Double-sided spandex super soft cut fabric: full analysis of characteristics, technology and applications

Double-sided spandex super-soft cut-out fabric is a high-end knitted fabric that integrates double-sided three-dimensional patterns, high-elastic fit performance and soft and skin-friendly texture. Through the combination of cut-out technology and spandex blending technology, it achieves double breakthroughs in appearance and practicality. It has significant application advantages in the fields of mid-to-high-end clothing and home textiles.

1. Principles: Fiber synergy and shearing mechanism

1. Fiber proportioning principle: The fabric base uses ultra-fine denier polyester or nylon as the main raw material, and is blended with 6%-10% spandex fiber. The high elastic recovery of spandex gives the fabric a stretch rate of 30%-50% in the transverse direction, and a rebound rate of ≥90%, which solves the pain points of traditional cut fabrics with poor elasticity and easy deformation; after the ultra-fine denier fiber is softened, it feels delicate and soft to the touch, achieving the fusion of "elastic support + super soft skin-friendly" performance.

2. Principle of the double-sided shearing process: Based on the combined technology of jacquard weaving and shearing finishing, a gray fabric with floating thread patterns is first woven through a double-sided jacquard machine, and then high-precision shearing equipment is used to accurately cut the floating thread yarns on the surface of the fabric, so that both the front and back sides of the fabric form a three-dimensional shearing pattern with distinct concavities and convexities at the same time. The pattern is closely connected with the fabric fibers and is not easy to fall off, and the breathability and layering of the fabric are significantly improved after the pattern is cut.

2. Technology: core processes of weaving and finishing

1. Double-sided jacquard gray fabric weaving

• Yarn preparation: Select high-tenacity main yarn and spandex bare yarn to ensure uniform yarn twist and avoid breakage during weaving;

• Jacquard weaving: debug the pattern program of the double-sided jacquard machine, accurately control the knitting needle movement trajectory of the dial and needle cylinder, so that the position and density of the floating thread patterns on the front and back sides are completely matched; stabilize the yarn tension during the weaving process to prevent defects such as missing stitches and jumpers, and weave basic gray fabrics.

2. Cut flowers and super soft finishing

• Precise flower cutting: Use a computer numerical control shearing machine, set the shearing depth and speed, only cut off the floating thread part, and retain the basic structure of the fabric to ensure that the edges of the cutting pattern are clear and the three-dimensional effect is strong; after cutting, suction is performed to remove short threads remaining on the surface of the fabric;

• Softening and shaping: Dip the cut-out gray fabric into a formaldehyde-free environmentally friendly softener, and make the softener fully adhere to the fiber surface through padding and drying processes; then set it through low-temperature hot air at 120-130°C to eliminate the internal stress caused by weaving and cutting, stabilize the width and weight, and retain the elastic properties of spandex;

• Quality inspection: The finished product is tested for pattern clarity, elastic recovery rate and other indicators to ensure that the double-sided cutting effect is consistent and there are no obvious color differences and defects.

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 dresses, sweatshirts, home clothes, thermal underwear, etc. The double-sided cut-out three-dimensional pattern enhances the fashion sense and recognition of the clothing. The 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 princess skirts. The safe and skin-friendly characteristics meet the needs of children's skin.

2. In the field of home textiles: it can be used to make pillowcases, sofa covers, bedding sets, curtains and other soft furnishing products. The double-sided cut-out layering adds a light and luxurious texture to the home space. The 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 the double-sided cut flowers enhances the beauty 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 the fabric from fading and elasticity attenuation; when machine washing, the fabric needs to be turned over to reduce friction damage to the cut pattern.

2. Drying and storage: After washing, gently squeeze out the water, lay it flat to dry in the shade or hang to dry, avoid exposure to the sun, and prevent ultraviolet rays from hardening the fabric and deforming the cut pattern; fold it flat when storing, do not put heavy pressure on the cut parts, and store it 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 prohibit the iron from directly contacting the cut pattern to prevent the pattern from collapsing.

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;

• Cutting fastness index: washing fastness ≥ level 4, rubbing fastness ≥ level 3, there is no obvious shearing or deformation of the cutting pattern after 20 times of washing;

• 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 develop new processes such as gradient cut-outs and hollow cut-outs to enrich the visual hierarchy of patterns; explore cut-out fabrics based on recycled fiber to improve the environmental attributes of products; combine antibacterial, constant temperature and other functional finishing to expand the application of fabrics in outdoor, medical and other fields.

6. Trend Category: Market Development and Industry Direction

1. Personalized customization trend: Consumers’ differentiated demand for clothing is increasing. Customized cut patterns and fabrics with niche design styles have become the core selling points of brand competition. Small batch and quick-turn production models are gradually becoming popular.

2. Trend of functional compounding: single decorative cut-out fabrics are being upgraded in the direction of "appearance + function". Market demand for double-sided spandex super-soft cut-out fabrics that incorporate antibacterial, moisture-absorbing, quick-drying, anti-static and other properties will continue to grow.

3. Green environmental protection trend: Driven by the "double carbon" goal, cut fabrics using recycled fibers and environmentally friendly additives are in line with the concept of green consumption and have become the mainstream direction of industry development.
