Detailed Description
The utility model will be further described with reference to the drawings and specific examples.
Example 1
This embodiment will be described in detail with reference to fig. 1. The water-repellent hydrophilic spunlaced non-woven fabric comprises a water-repellent layer 1, a lipophilic layer 2 and an oil absorption layer 3 which are compounded; the water repellent layer 1 is a water repellent terylene spunlaced non-woven fabric; the lipophilic layer 2 is made of alkyl ethylene polymer fiber or polypropylene fiber; the oil-absorbing layer 3 is made of a long-chain alkyl methacrylate fiber or a cellulose graft copolymer.
Furthermore, fluorine-free waterproof agents are attached to the surfaces of the polyester fibers in the water-repellent polyester spunlaced non-woven fabric. The water absorption of the polyester fiber is poor, and then a fluorine-free waterproof agent is attached to the surface of the polyester fiber, so that the water repellency of the water repellent layer 1 is further improved. The method specifically comprises the steps of dipping the terylene spunlaced non-woven fabric into a solution containing a fluorine-free waterproof agent, and drying the terylene spunlaced non-woven fabric to obtain the water repellent terylene spunlaced non-woven fabric with the waterproof agent attached to the terylene surface to form the water repellent layer 1.
Further, in this embodiment, polypropylene fibers are used for the lipophilic layer 2. The material mainly utilizes the characteristics of hydrophobicity and oleophilicity of the material, can also utilize gaps among polymer molecules and spaces among fibers to realize the oil absorption effect, and has the characteristic of high oil absorption rate.
The oil-absorbing layer 3 is made of a long-chain alkyl methacrylate fiber or a cellulose graft copolymer. The inside of the methacrylic acid long chain alkyl ester fiber is provided with a certain gap, and under the action of lipophilic groups, the methacrylic acid long chain alkyl ester fiber can expand, only swells and is not dissolved, and oil molecules are wrapped by a macromolecular grid structure, so that the oil absorption capacity is strong, the oil retaining capacity is strong, and oil leakage can not happen after oil absorption is carried out under pressure.
The cellulose graft copolymer mainly comprises the steps of grafting cotton fibers by using acrylic acid long-chain ester and crosslinking and polymerizing wood pulp cellulose by using methacrylic acid alkyl ester. Compared with the traditional high oil absorption material prepared from the monomer polymer, the oil absorption rate and the oil absorption rate of the material are obviously improved.
Further, the oil absorption layer 3 is filled with oil absorption particles among the fibers. The oil absorption particles are gel high-efficiency oil absorption materials, monomer molecules with good oil absorption performance are crosslinked to form a three-dimensional net structure, and the three-dimensional net structure is made into particles and placed in the inner part of the oil absorption layer 3 fiber, so that the oil absorption can be further improved.
Further, the oil absorbing particles are dibenzylidene sorbitol, metal soaps or amino acid derivatives. In this example dibenzylidene sorbitol is chosen.
Example two
This embodiment will be described in detail with reference to fig. 2. The difference between the water-repellent hydrophilic spunlaced nonwoven fabric and the first embodiment is that: an expanded graphite layer 4 is arranged between the water repellent layer 1 and the lipophilic layer 2. The expanded graphite is a material compounded by phenolic resin and active carbon. The advantages of the two materials are complementary, so that a new larger 'oil storage pore' can be formed, and the adsorption capacity of the material on organic macromolecular substances such as domestic sewage oil and the like is stronger.
Example III
This embodiment will be described in detail with reference to fig. 3. The difference between the water-repellent hydrophilic spunlaced nonwoven fabric and the second embodiment is that: a reinforcing layer 5 is provided between the water-repellent layer 1 and the expanded graphite layer 4, so that the strength of the entire nonwoven fabric can be further improved.
The reinforcing layer 5 is nylon mesh cloth which has a square shape with a side length of 1-2 cm.
