Hello everyone, meet again!
I am a fabric.
The weather is gradually warm,
Recently, I will pick it up online.
Cotton four-piece home textile
It’s awkward …
I lost myself, I found …..
Water washing cotton? Cottage? Cotton? Long velvet cotton?
Emmm …. So cotton products can’t help but get confused
These are all cotton fabrics?
How to identify cotton fabrics?
What is the characteristics of cotton fabrics?
How to choose cotton fabrics?
What is the cotton 12868 and cotton 13070 in the market? With a lot of questions, today we evaluated the popular market.
Cotton 12868, cotton 13070 fabric.
Fabric Science Tips
The cotton fabric 12868 is an indicator of the density considerations. 12868, 128 * 68, indicating 128 square inch, 68 weft yarns. The quality of fabrics is density, which is usually speaking, the number of yarn, the finer, the finer, the higher the density, and relatively, the better firmness, the better the fabric quality. Therefore, under the premise of bed product quality, the most important thing is to look at the density, the better the density.
We took a small cotton fabric to ignite it, observe its combustion status and the gray surface of the burning.
Burning cotton fabric we finally discovered that the fabric when burning
Slowly burning past.
Flame orange yellow, blue smoke
. After leaving the flame, you can continue to burn. Burn paper
There is less ash, linear. The gray is fine, shallow gray, hand touch into powder
. This is also one of the most common methods for identifying cotton fabrics, and most people think that cotton is flammable, heat resistance should not be good, in fact, cotton fabric is only 110 ° C below 110 ° C, will only cause water to evaporate on the fabric, no Fibers will be injured.
We take 12868 cotton fabrics, 13070 cotton fabric sample, soak it in a small soda solution for 1 hour, observe the soaking process
Is there a faded, yellow, etc.
The situation occurred, and finally observed its patch and protocol. (
Small soda: The little soda is called heavy base, alkali, alkali, screwdriver, etc., named sodium bicarbonate, is a weak alkaline white powder
The evaluation results were observed in a basic solution in an alkaline solution, and the cotton fabric is not affected.
Strong resistance of alkali
Cotton fibers in alkaline solutions,
Fiber does not destroy
This performance is conducive to the washing, disinfection of the garment, and also facilitates dyeing, printing and various process processing of cotton textile.
We take the cotton fabric and the non-cotton fabric sample, which cover it on the hot water cup of 100 ° C, and the other empty cup is covered with a fabric, and the liquidation of the water vapor is collected in the cup wall. The situation, in a period of time, compare the moisture absorbing breathable performance of the two fabrics.
By testing is not difficult to find that the moisture absorbing breathable properties of these two fabrics are different. In general, cotton fibers have better hygroscopicity. In normal cases, the fibers can absorb moisture in the atmosphere around them, and their water content is 8-10%, so it contacts people’s skin, making people feel soft and Not stiff.
Identify cotton fabric, first we have to touch it with your hand, feel the feel of the cloth, in general, did not add any fibers or add a small amount of chemical fiber, touch it, but not smooth, so buy cloth Try a try before you have before.
The surface of the cotton cloth is not bright, you can take a look at the light, there is no reflective phenomenon. In addition, it can also be clenched with the hand, and after loosening, it is observed that there is a lot of pleats on the surface of the cloth, and the cotton cloth is easy to wrinkle, so this method can also be tried.
The fibers of the cotton cloth are relatively rough. After the fabric is usually good, they cut a small mouth on the fabric, tearing the fabric, when torn openings, you have to look at and listen to the sound, look, how much, cotton cloth It is usually not so torn, and the sound heard is not as smooth as many chemical fibers.
The fabric of many fibers is prone to static, and the cotton fabric is machined from natural materials, and there is basically no static phenomenon.
Touch, two, three listening, four use
Do you remember?
