High Performance Industrial Applications of Synthetic Multifilament Yarns
The most advanced modern industrial textiles used in commercial packaging; marine cordage; and geotextile engineering require specialized synthetic fibers that can withstand extremely high levels of stress (tensile), long periods of continuous friction (abrasion), and harsh environmental conditions. Natural fibers and non-reinforced synthetic yarns often fail when subjected to excessive dynamic load, degrade rapidly due to ultraviolet radiation exposure, and absorb too much water which results in rotting and bacterial growth. Technical textile manufacturers overcome these problems by using continuous filament polyolefin strands designed specifically for use in high-stress applications. The addition of high tenacity PP multifilament yarn to specialized weaving, braiding and sewing processes creates a lightweight but very durable material that can be utilized in many different types of industrial applications. Buying continuous filament products from a reputable PP multifilament yarn manufacturer ensures consistent denier; high tensile strength; and multi-season outdoor durability across all global industrial markets.
Molecular Structure & Advanced Extrusion Processing
Polypropylene Multifilament Strands (PMS) offer both a high degree of physical performance, as well as an extreme level of processing control; this is because PMS utilize a specialized molecular alignment and extrusion process. To create PMS, a very pure polypropylene resin granule is first melted and then homogenized prior to being fed into a precise thermal control system. After melting and homogenization, the liquid polypropylene is then forced through a series of multiple small-diameter hole spinnerets, producing several dozen continuous micro-filaments. Immediately after leaving the spinnerets, each individual micro-filament is cooled down and bundled together with others. Control of the drawing process used to produce PMS allows the linear molecular structure of the polymer chains within each micro filament to be aligned. As a result, PMS have a significantly increased tenacity. Depending on how much flexibility and/or surface adhesion is required for a particular application, the bundled filaments can either be processed as flat yarns, intermingled yarns, or twisted yarns. The precise molecular alignment achieved during the production of PMS provides the resulting yarn with characteristics such as a very high strength-to-weight ratio, very little elongation, and excellent resistance to mechanical wear.
High Tensile Tenacity and Lightweight Physical Dynamics
Polypropylene multifilament yarns have several unique technical benefits over other synthetic fibers such as polyester and nylon, and also over natural fibers like cotton. One of these benefits is that polypropylene multifilament yarns are very light weight, having a extremely low specific gravity, yet they possess an extraordinary amount of breaking strength. Since polypropylene multifilament yarns weigh much less than standard synthetic fibers polyester, nylon, etc, and also less than standard natural fibers cotton, etc, it is considered one of the lightest commercial synthetic polymers on the market today. This allows manufacturers to create products that will float on top of water, but do not absorb any moisture. Although polypropylene multifilament yarns are lightweight, some of the high-tenacity versions can provide outstanding amounts of tensile resistance. Therefore, polypropylene multifilament yarns are ideal for use in heavy duty load bearing applications. Because of this dual property of having high break strength and being lightweight, industrial manufacturers are able to develop lightweight cargo nets, stronger lifting slings, and larger capacity bulk packaging products. All of these products can be manufactured with less dead weight which will help reduce shipping costs associated with transportation logistics.
Moisture resistance, chemical inactivity, environmental protection
Industrial textiles are used in many different types of environments that present various challenges such as continuous moisture, exposure to chemicals, acid based soil conditions and direct sunlight. Since polypropylene has a natural hydrophobic molecular make up it absorbs almost no water. This means that products made with these yarns will have the same weight, tensile strength and structural integrity after being placed in both fresh and saltwater they also dry very quickly and do not develop mildew, rot or fungus. In addition, the polymer is chemical inert, so it will resist degradation by many of the most commonly encountered acids, alkalines, organic solvents and other industrial chemicals. Finally, when specialized UV stabilizer masterbatches are added to the polypropylene during melt extrusion, the yarn will maintain its physical characteristics for many years while exposed to direct sunlight.
Applications in Ropes, Cordage, and Marine Networks
Polypropylene multifilament yarns are widely used by the marine, fishing and commercial shipping industries in the manufacturing of high performance ropes, braided cords and heavy duty nets. These multifilament yarns float naturally and resist being waterlogged. Therefore, when marine mooring lines and commercial fishing nets are made with these filaments, they remain light weight and easy for crew members to work with even when it is raining hard or the sea is rough. Multifilament bundles have a smooth, non-abrasive surface that minimizes internal friction between each strand as the rope is flexed repeatedly. This helps prevent internal fiber fatigue caused by dynamic wave action. In addition, the ability to add vibrant color masterbatches to the polymer melt provides a means for permanently color coding safety lines, climbing gear and commercial tie downs.
Technical textiles, geotextiles and industrial sewing thread
In addition to being used to make cordage and netting, multi filament polypropylene fibers are critical structural elements in today’s advanced technology based technical textiles, geotextile fabrics and strong industrial sewing threads. Multi filament polypropylene fibers that have a high tenacity are woven together to create woven geotextile fabrics which are placed under roadbeds, railway beds, and soil embankments to provide filter function for a long period of time; separate functions and structural support for the ground. High strength multi filament polypropylene fibers are utilized only to sew FIBC jumbo bags, large cement sacks and woven polypropylene containers. Since the multi filament polypropylene fibers have a smooth filament surface, they can pass easily through high-speed industrial sewing machines without breaking, fraying or melting the needle due to heat.
Economic Value, Processing Efficiency, and Recyclability
To evaluate material selections for large-scale industrial manufacturing, there must be a balance between the initial procurement costs of materials with their production output and the environmental impacts associated with using them. Compared to other engineering polymers such as nylon, polypropylene resins require significantly less heat during the extrusion process; this results in less energy being consumed and ultimately, a less expensive manufacturing process. Additionally, the smooth bonding of multiple strands of filament whether they are twisted together or intermingled, results in fewer interruptions in production when used in high speed weaving, knitting and braiding applications. Environmentally speaking, polypropylene is a 100% recyclable thermoplastic polymer. It is possible to convert production off cuts, scrap yarn and retired textile products back into raw materials by melting and pelletizing these items into secondary plastics, which supports circular economy models and decreases the amount of waste sent to landfills.
