    We offer a wide variety of short fiber cotton yarns in both raw and coloured and flame.

    Thanks to our experience in wool yarns, we manufacture high quality technical yarns for various sectors, as well as high value-added yarns.

    We manufacture from a metric 5 to a 30, to 1 and several strands.

    We offer yarns obtained from polypropylene fibers.

    The title of the polypropylene yarns as well as the number of strands will depend on the customer’s specifications.

    Polymer Overview

    It is a semi-crystalline nonpolar thermoplastic, of high hardness and rigidity, has excellent resistance to impact, and to corrosive chemicals.

    They are used in different industrial processes, due to their good electrical, chemical and mechanical properties. It chemically resists aqueous solutions of inorganic acids, weak organic acids, bleaches, alcohol and some oils.

    Chemical properties

    • Resistance to weak acids at room temperature: Very good
    • Resistance to weak alkalis at room temperature: Very good
    • Effects of sunlight: Regular
    • Combustion behaviour: Easily burns
    • Flame propagation: Keeps the flame
    • Burning behavior: Melts and drips

    We manufacture from metric 5 to 30, 1 and several strands.

    We manufacture from metric 5 to 50, with 1 and several strands. We offer yarns obtained from flame retardant polyester fibers.

    Polymer General: Polyester is a category of polymers containing the ester functional group in its main chain. The term polyester generally refers to synthetic polyesters (plastics), which include polycarbonate and especially polyethylene terephthalate. Polyester is formed synthetically from ethylene glycol plus terephthalic acid, producing the polymer or poltericolethane. As a result of the polymerization process, the fiber is obtained, which is the basis for the production of sewing threads and for the manufacture of fabrics.

    Chemical properties:

    • Strong Alkali: Lo
    • Weak Alkali: Low
    • Strong Acid: Good
    • Weak Acid: Excellent
    • Oxidizing agents: Excellent
    • Hydrolysis: Little

    We manufacture from metric 5 to 34, 1 and several strands.

    We manufacture from metric 5 to 30, 1 and multi-ply.

    We offer yarns obtained from Kanecaron® fibers and their blends.

    General information about the polymer:

    Kanecaron fibers, depending on their type, present differential characteristics in terms of oxygen limit (LOI. Percentage of oxygen necessary to achieve combustion), highlighting the fact that it is a fiber that does not melt but carbonizes, a factor that produces a rigid surface that, after combustion, continues to provide protection. The difficult flammability is permanent, without being deteriorated by the action of washing the garment. This characteristic is obtained directly by the modification of the polymer during the fiber extrusion process and cannot be altered during spinning, weaving or finishing, as well as by the care and maintenance operations to which the garments are subsequently subjected.

    With these fibers, physical performance is assured, i.e. high dimensional stability after a high number of washings, light fastness and alkali resistance.

    We manufacture from metric 5 to 30, 1 and several strands.

    We manufacture from metric 5 to 30, with 1 and several strands.

    We offer high performance yarns from different blends of synthetic fibers with Bekinox.

    Polymer Generalities:

    Bekinox is a metallic filament obtained from 100% stainless steel; depending on the percentage of steel fibers in the yarn composition, these will behave as: insulating, dissipative, conductive and antistatic.
