How to distinguish nylon yarn from acrylic yarn?

It must be a professional person, so he can distinguish between this nylon yarn and Qinglong County, but I know that the feeling of being away from the Longsha thread is a bit like cotton and linen.

First, the use of the two is different:

1. The use of nylon yarn: this kind of product has a wide range of uses, and it is a good material to replace steel, iron, copper and other metals with plastic, and it is an important engineering plastic; Cast nylon is widely used as a substitute for wear-resistant parts of machinery and equipment, and copper and alloy are used as wear-resistant parts for equipment. It is suitable for making wear-resistant parts, transmission structural parts, household appliance parts, and automobile manufacturing parts;

Screw rod prevents mechanical parts, chemical machinery parts, chemical equipment. Such as turbines, gears, bearings, impellers, cranks, instrument panels, drive shafts, valves, blades, screw rods, high-pressure washers, screws, nuts, sealing rings, shuttles, sleeves, sleeve connectors, etc.

2. The use of polypropylene yarn (also known as PP yarn): the webbing and rope woven with PP yarn polypropylene yarn can be used for all kinds of luggage belts, travel bags, backpacks, shoelaces, mobile phone slings and other noisy holes.

Second, the characteristics of the two are different:

1. The characteristics of nylon yarn: the abrasion resistance is higher than that of all other fibers, 10 times higher than the abrasion resistance of cotton, and 20 times higher than that of wool. When stretched to 3-6%, the elastic recovery rate can reach 100%; It can withstand tens of thousands of twists and turns, and it will not break if it is sensitized.

2. Characteristics of polypropylene yarn: because polyamide has non-toxic, light weight, excellent mechanical strength, grinding resistance and good corrosion resistance.

Third, the overview of the two is different:

1. Overview of nylon yarn: dragon is developed by the outstanding American scientist Carothers (Carothers) and a scientific research team under his leadership, and is the first synthetic fiber in the world, nylon is a statement of polyamide fiber (nylon). The emergence of nylon has changed the face of textiles, and its synthesis is a major breakthrough in the synthetic fiber industry, and it is also a very important milestone in polymer chemistry.

2. Overview of polypropylene yarn: PP yarn, polypropylene yarn is also called polypropylene yarn, PP yarn polypropylene yarn and polypropylene yarn polypropylene yarn is mainly used for webbing and rope.

1. Combustion method: nylon (commonly known as nylon) near the flame is quickly curled and melted into a white gelatinous form, which is melted and dripping in the flame and produces a small gas bubble, there is almost no flame when burning, it is blue, it will stop burning and self-extinguish when it is separated from the flame, and it emits an amino or celery flavor, and it is a hard and black bead-like melt after cooling and the fingers are not easy to grind. Polyester near the flame that is melted, will melt in the flame, there will be a yellow flame in the burning, the color of the flame edge is blue, there will be black smoke, it will burn intermittently out of the flame, it will also self-extinguish, emitting an aromatic smell, and the ashes will be black-brown hard lumps after burning, which can be twisted with fingers.

PP webbing (polypropylene webbing) close to the flame that is melted and retracted, burning in the flame will melt, there will be a flame of fire, the upper end of the flame is yellow, the lower end is blue, from the ** will continue to burn, will emit a paraffin smell, after burning the ash is light yellow-brown particles, with fingers can be twisted. 2. Feel: Nylon feels comfortable, smooth and soft, loosens after pinching it by hand, has creases, will recover slowly, scrape with fingernails, and there are no obvious scratches.

Polyester feels slightly rough, there are wrinkles after pinching and loosening by hand, there are still slight creases after flattening, and there are obvious scratches after scraping with fingernails. The feel of PP webbing is rough compared to nylon and polyester, the color of the webbing is relatively dull, and the yarn is relatively coarse. 3. Buoyancy:

Cut the yarn a little bit, twist the yarn into a ball, put it in the water, and after the water is soaked, the PP polypropylene that floats on the water surface is PP, and the nylon or polyester that sinks down. Fourth, dyeing: nylon webbing is the first ribbon and then dyed, after cutting the yarn due to uneven dyeing and white.

Summary. Hello, polyester is one of the most common man-made fiber yarns, which is similar to polyester.

Hello, polyester is one of the most common man-made fiber yarns, which is similar to polyester.

In addition, it is agitated and transported, acrylic yarn. Acrylic yarn has a great similarity with parallel polyester yarn, but acrylic yarn is more wear-resistant, more resistant to purple beams, better water resistance, more heat-resistant, and more resistant to chemical corrosion than polyester yarn.

Polyester yarns are the most similar to polyester, and they both belong to the polyester group of fibers. Polyester yarn and polyester both have good lightfastness, washability and wearability resistance, they are polymerized from polyester diester resin, suitable for making summer clothes, because they both have strong heat resistance, they can also be used to produce improved fiber clothing for spring burning, such as fire uniforms, work clothes and fitness clothes. In addition, they also have good adaptability of the Liangsen people, can adapt to different kinds of detergents and dyes, can be washed at low temperatures, and are suitable for making clothing and home textiles of various colors and samples.
