The Importance of Humidity Control in the Garment Industry

Air humidity plays a pivotal role in the garment industry. Both excessively high and low humidity can cause significant negative impacts:

• For raw materials (fabric, yarn, thread, accessories):
  • High humidity: Creates conditions for mold and bacteria growth, especially on natural fibers (cotton, linen, silk), causing unpleasant odors, discoloration (yellowing, black spots), and reducing fiber strength. Fabric fibers absorb moisture, swelling, leading to size and weight discrepancies, affecting cutting and sewing accuracy. Dyes can oxidize or hydrolyze, causing color fading and bleeding. Metal accessories can rust, and leather/imitation leather can mold and peel.
  • Low humidity: Makes fibers brittle and easily broken, reducing fabric strength. Increases static electricity, causing fabric to attract dust, layers of fabric to stick together (making cutting difficult), and causing discomfort for workers.
• For the production process:
  • Cutting stage: High humidity makes fabric sticky and difficult to lay flat. Low humidity causes static electricity, making fabric layers cling together, affecting accuracy.
  • Sewing stage: Moist sewing threads easily break. Sewing machine needles easily rust. Modern electronic machinery can be affected by high humidity.
  • Finishing stage (ironing, pressing glue): Humidity affects glue pressing quality and adhesion. Ironing is more difficult if the fabric is too moist or too dry.
  • Printing, embroidery: Humidity affects ink adhesion and embroidery quality.
• For finished products: Easily subject to mold, discoloration, and unpleasant odors when stored or transported in humid environments. Leads to reduced product quality and lifespan, causing loss of brand reputation with customers.
• For machinery and equipment: Metal components are prone to corrosion and rust in high humidity environments, reducing lifespan and accuracy. Electronic components can malfunction and be damaged.
• For the working environment: Humid environments affect worker health and productivity.
• Increased costs: Increased costs for handling defective products and machinery maintenance.

The ideal humidity level for the garment industry typically ranges from 50% - 65% RH (Relative Humidity).

Humidity Control Solutions with Industrial Dehumidifiers

To thoroughly address the above issues, implementing humidity control solutions is crucial. Industrial dehumidifiers are among the most effective and popular solutions, especially when looking for dehumidifiers for the garment industry.

Operating principle: Popular industrial dehumidifiers operate based on the condensation principle. Humid air is drawn in, passes through a cooling coil, where water vapor condenses into water and flows out. Drier air is then blown back into the environment. Some machines use desiccant rotor technology for applications requiring very low humidity or operating at low temperatures.

Benefits of industrial dehumidifiers in the garment industry:

• Protect raw materials and finished products from mold and bacteria.
• Enhance product quality by ensuring the physical and mechanical properties of fabrics, and precision in cutting and sewing.
• Optimize production processes, minimizing issues like sticky fabrics, static electricity, and thread breakage.
• Protect machinery and equipment from rust and corrosion, extending their lifespan.
• Improve the working environment, creating a dry and airy space, enhancing worker health and productivity.
• Save costs by reducing defective product losses, maintenance costs, and energy compared to using air conditioners for drying.

Frequently Asked Questions When Choosing Dehumidifiers for the Garment Industry

How does air humidity affect the garment industry?

Humidity in the garment industry significantly impacts every stage from raw materials to finished products and the production process. High humidity causes fabric fibers to absorb moisture, swelling, leading to size and weight discrepancies, affecting cutting and sewing accuracy. It can also cause dye fading, color bleeding, metal accessories to rust, and leather/imitation leather to mold and peel. Conversely, low humidity makes fibers brittle and easily broken, reducing fabric strength and increasing static electricity, which makes fabric cling to dust, layers of fabric stick together (making cutting difficult), and causes discomfort for workers. During the cutting process, high humidity makes fabric sticky and hard to lay flat; low humidity causes static electricity. When sewing, high humidity reduces thread strength, causes thread breakage, makes sewing machine needles rust, and affects modern electronic machinery.

How does humidity affect machinery and equipment in the garment industry?

High humidity is the main cause of corrosion and rust in metal components on machinery such as cutting machines, sewing machines, overlock machines, and heat presses, reducing the lifespan and accuracy of the equipment. Additionally, high humidity can cause flickering and damage to circuit boards and electronic components in modern machinery.

What are common problems caused by high humidity in the garment industry?

High humidity leads to many common problems such as moldy, discolored, and odorous fabrics and finished products; rotten and easily broken sewing threads. Machinery and equipment degrade quickly and frequently break down. Humid working environments negatively affect worker health and productivity. All these issues lead to increased costs for handling defective products and machinery maintenance.

What is the recommended ideal humidity level for the garment industry?

The ideal humidity level for the garment industry typically ranges from 50% - 65% RH (Relative Humidity). Maintaining humidity within this range helps ensure the quality of raw materials and finished products, optimize production processes, and protect machinery and equipment.

What are the most effective humidity control solutions for the garment industry?

To address humidity issues, implementing humidity control solutions is essential. One of the most effective and common solutions today is the use of industrial dehumidifiers. Additionally, maintaining appropriate humidity also helps reduce static electricity, which is particularly important for insulating materials.

How does an industrial dehumidifier work and what are its benefits for the garment industry?

The most common industrial dehumidifier operates based on the condensation principle: Humid air is drawn into the machine, passes through a cooling coil where water vapor condenses into water. Drier air is then blown back into the environment. Some machines use Rotor dehumidifier technology for applications requiring very low humidity or operating at low temperatures. The benefits of industrial dehumidifiers in the garment industry include: protecting raw materials and finished products from mold and bacteria; enhancing product quality by maintaining the physical and mechanical properties of fabrics and precision in production; optimizing production processes by reducing issues like sticky fabrics, static electricity, and thread breakage; protecting machinery and equipment from rust and corrosion; improving the working environment for workers; and saving costs by reducing defective products and maintenance expenses.

How do fabric material components affect fabric humidity?

Research shows that the blending ratio of cotton and polyester significantly affects fabric humidity. The higher the cotton content in the fiber and fabric, the higher the fabric's humidity, and vice versa. This provides a scientific basis for selecting appropriate fabric materials, especially for products like workwear, where fabric humidity directly impacts user comfort.

Should Heat-Pump dryers be integrated into garment storage warehouse solutions?

Heat-Pump dryers (such as DeAir.RE-H) can be integrated as a supplementary solution for storage warehouses, especially when there is a need to dry products. The advantage is the ability for specialized drying to quickly dry slightly damp batches or products, eliminate residual moisture, handle unexpected moisture issues, and save energy compared to traditional drying. Heat-Pump dryers dry at lower temperatures, helping to protect fabric and accessory quality. However, the disadvantage is a higher initial investment cost than specialized dehumidifiers; their primary purpose is product drying, not general air humidity control in the most energy-optimal way, and they require suitable installation space for the drying process. Integration consultation should be based on the specific product drying needs of the business.
