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

Card clothing can be used loosely and replaced freely.4 tex, and the carding table produces 24 kg / h, the use cycle of imported first-line brand cylinder clothing is 3 years, the use of imported ordinary brands is 2 years, and the domestic first-line brand clothing is used. Ensuring the smoothness of the suction system of the card is also conducive to ensuring the quality of the card sliver. 3) There are no complete management regulations for card clothing and the use of ledger. The key to ensure the smoothness of the air suction system of the carding machine is firstly that the amount of dust filtering air is appropriate, and the second is that the operating personnel timely check and eliminate it.

It is recommended to establish a card clothing replacement account, and continuously carry out optimization and selection tests of card clothing models, and choose a brand and model that are suitable for the company and have high cost performance. For accidentally damaged clothing, the cause must be found to prevent secondary damage after the machine is installed.5 years, which can meet the quality requirements of USTER 2013 bulletin.. For example, when using 100% cotton long-staple cotton combed 7.It is recommended to set the life cycle of the card clothing according to the actual output and the quality of the card clothing, and to observe the state of the card clothing and the carding quality at any time to ensure the card clothing use time and the quality of the finished product. When the clothing changes due to unexpected reasons, strict evaluation must be performed. 2)

The card clothing is injured and sick while running. If the variety changes frequently and the raw material changes greatly, it is recommended to choose a universal card clothing, taking into account the quality of the yarn between different raw materials. The cycle is 1. According to the AFIS test, when the suction pipe of the Polyester DTY Yarns card is blocked, the neps will increase more than twice

 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

There are many harvesting methods during cotton harvest

The average elongation at break is generally controlled within 2%. . (1) The new carding double cotton box feeder uses a pressure sensor and a variable frequency speed control motor to control the density of cotton batt in the box, so that the cotton layer fed to the card is uniform in length and width, and the sliver weight is uneven. The efficiency of the automatic winder mechanical and electrical cleaning is improved. 02 Formation and distribution of neps (1)

There are many harvesting methods during cotton harvest that will produce neps impurities in raw cotton. In recent years, After the revolution of materials and processing technology, the service life of steel rings in China has been increased to 3 to 5 years, and the traveller life has also been improved, like a fluorine-plated traveller. However, some fabrics have special hairiness, so the fabric has a certain style.Different fabric structures and weaving tensions have different shrinkage rates. (3) When the fiber is in a wet state, the fiber swells due to the immersion solution, which makes the fiber diameter larger.The shrinkage of a fabric is the percentage of shrinkage of the fabric after washing or soaking in the fabric.

Density fabrics have different shrinkage rates depending on the density. 4. The fiber also behaves differently under different conditions such as internal structure and heating temperature and time. 5. For example, the boiling water shrinkage of processed polyester staple fiber is 1%, the boiling water shrinkage of vinylon is 5%, and the shrinkage ratio of hot air is 50%. Each of these three steps will affect the shrinkage of the fabric

Long thick knots are yarn defects that are prone to occur in spinning mills, and are extremely harmful. Weaving on the cloth surface can cause rough warp weft (weaving) or cross-run defects (knitting). This kind of yarn defect is difficult to repair, and even causes defects such as cutting, drop, etc., the loss is large, and sometimes it can cause customers' economic claims. Occasional long rough spots are mainly generated in the pre-spinning and roughing process, mainly due to operating reasons, equipment and other reasons. Improper process design can also cause such yarn defects. Today, the analysis of the causes of roving yarn defects is started from the equipment such as the stripping knife rollers, roving spindles and false twisters, and roving blower blowers under the roving frame, hoping to provide some useful reference for the production management of textile enterprises. 1.
