Problems solved by technology

[0004] The problem with these types of barriers is that they are bulky, heavy, thick, difficult to install and expensive to produce
However, these barriers suffer from the following disadvantages: For example, due to the adhesive used in the laminated structure, these barriers are relatively stiff and lack flexibility
In addition, these barriers can be less breathable, denser, and delamination can occur

example 1

[0042] Anti-invasive fabrics were tested according to the standard "HOSDB Slash Resistance Standard for UK Police (2006)" Publication No. 48 / 05 (which is incorporated herein by reference).

[0043] Guided landing devices designed using HOSDB (such as figure 1 shown) was tested on an external stand-alone facility. This device enables the chopping projectile to fall under the influence of gravity and contact a predetermined point of the chopping plate, which is arranged on a force platform installed at an angle of 2° to the vertical. Appendix A of the standard "HOSDB Slash Resistance Standard for UK Police (2006)" Publication No. 48 / 05 gives details of the setup and calibration of the test equipment for calibration tests on HOSDB certified test equipment. Examples of test data obtained using fabrics produced according to the invention under different process conditions are listed in Table 1a. Reference data obtained with fabrics produced without the use of knitted wire mesh ar...

example 2

[0049] Two carded and cross-laid webs were prepared from 100% PPTA fibers (para-aramid) and placed on either side of a knitted metal mesh made of hardened and annealed, Composed of twin strands with a diameter of 0.28 mm. The area density of the first fiber layer is 50g / m 2 , the areal density of the second fiber layer is 150g / m 2 . The surface density of the knitted metal mesh layer is 1800g / m 2 , which consists of annealed and hardened twin strands. After pre-wetting to evacuate the air in the fibrous layer, the above-mentioned three-layer construction was hydroentangled using 5 jets with a certain water jet pressure profile, where the maximum pressure was 220 bar (2.2 MPa). Dry the fabric in a through air dryer. The cut resistance of the resulting fabrics was tested at an independent facility according to EN388:2003 (6.2 Knife edge cut resistance) and EN ISO 13997:1999. The blade type used was GRU-GRU88-0121 and the sharpness correction factors were 0.839 and 0.822. ...

Abstract

A reinforced fibrous material and production method and use thereof are described. The reinforced fibrous material comprises one or more nonwoven fabric layers entangled with a metallic mesh layer, methods for its preparation and uses thereof.

Description

technical field [0001] The invention relates to a novel reinforced fiber material, its preparation method and its use. [0002] More specifically, the invention relates to the use of this novel reinforcement material as an intrusion resistant roller blind. The term "intrusion resistance" is intended to include slash resistance, and optionally heat resistance or flame retardancy. Background technique [0003] Currently, when any area (for example, a cupboard, shelving or kiosk, whether it is used for tobacco sales, alcohol or other retail products, or for a bank desk, etc.) requires restrictive, preventive or protective Shutter type shelters are used to avoid approaching. Typically, such louver-type shelters are screened screens of transversely mounted interconnected metal laths or slats. This slatted shelter moves between vertical rails on either side. The slatted screen slides inside the rails and when not in use is rolled up on a spring-loaded reel inside the box-like ...
