Problems solved by technology

However, this method requires three kinds of fiber materials to achieve three colors, and the cost is high; and the fibers need to be treated with alkali, and then undergo cationic dyeing and disperse dyeing respectively to present a three-color shape. The preparation process is relatively complicated, which is not conducive to large-scale mass production.

Embodiment 1

[0032] A preparation method of polyester-yang tricolor polyester filament, comprising the following steps:

[0033] Polyester bright semi-oriented silk MOY is produced by spinning, with a specification of 130dtex / 48f, a strength of 1.8cn / dtex, and an elongation of 160%. Cationic FDY specifications are 55dtex / 48f, a strength of 3.0cn / dtex, and an elongation of 20%.

[0034] Such as figure 1 As shown, the polyester bright semi-oriented yarn MOY is successively transmitted to the first roller 5 through the zero roller 1, the first yarn guide 2, the second yarn guide 3 and the third yarn guide 4; wherein, in the first A heat roller 6 is arranged between the yarn guide and the second yarn guide, and a reciprocating pull rod 7 is installed on the second yarn guide, and the reciprocating pull rod can drive the second yarn guide to swing back and forth along the direction perpendicular to the silk path, so as to The polyester bright semi-oriented yarn MOY is intermittently heated by ...

Embodiment 2

[0041] A preparation method of polyester-yang tricolor polyester filament, comprising the following steps:

[0042] Polyester semi-oriented yarn MOY is obtained by spinning, with a specification of 220dtex / 72f, a strength of 1.85cn / dtex, and an elongation of 165%, and a cationic FDY specification of 83dtex / 72f, with a strength of 3.1cn / dtex, and an elongation of 22%.

[0043]The polyester bright semi-oriented yarn MOY is transmitted to the first roller 5 through the zero roller 1, the first yarn guide 2, the second yarn guide 3 and the third yarn guide 4 in sequence; A hot roller 6 is arranged between the second yarn guide and a reciprocating pull rod 7 is installed on the second yarn guide. The reciprocating pull rod can drive the second yarn guide to swing back and forth along the direction perpendicular to the silk path, so that the polyester The bright semi-oriented yarn MOY is intermittently heated by hot rollers.

Abstract

The invention relates to the field of chemical fibers, and discloses a preparation method of cationic polyester tricolor polyester filaments. The method comprises the steps that 1, MOY is transmittedto a roller one by passing through a roller zero, a first yarn guide, a second yard guide and a third yarn guide in sequence, a hot roller is arranged between the first yarn guide and the second yarnguide, and a reciprocating pull rod is arranged on the second yarn guide; 2, FDY is mixed with the MOY at the roller one, deformation, cooling, false twisting, network compositing, drafting, sizing, conveying and winding are conducted in sequence subsequently, and the cationic polyester tricolor polyester filaments are obtained. Accordingly, two kinds of fibers serve as the raw materials, a fabricwoven through the cationic polyester tricolor polyester filaments is subjected to deep dyeing easily after being dyed through single dye, and the fabric has the tricolor space dye effect; meanwhile,the dyeing cost is reduced, the color is bright, and wearing is comfortable.

Description

technical field [0001] The invention relates to the field of chemical fibers, in particular to a preparation method of polyester-yang tricolor polyester filaments. Background technique [0002] Generally, in the materials of women's clothing, fabrics with various colors are always selected, and the colorful effect is mainly achieved through dyeing. Therefore, the cost of dyeing is much higher than that of single dyeing. With the vigorous rectification of printing and dyeing enterprises by environmental protection, more and more unqualified printing and dyeing enterprises have been shut down, resulting in an increase in the cost of fabric dyeing, and the downstream garment enterprises have become increasingly difficult to operate. Therefore develop a kind of dyeing cost is cheap, the polyester fiber of easy deep dyeing has huge market space. [0003] The Chinese patent with the application number 200510042114.3 discloses a method for manufacturing three-color different-dyein...
