Coffee harvesting in Colombia is carried out naturally by detaching mature fruits by hand, in more than 10 collection times a year. During the harvesting season, fruits accidentally fall on the ground leading the growers to economic losses and favoring coffee borer (hypothenemus hampei) infestation. In order to facilitate the coffee pickers work and to reduce losses, a device to aid manual coffee harvesting was developed at Cenicafe. The textile pack of the device can be carried in the picker’s back or waist and, although seams and fibers are resistant under work conditions, they have shown quick wearing. This work pursued the search of new fabrics to reduce the manufacturing cost and to increase the endurance of the materials used to make new devices. A backpack was designed with simple patterns, cuts and seams. Tensile tests as well as friction tests were conducted with three different fabrics. The tensile tests were run in a universal testing machine and the friction tests were run in an experimental setup specially designed to exert friction to the fabrics with actual coffee branches. According to a 5% Duncan test, the fabric Milenio showed the best tensile resistance, surpassing 5.43 times the Rafia-PP fabric and 1.28 times the Reebag fabric. With regard to friction resistance, the Milenio and Reebag fabrics showed durability greater than 2.5 years, while the Rafia-PP fabric showed a friction durability of one year (160 field workdays).
