FAQ

Tutte le informazioni della nostra Azienda Pranem

  • Who is PRANEM?
    Pranem, a company active in the sector of technical textile materials, was founded in 2011 by the will of Gabriele Diddi, taking up the legacy of the family company, Diddi & Gori. ​ Based in Prato, famous throughout the world for its ability to give new life to used clothes. Technological capital of the recovery of every type of textile, which, suitably worked, gives rise to new fibers and new fabrics. Pranem declines this historical technological heritage in the technical components of the shoe and in particular in the sector of work/safety footwear in compliance with < strong>international standards that regulate it. Tall this with extreme attention to e< /strong>co-sustainability, using water-based and solvent-free chemicals. Innovation, Technology, Competence and Experience, are nothing more than an added value to the quality of Made in Italy.
  • What type of product does Pranem offer?
    Pranem offers a wide range of products for the world of footwear, in all its variants: classic, sports, mountain, sneakers, work and safety.< /p> NONWOVENS - JERSEY - FOAMS - FILMS - TAPES are the technical textile articles that we make for our customers.
  • How can I become a Pranem customer?

  • What is the difference between antistatic and conductive?
    A material is defined as antistatic or conductive based on its ability to "transport", or rather dissipate, static electricity. This property is verified through the measurement of the resistance to the passage of electrons opposed by the material, when it is subjected to an electric potential difference. It is antistatic for values between 10⁵ and 10⁹ Ohm and it is conductive between 10² and 10⁵ Ohm
  • How are antistatic/or conductive materials made?
    In general, there are two methods. Through chemical treatments or through raw materials with conductive characteristics. Chemical Treatments: these are additives that have the property of absorbing humidity from the air. The latter is the "vehicle" that dissipates static electricity. Simple and cheap to use, they allow antistatic but not conductivity. Furthermore, very often they are not stable over time. If not used correctly, they tend to migrate with the result that the shoe risks becoming insulating. Conductive raw materials: it concerns steel, silver, carbon fibers, (...) or additives such as carbon black (...). Permanent conductivity is obtained. More expensive but they guarantee performance for the entire life of the shoe.
  • What is the difference between recycled and recyclable?
    Recycled indicates a product obtained from raw materials from waste products of other processes (pre-consumer) or which have finished their cycle of use (post-consumer) e.g. clothes. Recyclable indicates a finished product which at the end of its use, can be reintroduced into a production chain. Often the chemical nature of the different components used makes it very complex and expensive , when real recyclability is impossible.
  • What is the difference between pre-consumer and post-consumer recycled?
    Pre-consumption: identifies scrap or defective products that cannot be placed on the market. e.g. textile fibers and chemicals. These, properly processed, represent the raw material for many applications, for example almost all of our non-woven fabrics used for midsoles and linings. Post-consumer: identifies the recovery of materials that have completed their life cycle and which would be destined for disposal. Typically the clothes and textile furnishings. In this case, through a working process, new fiber is obtained which gives rise to our multicolor Recy and Safety line.
  • How is the thermal insulation of a material measured?
    By insulation from external cold (thermal), we mean the ability of a material to maintain the internal temperature unchanged for as long as possible. The specific test is called RCT, an acronym for resistance to heat transfer. The higher the value, the better the degree of insulation. perspiration is also fundamental, which prevents evaporation from the skin from condensing, generating a cold sensation. ElaTherm combines perspiration with insulation.
  • What is meant by viscoelastic memory foam?
    Viscoelastic is a foam that deforms when subjected to pressure, recovering its original shape when it is at rest. The peculiarity that differentiates it from other types of elastic foams is the ability to oppose the compression, the same push (force) in every point even in the presence of non-homogeneous deformations. In other words, in the case of a shoe, the pressure exerted by the heel, arch and forefoot are different. This generates a different fatigue with possible manifestation of pain in specific areas of the limb. A viscoelastic foam, in addition to adapting to the shape of the foot, distributes forces evenly over the entire surface, reducing fatigue with a more comfortable walk.
  • What is the difference between Latex foam and Polyurethane foam?
    Both have an open cell structure, i.e. they form a "spongy" lattice that allows perspiration. The latter will be more or less high depending on the density of the foam. Those in Latex are produced with water-based raw materials, the foam is created mechanically by introducing air into the liquid compound. They are used for flat insoles and can be spread on many types of fabrics. Those in Polyurethane expanded are based solvents, the foam is obtained by chemical reaction of two components basis. Coupled with fabrics, they are used for thermoformed insoles.
  • What is the difference between non-woven and cellulosic midsole?
    Non-woven fabrics for midsoles are generally composed of a weave of fibers subsequently bonded with water-based resins. They have high resistance to bending, can be sewn to the upper, are breathable, do not delaminate, the surface is "hairy", they absorb a greater amount of glue when assembling the upper. p> Cellulosic for midsoles are made with cellulose compressed and bonded with water-based resins. They have a smooth surface, they do not absorb glue during assembly to the upper, they deform in the presence of high humidity and cannot be sewn, usually cheaper.
