The birth of the five-pointed star printed mink fabric began with the strict selection of raw materials. 90% of the mink raw materials on the market come from Denmark and Finland. The mink harvested in winter is the first choice because of its high density of down and short and fine needle hair. Most of the imported velvet-grade mink fur is female mink, and its base density can reach 1.5 times that of ordinary mink fur, and it feels light and soft; while the imported crown-grade mink fur is characterized by short and dense needle hair and thick base hair. The combination of the two forms the basic skeleton of the fabric.
Tanning technology is the cornerstone of fabric quality. The raw mink fur needs to go through more than 20 processes such as pickling, drying, drumming, fattening, and shaving. In the pickling process, the mink fur is soaked in 1:150 salt water for 2 hours, and then mixed with sawdust in a drum to loosen the hair. The fattening process requires strict control of the ratio of oil to flour (5 kg of oil to 5 kg of flour) to ensure that the leather is flexible and not stiff. During the dyeing stage, the addition of retanning chemicals and leather green can improve the temperature resistance of mink fur, and the dyeing temperature needs to be precisely controlled at around 50°C to ensure color uniformity.
Printing technology is the core of fabric design. Traditional fur printing mostly uses spray ridge and carving technology, while the presentation of the five-pointed star pattern relies on high-precision digital printing equipment. Designers need to decompose the five-pointed star pattern into a vector file through CAD software, and then use thermal transfer technology to penetrate the pattern into the surface of the mink fur. This process requires that the corners of the five-pointed star are precisely aligned with an error of no more than 0.1 mm, while avoiding destroying the natural luster of the mink fur.
The performance of the five-pointed star printed mink fabric comes from the ultimate control of process parameters. The density of the base must reach the standard of short-hair velvet, that is, the hair is upright and can recover quickly after being blown by air; the length of the needle hair must be controlled within the crown level range, which not only ensures the delicate feeling of the short hair, but also avoids the prickly feel caused by too long. Under a microscope, the gap between the pile of high-quality fabrics is less than 0.05 mm, forming a velvet-like touch.
The presentation effect of the five-pointed star pattern depends on the color saturation and positioning accuracy. Laboratory tests show that when the black component in the CMYK color value of the five-pointed star exceeds 60%, the contrast of the pattern on the mink surface is the best. At the same time, the thermal transfer temperature must be precisely controlled at 180℃±5℃ for no more than 12 seconds to prevent the leather board from shrinking or the pattern from blurring. In addition, the wear resistance of the fabric is verified by the Martindale wear test, and its number of revolutions can reach more than 20,000 times, far exceeding ordinary printed fabrics.
Wrinkle resistance and breathability are key indicators for measuring the practicality of fabrics. The five-pointed star printed mink fabric adopts a combination of "smooth and reverse hair" technology to make the hair surface present a wavy texture in a natural state, thereby reducing wrinkles. The breathability test shows that the air permeability per unit area of the fabric can reach 0.5L/m²·s, ensuring wearing comfort.
The innovation of mink fabric with five-pointed star print is essentially a dialectical unity of technical logic and artistic expression. From a technical perspective, its process needs to solve three major contradictions: one is the balance between tanning softening and leather toughness, the second is the coexistence of dyeing uniformity and natural luster of the fluff, and the third is the coordination of printing accuracy and fabric flexibility. For example, in the fat-adding process, if the proportion of oil is too high, the leather will be too soft and affect the printing accuracy; if the proportion is too low, the leather will be stiff and easy to crack.
In terms of artistic expression, the geometric aesthetics of the five-pointed star pattern and the natural texture of the mink fabric form tension. Designers give fabrics different visual languages by adjusting the size, spacing and arrangement of the five-pointed stars. For example, the five-pointed stars arranged at equal distances form a sense of order, which is suitable for business formal wear; while the five-pointed stars distributed randomly create an artistic atmosphere, which meets the needs of casual wear. In addition, the chamfer design of the five-pointed star (roundness of the corners) directly affects the affinity of the fabric. The rounded five-pointed star is softer and suitable for women's clothing; the right-angled five-pointed star is more powerful and suitable for men's clothing.
The application scope of the five-pointed star printed mink fabric is far beyond the scope of traditional fur clothing. In the fashion field, it is used to make coats, shawls, accessories and other items. For example, a brand launched a short two-hair five-pointed star printed mink coat. The thickness of the base velvet is 0.2 mm through the "garlic velvet" process, and the 0.2 mm hair needles of the black Blackglama mink form a layered visual effect. In the home furnishing field, this fabric is used in soft furnishings such as pillows and carpets. Its wear resistance and stain resistance (treated with Teflon coating) meet the needs of daily use.
