Embodiment 1

[0031]Component A adopts linear PPS slices with an MFR of 210g / 10min. In order to avoid the blockage of polyphenylene sulfide slices during the screw melt extrusion process, causing pressure fluctuations, oxidative degradation and crosslinking, etc., before melt spinning, Dry in known vacuum drum or pre-crystallization drying equipment, moisture content is 23PPM. When melting, the screw temperature is 280-325°C; for component B, PET chips with an intrinsic viscosity of 0.67 are used. After drying, the moisture content is 21PPM, and the screw temperature is 278-295°C when melting. The temperature of the composite box is controlled at 300°C, the spinneret hole diameter is 0.3mm, the length-to-diameter ratio (L / D) is 6, the number of spinneret holes is 60, the slow cooling zone is 10cm below the spinneret, and the slow cooling zone The temperature is 240°C; the wind temperature in the cooling zone is 25°C; the oiling rate is 1.5%; three draftings are used for drafting, the total ...

Embodiment 2

[0032] The spinning conditions of Example 2 are the same as in Example 1, except that four drafting processes are adopted during drafting, and the drafting conditions and physical property indexes are shown in Table 1.

Embodiment 3

[0033] Component A of Example 3 is the same as that of Example 1. Component B is PEN with a water content of 26PPM, and the screw temperature is 275-290°C during melting. The spinning and drawing winding conditions are the same as in Example 1.

Abstract

The invention relates to one-step complete sets of equipment and a production method of polyphenylene sulfide composite filament. Linear polyphenylene sulfide (PPS) is taken as cortex and polyester ethylene terephthalate (PET) or polyester ethylene-acid naphthalene (PEN) or polycaprolactum (PA6) or polyhexamethylene adipamide (PA66) is taken as a skin-core structure of a core layer in the polyphenylene sulfide composite filament. The composite filament one-step complete sets of equipment and the production method are adopted to produce polyphenylene sulfide composite filament. The complete sets of equipment and the production method include a spinning draft winding combination machine and a polyphenylene sulfide composite spinning preparation method. The polyphenylene sulfide composite filament is cheap with high quality. Compared with single component polyphenylene sulfide filament, the raw material cost can be reduced by more than 30-40 percent. The fiber which is used as filtering material can be widely applied to environmental protection industry.

Description

technical field [0001] The invention belongs to the technical field of special chemical fibers, and in particular relates to a one-step complete set of equipment and a production method for polyphenylene sulfide composite filaments. Background technique [0002] Polyphenylene sulfide (English name Polyphenylene Sulfide, abbreviated as PPS) fiber was first successfully developed by Philips Petroleum Company of the United States. The company started industrial production of PPS resin in 1973, developed fiber-grade PPS resin in 1979, and industrialized PPS short fiber in 1983. Due to the excellent performance of polyphenylene sulfide fiber, Japan's Toyobo, Toray, Teijin and German Bayer have also developed and produced polyphenylene sulfide fiber. [0003] Polyphenylene sulfide can be made into filaments and short fibers. Due to its good textile processing performance and excellent chemical resistance, thermal stability, high temperature resistance and flame retardancy, it is ...
