Description

Technical Field

[0001] This invention relates to the field of fabric textiles, and in particular to an online multicolor ply yarn production apparatus and method for DTY. Background Technology

[0002] DTY (polyester low elasticity yarn) is a type of textured yarn of polyester chemical fiber. It is made from polyester chips (PET) as raw material, using high-speed spinning of polyester pre-oriented yarn (POY), and then processed by drawing and false twisting. It has the characteristics of short process, high efficiency and good quality.

[0003] DTY multicolor yarn is a common DTY product. Its preparation method is to re-strand multiple DTY colored yarns (single color) to obtain DTY multicolor yarn with multiple colors.

[0004] Traditional DTY multicolor yarn production methods mostly use cationic polyester or heather gray DTY, which requires cationic / black POY and ordinary POY, which are plied together. Cationic polyester needs to be dyed (single dyeing or double dyeing) to bring out the pattern and style of the fabric, which requires the use of multiple different types of POY (cationic POY, black POY), and then dyed again after pliing. The raw material cost is high; moreover, the dyeing process is long and generates a lot of energy, resulting in high production costs. Summary of the Invention

[0005] The purpose of this invention is to provide an online multi-color ply yarn production apparatus and method for DTY. This invention completes multi-color coloring and plying during the DTY production process, offering advantages such as low raw material costs, simple process, and energy savings.

[0006] The technical solution of the present invention is as follows: A DTY online multi-color ply yarn production device, comprising a texturing machine for processing POY, a multi-color coloring unit and a ply yarn generator disposed on the texturing machine; the multi-color coloring unit is disposed between the raw yarn frame and the yarn cutter of the texturing machine; the ply yarn generator is located between the second roller and the network nozzle of the texturing machine; the POY is fed into the texturing machine from the raw yarn frame for processing, colored by the multi-color coloring unit and ply yarn by the ply yarn generator, and finally fed into the winding frame for winding into a cylinder.

[0009] In the aforementioned DTY online multicolor ply yarn production device, the dye liquor replenishment unit includes a dye liquor unit A located on one side of the two-color liquid tank and connected to liquid tank A, and a dye liquor unit B located on the other side of the two-color liquid tank and connected to liquid tank B. The dye liquor unit A includes a dispensing tank A, a storage tank A, a delivery pump A, an inlet pipe A, and a return pipe A. The bottom of the dispensing tank A is connected to the top of the storage tank A via a delivery pipe with a valve. One end of the inlet pipe is located at the bottom of the storage tank A, and the other end is located above the beginning of liquid tank A. The delivery pump A is located on the inlet pipe A. One end of the return pipe A is located at the top of the storage tank A, and the other end is connected to the bottom of the end of liquid tank A.

[0010] In the aforementioned DTY online multicolor ply yarn production device, the structure of the dyeing solution unit B is similar to that of the dyeing solution unit A. The dyeing solution unit B includes a dispensing tank B, a storage tank B, a transfer pump B, an inlet pipe B, and a return pipe B. One end of the inlet pipe B is located at the bottom of the storage tank B, and the other end is located above the tail end of the B liquid tank. One end of the return pipe B is located at the top of the storage tank B, and the other end is connected to the bottom of the head end of the B liquid tank. The inlet pipe A and the inlet pipe B are connected by a bypass valve.

[0011] In the aforementioned DTY online multicolor ply yarn production device, the multicolor coloring unit is a multi-tank immersion coloring unit; the multi-tank immersion coloring unit includes a multicolor tank for coloring, multiple guide yarn units evenly distributed within the multicolor tank, a dye liquor within the multicolor tank, and a dye liquor replenishment unit connected to the multicolor tank; multiple dyeing tanks are arranged side by side within the multicolor tank, and each dyeing tank is provided with a corresponding dye liquor replenishment unit; the guide yarn units are evenly distributed on the dyeing tank, and the guide yarn units on adjacent dyeing tanks are staggered; each guide yarn unit includes a pair of inverted guide yarns immersed in the dye liquor, and a pair of upright guide yarns correspondingly provided on the tank wall of the dyeing tank; the POY passes through the guide yarn units for coloring.

[0012] In the aforementioned DTY online multi-color ply yarn production device, each dyeing tank has an inlet on the upper left side and a reflux outlet on the bottom right side; each dye liquor replenishment unit includes a dispensing tank and a storage tank; the bottom of the dispensing tank is connected to the top of the storage tank via a delivery pipe with a control valve; the storage tank is connected to the inlet via an inlet pipe with a delivery pump; and the reflux outlet is connected to the bottom of the storage tank via a reflux pipe.

[0013] A method for producing DTY online multicolor ply yarn, wherein POY is colored by a multicolor coloring unit when it enters the texturing machine, and the colored POY is fixed in color during the processing and then ply by a plying device to obtain multicolor ply DTY.

[0014] In the aforementioned online multi-color ply yarn production method for DTY, the processing of POY in the texturing machine is as follows:

[0015] A. Prepare the dye solution and add multicolor coloring units;

[0016] B. POY is colored from the original yarn frame through a multi-color coloring unit;

[0017] C. After coloring, the POY is sent to the first hot box after passing through the first roller for stretching, deformation and drying to fix the color.

[0018] D. After color fixing, the POY is sequentially passed through a cooling plate, false twister, second roller, strander and network nozzle for stranding;

[0019] E. After being combined, the mixture enters the second hot box for shaping and color fixing;

[0020] F. After passing through the third roller and the upper oil tanker, it is wound into a DTY cylinder on the winding frame tube.

[0021] Compared with the prior art, the present invention provides a DTY online multi-color ply yarn production device and method. Before entering the device for texturing, the white POY is colored by a multi-color coloring unit, so that it can be fixed during the processing to produce multi-color ply DTY products.

[0022] This invention utilizes the low crystallinity of POY, which allows dye particles to easily penetrate and be adsorbed. After the natural white POY passes through a multi-color coloring unit, it is stretched and deformed in the hot box of a texturing machine, which changes the molecular chain and simultaneously dries and fixes the colored filaments. After being twisted (double-strand, triple-strand, quadruple-strand), multi-color twisted DTY (two-color + natural white or three-color + natural white) is obtained.

[0023] The production of multi-color twisted DTY using this invention does not require re-twisting or other processing; it can be completed directly during the production of DTY from white POY, resulting in low production costs and high production efficiency.

[0024] Using this invention for production, only ordinary POY can be used to complete the process directly during DTY production, resulting in low raw material costs and eliminating the need for subsequent dyeing procedures.

[0025] The multi-color ply DTY produced by this invention is used to weave greige fabric. During the finishing process, the fabric only needs to be tumbled into the dyeing vat at the temperature required for fabric shrinkage. This eliminates the need for high pressure and high temperature, and saves dyeing time (traditional greige fabric requires dyeing for about 30 minutes at a temperature of about 130°C, followed by heat preservation and other processes). This significantly saves energy and improves production efficiency.

[0026] There is a price difference between natural white POY and cationic and colored POY. Moreover, colored POY comes in many colors. Traditional production is not only troublesome but also costly. However, by using this application for production, only natural white POY is needed to achieve the desired purpose. This not only simplifies the process but also saves costs.

[0027] Therefore, this invention, by completing multi-color coloring and plying during the DTY production process, has the advantages of low raw material cost, simple process, and energy saving. Attached Figure Description
