Camouflage Has Great Potential In Vinylon Fabric.

Camouflage can be regarded as the largest military consumption. clothing On the one hand, on the one hand, officers and men have strong exercise intensity and serious wear during training. The strength of their fabrics, especially their wear resistance, has become the focus of the research team of the general Quartermaster Equipment Research Institute. On the other hand, a large amount of upgrading has made the cost control a must factor. The use of high price and high strength fibers to improve the wear-resisting properties of fabrics is obviously not practical.

At this point, the emergence of vinylon just solves the two problems of wearable strength and moderate price. "By increasing the degree of polymerization of PVA and making the fibers form dense cortices in processing, increasing drafting multiple, a high-strength polyvinylon fiber with strength of 8cN/dtex has been developed." Shi Meiwu, a professor at the military equipment Research Institute of the general post office, said in an interview with reporters that the tensile breaking strength and tear strength of the new material, especially the wear-resisting property, can be greatly improved by using this low price and high-performance high strength polyvinylon fiber as an enhancement element.

The original camouflage fabric was mixed with polyester and cotton in proportion of 65% and 35% respectively, and polyester trellis reinforced bars were used to improve the tear strength. A conductive filament was embedded in the warp spacing of about 2cm, and the pattern was Woodland Camouflage. "After continuous testing by R & D personnel, adding 20% high-strength vinylon on the basis of the original polyester cotton training clothing can increase the strength of the fabric by 30%, and the leveling resistance index has increased from 125 times of the original training standard to 900 times the new standard." Shi Meiwu used experimental data to prove the superiority of vinylon.

Why do we choose vinylon? It is learnt that the advantages of vinylon fiber are abundant resources, and have better equipment foundation and production capacity in China, and the price is relatively low, and it has good hygroscopicity and comfort. The conventional vinylon has higher strength and wear resistance, and it can significantly enhance the fabric of the training dress after high strengthening.

However, each fiber has its own advantages and disadvantages. Vinylon is no exception. Its shortcomings are that its color is not bright and its dimensional stability is poor. Under the condition of wet heating, the control of tension, temperature and time is not easy to cause hard feeling and tear strength. However, because of the camouflage pattern used for training clothes, there is not much demand for the bright gloss of fabrics.

The key to the development of the product is to optimize the dyeing and finishing process, taking into account the dimensional stability, hand feel, tear strength and wear resistance of the fabric. Shi Mei Wu Gao introduced his team's research ideas in detail. First, we optimized the fineness, breaking strength and elongation at break of the vinylon by testing, determined the proportion of the dense cortex on the surface of vinylon, and obtained the reinforced fibers with strength, wear resistance and fracture energy.

Second, in the polyester, combed cotton and high strength vinylon system, the proportion of blending is preferred, and the wear resistance, dimensional stability and comfort are taken into account.

Third, adopt the design idea of roving number and low density, the summer training clothes get good air permeability, and winter training clothes can achieve the windbreak effect by pressing light.

Fourth, summer training clothes. Fabric The quality of the square metre is small, and the two twill weave is suitable for tightness. The quality of the winter training fabric is higher than that of the square fabric. The upper part of the fabric is made of three broken twill weave, which reduces the interleaving times and keeps a good handle.

Fifth, to avoid wet high tension and high temperature processing conditions in dyeing and finishing, good dimensional stability can be achieved while hand feeling, tear strength and wear resistance can be taken into account.

Sixth, the digital camouflage pattern has a small pattern, which automatically converge to a large size pattern when viewed from a distance. It can take into account the camouflage effect of close and long distance observation. Therefore, in summer training clothing, we use the woodland digital camouflage pattern to adapt to the environmental vegetation status in summer in the north and the south. In winter, we use the desert digital camouflage pattern to adapt to the winter environmental conditions in the north.

Reasonable blending and popularization of civil service

After the expansion of production, the application of the new training clothing fabric has been expanded. The results show that the physical properties of the fabric are much better than that of the original training fabric. In terms of resistance to flat grinding, the number of wear resistant fabrics made by the product standard is 7.2 times higher than that of the original training fabric, and other properties have also been greatly improved. At present, the new training fabric has been produced in large quantities. It has good handle, dimensional stability, good printing quality and camouflage effect.

Shi Meiwu said that the uniforms and uniforms of uniforms in military uniform are the pursuit of uniform and uniform fabrics. There are various special requirements for fabrics, and strong demand, variety and harsh conditions are the difficulties of research and development. However, whether it is regular clothing, training clothes or special work clothes, it has good market application prospects and civil use. Spin The value of product promotion can play a certain role in promoting the development of civilian textiles.

"Since any fiber material has its advantages and disadvantages, reasonable use is the key to design." Shi Mei Wu further explained that vinylon fiber had been a brilliant change in the main varieties to alleviate the contradiction between grain and cotton and solve the problem of clothing for the Chinese people. However, when the polyester fiber appeared and applied, it gradually shrank and was forced to withdraw from the ranks of fiber. However, considering the physical and chemical properties, processing properties and price factors of vinylon, it is appropriate to apply it to military training clothing fabrics, and we can say that we have made the best use of them.

As an example of extended applications, researchers have developed high-strength polyvinyl alcohol protective clothing fabrics with tens of thousands of times of flat grinding. It shows that the application of high-strength vinylon will far exceed the field of training clothes and fabrics.
