A high density mineral fibre board having a formaldehyde free binder has acceptable strength and good dimensional stability.

A rain-test resistant, high-vapor-permeable, water-repellent and water-resistant manufacturing process for making such fabrics is provided. It is used in the dyeing and finishing process of fabric in which the fabric is treated with the treatment roller, knife roller, and spray methods. These combined methods can coat water-repellent agent on the fabric and form a very thin film on the fabric. This protective film on the fabric enhances the wash resistance of the fabric while it will not adversely affect the water repellence and water resistance of the fabric. Moreover, this technique of forming a very thin water-repellent film on the fabric rules out the conventional method with which the water-repellent agent dipped within the fabric structure is easily washed out with regular laundry of the fabric due to the lesser amount of the agent being attached onto the fabric.

A method, apparatus and system is provided for both (1) decreasing electrostatic discharges to reduce the potential for incendiary discharges caused by electrostatic charges in flexible containers such as flexible intermediate bulk containers (FIBCs) and (2) decreasing the induction on isolated conductors nearby the container to reduce the potential for incendiary discharges from the isolated conductors

The present invention relates to a fibrous haemostat composition that is able to safely gradually and fully degrade in a human or animal body within about 30 days and so can be utilized by physicians to stem a flow of blood and promote healing both after as well as during surgical procedures.

The subject of the invention is a method of obtaining an antimicrobially active nonwoven fabric, which is prepared in an aqueous solution containing: from 0.1 to 30 wt % citric acid, from 0.1 to 20 wt % chitosan, from 0.1 to 15 wt % zinc oxide, from 0.01 to 3 wt % lawsone, and and preferably natural essential oils in an amount of 0.01 to 5 wt %, especially of mint or lavender. In the next step, the prepared solution is applied to the non-woven fabric, which is then dried.
