sheath-core的音标

The paper adopt the hot-melt fibers ( ES fibers) which is sheath-core structure, at a certain pressure and temperature, the sheath of the fiber was melted and the fibers fused together, so that, the tensile strength of the paper is advanced.

采用皮芯结构的低熔点纤维，在一定的热压条件下，皮层纤维熔化，纤维间相互粘结，提高纸页的强度。

Finally, we got the reasonable parameters by the simulation and designed a set of large-capacity sheath-core spinning component with the basic parameters of the company. This provided theoretical guidance for the company in production technology of low-melting point polyester.

最后，通过模拟所得参数和某公司的设计基础参数设计出一套大容量皮芯型复合纺丝组件，并结合该公司实际生产情况对低熔点棉生产工艺进行研究，取得了良好的效果。

PA/ PET sheath-core composite filaments for tyre cords are produced on the self-made 920 mm twin screw composite spinning machine from chips of high viscosity polyester and high molecular weight polyamide.
