Double-sided striped baby fleece: a complete guide to characteristics, processes and applications

Double-sided striped baby velvet is a knitted fabric specially designed for infants and close-fitting wearing scenarios. It combines the three-dimensional texture of double-sided striped baby velvet with the soft and skin-friendly properties of baby velvet. It has a delicate and fluffy touch, is warm and breathable, and meets the wearing needs of infants and children with delicate skin and high activity. It has significant application advantages in the fields of children's clothing and maternal and infant home textiles.

1. Principle Category: Fiber Characteristics and Structural Mechanism

1. Principle of fiber selection: The core raw material of the fabric is ultra-fine denier polyester fiber or modified polyester fiber. The fiber fineness is lower than that of conventional textile fibers, and the diameter can reach the micron level. It feels soft and non-itchy. It also has good moisture absorption and perspiration properties, which can quickly conduct sweat away from the skin surface and keep the skin dry. Some high-end products will add a small amount of viscose fiber to further improve skin-friendliness.

2. Principle of double-sided strip structure: It is woven using a double-sided knitting machine. By adjusting the arrangement of the needle bed and the needle trajectory, regular longitudinal strip textures are formed on both the front and back sides of the fabric at the same time. The strip spacing is even and the texture is three-dimensional. Compared with ordinary plain baby velvet, the striped structure increases the breathability and stretchability of the fabric, while also enhancing the fabric's anti-pilling performance and making it less likely to deform and wrinkle.

2. Technology: core processes of weaving and finishing

1. Double-sided strip weaving process: Before weaving, it is necessary to accurately adjust the stitch length and yarn feeding tension of the knitting machine to ensure that the striped lines on the front and back are symmetrical and consistent; low elasticity or ultra-fine denier fiber yarns are used for weaving. After weaving the gray fabric, it needs to be preshrunk to eliminate the internal stress generated during the weaving process, stabilize the fabric size, and avoid serious shrinkage in subsequent washing.

2. Velvet-feel finishing process: After the gray fabric is pre-shrunk, it is raised and sanded to form a layer of fine short velvet on the surface of the fabric to improve the softness to the touch; it is then treated with antistatic and antibacterial finishing, and special environmentally friendly additives for infants and children are added to eliminate harmful chemical residues and comply with the national infant and child textile safety standards GB 31701-2015 Class A requirements.

3. Key points of the shaping process: The finished product is shaped using low-temperature hot air, and the temperature is controlled at 120-140°C to avoid high temperature damage to the fiber structure. At the same time, it ensures that the three-dimensional sense of the drawing lines is not destroyed, and the stretch and resilience of the fabric can reach a good state.

3. Application Category: Multi-scenario adaptation fields

1. Infant and child clothing field: It is the preferred fabric for baby onesies, rompers, thermal underwear, and coats. Its soft and skin-friendly properties are suitable for the delicate skin of infants and children. The three-dimensional striped structure is breathable and does not make people sweat. The elasticity can meet the baby's needs for activities such as turning over and crawling, and it is not easy to cause friction and damage to the skin.

2. Maternal and infant home textiles: It can be used to make baby pillowcases, blankets, sleeping bags, crib sheets and other products. The fluffy and warm touch can create a comfortable sleeping environment for babies. The antibacterial and antistatic properties can reduce the risk of skin allergies for babies.

3. Adult intimate apparel field: It can also be used for adult thermal underwear, home clothes, pajamas, etc. It is suitable for people with sensitive skin. Its soft touch and good warmth retention meet the current comfort needs of adults for intimate apparel.

4. Maintenance: washing and maintenance skills

1. Washing specifications: It is recommended to hand wash with warm water below 30℃, or put it in a laundry bag and choose the gentle machine wash mode; use a neutral detergent specifically for infants and children. It is forbidden to use bleach and softener to avoid damaging the antibacterial layer and velvet feel of the fabric.

2. Drying and storage: After washing, gently squeeze out the water and lay it flat to dry in the shade. Avoid exposure to the sun and high temperature drying to prevent the fabric from fading and hardening the velvet feel. When storing, fold it flat and do not stack it under heavy pressure to avoid deformation of the stripes. For long-term storage, put it in a breathable storage bag to prevent moisture and mildew.

3. Note on ironing: The fabric itself is soft and fluffy, so there is no need to iron it; if wrinkles appear due to storage, you can use low-temperature steam ironing. The iron should be 10-15cm away from the fabric to avoid direct contact with the suede surface.

5. Technology: core performance indicators and innovation directions

1. Core performance indicators

• Safety indicators: Comply with GB 31701-2015 Class A standard, formaldehyde content ≤20mg/kg, heavy metal content below the national standard limit, no odor, no carcinogenic dyes;

• Functional indicators: Antibacterial rate ≥99% (against Staphylococcus aureus, Escherichia coli), excellent antistatic properties, triboelectric voltage.

2. Technological innovation direction: Research and develop double-sided striped baby velvet made of degradable fiber material to improve the environmental protection properties of the fabric; integrate constant temperature and humidity control technology to adapt the fabric to different seasons; optimize the design of the striped structure to further enhance the breathability and anti-pilling performance of the fabric.

6. Trend Category: Market Development and Industry Direction

1. Safety trend: The safety standards of infant and child textiles continue to upgrade. Double-sided striped baby velvet that meets Class A standards and has no additives has become a core consideration for parents when purchasing, and market demand is growing steadily.

2. Functionalization trend: Baby velvet fabrics with composite functions such as antibacterial, anti-mite, and constant temperature can meet the diversified needs of parents for infant and child clothing and are the research and development focus of fabric companies.

3. Environmental protection trend: With the popularization of the concept of green consumption, double-sided baby fleece made of recycled fibers and degradable raw materials will become the mainstream direction of industry development and meet the sustainable development needs of the maternal and infant market.
