3 thoughts on “What is the ingening printing process?”

  1. Velvet
    : At present, the fibers used in velvet printing are the most common fibers of sticky, nylon, acrylic, and polyester. Fibrous fibrous fluff can be selected according to the product needs. A nylon or polyester can be used for wear -resistant products. The low cost can be used for adhesive fibers.
    : The specifications of the fluff refer to the length and fineness of the fluff. There is a certain proportion relationship between the two. If this proportional relationship is disordered, it is difficult to plant qualified products. If the fluff is too slender, it is prone to entanglement, and it is difficult to deepen on the adhesive layer during velvet. Conversely, the fluffy hair is too short, the surface of the velvet is rough, and the style is lost. Selection of velvet fiber. The thickness of the fiber is usually represented by Dan (d), and the length is represented by millimeters. Dan is a fibrous unit. How many grams of fiber weight of 9000m is long, and how much its fiber is. The smaller the number, the thinner the fiber.

  2. Velvet printing (static velvet) is a new technology that is currently emerging in the textile industry. It is a product that uses a high -voltage static field to plant short fiber on the gray cloth. Velvet products are simple, three -dimensional, and low in costs. Therefore, it is widely used in rubber, plastic, artificial leather, and decorative products, especially for small batch tourism products. It shows its extremely superiority. The decoration of shifting patterns on shoe caps, children’s clothing, trademarks, and clothing will make its style unique.
    Ip with the industrialization of high -voltage electrostatic processing methods and the development of polymer chemistry, resin adhesive materials used for velvet processing have been rapidly improved, product quality has been improved, and large -area velvet processing processes have also begun to develop from clothing. Its use is very extensive.
    The principle of velvet printing process
    The velvet printing is printed on the surface of the bearing material and applied the fibrous fluffy to the bonding layer to obtain a process method of the flat fabric printing. This process is very distinctive in the printing and dyeing process.
    The static velvet is a process designed by two principles of homosexual reprimation and opposite sex with different charges in a electric field. The high -voltage electrostatic field generated by the electrostatic generator is connected on the metal network with fluff, and one end is connected to the velvet with a gulca. The fluff on the metal network has a negative charge. Due to the attraction of the ground electrode with a positive electricity, it will be accelerated vertically onto the billet cloth that has been applied to the adhesive. It will be attracted to the metal network. The fluff will constantly beating in the electrostatic field until it is evenly filled with velvet on the gray cloth.
    The principle of static velvet is relatively simple, but the technology of static velvet is still in its infancy for my country. It is required to cooperate with the four aspects of electrical, chemistry, fiber, and machinery to process unique velvet products.

  3. Process of the velvet process: coating adhesive → velvet → drying and baking → clearing brush
    (1) The viscosity of the adhesive should be controlled between 15000 ~ 30000CP, the viscosity should In the cloth, the flawed hair adhesion intensity is not enough to fall off; if the viscosity is too low, it is easy to penetrate into the inside of the base cloth. Although the fluff can be pierced into the inner layer of the adhesive, the abrasion resistance is improved, but the feel is harder. Therefore, the thickness of the adhesive layer should be 0.2 to 0.4mm.
    (2) The amount of feldrous gross gifted affects the quality of velvet fabrics, and the density density of the implants is insufficient. Under the action of the electric field, the remaining fluff that is not adhered to the adhesive will continue to fly up and down, affecting indoor cleaning.
    (3) The purpose of pre -drying is to evaporate the organic solvents and water in the adhesive. Generally around 80 ° C. The purpose of baking is to improve the fastness, which can firmly combine the adhesive with the fluff and the base cloth. The temperature is low, and it does not reach the solidity and the temperature is high, resulting in an acidic substance in the catalyst in the adhesive and the vulcanization of the base cloth. The temperature is generally controlled at 150 ± 5 ° C.
    (4) The purpose of clearing the brush is to recycle the floating bristles that are not implanted on the velvet fabric.
