In the prior art, various bubble towels have the characteristics, but all the bubble towels have the need of improvement, wherein the common defects of refined ingredient migration (forming a hard surface) and incapability of well controlling the liquid feeding amount in the preparation process are that.
Therefore, there is a need to provide a novel bubble towel base material, a liquid-sprayed bubble dry towel and a preparation method thereof.
The invention content is as follows:
the invention aims to provide a novel non-woven fabric capable of being used as a bubble towel base material, a bubble dry towel sprayed with liquid and a preparation method thereof.
In order to achieve the above objects, in one aspect, the present invention provides a non-woven fabric used as a base material of a bubble towel, the non-woven fabric comprising a three-layer structure including a liquid guiding layer, an absorbing layer and a liquid guiding layer in sequence, wherein the effective components of the bubble towel are firmly locked in the non-woven fabric through the liquid guiding layer and the absorbing layer by a liquid adding manner of spraying and atomizing;
the liquid guide layer of the non-woven fabric is formed by mixing hydrophilic fibers and non-hydrophilic fibers, so that the non-woven fabric achieves a soft and hydrophilic effect and achieves good liquid guide performance;
wherein, the absorption layer of the non-woven fabric adopts high hydrophilic fiber, so that the non-woven fabric has good liquid absorption and storage capacity;
wherein, the fibers of the liquid guiding layer, the absorbing layer and the liquid guiding layer are mutually cohered and entangled by a spunlace process to form a whole.
The hydrophilicity of a fiber material is a property of being wetted by moisture on the surface of the fiber material, and is an interface phenomenon, and the essence of the wetting process is a change in the property and energy of a substance interface. When the cohesion between water molecules is smaller than the mutual attraction between the water molecules and the molecules of the fiber material, the fiber material is wetted by water, and the fiber material is hydrophilic and is called hydrophilic fiber material; when the cohesion between water molecules is larger than the attraction between water molecules and the fiber material molecules, the surface of the fiber material cannot be wetted by water, and the fiber material is hydrophobic (or called hydrophobic), and is called as a hydrophobic fiber material.
Contact angle (contact angle) is generally used to measure the hydrophilicity of a fibrous material. At the intersection point of three phases of water (liquid phase), fiber (solid phase) and air (gas phase), an included angle theta formed by a tangent line along the surface of a water drop and a contact surface of the water and the fiber is called a contact angle, namely the contact angle theta refers to an included angle from a solid-liquid interface to a gas-liquid interface through the inside of the liquid at the intersection point of the three phases of the solid, the liquid and the gas.
If θ <90 °, the fiber surface is hydrophilic, i.e., the liquid wets the fiber more easily, and the smaller the angle, the better the wettability, and if θ is 0 °, the fiber is completely wetted; if θ >90 °, the fiber surface is hydrophobic, i.e., the liquid does not easily wet the fiber and easily moves on the surface, and if θ is 180 °, the fiber surface is completely non-wet.
Preferably, in the nonwoven fabric for the pouf base material of the present invention, the hydrophilic fiber used in the liquid conductive layer is a fiber having a contact angle of less than 90 °, the non-hydrophilic fiber used in the liquid conductive layer is a fiber having a contact angle of more than 90 °, and the super-hydrophilic fiber used in the absorbent layer is a fiber having a contact angle of less than 45 °.
In the non-woven fabric used as the base material of the bubble towel, the refined components are stored in the absorption layer by controlling the hydrophilicity of the fibers of different layers, and the combination of the refined components and the absorption layer is firmer relative to the combination of the refined components and the liquid guide layer, so that the bubble towel is not easy to migrate, and the dried bubble towel obtained after drying has soft surface skin feeling. In addition, the metering pump is used for controlling the liquid outlet amount of the effective liquid, so that the basic control of the liquid storage capacity (preparation process) of the effective liquid can be realized, the relatively accurate control of the liquid feeding amount can be realized, and the uniform distribution of the effective components and the control of the foaming capacity during use can also be realized.
In the nonwoven fabric for the base material of the bubble towel according to the present invention, the hydrophilic fiber used in the liquid guiding layer is preferably a natural cellulose fiber because the natural cellulose fiber is green and environmentally friendly and biodegradable on the one hand, and is mild and compatible with the skin on the other hand.
More preferably, the hydrophilic fibers in the liquid-conductive layer are natural cellulose fibers selected from one or more of the group consisting of: viscose, lyocell, bamboo, and modal. The natural cellulose fibers have certain liquid absorption performance, and can play a good role in liquid guiding when being matched with non-hydrophilic fibers.
In the nonwoven fabric for the base material of the bubble towel according to the present invention, the non-hydrophilic fiber used in the liquid guide layer is one or more selected from the group consisting of: polyester fiber, nylon fiber, polypropylene fiber and polyurethane fiber. The chemical fibers can provide better use strength, and the bubble towel is not easy to tear and break when in use.
In the nonwoven fabric for the bubble towel substrate of the present invention, the highly hydrophilic fiber used in the absorbent layer may be wood pulp fiber, bamboo pulp fiber and/or SAF super absorbent fiber.
The wood pulp fiber is a fiber which takes tree wood pulp as a raw material, but is different from a common plant fiber and is a secondary fiber, namely a product separated from the original tree fiber. Generally, wood pulp fibers include: (1) softwood pulp fibers (such as masson pine, larch, red pine, spruce, etc.) and (2) hardwood pulp fibers (such as birch, poplar, basswood, eucalyptus, maple, etc.). Wherein, the hemicellulose component in the wood pulp fiber has loose and amorphous structure and is easy to absorb water and swell quickly.
The bamboo pulp fiber is a regenerated cellulose fiber which is prepared by pulping bamboo chips, then preparing pulp from the pulp and spinning the pulp by a wet method, and the manufacturing and processing process of the bamboo pulp fiber is basically similar to that of common viscose fiber. The research shows that: the cross section of the bamboo pulp fiber is fully distributed with holes, and the bamboo pulp fiber has excellent moisture absorption and air permeability; the longitudinal section of the fiber is provided with a plurality of grooves, which is beneficial to the moisture discharge of the fiber and the saturation among the fibers to form yarns, and has better spinnability. The fabric using the bamboo pulp fiber as the raw material has the advantages of moisture absorption, quick drying, comfort, softness, bright color and the like, and is suitable for textiles which are in direct contact with human bodies, such as home textiles.
Super Absorbent Fibers (SAF) are special function fibers developed following super absorbent resins (SAP). Powder and granular super absorbent resins have excellent water absorbing and retaining capabilities, but when the super absorbent resins are used for manufacturing water absorbing products, difficulties in use and processing are often encountered, and the development of super absorbent fibers is caused by the difficulties. Superabsorbent fibres have been marketed in 1996. At present, there are three major foreign companies which have been used to industrially produce super absorbent fibers, namely Camelot superabsorbent sentswc (trade name "Fibersorb", american ARCO chemical technology), Technical Absorbents (trade name "Oasis", united kingdom kolar and union colloid technology), eastern textile (trade name "Lanseal-F", japan eastern ocean textile and exyland technology), and south china river tide fiber products limited (trade name "white blue", chinese textile science research institute technology).
In order to control the liquid feeding amount more accurately, the ratio of the hydrophilic fiber and the non-hydrophilic fiber in the liquid guide layer may be controlled. Preferably, in the nonwoven fabric for a bubble towel substrate according to the present invention, the hydrophilic fiber is used in a proportion of 50% to 100% and the non-hydrophilic fiber is used in a proportion of 0% to 50% based on the total weight of the liquid guide layer. The specific proportion can be determined according to the production line speed, the components and the performance of the functional liquid and the specific fiber variety.
Preferably, the nonwoven fabric for the base material of the bubble towel of the present invention has a grammage of 40 to 100g/m2。
On the other hand, in order to achieve the above purpose, the invention also provides a bubble dry towel for spraying the liquid, wherein the bubble dry towel adopts the non-woven fabric. Because the essential components are mainly stored in the absorption layer, the dried liquid guide layer still presents soft skin feeling.
Preferably, in the bubble dry towel of the present invention, the nonwoven fabric used as the base material of the bubble towel has an upper liquid content of 30 to 300g/m in a wet weight state2In the range of, for example, 30 to 150g/m2In the meantime.
In another aspect, to achieve the above objects, the present invention further provides a method for preparing the bubble dry towel, which comprises the following steps:
(1) forming a liquid guiding layer: opening, carding and lapping selected hydrophilic fibers and/or non-hydrophilic fibers into a thin fiber net by a carding machine to form a nascent fiber net;
(2) forming an absorption layer: carding the selected high-hydrophilicity fibers into a thin fiber web by a carding machine to form a nascent fiber web; or wood pulp boards (short fibers) and/or bamboo pulp boards (short fibers) are mechanically scattered and laid by air flow to form a nascent fiber web;
(3) and (3) water needling to form a whole: superposing the nascent fiber web obtained in the steps (1) and (2) from top to bottom according to a liquid guiding layer, an absorption layer and the liquid guiding layer, and rebounding on the surface of the supporting net curtain by utilizing fine high-pressure water flow and fine high-pressure water flow to form a puncture effect, so that the fibers of all layers are mutually cohered and entangled to form a whole with certain strength;
(4) drying the whole obtained in the step (3) by a drying device to obtain non-woven fabric used as a base material of the bubble towel;
(5) controlling the liquid output amount of the efficacy liquid by using a metering pump, spraying the efficacy liquid onto the non-woven fabric obtained in the step (4) by using an atomizing spray head, and introducing the efficacy liquid into an absorption layer of the non-woven fabric through a diversion layer;
(6) and (5) drying and cutting the non-woven fabric sprayed with the functional liquid obtained in the step (5) to obtain the bubble dry towel.
Preferably, in the step (1) above, if the liquid guide layer includes both hydrophilic fibers and non-hydrophilic fibers, a blending process is further included.
Preferably, in the above step (3), in the hydroentangling process for combining the liquid-conductive layer and the absorbent layer, the water pressure (gauge pressure) is 40bar to 75 bar; in the step (4), the drying temperature for drying the whole body obtained in the step (3) is 120-150 ℃, and the gram weight of the non-woven fabric obtained after drying is 40-100g/m2。
