Problems solved by technology

[0002] Currently on the market, the cross-sectional shape of the different shrinkage network composite yarn is circular, that is, the cross-section shape of the POY, FDY or UDY produced by the previous spinning is circular. This different shrinkage network composite yarn is knitted and woven downstream. There are defects that cannot be completely solved among users, such as sandwich monofilament, sandwich three-wire, white strip silk, etc., which can only be used for medium and low-end products

Embodiment

[0009] Embodiment: A kind of different shrinkage two-component network composite yarn, which is composed of pre-oriented yarn 1 and fully drawn yarn 2. The pre-oriented yarn is composed of 8 to 144 filament fibers, and the cross-section of the pre-oriented yarn is It is in the shape of "rice", the fully drawn yarn is composed of 8 to 96 filament fibers, and the cross section of the fully drawn yarn is in the shape of "ten".

[0010] The production process of this example is as follows:

[0011] Pre-oriented yarn (POY) and fully drawn yarn (FDY) are obtained by drying the raw material, melting the screw, discharging the wire from the assembly, cooling by side air blowing and drawing by the godet;

[0012] In the process of producing pre-oriented filament 1, the components used in the component filament discharge link have a "meter"-shaped hole on the spinneret; in the process of producing fully drawn filament 2, the components used in the component filament discharge link The ...

Abstract

The invention discloses a different shrinkage two-component network composite filament, which consists of a pre-oriented yarn and a fully draw yarn, the pre-oriented yarn is composed of 8-144 filament fibers, and the section of the pre-oriented yarn is shaped like a Chinese character Mi, and the fully draw yarn is composed of 8-96 filament fibers, and the section of the fully draw yarn is cross-shaped, and the embodiment has good evenness on running thread and uniform dyeing, and has effects of moisture absorption and perspiration.

Description

technical field [0001] The invention relates to spinning, in particular to a different shrinkage network composite yarn capable of absorbing moisture and releasing sweat. Background technique [0002] Currently on the market, the cross-sectional shape of the different shrinkage network composite yarn is circular, that is, the cross-section shape of the POY, FDY or UDY produced by the previous spinning is circular, and the different shrinkage network composite yarn is knitted and woven downstream. There are defects that cannot be completely solved among users, such as sandwich monofilament, sandwich three-wire, white strip silk, etc., which can only be used for medium and low-end products. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a different-shrinkage two-component network composite yarn, which is uniform in dryness, uniform in dyeing, and has the effects of moisture absorption and perspiration. [...
