There Should Be A Clever Way To Deal With Moldy Footwear Products.

Wet spring is coming, how should products be dampproof?

Let's first understand the underlying cause of moldy footwear.

1. In fact, mold is a simple single cell microorganism, but its propagation speed is fast and its harm is relatively large.

Common microbes are: * bacteria, fungi, viruses, algae.

Two. How do bacteria grow?

Any bacterial growth requires four basic conditions:

* nutrition sources (soil food, leather sweat, etc.)

* suitable temperature

* suitable humidity

An attached surface (particles in the air, skin, leather, surface of the fabric)

Molds especially like dark, moist environment and leather. The surface of the fiber is concave and convex.

Three. What is the danger of bacterial growth?

* bad smell, bad smell.

* stains, stains.

* product deterioration, mold rot, damage.

* endangering our health

Seriously affect the appearance and quality of products

Four. Why are footwear products moldy in recent years?

1. new materials, heavy oil containing materials, have become hotbeds for oil, fungi and mold.

2. the European Union strictly restricts the use of pesticides and preservatives, so that a large number of bacteria and fungi can survive.

3. environmentally friendly water dehydration is widely used to provide nutrition and food for mold propagation.

4. sea pportation, temperature and temperature vary greatly, increasing the risk of dampness and mildew.

Five. Commonly used methods of mildew prevention:

* heating sterilization

* hypoxic preservation

* low temperature mildew proof method

* ultraviolet irradiation sterilization.

Six. Handling packaging is one of the most effective measures at present.

Including: 1. mould proofing of wrapping paper

2. anti mildew treatment of packaging bags

3. package handling

Seven. Matters needing special attention in the production of footwear products.

According to the production process of the general shoes and the production process of the factory, combined with the characteristics of the good anti mildew series products, we sum up our practical experience for many years, draw lessons from the successful practices of WAL-MART (WAL-MART) in coordinating the factory's quality management measures, and suggest that the following methods should be adopted to control the growth of the mould effectively and effectively, so as to ensure that the shoes are not mildew in the production, storage and pportation process, and completely solve the harm of the moldy shoes, and let the guests have no worries.

First, the newly selected fabrics (especially crazy horse oil skin, discolourant oil, oil grind, leather, leather, braided, etc.) with long fiber and heavier fat are produced before the batch production. The samples are tested for microbiological tests. The contents of animal fat, vegetable fat, mineral lipids, starch, saturated and unsaturated fatty acids and microorganisms are determined to determine whether special treatment is needed.

Two, the heel (especially cladding skin and heel) can not exceed 9% of its humidity. If you use water-based adhesive, you should add a 3%-5% mildew inhibitor in the water-based adhesive or hardening agent to prevent it from dampening after being waxed. The shoelace must be completely dry and its humidity should not exceed 8%. Spray the mould inhibitor before drying it and completely dry it.

Three, needle line and Mark line (especially cotton and wax line) should be properly mildew proof.

Four. The steam in hot glue is not easy to dry completely. It is recommended that the bags should be completely cooled before they are completely dried. The moisture content should not exceed 8%. It is suggested that 3%-5% antiseptic should be added to the water adhesive glue. When the freezer is working, the condition of frosting is easy to stagnant water vapor. It is recommended that the inner wall of the freezer be regularly cleaned with mould inhibitor.

Five, the shoeshine shoes suggest that mildew cleaning agents or 3%-5% detergent should be added to the cleaning agent. Shoe polish shoes suggest that 5% of mildew inhibitor is added to shoe polish, and there is also a significant preventive effect.

Six, the amount of spray mildew inhibitor on the upper, with 1 grams per shoe as the standard.

For leather with large humidity, long fiber and high fat, the dosage should be 2 grams per square foot.

Don't forget the location of shoelaces, shoes and heels.

The boots with wool should be properly sprayed.

Seven, the factory's air compressor needs to discharge water regularly or add air filters, otherwise it will easily discharge water accumulated in the trachea when it first sprays, causing moldy.

Please do not adjust the vacuum freezer to critical frosting, so as to avoid stagnant water. It is difficult to dry.

Eight, pure white shoes or sheepskin, gold lacquer sheepskin, glossy oil skin color resistant fabric can be mainly sprayed inside or wrapping paper.

Mildew inhibitors, such as discolouration and flush, can be used to prevent mildew before spraying or after the treatment.

Nine, the inner box must be dry and its humidity should not exceed 10-12%. Before opening the shoes, it is recommended to open the shoe cover and dry it over the oven.

Spray or brush a small amount of mould inhibitor in the inner box; (for example, if the shoe box can not be processed with spray mould inhibitor, it can also be sprayed directly on the wrapping paper).

Ten. The humidity of the outer box should not exceed 10-12%. It is recommended to spray, brush and drip a little mildew inhibitor before sealing the container, then seal it around the joint and turn it into a special warehouse.

Eleven, if there is no special warehouse (wet room), the finished shoes should not be placed directly on the floor of the storehouse, should be separated by a pallet, keep the 50CM distance from the wall, check once a week, and provide the dynamic curve record of the warehouse temperature and humidity.

Twelve, before the use of the mold, do not disassemble the sealed package. If the Kaifeng is not used up, it should be sealed immediately to avoid damp and reduce the effectiveness. It is suggested that the drying bag should be put on the wrapping paper of the packaged shoes, which has better moisture absorption effect. If the hair boots suggest adding a bag to each boot,

Thirteen, the cationic mould proof paper is packed with moistureproof and waterproof vacuum isolation packaging. If it is not fully used, seal the seal well. It can be used continuously the next day. It is recommended that no more than one week after Kaifeng.

Fourteen. Skin materials warehouse, packing warehouse and finished goods warehouse should be regularly sprayed with mould inhibitor, sterilized or added with micro antibacterial agent to reduce the content of harmful microorganisms in the surrounding air and avoid contamination of materials or products.

Fifteen. It is suggested that the training professionals be responsible for the mould proof treatment so that the mould control measures can be implemented in a comprehensive and effective way.
