Shanghai Petrochemical: How Crude Oil Turns Into Colorful Acrylic Textiles

Have you ever wondered how a single drop of crude oil is transformed into bright, colorful chemical fiber products?

After extraction, crude oil is transported to refineries and distilled via atmospheric and vacuum distillation units to extract naphtha and other hydrocarbon components.

Naphtha is delivered to ethylene plants, and cracked into propylene inside cracking furnaces under high temperatures ranging from 700℃ to 900℃.

Under the catalysis of special catalysts, propylene undergoes ammoxidation reaction with ammonia and oxygen to generate acrylonitrile, the core raw material for acrylic fiber.

After polymerization and devolatilization treatment, acrylonitrile is mixed and dissolved with solvents to prepare spinning dope. Color pastes of diverse hues are blended evenly into the spinning dope at this stage. The pigmented dope is then fed into spinning machines.

The nascent fibers extruded from spinnerets go through drafting, drying, heat setting and other procedures, and are finally made into finished acrylic fibers.

According to customized market demands, one single spinning production line can manufacture multiple acrylic products, including regular fibers, colored fibers and anti-pilling fibers.

Processed by downstream textile manufacturers, acrylic fibers are made into daily necessities we use all year round, such as sun umbrellas, camping tents and garments.

Historical Throwback: The Birth of China’s Acrylic Industry

Back in the early 1970s, to solve the nationwide clothing shortage crisis, the chemical fiber facility of Shanghai Petrochemical was officially approved — reviewed by Chairman Mao and instructed by Premier Zhou Enlai. Acrylic fiber stood out as the blockbuster star product at that time🌟.

In recent years, to meet upgraded market demands for clothing texture, color richness and wearing comfort, Shanghai Petrochemical has kept optimizing and iterating acrylic fiber products, the vital raw material for fashionable textiles.

Commonly known as synthetic wool, acrylic fiber is an indispensable synthetic chemical fiber. Different customized grades boast exclusive functional strengths. Let’s explore our five premium treasure-grade acrylic products:

1. Dope-Dyed Acrylic Fiber

Product Features

Pigments are blended into spinning dope at the initial fiber forming stage, fundamentally eliminating common textile defects such as uneven dyeing and surface blemishes caused by post-dyeing. It cuts down pollutant emissions from traditional textile dyeing procedures, achieving eco-friendly production.

The finished fabric presents uniform, saturated color with outstanding color fastness, resisting discoloration under long-term sunlight exposure.

Application Scenarios

Outdoor sun-shading supplies including beach umbrellas, camping tents, outdoor banners and yacht tarpaulins; knitted fabrics, apparel textiles, plush products; outdoor furniture fabrics and performance outdoor garments.

2. Anti-Pilling Acrylic Fiber

Product Features

Featuring fluffy bulkiness and silky skin-friendly touch, its core advantage lies in excellent anti-pilling performance. The fabric can maintain neat and brand-new appearance after long-term wearing and usage, which is versatile and durable for daily outfits.

Application Scenarios

All kinds of knitted garments, fashion fabrics and plush textiles.

3. Superfine Denier Acrylic Fiber

Product Features

Produced via micro-pore spinneret technology, the fiber is ultra-fine, lightweight and extraordinarily soft, delivering mild and elegant fabric luster.

Balancing sturdiness and durability, it outperforms ordinary acrylic fibers greatly in moisture absorption and air permeability. The textile fits skin perfectly with excellent drapability, bringing unrestrained and comfortable wearing experience.

Application Scenarios

High-end apparel fabrics, lightweight knitted sweaters and electrostatic flocking products.

4. Anti-Static & Solar Heat-Absorbing Acrylic Fiber

Product Features

It delivers inherent thermal retention performance while eliminating static electricity interference, realizing highly practical textile functions.

Adopting pre-spinning dope addition technology, its functional effects are wash-resistant and not easy to fail. With remarkable solar heat-absorbing capacity, it can efficiently lock body heat to keep wearers warm.

Application Scenarios

High-end garments and ultra-thin knitted apparel.

5. Antibacterial Acrylic Fiber

Product Features

Fabricated via physical modification technology, antibacterial agents are firmly solidified inside fiber structures and released slowly to form a lasting protective barrier. It delivers stable bacteriostasis and deodorization effects.

The fiber can effectively inhibit harmful bacterial reproduction and remove peculiar smells. It maintains soft handfeel and great weaving performance, with biocompatible and eco-friendly properties harmless to human bodies and the natural environment.

Application Scenarios

Knitted apparel, home textiles, bedding products and handmade woven crafts.

Epilogue: Oil Woven Into Daily Comfort

From summer outdoor sun-shading gear to intimate daily wear and household supplies, diversified Shanghai Petrochemical acrylic fiber products have penetrated every corner of modern life. Supported by reliable quality and versatile customized functions, they safeguard comfortable and cozy daily life for the public.

Next time when you use sun umbrellas or camping tents outdoors, take a quick look at the fabric. Chances are, you are wearing and using our high-performance treasure-grade acrylic fiber!
