As a key component of textile and industrial materials, the specifications of monofilament yarn are not just simple parameter indicators, but a comprehensive reflection of production processes, material properties, quality control and downstream applications.

Basic description of specifications

Data description: Basic parameters of monofilament yarn

Diameter and fineness

• The diameter of monofilament yarn usually ranges from 5 microns to 50 microns.
• Data description: The diameter of high-end clothing yarn is mostly 8~15 microns, while industrial filter materials may use yarns above 20 microns.

Gram weight and density

• Use "g/m2" or "tex" (weight per kilometer, in grams) to describe.
• Data description: The tex value of industrial yarn is generally between 1.2~3.0, while high-end fabrics require lower tex values ​​to ensure fine fibers.

Tensile strength and elongation

• The tensile strength is usually between 2.0~6.0 g/denier, and the elongation is generally between 15%~30%.
• Data description: Different raw materials and process parameters determine specific values ​​to ensure that the yarn has sufficient wear resistance in mechanical processing and terminal applications.

Heat resistance and chemical resistance

• Data description: Some engineering applications require yarn to work stably at 80°C or even higher temperatures, while also having chemical corrosion resistance.

Production process and process impact

Process impact: Regulation of specifications by production technology

Stretching and heat setting process

• Process impact: The stretching ratio is controlled between 3:1 and 6:1 to make the fiber molecular chains more closely arranged, thereby improving the mechanical strength of the yarn.
• The heat setting temperature is generally set between 200°C and 250°C to stabilize the fiber structure and reduce rebound, ensuring the consistency of the product in subsequent processing.

Material selection and modification technology

• Process impact: Different raw materials (such as polyester, nylon) and their molecular weight (usually between 20,000 and 40,000) directly affect the wear resistance and chemical stability of the yarn.
• Adding modifiers (concentration controlled at 0.5% to 3%) can achieve anti-ultraviolet, antistatic or flame retardant functions, expanding the application field of yarn.

Surface treatment and post-processing

• Process impact: Through surface coating or smoothing treatment, the surface roughness (Ra value) of monofilament yarn is reduced to below 0.1 micron, improving dyeing effect and antistatic performance.

Data reference and technical impact

Data reference: Specific technical indicators

Diameter and gram weight

• Diameter: 8~15 microns are suitable for light fabrics, and 20 microns or more are suitable for industrial filtration.
• Gram weight: tex value 1.2~3.0 is suitable for industrial products, while high-end products require lower values.

Tensile strength and elongation

• Tensile strength: 2.0~6.0 g/denier, the specific values ​​of different raw materials vary.
• Elongation: Keep between 15%~30% to ensure yarn flexibility and stability.

Technological impact: Improvement of production and testing technology

Intelligent testing system

• Technological impact: In the future, automated testing and big data monitoring will more accurately control each indicator of the yarn to ensure high consistency and stability of the product.
  

Application of environmental protection technology

• Technological impact: Low-energy consumption and low-pollution production processes not only meet international environmental standards, but also promote the upgrading of yarn specifications to a more environmentally friendly and healthier direction.

Data application and practical significance

Data application: Application of key indicators in various fields

Textile and clothing industry

• Data application: Monofilament yarns (diameter 8~15 microns) for light fabrics ensure soft and breathable fabrics; while yarns with high tensile strength (over 5.0 g/denier) are suitable for sportswear to ensure wear resistance and tear resistance.
  

Industrial and engineering materials

• Data application: Yarns with larger diameters (over 20 microns) provide high porosity and chemical corrosion resistance in filter cloths; in building protection, products with a tensile strength of over 4.0 g/denier improve the safety of reinforcement materials.
  

Special application areas

• Data application: Nonwoven fabrics for medical protection require yarns to meet high cleanliness standards and comply with ISO or FDA certification; yarns for electronic products require special coatings to ensure insulation and stability.

Practical significance: The far-reaching impact of specification parameters on downstream products

Quality assurance of clothing fabrics

• Practical significance: Accurate diameter and weight control not only improves the appearance and feel of the fabric, but also directly affects the comfort and durability of clothing.
  

Safety and stability of industrial products

• Practical significance: High tensile strength and chemical resistance ensure that the product remains stable in harsh environments, prolongs its service life and reduces maintenance costs.
  

Multifunctional expansion and market competitiveness

• Practical significance: The research and development of functional yarns such as flame retardant and antibacterial, through modification and intelligent detection technology, not only meets the personalized needs of the market, but also promotes technological innovation and competitiveness of the entire industry.
