Embodiment

[0034] The polyester fabric is printed and laminated to a protective film. Test fabrics for gloss, surface roughness, shine and durability. These examples are for illustrative purposes only and are not intended to limit the scope of the appended claims.

[0035] Table 1 - Research Materials

[0036]

[0037] testing method

[0038] relative light reflection coefficient

[0039] Relative light reflectance is measured according to ASTM D523-14 using a BYK Gardiner Micro TRI Glossmeter; values ​​are measured at 60°. All samples were placed on ten sheets of white paper for normalization which may depend on the reflections returned from most surfaces. The gloss of the ready-to-use adhesive-backed protective film still on its original liner, which was placed on ten sheets of white paper for normalization may depend on the reflection returned from most of the surface. The term "percent gloss" is defined herein as the ratio of the measured gloss after lamination minus th...

Embodiment E1 and E2

[0079] Example E1 was prepared in a similar manner to Comparative Example C14, except that the protective film was Film 3 . Properties are summarized in Table 5. Example E1 shows a large reduction in gloss and a large increase in both surface roughness and essentially no sparkle relative to Comparative Example C11. The two-dimensional period of the embossed pattern on the topmost surface of the laminate construction resembles a two-dimensional sine wave with the same period as the underlying fabric and with an amplitude that approximates the peak-to-valley surface roughness. The Rz of Example E1 is more than double the nominal thickness of about 75 microns of the ready-to-use Film 3, which means that the Film 3 deforms plastically during lamination.

[0080] Example E2 was prepared in a manner similar to Example 1 except that the protective film was Film 4 . Glitter was measured to be roughly zero, in addition to a reduction in gloss and an increase in surface roughness, mea...

Embodiment E3 to E6

[0085] The purpose of Examples E3 to E6 was to explore the width of the lamination process window.

[0086] Unprinted sample FAB1 was laminated to film 5 using Orca I. The lamination pressure and temperature of the heated rolls were varied as described in Table 6. Record gloss and surface roughness.

[0087] Table 6

[0088]

[0089] accelerated aging

[0090] To determine the long-term stability of outdoor printed graphics, tensile strength was evaluated after accelerated aging. A material that retains at least about 50% of its original tensile strength after accelerated aging would be defined as outdoor durable.

[0091] Comparative Examples C1 and C2 and Examples El and E4 were aged and tensile strength was measured before and after accelerated aging. Tensile strength is reported in Table 7.

[0092] Table 7

[0093]

[0094] Comparative Examples C1 and C2 show that FAB 1 and FAB 2 do not meet the outdoor durability criteria.

[0095] Example E1 meets th...

Abstract

The invention provides a fabric with a laminated adhesive-backed protective layer. The adhesive-backed protective layer has a matte finish that is low gloss and may approximate the fabric itself

Description

Background technique [0001] The rapid growth of digitally printable fabrics has recently occurred due to the many perceived advantages of fabrics over other forms of printable media, such as lighter weight (and thus lower shipping costs and lighter frame equipment), and the ability to be used with Compatible with many digital printing technologies. In fact, even a casual look at most trade shows today will reveal an almost complete shift away from hard walls and other heavier and more expensive graphic media to printed fabrics. There are currently many printable fabric materials available. Printable fabrics for interior applications are widely distributed. As the market grows, the range of printable fabrics for outdoor applications is increasing. [0002] Most of the printable fabrics currently available are intended for interior applications and are used with dye sublimation printing techniques. Due to the temperature requirements for dye sublimation, most printable fabri...
