IC vertical strip liquid ammonia air layer mercerized fabric: full analysis of technology, performance and application trends

IC vertical strip liquid ammonia air layer mercerized fabric is a high-end pure cotton fabric that combines the four core technologies of IC vertical strip texture design, liquid ammonia finishing, air layer structure, and mercerization technology. It combines the beauty of three-dimensional vertical strips, the smooth texture of liquid ammonia mercerization and the warm and breathable characteristics of air layer. It is the preferred fabric for high-end business wear, casual wear, and light luxury home wear.

1. Principles: core logic of performance for multi-process collaboration

1. The IC vertical strip texture forming principle relies on differentiated coil knitting technology. During weaving, the yarn feeding amount and looping trajectory of some knitting needles are adjusted through a computer-controlled knitting machine, so that regular vertical concave and convex stripes are formed on the surface of the fabric, with even stripe spacing and a strong three-dimensional effect. This structure not only improves the visual layering of the fabric, but also enhances the breathability and wrinkle resistance of the fabric, avoiding the monotony of flat fabrics.

2. The double smoothing principle of liquid ammonia mercerization. Liquid ammonia finishing immerses the fabric in liquid ammonia to swell the cotton fibers, eliminate internal stress, improve the strength and elasticity of the fibers, make the fabric feel soft and smooth, and greatly improve the wrinkle resistance. The mercerization process uses concentrated caustic soda treatment to make the cotton fiber cross-section circular, reflect light more uniformly, and give the fabric a silky gloss. The combination of the two achieves the triple effect of "softness + gloss + anti-wrinkle".

3. The air layer warm and breathable principle fabric adopts a three-layer three-dimensional structure. The surface and inner layers are dense IC vertical strip texture, and the middle is supported by connecting yarns to form a closed air cavity. Still air is an excellent thermal insulator, which can reduce body heat loss; at the same time, the groove structure of the vertical stripe texture accelerates air circulation, solving the pain point of stuffy heat in traditional air layer fabrics, and achieving a balance of "warmth without stuffiness and sweating".

2. Craftsmanship: the fine process from raw materials to finished products

1. The raw materials are screened to select high-count combed cotton yarn (common 40S and 60S specifications) to remove short lint and impurities to ensure the uniformity and strength of the yarn and lay the foundation for subsequent processes.

2. IC vertical strip air layer weaving uses a computer-controlled double-sided knitting machine. The vertical strip spacing and air layer thickness parameters are input. The upper and lower needle beds work together to knit the vertical strip texture of the surface and inner layers. The connecting yarns in the middle are precisely supported to form an air cavity with uniform thickness. The yarn tension is strictly controlled during the weaving process to ensure that the vertical stripe texture is symmetrical and the air layer does not collapse.

3. Liquid ammonia + mercerizing double finishing

• Liquid ammonia finishing is performed first: the fabric is immersed in liquid ammonia at low temperature, and then rolled, steamed, and washed to eliminate the internal stress of the cotton fiber and improve the wrinkle resistance and dimensional stability of the fabric;

• Then proceed to the mercerization process: use concentrated caustic soda solution to treat the fabric, and cooperate with tension control to make the cotton fiber puffed and the surface smooth. After neutralization by washing, the fabric will show a uniform luster;

• Finally, the shape is finalized, the vertical stripe texture and air layer structure are fixed, and the shrinkage rate is controlled within 2%.

3. Application Category: High-end scene coverage in multiple fields

IC vertical strip liquid ammonia air layer mercerized fabric has the characteristics of three-dimensional beauty, smoothness and skin-friendly, warm and breathable, and its application scenarios focus on the high-end clothing field:

• High-end business wear field: used to make business shirts, casual suits, and formal trousers. The mercerized luster enhances the texture of the clothing, the vertical stripe texture adds a sense of design, and the wrinkle resistance of the liquid ammonia finish meets the needs of business people without ironing.

• In the field of light luxury casual wear: it can produce high-end sweatshirts, POLO shirts, and casual jackets. The air layer structure is suitable for spring, autumn and winter, and the soft and smooth feel improves daily wearing comfort.

• Homewear field: As the preferred fabric for light luxury homewear and nightgowns, pure cotton is skin-friendly and non-irritating. Its mercerized texture enhances the home experience, and its air layer warmth is suitable for home needs in autumn and winter.

• Children's clothing field: used to make high-end children's dresses and casual wear. The fabric after liquid ammonia mercerization is soft and boneless, which avoids friction on children's delicate skin. The three-dimensional vertical strip design is more popular among children.

4. Maintenance: Maintenance techniques to extend the life of high-end fabrics

1. For washing requirements, it is recommended to hand wash or machine wash in cold water (water temperature ≤ 30°C). When washing in a machine, put it in a laundry bag to avoid mixing with rough clothes to prevent vertical stripe texture wear and mercerized layer scratches. Use neutral detergent, and prohibit alkaline detergents and bleaches to prevent damage to the liquid ammonia mercerized finishing layer, resulting in a decrease in fabric gloss.

2. Drying and ironing: Dry in the shade or dry on the reverse side at low temperature to avoid sunlight exposure to prevent cotton fiber aging, fabric yellowing, and gloss degradation. The ironing temperature should be controlled below 120°C. When ironing, put a layer of damp cloth on it, and iron the reverse side of the fabric first to avoid direct contact with the mercerized layer at high temperatures, causing uneven gloss.

3. When storing, please fold and store it flat to avoid stretching and deformation of the fabric caused by hanging for a long time; keep the storage environment dry and ventilated, and keep away from sharp objects to prevent snags from damaging the air layer structure and vertical texture; insect repellent can be added to prevent pure cotton fabrics from being eaten by insects.

5. Technology: the core breakthrough direction of performance upgrades

1. Functional composite technology gives fabrics antibacterial, anti-mite, UPF50 + sun protection and other functions through antibacterial, deodorizing and anti-UV finishing, and expands applications in high-end outdoor business wear, medical apparel and other subdivisions.

2. Process optimization technology develops low-temperature mercerization process to reduce the caustic soda treatment temperature and reduce cotton fiber damage; the IC vertical strip weaving program is optimized to achieve personalized customization of stripe width and depth to meet the differentiated needs of the brand.

3. The raw material innovation technology uses organic cotton and recycled cotton raw materials, combined with liquid ammonia mercerization process, to create environmentally friendly high-end fabrics; by blending a small amount of modal fiber, the softness and drape of the fabric are further improved.

6. Trend category: new direction of market development

1. The trend of high-end and light luxury With the upgrading of consumption, the market demand for high-end pure cotton fabrics continues to grow.
