Benefits of technology

This patented technology allows for testing both qualitative and quantitatively how well it prevents fire hazards caused by flames or gases from burning fabrics made with materials like Polyethylene Terephthalate (PET). It also compares different types of fibers used together without causing any harmful side reactions that could affect their properties.

Problems solved by technology

This patents discusses how important factors affect the flamproofness/combibility of polyesters during their use in garment applications such as clothing, upholstery products, furniture cushions, automobile seat covers, etc., due to their ability to resist flames while maintaining flexibility at room temperatures. However, these technical effects make polyester surfaces vulnerable towards flaming attacks, especially those involving small particles called fine powders. Additionally, they often come off easily because of friction between themselves and objects placed nearby, causing harmful impacts like scaldings. Therefore, improving the flarnhold property of polyurethane composites requires developing better flame protection than existing ones.

Abstract

The invention relates to a method for preparing a high-performance flame-retardant terylene interior textile, which comprises the following steps: (1) coating slurry is prepared, and comprises the following compositions with the volume content: 50 to 70 percent of waterborne polyurethane dispersion liquid, 25 to 40 percent of a flame retardant, 2 to 3 percent of SiO2 synergistic agent, and 3 to 8 percent of thickening agent; and (2) a terylene fabric is coated, the sizing amount is between 160 and 240g/m<2>, and the baking is performed for 2 to 5min at a temperature of between 150 and 180 DEG C. The combustion performance of the textile obtained by the method reaches the national level B1, and the terylene fabric basically has no fused drops; smoke density and smoke toxicity tests reach grade F3 in French NF F16-101-1998 standard; and the smoke density tests meet the requirement of Boeing BSS7238 standard, and the smoke toxicity tests meet the requirement of Boeing BSS7239 standard.
