The method of short fiber (generally 0.03 ~ 0.5cm) is called velvet velvet vertically on the substrate with adhesive. The woolen velvet is to fix the vertical wool to the substrate with adhesive. The principle of velvet implants is to use the physical characteristics of the charges of homosexuality to reprimand the opposite sex, so that the velvet is negatively charged. Put the object that needs to be implanted under zero potential or ground conditions. The attraction is accelerated vertically to the surface of the object that needs to be demented. Because the plant is coated with a adhesive, the fluff is stuck vertically on the plant. This: Strong three -dimensional sense, bright colors, soft feel, luxurious and noble, gorgeous and warm, realistic, non -toxic and tasteless, insulation and moisture prevention, not deserted, friction resistance, flat without gap. The surface of various product substrates can be implanted, and it is not limited by the shape and size of the plant body. Such as: paper, cloth, non -woven fabric, artificial leather, plastic, glass, metal, rubber, wood plate, sponge, gypsum board, artificial board, plastic film, foam, ceramic, resin, etc.
This in the velvet industry is very broad, representative industry: 1, craft industry: toys, crafts, photo frames, gifts, craftsmanship, people, people, people, people, people, and people Flowers, craft plastic lanterns, etc. 2, packaging industry: jewelry box, health product packaging box, wine box, glasses box, wedding certificate, high -end certificate epidermis, wine bottle, luggage, non -dry glue, paper skin (board), etc. 3, automobile industry: automobile rubber sealing, car interior plastic parts, etc. 4, other industries: motorcycle helmets, hanging hams, fire doors, safe, lamps, cabinets, sanitary ware, furniture, sponges, EVA, various materials, etc. 5, resin, ceramic, gypsum, glass, plastic, regenerative plastic crafts, toy surface velvet. Pucting data The selection of velvet fabrics The n because of the knowledge involved in electrochemicals to ensure the best quality of velvet products. Critical. 1, velvet nylon fiber and sticky glue are the most commonly used sticky glue. Its raw materials are wood, which is made of certain processing. The crystallization area is about 30%-40%. Such a high crystal area makes the infiltration of fuel not particularly good. Therefore, it is difficult to achieve darkness. It is necessary to use some special dyeing methods and fuels. Because of the lower polymerization, the strength of the fiber is not as good as the nylon. Myeing nylon fiber is a polymer material connected by dihamine amino acid or propyide and organic dilate through amine. It has high strength, abrasion resistance, durability, and has great elasticity. Commonly used are the nylon 66 and nylon 66. The disadvantage of the nylon 66 is that yellowing will appear at 66 degrees, and it will be viscous and softened at 230 degrees at high temperature. It will completely melt at 250 degrees at high temperature. The disadvantage of nylon at 6 degrees is to soften at 180 degrees and completely melt at 215 degrees. 2, adhesive The adhesives selected for velvet implants are divided into self -linked adhesives and diplomatic combined binders. (1) Self-linked adhesive is a group containing the molecular chain from cross-linking the cross-linking of the molecular chain. It also has a hydroxyditinicide (CH2 = CH-SONHCH2OH) or methyl acrocylite (CH2 = C-COOOCH2-CH-CH2) that can participate in the concentration (CH2 = CH-SONHCH2OH) or methyl acrocylite. Essence At present, these two adhesives are applied to velvet, and the effective placement time for self -integrated adhesives is relatively long. If a small amount of crossliers are used, the depth of the cross -linking is more suitable for improving velvet jurisdiction. Spend. Diplomat adhesives must be added with some cross -linked agents and catalysts when used, and they should be used immediately after the modulation, otherwise the crosslinker will be affected at room temperature. The choice of velvet adhesive (1) It is easy to operate, green and environmentally friendly, and harmless to people. (2) Moderate viscosity. It is suitable for the round net scraping. It will not block the net and chemically stable. (3) Wash with water resistance, composite the accuracy indicators of various cloths. (4) Because the adhesive has a large bonding force on the billet and fluff, it feels good. 3, dyeing fluff The fluff chunles must first meet the alignment color light, and the color is not complicated during the roasting process after the ampulse. After the velvet, if the printing is performed, then the dyed velvet should be able to withstand the treatment of each process of the entire printing process. If the dyeing printing is made, the dye in the dyed velvet must be impatient. Selection is very important, otherwise it will cause different hair extraction. The selection requirements for dyeing dyes (1) Various color targeting indicators of dyes should compound customer requirements. (2) In the extraction printing, dye dyes must be impatient to resist, and the whiteness is better. (3) The compatibility of color -fighting dyes is better, and there must be similar upper dye curves.

The velvet The woven fluff on the cloth with a specific process to increase the thickness and gorgeousness of the cloth. (It is a way of making) Pure wool planting velvet, which represents the raw material is pure wool, the manufacturing process is implanted It you can first understand the popularity of the following brands when you buy it, ask the details, and then ask the details, and then ask for details. Then Pay attention to the production date, whether the manufacturer’s information is complete
The has strong three -dimensional sense, bright colors, soft feel, luxurious and noble Do not take off the velvet, friction resistance, and flat.
In different demeanor products, choose the appropriate velvet method, generally divided into three types:
1 The velvet water line fluffy: this velvet flow line can be achieved From the upper glue, velvet, drying, and floating velvet, it is fully automatically completed, such as: velvet, leather, paper, non -woven, PVC, plastic film, sponge, various crafts, toys, cars, cars, cars, cars, cars, cars Plastic parts, storage boxes, automotive sealing strips, trim, plastic boxes, cardboard, calendar, couplet, New Year’s paintings, packaging gift boxes.
2 box -type velvet: According to the size and shape of the velvet products, the flocking box is placed in the box, and the power supply is connected. Veltic products are sent into the box from one end of the feldler. After three to five seconds, it will be removed from the other end of the box after the velvet, and it is the finished product.
3 nozzle type velvet: connect the power supply, and the tens of thousands of volt electrical electrostatic generated by the velvet machine is output into the workman’s nozzle. The surface is sprayed with a adhesive, the moving head is close to the velvet object, and the fluff is rising from the sprinkler to the surface of the velvet object under the action of the high -voltage electric field, and is placed vertically on the surface of an object with a adhesive.
The application example of velvet process:
The surface of various product substrates can be implanted, and it is not limited by the shape and size of the plant body. Such as: paper, cloth, non -woven fabric, artificial leather, plastic, glass, metal, rubber, wood plate, sponge, gypsum board, artificial board, plastic film, foam, ceramic, resin, etc.
The velvet characteristics: strong three -dimensional sense, bright colors, soft feel, luxurious and noble, gorgeous and warm, realistic image, non -toxic and tasteless, insulation moisture prevention, no fluff, friction resistance, flat without gap.
