Polyester fiber has strong plasticity and processability in textile materials due to its designable molecular structure, adjustable spinning process, and wide adaptability to post-processing. It can be precisely customized according to different application scenarios, functional requirements, and appearance styles, making it the most adaptable and widely used fiber material in modern textile industry. In fact, plasticity is mainly reflected in the following aspects:
1、 Shape and structure plasticity: customizable thread shape and cross-section
We can produce various forms such as long filament, low elasticity filament, high elasticity filament, irregular filament, hollow filament, ultra-fine yarn, composite filament, short fiber, etc. according to their applications, to meet the full range of needs from clothing, home textiles to industrial textiles.
The cross-section can be designed in circular, trilobal, cross shaped, flat, hollow, polygonal and other structures to achieve different gloss, feel, fluffiness, breathability and warmth.
The range of fineness is extremely wide, and it can produce ultra-fine and lightweight fabrics, as well as coarse and high-strength industrial silk, with stable molding and high uniformity.
The hand feel and elasticity can be adjusted through curling and fluffiness techniques, achieving various natural fiber effects such as imitation cotton, imitation wool, imitation silk, imitation linen, etc.
2、 Physical and mechanical properties plasticity: both soft and hard elasticity can be controlled
Key indicators such as strength, modulus, elongation, elastic recovery, and shrinkage can be precisely controlled through processes such as spinning, stretching, and heat setting, achieving diversified performance from softness to high strength and from high elasticity to low shrinkage.
Having excellent heat setting properties, the material after molding is firm, not easily wrinkled, not easily deformed, and has stable dimensions.
The elasticity and fluffiness can be adjusted, and it can be used for insulation filling, rebound cotton, sofa cushions, mattresses, embroidered fabrics, etc. It will not collapse or deform after long-term use.
It can achieve characteristics such as high strength and low elongation, low strength and high elongation, high wear resistance, and fatigue resistance, meeting the requirements of high strength and high reliability in the industrial field.
3、 Functional modification and plasticity: capable of endowing various high-performance properties
By copolymerization, blending, adding functional masterbatch, and post finishing, fibers can be endowed with various functional properties:
Moisture wicking, antibacterial, flame retardant, anti-static, anti pilling, UV resistant, hydrophilic, hydrophobic, anti fouling, cool, warm, negative ion, etc.
It can achieve original liquid coloring, high color fastness, environmental protection and energy saving, and uniform color.
High value-added functional products such as antibacterial fibers, flame-retardant fibers, conductive fibers, heating fibers, and UV resistant fibers can be prepared.
Durable and stable, it can meet the stringent requirements of clothing, home textiles, medical, automotive interiors, outdoor products, and more.
4、 Process plasticity: Suitable for the entire textile processing process
It can be blended, interwoven, wrapped, and compounded with fibers such as cotton, linen, silk, wool, viscose, modal, and Tencel, complementing each other's advantages and enhancing the overall performance of the fabric.
Suitable for various processing methods such as machine weaving, knitting, warp knitting, weft knitting, non-woven fabric, hydrojet, meltblown, spunbond, needle punching, embroidery, etc., with stable molding and high production efficiency.
During the processing, it is not prone to wire breakage, pilling, and has stable dimensions. It is suitable for high-speed automated production lines and has a high yield rate.
Multiple processes such as adding elasticity, networking, splicing, double twisting, sizing, and shaping can be carried out to meet different weaving requirements.
5、 Plastic appearance style: versatile styles and rich textures
It can produce various appearance effects such as semi gloss, high gloss, matte, silk like luster, wool like texture, hemp like texture, etc.
Excellent dyeing performance, complete chromatography, good uniformity, and high color fastness, can meet diverse design needs such as fashion, home textiles, and decoration.
Rich visual and tactile effects can be achieved through processes such as sanding, pulling, wrinkling, embossing, hot stamping, printing, and lamination.
The style covers a full range of categories including simplicity, light luxury, sports, leisure, business, outdoor, home, etc., adapting to various design concepts.
6、 Post organization plasticity: there is a large space for expanding performance and added value
Suitable for almost all textile finishing processes such as dyeing, shaping, waterproofing, oil resistance, stain resistance, wrinkle resistance, softness, stiffness, coating, laminating, and composite.
Flexible adjustment of hand feel from soft to hard, gloss from bright to dull, and functionality from basic to good can be achieved through organization.
Strong processing compatibility, less likely to damage fiber structure, can significantly enhance product added value and market competitiveness.
