Formula for Fabric Absorption Rate (ML per Gram)
Fabric Absorption Rate = Amount of Liquid Absorbed (ML) ÷ Weight of Fabric (Gram)
Table of Contents
Fabric absorption rate shows how much liquid fabric can hold per gram. It measures the liquid amount absorbed divided by fabric weight in grams. This rate helps textile engineers check fabric quality and performance.
Absorption rate influences comfort, drying time, and dyeing processes. Knowing this rate helps manufacturers select suitable fabrics for different uses.
How to Calculate Fabric Absorption Rate
The formula for fabric absorption rate is:
Fabric Absorption Rate = Amount of Liquid Absorbed (ML) ÷ Weight of Fabric (Gram)
This formula uses two main values. The amount of liquid absorbed, usually in milliliters, and the fabric weight, measured in grams.
Step-by-Step Calculation Process
Step 1: Prepare the Fabric Sample
Cut a fabric piece of known weight. Use a precise scale to weigh the fabric in grams. Record the weight carefully.
Step 2: Measure Liquid Absorption
Dip the fabric sample in liquid (water or dye solution). Let it soak fully for a fixed time. Remove excess liquid by gentle pressing or draining.
Step 3: Record the Liquid Absorbed
Measure the amount of liquid the fabric holds. You can measure by volume difference or by weighing the soaked fabric and subtracting the dry weight.
Step 4: Apply the Formula
Divide the liquid volume absorbed (in milliliters) by the fabric weight (in grams). The result is the absorption rate in ML per gram.
Factors Affecting Fabric Absorption Rate
Fabric absorption depends on several fabric properties and external conditions.
Fabric Material
Cotton absorbs more liquid than synthetic fibers like polyester. Natural fibers generally hold more water due to their structure.
Fabric Thickness and Density
Thicker and denser fabrics absorb more liquid. The yarn twist and weave pattern also influence absorption.
Finishing and Treatments
Chemical finishes can make fabric water-repellent or hydrophilic. Treatments change the absorption rate significantly.
Temperature and Liquid Type
Higher temperature increases absorption. Different liquids (water, dye, chemicals) have different absorption effects.
Practical Uses of Fabric Absorption Rate in the Textile Industry
Textile engineers use the absorption rate to improve fabric quality and process efficiency.
Quality Control
Checking absorption ensures the fabric meets quality standards. It helps detect defects or unwanted treatments.
Dyeing and Printing
Accurate absorption rate helps control dye uptake and uniformity. It reduces wastage and improves color fastness.
Comfort Testing
Absorption affects how fabric feels when worn. High absorption fabric often feels cooler and more comfortable.
