The special process that distinguishes split film industrial filament from ordinary flat filament. The stretched film splits into reticular fiber bundles through mechanical or air flow action, forming a unique "split film" texture. This process determines the width of the fibers (typically 1-5mm) and their surface morphology, directly influencing the softness and nodular performance of the final product. The fibers after membrane splitting feel soft to the touch but are tough in texture, which is significantly different from the uniform and smooth surface of ordinary filaments.
Winding molding is the final process, where the split film fibers are wound onto a tube to form a spindle. The winding tension needs to be precisely controlled. If it is too large, it will cause excessive stretching of the fibers; if it is too small, it will result in loose winding. The standard paper tube size is usually an inner diameter of 40mm, an outer diameter of 48mm, and a height of 290mm, with a net weight of approximately 4KG per roll.
Application fields and product advantages
Split-film industrial filaments have been widely used in multiple industrial fields due to their unique performance combination, especially in fishery-related applications.
Fishery applications are the most traditional field of split-film industrial filaments. The fishing nets woven from it have the advantages of light weight, resistance to seawater corrosion and anti-biological adhesion, and are widely used in scenarios such as trawl nets, encircling nets and aquaculture cages. Compared with traditional nylon fishing nets, splined film industrial wire fishing nets are lighter (with a weight reduction of about 30%), easier to operate, and do not require anti-corrosion treatment, significantly reducing the usage cost. It is worth noting that the flat structure of the schizomembrane filaments makes them have excellent nodule performance and the net knots are not easy to slip off, which is an important reason why they are particularly suitable for fishing net applications.
The application in the agricultural field is becoming increasingly widespread. The sunshade nets, insect-proof nets and other products made of split-film industrial filaments have the advantages of good weather resistance, anti-aging and low cost. In modern agriculture, these products are widely used for crop protection and effectively reduce the use of pesticides. Tests show that high-quality split-film industrial filaments can still maintain over 70% of their original strength after being used outdoors for 3 to 5 years.
The industrial uses are showing a diversified trend. Rubber tire gaskets woven from split film industrial filaments have the advantages of light weight, low moisture absorption rate and small static electricity effect, and have become important auxiliary materials in the tire manufacturing industry. In addition, the filter cloth woven from split membrane industrial silk is widely used in environmental protection, mineral processing, chemical engineering, metallurgy and other industries. Its smooth surface and good wear resistance are particularly suitable for solid-liquid separation operations. In the packaging field, split film filaments can be used to produce high-strength bulk bags and ton bags, meeting the transportation demands of heavy goods.
Environmental protection engineering is an emerging application field. Geotextiles made from split film industrial filaments are used in landfill isolation layers, sand prevention and soil stabilization nets and other projects, taking advantage of their good chemical stability and strong resistance to ultraviolet rays. With the increasing environmental protection requirements, the research and development of degradable spliced film industrial filaments has also made progress. Spliced film filaments produced from bio-based materials such as PLA/PHBV have begun to be applied in occasions with higher environmental protection requirements.
