[0017] Firstly, the raw cotton fibers are subjected to semi-degreasing treatment, and then the treated raw cotton fibers are laid to obtain a raw cotton net; the semi-degreasing treatment means that the raw cotton fibers have been partially degreased, but not completely degreased;
[0018] Secondly, the wormwood fibers are laid to obtain a wormwood net, and the length of the wormwood fibers is greater than that of the raw cotton fibers;
[0019] Thirdly, the wormwood net is laid flat on the raw cotton net to obtain a composite net, the mass fraction of the wormwood fibers in the composite net is 40%-60%, and then the composite net is subjected to forward spunlace, the jet of the forward spunlace is directly opposite to the top of the wormwood net, and in the process of forward spunlace, part of the wormwood fibers in the wormwood net are pierced into the raw cotton net by the jet, and then the spunlace net is obtained after the forward spunlace is completed;
[0020] Fourthly, the spunlace net is dried, and then cut as needed to obtain the moisture-absorbing and breathable medical dressing containing wormwood components.
[0021] In the forward water jetting process, the bottom of the cotton fiber net in the lower layer of the composite net is in contact with the supporting net curtain, the composite net moves forward synchronously with the supporting net curtain, and the jet penetrating the composite net is bounced by the supporting net curtain to form a reverse jet, which is shot to the composite net again from bottom to top.
[0022] In the first step, the semi-defatting treatment refers to soaking the cotton fiber in a hydrogen peroxide activation treatment solution for 2-3 hours.
[0023] The composition and content of the hydrogen peroxide activation treatment solution are as follows: the concentration of H2O2 is 2-3 g / L, the concentration of inorganic alkali is 1-2 g / L, and the concentration of tetraacetyl ethylenediamine is 1-2 g / L.
[0024] The inorganic alkali refers to any one or any mixture of sodium bicarbonate, sodium carbonate, potassium carbonate, sodium thiosulfate, sodium hydroxide, lithium hydroxide, potassium hydroxide, ammonia, aluminum hydroxide, and barium hydroxide.
[0025] The inorganic alkali refers to sodium bicarbonate.
[0026] The treatment temperature is 50-60 DEG C.
[0027] The soaking of the cotton fiber in the hydrogen peroxide activation treatment solution refers to mixing the cotton fiber with the hydrogen peroxide activation treatment solution at a bath ratio of 1:20.
[0028] In the second step, the length of the wormwood fiber is 35-40 mm, and the length of the cotton fiber is 25-35 mm.
[0029] In the third step, the gram weight of the wormwood net is 40-60 g / m 2 , and the gram weight of the cotton net is 40-60 g / m 2 .
[0030] In the first step, the laying of the treated cotton fiber to obtain a cotton net refers to first opening the treated cotton fiber, and then laying the opened cotton fiber to obtain a cotton net.
[0031] In the second step, the laying of the wormwood fiber to obtain a wormwood net refers to first opening the wormwood fiber, and then laying the opened wormwood fiber to obtain a wormwood net.
[0032] Compared with the prior art, the beneficial effects of the present application are:
[0033] 1. The production method of the moisture-absorbing and air-permeable medical dressing containing wormwood components, wherein the wormwood net is first laid on the raw cotton net to obtain a composite net, the mass ratio of the wormwood fibers in the composite net is 40%-60%, and then the composite net is subjected to forward hydroentanglement from top to bottom, the jet of the forward hydroentanglement first shoots at the wormwood net, and then continues to penetrate until it shoots through the raw cotton net, in the whole process of the forward hydroentanglement, the wormwood fibers and the raw cotton fibers are driven downward by the jet to intertwine with each other, and the firmness of the composite net is improved, and the design has the following advantages:
[0034] Firstly, the mutual intertwining of the wormwood fibers, the mutual intertwining of the raw cotton fibers, and the mutual intertwining between the wormwood fibers and the raw cotton fibers all can enhance the bonding force between the wormwood fibers and the raw cotton fibers, so that the effective components in the wormwood fibers will not fall off during storage, and the effective components will not be easily washed away by the human body blood or tissue fluid during use, and the normal play of the wormwood pharmacological effect is facilitated.
[0035] Secondly, under the impact of the forward hydroentanglement from top to bottom, the density of the raw cotton net at the bottom is increased to form a density difference of upper loose and lower dense in the longitudinal direction, so that the one-way wetting effect is formed, the absorption of the dressing to the human body tissue fluid or blood is facilitated, and the medical effect of the dressing is improved.
[0036] Thirdly, the one-way wetting effect from bottom to top is more conducive to the liquid directly reaching the wormwood net at the upper layer, so that the effective components in the wormwood fibers are dissolved out, and then the effective components are penetrated into the raw cotton fibers at the lower layer to perform antibacterial medical treatment on the treated part, and meanwhile, the wormwood fibers at the upper layer can also perform antibacterial treatment on the external environment to form an internal and external antibacterial effect.
[0037] Fourthly, the raw cotton net at the bottom layer directly contacts the wound, the natural crimp structure of the cotton fibers makes the cotton fibers more fluffy and better in air permeability than the wormwood viscose fibers, and the raw cotton fibers as natural cellulose fibers are good in skin affinity and comfort, and can be close to the wound.
[0038] Therefore, the present application not only has strong bonding force, is good in wormwood pharmacological effect play and close to the wound, but also has good moisture absorption effect, strong antibacterial effect and strong air permeability.
[0039] 2、The production method of the moisture-absorbing and air-permeable medical dressing containing artemisia ingredient in the application, the raw cotton fiber in the raw cotton net refers to the fiber after semi-defatted treatment, although the hydrophobicity is reduced, but the moisture absorption performance is lower than that of the artemisia net, thereby constructing a layer structure with gradually weak moisture absorption effect from top to bottom in the composite net, and part of the artemisia fiber is stabbed into the raw cotton net during water needling, the artemisia fiber has a tendency to be more deeply intertwined into the raw cotton fiber due to the longer length, and a moisture guide channel penetrating into the cotton fiber layer is formed in the microstructure, so that the liquid moves unidirectionally along the artemisia fiber with good hydrophilicity under the action of the interfacial force provided by the wetting gradient, a unidirectional moisture guide effect from bottom to top is formed, the moisture guide efficiency is higher, not only the moisture absorption effect can be improved, but also the dissolution of the effective component in the upper artemisia fiber is beneficial to further penetrate into the inner raw cotton net, the raw cotton net plays a role of storage and slow release for the artemisia component, compared with directly contacting the skin, there is an additional role of the raw cotton net, so it is more durable and more beneficial to the exertion of the artemisia pharmacological effect. Therefore, the unidirectional moisture guide effect is stronger, and the exertion of the artemisia pharmacological effect is better.
[0040] 3、The production method of the moisture-absorbing and air-permeable medical dressing containing artemisia ingredient in the application, the composition and content of the hydrogen peroxide activation treatment solution are as follows: the concentration of H2O2 is 2-3 g / L, the concentration of inorganic alkali is 1-2 g / L, and the concentration of tetraacetyl ethylenediamine is 1-2 g / L, wherein the concentration of each substance is selected to promote the realization of semi-defatting, and at the same time, the use of chemical agents is reduced, the cost is reduced, and the environmental protection is improved; in addition, sodium bicarbonate is preferably selected as the inorganic alkali, which has weaker alkalinity and is more beneficial to the realization of semi-defatting. Therefore, the semi-defatting of the raw cotton fiber can be realized, and the cost is lower and the environmental protection is stronger.
[0041] 4、The production method of the moisture-absorbing and air-permeable medical dressing containing artemisia ingredient in the application, the treatment temperature of semi-defatting treatment is preferably 50-60℃, which can control the reaction temperature below the melting point of the oil and fat impurities in the raw cotton fiber, avoid high-temperature melting of too much oil and fat impurities, and expect to remove part of the pectin and cotton wax and other oil and fat substances through saponification reaction in an alkaline environment, which is more beneficial to the realization of semi-defatting. Therefore, the saponification reaction is preferably adopted to defat the raw cotton fiber in the application, and the semi-defatting effect is better. BRIEF DESCRIPTION OF DRAWINGS

[0044] Reference Figure 1A production method of a moisture-absorbing and air-permeable medical dressing containing artemisia fiber, the production method comprising the following steps:
[0045] In the first step, the raw cotton fibers are subjected to semi-defatting treatment, and then the treated raw cotton fibers are laid to obtain a raw cotton web; the semi-defatting treatment means that the raw cotton fibers have been partially defatted but not completely defatted;
[0046] In the second step, artemisia fibers are laid to obtain an artemisia web, and the length of the artemisia fibers is greater than that of the raw cotton fibers;
[0047] In the third step, the artemisia web is first laid on the raw cotton web to obtain a composite web, the mass fraction of the artemisia fibers in the composite web is 40%-60%, and then the composite web is subjected to forward hydroentanglement, the jet of the forward hydroentanglement is directly opposite to the top of the artemisia web, in the process of the forward hydroentanglement, part of the artemisia fibers in the artemisia web are penetrated into the raw cotton web by the jet, and then a hydroentangled web is obtained after the forward hydroentanglement is completed.
[0048] In the fourth step, the hydroentangled web is first dried, and then cut as needed to obtain the moisture-absorbing and air-permeable medical dressing containing artemisia fiber.
[0049] In the process of the forward hydroentanglement, the bottom of the lower raw cotton web in the composite web is in contact with the supporting net curtain, the composite web moves forward synchronously with the supporting net curtain, and the jet penetrating through the composite web is bounced by the supporting net curtain to form a reverse jet, the reverse jet is shot to the composite web again from bottom to top.
[0050] In the first step, the semi-defatting treatment means that the raw cotton fibers are soaked in a hydrogen peroxide activation treatment solution for 2-3 hours.
[0051] The composition and content of the hydrogen peroxide activation treatment solution are as follows: the concentration of H2O2 is 2-3 g / L, the concentration of inorganic alkali is 1-2 g / L, and the concentration of tetraacetyl ethylenediamine is 1-2 g / L.
[0052] The inorganic alkali refers to any one or any mixture of sodium bicarbonate, sodium carbonate, potassium carbonate, sodium thiosulfate, sodium hydroxide, lithium hydroxide, potassium hydroxide, ammonia, aluminum hydroxide, and barium hydroxide.
[0053] The inorganic alkali refers to sodium bicarbonate.
[0054] The treatment temperature is 50-60°C.
[0055] The soaking of the raw cotton fibers in the hydrogen peroxide activation treatment solution means that the raw cotton fibers are mixed with the hydrogen peroxide activation treatment solution at a bath ratio of 1:20.
[0056] In the second step, the length of the artemisia fibers is 35-40 mm, and the length of the raw cotton fibers is 25-35 mm.
[0057] The third step, the gram weight of the wormwood net is 40-60g / m 2 , the gram weight of the raw cotton net is 40-60g / m 2 .
[0058] The first step, the raw cotton fiber is opened and then laid to obtain the raw cotton net.
[0059] The second step, the wormwood fiber is opened and then laid to obtain the wormwood net.
[0060] The supplementary technical features of the present application are as follows:
[0061] The wormwood fiber in the present application refers to any one of the following:
[0062] The first kind, a kind of natural fiber made of the stems and leaves of wormwood after special processing, the fiber fineness of which is very fine, generally between 5-15 microns, finer than high-strength fiber, thus the hand feeling is very soft and comfortable, and the moisture absorption and air permeability are good.
[0063] The second kind, a kind of fiber containing natural wormwood made by embedding the effective components of wormwood, such as essential oil, into the inside of the fiber in the form of microcapsules after the effective components of wormwood with antibacterial and aromatherapy effects are effectively extracted by modern extraction technology and combined with cotton, lyocell fiber, viscose fiber, and polyamide fiber.
[0064] The one-way wetting effect of the present application: one-way wetting means that liquid will flow from the inner layer to the outer layer, rather than first wetting the inner layer and then penetrating to the outer layer, which is caused by the wetting gradient effect between the two layers. When one side of the material shows a hydrophobic state and the other side shows a hydrophilic state, the liquid will automatically move in a specific direction on the material during the transfer process due to the unbalanced interfacial force on both sides of the material. This process of liquid moving in a specific direction is called wetting gradient effect. Figure 1As shown, the wormwood net is more hydrophilic than the semi-defatted raw cotton net (the untreated raw cotton fiber is hydrophobic due to the coating of pectin and wax, and can only achieve good water absorption after complete defatting, and after semi-defatting treatment, the water absorption of the raw cotton fiber is improved to a certain extent, but it is weaker than the outer layer of the wormwood fiber), the moisture absorption effect is stronger, and the difference in wetting between the inner and outer layers is larger. At this time, combined with the role of the wormwood fiber deep into the raw cotton net as a wet channel (the upper wormwood fiber has a longer length and a deeper tendency to intertwine into the cotton fiber, which will form a wet channel deep into the cotton fiber layer in microcosm), the liquid moves in one direction along the wormwood fiber with good hydrophilicity under the action of the interfacial force provided by the wetting gradient, and the potential energy of the liquid transport is greater, and the wetting efficiency is higher.
[0065] The pharmacological persistence in the application: the wormwood components in the wormwood fiber are coated in the cellulose substrate and located in the wormwood net, which is used as the outer layer of the dressing and does not directly contact the skin. The wormwood components will not quickly dissipate from the fiber interior in the case of dry dressing, and when the dressing contacts the skin, the liquid is transported to the outer layer of the dressing due to the wetting gradient and capillary effect, and the effective components in the wormwood fiber are released into the liquid, but do not directly contact the skin, but are released into the raw cotton net in the inner layer, which stores and releases the wormwood components. Compared with direct contact with the skin, the raw cotton net has an additional effect, so it is more persistent.
[0066] The double antibacterial effect of the application: the wormwood net in the outer layer itself has antibacterial effect, directly preventing the invasion of external bacteria, and the wormwood effective components dissolved by the one-way wetting effect are released into the raw cotton net in the inner layer to exert antibacterial effect on the wound in the inner layer, reducing the growth of bacteria on the affected area and the dressing, so that the inner and outer layers combine to achieve double antibacterial effect.
[0067] Example 1:
[0068] A production method of a moisture-absorbing and air-permeable medical dressing containing wormwood components, the production method comprising the following steps:
[0069] First, the raw cotton fiber is semi-defatted, and then the treated raw cotton fiber is laid to obtain a raw cotton net; the semi-defatting treatment means that the raw cotton fiber has been partially defatted, but not completely defatted, and the defatting rate is preferably 40%-50%; the semi-defatting treatment means that the raw cotton fiber is soaked in a hydrogen peroxide activation treatment solution for 2-3 hours, and generally, after 2-3 hours, the semi-defatting effect is considered to be achieved.
[0070] Second, the wormwood fiber is laid to obtain a wormwood net, and the length of the wormwood fiber is greater than that of the raw cotton fiber;
[0071] Thirdly, the artemisia argyi net is laid on the raw cotton net to obtain a composite net, the mass ratio of artemisia argyi fiber in the composite net is 40%-60%, and then the composite net is subjected to forward water jetting, the jet flow is opposite to the top of the artemisia argyi net, in the process of forward water jetting, part of the artemisia argyi fiber in the artemisia argyi net is jetted into the raw cotton net, and then the water jetting net is obtained after the forward water jetting is completed;
[0072] Fourthly, the water jetting net is dried, and then is cut according to requirements to obtain the artemisia argyi component-containing moisture-permeable medical dressing.
[0073] Example 2:
[0074] The basic content is the same as that in example 1, and the difference is that:
[0075] In the process of forward water jetting, the bottom of the raw cotton net in the lower layer of the composite net is in contact with the supporting net curtain, the composite net moves forward synchronously with the supporting net curtain, and the jet flow that penetrates the composite net is bounced by the supporting net curtain to form a reverse jet flow, the reverse jet flow is jetted to the composite net again from bottom to top.
[0076] When the jet flow is bounced, the water flow energy is weakened and dispersed, the dispersed water flow enters the composite net again from the opposite direction to drive the fibers to move again, but such movement does not affect the layered structure formed by the laying of the net, but makes the fibers move multiple times and entangle more tightly, so that the water jetting cloth has a certain strength, and at the same time, the reverse jet flow is not as concentrated as the jet flow of forward water jetting, so it cannot form obvious moisture-conducting channels.
[0077] Example 3:
[0078] The basic content is the same as that in example 1, and the difference is that:
[0079] The composition and content of the hydrogen peroxide activation treatment solution are as follows: the concentration of H2O2 is 2-3 g / L, the concentration of inorganic alkali is 1-2 g / L, and the concentration of tetraacetyl ethylenediamine is 1-2 g / L; the inorganic alkali refers to any one or any mixture of sodium bicarbonate, sodium carbonate, potassium carbonate, sodium thiosulfate, sodium hydroxide, lithium hydroxide, potassium hydroxide, ammonia, aluminum hydroxide, barium hydroxide, and preferably the inorganic alkali refers to sodium bicarbonate.
[0080] Example 4:
[0081] The basic content is the same as that in example 1, and the difference is that:
[0082] Preferably, in the first step, the treatment temperature of the semi-degreasing treatment is 50-60℃, and further preferably 56℃.
[0083] Example 5:
[0084] The basic content is the same as that in example 1, and the difference is that:
[0085] Preferably, in the second step, the length of the wormwood fibers is 35-40 mm, and the length of the raw cotton fibers is 25-35 mm.
[0086] The above description is merely preferred embodiments of the present application, but the protection scope of the present application is not limited to the above-mentioned embodiments, and any equivalent modifications or changes made by those skilled in the art according to the disclosed content of the present application shall be included in the protection scope of the claims.
