Spinnerette Packs TRIZ Cases
- Melt Spun Polymer Filament Bundles with Dynamic Spin Pump Control
Varying spin pump outputs over time generates consistent color variation in melt spun polymer filaments while maintaining constant total volume.
- Latent Helical Artificial Turf Filaments via Thermal Activation
Thermal activation transforms straight filaments into helices post-installation, resolving the trade-off between aesthetic shape and installation time.
- Capillary Multi-Jet Nozzle for High-Throughput Nanofiber Fabrication
A capillary multi-jet nozzle uses a screw groove system and customizable pores to produce multiple non-interfering jets.
- Aromatic Polyamide Filament Manufacturing via Alternating Feed Paths
Alternating inner and outer feed paths create a vortex for uniform polymerization of aromatic polyamide filaments.
- Polyethylene Fiber Spinneret Orifice Segmentation for Shear Stress
Segmented spinneret orifices resolve the contradiction between high fiber strength and spinning efficiency by optimizing shear stress generation.
- Bilobal Spinneret Orifice Orientation for Filament Cooling
Asymmetric orifice orientation improves uniform cooling and attenuation of bilobal filaments, resolving non-uniform heat distribution issues.
- Spinning System Cooling Unit Temperature Control
A spinning system cooling unit suppresses temperature drops at the spinneret using a dedicated blower.
- Acrylic Fiber Spinning Solution Preparation via Low-Temperature DMSO Mixing
Spraying cold DMSO onto polymer powder prevents gel formation and filter clogging, enabling continuous acrylic fiber manufacturing.
- High-Density Spinning Nozzle for Uniform Nanofiber Production
Segmented spinning nozzles with 600-1200 holes per square millimeter prevent fiber adhesion and maintain hole density during wet spinning.
- Electrospinning Nozzle Head with Segmented Ring Gap for Uniform Deposition
Segmented ring gap nozzle head stabilizes Taylor cone formation, resolving uneven liquid spreading and boosting nanofiber production yield.
- Electrospinning Nozzle with Movable Needle for Dual-Mode Operation
A detachable air jacket nozzle adjusts needle protrusion length to switch between pure and air electrospinning modes.
- Elliptical Spinneret for Porous Ultra-Soft Polyester Fiber
Porous ultra-soft polyester fiber uses an elliptical spinneret arrangement to enhance cooling efficiency and dyeing uniformity.
- Spunbond Diffuser Secondary Air Angles for Homogeneous Filament Deposition
Angled secondary air entry gaps in a spunbond diffuser create uniform airflow that maintains filament deposit homogeneity at high production speeds.
- Spunbond Filament Plant Porous Filter Droplet Control
Sintered porous filter in spunbond plant minimizes polymer waste by controlling droplet formation at the spinneret.
- Extrusion Nozzle Columns Integrated with Base Plate
Integrates extrusion columns into the base plate, eliminating separate support plates to reduce pressure loss and increase throughput.
- Extrusion Head Laminar Chamber Vibration for PAN Filament Orientation
Vibrating elements in a laminar chamber extrusion head align polymer molecules, resolving facility space constraints while improving mechanical properties.
- Melt Blowing Louvers Control Air Velocity
Louvers prevent ambient air entrainment and reduce compressed air costs by maintaining high velocities in the melt blowing process.
