting link, quickly wet sweat and form a capillary channel.
Secondly, sweat absorption: the liquid absorption is a link where liquid is rapidly absorbed by the fabric through wicking.
Thirdly, guiding sweat: and the liquid conveying link guides the liquid from the inner part of the fabric skin-friendly layer to the outer layer of the fabric.
Fourthly, sweating: the liquid is separated from the link of the fabric (the moisture in the sweat is separated from other components), the sweat in the inner layer of the fabric is absorbed to the outer layer of the fabric and is evaporated from the outer layer of the fabric, and the moisture is transported and dried quickly; after the human body sweats, the sweat is not diffused on the inner surface of the fabric, but is directly absorbed to the outer layer by the fabric and is evaporated on the outer layer of the fabric so as to keep the inner layer of the fabric relatively dry, reduce the adhesion effect between the human body and the fabric and improve the comfort and the motion function of the human body.
The fabric has the characteristics of perspiration removal: (1) sweat can be rapidly conveyed from the skin surface layer to the fabric surface layer and cannot flow back; (2) the sweat can be discharged while the sweat is conveyed, and the surface layer can absorb a large amount of moisture and evaporate a large amount of moisture; (3) sweat does not enter the internal structure of the fiber, but is evaporated on the surface of the fabric in a large area, and the fabric is dried quickly.
Fifthly, micro-ecology control: and (3) an intelligent control link of the overall fabric taking efficiency. Besides the moisture absorption and sweat releasing functions of the fabric from inside to outside, the invention applies the environment-friendly ecological hydrophobic auxiliary agent to carry out micro window printing finishing on the skin-friendly surface of the fabric. When the skin sweats, the sweat is quickly led into the non-printed super-hydrophilic groove grids and is instantly siphoned to the space outside the fabric along the grooves to be quickly volatilized, so that quick drying is realized; the skin-sticking water-repellent part is dry, liquid can not flow backwards, and the image is in a block shape. The hydrophilic grooves are communicated with each other, so that sweat can permeate out quickly.
According to different application scenes, different states of human body sweating and the moisture absorption and sweat releasing performance of fabric fibers, different hydrophobic area ratios are designed in the unit area of the fabric:

Example 3
The structural characteristics and functional structure requirements of the fabric are as follows:
first, the efficacy goals for fabric wear: the invention is beneficial to realizing better matching of the heat-moisture balance and the comfort of the skin through different application scenes and the control of the hydrophobic area ratio of the skin-friendly surface. The fabric has improved the "microclimate" between fabric and the skin through more accurate control and heat release to the sweat, and then better control skin "microecology" environment, the protection is healthy:
(1) moisture-heat balance: sweat is led out of the fabric quickly, and redundant heat is dissipated, so that body feeling comfort is brought, and human health is facilitated.
(2) And (3) flora balance: the sweat moisture is quickly separated out and does not seep back, or the sweat moisture retention time on the skin is shortened, the mixing time of bacteria and the sweat and the growing environment are controlled, and the balance of the flora on the surface of the skin is facilitated;
(3) water-oil balance: the traditional Chinese medicine considers that sweat is one of body fluids of human body, and the sweat has the function of moistening skin, and is not discharged as dry as possible. A proper amount of sweat on the skin is beneficial to the ecological balance of the skin flora. The fabric is designed with hydrophilic grooves, so that not only can sweat be guided, but also a proper amount of water can be retained, excessive dehydration and dryness of the skin can be avoided, the skin can be moistened, an acid protective film of the skin can be maintained, and the invasion of bacteria can be prevented.
(4) Controlling the smell: organic matters and inorganic matters in sweat are quickly transferred along with moisture, and are not mixed with bacteria for a long time to generate peculiar smell, so that the smell is controlled;
(5) and (4) observing pathology: when a human body sweats pathologically, different pathological sweating parts are different (for example, a large amount of sweating on the chest part can be a spleen and stomach problem). Sweat can be quickly discharged out of the fabric permeation surface, so that people can be helped to observe and predict pathology more quickly.
(6) Developing and anti-counterfeiting: the fabric has the function of developing when the fabric is sweaty, so that the aesthetic feeling of the fabric is improved, the anti-counterfeiting effect is also realized, and the quality is ensured.
II, a fabric functional structure:
(1) moisture sweat functional structure:
the first mechanical condition that the fiber is completely wetted is to puncture a water film and eliminate the influence of an air molecular film on the surface of the fiber, mainly on the skin-facing surface of the fabric. Secondly, several fibers approach each other and are wetted simultaneously to form capillary water transport channels. So that a considerable amount of the fibers on the inner surface of the fabric will penetrate the droplets and be wetted for further water transport.
(2) Sweat-absorbing functional structure:
mainly on the skin-facing surface of the fabric, the requirements of water absorption and water non-retention of the inner layer of the fabric are comprehensively considered, the fabric is made of fibers with wettability (wetting angle of 50-65 degrees to distilled water), and the aim of quickly absorbing water is fulfilled by increasing the void ratio.
The skin-attached surface of the inner layer of the fabric is not in close contact with the skin of a human body, and a proper microclimate area is reserved between the skin-attached surface and the skin-attached surface, so that the garment is not attached to the surface of the human body, and the sanitation is guaranteed. The inner surface of the fabric has certain unevenness or fluffiness, the fibers are soft and have no piercing and rolling, but can pierce a water film and can be slightly napped, and the inner side of the fabric is contacted with a human body in a point-like manner to contact with the skin and absorb water. The inner layer is made into an uneven surface, the fabric and a human body can be in point or line contact, and the porosity of the inner layer and the porosity of the middle layer cannot be greatly different in consideration of the requirement of capillary communication.
(3) The sweat guiding functional structure is as follows:
the middle layer of the fabric, which is the main layer of the fabric, absorbs, transfers and stores the liquid to be dissipated from the inner layer. When the permeable surface is lack of water, the water for evaporation is supplemented in time. The design requires fast water absorption, the fiber material should have excellent wettability (wetting angle is below 60 degrees), the water absorption time is short, the capillary channel is well communicated with the inner layer of the fabric, the fiber arrangement is relatively regular and orderly, and the porosity is low. If the capillary force between the fibers of the middle layer is larger than that between the fibers of the inner layer, the liquid left in the inner layer can be transferred by the middle layer, the dryness in the fabric is kept, and the liquid is prevented from spreading and sticking. To meet this requirement, the middle layer fibers are selected from the group consisting of the fibers that are easily wettable, and the porosity of the aggregate is also appropriately reduced, and the capillary attraction of the middle layer is increased by reducing the equivalent radius of the capillary. In addition, the middle layer fabric also has certain water retention capacity.
(4) The sweat-removing functional structure is as follows:
the fiber has good wettability and larger surface area on the permeable surface of the fabric; the outer surface can be uneven, and the evaporation efficiency is higher; the capillary water delivery pipeline is communicated with the middle layer. The outer layer and the middle layer of the fabric are connected well, and the middle layer of the fabric can supplement water in time while water is evaporated.
(5) Controlling the micro-ecological functional structure:
the fabric is mainly the whole, and in the actual invention, each functional structure, namely the fabric skin layer, the middle layer and the penetration surface, has no strict limit as long as the functions are matched and meet the requirements. The invention selects hygroscopic bio-based fibers (such as modal, tencel and the like) and moisture-conductive bio-based fibers (such as polylactic acid fibers and the like) for blending, reasonably designs the functional structure of the fabric, endows the fabric with directional moisture absorption and sweat release functions by physical and chemical means, then applies an environment-friendly hydrophobic auxiliary agent to carry out an intelligent micro-window printing process, controls the moisture absorption and sweat release accurately by controlling the proportion of the hydrophobic printing area, and adapts to various application scenes, thereby achieving the purpose of improving the micro-ecological environment of the skin.
The invention aims to carry out more accurate intelligent regulation and control design on the moisture absorption and sweat releasing functions of the fabric through scientific material selection and reasonable design according to different sweat releasing application scenes of immature groups, not only achieves more satisfactory comfort of heat and humidity balance of the skin of a human body, but also improves the microclimate between the fabric and the skin, improves the micro-ecological environment consisting of sweat, heat, flora, other skin secretions and the like, is beneficial to flora balance, controls peculiar smell generation, protects an acid protective film of the skin, further reduces the health problems of the skin, the upper respiratory tract and the like caused by sweat releasing, lightens the burden of family care, and responds to the national policy of encouraging family growth. The invention is mainly directed to the group of the young people and is also suitable for adults with the same or similar requirements.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
