preparation example Construction

[0058] A preparation method of polyester multifunctional fancy yarn, comprising the following steps:

[0059] 1) The cationic MOY wire is fed through the zero roller, and under the action of the reciprocating swing of the pendulum rod, it is heated intermittently by the hot roller, and then enters the first roller. Draft ratio DR of cationic MOY yarn between zero roller and one roller 01 is 1.55-1.65.

[0060] 2) At the same time, the two kinds of fine denier porous flame-retardant POY yarns are pre-networked first, and then fed into one roller after being fed by another zero roller. Draft ratio DR of fine denier porous flame retardant POY yarn between zero roller and one roller 02 is 0.98-1.0.

[0061] 3) The cationic MOY yarn, the fine denier porous flame-retardant POY yarn and the fully matte FDY yarn meet at one roller, and the main draft DR is 1.05-1.1. Then, after drawing, texturing (200-220°C), cooling, false twisting, network compounding, setting (180-200°C), and w...

Embodiment 1

[0064] The cationic MOY yarn was obtained by spinning, with a specification of 273dtex / 48f, a breaking strength of 1.75 cn / dtex, and an elongation at break of 175%; the full extinction FDY yarn with a specification of 167 dtex / 72f, a breaking strength of 3.1cn / dtex, and an elongation at break of 27 %; fine denier porous flame-retardant POY yarn, phosphorus content is 6600ppm, specifications are 365 dtex / 288 f, 142 dtex / 144f, the former has a breaking strength of 2.05 cn / dtex and a breaking elongation of 128%; the latter has a breaking strength of 2.03 cn / dtex, elongation at break 125%.

[0065] The cationic MOY yarn passes through the zero roller, under the action of the reciprocating pendulum rod, it is heated by the hot roller intermittently, and passes through another zero roller with the other two specifications of fine denier porous flame-retardant POY yarn without drafting and full extinction. The FDY yarns meet at a roller, and are successively drawn, deformed, coole...

Embodiment 2

[0069] The cationic MOY yarn was obtained by spinning, with a specification of 205dtex / 48f, a breaking strength of 1.70 cn / dtex, an elongation at break of 180%, and a full extinction FDY yarn with a specification of 111 dtex / 72f, a strength of 3.3cn / dtex, and an elongation of 25%. Fine denier porous flame-retardant POY yarn, phosphorus content is 6600ppm, specifications are 270dtex / 288f, 142dtex / 144f, the former has a breaking strength of 2.08cn / dtex and an elongation at break of 126%; the latter has a breaking strength of 2.03cn / dtex, Elongation at break 125%.

[0070] In Example 2, the fine denier porous flame-retardant POY yarn, cationic MOY yarn and fully matte FDY yarn are all prepared by using polyester chips as raw materials, extruding and spinning by twin-screw. The preparation method of polyester chips is:

[0071] Preparation of silicon-titanium composite homogeneous catalyst: add 74.4g (1.2mol) ethylene glycol to a 500ml flask equipped with a magnetic stirring an...

Abstract

The invention relates to the textile field, and discloses terylene multifunctional fancy yarns and a preparation method thereof. The yarns are compounded by four different spinning yarns which separately include two micro-thin porous flame-retardant POY yarns in different specifications, a cation MOY yarn and a complete extinction FDY yarn. The yarns have soft wool feeling and unique style. The light shading property of the prepared product is excellent, a perspective prevention effect is good, the layering sense is high, a permanent flame-retardant effect is achieved, and the terylene multifunctional fancy yarns can be mainly suitable for the fields of carpets, curtains, decorative cloth and the like.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a polyester multifunctional fancy yarn and a preparation method thereof. Background technique [0002] With the increasing improvement of people's living standards, both the needs of life and the needs of decoration have provided a broad world for the development of home textiles. [0003] At present, in the home textile industry, ordinary polyester or natural fibers are mostly used. The fabrics woven with the above fibers are less comfortable, single in style and expensive. Focusing on this, we have developed a style that is comfortable to the touch, affordable, and has various styles. Multifunctional fancy yarn with broad market prospects. [0004] The Chinese patent with application number 201620785506.2 discloses a fancy yarn, the utility model includes a core yarn and an outer yarn, the core yarn includes cotton yarn, polyester yarn and hemp yarn, and the outer yarn includes woven c...
