What Is the Humidity Standard for the Garment Industry?

The humidity standard for the garment industry varies depending on the type of fabric and the specific processes involved. A dehumidifier is essential in a garment factory to maintain optimal humidity levels, prevent mold, protect fabrics, and improve overall production efficiency.

1. Manufacturing and Weaving Processes

50-65% Relative Humidity (RH) is ideal for weaving and textile production.

The optimal humidity level will help prevent static electricity and ensures smoother fiber processing.

Maintaining the humidity level in this range can reduce yarn breakage and improves fabric quality.

2. Cutting and Sewing Departments

45-55% RH is optimal for precise cutting and stitching.

The optimal humidity level will prevent fabric shrinkage and distortion.

Use a smart dehumidifier with pump can ensures better alignment of patterns and seams.

3. Storage and Warehousing

50-60% RH is recommended for storing garments.

Applying an industrial dehumidifier can prevent mold, mildew, and fabric deterioration.

Maintaining the optimal RH helps protect fabric elasticity and prevents unwanted wrinkles.

4. Showrooms and Retail Environments

40-50% RH is common in display areas.

Ensures garments remain fresh without excessive moisture buildup.

Provides a comfortable shopping experience for customers.

5. Special Considerations for Different Fabrics

Cotton & Wool: Require higher humidity (55-65% RH) to prevent brittleness.

Synthetic Fabrics (Polyester, Nylon): Work best at 45-55% RH to reduce static electricity.

Silk: Requires stable 50-60% RH to maintain texture and prevent damage.
