Calloni produces synthetic raffia-type yarns in HDPE and PP, in various widths and thicknesses, in counts from 400 denier up to 6000 denier. These yarns can undergo various treatments such as fibrillation (which serves to soften the tape and make it more workable, with a more textile feel), colouring, lubrication, UV treatment, flame retardant treatment and twisting, which rounds yarns that start out flat. We can investigate other treatments or particular processes on request. Our product range also includes short staple polyester yarn, single strand or twisted, dyed and lubricated. Its main use is as a sewing thread. The yarn is wound onto cylindrical or conical bobbins of various sizes, as per specifications in the various sections or at the customer's request.
