  • HDPE high density polyethylene
  • Tyvek* high density polyethylene
  • These materials are formed by the spinning of continuous filaments consisting of very fine fibres closely interconnected to one another and their subsequent bonding by heat and pressure. The result is a shiny white flashspun sheet that represents a printing surface with features of high opacity, resistance to chemical agents and strength. In virtue of these special features, these materials may be used to manufacture protective work clothing.
  • Tyvek ® which is distributed by DuPont provides some extremely general indications on how to laminate Tyvek ® .
  • it recommends the use of polyurethane or hot-melting adhesives and does not recommend the use of recycled cardboard because the latter can contain traces of solvents or binders which can cause the formation of bubbles.

  • the sheet of fabric comprising high density polyethylene (HDPE) has a grammage from 40 to 105 g/m 2 . If grammages higher than 105 g/m 2 are used, the fabric becomes excessively plasticated and is not sufficiently soft. If grammages lower than 40 g/m 2 are used, the fabric becomes excessively fragile for use in the production of articles and accessories such as shoes or bags.
  • the sheet of fabric comprising high density polyethylene (HDPE) preferably has a grammage from 70 g/m 2 to 80 g/m 2 , more preferably a grammage of 75 g/m 2 .

  • the method for manufacturing an article according to the present invention comprises the coupling method disclosed above and the steps of cutting at least one profile having an appropriate shape from the at least one sheet of fabric by die-cutting, and stitching the at least one profile having an appropriate shape to obtain the article.
  • one or more profiles will have to be cut and stitched together.
  • the article may be a shoe, a bag, a wallet, a keyholder, a belt, a hat etc.
  • the article is preferably a shoe.
  • the method for manufacturing an article also comprises a step of milling and/or dyeing the sheet of fabric, the step/s taking place before the coupling of the at least one reinforcing sheet to the sheet of fabric.
  • the appropriately-shaped profile is preferably stitched using a needle with a round point having a size of 65/9 and a distance between stitches from 2 to 3 stitches per centimetre with a low thread tension.
  • the size of sewing machine needles is expressed by a two-number metrical system, for example 60/8 for thin sewing needles and 120/16 for thicker needles. The higher number refers to the metric system and defines the diameter of the needle's shaft in hundreds of mm (Nm) . The smaller number refers to the system adopted in the United States and represents an arbitrary number from 8 to 19 also used to indicate the diameter of the needle's shaft.
  • the sewing machine needle system used is the 134 system.
  • a Groz-Beckert 134 DPx5 class R size 65 needle or a Schmetz 134 Serv 5 size 65 needle may be used.
  • the thread used for the stitching may be for example a polyester thread having titre 40 (where 40 is the size of the thread expressed in a unit known to the skilled in the art in the shoe sector; the size of the thread varies from 10, thicker size, to 80, thinner size) .
  • a white sheet of fabric was obtained as follows and a series of tests were performed thereon to verify the non- toxicity thereof.
  • the sheets were crumpled one by one and introduced into a milling drum (Gozzini, model 3.5 X 3.5 GIG 3500) together with 1 litre of a composition comprising 20% Urelux B129 (Keminter) and 80% water and 10 non-processed white skins weighing 1 kg each.
  • a milling drum Gozzini, model 3.5 X 3.5 GIG 3500
  • the milling drum was rotated at 6 rounds/minute for
  • the sheets were extracted from the milling drum and were left drying for one hour in open air.
  • the skins were extracted from the milling drum and kept for following milling cycles .
  • Table 1 shows the results of a series of toxicity tests .
  • the sheet of fabric obtained by the method according to the invention contains none of the tested toxic agents.
  • Example 2 the procedure was the same as in Example 1 with the difference that the sheets were laminated with a recycled and/or recyclable paper (grammage 26 g/m 2 ) soaked in vinyl adhesive (latex) and an additional reinforcing sheet of polyester was used.
  • the polyester reinforcing sheet had a grammage of 25 g/m 2 .
  • the reinforcing sheet, the vinyl adhesive, the recycled paper, the vinyl adhesive, and the Tyvek ® sheet were arranged in this order from top to bottom.
  • the recycled paper may be soaked in a vinyl adhesive and arranged between the reinforcing sheet and the Tyvek ® sheet (thereby the adhesive perfectly blends with the paper) .
  • the coupling is a cold coupling by means of a single-cylinder device for coupling leather (PCM Engineering) .
  • Example 2 The selection of the materials and of the adhesive used in Example 2 is the result of several tests which have led to unsatisfactory or in any case poor results.
  • Tests using paraffined paper having a grammage of 50 g/m 2 were performed by coupling the same with a thermoplastic adhesive. The result was unsatisfactory because the resulting sheet of fabric was very rigid and did not have the required resistance features to manufacture a shoe. The aesthetical appearance was also not very pleasant.
  • Example 2 A few sheets obtained in Example 2 were manually dyed with a fuchsia paint before milling.
  • each sheet of fabric was dipped for about 5 seconds in a fuchsia paint comprising 40% dimethyl ketone, aliphatic solvents, aniline dyes and fixing agents.
  • each sheet of fabric was laid on supports covered with an absorbing material for about 2 hours. This allows the complete evaporation of the solvents contained in the paint.
  • a dyed and milled sheet of fabric was cut by means of a dye-cutting process into several pieces having an appropriate shape for manufacturing a sneaker shoe. The pieces were then assembled and stitched with a needle having a round point (Goz Beckert needle, model 134 DPx5 class R size 65) using a stitching distance of 2 stitches per centimetre with a low thread tension.
  • the resulting shoe was subjected to a series of tests to verify thickness, resistance to stitching, tensile strength, elongation strength, resistance to bending, resistance to abrasion, maintenance of colour intensity upon light exposure, rubbing and aging.
  • the shoe obtained by the method according to the invention has an excellent stitching resistance, tensile and elongation strength, flexure strength and resistance to abrasion. Furthermore, the colour of the shoe does not vary after exposure to light, aging and rubbing.
  • Example 5 a neutral colour ballet flat was obtained.
  • a milled sheet of fabric was then cut by a dye-cutting process into several appropriately shaped pieces.
  • the pieces were then assembled and stitched with a needle with a round point (Goz Beckert needle, model 134 DPx5 class R size 65) by using a distance between stitches of 2 stitches per centimetre with a low thread tension.
  • the resulting ballet flat was not only soft, comfortable to wear, resistant and impermeable to rain, but also had a very fine aesthetical appearance.
  • Example 5 The shoe obtained in Example 5 was subjected to tests for measuring resistance to tearing, to stitching, to abrasion and to repeated bending to verify the quality thereof.
  • the tests are standard tests in the shoe manufacturer industry.
  • Table 3 summarises the results of the tests. Table 3
