AB yarn jacquard double-sided spandex super soft fabric: full analysis of characteristics, technology and applications

AB yarn jacquard double-sided spandex super soft fabric is a high-end knitted fabric that combines AB yarn two-color texture, jacquard three-dimensional pattern, spandex high elasticity and double-sided super soft texture. It has visual layering, elastic fit and skin-friendly comfort. It has significant application advantages in the field of mid-to-high-end clothing and home furnishings, and meets the market's demand for fabrics that are both beautiful and practical.

1. Principles: Fiber synergy and structural mechanism

1. AB yarn blending principle: AB yarn is blended from two fiber yarns of different colors or thicknesses. It forms a two-color or heterogeneous texture effect through juxtaposition and twisting processes. The front side presents a mottled mixed color texture, and the reverse side retains a delicate yarn base, giving the fabric a unique visual recognition. When paired with 5%-8% spandex fiber blending, the high elastic recovery of spandex can achieve 30%-50% of the fabric's transverse elasticity. The stretch rate and rebound rate are ≥90%, which solves the problem of insufficient elasticity of pure AB yarn fabrics.

2. Double-sided jacquard structure principle: It is woven using a double-sided jacquard knitting machine. Through different knitting needle arrangements on the dial and needle cylinder, a preset jacquard pattern is formed on both sides of the fabric at the same time. The pattern texture is clear and three-dimensional, without additional printing or embroidery. The super-soft finishing process uses sanding and softener penetration to make both the front and back of the fabric achieve a soft and skin-friendly touch, achieving a triple performance stack of "appearance + elasticity + comfort".

2. Technology: core processes of weaving and finishing

1. AB yarn jacquard weaving process

• Yarn preparation: Select two fibers with different characteristics (such as polyester and viscose) to make two types of yarns, A and B. They are paralleled and twisted to form AB blended yarn to ensure uniform yarn twist and avoid end breakage during weaving;

• Jacquard weaving: debug the pattern program of the double-sided jacquard machine, accurately control the lifting and lowering of the knitting needles and the amount of yarn feeding, so that the alignment error of the jacquard patterns on the front and back sides is ≤0.5mm; stabilize the yarn tension during the weaving process, prevent defects such as missing stitches and jumpers, and weave gray fabrics with both texture and pattern.

2. Super soft finishing process

• Pre-shrinking and shaping: The gray fabric is pre-shrunk at a low temperature of 120-130°C to eliminate the internal stress of the weaving, stabilize the width and weight, and avoid deformation in subsequent processing;

• Softening treatment: Using formaldehyde-free environmentally friendly softener, the softener is fully adhered to the fiber surface through padding and drying processes, and then lightly sanded to improve the softness and waxiness of the fabric;

• Finished product shaping: Low-temperature hot air shaping is used to strengthen the three-dimensional effect of the jacquard pattern, while retaining the elastic properties of spandex to ensure that the fabric is washable and not easily deformed.

3. Environmentally friendly process standards: Low VOCs additives are used throughout the process, complying with OEKO-TEX® Standard 100 Class I certification, and meeting the safety requirements for infants and intimate apparel.

3. Application Category: Multi-scenario adaptation fields

1. Mid-to-high-end clothing field: suitable for making autumn and winter sweaters, dresses, home clothes, thermal underwear, etc. The mixed color texture and jacquard pattern of AB yarn enhance the fashion sense of clothing. The double-sided super soft touch is suitable for close-fitting wear, and the elastic properties meet the needs of daily activities and sports stretching. It can also be used for children's clothing jackets and crawlers. Its safety and environmental protection characteristics meet the standards of infant and child textiles.

2. In the field of home textiles: it can be used to produce pillowcases, sofa covers, bedding sets and other soft furnishing products. The jacquard pattern adds a light and luxurious texture to the home space. The double-sided super soft touch improves comfort. The elastic fabric is easy to disassemble and clean, and is durable.

3. Accessories field: used to make scarves, hats, bags and other products. The unique texture of AB yarn jacquard enhances the recognition of accessories, and the super-soft elasticity improves the wearing and using experience.

4. Maintenance: washing and maintenance skills

1. Washing specifications: It is recommended to hand wash in cold water below 30℃, or put it in a laundry bag and choose the gentle machine wash mode; use neutral detergent, prohibit the use of bleach and strong alkaline detergents to prevent fabric fading and elasticity attenuation; turn the fabric over when machine washing to reduce friction damage to the jacquard pattern.

2. Drying and storage: After washing, gently squeeze the water, lay it flat to dry in the shade or hang to dry, avoid exposure to the sun to prevent ultraviolet rays from causing the AB yarn to fade and the jacquard pattern to harden; fold it flat when storing, do not put heavy pressure on the jacquard parts, and can be stored separately in a breathable storage bag to prevent moisture and mildew.

3. Precautions for ironing: Try to avoid ironing; if you need to iron, turn the fabric over, set the low temperature mode (temperature ≤ 110°C), steam iron with a pad, and avoid direct contact with the jacquard pattern to prevent pattern deformation.

5. Technology: core performance indicators and innovation directions

1. Core performance indicators

• Elasticity index: transverse stretch rate 30%-50%, rebound rate ≥90%, elastic attenuation ≤5% after 50 times of washing;

• Appearance indicators: jacquard pattern clarity ≥95%, AB yarn color mixing uniformity ≥90%, no obvious color difference and defects;

• Safety indicators: formaldehyde content ≤20mg/kg, heavy metal content in line with national standard limits, no odor and no carcinogenic dyes.

2. Technological innovation direction: research and development of regenerated fiber AB yarn to improve the environmental properties of fabrics; explore intelligent temperature-controlled jacquard fabrics to achieve temperature regulation function by adding phase change materials to expand outdoor clothing application scenarios; optimize jacquard technology to achieve rapid customization of small batches and personalized patterns.

6. Trend Category: Market Development and Industry Direction

1. Trend of appearance: Consumers’ demand for visual personalization of clothing continues to increase. The combination of AB yarn’s mixed color texture and jacquard pattern has become the core selling point of brand differentiation competition, and the demand for customized patterns is gradually growing.

2. Trend of comfortable functionalization: Single and beautiful fabrics are upgraded in the direction of "appearance + comfort + function". The AB yarn jacquard double-sided spandex super-soft fabric with antibacterial, moisture-absorbing and quick-drying properties has further enhanced its market competitiveness.

3. Green environmental protection trend: Driven by the "double carbon" goal, the fabric production process using recycled fibers and environmentally friendly additives is in line with the concept of green consumption and has become the mainstream direction of industry development.
