Problems solved by technology

[0005] However, DTY oil will have adverse effects on the dyeing of fabrics, and it needs to be removed before fabric dyeing, otherwise it will lead to uneven dyeing of fabrics, dull color and poor color fastness
Moreover, dyeing wastewater will be produced during the process of removing DTY oil

Embodiment 1

[0042] This embodiment introduces the production process of the present invention by taking 78dtex / 48f joint stock oil-free PA6DTY as an example.

[0043] The main equipment used in this production process is the joint texturing machine. For the structural diagram of the equipment, please refer to figure 1 .

[0044] Such as figure 1 Shown, under the assistance of this joint texturing machine, the production technology of the present embodiment comprises:

[0045](1) Two strands of raw silk are respectively drawn from the raw silk frame 1, and each is fed into the hot box 4 by a roller 2. The top of the hot box 4 is provided with a twist stopper 3, and the raw silk first passes through the twist stopper 3 and then enters the hot box. Box 4: In the hot box 4, the raw yarn is heated to 170°C and stretched under the action of the second roller 8. The surface line speed of the second roller 8 is 700m / min, the draw ratio is 1.265, and the D / Y ratio is 1.9;

[0046] (2) After be...

Embodiment 78

[0061] Adopt the equipment identical with embodiment 1 to carry out texturing, the production technology of present embodiment 78dtex / 48f joint stock oil-free PA6DTY comprises:

[0062] (1) Two strands of raw silk are respectively drawn from the raw silk frame 1, and each is fed into the hot box 4 by a roller 2. The top of the hot box 4 is provided with a twist stopper 3, and the raw silk first passes through the twist stopper 3 and then enters the hot box. Box 4: In the hot box 4, the raw yarn is heated to 170°C and stretched under the action of the second roller 8. The surface line speed of the second roller 8 is 700m / min, the draw ratio is 1.250, and the D / Y ratio is 1.7;

[0063] (2) After being cooled to 80 DEG C by the cooling plate 5, the two tows heated and stretched enter a false twister 6 respectively for false twist processing;

[0064] The rotating speeds of two false twisters 6 are the same but the twist direction is opposite, thereby obtaining two strands of tow...

Embodiment 3

[0070] Adopt the equipment identical with embodiment 1 to carry out texturing, the production technology of present embodiment 78dtex / 48f joint stock oil-free PA6DTY comprises:

[0071] (1) Two strands of raw silk are respectively drawn from the raw silk frame 1, and each is fed into the hot box 4 by a roller 2. The top of the hot box 4 is provided with a twist stopper 3, and the raw silk first passes through the twist stopper 3 and then enters the hot box. Box 4: In the hot box 4, the raw yarn is heated to 170°C and stretched under the action of the second roller 8. The surface line speed of the second roller 8 is 700m / min, the draw ratio is 1.280, and the D / Y ratio is 1.8;

Abstract

The invention discloses a plied oilless nylon 6 DTY (draw textured yarn), a production technique thereof and a draw-texturing machine to implement the production technique. The production technique comprises (1) heating and drawing two raw yarns; (2) after heating and drawing, cooling, and carrying out false twisting; (3) plying the two false-twisted tows, and winding to obtain a plied oilless nylon 6 DTY, wherein winding tension is 0.05-0.06 times fineness of a finished yarn, and winding overfeed is 3.5-6.5%. The production technique includes no oiling step; since no oiling is performed, towseasily produce static electricity during unwinding, which causes mutual adhesion of strands and end breakage, and also causes poor unwinding performance. In order to overcome such defect of the oilless yarn, the winding tension is set to be 0.05-0.06 times the fineness of the finished yarn, the winding overfeed is set to 3.5-6.5%, and therefore, unwinding performance of the plied oilless nylon 6DTY is improved effectively.

Description

technical field [0001] The invention belongs to the technical field of nylon DTY texturing, and in particular relates to a joint oil-free nylon 6DTY, its production process and a texturing machine for realizing the production process. Background technique [0002] DTY (Draw texturing yarn) refers to drawn textured yarn, which is a finished yarn that is stretched continuously or simultaneously on a texturing machine and deformed by a false twister. DTY generally has low elastic wire, medium elastic wire, high elastic wire, light mesh wire, heavy mesh wire, no mesh wire, low elastic light mesh wire, plied wire, etc. These wire types are based on the network nozzles used in equipment and processes It is determined by the type, the temperature of the first hot box and the second hot box, the type of raw silk, etc. [0003] The processing of DTY is generally carried out on the texturing machine. For joint DTY, the process is generally as follows: two strands of raw silk are resp...
