As an important protective equipment in industries such as medicine, electronics, and food, the maintenance and upkeep of clean and sterile clothing are directly related to maintaining a clean environment and ensuring product quality and safety. The following is a complete maintenance method for clean and sterile obedience from cleaning to storage.
1、 Basic maintenance principles
The maintenance and upkeep of clean and sterile clothing should follow the following basic principles:
1. Classification management: Clean and store according to the cleanliness level of the usage area (such as A/B/C/D level).
2. Professional equipment: Use industrial grade dust-free washing machines and drying equipment, equipped with high-efficiency filters.
3. Special detergent: Choose a neutral pH non-ionic surfactant to avoid damaging the fabric.
4. Strict process: Establish standardized cleaning, disinfection, drying, packaging, and storage processes.
5. Record traceability: Number each batch of clean clothes and record cleaning and disinfection information.
2、 Professional Process for Cleaning and Disinfection
1. Preparation before cleaning
•Collect dirty and clean clothes by cleanliness level classification.
•Pre treat obvious stains (enzyme wash or hand scrub).
•Check the integrity of the clothing, and dispose of severely damaged items.
2. Professional cleaning steps
•Main washing stage: Use specialized detergent and control the water temperature at 40-50 ℃.
•Rinse stage: Rinse at least 3 times, and finally use deionized water (resistivity ≥ 10 megaohms/cm).
•Disinfection treatment: Infectious fabrics need to be soaked in chlorine containing disinfectant for 30 minutes or treated at 75 ℃ for 30 minutes.
•Neutralization treatment: Ensure that the pH value after washing is close to neutral to avoid skin irritation.
3. Drying and tidying
•Use professional drying equipment with high-efficiency filters.
•The drying temperature should not exceed 60 ℃ to avoid fabric damage.
•Folding and packaging in a clean environment.
3、 Special maintenance for different materials
1. Polyester fiber/conductive fiber fabric
•Avoid using bleach and strong acid and alkali detergents.
•The washing water temperature should not exceed 50 ℃ to prevent the degradation of conductive fiber properties.
•Do not soak for a long time (recommended not to exceed 30 minutes).
•Avoid high-temperature ironing to prevent fabric deformation.
2. Composite functional fabric (anti-static+dustproof)
•Do not use fabric softeners as they may clog the fiber gaps.
•Avoid friction with rough objects to prevent damage to the surface coating.
•Keep dry during storage to prevent mold growth.
3. Specially treated fabrics (such as fluoropolyester)
•Suggest dry cleaning, washing with water will reduce chemical inertness.
•Do not use chlorine containing detergents.
•Avoid folding and creasing during storage.
4、 Storage and usage precautions
1. Storage environment requirements
•Temperature: 18-24 ℃
•Humidity: 35-70%
•Avoid light, dust, and have good ventilation
•Ground clearance ≥ 20cm, wall clearance ≥ 5cm, roof clearance ≥ 50cm
2. Pre use inspection
•Check the integrity of the packaging and sterilization instructions.
•Confirm to use within the validity period.
•Check for signs of damage, stains, or performance degradation.
3. Usage standards
•Avoid contact with the ground and other sources of pollution when putting on or taking off.
•Do not mix with non clean area items.
•Immediately put it into a dedicated recycling container after use.
5、 Service life and replacement standards
Clean and sterile clothing needs to be regularly evaluated for its performance status, and should be replaced in a timely manner when the following situations occur:
1. Physical damage: obvious wear, tear, or suture opening.
2. Functional degradation: The anti-static performance test failed (surface resistance>10 ^ 9 Ω).
3. Cleaning frequency: It is generally recommended to clean 50-100 times before replacement (depending on the material).
4. Pollution risk: inability to thoroughly disinfect after exposure to high-risk pollutants.
5. Appearance changes: obvious discoloration, hardening, or fiber detachment.
It is recommended to establish a usage record for each clean suit, recording the frequency of cleaning, performance testing results, and replacement time, to achieve full lifecycle management.
Through the maintenance methods of the above system, it can be ensured that clean and sterile clothing always maintains the best protective performance, providing reliable protection for a clean environment. Different industries can develop more detailed maintenance procedures based on their own characteristics, but the core principles should remain consistent.
