[Product/Solution] Stab-proof & Bullet-proof Vest

1. Brief Introduction of Achievements

(1) This product innovatively develops a new type of stab-proof flexible aramid non-woven fabric composite material, breaking the traditional conclusion in the industry that non-woven fabric cannot be stab-proof. It has excellent puncture resistance and a simple and easy manufacturing process. The product has excellent protection performance and greatly improved comfort performance. It can be bent 180° arbitrarily. Compared with similar domestic products, it has the best comfort.

(2) This product innovatively develops a new type of stab-proof aramid non-woven fabric, optimizes the appropriate adhesive formula, and forms a flexible composite material with high stab-proof performance. This technology not only has a simple and easy manufacturing process and improved apparent performance, but also improves stab-proof performance by 15% compared with before, and shortens the drying time, increasing production efficiency by 10%.

(3) This product uses telescopic reed for initial positioning and equally spaced thread for secondary positioning to effectively position the fiber. It also creatively uses mechanical wire spreading roller to spread the fiber, ensuring that the fiber is fully spread while minimizing the damage to the fiber strength. At the same time, the traditional scraper is modified and processed to increase the ambient temperature of the scraper spray chamber, breaking through the technical indicators that cannot be achieved by using this die head scraping method in the traditional composite industry. The process methods and corresponding parameters related to the automated production of aramid non-woven fabrics are explored and determined. The equipment operates reliably, realizing the automated and large-scale production of flexible aramid non-woven fabric composite materials.

At present, the stab-proof clothing products prepared by the team have obtained the test reports of Class A and B stab-proof clothing for police stab-proof clothing and the full test reports of relevant departments. It has provided customers with products that meet the requirements and achieved good economic benefits.

2. Application fields

It can be applied to various military and civilian fields where safety protection is required.

3. Market prospects

The unit to which the achievement belongs has been developing individual protective materials for more than ten years. It is the first domestic enterprise that meets the NIJ0101 standard test of the White Laboratory in the United States, and has built one of the few continuous production lines for aramid non-woven fabrics in China. The comfortable stab-proof clothing products developed by this product's new flexible puncture-resistant material use high-performance fibers and modified adhesives to weave non-woven fabrics, so that a single structure has excellent puncture resistance. The prepared product fits the body curve, has a small thickness, good softness, and greatly improves comfort, making up for the defects of existing products. In addition, this product has the characteristics of stable performance, large safety margin, and high cost performance. It has strong market competitiveness and good scalability among similar products, with broad market application prospects and significant economic benefits.

4. Intellectual Property

A number of invention patents have been approved, all of which are held by the achievement unit alone.
