Народ, пожалуйста, помогите перевести фразу coated core-filled yarns. Что это? нити с заполненным сердечником и нанесенным покрытием? или можно короче?

Контекст:

Outer exposed layer of coated core-filled yarns flooring and wall fabric
The invention is a performance fabric having an outer exposed layer of coated core-filled yarns, such as those having a polyvinylchloride coating surrounding a polyester core, or even non-core filled yarn such as polyvinylchloride yarns woven to form an upper layer which is connected to a polyester or other core layer, preferably with an adhesive such as a weatherproof adhesive, and a preferred urethane backing coating applied to a lower surface of the core layer
