Wet Pickup Percentage

Saturation Indicator

Liquid measurement calculates the weight of liquor retained by a textile after it exits the immersion tank and squeeze rollers. Expressed as a ratio of the added weight to the original dry weight, wet pickup percentage dictates the amount of chemical that stays on the cloth. Accurate readings here allow mills to predict raw material costs and ensure that the correct dose of dye enters the dryer.

Process Influence

Pressure from the padding rollers determines how much fluid is pushed deep into the core. Variation in wet pickup percentage across the width of the fabric causes side-to-center shading in the finished product. To lower this risk, engineers calibrate the rubber hardiness and hydraulic pressure of the squeeze system daily.

Formula Logic

Calculation involves weighing a one metre piece of fabric before and after it passes the nip point. Adjusting the wet pickup percentage allows for fine control of chemical concentration without changing the bath composition. Fabric speed also influences this number because faster cycles leave less time for fluid to be squeezed out.

Dryer Load

Higher levels of liquid carry-over require more energy for complete evaporation in the oven. Monitoring the wet pickup percentage is the primary check for consistent finishing quality.
