Description

technical field

[0001] The invention relates to the field of fabric waterproof and antifouling, in particular to a fabric fluorine-free water-repellent spray and a preparation method thereof. Background technique

[0002] When the new jacket and trousers are attacked by rainwater, the rainwater will form water droplets on the surface of the clothing and roll down naturally, preventing moisture from penetrating into the fabric. This is DWR (Waterproof Treatment of Jacket). The outer fabric of outdoor fabrics will be treated with DWR to form a non-hydrophilic protective coating to prevent the outer fabric from being soaked and penetrated by water, so as to ensure that water vapor will not adhere to the fabric and will not form a water film, making it reach Surface waterproof effect. However, during the long-term wearing and washing process of the DWR coating, due to the influence of external forces, the adhesive bond will slowly decay until it breaks, the coating active agent...
