In this embodiment, the yarn b is wound by the first linear body spacing ring 2, the first immersion type linear body ring unit 3, the fixing agent a, the second immersion type linear body ring unit 3, the linear body clamping plate unit 4 and the second linear body spacing ring 2 in sequence, so as to finally ensure that the yarn leaving the fixation pretreatment machine has completed the basic fixing agent attaching operation, and the dyeing agent is not easy to drop during the subsequent cloth printing and dyeing.

In addition, a dryer can be arranged between the color fixing pretreatment machine and the warp knitting machine, so that the color fixing agent is properly dried firstly, and then the warp knitting operation is carried out.

In the fixation pre-treatment machine, rotatory stirring board unit 5 is used for guaranteeing everywhere's component homogeneity is good about fixing agent a, avoids the problem that solid phase component sinks the end in a large number in the fixing agent, and below is arranged material pipe 6 and then is used for discharging, retrieves remaining fixing agent after the single is woven.

Immersion type line body ring unit 3 is including leaning on the outer end setting to be in on the box 1 medial surface for the fixation, lean on the transverse installation board 302 that the inner is equipped with ring body groove 301, set up fixed axis body 303 on the ring body groove 301, the cover is in the spacing ring of immersion type 304 of yarn b is walked around to fixed axis body 303 on and below, and set up and be in on the transverse installation board 302 and be used for the installation installing port 305 on the board of line body clamp plate unit 4.

In this embodiment, it is whole that immersion line body ring unit 3 all immerses fixing agent a, guarantees that yarn b can immerse the fixing agent, accomplishes the fixing agent coating effect on the wire rod, and immersion limit ring 304 is unpowered ring, guarantees that yarn b can be smoothly carried to the next stage after the below is walked around can.

The wire body clamping plate unit 4 comprises a vertical mounting plate 401 arranged on the upper surface of the transverse mounting plate 302, an upper fixing plate 402 arranged on the side surface of the vertical mounting plate 401 and located above the upper mounting port 305 of the plate and used for pressing down yarns when extruding redundant fixing agents of the yarns, and an inserted electric heating plate part 403 arranged on the upper mounting port 305 of the plate and used for clamping the yarns b by matching with the upper fixing plate 402 in a mode of upwards jacking through buoyancy. The plug-in electric heating plate part 403 comprises a vertical heating plate 403a, a heat insulation plate 403b, a heating wire 403c, a lower movable plate 403d and a floating block 403e, wherein the vertical heating plate 403a is inserted into the installation opening 305 on the plate, the heating wire 403a is arranged on the upper end face of the vertical heating plate 403a, the heating wire 403c is externally connected with a power supply, the lower movable plate 403d is arranged on the upper end face of the heat insulation plate 403b and used for clamping the yarns b upwards, and the floating block 403e is arranged on the vertical heating plate 403a, is located in the color fixing agent a and used for increasing the pressure of the lower movable plate 403d for clamping the yarns b. The side surface of the lower movable plate 403d close to the immersion type position-limiting ring 304 is located above the ring body groove 301 to drop the excessive extruded fixing agent back into the ring body groove 301.

In the present embodiment, the wire body clamping plate unit 4 has two functions.

First, the material of floating block 403e is current light plastics, guarantees to float in fixing agent a, like this below fly leaf 403d has an upward jack-up trend, can with top fixed plate 402 presss from both sides the yarn that has coated the fixing agent together, extrudes unnecessary fixing agent in the yarn, guarantees on-line enough and suitable fixing agent quantity.
