Embodiment 1

[0014] A method for preparing a matte fiber with wool-like effect, using polyester chips with an intrinsic viscosity of 0.680 and a titanium dioxide content of 2.5% as a raw material, and spinning with a hot-roller high-speed drafting spinning machine. Drying, drafting, setting temperature and drafting ratio, in order to achieve normal spinning to obtain a matt fiber product with a wool-like effect, the monofilament fineness of the matt fiber product with a wool-like effect is 1dpf~20dpf , the total fineness is 30dtex~150dtex, and the f number is 12~108. Wherein the spinning winding speed is 3800 m / min, and the shape of the spinneret hole of the spinneret produced by it is as follows: figure 1 As shown, it includes a horizontally arranged slotted hole 1 and six vertically arranged vertical holes 2 arranged horizontally along the slotted hole 1 and connected with the slotted hole 1. The two ends of the vertical hole 2 are respectively A round hole 3 is provided, and the diamet...

Embodiment 2

[0016] A method for preparing a matte fiber with wool-like effect, using polyester chips with an intrinsic viscosity of 0.680 and a titanium dioxide content of 3% as a raw material, and spinning with a hot roller high-speed draft spinning machine, and selecting appropriate Drying, drafting, setting temperature and drafting ratio, in order to achieve normal spinning to obtain a matt fiber product with a wool-like effect, the monofilament fineness of the matt fiber product with a wool-like effect is 1dpf~20dpf , the total fineness is 30dtex~150dtex, and the f number is 12~108. Wherein the spinning winding speed is 5200 m / min, and the shape of the spinneret hole of the spinneret produced by it is as follows: figure 1 As shown, it includes a horizontally arranged slotted hole 1 and six vertically arranged vertical holes 2 arranged horizontally along the slotted hole 1 and connected with the slotted hole 1. The two ends of the vertical hole 2 are respectively A round hole 3 is pro...

Embodiment 3

[0018] A method for preparing a matte fiber with wool-like effect, using polyester chips with an intrinsic viscosity of 0.680 and a titanium dioxide content of 2.8% as a raw material, and spinning with a hot roller high-speed drafting spinning machine, and selecting appropriate Drying, drafting, setting temperature and drafting ratio, in order to achieve normal spinning to obtain a matt fiber product with a wool-like effect, the monofilament fineness of the matt fiber product with a wool-like effect is 1dpf~20dpf , the total fineness is 30dtex~150dtex, and the f number is 12~108. Wherein the spinning winding speed is 4500 m / min, and the shape of the spinneret hole of the spinneret produced by it is as follows: figure 1 As shown, it includes a horizontally arranged slotted hole 1 and six vertically arranged vertical holes 2 arranged horizontally along the slotted hole 1 and connected with the slotted hole 1. The two ends of the vertical hole 2 are respectively A circular hole ...

Abstract

The invention relates to a method for preparing dull fiber with a wool-like effect. The method comprises the following steps of: spinning polyester chips which contain 2.5 to 3 percent of titanium dioxide and serve as a raw material by utilizing a heat roller type high-speed drafting spinning machine; and selecting an appropriate drying temperature, an appropriate drafting temperature, an appropriate forming temperature and appropriate drafting multiplying power to realize normal spinning and prepare a dull fiber product with the wool-like effect during spinning, wherein the winding speed of spinning is between 3,800 and 5,200 meters / minute, the shape of a spinning hole of a produced spinning plate comprises a single-line hole arranged along a horizontal direction and at least vertically-arranged vertical holes which are horizontally along the single-line hole and communicated with the single-line hole, the two ends of each vertical hole are respectively provided with a round hole, and the diameter of the round hole is 1.2 to 3 times the width of each vertical hole. The method is applicable for producing the dull fiber with the wool-like effect, and the formed product can have lightless performance and better handfeel.

Description

technical field [0001] The invention relates to a method for manufacturing polyester filaments, in particular to a method for preparing matte fibers with a wool-like effect. Background technique [0002] In recent years, from the viewpoint of protecting the environment and protecting animals, there is a tendency to avoid the use of natural wool, and it has become a current trend to replace natural wool with synthetic fiber products. Among synthetic fibers, polyester is moderately priced and rigid compared to other varieties, but its finished products lack hand feeling. In addition, in the current synthetic fibers, in order to have a dull effect, a matting agent must be added during the preparation process. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing a matt fiber with a wool-like effect without adding a matting agent, and the finished product can have a matt property and a better hand f...
