Double-sided spandex super soft hot stamping fabric: full analysis of performance, technology and application

Double-sided spandex super soft hot stamping fabric is a new functional fabric that combines the high elasticity properties of spandex, super soft base touch and hot stamping decoration technology. It has the advantages of softness and skin-friendly, elastic fit and beautiful appearance. It has outstanding application value in the fields of clothing, home furnishings, accessories and other fields, and meets the market demand for both fashion and practicality.

1. Principles: Fiber synergy and process mechanism

1. Fiber proportioning principle: The fabric base uses polyester or nylon as the basic raw material, and is blended with 5%-10% spandex fiber. The high elastic recovery of spandex can give the fabric a 30%-50% stretch rate in the transverse direction, and the rebound rate is ≥90%, making up for the lack of elasticity of the basic fiber. At the same time, through ultra-fine denier fiber weaving and soft-skin finishing, it creates a soft and smooth super-soft touch, achieving the dual performance of "elasticity + comfort".

2. Double-sided hot stamping process mechanism: Using the principle of thermal transfer, the hot stamping film with metal coating is attached to the front and back sides of the fabric through high temperature and high pressure (temperature 120-150°C, pressure 0.3-0.5MPa). The metal coating and fabric fiber molecules merge with each other to form a strong golden pattern or pattern, which not only retains the original elasticity of the fabric, but also gives it a bright metallic luster.

2. Technology: core processes of weaving and finishing

1. Super-soft base weaving process: Double-sided circular knitting is used to precisely control yarn tension and stitch length to ensure uniform texture and consistent touch on both sides of the fabric. After weaving is completed, it is pre-shrunk and shaped to eliminate internal stress, stabilize the width and weight of the fabric, and avoid deformation in the subsequent hot stamping process.

2. Key processes of double-sided hot stamping

• Pre-treatment of hot stamping: perform static electricity elimination and cleaning treatment on the base fabric to remove surface dust and hairiness and improve the adhesion of the hot stamping film;

• Precise hot stamping: adjust the temperature, pressure and speed of the hot stamping machine according to the pattern requirements to avoid problems such as the hot stamping layer falling off and the pattern being blurred;

• Post-styling treatment: After the hot stamping is completed, low-temperature setting is performed to further strengthen the bond between the hot stamping layer and the fabric while retaining the elasticity of the fabric.

3. Key points of the environmentally friendly process: Use formaldehyde-free, low-VOCs hot stamping films and adhesives, comply with OEKO-TEX® Standard 100 certification standards, and follow green production standards throughout the process.

3. Application Category: Multi-scenario adaptation fields

1. Apparel field: suitable for making fashionable sweatshirts, dresses, yoga pants, stage costumes, etc. The super soft touch improves wearing comfort, the elastic properties meet the needs of body extension, and the hot stamping pattern enhances the visual appeal of the clothing, making it suitable for daily wear and performance scenes.

2. Home and accessories field: It can be used for pillowcases, curtains, tablecloths and other household items. The hot stamping elements enhance the style of home decoration. It can also be used to make accessories such as bags, shoes and hats, and hair accessories. With its eye-catching appearance and durable properties, it has become the preferred fabric for fashion accessories.

3. Children's clothing field: Fabrics using environmentally friendly hot stamping technology can be used to make children's coats, dresses, etc. The soft and elastic properties are suitable for children's activity needs. The eye-catching hot stamping design is loved by children and complies with the safety standards for infant and child textiles.

4. Maintenance: washing and maintenance skills

1. Washing specifications: It is recommended to hand wash in cold water, or put it in a laundry bag and choose the gentle machine wash mode. The water temperature does not exceed 30°C. Use neutral detergent and avoid using bleach, strong acid and alkali detergents to prevent the oxidation of the bronzing layer and the attenuation of the fabric's elasticity.

2. Drying and storage: After washing, gently squeeze out the water, lay flat to dry in the shade or hang to dry, avoid exposure to the sun to prevent fading and cracking of the hot stamping layer; fold flat when storing, do not press or rub the hot stamping parts, store separately, avoid contact with sharp objects.

3. Ironing precautions: Try to avoid ironing; if you need to iron, turn the fabric over, set the low temperature mode (temperature ≤ 110°C), keep the iron 5-10cm away from the fabric for steam ironing, and do not allow direct contact with the hot stamping layer.

5. Technology: core performance indicators and innovation directions

1. Core performance indicators

• Elasticity index: transverse stretch rate 30%-50%, rebound rate ≥90%, no obvious deformation after multiple stretches;

• Firmness index: The hot stamping layer can be washed ≥20 times, the rubbing fastness is ≥3, and there is no obvious shedding;

• Safety indicators: formaldehyde content ≤75mg/kg, heavy metal content in line with national standard limits, no odor.

2. Technological innovation direction: Research and develop new hot stamping processes such as laser hot stamping and gradient hot stamping to enrich the visual effects of patterns; explore highly elastic and washable hot stamping adhesives to improve the durability of the hot stamping layer; combine antibacterial, sun protection and other functional finishing to expand the application scenarios of fabrics.

6. Trend Category: Market Development and Industry Direction

1. Fashion trend: Consumer demand for the appearance of clothing continues to increase. Fabrics with both soft elasticity and eye-catching hot stamping effects have become a key purchasing category for fashion brands. Personalized hot stamping pattern customization will become a competitive highlight in the industry.

2. Functionalization trend: Single decorative hot stamping fabrics are gradually developing towards multi-functionality. Double-sided spandex super-soft hot stamping fabrics that incorporate antibacterial, moisture-absorbing, quick-drying, anti-static and other properties will further enhance their market competitiveness.

3. Environmental protection trend: Driven by the concept of green consumption, fabrics using environmentally friendly bronzing materials and production processes meet the market's environmental protection needs and will become the mainstream direction of industry development.
