Such buttons are often buttons that are pigmented directly into the resin and injected into various colors. When the batch size of the buttons is large and the color has been determined before production, the method of premixing the coloring of the pigment is often used. The advantage of using this method is that relatively inexpensive plastics can be selected to reduce costs and facilitate injection molding. Commonly used plastics for pigmented plastic buttons are polypropylene, ABS, etc. The main advantage of using polypropylene plastic is that this kind of material is low in price, low in mold requirements, good in injection molding technology, and excellent in corrosion resistance of injection molded products (almost resistant to most organic solvents and acid and alkali corrosion). The mechanical properties are better. In addition to polypropylene, ABS is also often used to produce colored plastic buttons, but ABS is more expensive than polypropylene and inferior in organic solvent resistance than polypropylene. In general, the overall performance of ABS coloring buttons is not as good as that of polyethylene, so it is not widely used.

High-quality and comfortable fabrics are selected for children's clothing. The products are mainly high-count combed cotton, supplemented by other silk, wool and blended fabrics. In order to completely isolate the baby's delicate skin from the spandex yarn, the reverse bottom is used as the surface process. The inner and outer layers of the fabric are cotton threads, and the middle layer is elastic spandex yarn, which doubles the elasticity of the fabric, and the skin is not tight and the skin has zero contact with chemical fibers. Strictly control the printing, dyeing and other technological processes, and use environmentally friendly dyes to ensure that every small piece of clothing is given natural and healthy care for children.
