High Strength Vinylon Improves Wear Resistance Of Military Police Training Clothes

The performance requirements of military and police training clothing are mainly high strength and wear-resistant, camouflage printing, breathable comfort, smooth appearance, moderate cost, etc., which requires a variety of performance fiber coordination.

The design idea of raw materials is vinylon / polyester / cotton blended.

It is made of polyvinyl chloride to achieve high strength and abrasion resistance. It also takes into account comfort, printing and low price. It achieves fast appearance and low price from polyester, takes into account the printing effect, realizes comfort and helps printing with cotton fiber.

High strength vinylon has unique properties.

First of all, it showed excellent mechanical properties. The strength of high-strength vinylon was about 1.7 times higher than that of ordinary vinylon, and the strength dispersion degree was equivalent or slightly smaller. Elongation at break was slightly smaller than that of ordinary vinylon, and the elongation at break was less than that of ordinary vinylon.

After a reasonable selection of textile processing methods, the problem of small elongation at break can be ensured by increasing the bending degree of the fibers in the yarn and increasing the Qu Qubo height of the yarns in the fabric.

The heat resistant water properties of high strength vinylon are very important for dyeing and finishing.

Vinylon fiber is not resistant to hot water before aldehyde treatment. The RP value of high strength polyvinylon finished product can reach 113 C ~115 C.

Simulated drying process and printing and baking processing were carried out. The dry heat treatment experiment of vinylon samples in oven showed that the strength retention rate of high strength vinylon reached 94.2% ~ 99% at 175 6min, and the strength retention rate of high strength vinylon was 91.3% to 98% after 2min dry heat treatment at 200 C.

In the light aging box, the 192h xenon lamp irradiation experiments on ordinary polyester, cotton and high performance vinylon were carried out under the same conditions. The strength retention rates were: high strength polyvinylon 95%, polyester 83%, and cotton fiber 70%.

High performance vinylon has high strength, good dyeing and finishing properties, and superior to polyester and cotton light fastness.

At present, the technical indexes of high-strength vinylon produced by industrialization are: tensile breaking strength is greater than 8.0cN/dt, elongation at break is more than 12%, water softening point is more than 114 degrees C, and crimp number is more than 15 /25mm.

Fiber specifications include cotton, medium and wool products.

Various spinning methods can be used, such as ring spinning, CELO spinning, compact spinning, spun spinning, etc.

On the choice of fabric organization,

Adopt 1/1 plain pattern, spring and autumn dress adopt 2/1 twill, winter dress adopt 3/1 to break twill.

Attention should also be paid to several problems: first, pretreatment can withstand alkaline high temperature treatment; two, it is not suitable for oxygen bleaching to avoid strong and yellowing; three is suitable for reduction and reactive dyestuff dyeing, and can use overflow and long cars; four is to avoid wet high temperature stereotypes and control fabric handle; five is to use biological enzyme soap detergent technology.

At present, high strength vinylon fabric has been applied to military and armed police training clothes.

The addition of 20% high strength vinylon on the basis of the original polyester cotton Training Dress increased the strength by 30%. The leveling resistance index increased to 125 times from the original training standard 125 times to 900 times the new standard, which increased to 7.2 times.

The firmness and firmness of the actual wear are greatly improved, and it has good comfort.
