REACH CERTIFICATION
The acronym REACH originates from English and stands for “Registration, Evaluation, Authorization, and Restriction of Chemicals.” REACH is a regulation of the European Union, adopted to improve the protection of human health and the environment from risks associated with chemicals, while simultaneously increasing the competitiveness of the EU chemicals industry. It also promotes alternative methods for assessing hazards that may arise from substances, with the aim of reducing the number of experiments conducted on animals. In principle, REACH applies to all chemical substances: not only those used in industrial processes, but also those used in everyday life, such as cleaning products or paints, as well as those present in articles like clothing, furniture, and electrical appliances. For this reason, this regulation has an impact on the majority of companies within the EU. The REACH regulation places the burden of proof on companies. Therefore, companies, in accordance with the regulation, must identify and manage the risks associated with the substances they produce and market within the European Union. They must demonstrate to the European Chemicals Agency (ECHA) how to use these substances without incurring risks and communicate risk management measures to users. Thanks to its sustainable, natural, and innovative production process, the company Duedilatte srl has obtained the REACH certification for milk fibre.
STANDARD 100 BY OEKO-TEX® CERTIFICATION
This is a system of independent and internationally standardised controls and certification for raw materials, semi-finished products, and finished products in the textile sector at every stage of processing, as well as for the associated materials used. Examples of certifiable items include: raw, dyed, and finished yarns, fabrics and knits, accessories like buttons, zippers, sewing threads, or labels, various types of packaged items (clothing of all kinds, home textiles and furnishings, bed linens, towels, etc.). Thanks to its decades of experience, the STANDARD 100 by OEKO-TEX® contributes to ensuring a high and effective product safety from the consumer’s perspective. The verification criteria and limit values are far more demanding than the parameters valid at the national and international levels. The thorough product inspections and periodic company audits also help raise awareness within the industry about the responsible use of chemicals, in the long term and on a global scale. This concept has attributed a dominant role to STANDARD 100 by OEKO-TEX® for many years. The Duedilatte fabric produced at the facilities of our certified industrial partners has obtained STANDARD 100 by OEKO-TEX® certification.
CERTIFICATION OF TOTAL AMINO ACID DETERMINATION
Proteins are built on a variety of different building blocks, and essential amino acids are one of these. Amino acids are the bricks of proteins and are vital for the proper functioning of the body. The body requires 22 amino acids for proper functioning; eight out of these 22 are essential amino acids,
Leucine*
Isoleucine*
Valine*
Phenylalanine*
Threonine*
Lysine*
Tryptophan
Methionine
Duedilatte milk fibre contains as many as 18 significant total amino acids present in the fibre (i.e. after acid hydrolysis to break down proteins), including 6 out of the eight amino acids essential for the body.
*Present in Duedilatte fibre.
ANTIBACTERIAL CERTIFICATION – ASTM E2149-13A
It is a test method for determining the antimicrobial efficacy of antimicrobial agents under conditions of dynamic contact. This is a recommended test for testing materials such as fabric, paper, etc. The number of viable organisms present is determined and the percent reduction is calculated by comparing the recovery from appropriate control samples, which have not been treated with antimicrobial additives. The tests conducted on raw Duedilatte fabric (not subjected to any specific antibacterial chemical treatment) certify that the fabric is NATURALLY ANTIBACTERIAL at the level of 83%.
COMFORT TEST ISO 11092:2014: PHYSIOLOGICAL PROPERTIES OF MILK FABRIC
Comfort represents the degree of well-being offered by a product, determined by the sensation perceived when it is worn. Thermophysiological comfort represents the indicator par excellence that allows us to move from the concept of sensation to that of objective evaluation. ISO 11092 standard test uses the sweat-protected hotplate method, also known as the “skin model” method, to simulate the process of heat and moisture transfer near the human skin, and to test the thermal resistance and water vapour resistance of fabrics under steady-state conditions to evaluate tissue comfort. The comfort of textile materials mainly includes the complex combination of heat and water vapour transmission, each process can occur individually or simultaneously, this test provides a test method for the thermal resistance and water vapour resistance of fabrics under stationary conditions, better simulating the actual wear of clothing. Tests are performed by placing the fabric with the side usually facing towards the human body placed in direct contact with the porous hotplate.
Test conditions:
◉ T°= 35 °C +/- 0.1 (tested temperature)
◉ RH% = 40% +/- 3 (humidity factor)
◉ Air speed = 1 m/s +/- 0.05
WATER VAPOR RESISTANCE (RET)
MEASUREMENT RESULT OBTAINED: 4.188 m2Pa/W (pascal square metres per watt)
Water Vapour Resistance RET is the difference in water vapour pressure between the two faces of the material, divided by the evaporative heat flux per unit area in the direction of the gradient. The heat flux of evaporation can consist of both diffusive and convective components. Water vapour resistance is a specific quantity of textile and composite materials that determines the latent heat flux of evaporation across a given surface when a time-stable water vapour pressure gradient is applied. The value that emerged from the comfort tests shows how the milk fabric is particularly breathable and therefore comfortable.
THERMAL RESISTANCE MEASUREMENT (RCT)
RESULT OBTAINED: 0.0373 m2K/W (square metres kelvin per watt)
The thermal resistance of clothing represents the resistance to the flow of heat opposed by the clothing and the layer of air between the clothing and the skin. In the international system, thermal resistance is expressed in m2 °C/W, even if, in general, an inconsistent unit of measurement is used, the “clo”, 1 clo = 0.155 m2 °C/W. The Duedilatte fabric has a Clo index of 0.24 which defines the comfort of the fabric as extremely comfortable.
UPF – ULTRAVIOLET PROTECTION FACTOR, UV PROTECTION SUN FACTOR
RESULT OBTAINED 25.3007% in natural milky white color
Instrument: UV-VIS-NIR spectrophotometer lambda 950 interfaced with integrating sphere 150 (Labsphere)
Ultraviolet rays are divided into UVA, UVB and UVC. The latter are blocked by the ozone layer, UVB is partially filtered by the atmosphere and clouds, while UVA can also pass through glass. UVAs are present all year round and unfortunately they can also act in the event of a cloudy sky because they reach our skin even through glass. As they can also reach the dermis, they are one of the main causes of the production of free radicals, responsible for premature photo-ageing, skin reactivity phenomena and pigmentation disorders. UVB rays are much stronger and can cause sunburn, but both a cloudy day and glass can reduce their intensity. They are the ones that determine the appearance of a tan based on the reaction with our skin, but are also responsible for redness and allergic reactions. The UPS factor is an estimate of the shade capacity of the fabric, so the higher the number indicated by the test result, the higher the degree of sun protection of the fabric. The UPF factor is influenced by numerous factors: density of the weave, colour of the fabric, nature of the material, etc. The Duedilatte fabric in its 145 g/m2 jersey structure and in its natural milk white colour, although remaining a very light and almost transparent fabric, it shows a very important protection factor of 25.3%. It can be deduced that a higher density of fabric combined with a coloured pigmentation could lead the Duedilatte fabric to be defined as natural anti-UV fabric.
