Fluorescent Fabric is a bright, vivid fabric that is designed to stand out and make a bold statement.
The material is a combination of both polyester and cotton fibers, which creates a fabric that is soft, comfortable, and durable. The fabric is also highly resistant to wrinkles and shrinkage. Neon and Fluorescent Fabric is ideal for a variety of bold fashion projects, such as stage costumes or party dresses that are designed to stand out from the crowd.
A fluorescent coating is dipped onto the fabric to make it appear bright and radiant. The coating is made of a mixture of a fluorescent dye, a resin component, and a binder to help it stick to the fibers. The resin helps to hold the fabric together and prevents it from tearing or fraying. The color of the coating can be customized to meet the needs and preferences of the customer.
The dye in the coating absorbs light energy from the surrounding environment and emits it at a longer wavelength. The emitted wavelength is usually in the red or green spectrum. The material can be used to mark objects and is very useful for safety equipment, such as reflective vests and jackets, to increase the visibility of people in low-light conditions.
There is a wide variety of fabrics that use fluorescent materials for increased visibility, including shirts and pants, skirts and dresses, and even footwear. Many people choose to wear this type of clothing during outdoor activities such as hiking, camping, or fishing. Others are required to wear this type of clothing for safety reasons, such as road workers or police officers.
Optical brighteners are chemicals that increase the appearance of white fabric and paper by emitting more visible light than the amount that shines on them. The blue light emitted by optical brighteners compensates for the yellowish tone of the fabric and makes it appear much whiter. Optical brighteners are commonly used in laundry detergents, high brightness paper, and cosmetics.
The present study compares four different retroreflective materials and fluorescent fabrics in order to develop safety clothing for road traffic workers, police personnel, and vulnerable pedestrians that complies with ISO standards regarding the material and design of warning clothing. The fluorescent fabrics selected for comparative analysis include a PET 71%/Cotton 23%/PU 6% fabric currently used in public road cleaner uniforms in Korea (S1), an ISO-compliant Japan-made PET 65%/Cotton 35% + conductive fabric for adults and children (S2), a rectangular patterned sample manufactured by a Korean 'R' company (R2), and a random plain trial sample obtained from a special fabric marketplace in Korea (R3). The physical properties of the samples were evaluated according to seven evaluation criteria and ISO 20471. The surface of the fluorescent and reflective fabrics was observed using a scanning electron microscope at 200x magnification, while their internal structure was examined with a transmission spectrophotometer (Varian Cary 50 Solarscreen) and a CIE whiteness meter (Datacolor SF 600 PLUS-CT). The air permeability, fabric weigth, relative intensity of fluorescence, and yellowness index of the fluorescent fabrics were measured.
