Chemicals for maximum process reliability – Primary Spinning
Friction and heat that occur in yarn production and processing are the natural enemies of any synthetic fiber. They have to be kept under control. Spin finishes from Pulcra Chemicals absorb frictional heat, prevent electrostatic charging, ensure perfect cohesion of the sensitive filaments, and wrap every yarn reliably around the bobbin – at drawing off speeds of 1,000 to 6,000 meters per minute.
Evolution of the synthetic fiber
Synthetic fibers have become a significant player in the textile market, finding uses in apparel, home furnishings, and technical applications. The fact that polyamide, polyester, and the like display many of the advantages of natural fibers – and quite a few more besides – can be attributed in part to high-performance spin finishes. They ensure that industrial and technical polyester yarns will not break under extreme processing conditions and give fine nylon yarns the smoothness they need for high-speed processing into elastic hosiery.
Extensive know-how for products that meet market needs
Dozens of different processes create very diverse requirement profiles. We design our spin finish formulations to have the precise properties needed for each processing step. Very fine yarns have to slide more smoothly than technical yarns, while only moderate sliding properties are required for twisting. In texturizing, the yarn is made voluminous and elastic by thermo-mechanical treatment, and the goals in drawing are strength and resistance. In this process the yarn is almost melted by the high processing temperatures. Here, the lubricant must protect the fragile yarn as well as not evaporate, smoke, or crack.
Whether for texturizing, drawing, or twisting – our spin finishes will deliver exactly what you need. Their lubricating capability can be tailored to suit your requirements whether super-smooth or moderately smooth. Our products are absolutely thermally stable and non-volatile without leaving residues. The yarns will be as resilient and strong, as voluminous, as elastic, or as fine as the manufacturer wants. This precision is possible because our chemists have in-depth knowledge of the materials, the machines, and the processes. With our competence, we develop perfectly tuned high-performance products for optimal results in any processing environment.
Best in class for high performance
Fiber manufacturers around the world appreciate the reliability of our spin finishes. In terms of emulsifying capability and solubility, our products are at the top of the class. The same goes for wetting properties, film building on the fiber surface, yarn cohesion, and thread adhesion. Easy handling, high storage stability, and good wash-out characteristics are all part of the package with Pulcra Chemicals’ products. Our products will not cause any chemical reaction with the yarn, aggressive effects on metals, paints, or materials. Moreover, our chemical solutions are designed for high occupational safety and minimized environmental burden.
Problem solutions and optimizations for every machine technology
No matter what technology you use and what fiber grades you produce, we know the tasks involved and provide matching solutions that help you to meet the most stringent of consumer demands. Constant research is an important part of Pulcra Chemicals, and we also maintain a permanent dialogue with leading machine manufacturers.
