Water absorption capacity: The cotton webbing of the webbing factory has a strong water absorption capacity. Under normal circumstances, the webbing can absorb nutrients from the surrounding air, and its water content is 8-10%, so it touches the human skin and makes people feel pure cotton soft and not stiff. If the relative humidity of the webbing air increases and the surrounding temperature is high, the water content in the webbing will evaporate completely, so that the webbing maintains a water-treated state, making people feel comfortable.
Heat resistance: pure cotton webbing has good heat resistance. When the temperature is above 110℃, it will only cause the water on the webbing to be consumed, and will not damage the synthetic fiber. Therefore, the pure cotton Guangdong webbing wholesale price webbing at room temperature, use, and cleaning the paper mill will not affect the webbing, thereby improving the washable and durable dyeing properties of the pure cotton webbing.
Alkali resistance: Cotton webbing has great resistance to alkali. In alkaline solution, the cotton webbing does not show any damage. This function is beneficial for cleaning environmental pollution and disinfecting stains after use. At the same time, pure cotton webbing can also be colored, digitally printed and processed by various processes to produce more improved varieties of webbing.
Combustion performance of ribbon materials
Polyester fabric ribbon: melts and burns when near flame, drips and bubbles out, but does not continue to burn directly, tastes like bamboo shoots, hard, round, light, brown to dark gray, beaded
Polyester fabric ribbon: melts and burns when near flame, drips and bubbles and can continue to burn, very few have weak smoke, clear sweet smell, hard round, black or light brown
1. Flax fiber and flax fiber
Both flax and linen fibers burn immediately when approaching flames, burn quickly, and emit yellow flames and blue smoke. The difference between the two in the smell and the ash after burning is that cotton smells like paper, while hemp smells like grass ash; after burning, cotton has a small amount of powdery ash, which is black or dark gray, while hemp produces a small amount of gray-white powdery ash.
2. Nylon and polyester fabrics
Nylon is also known as acetate fiber. It quickly curls up and melts into a milky white sticky substance when it is close to the flame. It melts and drips and bubbles in the flame. There is no flame when it burns. It is difficult to burn again without the flame. It emits the smell of bamboo shoots. After cooling, the light brown molten material is not easy to crush. Polyester fabric is also known as nylon fabric. It is easy to ignite. It melts and shrinks when it is close to the flame. When it burns, it melts and emits black smoke. It has a yellow flame and emits a fragrant smell. The remaining ash after burning is a dark brown lump, which can be ground into powder.
Three ways to identify the quality of the ribbon
Color difference inspection: This can be observed with the naked eye, looking at the color of the flowers, the texture, the curling and the edges of the needles. It should not be messy, but should be a relatively simple tone.
Burrs: There are usually some burrs on the yarn, which can be observed with the naked eye. There should be no serious yarn balls and burrs on the front and back of the ribbon and the seams.
Needle falling: This can be observed with the naked eye, and the webbing should not have needle falling.
Matters needing attention in continuous dyeing of ribbons

1. Factors of ribbon blanks: First of all, we should pay attention to whether the yarn used in the ribbon blanks is from the same batch, because the "oil" contained in different batches of yarn is different. If it is blended, it will become a factor of the color in the dyeing process; secondly, whether the blank has been pre-treated. The dyeing effect of the refined blank is very good, because the "oil" on the yarn is removed after treatment, and the dye can be directly in contact with the fiber for dyeing without protection.
