Who doesn’t like to have classic shoes, bags or clothes made of leather?
Bags, shoes and clothes made of leather are comfortable to use and add up our style quotient. Leather is used in bookbinding, leather wallpaper as a furniture covering. With such a wide application for leather, the leather industry is one of the most sort out and important industry since ages.

The leather manufacturing process is divided into three sub-processes: preparatory stages, tanning and crusting. All true leathers will undergo these sub-processes. “Leather tanning” is a general term for the numerous processing steps involved in converting animal hides or skins into finished leathers. Leather is produced from skins of four different types of wild and domestic animals: cattle, sheeps, goat and reptiles. Tanning is a process by which animal hides and skins are converted into leather. In the production and distribution of leather, two types of bio deterioration are encountered: bacterial (which generally applies to hides and skins in the early stages of the process) and fungal (which usually applies after tannage has taken place). Fungal bio deterioration can affect leather both in part-processed condition within the tannery and after it has been made into and distributed as a fully finished article. Fungal deterioration is apparent from the growth of moulds on leather. Moulds are infestation on various bio-substrates which tend to affect the physical structure and characteristics. We need to often review the nature of the infestation and protect it in time before it strikes the leather and leather goods. There are many strains of mould that are capable of growing on leather. Like all living organisms they need certain basics to grow and multiply: a source of moisture and a source of nutrient. In wet-blue leather the source of moisture is clear. In finished leather the moisture content is much lower and the growth of mould is less, but when transporting leather between different climatic zones, or if storing leather in an inappropriate manner, moisture build up in certain areas, such as just inside any packaging, can readily lead to the growth of mould.
Fungicides are an essential component for leather manufacture to prevent the occurrence of mould on part processed and finished leather. If used correctly and sourced from a reputable supplier, fungicides used within the leather making process present no risk to the consumer.

Kumar organics Kopthione Na (Sodium Pyrithione) is one of the most effective fungicide available in market. Kopthione Na is chemically called Sodium Pyrithione. It is an effective and high active broad-spectrum antimicrobial preservative that acts against moulds, yeasts, bacteria and algae. It is highly effective microbiocide even at very low usage levels. It is the stable water based dispersion which is dark yellow to amber colour liquid. Sodium Pyrithione is stable under normal environmental conditions if stored in closed, dark containers. At 100° C it is stable for 24 hours. In the light or in contact with weak oxidizing agents sodium pyrithione is converted to the disulfide, 2, 2-pyridyl-N-oxide disulfide. With stronger oxidizing agents or in alkaline solution (pH > 9.5) the substance is converted via a number of intermediates to the sulfonic acid. Kopthione Na interferes with the fungal germination and penetration process or inhibits fungal growth and reproduction within plant tissues. More specifically, they may interfere with cell division, may inhibit the activity of certain enzymes, or may alter the function of cell membranes. Kopthione Na is also compatible with leather and with process liquors, have stability on leather, non-discolouring, environmentally acceptable and most important is low toxic to humans

To conclude with, the increased usage of leather products, has made this industry a important industry. Since manufacturing leather is a highly sophisticated process, involves many stages where there are chances of contamination which will severely affect qualitative aspect of these products. Hence leather manufacturers should be very careful in selecting effective biocide (like Kopthione Na)
