What are the main types of thread?

Different types of hilum are used in the fabrication of fabrics of varied design, texture, purpose, etc. Depending on its characteristics and technique of elaboration, the hilo can be simple, twisted, composed, wired, textured, doubled or continuous.


First of all, the simple structured loop is easily recognizable because it has a single twist, while the twisted loop is formed with two or more simple loops of similar length, twisted one on top of the other. With that, if an additional resistance is obtained, which helps to understand why there is a high demand from the twisted thread manufacturer.


On the other hand, the wired loop is composed of multiple loops twisted by means of several twists. This structure should not be confused with the folded hilo, the result of the combination of a set of simple wires, wired or twisted.


The creation of a continuous hilum starts from one or multiple filaments with a wavy effect. More sophisticated is the textured loop, formed by several loops of continuous filament with wavy effect. This treatment (textured) is carried out to give the hair a rified appearance, being very common in synthetic fibers such as PA, PV, PAN, acetate and triacetate, for example.


With respect to the hilo cubierto, this one is manufactured as a result of the coiling of conventional or metallic threads around the other forming a suerte of soul. On the other hand, the elastic structure loops can be presented individually or in combination with natural or synthetic filaments. Due to its elastic conditions, it is a type of hilum ideal for the confection of bikinis, bathers, chandales and other sportswear.


Finally, the so-called ‘fantasy’ strands are designed with a mix of filaments and fibers of different classes, with the aim of achieving a novel and original appearance. Used in avant-garde garments and fabrics.
