The beneficial effects of the invention are as follows:
1. the woven fabric easy to treat in three-proofing is prepared, and is different from the traditional fabric treated by directly using the three-proofing finishing agent in that the material of the fabric is subjected to improvement treatment and then subjected to three-proofing finishing, so that the treated fabric not only enhances the initial three-proofing effect, but also can keep a good three-proofing effect even after being washed for many times. In addition, the fabric treated by the three-proofing technology disclosed by the invention is soft in hand feeling, environment-friendly and healthy, and more comfortable to wear.
2. The traditional three-proofing treatment generally aims at that all-cotton or linen fabrics have better effects, and the three-proofing treatment is carried out after the polyester fabrics are improved by a unique method, so that the three-proofing effect of the fabrics is found to be excellent even after multiple times of washing, and the three-proofing effect is an effect which cannot be achieved by common polyester fabrics in the market.
3. The improvement of the fabric material is that the zirconium complex is used for modifying the polyester fiber, so that the composition of the surface layer of the polyester fiber is changed, the surface energy of the fabric is further reduced, the fabric is firmly attached to the fiber or is chemically combined with the fiber, water, oil and stains are effectively prevented from entering the fiber or between the fibers, and the three-prevention effect of the fabric is improved.
4. The invention is initiated from traditional aluminum soap, namely, water-soluble soap solution is firstly used for treating fabric, then aluminum salt is added for treatment, so that aluminum soap is formed and deposited on the fabric, and water and oil repellency of the fabric is improved, but in the traditional mode, the washing fastness is poor, so that the water and oil repellency effect is not ideal. According to the invention, zirconium with better performance is selected to replace aluminum, zirconium ions are easily loaded by treating and activating fibers, and then triazine ligand is combined with the fibers loaded with zirconium ions, so that the generated triazine-zirconium complex is directly coated on the surfaces of the fibers, and the modified fibers are obtained. As the fiber is modified, the inorganic and organic materials on the surface are bonded on the surface of the fiber more stably, and thus, compared with the fiber treated by the traditional direct three-proofing method, the fiber has better three-proofing effect.
5. According to the invention, alkali deweighting treatment is performed on the polyester fiber in the process of modifying the polyester fiber, so that not only is the softness of the fiber enhanced, but also the surface of the fiber is activated in the process, and a favorable condition is provided for loading zirconium ions on the fiber subsequently.
6. The triazine-zirconium complex is loaded on the polyester fiber, and has strong binding capacity of triazine ring and strong stability after forming the complex with zirconium ions. The complex has a certain three-proofing effect, and can be combined with a subsequent three-proofing finishing agent, so that the three-proofing finishing agent is less prone to falling off, and the fabric can still keep a good three-proofing effect after being washed for many times.
