Definitions

• the invention pertains to a finish composition for treating yarns and to yarns comprising said finish composition.
• yarns are commonly treated with a finish or coating.
• Such treated yarns also called fibers or threads, may show improved breaking strength, coefficient of friction, wear, fatigue, antistatic properties, and the like.
• European patent application No. 0 474 467 to Griffin teaches a liquid composition comprising a silicone oil, a wax emulsion, and a silicone surfactant. This liquid composition can be applied to yarns. This composition can easily be applied using kiss roll methods without corroding or otherwise destroying the application equipment. However, this composition does not lead to improved wear and fatigue properties.
• There is a need to improve the wear and fatigue properties of yarns preferably by applying a suitable finish. This need is felt especially when yarns are wet, as is usually the case in the offshore and marine industry.
• the invention pertains to a finish composition for treating yarns comprising a mixture of silicone oil emulsion and a wax emulsion wherein the amount of silicone oil is 0.5 to 30 wt.%, the amount of wax is 1.5 to 45 wt.%, the total of silicone oil and wax is 2 to 60 wt.%, and the ratio silicone oil:wax is ⁇ 1. These wt.% are based on the total ingredients, including water, of the finish composition. It was found that these finish compositions, when applied on yarns, considerably improve their wear and fatigue properties. The invention therefore also pertains to yarns comprising the above-mentioned finish composition.
• the amount of silicone oil is 1 to 10 wt.%, the amount of wax is 3 to 25 wt.%, the total of silicone oil and wax is 4 to 35 wt.%, and the ratio silicone oil:wax is ⁇ 1. More preferably, the amount of silicone oil is 2 to 4 wt.%, the amount of wax is 6 to 12 wt.%, the total of silicone oil and wax is 8 to 16 wt.%.
• the silicone oil is emulsified in water.
• the silicone oil of the invention may be any suitable silicone oil that can be emulsified in water.
• the silicone oil has a viscosity of 1 ,000 to 1 ,000,000 centistokes at 25°C, more preferably 10,000 to 300,000 centistokes.
• Preferred silicone oils are polyalkylsiloxanes, polyetheralkylsiloxanes, and mixtures thereof.
• Polyalkylsiloxane emulsions are commercially available, for instance the polydimethylsiloxane emulsion Tego Emulsion HOTM (ex Hansa Textil Chemie GmbH).
• the silicone oil emulsion has a viscosity of 10 to 500 centistokes at 25°C.
• the wax component in the finish composition is not very critical, and in principle any suitable wax can be used, such as petroleum waxes, polyethylene waxes, Fischer-Tropsch waxes, and natural waxes.
• Preferred waxes are selected from paraffin wax, camauba wax, montan wax, and oxidized polyethylene wax.
• the waxes are used in an emulsion in water comprising 10 to 80 wt.% of the wax, preferably 30-60 wt.%.
• the finish may comprise auxiliary compounds commonly present in finishes, such as surfactants.
• Suitable surfactants are silicone surfactants, for instance polydiorganosiloxane-polyoxyalkene copolymers, which are known in the art.
• the finish can be applied onto the yarn in an amount of 4 to 50 wt.%, preferably between 4 and 35 wt.%, and more preferably between 8 and 16 wt.%.
• the finish can be used for any type of yarn, such as polyester yarn, polyamide yarn, polyurethane yam, aramid yarn, polyethylene yarn, and the like. Most preferably, the finish is applied onto aramid yarn.
• the most common aramid yarn is made of PPTA polymer and is available as Twaron® (ex Twaron Products), Kevlar® (ex DuPont), or Technora® (ex Teijin). The finish is applied onto the yarn by methods known to a person of ordinary skill.
• a suitable method is, e.g., the application via a kiss roll, a finish bath, or a liquid applicator.
• the finish can be applied onto the yarn as a combined emulsion comprising both the wax and silicone oil emulsions, or in a two-step process wherein first the wax emulsion is applied onto the yarn and then dried, followed by the application of the silicone oil emulsion onto the yarn, optionally followed by a drying step.
• a finish according to the invention (F1 ), a finish for comparison (F2), and a finish according to Example 2 of EP 0 474 467 (F3, reference) were prepared using as the wax a 40 wt.% emulsion of Aquacer 533TM (ex BYK-Cera bv; W1 ) or a 48 wt.% emulsion of Rayolan CPNTM (ex B ⁇ hme; W2), and as the silicone oil a 40 wt.% emulsion of Hansa Lub HOTM (ex Hansa Textil Chemie GmbH; S1 ), pure Wacker AK50TM (ex Wacker; S2), or pure Silwet Surfactant L7602TM (ex Union Carbide; S3).
• a finish comprising the wax emulsion without the silicone oil emulsion (Fw) and a finish comprising the silicone oil emulsion without the wax emulsion (Fs) were used. These finishes are denoted in Table 1 (in parts of components other than water).
• Twaron® 1010, 1680 dtex (ex Twaron Products) yarn was treated with finishes F1 and F2 before entering a steam box, using a liquid applicator consisting of a ceramic pin and a dosing pump before the heating section.
• the finished yarn was heated at 200°C in the 10 m long steam box. Its residence time was 8 sec.
• the finishes were applied onto the yarn in amounts of 5 or 12 wt.% Finish F3 was rather unstable and had to be stirred before application.
• This finish was applied onto the same Twaron feed yarn using a ceramic pin and a laboratory dosage injector.
• the finished yarn was not dried in the steam box.
• the finish was applied onto the yarn in an amount of 5%.
• Finishes Fw and Fs were applied onto the yarn in the same manner as finishes F1 and F2, in an amount of 5 and 3 wt.%, respectively.
• Finish F4 was obtained by first applying 5 wt.% Fw onto the yarn and drying the yarn, followed by applying 3 wt.% Fs, after which the yarn was not dried further in the steam box. The total amount of finish on the yarn was 8 wt.%.
• the yarns were tested for their wet abrasion properties using the Flory test (Flory et al., Abrasion Resistance of Polymeric Fibers in Marine Conditions. Proceedings 2 nd International Conference on Polymers in a Marine Environment. London, 1989, pp. 197-204).
• a 20 mm and a 35 mm top pulley, and a 20 mm lower pulley were used.
• the distance between the top pulleys was 10 cm instead of 14 cm.
• the tension weight was 40 mN/tex and the length of the strokes was 48 mm instead of 50 mm.
• the wet bending fatigue properties were determined in the Alma test (Fig. I).
• the yarn was cabled to a cord of 1680 dtex X 7, Z30.
• the cord having a theoretical cord diameter of 1.22 mm was fixed over three 40 mm pulleys according to the figure, and loaded with a weight of 10% of the initial cord breaking strength (21 kg).
• the cord was continuously wetted with tap water.
• cords made of finished yarns obtained by the application of an emulsion comprising both silicone oil and wax leads to results comparable to those for cords made of yarns obtained in a two-step process with the application of a wax emulsion being followed by the application of a silicone oil emulsion (F5/F6).
