이와 같은 피브이시매트는 피브이시원료가 고가이고, 단위 체적당 중량이 무거워 상대적으로 원가가 저렴하고 탄력성이 우수한 폴리에틸렌발포시트 또는 EVA(Ethylene Vinyl Acetate)시트와 같은 경량발포시트를 접착제를 이용하여 복층으로 접착 제조하여 사용하였다.Such a fiberglass mat has a high cost and a heavy weight per unit volume, so it is relatively inexpensive, and a lightweight foam sheet such as a polyethylene foam sheet or EVA (Ethylene Vinyl Acetate) sheet with excellent elasticity is adhered in a double layer using an adhesive. It was prepared and used.

그러나, 상기한 바와 같은 종래의 피브이시매트는 그 제조과정에 접착제가 사용되어 그 사용과정에 환경오염물질이 유출되어 발암 또는 알레르기를 유발하는 문제점이 있었다.However, the conventional fibsi mat as described above has a problem in that an adhesive is used in the manufacturing process, and environmental pollutants are leaked during the use process, causing carcinogenesis or allergies.

한편, 대한민국 특허공개 제10-2017-0121009호에 소개된 바와 같이 서로 다른 재질로 이루어진 표면층과 이면층을 접착제를 사용하지 않고 접착대상물의 접착면을 열풍에 의하여 직접가열하여 접합한 피브이시매트제조방법이 공개되어 있으나, 서로 다른 재질로 이루어져 그 접합이 견고하게 이루어지지 않은 문제점이 있었다.Meanwhile, as introduced in Korean Patent Laid-Open No. 10-2017-0121009, a method for manufacturing a fibrous mat in which the surface layer and the back layer made of different materials are directly heated by hot air without using an adhesive and the adhesive surface of the object to be bonded is bonded. Although this has been disclosed, there is a problem that the bonding is not made firmly made of different materials.
