Polyester Color Yarns factory

The price of down on the Polyester Color Yarns factory is as high as tens of thousands and as low as tens of thousands. The three-layer structure will have an effect on the warming effect of the down jacket. Down is a kind of fluff that grows on the abdomen of geese and ducks, and becomes a feather called flakes.

Floodiness is a key indicator of down quality. A piece of clothing filled with 80 grams of fluffy down is better than 100 grams of fluffy down. Feather with a large amount of down and feather content will easily mislead the inspection during the detection process, which will increase the content of down and down.

Find gauze summary The current domestic down market price is very chaotic, there are all kinds of prices, even under the same national standard, there are different prices, and some are still very different. According to the small article on Gauze, because down is a kind of animal protein fiber, ten thousand triangles of tiny pores are densely packed on the down ball fiber, which can contract and expand with the change of temperature, produce a temperature adjustment function, and can absorb the body's flowing fluid. For example, the minimum standard 450 degree fluffy 90 duck down is better than silk and cotton, so the down is simply used as a thermal insulation material.

Research shows that the warmth retention does not always increase with the increase of the velvet content. The bulkiness test method is accurate only when it is checked by steam reduction method. The test methods and assessment indicators adopted in the GB / T 14272-2011 standard are difficult to check the quality of down. This makes goose down better warm than duck down. The higher the bulkiness, the better the quality of the down. The results showed that goose down is called duck down down with a large flower, small nucleus, long and thick velvet branches, and small and densely distributed velvet branches. Today, we mainly analyze the impact of down on the warming effect of down jackets to analyze why there is such a huge gap

 The rotation speed of the cotton swab should also be controlled. This requires real-time replacement of the tension gear. The friction coefficient of the false twister will affect the hairiness of the finished yarn. The roving weight unevenness is mainly controlled 1.As the last process of the pre-spinning, roving is not only an important factor that affects the spun yarn, but also the sliver, spectrum, and hairiness. The sliver cans should be placed regularly to avoid them.

The routine maintenance of mechanical parts and bobbins should be strengthened. 2. Large deviations will also cause serious quality problems such as uneven spun yarn weight and strong CV.. For example, the sliver cans for internal yarn placement are placed close to the machine, and the sliver cans for external yarn placement are placed far away from the machine. Rolling waves are sometimes found in pop charts. It is necessary to reasonably select the false twister for the front and back rows of the roving to reduce the difference in tension between the front and back rows of roving. 5.

The daily inspection and maintenance of carding and drawing equipment and the quality control of the laboratory.Due to the difference in the diameter of the bobbin and the wear of the bobbin hole diameter or bottom, the poor fit of the spindle groove and the pin of the spindle, the improper pressing of the palm or the position of the palm, and the number of palm pressing circles,

the number of spindles Varying heights or uneven spindle operation caused by other reasons will cause differences between the spindles of the same row of roving elongation laws, affecting the roving draw. In addition, the tension of the roving also changes with the Polyester Color Yarns Suppliers temperature and humidity of the workshop. 4, the placement of sliver cans. Causes uneven weight distribution inside and outside. 6. 3
