The "High Rise" Route Of New Military Carrier Fabrics

< p > from the point of view of modern war of the US Army, the number and types of soldiers carried by the soldiers are increasing and the weight can exceed 50Kg.

Such supernormal negative weight requires that the carrying fabric must have high strength and high durability, thereby ensuring the reliability of military carrying devices in harsh and complex environments.

< /p >

< p > according to the introduction, at present, the foreign military carrying fabric is mainly made of high strength nylon filament fabric, and the fiber strength is over 7cN/dtex. The main fabric is mostly 1000D, and the tensile strength is over 3000N.

Besides the high tensile strength, high tear strength and high wear resistance, this kind of fabric also has many functions such as camouflage, waterproof, oil stain prevention and so on.

Since the 90s of last century, our army has made great progress in carrying out the functional finishing of fabrics. However, the use of polyester staple and ordinary polyester filament is still the main material in the use of materials. There is still a certain gap between the fabrics in terms of strength, tear resistance, wear resistance and other key indicators.

< p > by the Li Yan, Qiu Yuhua, general engineer of the Quartermaster Equipment Research Institute, Gao Qiang Zhang Xudong and Shi Mei Wu, the high-strength and wear-resistant bags and fabrics developed by Gao Gao and Shi Mei Wu adopt the domestic high-strength polyester industrial yarn. Through the process of air pformation and optimization of weaving, dyeing and finishing, coating process, a new type of military carrying fabric with high strength, wear resistance, outstanding features, multi-function and overall index reaching the existing equipment level of the US Army has been developed. The results can be applied to the field of civil luggage and bags, and the domestic luggage carrier has already embarked on the road of high-strength high-end.

"P >" in the past 10 years, China's fiber industry has been adjusted and upgraded, and the industrialization of high-performance fibers has been effective.

However, at the application level, the development of the products with high strength fiber as the main material has not been fully started, especially in the field of military equipment application.

Li Yan said.

< /p >

< p > then, how to select the raw materials for high-strength and wear-resistant fabrics and how to determine the structure of the fabrics? "The goal of developing new fabrics is to select high-strength fibers that have been industrialized in China as raw materials, and with reasonable weaving and dyeing processes to produce portable fabrics with high strength, good abrasion resistance, good appearance and sewing performance."

Shi Meiwu said, at present, domestic high-tech fiber, including ultra-high molecular weight polyethylene fiber, high strength polyester, high strength nylon, etc.

Among them, UHMWPE fiber has the highest strength index and wear resistance, but its price is high, temperature resistance is poor, and it is difficult to dye and finish.

High strength polyester industrial yarn, high strength nylon and high-strength vinylon fiber have higher strength and moderate price. They can be dyed and processed.

< /p >

< p > in the aspect of fabric structure design, taking into account the uncertainty of the direction of destructive force in the actual use of carrier fabrics, it is advisable to adopt the design of warp and weft structure and performance.

After balancing the fabric's tightness requirements, fabric style, processing performance and processing efficiency, the researchers determined that plain weave or Fang Ping fabric with similar warp and weft density was suitable for fabric.

< /p >

< p > Zhang Xudong introduced the specific process: "because of the requirement of the air change process for the fineness of the single yarn, after determining the air variant process, we redesigned the specifications of the high-strength polyester filament from the raw materials, and optimized the spinning process and spinning oil.

Through the comparison of the previous trial production, the high strength polyester FDY with a size of 920dtex/192f is made. The monofilament fineness is not more than 5dtex, and the strength index is not less than 7.5cN/dtex.

< /p >

< p > into the dyeing and finishing part, because the high strength polyester industrial yarn has improved the dyeing and Finishing Properties of fabrics to some extent after the air treatment, but the slipping resistance between fabrics is still small, and there are many problems such as weft, splitting and so on.

Therefore, at the beginning of dyeing and finishing, ensure that the fabric is firmly sewn, and the seam is straight and even.

< /p >

< p > to ensure that the military carries good waterproofing effect, the R & D team will coat and waterproofing the fabric.

Using the technology of pre coating and waterproof, the adhesive strength of the coating and the fabric can be improved by using the coating glue, and the wear resistance of the fabric < a href= "//www.sjfzxm.com/news/index_c.asp" > fabric < /a > can be improved.

It also shows certain advantages in comparison with similar fabrics.

< /p >

< p > < strong > military civilian is beneficial to < /strong > < /p >.

< p > by comparison, the team concluded that: < a href= "//www.sjfzxm.com/news/index_c.asp" > the new military carrier fabric < /a > surpasses our army's original carrying fabric in terms of physical indicators. Compared with the existing US military equipment, the new fabric is basically the same in terms of strength index and slightly lighter in weight.

This difference is compatible with the Chinese and American armies' single soldier load standard, which can meet the reliability requirements of fabric in carrying tasks.

In the wear resistance index, there are a lot of new military carrier fabrics, but there is still a gap between them.

In addition, the color fastness to washing, abrasion resistance and brushing of the new military carrier fabric is generally 4~5 grade, and the sunlight fastness reaches 6 level, which fully meets the strict requirements of military products.

< /p >

< p > < < a href= > //www.sjfzxm.com/news/index_c.asp > > fabric > /a > practical performance verification experiment we found that the new military portable device made of high strength polyester industrial yarn ATY has better tolerance performance than the original carrier in a series of extreme reliability tests such as drag test, drop test and stab test, and the comprehensive service life is increased by more than 2 times.

Qiu Yuehua further introduced.

< /p >

The development of a new type of military carrier fabric is a useful attempt to promote high-performance fibers such as domestic high-strength polyester fiber and other industries to traditional military and civilian textiles fields. P

The equipment and use of new fabrics are a great help to the development level of our military equipment and equipment for covering cloth.

< /p >

< p > "the key to the successful development of a high-performance fabric is to start from the source of high-performance fibers and coordinate and consider comprehensively in the four key links of spinning, weaving, dyeing and finishing, so as to comprehensively improve the processability and performance of products."

Through the research and development of new fabrics, the R & D team is deeply touched by the importance of industrial chain collaboration.
