Problems solved by technology

[0007] However, the optimization of dyeing liquor mostly depends on adding new chemical auxiliaries such as leveling agent and penetrating agent. The introduction of too many chemical auxiliaries may cause the disorder of the dyeing liquor system, destroy the molecular structure of fibers, and increase the burden of subsequent wastewater treatment. Burden; process parameters such as dyeing temperature increase, on the one hand consume more energy; on the other hand, in actual operation, it is difficult to control

Embodiment 1

[0046] Such as Figure 1-2 As shown, this embodiment discloses a tube dyeing device for chemical fiber yarn, which includes a dyeing vat 1, a vat cover 2, a winding frame 3, and a heating device. The winding frame 3 can be placed in the dye vat 1, the vat 2 is closed on the dye vat 1, and the heating device is used to heat the dye vat 1.

[0047] The dye vat 1 includes a feed end 111 and a discharge end 112; both of the feed end 111 and the discharge end 112 are provided with valves. The heating device of the present invention is a heating device of the prior art, preferably a heating tube arranged on the dye vat 1 .

[0048] The winding frame 3 includes a chassis 31 , a first support round bar 32 , a second support round bar 33 , a yarn passage tube 34 , a first motor 35 , and a second motor 36 . The bottom of the first support round bar 32 and the bottom of the second support round bar 33 are all rotatably connected with the chassis 31, and the tops of the first support ro...

Embodiment 2

[0066] The present invention also provides a method for tube dyeing aramid fibers using the above chemical fiber yarn tube dyeing device, comprising the following steps:

[0067] (1) Pretreat the aramid yarn after winding: at 80°C, place the aramid yarn in the treatment solution with a bath ratio of 1:20, boil for 40 minutes, and then dry. The treatment solution includes the following raw materials in parts by mass: 2 parts of urea, 3 parts of triphosphite, 4 parts of non-phosphorus neutral degreasing spirit TF-104M, and 900 parts of water.

[0068] (2) Set the aramid yarn wound after pretreatment in the first support rod 32 , and place the yarn tube 37 in the second support rod 33 . The joint of the aramid yarn wound in the first support rod 32 is introduced into the corresponding yarn tube 37 in the second support rod 33 through the yarn channel tube 34 and fixed on the yarn tube 37 .

[0069] (3) Add cationic dye solution into dye vat 1, and the bath ratio of yarn to dye s...

Embodiment 3

[0074] The aramid yarn dyed by the method of Example 2 was tested for color fastness, and the results are shown in Table 1, wherein the cationic dyes are cationic blue X-GRRL, cationic blue X-BL, and cationic red X-GTL.

[0075] Table 1

[0076]

[0077] It can be seen from Table 1 that the color fastness of the aramid yarn prepared by the method of the present invention can basically be maintained at level 5.

Abstract

The invention discloses a chemical fiber yarn tube dyeing device. The device comprises a dyeing cylinder, a cylinder cover, a bobbin frame and a heating device; the bobbin frame can be placed into thedyeing cylinder, the cylinder cover covers the dyeing cylinder, and the heating device is used for heating the dyeing cylinder; the bobbin frame comprises a chassis, a first supporting circular rod,a second supporting circular rod, a yarn channel pipe, a first motor and a second motor; the bottom of the first supporting circular rod and the bottom of the second supporting circular rod are both rotatably connected with the chassis, the top of the first supporting circular rod and the top of the second supporting circular rod both extend upwards vertically, and a yarn pipe is sleeved with a second supporting pipe; the yarn channel pipe is arranged between the first supporting circular rod and the second supporting circular rod; the first motor is connected with the first supporting circular rod, and the second motor is connected with the second supporting circular rod. The invention further discloses a method for using the chemical fiber yarn tube dyeing device to achieve bobbing dyeing of aramid yarn. The chemical fiber yarn tube dyeing device and the method for using the chemical fiber yarn tube dyeing device to achieve bobbing dyeing of the aramid yarn have the advantages that the mobility of the yarn in the dyeing cylinder is improved, and the contact degree between the yarn and dye is increased.

Description

technical field [0001] The invention relates to the technical field of textile products, in particular to a tube dyeing device for chemical fiber yarn and a method for tube dyeing aramid yarn with the device. Background technique [0002] The full name of aramid fiber is "polyphthalamide phenylene diamide", which is Aramid fiber in English (the trade name of Teijin Aramid is Twaron and DuPont's trade name is Kevlar). It is a new type of high-tech synthetic fiber with ultra-high strength. , high modulus and high temperature resistance, acid and alkali resistance, light weight and other excellent properties, its strength is 5 to 6 times that of steel wire, its modulus is 2 to 3 times that of steel wire or glass fiber, its toughness is 2 times that of steel wire, and its weight is It is only about 1 / 5 of the steel wire, and it does not decompose or melt at a temperature of 560 degrees. It has good insulation and anti-aging performance, and has a long life cycle. The discovery...
