Embodiment 1

[0022] Take 75D / 72F black polyester pre-oriented yarn as (A), and 75D / 72F white polyester pre-oriented yarn as (B).

[0023] Produced on the texturing machine Murata 33H-S+Z machine, the two kinds of raw materials are processed through the normal silk path until the two kinds of silk enter the two silk path weighting networks of the double-groove nozzle chip at the middle roller, and then pass through the lower heat Box shaping, two yarns enter a nozzle at the bottom roller at the same time and increase the air pressure of the network to combine the two yarns into one strand. The preparation process parameters are as follows: vehicle speed 600m / min, draft 1.65, speed ratio 1.70, upper hot box temperature 190°C, lower hot box temperature 185°C, second overrun 3.27%, third overrun 3.49%, middle roller nozzle TG105 (double tank Nozzle), middle roller air pressure 0.4Mpa, bottom roller nozzle TG212, bottom roller network air pressure 0.42Mpa, obtain high-definition two-color DTY c...

Embodiment 2

[0026] Taking 75D / 72F cationic polyester pre-oriented yarn as (A) and 75D / 72F white polyester pre-oriented yarn as (B), the production schematic diagram is as follows figure 1 As shown, the texturizing machine is produced on the Barmag S+Z machine, and the two raw materials are processed in the normal silk path until the two kinds of silk enter a nozzle at the middle roller and increase the network air pressure (install two network pipes) ), and then go through the lower heat box to shape, the two wires enter a nozzle at the bottom roller at the same time and increase the air pressure of the network (add a network pipe), compound the two strands of yarn into one strand. The preparation process parameters are as follows: vehicle speed 550m / min, drafting 1.66, speed ratio 1.82, upper hot box temperature 155°C, lower hot box temperature 135°C, second super-4.0%, third super-4.4%, middle roller nozzle P142, The air pressure of the middle roller is 0.35Mpa, the nozzle of the bottom...

Embodiment 3

[0029] Taking 150D / 48F cationic polyester pre-oriented yarn as (A), and 150D / 96F white polyester pre-oriented yarn as (B), the production schematic diagram is as follows figure 2 As shown, the texturizing machine is produced on the Barmag S+Z machine, and the two raw materials are processed in the normal silk path until the two kinds of silk enter a nozzle at the middle roller and increase the network air pressure (install two network pipes) ), and then go through the lower heat box to shape, the two wires enter a nozzle at the bottom roller at the same time and increase the air pressure of the network (add a network pipe), compound the two strands of yarn into one strand. The preparation process parameters are as follows: vehicle speed 550m / min, drafting 1.66, speed ratio 1.82, upper hot box temperature 155°C, lower hot box temperature 135°C, second super-4.0%, third super-4.4%, middle roller nozzle TG212, The air pressure of the middle roller is 0.35Mpa, the nozzle of the b...

Abstract

The invention relates to the technical field of spinning, and provides a production method for a high-definition dual-color DTY complex fiber. The problem that a high-definition complex fiber cloth cover on the market is turbid in design and color and not good enough in definition is solved. Polyester pre-oriented yarn (A) and (B) can run a normal yarn path on an elasticizer S+Z machine till emphasis network air pressure at a middle roller, and then, polyester pre-oriented yarn (A) and (B) at a lower roller can pass through a nozzle emphasis network air pressure at the same time to compound two filaments. The technology is simple, and the fabric cloth cover is high in definition of design and color.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a production method of a high-definition two-color DTY composite fiber. Background technique [0002] At present, most of the high-definition two-color DTY composite fibers on the market are composed of two heavy-net DTY yarns of different colors or different components, which are compounded by a compound machine to increase the network. And these two kinds of DTY yarns must go through two texturizing processes and then be compounded by compound machine to increase the weight of the network, and its production links are many, and the cost is extremely high. Generally, the conventional silk path is adopted on the S+Z machine of the texturing machine, and a nozzle is added to the middle roller to directly compound the two kinds of silk. Can not achieve the desired effect. Contents of the invention [0003] In order to solve the problems of turbid pattern and insufficient clari...
