Hydrophilicity (water absorption): </p
Water dripping method: Use a rope or rubber band to fix the fabric to the mouth of the beaker. Make the tip of the buret about 1.0±0.1cm away from the cloth and drop a drop of distilled or deionized water onto the surface of the fabric. Use a stopwatch to record the time required for the mirror reflection of the water droplet to disappear. time �</p
毛效法：沿布的经向或纬向取2.5cm×20cm的布条，测试5min或30min的毛效。

Quick drying test: </p
简易法：在待测试布上滴上4滴清水，记录水份在室温下蒸发所需的时间。
Precise method: Use a rubber band to fix the fabric to the mouth of the beaker, put it into a constant-temperature oven with a weighing device, and keep it warm under drying conditions of 3°C. After reaching constant weight, use a pipette to measure a certain amount of water (such as 0.2mL) is dropped on the cloth, ensuring that the area where the water spreads is smaller than the area of the beaker mouth, continue drying in a constant temperature oven, weigh every 5 minutes, and record the time required to reach constant weight (weight before dripping) �</p
