Microfiber Recently Released In Germany

Recently, Germany has developed and launched the new concept of dralon superfine and profiled acrylic fiber. raw material 。 Dralon fine denier acrylic fiber originates from German dry spinning technology. The fiber has a cross section of dumbbell (Gou Gu) shape, and the fiber surface and interior are very few pores, and the fineness of fiber is 0.6dtex ~ 0.9dtex. Dralon super fine acrylic fiber has smooth surface and dumbbell shaped cross-section, which makes the fiber feel soft and smooth, good coverage, fluffy and full, water conveying strong, dry and breathable, comfortable to wear, easy to dye, brightly colored, glossy and elegant, similar to wool, anti sun drying, good weather resistance and mildew proof and moth proof performance. Dralon fine denier acrylic fiber textiles are widely used in clothing and home textiles, and the market development prospects are very promising. A few days ago, the German dralon cotton type, superfine and special acrylic fiber was designated as the sole distributor in China. Shanghai Ru Shu technology Textile Co., Ltd. held a promotion conference at Shanghai Textile Research Institute. It introduced the product characteristics of dralon superfine acrylic fiber to the participants and aroused great interest of the participants.

Different from the round or bean shaped section of Nissan acrylic fiber, the cross-section of German dralon superfine acrylic fiber has double T shape, which has some characteristics. The axial ratio of dralon superfine acrylic fiber is about 3: 1~2: 1, and the bending modulus of the fiber is about 1/2 of the circular cross section. This characteristic is of great value for weaving sweaters and socks. The elastic recovery rate of dralon superfine acrylic fiber at 1% and 3% elongation is 99%, 90% ~ 95%, the crimp elasticity is 85% to 95%, and the fiber modulus is higher than that of Nissan acrylic fiber, which is 33.5cN ~ 46.1cN/dTex, making it both soft and high elasticity and modulus. Therefore, compared with Nissan acrylic fiber, German dralon superfine acrylic fiber is closer to wool. Because of the double T section of dralon superfine acrylic fiber, the arrangement of the single fiber in the fiber group is different from that of the Nissan acrylic fiber with circular cross section. The fibers are not easily aggregated together, and the fibers are filled with air, forming an insulating layer, so that it has good fluffiness, coverage and warmth retention. The heat preservation performance of the unit weight is 20% higher than that of wool. Compared with the Nissan acrylic fabric with circular cross section, the yarn developed by Germany is 30% higher and the bulkiness is 10%. Under the same covering rate and heat preservation effect, the fiber can be reduced by about 10%, and the weight of the fabric is lightened accordingly.

German dralon superfine acrylic fiber is slow due to its forming process. fibre The cross section structure is uniform and dense inside and outside, so that the fibers have good physical and mechanical properties and dyeing properties. Nissan acrylic fiber internal cavity, gap, although strictly stretched and densified treatment, its fiber elasticity, hook, luster and other indicators are not as good as it. The elasticity of German dralon superfine acrylic fiber is about 10%~20% higher than that of Germany, and its strength is about 60% of dry strength, while Nissan acrylic is between 40%~45%. The uniform and dense cross-sectional structure of dralon superfine acrylic fiber in Germany also makes the fibers have unique thermal shrinkage properties. The fibers shrink when they are wet and hot at 100 degrees, so the fibers do not have to be treated at high temperatures such as Nissan acrylonitrile in the post-processing process (Nissan acrylic fibers usually contract significantly below 1.96 * 105Pa vapor pressure). This provides conditions for the diversification of colors and patterns in textile processing.

Surface morphology is an important form of acrylic fiber structure. The German dralon superfine acrylic fiber is formed slowly in the hot inert airflow without contacting with the coagulation bath. The fibers obtained are not only uniform and dense in cross-section structure, but also different from the wrinkle roughness of Nissan acrylic fiber, but the fiber surface is very smooth. The fiber is glossy, elegant, elastic and resilient, and the fabric has a skins style. Because the surface of the fiber is smooth, the oil can be effectively attached to the fiber surface in the post-processing process, and the dosage of the oil is less than that of Nissan acrylic fiber. There is a large capillary zone between the inner filament of dralon superfine acrylic fiber. Besides the excellent fluffy and warmth retention properties, it has superior water wicking ability. Textile The moisture generated by the body can be dredging out faster to avoid the feeling of damp and cold.
