Ydinkehrätty lanka tai ydinkehrätty lanka on ainutlaatuinen tekstiilitekniikka, jossa eri kuidut yhdistetään tiiviisti kehruun avulla.ydinkehrätty  lankaTämän tekniikan takana on käyttää "ydintä", joka voi olla mikä tahansa kuitu, jolla on lujuutta, kun taas muut kuidut on kääritty sen ympärille. Tämä mahdollistaa yhden langan, jolla on sekä sitkeys että pehmeys, mikä ei ole mahdollista useimmilla perinteisillä langoilla.

Vahvuus ja pehmeys yhdistelmä
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.

Ydinkehrätyn langan sovellukset
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.

Lopuksi
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
