BLC leather consulting services can help your business overcome leather production and manufacturing problems, such as:

Problems with Spue on Leather Products

Spue exhibits itself as a white powdery substance on the surface of leather products and can sometimes resemble mould. Most spues seen on leather products are caused by fats or oils which have migrated to the leather surface and crystallised giving a white appearance. Spue can also be caused by excess inorganic salts in the leather. Spue can sometimes be cleaned from the leather but it is often prone to return. Knowing the cause of the spue allows for changes to be made to prevent re-occurrence of the problem. BLC leather consulting can help with identifying spue and provide solutions on how to eliminate future re-occurrences on leather and leather goods.

Foil and Finish Failure on Leather

Metallic foiled leathers are a specialist finish type and manufacturers oftem experience problems in this area. In extreme cases, there can be a complete loss of the metallic layer from the leather. Damage during one part of product manufacture can also make the foil finish become more susceptible to further damage during subsequent operations. BLC leather consulting can analyse foiled leathers to identify the cause of foil or finish failure and will advise you on how to avoid problems in the future.

Colour Transfer / Migration / Bleed from Leather

Colour transfer (also known as colour migration or bleed) is typically caused by excess or unfixed dyes in the leather or dyes used in the finishing process. Incompatibility of materials such as adhesives or lining materials can also cause colour transfer problems. BLC leather consulting and testing services can be used to identify problematic materials and offer practical solutions to the problem. 

Corrosion & Tarnishing of Metal Components used in Leather Products

Metallic components are often used in conjunction with leather. Wrong choice of materials or poor plating of metals can lead to potential issues of tarnishing from use. Some leathers also can contain substances which can be aggressive towards metallic components causing unwanted corrosion and tranishing. BLC leather consulting services can help identify potential hardware issues and offer assistance with material compatibility.

Colour Fading / Fastness / Lightfastness of Leather

Poor lightfastness can be a serious issue with leather goods and is often not highlighted until after the product has been made. The problem tends to be related to choice of dye but tanning and process materials can also impact on the lightfastness of the leather. Certain dye colours and pale shades can be particularly problematic. BLC leather consulting can offer practical advice and support on how to select the right materials to achieve good lightfastness properties.
