Image from the internet, must be deleted if infringed     The odour of newly purchased shoes/clothing is a not-so-pleasant experience for consumers, who are inevitably confused as to what causes the odour. Can it be toxic? Is it harmful to humans? Are these smelly products inferior? With these concerns, consumers may make backstage complaints or return the products directly, bringing a bad experience to customers while also causing some damage to their own brand impressions.   So how should footwear factories solve the odour problem to eliminate consumer concerns? Firstly, we need to be clear about where the odour is coming from and how it is assessed/detected before we can get a solution to the odour problem.     Images are from the internet, if infringed, they must be deleted       Where do footwear odours come from?     Image from the internet, if infringed, it must be deleted     Generally speaking, the main sources of odour are as follows:   (1) Mildew. As long as there is a suitable temperature and humidity environment, textile products may exist in the transportation, storage and use process of microbial metabolism.     Image from the network, such as invasion must be deleted       (2) High-boiling petroleum odour. High boiling range petroleum odour comes from some oil agents used in machines including garment production, or the use of additives containing petrol, paraffin etc. as lubricants in the textile production process.     Image from the network, if invaded must be deleted       (3) Fishy smell. The fishy smell is mainly caused by the smell of trimethylamine, a by-product of the baking process after the textiles have been finished with resin.      Image from the Internet, if invaded must be deleted   (4) Aromatic hydrocarbon odour. Aromatic hydrocarbon odour is caused by the use of auxiliaries containing aromatic hydrocarbon compounds during the production, printing and finishing of textiles.      Image from the Internet, if invaded must be deleted     Assessment and testing methods for odour in footwear and clothing   In fact, there are certain national standards and requirements for odour in textile products.   GB 18401-2010 "National Basic Safety Technical Code for Textile Products" requires textile products to be odourless. Odour is detected by the olfactory method, and the operator should be a trained and tested professional.   If the odour is detected as one or more of mould, high boiling range petroleum (e.g. petrol, paraffin), fishy or aromatic hydrocarbon odours, the sample is judged to be "odorous" and the odour category is recorded. Otherwise, the odour is judged to be "no odour".       Images are from the internet and must be deleted if infringed.     Testing method and precautions   (1) Immediately after opening the sample, carry out the test; (2) Test in a clean, odour-free environment; (3) The testers must wash their hands and wear gloves; (4) Two or three persons are required to carry out the test independently, with the final result of the sample being the result of the agreement between the two persons.       How can factories eliminate odours from footwear?   1. Maintain good ventilation in the workshop It is essential to keep the workshop well ventilated, as this will help to dissipate any odours that may be attached to the clothing. However, this practice requires a certain amount of space and time, so if the delivery time is short or there is not enough space to dry clothes, then this method is not available.     Picture from the network, such as invasion must be deleted     2. Use Topone CASANO active carbon treasure (coconut shell carbon deodoriser) Place Topone CASANO active carbon (deodorising and drying) in the bags of clothes, etc. to achieve the purpose of deodorisation.         Images from the internet, if invaded must be deleted     TOPONE Deodorising Carbon is made from coconut shell charcoal. After a series of treatments such as crushing and screening, the coconut shell activated carbon is bright in appearance and has good toughness, wear resistance, pressure resistance and superb adsorption characteristics. It is also oil resistant, non-clumping and not easily decayed.   Coconut shell activated carbon is generally in the form of crushed granules and flakes, while formed activated carbon, such as columnar and spherical activated carbon, is mostly coal-based. Coconut shell activated carbon has a small molecular pore structure. When activated carbon is placed in water, the air expelled when it adsorbs water molecules produces many very small blisters (visible to the naked eye) which float in dense densities on the water surface. Coal-based activated carbon, on the other hand, generally has a macromolecular pore structure and produces relatively large bubble phases.       Attached is the odour removal test of Topone's CASANO active carbon, you are welcome to contact us at any time for more details!
