Problems solved by technology

The existing round-hole spinnerets have the same pore diameter of the spinneret micropores. In order to obtain fiber tows with different deniers and different thermal shrinkage rates, it is necessary to produce them through different multiples of traction devices according to their respective processes. Spinning The process is too complicated and the production cost is high

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] like figure 1 and figure 2 Shown, a kind of spinneret of the present invention, it comprises spinneret body 1, and described spinneret body 1 is circular, and the diameter of described spinneret body 1 is 180mm, and described spinneret One end surface of the body 1 is the feed surface 2, and the other end surface is the discharge surface 3, and the spinneret microhole 4 is provided on the spinneret body 1, and the spinneret microhole 4 is circular, and the spinneret microhole 4 is circular. The length-to-diameter ratio is 1.2-2.2. There are 60 spinneret microholes 4 on the spinneret body 1. They are divided into four groups of "V"-shaped structures, and each group of "V"-shaped structures is from the inner ring to the outer ring. The number of 4 spinneret microholes in the ring is 1, 2, 3, 4 and 5 respectively, and the diameters of the 4 spinn...

Abstract

The invention discloses a spinneret plate which comprises a spinneret plate body in a circular shape. The diameter of the spinneret plate body is 150-200 mm. One end face of the spinneret plate body is a feeding face, and the other end face of the spinneret plate body is a discharging face. The spinneret plate body is provided with round spinneret plate micropores. The diameter of each spinneret plate micropore is 0.35-0.65 mm, and the length-diameter ratio of each spinneret plate micropore is 1.2-2.2. The spinneret plate micropores are distributed in the spinneret plate body to form four sets of V-shaped structures. The pore diameters of the spinneret plate micropores in each group of V-shaped structure are gradually increased from the inner circle to the outer circle, and the pore diameters of the spinneret plate micropores in the same circle are the same. The spinneret plate micropores of the V-shaped structure are adopted, the pore diameters of the spinneret plate micropores are sequentially increased from the inner circle to the outer circle, distribution is reasonable, and the filament number is large; meanwhile, the spinneret plate has the good fiber cooling effect and has the huge market competitive power.

Description

technical field [0001] The invention relates to a spinneret, in particular to a round-hole spinneret for producing polyester filaments. Background technique [0002] High-strength coarse denier polyester filament generally adopts the production line of polyester industrial yarn. The melt extruded from the spinneret micro-holes is drawn and shaped in multiple stages, so that the product strength or dry heat shrinkage can meet the expected requirements. The existing round-hole spinnerets have the same pore diameter of the spinneret micropores. In order to obtain fiber tows with different deniers and different thermal shrinkage rates, it is necessary to produce them through different multiples of traction devices according to their respective processes. Spinning The process is too complicated and the production cost is high. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to overcome the deficiencies in the prior art and p...
