Flame Retardant Effect Is Expected To Be 11.3 Times Higher Than That Of Carbon Nanofiber Coatings.

Recently, the National Institute of standards and technology and Dezhou agricultural machinery University jointly developed a new type of carbon nanofiber filler, which is currently used for upholstered furniture and

Of

The flame retardant effect of the coating is more than 1.6 times, or even 11.3 times higher than that of the coating.

In addition, according to the test results, the carbon foam containing carbon nanofibers (usually through polymer nanofibers through the oxidation and high-temperature sintering of carbon chain nanofibers, with high strength modulus) and polymer thin layer of polyurethane foam fire safety is higher.

Air jet spinning can spin 30-7.4tex (20-80 branch) yarn, which is suitable for pure spinning and blending of chemical fiber and cotton.

Because of the special spinning mechanism of air-jet spinning, the structure and performance of air-jet yarns are obviously different from those of ring yarns. Their products have unique styles.

Characteristics of jet spinning and its products:

1, spinning speed is high.

The air jet twists, without high speed rotary parts (such as ring travellers), achieve high speed spinning. The spinning speed can reach 120-300 M / min, and the output per head is equivalent to 10-15 times that of ring spinning.

2, the process is short.

Compared with ring spinning, air-jet spinning reduces 2 processes of roving and cheese, and saves about 30% of the plant area.

Compared with ring yarns, 10000 spindles were employed for 90 workers, a reduction of about 60%, and the material consumption of machines was about 30% lower than that of ring spinning.

3, the product quality is good, has the characteristic.

The comprehensive evaluation of air-jet yarn quality is better. Besides yarn strength is lower than ring spinning low 5-20%, other quality indexes are better than ring yarn.

The physical properties of air-jet yarns are better than those of ring yarns, such as dry CV value, thickness and yarn defects.

The hairiness of 3mm is less than that of ring yarn. Although the yarn strength is lower, the strength irregularity is lower than that of ring yarn.

Weaving for new looms such as rapier looms and air-jet looms can increase loom production efficiency by more than 2%.

The quality of air-jet spinning is similar to that of ring yarns. Besides, the air-jet yarn has its own unique characteristics. The friction coefficient of air-jet yarn is large, the yarn has directivity, and its friction property is also directional.

Wear resistance is better than ring yarn, but the handle is hard.

Air jet spinning can also be applied to some special kinds of yarn, such as flower yarn, core spun yarn, blended yarn, etc.

4, varieties adapt widely.

Air-jet yarns can be knitted products and woven products.

More applications are: knitted T-shirt products, uniform and full plump, no skew, less streaks, less dry defects, anti pilling, cool and breathable, strong sense of three-dimensional; bedding, using air-jet yarn good and firm characteristics, you can get cloth evenly, thick handle, well ventilated effect; leisure products, such as: double faced casual wear, sportswear and so on.

According to the characteristics of air-jet yarns, we can develop products of unique style.

If the air jet fabric is rigid and rough, it can be processed into imitation hemp fabrics, crepe fabrics, imitation wool products and so on.
