The uses of acrylic fiber include: acrylic fiber can be blended with wool to make wool, blankets or carpets, and can also be blended with man-made fiber, cotton and other synthetic fibers to make various clothes and indoor articles; The bulky top processed by acrylic fiber can be spun pure or blended with viscose fiber and wool to make various medium-coarse and fine cashmere yarns. Acrylic fiber is mainly used in clothing, various dressing and industrial fields. Advantages of acrylic fiber: The performance of acrylic fiber fabric is similar to that of wool, but its elasticity is much better than that of wool. With an elongation of 20%, the rebound rate can still be maintained at about 65%. Acrylic fabric is better than wool in thermal insulation. Acrylic fiber is loose and curly in shape, and feels very soft. Therefore, thermal insulation is much better than wool fabric. It was once said that synthetic wool. The strength of acrylic fabric is higher than that of wool. At present, the strength of acrylic fiber is about 22.1~48.5CN/DTEX, while that of wool is about 1 to 2.5 times lower than that of acrylic fabric. Acrylic fiber has a strong resistance to sunlight, which means that it has a good resistance to sunlight. If you expose acrylic fiber in the sun, there will be no problem at all. Some experiments have shown that the strength of articles made of acrylic fabric has only decreased by less than 20% after exposure to the sun for one year, which shows how useful it is. Products made of acrylic fabric are generally not afraid of acid attack, and have excellent resistance to acid, oxidant and general organic solvents. Disadvantages of acrylic fiber: the alkali resistance of acrylic fiber fabric is poor. If you use alkaline cleaning products when washing, you should pay attention to it. At the same time, higher temperature will also have a greater impact on the acrylic fiber fabric. At a high temperature of 190 to 230 degrees, the acrylic fiber of women's clothing fabric will soften. In addition, the moisture absorption of acrylic fabric is also relatively poor. Acrylic fiber belongs to short fiber, and short fiber is simple pilling. Therefore, the poor quality acrylic fabric has small pompons after a long time, which is very ugly. So now many acrylic sweaters will be mixed with some wool to prevent pilling.
