Description
Technical Field
The invention belongs to the technical field of high polymer materials, relates to a hydrophilic finishing agent and a preparation method thereof, and particularly relates to a durable hydrophilic finishing agent for non-woven fabrics and a preparation method thereof.
Background
Currently, the nonwoven industry is being thriving, and nonwoven fabrics have played an increasingly important role in daily life, and have been widely used in the fields of medical materials, filter materials, clothing materials, decorative materials, wiping materials for hygienic products, geotechnics, and construction. However, the requirements for nonwoven fabrics used in different fields or applications are not the same. In some specialty products, such as nonwoven fabrics used in water filtration products, hygiene products, wiping products, and the like, good hydrophilicity is often required.
The non-woven fabric composed of polypropylene or polyester has the advantages of stable raw material source, high strength, wear resistance, good chemical stability, low cost and the like, and occupies a larger share in the non-woven fabric. However, polypropylene or polyester has high crystallinity, compact molecular structure and no hydrophilic group, so that polypropylene or polyester non-woven fabric composed of the polypropylene or polyester non-woven fabric has poor hydrophilicity, water drops are not easy to spread and penetrate on the fabric surface, and the application of the polypropylene or polyester non-woven fabric in the fields of water filtration, sanitary products, wiping cloth and the like is severely limited.
At present, the hydrophobic polypropylene/polyester non-woven fabric is generally subjected to hydrophilic treatment by means of protofilament modification, surface grafting modification, plasma treatment, hydrophilic after-treatment and the like. In contrast, the post-finishing method for obtaining hydrophilicity by applying a hydrophilic finishing agent on the surface of the nonwoven fabric and then attaching the hydrophilic agent to the fibers through a hot baking treatment has the advantages of simple operation, low requirements on instruments and equipment, low cost and the like, and has attracted extensive attention of researchers. In the hydrophilic finishing method, the hydrophilic polypropylene/polyester nonwoven fabric is obtained most mature and convenient by applying a hydrophilic surfactant, however, the method is generally poor in washing fastness, cannot maintain the hydrophilic durability of the nonwoven fabric, is generally mainly applied to some disposable wiping products such as wet tissues, wiping cloths and the like, and shows obvious disadvantages in the aspect of seeking for the hydrophilic nonwoven product with good durability. The current society has pursued environmental protection and economy, how to reduce the consumption of energy and resources, and how to reduce the utilization rate of non-degradable disposable hydrophilic non-woven fabric products has become a research hotspot, and the development of durable hydrophilic finishing agents for non-woven fabrics is becoming urgent.
