Embodiment Construction

[0015] It adopts the full-dull polyester chip with titanium dioxide content of 1.5~3% (example 1.5, 1.8, 2.3, 3), after drying (less than 30ppm of moisture), the melt is extruded through the screw extruder, and the screw extruder is provided with 3~ 5 sections of heating zone, the heating temperature of each zone is set between 265 ~ 295 ° C, the melt is accurately metered by the metering pump and distributed to the spinning assembly, and finally passes through the spinning machine with cross-shaped special-shaped spinneret holes and circular spinneret holes The spinneret spits out filaments; the ratio of the number of special-shaped holes to circular holes on the spinneret: special-shaped holes / circular holes = 1 to 2, and the degree of special-shaped holes x 1 =60~95%, the degree of abnormal shape conforms to the following formula:

[0016] x 1 =(1-r 1 / R 1 )×100%,

[0017] where r 1 is the radius of the inscribed circle of the special-shaped hole section, R 1 is the c...

Abstract

The invention discloses a filament of fiber-mixing polyester and the producing method, which is water-absorption, drying quickly, anti-permeable and heteromorphic. The content of titania in the filament of fiber-mixing polyester is 1.5-3%. The filament of fiber-mixing polyester comprises heteromorphic and circle silks. The silk number ratio, namely heteromorphic silk / circle silk, is 1 to 2, the size ration, namely heteromorphic silk / circle silk is 0.8-1.2 and the heteromorphic degree of the silk, x, is 35-55%. The production method contains choosing polyester chip, passing through spinneret and winding the spinning silk. The invention is provided with good water-absorption and drying performance, and good anti-permeable effect. It is also provided with simple producing technology, easy operation so as to ensure the good performance of production.

Description

Technical field: [0001] The invention relates to a blended polyester filament and a manufacturing method thereof. Background technique: [0002] On the one hand, polyester has been widely used in clothing fabrics and other fields due to its excellent physical and chemical properties since its industrial production. Applications in are restricted. Now, as an important indicator for evaluating the comfort and health of clothing fabrics, moisture absorption and perspiration are receiving more and more attention. On the other hand, due to the aggravation of global environmental pollution and man-made destruction, the ecological environment of the earth on which we live and multiply has been seriously damaged. The ozone layer in the atmosphere on the earth has become thinner due to the excessive use of Freon by human beings, which has increased the exposure of ultraviolet rays on the surface of the earth, and the number of human skin cancer patients has increased significantly....
