Coating of aramid fibers using the surface treatment agent of the present invention can be done by various methods. In detail, it can be carried out, for example, according to the following methods (a) and (b).

According to method (a), the surface treatment agent is applied onto the undried and unstretched aramid fibers. , and according to method (b), apply the surface treatment agent to the pre-dried aramid fibers. In each case, any known coating equipment is used.

The finish formulation can be used neat or at a low concentration such as 1% by weight. Used in the form of a dilute aqueous solution.

In a route suitable for method (a), about 30 wt. Apply this finishing formulation at a concentration of 30% by weight (this means that 30 parts by weight of the finishing formulation compound + 70 parts by weight of water). Next, this emulsion treated fiber During the fiber drawing and drying stage, the speed of this yarn was increased to approximately 630 m/min (operable range 120-1200 m/min) from 150 to 190°C, preferably about 1 Dry for a few seconds (5-10 seconds) at a temperature of 70°C.

In a preferred route of method (b), the aramid fiber yarns and cords are dip-dressed. Apply it to them by passing it through a dip of the finish formulation in the container. After that, for the untwisted 1670 dtex thread, apply a predetermined tension of 6N. and air heated to 80 to 190°C, preferably 110 to 130°C. Dry in a chamber. The most suitable temperature for this step is about 120°C. The work Dip concentration for raising agent formulations (which range from 1 to 100% by weight in water) Adjust this speed from 15 to 100 m/min depending on 100% workmanship A finish formulation means that this finish does not contain any adulterants. .

Finish levels for both methods (a) and (b) range from 0.05 to 2% by weight. , preferably in the range of 0.2 to 1.0% by weight.

If desired, processes (a) and (b) can also be carried out as a multi-step process. Here, the fiber is dipped into a surface treatment agent several times and dried each time. You may let them. For example, if you apply this treatment onto wet, undried fibers, After drying, the fiber may be dried, and then intermediate drying or drying The surface treatment agent may be applied one or more times without applying the surface treatment agent.

The fibers of the present invention can be used in hoses, belts, lobes, and cables, including optical cables. , rubber products and composite structures (e.g. sporting goods, medical supplies, architecture and Used in reinforcement of acoustic materials, transportation and protection equipment for civil and military applications, etc. It can be done.

In this example, a yarn of 1100 dtex was coated with the finish of the present invention. The same dtex coated aramid fibers are coated with standard finishes. It was compared with a commercially available aramid yarn.

Washability (rinsing properties) is a very important factor because it The residual finish level (measured in %) after which will affect any of the following finishing operations. This is because that. The washability values listed in the table below apply when fabrics made from the yarn of the present invention are used. It is obtained on an industrial scale and treated with standard finishes. The yarn was compared to a control yarn, which is a commercially available product with the same denier. Use soft water at 50℃ These can be removed by washing the yarn twice with 100 mL of water per 10 g of yarn. Values were confirmed in the laboratory.

The coefficient of friction was measured according to the method below. Place the thread from the package into the guide roll and 2 It is driven by a variable motor after passing through a tension device located between the strain gauges of the book. It was passed onto a take-up roll. For these two strain gauges, T1 and T , record the input and output tensions of . This friction coefficient is expressed as %formula%() where a is the friction angle and f is the friction coefficient (polishing fibers and fibres, depending on whether a chrome or ceramic bottle is used. fibers and metals or fibers and ceramics). Follow standard practices known in the art. Therefore, a Rothschild friction meter R-1182 was used.

Deposits due to wear are removed using rStaff-Tester G 555J (Zweigl e, West Germany), and here, it is measured by the friction between fibers. The weight of the worn fiber material was measured.

rG 566J device (Zwei gIe, We""st Germany ) was used to measure the fibril formation index.
