4results about How to "Improve quick-dry performance" patented technology

This invention relates to high-performance fibers and products, and composite materials, particularly to a water-absorbing and quick-drying agent, a water-absorbing and quick-drying treatment method, water-absorbing and quick-drying fibers, and water-absorbing and quick-drying textiles. The water-absorbing and quick-drying agent of this invention is used to treat fibers or fabrics and includes: a solvent; an alcohol substance with a volume content of 1-300 g / L; and an etherified vinyl urea resin with a volume content of 1-150 g / L. The pure cotton moisture-absorbing and quick-drying fibers or fabrics produced by this invention improve the moisture absorption and quick-drying properties of pure cotton products while retaining the skin-friendly and soft characteristics of cotton fibers, thus developing a high-performance moisture-absorbing and quick-drying pure cotton fabric suitable for sportswear.

The present application relates to the technical field of curing glue paint, in particular to a preparation method of water-based single-component plastic paint. The water-based single-component plastic paint prepared by the present application overcomes the problems of poor environmental protection and difficult balance of comprehensive performance of paint film. The water-based single-component plastic paint is prepared by optimizing the preparation method and raw material system; the alicyclic isocyanate is selected and step-by-step reaction is combined with ring-opening epoxy resin, quercetin and disulfide to form a dense coating, so as to improve corrosion resistance and adhesion; hydrolyzed KH560 and polyurethane-polyurea composite system are used to introduce fluorine-containing monomers, so as to enhance water resistance and low-temperature stability; a three-dimensional network is constructed by free radical copolymerization, triethylamine is added to inhibit polymerization, and the feeding and post-ripening steps are optimized to balance the hardness, drying speed and surface state after cooking. The water-based single-component plastic paint of the present application is suitable for various plastic substrates such as automobile interior and exterior trim and 3C products, and has significant advantages in protection performance and construction adaptability.

This invention discloses a fast-drying waterborne polyurethane resin, its preparation method, and its application. By weight, it comprises the following components: 30-40 parts of self-made polyester polyol, 30-50 parts of polyether polyol, 2-5 parts of chain extender, 1-3 parts of hydrophilic monomer, 1-3 parts of trimethylolpropane, 40-60 parts of isocyanate, 1.1-1.5 parts of neutralizer, and 50-80 parts of solvent. This fast-drying waterborne polyurethane resin utilizes self-made branched polyester and polyether to construct flexible segments that combine rigidity and flexibility. Low hydrophilic monomer content enables self-emulsification and ensures water resistance. Trimethylolpropane and self-made polyester polyol form a double crosslinking network with built-in branching points. Isocyanate compounding balances hardness and pot life. The high R-value design allows residual NCO to naturally generate urea bonds during emulsification, compensating for the emulsification difficulties caused by low hydrophilicity. Ultimately, it achieves a balance between fast drying and high water resistance without the addition of external drying agents or amine-based chain extension. It combines fast drying, high water resistance, and excellent mechanical properties. The process is simple and low-cost, making it highly valuable for industrial promotion.

The invention belongs to the technical field of shirt preparation, and discloses a moisture-absorbing, quick-drying and solution-drop-free integrated shirt and a manufacturing method thereof.The moisture-absorbing, quick-drying and solution-drop-free integrated shirt comprises a shirt body, the shirt body comprises a shirt fabric for tailoring and forming the shirt, and the shirt fabric comprises an inner moisture-absorbing layer, a middle humidity adjusting layer and an outer breathable layer. The quick-drying agent is stably and long-acting filled in the fabric of the shirt, sweat molecules are quickly diffused from the inside of the fabric to the outside, evaporation is accelerated, the quick-drying performance of the shirt is improved, sweat is quickly evaporated, the shirt is kept dry and comfortable, the time of the sweat staying on the surface of the fabric is shortened, and the shirt is more comfortable. Meanwhile, in cooperation with the combined arrangement of the inner moisture absorption layer, the middle moisture adjusting layer and the outer breathable layer, on one hand, the moisture absorption and quick drying effects are achieved, the wearing comfort is improved, on the other hand, the problem of solution drops is solved, solution drops are prevented from being formed, the use risk in special occasions is reduced, the comprehensive wearing attractiveness is improved, and the shirt is good in comprehensive wearing experience, high in safety and good in use effect.
