Principles and Applications of Coated Textiles

THE use of coated textiles for protective clothing, shelters, covers, liquid containers, etc., dates back to antiquity. Historically, the earliest recorded use of a coated textile was by the natives of Central and South America, who applied latex to a fabric to render it waterproof. Other materials such as tar, rosin, and wax emulsions have been used over the years to prepare water-resistant fabrics. Due to their vastly superior properties, rubber and other polymeric materials have become the preferred coatings. Today, coated fabrics are essentially polymer-coated textiles. Advances in polymer and textile technologies have led to phenomenal growth in the application of coated fabrics for many diverse end uses. Coated fabrics find an important place among technical textiles and are one of the most important technological processes in modern industry.

Coated textiles are made impermeable to fluids by two processes, coating and laminating. Coating is the process of applying a viscous liquid (fluid) or formulated compound on a textile substrate. Lamination consists of bonding a preprepared polymer film or membrane with one or more textile substrates using adhesives, heat, or pressure. Fibrous materials are also used for reinforcing polymeric materials to form composites for use in tires, conveyor belts, hoses, etc. The scope of this book has been restricted to coated and laminated coated textiles and does not address polymer fiber composites.

Several methods of production are used to manufacture a wide range of coated textiles or laminated fabrics. Broadly, they are spread coating, dip coating, melt coating, and lamination. They not only differ in the processing equipment used, but also in the form of polymeric materials used. Thus, paste or solutions are required for spread coating; solutions are required for dip coating; and solid polymers such as powders, granules, and films are required for melt coating and lamination. The basic stages involved in these processes include feeding the textile material from rolls under tension to a coating or laminating zone, passing the coated textiles through an oven to volatilize the solvents and cure/gel the coating, cooling the fabric, and subsequently winding it up into rolls.

PVC Free Banner Printing

We offer printing onto PVC free banner material at widths up to 3.1 Metres and at almost any length which means that we can produce almost any sized custom made size on demand.

PVC free banners are printed using a UV digital process that provides a durable finish that is waterproof and highly resistant to fading too.

Unlike some other printing processes, UV digital printing involves the use of no harmful solvents (VOC’s) that are environmentally damaging.

Eco Friendly Banner Finishing

Printed banners are traditionally finished with a seam around the edge and eyelets so they can be hung using rope, bungee cords or other fastenings. With some pvc-free materials, this is not possible because the material is not suitable for heat welding. This is a disadvantage since a welded seam gives maximum strength for the hanging eyelets that are punched through it.

Fortunately our PVC Free banner can be heat welded in exactly the same way as the traditional PVC product so there is no compromise as to the strength of the eyelets.

We offer pvc free banners with eyelets positioned at intervals of approximately 1M around the edge for hanging or we can finish the banner with pockets at the top and the bottom if you would like to slide rods inside to hang it. If you don’t want the banner finished with eyelets or pole pockets, that’s no problem either.

Choice Of Material Grade

We have PVC free banners available in two material grades. Our economy material has a weight of 210g per sqM whereas our premium material is heavier at 300g per sqM.

Both products can be printed at the same photographic quality with no restriction on the amount of colour that can be used within the artwork.

We recommend our economy material for short term event use whereas our premium PVC free banner material is recommended for longer term use outdoors for up to 6 Months.

Of course the lifespan of any outdoor banner can be shorter or longer due to environmental conditions, prevailing weather and other factors.

Digital Printing Fabric Fact Sheet

WHAT IS DIGITAL PRINTING?

First, let’s look at conventional printing. Conventional screen printing requires the engraving of one screen per color in a design. So a design with 18 colors would require 18 screens. Additionally, 18 separate colors also need to be mixed and matched. With digital printing, there are no screens or colors to mix. Any image you can see on a computer can be reproduced on fabric in the same way as your desktop printer prints images on paper.

WHAT FABRICS CAN BE PRINTED?

Unlike other digital printing operations, our digital printing fabric solution is not limited in regards to any fabric content. We can print on cotton, polyester/cotton, rayon, silk, linen, nylon, wool, etc., as well as blends with a maximum width of 66”. There are however various reasons why any specific fabric may not perform well on our printer. Examples of things that can make a fabric unprintable include: water repellent finishes, softeners, hairy fabrics, extreme textures, sheer fabrics, warped selvages, long haired selvages, etc.

ARE THERE ANY DESIGN LIMITATIONS?

The more ink coverage a design has, the more likely the hand feel of a fabric may be affected. Designs with large solid flat backgrounds or other large flat areas, primarily in darker shades, may not print solidly. Some colors will print more pixelated than others.

WILL YOU PRINT ON MY FABRIC?

No. We are unable to control the quality of a customer’s fabric and to control potential fabric losses due to the performance of that fabric on our printer. For this reason, we will not be accepting a customer’s fabric for use on the printer.

WHAT KIND OF INKS ARE USED?

Our digital print solution uses a patented pigment ink technology that is water based and absolutely free of heavy metals, formaldehyde and Alkylphenol Ethoxylates (APE), making them non-hazardous, non-toxic and 100% biodegradable. Our inks adhere to the strictest human health and environmental standards and contain no animal by-products and are completely vegan friendly, meeting both the Oeko-Tex 100 and Global Organic Textile (GOTS) standards.

IS THE FABRIC WASHABLE AND COLOR FAST?

The printed inks are all washable and meet excellent color fast standards. The below results are, in general, readily achievable, however results may vary depending on the basecloth and how it was finished. We recommend: Machine wash cool or warm, delicate or gentle cycle, Tumble dry low, remove promptly. Best to iron the reverse side. Ultimately, it is buyer’s responsibility to order and test sample yardage to establish any performance standards that they require.

WHAT DO YOU NEED TO PRINT MY DESIGN? ARE THERE ANY DESIGN LIMITATIONS?

The image file can be any Photoshop (PSD), JPEG, or TIFF, file, with optimally 300 DPI. When designing continuous patterns they should be put into a repeat, however, unlike conventional printing, your repeat is not limited by the size of the print screen. You can also print panels and other engineer layouts.

WHAT ABOUT COLOR MATCHING?

Digital printing is more of an art than a science. The color effect seen on a computer screen is not exactly what will print out on the fabric. Though a vast number of colors can be achieved, there are some colors that go beyond the range of digital color, making exact color matching problematic. To help with managing color, you may wish to purchase a color guide printed on the fabric you will be using.

Benefits of Polymer Coatings for Improving Textile Performance

Coated textiles may be subject to a number of external pressures and abrasive elements during everyday use. For this reason, a number of coatings have been developed to reduce the wear of textile materials. Polymer coatings, in particular, offer enhanced protection on the surface of textile products while still allowing for water evaporation through the fabric—a process that is often hindered by other coating materials. Here are the 10 primary benefits of polymer textile coatings:

1. Abrasion Resistance

Abrasion resistance is measured by rubbing flat materials against the fabric in question to determine the rate at which the fabric erodes. Polymer coatings create a layer on top of the textile fabric to add increased resistance to abrasion. It is particularly useful for materials that experience a great deal of friction, such as personal protective equipment (PPE), power transmission belts, backpacks, footwear, and synthetic leather products.

2. Adhesive Qualities

Textile fabrics can be coated with polymers to increase their adhesion and tack to other surfaces or polymers. For this reason, rubber polymer coatings are ideal for use in high-performance vehicle tires, power transmission belts, and seals and gaskets.

3. Air-Holding Capabilities

Polymer-coated textiles can incorporate resistance benefits to stop items like air or water from passing through the material. This makes them particularly useful in products that need to be capable of holding air, this would include items such as SCUBA buoyancy compensators, life vests, airlift bladders, blood pressure cuffs, pressure infusor bags, aerostates, etc.

4. Antimicrobial Properties

Polymers such as chitosan—a naturally occurring biopolymer derived sea creatures—display measurable antibacterial activity, sometimes with a reduction of up to 99%. Since surfaces coated with these materials remain clean and virtually free of bacteria, they are particularly useful in medical textiles, such as bandages, blood pressure cuffs, braces and prosthetics.

5. Flame Resistance

Polymer coatings may be combined with flame-resistant agents to create highly flame-resistant materials, which make them important in the manufacture of protective clothing for firefighters, fabric used in vehicles and airplanes, thermal ablatives for rockets, and safety curtains and carpeting.

6. Durability

Polymer coatings make textiles more sturdy and corrosion-resistant, significantly extending the service life of finished products ranging from household goods like towels and sheets to outdoor camping equipment and outerwear.

7. Noise Abatement

Coated textiles in polymer blends possess sound reduction properties. When sound waves are directed toward the materials, they are absorbed due to its porous nature, thereby preventing the movement of sound. This can be particularly useful in soundproofing layers in automotive, aerospace, and industrial applications.

8. Thermal Resistance

Materials coated with polytetrafluoroethylene (PTFE) or perfluoroalkoxy alkane (PFA) blends are able to withstand temperatures of up to 500° F. Like flame-resistant coatings, these polymer-coated textiles are particularly useful for safety products, automotive and aerospace fabrics, and firefighting apparel.

9. Waterproofing

Polymer coatings provide an excellent means for waterproofing textiles. Their hydrophobic nature ensures that materials coated in certain polymer blends easily repel water and other liquids.

10. Weldability

Polymer coatings may need to be bonded through the use of adhesives, RF, ultrasonic or hot air weldable. These types of fabrics are ideal where a durable sealed seam is required and normally sewn seams create unwanted holes in the surface. These weldable coated textiles are ideal for items such as weatherproof outerwear, inflatable vests, rafts, medical devices, and recreational BC vests.

Three minutes, Understanding of Coated Textile

What are coated fabrics, coated textiles? What are the development and future trend of coated textiles? Only by understanding coated textiles can we better guide the future development of coated textiles.

What is coated textile? Coated textile is a material treated by special process (through the post-treatment technology of cloth, belt, pipe, felt and grid), which makes the textile surface form a uniform coating compound. The coated fabric is a kind of coated textile, which consists of two or more layers of material, at least one layer is fabric and the other layer is completely continuous polymer coating.

However, this explanation is professional and unfamiliar, the average person may not think of which of the life is coated textiles. When you are on the highway, you will see the big cloth mantle that covers the goods on the roaring van next to you, and you will cover your car with a raincoat like the clothes of the car on a rainy day. Including our own rain gear, as well as most of the breathable sneakers upper and so on, these are coated textiles. The main common coated textiles are: PVC coated fabric, PTFE coated fabrics, PU coated fabric, Teflon coated fabric, silicone-coated fabrics, vinyl coated fabrics and so on. Coated textiles are widely used: not only can make waterproof clothing, tents, shoes and socks, curtains and other daily necessities; but also can be used in transportation, navigation, various machine accessories, and other industrial fields.

How do you clean digital printed fabric?

Water Pigment print confers a long lifespan. As in any natural product, the print and digital printing fabric will mature and soften with minimal colour loss over time. The quality of the digital printing fabric base and wash care can play an important part in the longevity of your digital printing fabrics.

Digital printing fabrics should be prepared for printing( ‘PFP’ ), free of all impurities.

Softener should be removed before printing as the ink needs to adhere itself to the digital printing fabric fiber without any interference

For best results using eco water pigment printing:

  • Gentle hand wash using cold water ( For first wash keep item separate).
  • Avoid strong detergents, hard spinning, hot or industrial wash.
  • Drip dry – do not wring.
  • No excessive rubbing on print.
  • Iron on reverse.

Digital Printing Fabric Care Labels

Each digital printing fabric quality will have its own unique wash fast properties to pigment printing. Customers are liable for their own digital printing fabric tests prior to bulk manufacture. Labels with the necessary wash care instructions should accompany all digital printing fabric products.

Optional – digital printing fabric coatings & treatments

We have coatings that can improve wet or dry rub fastness and fixing agents for problematic digital printing fabrics . Our softening agent & water- repellents treatments may be applied to the digital printing fabric after printing if required.

What is coated textile used for?

The use of coated fabrics is common in industry, in transmission belts, conveyor belts or barrier materials.

Equally, in the field of health, coated fabrics are used as barrier materials, implants, incontinence products, hospital equipment and hygiene products.

Coated textiles are common in gloves, cut resistant materials, clothing for clean rooms, fire, bad weather or NBC protection clothing, high visibility clothing, etc.

They also have their applications in the sports (shoes, anoraks, etc.) and leisure sectors (haversacks, camping tents, sleeping bags, etc.)

The possible uses of coated textiles are constantly growing, especially the breathable and waterproofing textiles. With this increase, there is a notable variation in the materials employed. From two years ago a progressive decrease in PVC coating (except for truck canvas) and an increase of polyurethane coatings are noticed. On the other hand, an increase is foreseen in coated textiles being used in textile architecture (PES/PVC or glass/PTFE), airbags, reflectors or posters and publicity flags amongst others.
