High Tenacity Semi Dull Nylon 66 Filament Yarn is a high-performance polyamide fully drawn filament (FDY). Titanium dioxide matting agent is added during the spinning stage, combined with high stretch technology, while achieving three core characteristics: ultra-high breaking strength, soft matte appearance, and excellent wear and heat resistance. It is a core raw material for industrial textiles, outdoor equipment, automotive textiles, high-end woven belts, and sewing threads. Compared with ordinary bright nylon 66 and nylon 6 filament, it balances mechanical properties and low-key texture, solving the pain points of bright light filament glare and rough appearance of ordinary industrial filament. It is widely purchased by weaving factories, ribbon factories, and composite material manufacturers worldwide.
1、 High strength mechanical properties, capable of bearing heavy loads without easily breaking
High strength semi matte PA66 filament can achieve a fracture strength of 7.5-9.2g/d through directional molecular stretching, which is much higher than conventional civilian nylon filament.
1. High breaking strength : resistant to sustained tensile and impact loads, suitable for scenarios requiring sustained load-bearing capacity;
2. Excellent elastic recovery : It can quickly rebound after being stretched under force, and is not easily permanently deformed after repeated deformation. It has outstanding fatigue resistance and is not easily brittle under long-term dynamic loads;
3. Impact resistance: Good toughness under instantaneous impact and collision conditions, and less prone to brittle tearing;
4. Lightweight and high-strength: Under the same strength, the yarn is finer and the fabric is lighter, reducing the weight of the finished product.
This feature is very suitable for products such as safety webbing, lifting ropes, airbag base fabrics, industrial sewing threads, etc. that have rigid indicators for tensile strength.
2、 Semi matte texture, visually advanced non reflective
The semi extinction effect comes from uniformly adding titanium dioxide (TiO ₂) extinction particles to the spinning melt, scattering light, distinguishing the reflection of bright silk piercing glasses from the dull and dull like full extinction.
1. The fabric presents a soft and delicate matte finish, with no strong light reflection. Outdoor equipment, tactical fabrics, and car interiors will not produce glare;
2. The extinction particles inside the fibers are evenly dispersed, the fabric surface is dry and uniform, and there are few fabric defects;
3. Good dyeing stability, uniform coloring, excellent color fastness, can be dyed with the original solution or acid dyes in the later stage, the finished product has a warm and moist color, and will not have the common "mirror high gloss" problem of glossy silk;
4. Smooth touch, no glaring plastic luster, balancing industrial performance and appearance quality.
3、 Excellent wear resistance and friction durability, extending the service life of products
Nylon itself is a category with excellent wear resistance in synthetic fibers, and high-strength PA66 semi dull filament is further improved on this basis:
Resistant to repeated friction and scratching, the fabric has slow fuzzing and low wear and tear under continuous friction conditions;
The friction coefficient is stable, and it is not easily damaged when used for conveyor belt base fabric, rubber hose reinforcement layer, tent fabric, and luggage fabric for long-term use;
Suitable for frequent friction scenarios, such as outdoor backpack straps, protective fabrics, and conveyor belt reinforced fabrics.
Comparison: Although nylon 6 is cheaper, its heat resistance, creep resistance, and long-term wear resistance are weaker than PA66 high-strength fibers.
4、 Strong thermal stability, high temperature resistance, and creep resistance
Nylon 66 has a melting point of about 260 ℃, higher than nylon 6, and better dimensional stability in high-temperature environments
1. Controllable thermal shrinkage rate, stable size after shaping, small deformation under high-temperature processing and continuous heating conditions, and resistance to creep;
2. Short term tolerance to high working temperatures, suitable for scenarios such as automotive parts, rubber hose skeleton layers, and transmission belts that require contact with heat sources;
3. Good thermal aging performance, not easily prone to rapid yellowing and strength degradation in long-term warm environments.
5、 Chemical and Environmental Tolerance
1. Oil resistant, resistant to most organic solvents, suitable for industrial oily environments;
2. Moderate resistance to weak acids and bases; Maintain stable performance in regular outdoor rainy and humid environments;
3. Disadvantages: Strong acidic environment can corrode fibers; Long term strong UV environments require additional UV resistant additives for modification.
6、 Stable weaving processing performance
1. The long filament is evenly dried, with less breakage of single filaments, and low breakage rate during warping, weaving, and knitting processes, improving production efficiency and reducing downtime losses;
2. Suitable for flat knitting, warp knitting, weft knitting, ribbon weaving machines, and high-speed sewing equipment;
3. It can be blended and interwoven with other fibers such as polyester and aramid to achieve composite functions;
4. Rich specifications, common specifications: 150D, 210D, 280D, 420D, 630D, can be customized according to customer's denier and single filament count.
7、 Mainstream application areas
1. Automotive textile: airbag base fabric, seat belt webbing, automotive interior fabric, rubber hose reinforcement layer;
2. Outdoor and functional textiles: high-end tent fabrics, climbing ropes, backpack straps, tactical equipment fabrics;
3. Industrial textiles: high-strength industrial sewing thread, conveyor belt base fabric, protective fabric, fishing net, lifting webbing;
4. Luggage and high-end equipment: heavy-duty luggage fabrics, protective covers, and composite reinforced substrates.
