In nonwoven production manufacture field, " one kind improves polyethylene nonwoven to Chinese patent (CN201410522953.4)
The corrosive liquid that hydrophilic method " is formed using ferric trichloride and sulfuric acid carries out hydrophilic modifying to polyethylene nonwoven, has work
Skill is simple and convenient to operate, cost is low, is easily achieved the advantages that scale.Also, the poly- second for being modified to obtain using the inventive method
Alkene non-woven fabrics, hydrophilicity is strong, resistance to protein contamination, and mechanical strength is high, service life length, can realize solid-liquid as filtering material
Separation, reaches filtering accuracy requirement；" a kind of high water absorption silk non-woven fabric produces work to Chinese patent (CN201310525959.2)
Silk fiber or silk water non-woven fabrics are sprayed, soaked or padded by skill ", greatly improve the water imbibition of silk fiber, from
And the non-woven fabrics is applied to beauty treatment fields or is cured auxiliary material field has the premise of large-scale popularization, while available for production such as face
Film patch, bandage and medical auxiliary material etc., so that product has health care, moisturizing and the good technique effect of soft comfortable degree；The U.S.
Patent (US 6720070) " Hydrophilic polyester fiber and hydrophilic nonwoven fabric
The water-based hybrid dispersions of using the same and their production " contain by polyester components and polyether component group
Into polyester-polyether block copolymer, its stability be less than 35 DEG C, when the dispersity of polyester-polyether block copolymer passes through
When being heated to 35 DEG C and being broken, polyester fiber, non-woven fabrics are provided with hydrophily.So far, yet there are no polypropylene non-woven
Cloth prepares the appearance of the related process of hydrophilic non-woven by vacuum plasma treatment technology.
The present invention carries out surface modification using by vacuum plasma treatment to polypropylene non-woven fabric, is had
The polypropylene non-woven fabric of hydrophilic sexual function.Preparation method of the present invention is simple and easy, and vacuum plasma is modifies to not only increase nothing
The hydrophily and adhesiveness of cloth are spun, while improves the mechanical properties such as its tensile force, tensile strength, is had important practical significance.
The content of the invention
