How to distinguish between nylon and polyester corduroy and 100% cotton corduroy. What is the difference between nylon and polyester corduroy and 100% cotton corduroy?
How to distinguish between nylon and polyester corduroy and cotton corduroy? The difference between nylon-polyester corduroy and cotton corduroy is that traditional corduroy is mainly made of cotton yarn. However, with the rise and development of differentiated fibers, polyester-nylon ultra-fine composite yarn has been widely used in corduroy fabrics, making the wick Some properties of corduroy have been improved, giving corduroy a new look. Jinpoly corduroy and cotton corduroy each have their own characteristics, and they are evenly matched in terms of application and sales! But what is the difference between the two? How can you quickly distinguish between nylon and polyester corduroy when you get a piece of corduroy fabric sample? Or cotton corduroy?
The following is a brief introduction on how to distinguish:
First of all: taking advantage of the difference in ingredients, cotton corduroy is 100% cotton, while nylon-polyester corduroy is polyester-nylon composite yarn Woven, the composition is generally 90% polyester, 10% nylon. In this way, we can use the combustion identification method to determine whether the fiber of the fabric is cotton or polyester and we can distinguish it!
Combustion identification is a simple identification method. Since each fiber has a different chemical composition, it will show different phenomena when burned. This can be used to identify the fiber raw materials in the fabric! Pull out several yarns from the fabric, hold them close to the flame, and carefully observe the changes that occur to the fibers as they burn.
1. Is there shrinkage and melting when approaching the flame
2. The color of the flame and the state of the fiber during burning
3. When leaving the flame Whether the fiber continues to burn and the smell emitted by the fiber
4. The color, shape and hardness of the burned ashes!
Cotton yarn will not melt or shrink when it is close to the flame!
Cotton yarn burns very transparently, with a smell of burning paper, and there is almost no ashes. The ashes are very light and fine and disappear after a twist!
When polyester touches the flame, it immediately melts, shrinks, and emits black smoke!
When polyester burns, the ashes form black balls!
The above is by splitting the yarn and burning it. It can be seen that there is a big difference between the burning of polyester corduroy and cotton corduroy, and they can be easily distinguished!
Secondly, based on the difference in composition, the corduroy of nylon-polyester corduroy and cotton corduroy have obvious differences in appearance, color, feel and other aspects. Differences, we can distinguish the two through these differences!
1. Jin-polyester corduroy is brighter and brighter, while cotton corduroy is dryer and matte
2. Jin-polyester corduroy should be plump, round and fluffy full! The velvet surface of cotton corduroy is relatively flat.
3. Polyester-nylon corduroy uses polyester-nylon composite yarn, and polyester-nylon composite yarn is ultra-fine fiber. It has many fibers, small fineness, and reduced bending stiffness, which improves the properties of corduroy. The feel of nylon-polyester corduroy is much softer than that of 100% cotton corduroy. 100% cotton corduroy is relatively hard if not washed! So you can roughly judge by the feel!
4. The surface of nylon and polyester corduroy will have severe frost blooms (partial areas are white, and the polyester and nylon are reflective and shiny), while cotton corduroy has almost no frost bloom effect.
5. The polyester-nylon composite yarn used in nylon-polyester corduroy is filament, while cotton fiber is short fiber. The tear strength of polyester is much greater than that of cotton fiber, so a piece of yarn pulled out If it breaks easily, it should be made of cotton!
6. Through the back, the back is made of nylon and polyester and has a rougher feel, while the cotton one is smoother and softer in contact with the skin. This is because polyester is hydrophobic and cotton is hydrophilic. Cotton fiber has better hygroscopicity, so it will be more skin-friendly when in contact with the skin!
As for how to distinguish nylon-polyester corduroy from cotton corduroy, it is relatively simple, fast and accurate to use the fiber burning identification method. To understand the difference between the two, we can combine several characteristics Come to judge and prove!
