What Does "Initial Value" Mean? Definition and Significance in Textile Finishing
The shrinkage value describes the percentage by which a textile shrinks during its first wash or dry cycle. This value indicates the extent to which the material changes in length and width and is a crucial factor in the planning, production, and finishing of textiles. The shrinkage value plays a particularly important role in textile printing, embroidery, and cutting, as it can affect both fit and print placement.
Arsonists, your creative partner for high-quality textile finishing in Munich, takes shrinkage into account in every production run. This ensures that prints and designs fit perfectly, retain their color, and deliver the desired quality even after multiple washes.
Why is the ink density important in textile printing?
The input quality directly affects the quality of the final product:
- Fit: Clothing may shrink or become tighter after washing.
- Print position: A design may shift or warp if the fabric shrinks unevenly.
- Fabric stability: A high shrinkage rate can cause the garment to lose its shape or become distorted.
- Customer satisfaction: Only textiles with verified shrinkage properties retain their quality over the long term.
Typical break-in values for various materials
The shrinkage values depend heavily on the material composition:
- Cotton: 3–10% (natural fibers shrink the most)
- Polyester: 0–2% (highly dimensionally stable)
- Blended fabric: 2–5% (depending on the cotton content)
- Viscose: 3–8% (sensitive to heat and moisture)
Arsonists uses pre-tested fabrics with known shrinkage characteristics to prevent production errors.
How is the input value determined?
- Pre-wash test: A fabric sample is washed and dried beforehand.
- Measurement: The measurements before and after washing are compared.
- Calculation: Shrinkage rate = [(Original dimension – New dimension) / Original dimension] × 100.
- Evaluation: The calculated value serves as the basis for cutting, print positioning, and production planning.

Tips for working with the input value
- Pre-treatment: Pre-wash fabrics before printing or sewing to minimize shrinkage later on.
- Note the temperature: High temperatures significantly increase the shrinkage rate.
- Choose quality: High-quality fabrics usually have verified shrinkage rates.
- Provide care instructions: Customers should know how to wash textiles to maintain their shape.
Frequently Asked Questions About the Initial Value
Why do fabrics shrink?
Because fibers contract when exposed to moisture, heat, and movement—especially natural fibers.
Is it possible to prevent shrinkage?
It's not completely preventable, but pre-washing and gentle care can help minimize it.
Does the feed value affect print quality?
Yes. An incorrect feed value can cause warped prints or damaged print surfaces.
