Example Embodiment

[0010] Specific Embodiment 1: In this embodiment, a hanging drop coating and sizing method for fiber filaments is to pass the fiber filaments through the inside of the hanging drops of the slurry, wherein the fiber collection speed is 0.6-1 m / min.

[0011] In this embodiment, the slurry exists in the form of hanging drops under the interaction of its own surface tension and gravity, and then the fiber filaments are driven by the take-up roller to continuously pass through the interior of the slurry hanging drops, thereby realizing the sizing of the fiber filaments. The amount of slurry required by this embodiment is small, which saves the slurry and reduces the cost, which is 1 / 5 of the amount of slurry required by the existing dipping method.

[0012] In this embodiment, the speed of fiber collection is determined by the properties of the slurry. The fluidity of the slurry is high, and the fiber collection speed is fast. When the fluidity of the slurry is poor, the fiber colle...

Example Embodiment

[0013] Embodiment 2: This embodiment differs from Embodiment 1 in that the fiber collection speed is 0.7-0.9 m / min. Other parameters are the same as in the first embodiment.

[0014] This embodiment can be used to process slurries in ethanol containing 10% by weight epoxy resin.

Example Embodiment

[0015] Embodiment 3: This embodiment differs from Embodiment 1 in that the fiber collection speed is 0.8 m / min. Other parameters are the same as in the first embodiment.

[0016] This embodiment can be used to process slurries in ethanol containing 2% by weight or 5% by weight epoxy resin.

Abstract

The invention discloses a method for sizing fiber filament by coating through hanging drop and used device thereof, relating to a method and device for sizing fiber filament. The invention solves theproblems that the existing fiber filament sizing method needs a large quantity of sizing material and has high cost and the existing sizing device is complex and consumes much energy. The method for sizing fiber filament by dropping includes passing the fiber filament through sizing material drop, wherein the speed for winding fiber is 0.6-1m/min. The used device by the method of the invention comprises a sizing groove, a peristaltic pump, a dropping pipe, a first conveying pipe and a second conveying pipe; one end of the first conveying pipe is extended into a sizing groove to the bottom of the sizing groove, and the other end of the first conveying pipe is communicated with the feeding opening of the peristaltic pump, and the discharging opening of the peristaltic pump is communicated with the feeding opening of the dropping pipe through the second conveying pipe. The method for sizing fiber filament by coating through hanging drop uses a little sizing material, thereby saving sizingmaterial and reducing the cost; and the using amount is 1/5 of the sizing material needed in the existing dipping method. The device of the invention has simple structure and low energy consumption.

Description

technical field [0001] The invention relates to a method and a device for sizing fiber filaments. Background technique [0002] In order to protect the cleanliness of the newly produced fiber surface and avoid absorbing moisture and dust in the air, the manufacturer will set up a sizing process on the production line to perform sizing treatment on the produced fiber, and form a thin layer of protection on the fiber surface after sizing treatment. The film can prevent the fiber from friction, abrasion or hairs during post-processing and use, so as to improve the service life of the fiber. Therefore, existing commercially available fibers are all products after surface sizing treatment. [0003] The existing fiber production line is generally equipped with an online sizing device. After the sizing process, it is dried, and then the product is collected and doffed by a wire receiving machine, and then packaged to enter the market. The existing on-line sizing methods all use t...
