 Preparation method of polyester-polyamide composite microfiber terry cloth and terry cloth thereof

 The invention relates to a preparation method of a polyester/polyamide composite microfiber terry cloth and a terry cloth thereof, belonging to the field of textile products. Background technique

 As we all know, the traditional towel uses natural fiber-cotton fiber. The cotton fiber is easy to breed bacteria in a humid environment, causing mildew, and it is easy to produce hair loss and harden after washing.

 Microfiber has the characteristics of super absorbent, no lint, mildew, no odor, strong softness, no fading, easy to clean dirt, anti-chlorine bleaching, anti-oxidation bleaching, etc. It has a wide range of applications in car maintenance. , hotel industry, beauty salons, sporting goods, daily necessities and other fields have excellent performance, such as towels, bath towels, dry hair shower caps, beauty cleansing towels, household clean rags, car rags and so on.

 The advantages of the microfibers are as follows: The specific surface area of the microfibers is large, so that the coverage of the microfiber fabric is extremely high, the specific surface fibers are more frequently contacted with dust or oil, and the oil is infiltrated from the gap between the fiber surfaces. More, it has a very strong cleaning function. Microfiber fabric can penetrate deep into the pores of the skin and effectively remove dirt, grease, dead skin and cosmetic residues. Microfibers have small bending stiffness due to their small diameter. The fiber feels particularly soft; the ultra-fine fiber is made into an ultra-high-density fabric, and the gap between the fibers is between the diameter of the water droplet and the diameter of the water vapor droplet, so that the ultra-fine fabric has a waterproof and vapor-permeable effect; and can overcome the wrinkle of the natural fiber, The shortcomings of man-made fibers are not breathable; the durability is more than four times that of ordinary fabrics, so microfibers have broad application prospects.

 Polyester/polyamide composite microfiber is made up of two kinds of high polymer melts of polyester fiber and nylon fiber. It is divided by a special distribution plate and extruded through the same orifice. The surface of the fiber has a bell-shaped shape and a rice shape. After the weaving of the fabric, it is necessary to open the fiber at 110 °C with about 5% of the alkali solution, so that the two components of the polyester and the brocade are peeled off to form the ultrafine fiber. The ordinary microfiber terry cloth structure is a double-sided or single-faced terry structure. After a chemical opening, the thickness of each fiber is only 0.1D. The friction is very large during use, which is very embarrassing and easy to scratch. The feeling of being uncomfortable, especially when the skin is rough, is more obvious, which restricts the further development of the microfiber terry cloth.

Patent CN200910260596.8 describes a method for raising artificial leather, which is subjected to sanding on one or both sides of a microfiber polyurethane synthetic leather, and the surface of the polyester microfiber and the polyamide microfiber 撅Forming polyester fluff and polyamide fluff, this sanding process can maintain the overall performance of the two microfibers at the same time, so that the final product has both stiffness and softness while having a delicate hand. This method of raising is directed to flat cloth raising, which only grinds the surface of the fiber. In addition, this product is completely different from the terry cloth structure of the present invention, and its use is completely different, and its essence is completely different from the technical solution of the present invention. Literature (Li Weiyong. Development of Haiyidao Microfiber Flocking Products [J]. Silk, 2004 (12): 7-9), according to the style of Haiyidao microfiber fleece products, optional Corresponding sanding parameters. The main factors affecting the grinding effect are: sandpaper mesh, grinding roller speed, coating angle, fabric running speed, fabric moisture content and post-grinding treatment. The operation process during the grinding process is very important for the appearance effect and style of the fabric. The machine performance and the grinding effect to be achieved should be mastered, and the process should be adjusted at any time according to the situation. If new sandpaper is used, the wrap angle should be small and the speed should be fast. With the prolonged use time and the loss of sand on the sandpaper, the wrap angle and tension should be gradually increased to reduce the speed of the fabric and keep the surface of the fabric after grinding. Consistent fluff effect. Grinding process: sandpaper mesh number 240~280#, sandpaper speed 800~1000r/min, speed 20~25m/min. This method of raising is also directed to flat cloth raising, which also grinds the surface of the fiber. Moreover, this product cannot be used as a terry cloth, and can only be used in the fields of decorative cloth, shoe-making industry and clothing industry, and the technical solution of this product is completely different from the technical solution of the present invention.
