Recently, Germany developed and launched a new concept textile material for dralon ultra-fine, shaped acrylic fiber . Dralon fine denier shaped acrylic fiber, originated from the German dry spinning technology, the fiber has a dumbbell (dog bone) shaped heterosexual cross-section, the fiber surface and the interior are very few holes, the fiber fineness of 0.6dtex ~ 0.9dtex. Dralon ultra-fine acrylic fiber surface smooth, cross-sectional dumbbell-shaped, so that the fiber feels both soft and cool, good coverage, fluffy plump, strong water, dry breathable, comfortable to wear, easy to dye, bright colors, elegant gloss, like Wool, anti-sun, good weather resistance and anti-mildew properties. Dralon fine-denier acrylic fibers are widely used in apparel and home textiles, and the market is very promising. Recently, Germany dralon cotton, ultra-fine, shaped acrylic fiber in the only designated distributor in China, Shanghai Risoo Technology Textile Co., Ltd. held a promotion meeting in Shanghai Textile Research Institute, to introduce the participants dralon ultrafine acrylic fiber products The characteristics have aroused great interest of the participants. Unlike Nissan's round or bean-shaped cross-sections, the dralon's ultra-fine acrylic cross-section is double T-shaped, which is why it has several characteristics. The axial ratio of dralon ultrafine acrylic cross-section is approximately 3:1 to 2:1, and the flexural modulus of the fiber along the axis is approximately one-half of that of the circular cross-section. This feature is advantageous for weaving sweaters and hosiery fabrics. value. The elastic recovery rate of dralon ultra-fine acrylic fiber when stretched 1% to 3% is 99%, 90% to 95%, curl elasticity is 85% to 95%, and the fiber modulus is higher than that of Nissan, which is 33.5cN to 46.1 cN/dTex makes it soft and has high elasticity and modulus. Therefore, compared with Nissan Acrylic, German dralon superfine acrylic fiber performance is closer to wool. Due to its double T-shaped cross-section, dralon ultra-fine acrylic fibers are different in the arrangement of individual fibers in the fiber group and in the circular cross-section of Nissan Acrylic Fiber. The fibers do not easily gather together and the air between the fibers is filled with an insulating layer. , In order to make it have a good fluffy, covering and warmth, thermal insulation performance per unit weight is 20% higher than wool. Compared with the Nissan acrylic with circular cross-section, the acrylic yarn developed by the German company is 30% higher in bulkiness, 10% higher in bulkiness, and can be reduced by 10% with the same coverage and heat preservation effect. The left and right fibers reduce the weight of the fabric accordingly. German dralon ultra-fine acrylic fiber because of its slow fiber forming process, fiber cross-section structure inside and outside the uniform dense, so that the fiber has good physical and mechanical properties and dyeing properties. Nissan has voids and crevices inside it. Although it is strictly stretched and densified, its fiber elasticity, hooking strength, gloss and other indicators are inferior to it. The elasticity of German dralon ultra-fine acrylic fiber is about 10%~20% higher. Generally, the hook strength is about 60% of dry strength, while the daily production of acrylic fiber is between 40%~45%. German dralon ultra-fine acrylic uniform cross-section structure, but also makes the fiber has a unique thermal shrinkage properties. The fiber shrinks when it is hot and humid at 100°C. Therefore, this fiber does not have to be treated with high-temperature acrylic fiber during post-processing (Nissan Acrylic usually produces significant shrinkage under a vapor pressure of 1.96×105 Pa.) This is The conditions for the diversification of color varieties in textile processing are provided. Surface morphology is an important form of acrylic content. German dralon ultra-fine acrylic fiber is slowly formed in a hot inert gas flow without contact with the coagulation bath. The resulting fiber not only has a uniform and compact cross-section structure, but also has a fiber surface that is different from that of Nissan Acrylic Co. The fiber has elegant gloss, good elasticity and resilience, and the fabric has the style of animal skin. Because the surface of the fiber is smooth, the fiber can effectively and evenly adhere to the surface of the fiber during the post-treatment process, and the amount of the oil agent is less than that of the Nissan Acrylic Fiber, and the fiber style does not change much after repeated washing. There is a large capillary zone between the filaments of dralon ultrafine acrylic fibers. In addition to its excellent fluffy and warmth properties, it also has superior moisture wicking ability, which allows the fabric to quickly remove the humidity generated by the body. Avoid the cold feeling.
