ARRIGONI spa - SACHIM srl

This is how Paolo Arrigoni, a partner and director of Arrigoni Spa (Uggiate Trevano - CO) and of Sachim srl (Putignano - BA), as well as a partner of Artes srl (Schio - VI) and Arrigoni TEXAGRI (Tirgu - Romania) speaks of Mr. Giuseppe Starace, telling about his long professional relationship with him and his organization."
ARRIGONI Spa has been operating in the sector of technical textiles, particularly agrotextiles for many years (in this page the Company profile can be downloaded). In 2000 it took over the majority share of SACHIM, relaunching it with new and significant investments and creating a state-of-the-art facility for technology, quality and flexibility.

Success was mainly due to the team built up during time who trusted the global project and worked with enthusiasm and ability.

Among these, Mr. Giuseppe Starace has become a main actor in setting up and follow:

- the quality certifications ISO 14001 - ISO 9001 - EMAS
- training of young engineers working in SACHIM

- attention to energy saving and alternative energy adoption issues;
- the coordination of various research projects.

June Poster at Italian Congress: Si.Pro.Xy.Net - Sistemi di protezione dei vivai dagli insetti vettori di Xylella (Presentation of the results) in Xylella Fastidiosa: obiettivi, metodi e strategie - organized by the Apulian Regional Authority - June 13th, 2018 - University Campus Lecce (I) Authors: S. Castellano, A. Di Palma, G.S. Germinara, M. Lippolis, G. Scarascia Mugnozza, G. Starace A net protection system- specific for in field cultivations and for nurseries of olive trees and plant production- against the vectors of Xylella fastidiosa was studied. Mesh size, kind of fabric, threads typologies and radiometric properties were taken into account for the design optimization of the net. The mesh size of the net was settled on the geometric dimensions of the adult form of P. spumarius L.- one of three kinds of spittlebugs currently found in Apulia Region as vectors of to the bacterium. Experimental nets were performed in SACHIM factory in Putignano, Italy. Six nets with different kind of fabric and mesh size were tested. Preliminarily, nets were tested in laboratory; afterwards, an experimental apparatus (net-box) for in field test was built. Based on these first results, the net that better fulfilled the required performance was the mono-wire knitted one with the wider mesh tested. A further set of in field tests was performed in order to evaluate which height from the ground the vectors were able to reach on a net fence. At this aim, a wooden frame covered with nets was placed in an olive tree cultivation during the period July-October 2017; yellow adhesive traps were arranged on the vertical surfaces of the frame at different heights from the ground. The maximum value of captures was gathered during August with 14 specimens of both spittlebugs found in all the captures at different heights, and a maximum of 5 specimens of both spittlebugs found in the captures at 185cm from the ground.

In order to evaluate the influence of the texture
characteristics of agricultural nets on the air flow
passing through, a micro wind tunnel was built in the
“Testing and Engineering Laboratory” at the Sachim SRL, an Italian HDPE technical textiles manufacturer.
The wind tunnel allowed setting up the inclination of the net samples inside with respect to the air flow (90° perpendicular, 60°, 45°, 30°).
First results in terms of coefficient of discharge of 4 flat woven round monofilament HDPE nets are reported in this paper.
The net response to the air flow was based on the
discharge coefficient approach based on Bernoulli’s theory.
Results confirmed the parabolic dependence of the pressure drop on the square of the velocity and on the porosity by means of the parameter (1-ε2)/ε2. Concerning the influence of inclination of the net on loss coefficient, a correlation with sen2θ was found, described by an exponential regression curve depending on the porosity of the net.

A system made of technical textiles able to protect
cultivations from the damages of rain fall and to let
air to pass through, could increase the reliability of
predictions for the harvesting of many fruits such as cherries.
To this purpose a test device was designed and set up at Sachim srl to simulate and measure the rain permeability of agricultural nets at different inclinations, in terms of water
amount reduction passing through the net when exposed to rain.
The rain permeability index of the net was defined as the ratio between the water sprayed by the nozzles and the water gathered into the container under the net sample.
Nets with different geometrical characteristics such as
porosity, texture, kind of threads were tested; the effect of the net inclination was investigated, as well as the real contribution to the rain permeability decrease of a double layers textile scheme.
First results allowed to understand the influence of the main parameters to the rain permeability of the nets.
The porosity, defined as the ratio between the surface
of empties and the area of the net, seemed not to play a significant role as was observed when air permeability tests were performed.
The mesh size, the inclination of the net and the use of
the double layers scheme of the protection system were found to give the most significant change to the rain permeability behaviour of the nets.
Studies have also been carried out to overcome the present limits of single layer protection textiles in order to reach an advantageous as well as predictable low permeability to rain.

In order to evaluate the influence of the texture characteristics of agricultural nets on the air flow passing through them, a micro wind tunnel was designed and built in the testing and engineering laboratory of Sachim s.r.l., an Italian high-density polyethylene (HDPE) technical textiles manufacturer. The micro wind tunnel (0.1345 m diameter) allowed the simultaneous measurement of the air flowrate and the pressure drop through a net sample. The equipment was designed to set up the inclination of the net samples with respect of the airflow at fixed angles (90°, 60°, 45°, 30°). The variation of the pressure drop with the air velocity on four different flat woven round monofilament HDPE nets perpendicular to the air flow are here reported. In all cases the air velocity measured into the micro wind tunnel was above 4 m s–1 hence reported results do not consider low wind speed. Preliminarily, the loss coefficient was assumed as a function of porosity and Reynolds number, calculated with reference to the equivalent diameter of the pores, FS(Rel,ε) and showed percent deviations form experimental results in the range 14.6%÷25.3%. Hence a simplified expression of the loss coefficient, depending only on the porosity was proposed, FS(ε) which highlighted differences with experimental results in the range 3.5%÷20.3%. Finally, results were compared with those based on the Bernoulli’s principle found in the literature.

Fifteen HDPE agricultural nets were tested inside a micro wind tunnel (0.1345 m diameter) to establish their characteristic air flow rate vs pressure drop curves with velocities >4 m s−1. The air pressure drop through the net was accounted for, with reference to the Bernoulli scheme, by means of the loss coefficient. Experimental results confirmed those available in the literature, in terms of the dependence of the pressure drop on the velocity squared and the net porosity, ε, by means of the function . The influence of the orifice geometry was investigated and an effect equivalent to the increase in net porosity was identified in textile pores with elongated shapes. As with previous studies, the loss coefficient trend was found to fit the product of two functions, one depending on the porosity, and the other on the Reynolds number defined using the pore equivalent diameter. The calculated values of the loss coefficient show deviations from experimental results in the range of 19.9–41.1%. In addition, a new formulation for the loss coefficient, dependent only on the porosity and wet perimeter was proposed. Except for higher porosity nets the simplified formulation, showed the best match with the experimental data. The two formulations of the loss coefficient proposed here were compared with those found in the literature.
February Research paper on International Journal: Thermography-enhanced LCA (Life Cycle Assessment) for manufacturing sustainability assessment. The Case Study of an HDPE (High Density Polyethylene) Net Company in Italy.

LCA (Life Cycle Assessment) is nowadays a commonly implemented approach for evaluating resource consumptions and for benchmarking purposes. It suffers some limitations, mainly related to its assumptions on linear resource -consumption behaviour as well as on the non-context specific data. On the other hand, it is an extremely powerful tool for decision-making support in the sustainability assessment of manufacturing processes, providing its well-structured approach and widely accepted procedure. Deepening the assessment capabilities of such a tool is thus an important opportunity.
This paper is intended to build upon this concept by proposing an improved approach consisting in supplying in-process information concerning energy consumption and other process state conditions through thermography. The case of an Italian industrial company producing HDPE (High Density Polyethylene) nets for agriculture is taken as test bed case to show pros and cons of this idea. Actually, this approach resulted into a better assessment of the sustainability profile of the whole production process in terms of energy consumptions and environmental impacts. This in turn became an updated management tool for real-time decision making closer to the real conditions.

Development of Antibacterial Silver Treatments on HDPE Nets for Agriculture 
Journal of Applied Polymer Science  - Wiley

The defense mechanism of crops associated with the use of polymeric nets and fabrics is only physical and, hence, ineffective against the bacterial contaminations. The presence of an antibacterial agent associated with the use of conventional agro-textiles can represent a great advantage in the prevention of plant diseases and for food safety. The aim of this work was the development of antibacterial silver-coated HDPE nets for an innovative application such as agriculture. Antibacterial coatings on high-density polyethylene nets were obtained by a patented nanosilver deposition technique based on the in situ photo-reduction of a silver solution. The concentration of silver deposited was defined by testing different silver solutions from a biological point of view. Moreover, in order to improve the adhesion of the silver coating to the substrate, the nets underwent low-pressure plasma treatment before the silver deposition. The materials were characterized in terms of quality of the coating through scanning electron microscopy, and in terms of antibacterial capability on Gram positive and Gram negative bacteria through qualitative and quantitative microbiological tests. The most effective process parameters were defined and the importance of performing plasma pretreatment on this specific substrate was assessed.
