300D Polyester Filament Yarn

The 300D polyester filament yarn is a continuous filament yarn made of 100% polyester (polyester). The specification "300D" indicates its linear density (denier), and it falls within the medium-thick and highly durable standard of industrial-grade yarns. It is formed by bundling multiple single threads (such as 48F, 72F, 96F, etc.), and possesses the unique physical properties of high strength, smoothness, uniformity and low elongation of filament yarns. This product is the core raw material for luggage, webbing, outdoor products, industrial fabrics and sewing threads, etc. It is renowned for its excellent durability, stable performance and good processing adaptability.

High strength and durability
It has excellent tensile strength and impact resistance, is wear-resistant and tear-resistant, ensuring that the final product is durable.
Low elongation provides good dimensional stability and is less likely to deform under repeated loads.
Excellent processability and quality
The yarn has a high degree of evenness in fiber dryness, a smooth surface, and very few fuzzes, which is conducive to high-speed weaving and reduces the breakage rate.
It has good dyeing performance, high color fastness, bright and uniform colors.
Good resistance to ultraviolet rays, chemical corrosion and mold, suitable for various harsh environments.
Functional and environmental options
Customized functional models such as dyeing directly from the raw material (dyed yarn), high strength, flame retardant, UV resistance, etc. can be provided according to requirements.
Reclaimed polyester (rPET) filament yarns that meet environmental standards can be provided, made from recycled PET bottle chips and obtaining international certifications such as GRS.
Economical and efficient
As a standardized industrial raw material, it has high cost-effectiveness, stable supply, and helps control production costs.

Polyester low-tensile filament is made from polyester chips as raw material. Through high-speed textile process, it is the ideal raw material for warp knitting, weft knitting and machine weaving. It features high breaking strength, high elastic modulus, excellent heat stability, good rebound performance, strong heat resistance, light resistance and corrosion resistance.

Luggage and outdoor equipment
Travelling suitcases, backpacks, handbags, fabric for tents, sleeping bags, outdoor sunshades, car and boat covers, etc.
Industrial textiles and straps
Safety nets, safety belts, lifting straps, industrial conveyor belt frames, awning fabrics, advertising light box fabrics, various industrial and civilian woven fabrics.
Home and decoration
Sofa fabrics, table and chair covering materials, curtains, carpet backing, decorative binding ropes, etc.
Sewing threads and special purposes
High-strength industrial sewing threads, shoe uppers and shoe materials, special industrial filter fabrics, etc.
