What is the finish of flame retardant fabric?

1. Flatness: aatcc124, washing test and shrinkage test, generally each customer is corresponding, the main washing temperature, washing times are different

2. Waterproof performance test: The general initial value and the measured results are tested? wash

Waterproof system test: spray method: AATCC22 and ISO4920 same

Drip method: See the diffusion of droplets, with direct water penetration into the surface of the cloth has good

3. Oil proof performance test: directly affect the oil drop 0.5MM size of the oil drop, 30 seconds after diffusion

4 formaldehyde content test: in general, the conventional finishing formaldehyde content is less than 20PPM, so the physical test is generally not tested.. Test formaldehyde content with resin finish only.. AATCC112 and JIS L1041 are two of the most used tests in the world. The reflective part of the reflective clothing manufacturer is made by using the principle of micro-rhomboidal refraction of the lattice and the regression reflection principle of glass microbeads with high refractive index through the advanced technology of post-focusing processing. It can reflect the distant direct light back to the luminous place, no matter in the day or night has good inverse reflection optical performance. In particular, at night, visibility is as high as it is during the day. The high-visibility reflective material makes it easier for night drivers to spot the wearer from a distance or in the presence of light or scattered light. The appearance of reflective materials smoothly solved the "see" and "be seen" this night driving problem. Reflective suit A reflective safety suit that can reduce traffic accidents at night. It is a safety suit that places reflective film on the surface of clothing and is used for road or road work at night. In the case of no interference at night, the effective distance of reflection and luminous is 500 meters, the safety suit is simple to manufacture, convenient to change the film, low cost, easy to promote, is an ideal night safety protective clothing.

Free formaldehyde: The formaldehyde free from propional content is soaked in water, and after a certain temperature, time and static treatment, it is hydrolyzed and dissolved. Reflective suit A reflective safety suit that can reduce traffic accidents at night. It is a safety suit that places reflective film on the surface of clothing and is used for road or road work at night. In the case of no interference at night, the effective distance of reflection and luminous is 500 meters, the safety suit is simple to manufacture, convenient to change the film, low cost, easy to promote, is an ideal night safety protective clothing.

Formaldehyde release: Measured by releasing exposure to a specified temperature, time, and static treatment after photographing the face cloth method, formaldehyde release in the air, then dissolved in water.

In general, the formaldehyde released in this case is higher than the free formaldehyde.

5.PH value: The normal use of fabric dissolved in water, determine the PH value of the water. Because the front channel is sometimes not clear about the mercerite base, adding acid is always tuned to the channel, however, excess can result in adding acid and a decrease in acid-base strength.
