적층폴리에스테르필름의 제조방법Manufacturing method of laminated polyester film

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

Claims (1)

입자크기가 다른 불활성화합물을 혼합시켜 2종의 폴리에스테르를 제조하고 이들을 공압출하여 적층 폴리에스테르필름을 제조함에 있어서, 자성체를 도포하지 않을 폴리에스테르필름 I은 그 정마찰계수가 0.6이하가 되도록 입자크기가 0.1-12μ 범위의 것을 혼합시키고, 자성체를 도포할 폴리에스테르필름 Ⅱ는 그 정마찰계수가 폴리에스테르필름 Ⅰ보다 적어도 0.05이상이 크도록 입자크기가 0.1mμ-0.09μ범위의것을 혼합시킴을 특징으로 하는 이를 이축연신하여 제막시키는 적층폴리에스테르필름의 제조방법.In preparing two kinds of polyesters by mixing inert compounds having different particle sizes and coextrusion them to produce a laminated polyester film, the polyester film I which is not coated with a magnetic body has particles having a static friction coefficient of 0.6 or less. The polyester film II to be mixed in the range of 0.1-12μ in size, and the magnetic film is to be mixed in the particle size of 0.1mμ-0.09μ so that the static friction coefficient is at least 0.05 or more than the polyester film I. A method for producing a laminated polyester film, which is biaxially stretched to form a film. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
