SHOES FACTORY MOLD PREVENTION MEASURES
We expect all vendors/agents/manufacturers to be guided by the following measures as well as any extra appropriate mold, mildew, fungus preventive measures at all times, especially during the defined mold/mildew rainy season. These guidelines should help reduce any incidents of mold.
The mold prevention measures have been integrated in the form of an updated mold prevention check list which will be utilized along with Integri’s factory evaluation audit to ensure the strict implementation by factories.
We have specified the most important and obligatory measures which are defined as mandatory checking items. In case they are not carried out by factories, it will result in automatic failure on Integri’s factory evaluation audit.
Any failure to sustain ongoing, robust mold management practices and associated disciplines that leads to complaints of mold or mildew of product in the supply chain or at stores will lead to an assessment of chargeback’s for defective goods.
Ensure that roofs and walls (including windows & doors) do not leak.
Twice a year, all working and storage areas, including walls, floors, ceilings, fans, vents, windows and equipment (exterior and interior) must be sanitized with ASD-PW mildew antibacterial agent. A thorough cleaning is also required after any factory flooding.
Any discolored walls should be bleached and repainted.
Recommend checking the moisture content of incoming materials with ASDCL-001 moisture meter, especially anything that is textile, coated textile, or leather.
All raw materials, components, accessories, shoes must always be put on plastic pallets at a minimum of 12 cm above the floor and at least 1.5 meters away from windows, covered and sealed against dust exposure.
Old stock materials and actual production materials must be separated for storage, including semi-finished and completely finished products.
Production areas must install adequate, functioning de-humidifiers, fans for good air circulation and ventilation. In order to maintain a relative humidity of 50-60%, a humidity gauge and thermometer should be installed so temperature and humidity can be monitored consistently recorded daily.
Storages rooms must have proper roofs for protection during rainy
weather. Ensure factory roofs and walls do not leak.
Cover or seal materials to prevent dust exposure.
All storage areas must have internal forced air circulation (fans). Keep windows closed. Do not allow stagnant air.
All materials must be cycled on a “first in, first out” basis.
All raw materials inventory must be consumed and replenished timely so that goods do not remain in storage for extended periods.
MATERIALS LAMINATION PROCESS
ASD-SX glue anti-mold agent to be added to lamination glue or latex before the upper lamination process, and all lamination materials to be cut within two days.
Post a chart in laminating room showing the correct time & temperature needed to laminate different combinations of materials.
Cooling fans to be installed in the upper lamination machine to prevent uppers from absorbing moisture after lamination.
Clean production and packing area floors, conveyors & packing surfaces daily with ASD-PW mildew antibacterial agent, and then wipe dry with clean cloths.
Spray all floors and wall corners monthly with ASD-PW mildew antibacterial agent.
Factories should install adequate, functioning fans for good air circulation and ventilation.
Cut pieces should be stored in breathable plastic bags prior to stitching. Stitching must commence 1-2 days after cutting.
Stitched uppers should be run through a dryer before being placed into breathable plastic bags prior to lasting.
It is critical to follow the drying and bagging instructions above for uppers stitched in outside stitching rooms as well as any other subcontracted components / semi-products because of additional transit time to the factory. Uppers from outside stitching rooms and any other subcontracted components / semi-products should be inspected and the moisture content checked with ASDCL-001 moisture meter.
All shoes, boxes, lids, should go through a hot air drying tunnel as the last step of production, just before closing the boxes. For most shoes, heat at a minimum of 70 degrees centigrade, for an absolute minimum of 3 minutes time being desirable. Depending on the type of shoe, a lower temperature may be needed to preserve shape and adhesion.
All factories must install properly functioning UV lights at the end of each production line. All semi-finished products or finished products must be subjected to appropriate heat and UV treatment to ensure they are completely dry before being stored.
Ensure all shoes are subjected to a sufficient period of heat treatment during production, especially in humid and rainy weather.
Packing line workers must wear clean uniforms or aprons and should not wear any gloves made of cotton. They should wash their hands with soap & water to remove grease & oil before returning to the line.
5.03 真正的和有效的Orston防霉干燥劑作為最后的包裝工序,必須在鞋子經過烘箱處理后, 再放置在盒子內的指定位置。
As the final packaging step, genuine and non-expired Orston mildew proof desiccant must be placed in the inside of boxes in the prescribed location after shoes have passed through the oven.
All products are to be packed into cases the same day as produced.
Keep shipping cartons dry. Do not use damaged or wet cartons.
Pack shoes into shipping cartons as soon as possible after being removed from the dryer and shoe box lids are closed.
Re-inspect shoes not shipped within 7 days of the vendor’s/agent’s final warehouse audit to ensure that the shipping condition of the order is mold free.
Before loading of containers, factories to check to ensure containers are not wet and do not leak.
If an open CFS delivery truck is used, then completely cover canvas top with a second heavy plastic tarp.
Take extra precaution to ensure shipping cartons are not wet or damaged during transportation.
Vendor/agent must monitor the loading of containers and take photos for record purposes.
