Seeing, touching, burning, identification of the three major methods you still will not use?

In front of various fabrics, are you still struggling to identify them? Are they torn whether they are "real" or not? If so, then this article today you must read, extremely practical.

We identify textile fabrics, there are three major methods: see, touch, burn.

Look at the series + touch the series

Seeing and touching usually do not separate, so we put together to say. So what to see and what to touch? Usually we look at the appearance form, color, luster, etc. of all kinds of fibers; touch the softness, thickness, elasticity, handfeel, etc. of all kinds of fibers. This method can quickly identify the following types of textile fabrics.

Colored cotton & dyed cotton

Color cotton is due to genetic variation and the color, currently stable only brown, green two colors, and the color is thicker, not bright. We can look at the color of its fiber cross-section - the color gradually fades from the center of the section to the edge.

Dyed cotton is chemically produced pigments on the fiber, so the entire textile has a uniform sense of color. The color on its fiber cross-section is the opposite of colored cotton - the color is darkest at the edges and gradually fades to the center.

Ring Spinning & Airflow Spinning

Ring spinning is mechanical spinning, that is, twisting by the spindle and steel collar and wire ring, and drawing by the roller. So look at its spinning twist direction, the twist direction is Z twist, with S twist to retreat the twist, the fiber can be separated.

Airflow spinning is a new textile technology and its yarn is generally coarser. Because the airflow yarn is formed by airflow gyration to form vortex, so the fibers on the surface of the yarn are entangled with each other, no matter it is retwisted with Z twist or S twist, the fibers can not be separated. Moreover, the yarn is fluffier, more wear-resistant, and more vibrantly dyed.


Combed yarn & compact spinning yarn

Combed yarn is a yarn spun by combing process. As the yarn count of combed yarn is higher, we can use this feature to shine the cotton with light and see through, the combed yarn is tighter so you can't see the hand shadow after transmitting the light. As for the feel is soft and delicate.

Closely spun yarn has few cotton knots, and the yarn is evenly dried, and the fabric is very smooth. We can also look at the demolition of the yarn, closely spun yarn of the whole yarn feathers are few, the surface is more polished, the whole cloth feel thinner than combed cotton.

Cotton bamboo yarn & linen yarn

The thickness of the bamboo joints, the spacing of the bamboo joints, the length of the bamboo joints, and the yarn count of the bottom yarn of cotton bamboo joints are all pre-designed, so there are certain rules.

Linen spun yarn has poor length regularity of hemp fibers and different lengths, so the spun yarn has a serious uneven stem, the longitudinal direction of the yarn count shows irregular bamboo joints of different thicknesses, and the spacing of bamboo joints is not regular.

Burning series

Because there are many types of fibers, it is impossible for most people to identify them accurately by looking + touching. Therefore, we need to use tools to identify them by visual phenomenon. Here I have listed the following.

# cotton fiber
Cotton fiber is flammable, yellow flame, blue smoke, burning paper odor, continue to burn away from the fire, burn to maintain the original line, fine soft dark gray, hand touch that scattered.

# wool fiber
Wool fiber curled in fire, smoke, with burning hair odor, away from the fire that is extinguished. Its ash curled, shiny, and black swollen fragile particles.

# Hemp fiber
Hemp fiber is flammable, yellow or blue flame, with burning paper odor, ash is white or light gray.

# Viscose fiber
Viscose fibers burn quickly, with a burning paper odor, ash less (similar to cotton and hemp fibers).

# Silk fiber
Silk fibers burn slowly, first curled into a ball and then flame, with burning hair odor, more ash, a small black-brown ball, away from the fire to stop burning.

# nylon fiber
Nylon-fiber quickly curl up when exposed to fire, melt while slowly burning, no flame, celery or fire paint smell, melt after a white gel, while hot can be pulled into silk.

#Polyester fiber
Polyester fibers on fire first curl and then burn, the flame is yellow-white, aromatic odor, not extended combustion, the ash is black hard, can be crushed by hand.

# Acrylic fiber
Acrylic fiber burning slowly, shrinkage melt, flame flash, white, very bright, with fishy smell, ash is brittle small black hard lumps.

# Vylon fiber
Vylon fiber burning also shrinkage, molten, with thick black smoke, the flame from small to large, the ash is black small pieces, hand crushed that is broken.

# chlorine fiber
Chlorine fiber softened by heat, first molten and then burned, the fire is extinguished, the ash is black hard lumps.

# Polypropylene fiber
Polypropylene fiber shrinkage, melting, burning, black smoke and burning wax odor, can be extended combustion, and gel dripping down, cold was hard, hand pressure can be broken.
