Description

Flocked fusible interlining and manufacturing method thereof

technical field

The present invention relates to performing flocking process on the surface of common spun fusible interlining to form special flocked fusible interlining. Its unique performance brings a new dynamic development market.

Background technique

Flocking technology first started in China more than 3,000 years ago. At first, sticky things like resin were applied to objects, and then wood fibers or other fine powdery things were sprinkled for decoration. This is the prototype of flocking. In modern times, with the needs of social development, flocking technology can be applied to various fields, such as architectural decoration, cosmetics, paper products, jewelry boxes, pencil cases, wine bottles, paper plastic packaging, plush toys, bamboo Wood, textile rolls, bags and more. Of course, the most common is used in the textile field.

Because the flocked items are colorful, soft to the touch and strong in three-dimensionality. According to different needs, the fastness can withstand washing, dry cleaning, and abrasion treatment. Due to the continuous advancement of flocking technology, the application of flocking is very wide. It may be thought that as long as the object can be coated with glue, it can be flocked. If the flocking technology can also be processed on the surface of the woven interlining, Change its previous single style, and combine its color, feel, three-dimensional, comfortable and other characteristics with one body, so that people have a new understanding of interlining.

Contents of the invention

The object of the present invention is to seek a flocking interlining which can combine the characteristics of gorgeous color, soft and comfortable hand feeling and strong three-dimensional effect and its manufacturing method, so as to fully demonstrate its expressive force and tension as an inner lining.

According to the technical solution provided by the invention, the surface of the base cloth is flocked by electrostatic flocking technology, and dotted resin adhesive is coated.

The resin is polyamide, polyethylene, copolyamide, polyester or polyvinyl alcohol resin.

The manufacturing method of flocking fusible interlining, its main features are:

Scouring: Add water and scouring additives to the required amount in the liquid tank of the scouring machine to prepare a scouring liquid. After heating up to 50-70°C, put the base cloth into the liquid tank to make the scouring liquid and the base cloth together in the liquid Rotate circularly in the cylinder, then raise the temperature to a scouring temperature of 80-120°C, after scouring for 15-25 minutes, drain the refining liquid, add cold water to wash and take it out, and then open the scouring base cloth through an open-width machine, and dry it Machine drying, drying temperature is 80 ~ 120 ℃;

Flocking: The refined fabric is put into the flocking machine, and the electrostatic flocking technology is used to plant the fluff on the surface of the base fabric with the aid of flocking additives and voltage;

Finishing: Add water and finishing liquid into the liquid tank of the finishing machine to make the above-mentioned flocked base cloth soaked in the finishing liquid, and then enter the drying and setting machine in the finishing machine for drying. Drying and setting, the drying and setting temperature is: 80-200°C; the speed is 25-40 m/min, so that the fabric is dried and set;

Bonding: Make the base fabric after the above finishing pass through the coating machine, bond point-like resin on the surface of the base fabric, and then set the tenter in the tenter. The tenter temperature is 180-210°C, and the processing speed is: 35- 45 m/min.

The additives in the scouring liquid are composed of 20-40 g/L sodium hydroxide, 10-30 g/L hydrogen peroxide, 4-8 g/L metal ion chelating agent, 1-4 g/L scouring detergent, Desizing agent 4-8 grams/liter, hydrogen peroxide stabilizer 4-8 grams/liter, oxalic acid 2-5 grams/liter, and the rest is water.

Or the ingredients of the additives in the refining liquid are 0.1-0.5 g/L of metal ion chelating agent, 0.1-1.0 g/L of softener in the bath, 0.1-1.0 g/L of surfactant, and 1-5 g/L of sodium hydroxide. liter, desizing agent 0.2-2.0 g/liter, sodium carbonate 1-5 g/liter, and the rest is water.

The flocking method is an electrostatic flocking process, the fluff is viscose or nylon fiber, the auxiliary agent is a crosslinking agent of 0.1-2 g/L, an adhesive of 10-20 g/L, and a catalyst of 0.1-1 g/L;

The amount of additives added in the finishing liquid is 1-5 g/L softener, 1-5 g/L waterproof agent, 0.1-0.3 g/L antistatic agent, 1-3 g/L anti-yellowing agent, and 1-3 g/L anti-yellowing agent. The rest is water.

Or the ingredients of the additives in the finishing liquid are softener A 2-6 g/L, softener B 1-3 g/L, static antistatic agent 1-3 g/L, penetrant 0.1-0.5 g/L, and the rest for water.

Electrostatic flocking technology is used in flocking, using the physical characteristics of the same-sex repulsion and opposite-sex attraction, the fluff is placed in a negatively charged container, so that the fluff is negatively charged, and the base fabric that needs to be flocked is placed on zero. Under the condition of potential or grounding, move the container close to the flocked base cloth, so that a high-voltage electric field is formed between the negatively charged container and the flocked base cloth. The attraction of the flocking base fabric flies to the surface of the base fabric that needs to be flocked. Since the flocking base fabric is coated with flocking additives, the fluff is glued to the flocking base fabric.

When bonding, the primer is evenly coated on the surface of the base fabric in dots by using the method of mesh cylinder transfer, and then the powdery resin is sprinkled, and then the excess resin is absorbed to make the primer on the base fabric. Stick or keep the resin, then heat with infrared, temperature: 220-270°C, make the primer dry and fix on the surface of the base cloth, then enter the drying room to shape the base cloth, the temperature of the drying room is 100-140 °C, the processing speed is 35 ~45 m/min.

When bonding, hot-melt transfer can also be used. There is a hopper filled with powdery resin above the bonding roller covered with pits. The temperature of the bonding roller is 30-40°C. The heating roller is used to heat the base cloth, the temperature of the heating roller is 155-185°C, the bonding roller rotates, the powdery resin falls into the pit of the bonding roller, and immediately becomes molten, so that the base cloth passes through the bonding roller , the resin in the pit will adhere to the surface of the base fabric to form dotted resin, and then be dried and shaped by a tenter car, and the temperature of the oven is 160-200 °C;

During the drying and setting in the finishing process, there are nine drying and setting rooms. The temperature of each room is: the first room is 100-110 °C, the second room is 100-110 °C, the third room is 100-110 °C, and the fourth room is 130-140 °C. ℃, five chambers 150-160℃, six chambers 170-180℃, seven chambers 190-200℃, eight chambers 190-200℃, nine chambers 190-200℃.

The resin may be polyamide resin, polyethylene, copolyamide, polyester, polyvinyl alcohol and the like.

The invention has the advantages of changing the traditional way of processing the interlining and endowing it with a more fashionable sense of the times. It uses traditional polyester spun long fibers as the base fabric, combined with flocking technology, to turn the interlining of the same yarn count into two types with completely different styles. Electrostatic flocking is generally used in the flocking process. Electrostatic flocking is to use the physical characteristics of the same-sex repulsion and opposite-sex attraction. The fluff is placed in a negatively charged container, so that the fluff is negatively charged. The base cloth is placed under the condition of zero potential or grounding, and the container is moved close to the flocked base cloth to form a high-voltage electric field between the negatively charged container and the flocked base cloth. The potential is attracted by the flocking base cloth, and accelerates to fly vertically to the surface of the base cloth to be flocked. Since the flocking base cloth is coated with adhesive, the fluff is vertically stuck on the flocking base cloth. Therefore, electrostatic flocking is a new production process generated by the transformation of the natural characteristics of electric charges. Applying it to textiles not only completely changes the original artistic style, but also gives it a distinctive hand feeling: making a single thin The layer is endowed with a three-dimensional effect. At the same time, the change of color is another major feature brought by flocking: it can express multiple colors in the form of patterns at the same time, giving people completely different visual color effects. The same 30D interlining, flocked and unflocked, are completely different in feel and color. When using interlining processed by flocking process, due to the existence of fluff, the direction of fluff and the pressure of hot rolling should be paid attention to when thermally bonding. If the pressure is too high, the fluff will be flattened and lose its original three-dimensional feel. As for the use part, it can be used on the front and back of the fabric according to the needs to obtain personalized clothing to meet the needs of the constantly updated era. At the same time, it also realizes the breakthrough and practicality of inner lining for external use, which brings a new development direction to the interlining industry.
