摘要： Crystalline polymers are drawn using pressurized saturated steam having an absolute pressure of at least 2.0 kg/cm2 as a drawing medium. The steam is charged into an airtight container having a drawable material inlet for feeding a drawable material and a drawn product outlet for withdrawing a drawn product. Pressurized water is utilized to prevent leakage of the pressurized saturated steam through the inlet and outlet and to cool the drawn product, so that the product formed of a crystalline polymer has improved physical properties.

摘要： A drawing device for handling a wide range of drawable thermoplastic resin materials including a first pressurizing tank and first buffer tank on an upstream side, and a second pressurizing tank and second buffer tank on a downstream side are disposed along a drawing tank having pressurized steam and a discharge unit connected to it. A medium supply and discharge may be connected to each of the first and second pressurizing tanks, and the first and second buffer tanks. Opening members may be disposed on respective upstream and downstream ports along the drawing tank. Small amounts of pressurizing medium may then be allowed to flow into the drawing tank through upstream and downstream ports. Next, material may be supplied from the upstream port into the drawing tank where pressurized steam may be introduced in airtight conditions, and then drawn to the downstream port, thereby producing a drawable thermoplastic resin material.

摘要： When a drawable material is forcibly drawn for obtaining a drawn product formed of a crystalline polymer, there is caused a failure such as draw breaking, and the drawn product formed of a crystalline polymer that can be industrially produced by a conventional drawing method has upper limits of physical property values depending upon the material of said drawn product formed of a crystalline polymer. In the present invention, pressurized saturated steam having an absolute pressure of at least 2.0 kg/cm2 as a drawing medium is charged into an airtight container having a drawable material inlet for feeding a drawable material thereinto and a drawn product outlet for withdrawing a drawn product formed by drawing the drawable material, to provide a drawing chamber; pressurized water is utilized to prevent the leakage of the pressurized saturated steam through said drawable material inlet and said drawn product outlet, respectively; a drawable material is introduced into the pressurized water which is preventing the leakage of the pressurized saturated steam from said drawable material inlet; said drawable material is introduced through said drawable material inlet to the drawing chamber to draw the drawable material after water adheres to the drawable material surface; and then, a drawn product withdrawn through said drawn product outlet is introduced into the pressurized water which is preventing the leakage of the pressurized saturated steam through said drawn product outlet, to cool the drawn product, so that there can be obtained a drawn product formed of a crystalline polymer having more desirable physical properties.
