Embodiment 1

[0025] Embodiment 1: the cross-shaped atmospheric pressure cationic dyeable ice-cool polyester fiber of this example, the cross-section of the fiber is cross-shaped, and the content of its mica powder is 0.8%, and the rest is normal pressure cationic dyeable polyester, the monofilament of the fiber The fineness is 1.33dtex.

[0026] The preparation method is as follows: firstly mix mica powder and ECDP at a mass ratio of 20:80, and then granulate through a twin-screw extruder to prepare cold masterbatch.

[0027] Then dry cold masterbatch and ECDP are melt-blended and spun with a mass ratio of 4:96, and sprayed out through a cross-shaped spinneret, wherein such as figure 1 , the spinneret hole length a is 0.6mm, the blade width b is 0.10mm, and then cooled by blowing, stretched, shaped, cut and packaged to form a cross-shaped atmospheric pressure cationic dyeable cold polyester fiber. Its main process parameters are as follows: spinning temperature is 278~290°C, cooling blowi...

Embodiment 2

[0028] Embodiment 2: The cross-shaped atmospheric pressure cationic dyeable ice-cold polyester fiber of this example, the cross section of the fiber is cross-shaped, the content of its mica powder is 1.0%, the rest is normal pressure cationic dyeable polyester, the monofilament of the fiber The fineness is 1.33dtex.

[0029] The preparation method is as follows: firstly mix mica powder and ECDP at a mass ratio of 20:80, and then granulate through a twin-screw extruder to prepare cold masterbatch.

[0030] Then dry cold masterbatch and ECDP are melt-blended and spun with a mass ratio of 5:95, and sprayed out through a cross-shaped spinneret, wherein such as figure 1 , The length a of the spinneret hole is 0.6mm, and the leaf width b is 0.10mm, and then air-cooled, stretched, shaped, cut and packaged to form a cross-shaped normal-pressure cationic dyeable cold polyester fiber. The main process parameters are as follows: spinning temperature is 278~290°C, cooling blowing wind sp...

Embodiment 3

[0031] Embodiment 3: the cross-shaped atmospheric pressure cationic dyeable cold polyester fiber of this example, the cross-section of the fiber is cross-shaped, and the content of its mica powder is 1.5%, and the rest is normal pressure cationic dyeable polyester, the monofilament of the fiber The fineness is 1.33dtex.

[0032] The preparation method is as follows: firstly, mica powder and ECDP sheet are mixed at a mass ratio of 15:85, and then granulated by a twin-screw extruder to prepare cold masterbatch.

[0033] Then dry cold masterbatch and ECDP are melt-blended and spun with a mass ratio of 10:90, and sprayed out through a cross-shaped spinneret, wherein such as figure 1 , the spinneret hole length a is 0.6mm, the blade width b is 0.10mm, and then cooled by blowing, stretched, shaped, cut and packaged to form a cross-shaped atmospheric pressure cationic dyeable cold polyester fiber. Its main process parameters are as follows: spinning temperature is 278~290°C, cooling...

Abstract

The invention provides a cross cool easy cation-dyeable polyester (ECDP) fiber and a production method thereof. The production method comprises the following steps: carrying out melt blended spinning on cool master batches of mica and ECDP, spurting the silk by a cross spinneret plate, ensuring the silk to enter into a pre-drawing machine to be pre-drawn after the silk is aired and cooled, then ensuring the tows to enter into a tow collecting barrel to be set and then carrying out cutting off and packing, thus obtaining the cross cool ECDP fiber. The fiber and the production method have the following beneficial effects: the garment fabric made of the fiber not only has the functions of absorbing moisture and cooling but also has the ECD characteristic; and the subsequent dyeing cost is saved; and the fiber can be independently spun and also can be blended with other products, is suitable for development of sportswear and undergarments and has good comfortableness and health care property.

Description

technical field [0001] The invention relates to the technical field of chemical fibers, in particular to a cross-shaped atmospheric pressure cationic dyeable cool polyester fiber and a manufacturing method thereof. Background technique [0002] With the gradual warming of the earth's climate, people have gradually paid attention to functional fabrics. Especially in the hot and humid summer, people wish to wear some cool moisture-absorbing and quick-drying clothes to reduce the requirement of the human body to the ambient temperature. At the same time, with the continuous improvement of people's living standards, people's health requirements for clothing are also getting higher and higher, not only in pursuit of clothing comfort, beauty and novelty, but also require clothing to have some other functions, such as moisture absorption and perspiration, anti-ultraviolet , cool and other functions. [0003] Chinese patent CN101067227A discloses a "cool silk". The feature of thi...
