TECHNICAL INFORMATION
+ Keep away from dusty, moist environments which are exposed to direct sunlight.
+ Do not place the product next to a heat source and keep the product at least 1m away from such source.
+ Do not place hot materials on the product. (Such as iron, teapot, etc.)
+ Under no circumstances use detergents and bleach.
+ Do not allow the product to get in touch with piercing and cutting materials.
+ Never apply chemicals such as solvents or alcohol on artificial leather.
+ Completely dry the liquid on the artificial leather with an absorbent piece of cloth.
+ Slightly moisture a soft piece of cloth with water and clean the stain softly.
+ Left the artificial leather to dry and wipe the remaining stain softly after it is dried.
+ Under no circumstances use cleaners containing detergents, alcohol and solvents.
Diesters made by phthalic acid with monohydric alcohols are called phthalates. They are mainly used to increase the elasticity of plastics. When added to plastics, they let long polyvinyl molecules to slide against one another. The phthalates show low water solubility, high oil solubility. They have carcinogenic features. Phthalates are used on vinyl and plastic containers, food packages, home appliances and in lots of body care products such as soaps and lotions.
As Besa Plastik Suni Deri Sanayi A.Ş., we use phthalate free products in our production since 2011. The advantages of using phthalate free products are given below:
+ They do not contain ortho phthalate esters, use of which is limited or banned mainly in European Countries.
+ They do not contain chemicals which are hazardous to health.
+ They yield much better results than equivalent products by means of technical values.
+ They do not cause any changes in the chemical structure of the polymer.
+ They provide the required changes in their physical and mechanical features.
+ They can generally turn all polymeric materials into gel easily and quickly.
+ They prevent cracking, increase the resistance and provide a smooth surface in lacquer applications.
+ They ensure having products with required elasticity.
+ They provide electricity resistance.
The most important point in shoemaking is controlling whether the artificial leather to be used on the model to be bonded to the sole or not. Some artificial leathers do not bond to the sole due to the chemicals on them and require wiping and sanding. Tests should be carried out with regard to such matter during R&D stage and a decision should be made on how the material will be used.
In manual assemblies, if solvents which are used in the activation of the heel counter and toe box are not dried well, cause the deformation of the artificial leather from both inside and outside. Enough time should be spent for the heel counter and toe box, which are wetted by solvents during shoemaking, to dry (solvents to volatilize) and shoemaking should be continued afterwards. The solvents which are not volatilized shall volatilize after the adhesion process and cause the lamination of the artificial leather to weaken, to remain on the skin and to cause the artificial leather to lose its elasticity and cause breakages during use for the end user.
Sampling:
A piece in the size of 150x30mm is cut from the artificial leather to be used.
Application:
Sole adhesive is applied on the sample we have taken. After being dried for 20 minutes, it is heated to a temperature between 65-75ºC and it is folded in two and the surfaces are bonded to one another. 25mm margin is left on both ends to carry out the opening process. The bonded artificial leather is pressed. After being cooled for 30 minutes, it is opened from the ends left open.
Result:
Application in accordance with the type of opening:
+ If the adhesive is being transferred from one end to the other, this artificial leather requires wiping. Wiping should be done with a cloth, not with a brush and usage of correct wiping water should be ensured.
+ If the artificial leather is torn during opening or separated from the cloth; no wiping is needed on the artificial leather.
