New development of foreign chemical fiber test equipment - melt spinning test line

The research and development activities of polymers and fiber materials are inevitably accompanied by the construction, renewal and development of research and test equipment, such as the attempt to develop functional multi-component fibers exhibited by the melting test equipment platform. The technological revolution of chemical fiber test equipment reflects the path of polymer fiber technology innovation in the world from one aspect, and brings inspiration and inspiration to related companies.

The polymer and chemical fiber testing equipment provided by British Fiber Extrusion Technology Co., Ltd. (FET) is characterized by high energy efficiency and low cost. The equipment design is designed for both R&D and commercial production, covering polymer and additive testing and small batches. Commercial production and functions such as new fiber materials and biopolymer testing. The good process flexibility of melt-spinning research equipment is widely favored by researchers. The company's melt-spinning research equipment series consists of a FET-100 extrusion unit, a FET-101 multifilament unit, an FET-102 spun-melt nonwoven unit, and an FET-103 monofilament forming unit.

Polymer melt spinning research equipment line configuration

FET's melt spinning research equipment can be configured with various combinations of extrusion and spin forming devices according to user requirements. The extrusion unit can process a variety of polymer materials, and the forming unit can perform monofilament, multifilament, and spunbond and meltblown nonwoven experiments, including two-component and three-component composite fiber tests.

The melt spinning device and melt-blown nonwoven test platform provided by FET have been used for the processing of bioabsorbable polymer fibers. The main biopolymer materials used include polyglycolide (PGA) and poly-L-lactic acid (PLLA). , poly-p-dioxanone (PDO) and polycaprolactone (PCL). Biomedical fiber products relate to multifilament, monofilament, spunbond nonwoven products, bicomponent monofilament and multifilament, and hollow core filament products.

In the same type of test equipment, the melting test equipment of Hills Company of the United States can undertake research and test of multi-component fibers. At present, the test equipment has been applied in many fields and accumulated rich experience, including: PP /PE sheath-core spunbonded nonwoven fabric or low-melting carded nonwoven fabric and meltblown fiber web composite product, used for surgical fiber products; split-type micro-denier fiber, used as advanced wipes; And a variety of polymer fiber products, used as carpet base fabric; sheath core type copolyester/polyester fiber products for roofing protective coils; sheath core type meltblown nonwoven fabrics for gas permeable membrane materials; Antistatic fiber of core or conductive sheet structure; novel carbon fiber precursor; multi-island or composite fiber of two or more polymer components, used for functional fibers (recognition function);

Conductive fibers, polymer optical fibers (POF) need to have good flexibility, durability and touch, and can be used in wearable textiles. Researchers at the EMPA laboratory in Switzerland used a low-pressure plasma spray method to form a conductive coating of 100-200 nm on the surface of monofilaments and multifilaments; and developed a "overjacketing crosshear" process, which is about to melt. The polymer enters the extrusion head in a vertical direction to form a skin layer on the surface of the monofilament. Tests show that the polymer coating is uniform, the thickness can be adjusted, suitable for processing a variety of polymer materials, is a practical technology for the development of high-performance flexible fiber products, products can be used for sensors and optical radiation fiber products.
