As another embodiment of the present invention, in the multi-functional dry towel of the present invention, the cellulosic fiber web layer may not require any functional ingredient, in which case the cellulosic fiber web layer may be used as a facial towel, for example, for absorbing moisture, wiping sweat, etc.
In order to achieve the object of the present invention, in still another aspect, the present invention provides a method for preparing the multi-functional dry towel as described above, wherein the method comprises the following steps in order:
(1) spraying a first effect layer on the synthetic fiber net layer of the non-woven base fabric and drying;
(2) after the first effect layer is dried, a second effect layer is sprayed on the cellulose fiber web layer of the used nonwoven base fabric and dried.
In the preparation method, the first effect layer and the second effect layer are sprayed by high-pressure water mist nozzles, and the essence is sprayed after being atomized by the high-pressure water mist nozzles. The essence of the effect layer can be sprayed by an adjustable high-pressure water mist nozzle to enable the surface of the carrier layer to absorb.
In the preparation method of the utility model, the high-pressure water mist spray head is preferably a conical spray head, the aperture of the spray nozzle is between 0.1mm and 0.5mm, the pressure is generally 15 to 20 kilograms of force, and the size of the atomized liquid drops is less than 50 microns.
In the preparation method of the utility model, the method further comprises the following steps of: preparation of 10-15g/m2Spun-bonded nonwoven fabric of (a); respectively feeding cellulose fibers and synthetic fibers into a bale opener and a carding machine; placing the spun-bonded non-woven fabric between the cellulose fiber web and the synthetic fiber web, and reinforcing the spun-bonded non-woven fabric into an integral inseparable body by a spunlace machine; then drying and rolling to obtain the non-woven base fabric (carrier layer). Wherein the grammage of the cellulosic fibrous web is set to 20-25g/m2The grammage of the synthetic fiber web is set to 20-25g/m2。
In the preparation method of the present invention, the manufacturing method of the multi-functional dry towel of the present invention is generally divided into two types. The other method is a method for preparing two different essences, which comprises preparing a carrier layer by using a spunlace non-woven fabric processing technology and a spun-bonded non-woven fabric processing technology, and then carrying out liquid feeding. And the liquid feeding step comprises atomizing the essence into fine water drops by using a high-pressure fine water mist spray nozzle and then spraying, wherein the first essence effect liquid is sprayed on the synthetic fiber mesh layer of the carrier layer, drying and rolling are carried out, then the second essence effect liquid is continuously sprayed on the cellulose fiber mesh layer of the carrier layer, and drying and rolling are continuously carried out.
In another manufacturing method, the manufacturing method and the dressing method of the carrier layer are the same as those of the first manufacturing method, except that the method only needs to dress the synthetic fiber web layer of the carrier layer with the first essence efficacy liquid, then dries and winds the synthetic fiber web layer, and does not need to dress the cellulose fiber web layer of the carrier layer with the second essence efficacy liquid, and the synthetic fiber web layer of the carrier layer can be used for absorbing moisture, wiping sweat and the like.
The multifunctional dry towel has the advantages that: two different essences can be added at one time, and the essences do not interfere with each other when used, can exert respective effects to the maximum extent, and can meet the requirements of users with various choices; further advantages are also: only one side of the carrier layer is added with the functional components, the other side is not added, the non-added side is folded inside when the towel is used, and the added side is exposed outside, so that the non-added side can be ensured to be dry when the towel is used, the towel can be used for subsequent treatment, such as wiping and wetting, and the towel plays a role of a dry and wet towel.
It will be appreciated by those skilled in the art that while the product is typically used as a cleansing dry wipe, in practice the application may also be used as a dry wipe requiring both moisture absorption and an effect substance. Such as a power dry towel insole. The synthetic fiber mesh layer of the non-woven fabric base cloth is subjected to essence effect liquid application, the cellulose fiber mesh layer is not subjected to liquid application, and then the insole is processed to be placed inside the shoe. The sweat of feet can be absorbed by most of the cellulose fiber mesh layer, the synthetic fiber mesh layer can absorb a little moisture, and then the synthetic fiber mesh layer can have the effect of essence after being wetted, such as deodorization, bacteriostasis and the like.
The non-woven fabric base fabric of the multifunctional dry towel adopts a water-jet reinforced mode, and is compounded with spun-bonded non-woven fabric, so that the multifunctional dry towel belongs to multifunctional carrier non-woven fabric. The cellulose fiber web layer is a cellulose fiber web because the cellulose fiber has excellent moisture absorption performance, and the synthetic fiber of the synthetic fiber web layer has poor moisture absorption performance, so that two essences with different effects can be applied, and the cellulose fiber web layer with good moisture absorption performance can be used for absorbing moisture. The spunbonded nonwoven fabric is compounded between the cellulose fiber web and the synthetic fiber web and is used for blocking mutual transmission interference of moisture and essence, but the spunbonded nonwoven fabric is breathable.
The multi-functional dry towel of the utility model has different liquid applying mode from the traditional one. Most of the prior liquid applying methods adopt a soaking process or a modified soaking process. The manufacturing process of the utility model adopts a high-pressure water mist nozzle, firstly atomizes the essence into fine water droplet particles, then sprays the water droplet particles on the surface of the non-woven fabric base cloth, and then contacts and absorbs the water droplet particles, so that the effect components of the essence are basically on the surface of the non-woven fabric base cloth, not only waste is avoided, backflow and pollution are very small, but also the mutual interference of the two essences with different effects is very small.
The utility model has the beneficial effects that: the product provided by the utility model belongs to the technical field of life, and is convenient to use and high in playability. Not only satisfies the consumer groups needing dry towels with different effects, but also enables the dry towels with single effect to be used for wiping, and the like, thereby greatly facilitating the life of people. In fact, the product application field provided by the utility model can also be used as a dry towel which needs to absorb moisture and needs an effect substance to act. Such as functional dry towel insoles and the like, can absorb moisture and sweat and can also enable functional substances for deodorization or bacteriostasis to act.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
