O fio fiado com núcleo ou fio fiado com núcleo é uma tecnologia têxtil única em que diferentes fibras são combinadas estreitamente por meio da fiação.fio fiado núcleo Por trás dessa tecnologia está o uso de um "núcleo" que pode ser qualquer fibra que tenha resistência enquanto outras fibras são enroladas em torno dela. Isso nos permite ter um fio com tenacidade e maciez, o que não é possível com a maioria dos fios tradicionais.

Combinação de Força e Suavidade
What makes Core Spun Yarn so good is its ability to combine strength and softness in the perfect way. For instance, polyester fiber has high tensile strength as well as resistance against wear but feels rough therefore making it unsuitable for creating delicate garments like underwear. On the other hand, cotton fiber may be very smooth but lacks enough durability hence not being appropriate for items subjected to gravity or friction forces. Nevertheless, if we employ Core Spun Yarn technology then we will use polyester fiber as the “core” while cotton fiber forms the “sheath” resulting in tough yet soft yarns.

Aplicações do fio fiado com núcleo
Core-spun yarn finds wide applications across many sectors. Within the clothing industry, it is used in making denim jeans, work wear, and sportswear among others whereas at home sheets can be made from it together with curtains, sofa covers or even carpets where need be. Car seats , seat belts filters are also industrial products that can be produced using core spun yarns.

Em conclusão
Basically what I mean is that the advent of this technique has revolutionized textile industry since now there’s no more trade-off between robustness and comfort brought about by core spun yarns
