Brief Analysis Of Coating And Laminated Textiles Technology

The coatings industry relies heavily on polymers and polymers, polymers, additives, footprints and other chemical necessities in the specialized chemical industry to produce products with certain quality standards and durability to meet the needs of specific customers.

Textile coating and laminating processes are similar to those in the film and paper industry. Polymer coatings or laminates on films and paper are laminated onto other materials. In fact, the boundaries between paper and some nonwovens are very blurred.

The nonwoven industry itself is probably the largest user of polymer resin adhesives.

The fabric coating also uses a number of polymers used in the coating industry, such as acrylates and polyurethane. In fact, some analysts now use it.

Industry has become a coating.

Similar to lacquer, the best results can be obtained by using several thin coatings instead of a thick coating in the process of coating.

The coating machine is more complex than the textile equipment, and its production and production speed are much higher in the process of membrane processing.

In coating and laminating process, paper and textile have higher production and production speed.

Generally, film and paper have better dimensional stability than fabric, but high production speed can cause other problems.

By comparing these related industries, we can learn knowledge and promote the development of the nature industry.

Other industries related to fabric coating include the rubber industry, the origin of coated fabrics and the rubber industry (there are still many rubber materials used for fabric coating), and fabrics and polymer composites belong to the field of high technology and high growth.

Fabric coating is also related to fabric printing. In fact, some ink coatings are adhesives which are defined by pigment printing. Some of them are polymers that are coated with coatings. The thickeners in pigment printing ink are similar to those used in fabric coatings.

It is difficult to distinguish between "full width" printing and light coating. The rotary screen printing machine can easily finish the coating.

Fabric coating and lamination involve the following disciplines: textile technology, chemistry and polymer chemistry.

。

The design, drawing and preparation of base cloth need to be used in textile technology. The base cloth determines the tear strength, tensile strength and coating suitability of the coated fabric.

Fabric must be properly prepared in advance to obtain immune polymer adhesion and soft handle and drape.

We can have knowledge and skills in polymer chemistry to decide which polymers to use, such as PVC, polyurethane, acrylic resin, and specify the coating formula.

The combination of coating compounds with chemical additives such as flame retardants, plassols and processing aids can produce special properties.

People can use chemical engineering and mechanical engineering knowledge to design the coating machine oven, which has the appropriate drying rate and easy to recover from smoke and solvent (or water) to function in order to produce products with specific technical properties on a large scale.

The treatment of materials, especially those coated (or laminated), is sometimes ignored, but it is extremely important.

This process often determines the profit margin of the product, because the use of fabrics that are oily, damaged or wrinkled will lead to a reduction in the quality of the products.

Automation and reliability control are used in many of the devices currently developed, thus reducing "artificial factors".

Information technology and computers play an important role in the work schedule. The use of equipment and the utilization of resources are optimized through better information, stock operations and more effective procurement.

With the further development of information technology and the popularization of computer applications, this trend will be strengthened.

Personnel management requires training and motivating technicians and staff, cultivating team spirit and maintaining a progressive culture.

This is the need for reform and the need to produce qualified products with the least inferior materials. It is best to use "zero" defect materials to ensure business success.

The challenge of commercialization and mass production of products is that the challenges facing R & D at the beginning of the laboratory are the same, perhaps larger, because technicians are generally inferior in quality to laboratory personnel.

Work has a certain degree of repetition, so throughout the process, we need to pay attention to every detail, especially in high speed production, because many defective fabrics have been produced before finding defects.

Regular maintenance of machines and meticulous cleaning are also necessary.

Environmental factors are becoming more and more important. The government and local authorities are committed to improving air quality by reducing the production of volatile organic compounds (VOCs) and other emissions.

Good air quality is beneficial not only to human health and safety, but also to global warming and climate change.

A number of restrictive measures have been introduced, mainly to prevent the discharge and use of chemical reagents with potential toxicity in the compounds used in the coating industry.

Reducing the amount of waste that needs to be disposed of by landfill and encouraging recycling of waste will also help the development of coating and laminating industries in the textile industry.

The recycling of coated fabrics is being re examined. This will eventually become an important factor in the suspension of materials.

Because many coated fabrics are two or more than two polymers, they are difficult to recycle at one time.

In view of this problem, the fabric coated with water-soluble coating with the same or similar polymer composition is more recycled. Therefore, Germany has developed a water-soluble polyester polymer as a coating material for polyester fabrics.

In addition to the modification of base cloth, polymer coatings are also used as organic chemicals or containers for special chemical reagents or pigments, for example, mixing suitable chemicals into polymer coatings and coating them on fabrics to produce items of high visibility or "fluorescent sunlight".

This approach is usually more flexible than the method of dyed fabric with high visibility dyes, because higher concentrations of pigment or fuel are easier to get into the coating agent, and it is difficult to directly dye the fabric.

Special chemical agents such as antibacterial agents or antistatic agents can be easily washed, erased or worn out by finishing the fabric.

But if these facts are mixed into polymer coating agents, they will be difficult to remove.

Other special reagents that are difficult to produce unique effects include photosensitizers that can glow in the dark, dyes that change with temperature, ultraviolet absorbers (anti skin cancer), "phase change materials" (cold time heat release, heat time refrigeration), deodorants, aromatics and flame retardants.

Microcapsules containing millions of small capsules of about 3~5um diameter can improve durability and enhance the efficiency of many chemical reagents mentioned above.

Capsules can be volatilized, washed or removed by textile chemicals or substances.
