As a seasoned supplier of SMS non woven fabric, I understand the importance of proper storage for maintaining the quality and integrity of this versatile material. SMS non woven fabric, composed of Spunbond-Meltblown-Spunbond layers, is widely used in various industries such as medical, hygiene, agriculture, and packaging due to its excellent properties like high strength, good filtration, and barrier performance. In this blog, I'll share some scientific and practical tips on how to store SMS non woven fabric effectively.
1. Storage Environment
The first and most crucial aspect of storing SMS non woven fabric is controlling the storage environment. This fabric is sensitive to factors such as temperature, humidity, light, and air quality.
Temperature
The ideal temperature for storing SMS non woven fabric ranges from 20°C to 25°C (68°F to 77°F). Extreme temperatures can have adverse effects on the fabric. High temperatures may cause the fabric to become brittle or even melt in severe cases, especially if the fabric is exposed to direct heat sources. On the other hand, low temperatures can make the fabric stiff and reduce its flexibility. Therefore, it's essential to store the fabric in a temperature - controlled warehouse. If possible, use a thermostat to monitor and adjust the temperature regularly.
Humidity
Humidity levels should be maintained between 40% and 60%. Excessive humidity can lead to moisture absorption by the fabric, which may cause mold growth, discoloration, and a decrease in the fabric's mechanical properties. To control humidity, dehumidifiers can be installed in the storage area. In areas with high humidity, it's also a good idea to use moisture - absorbing materials such as silica gel packets inside the storage containers.
Light
Direct sunlight and strong artificial light can cause the fabric to fade and degrade over time. The UV rays in sunlight can break down the chemical bonds in the fabric, weakening its structure. Therefore, the storage area should be kept away from windows and direct light sources. If the warehouse has windows, use blinds or curtains to block the sunlight. For long - term storage, it's advisable to store the fabric in opaque containers or wrap it with light - blocking materials.
Air Quality
The storage area should have good ventilation to prevent the accumulation of dust, fumes, and other pollutants. Dust can settle on the fabric surface and affect its cleanliness, especially if the fabric is intended for use in clean environments such as medical applications. Fumes from chemicals or solvents can react with the fabric and cause damage. Install air filters and ventilation systems to ensure a clean and fresh air supply in the storage area.
2. Packaging
Proper packaging is another key factor in storing SMS non woven fabric. The packaging not only protects the fabric from external damage but also helps to maintain the storage environment inside the package.
Inner Packaging
For individual rolls or sheets of SMS non woven fabric, use polyethylene (PE) or polypropylene (PP) bags as inner packaging. These materials are moisture - resistant and can provide a barrier against dust and light. Make sure the bags are sealed tightly to prevent air and moisture from entering. For fabrics with special requirements, such as those used in medical or food - contact applications, use sterilized or food - grade packaging materials.
Outer Packaging
After inner packaging, use cardboard boxes or wooden crates as outer packaging. Cardboard boxes are lightweight and easy to handle, while wooden crates offer more protection against physical damage during transportation and storage. Label the outer packaging clearly with information such as the fabric type, specifications, quantity, and storage instructions. This will help in inventory management and ensure that the fabric is stored and handled correctly.
3. Stacking and Handling
How the SMS non woven fabric is stacked and handled in the storage area also affects its quality.
Stacking
When stacking the fabric rolls or boxes, make sure they are stacked in a stable and organized manner. Avoid over - stacking, as this can cause the bottom layers to be compressed and deformed. For fabric rolls, stack them horizontally on pallets to prevent them from rolling and to distribute the weight evenly. Leave enough space between the stacks for ventilation and easy access.
Handling
During handling, use appropriate equipment such as forklifts, pallet jacks, or conveyors to move the fabric. Avoid dragging or pulling the fabric directly, as this can cause abrasion and damage to the surface. When lifting the fabric rolls, use lifting straps or clamps that are designed for non - woven fabric to prevent tearing.
4. Inventory Management
Effective inventory management is essential for ensuring the quality of stored SMS non woven fabric.
First - In, First - Out (FIFO)
Implement a FIFO system in the storage area. This means that the fabric that is received first should be used or shipped out first. This helps to prevent the fabric from being stored for too long, which can increase the risk of quality deterioration. Keep a detailed inventory record of the fabric, including the date of receipt, quantity, and storage location.
Regular Inspection
Conduct regular inspections of the stored fabric to check for any signs of damage, mold, or other quality issues. Inspect the packaging for any tears or signs of moisture ingress. If any problems are found, take immediate action to address them, such as transferring the fabric to a different storage location or repackaging it.
5. Industry - Specific Considerations
Depending on the intended use of the SMS non woven fabric, there may be additional storage considerations.
Medical and Hygiene Applications
For SMS non woven fabric used in medical and hygiene products such as surgical gowns, masks, and sanitary napkins, strict cleanliness and sterility requirements must be met. The storage area should be a cleanroom with a controlled environment. The fabric should be stored in sealed, sterilized packaging to maintain its sterility until it is used.
Agricultural Applications
In the agricultural sector, SMS non woven fabric is used for products like Banana Fruit Protective Bag Nonwoven and Frost Protection Tree Cover Non Woven Fabric. These fabrics may be exposed to outdoor conditions during use, but during storage, they still need to be protected from moisture and pests. Store them in a dry and pest - free area, and consider using insect - repellent materials in the storage containers.
Packaging Applications
For packaging applications, the appearance and cleanliness of the SMS non woven fabric are important. Fabrics used for packaging Color Non Woven Fabric need to be stored in a way that prevents scratches and discoloration. Use soft - lined storage containers to protect the fabric surface.
In conclusion, proper storage of SMS non woven fabric is crucial for maintaining its quality and performance. By controlling the storage environment, using proper packaging, following correct stacking and handling procedures, implementing effective inventory management, and considering industry - specific requirements, you can ensure that the fabric remains in optimal condition until it is used.
