FLAME OR FIRE RETARDING AGENTS AND THEIR MANUFACTURE AND USE
The invention relates to an agent, in particular a flame retarding agent and/or a fire retarding agent, for reducing the combustibility and flammability of various materials or matters, e.g. like wood and wood products, textiles, paper, cardboard, fibers and fabrics, paints, including composites and/or composite materials therewith, the manufacture of the composition and methods of using the agent and/or the corresponding combination of its constituents to reduce combustibility and flammability. An exemplary composition in dry form (powder) for 1 l of aqueous solvent, in particular for 1 l of water, contains borax in an amount of 30 to 70 wt.-%, boric acid of 30 to 70 wt.-%, sodium chloride (NaCl) in a maximum amount of less than 5 wt.-%, and, if desired, urea in an amount up to 5 g; based in each case on the composition as 100 wt.-%. However, the compositions are preferably free from urea.
Antimicrobial textile products and method of obtaining thereof
The present invention relates to a method of obtaining antifungal, anticandidal and antibacterial textile products. The objective of the present invention is to obtain an antimicrobial product, which enables to reduce the infectious diseases that are transmitted or spread by textile products, reduces extra cost and energy spent for ensuring hygiene, and increases hygienity of disposable textile products. A solution of triclosan, chlorhexidine and disodium octaborate pentahydrate is used in the method of the present invention. The said solution enables the hydrophobic textile products to be transformed into hydrophilic products and thereby enables the antimicrobial agents in the solution to be coded into the textile products.

NANO-BORON FOR TEXTILES
The present disclosure relates to textile coatings, and to nanometer sized particles of boron in solution used for textile coatings. In one embodiment, a nano-boron textile coating is comprised of a solution including silicon, a dispersant, a softener, and acetic acid mixed in water; and a plurality of nano-boron particles dispersed in the solution. A textile with an applied nano-boron textile coating, and a process for preparing and applying a textile coating are also disclosed.
FLAME RETARDANT COVER
Flame retardant covers for mattress and flame retardant mattresses are provided. At least a portion of the fibers, yarns or the fabric of the covers is treated with a blend comprising a flame retardant compound such as ammonium phosphate. The covers do not further require any flame barrier element such as fiberglass or silica-loaded rayon. The mattresses provided herein fully comply with the federal mattress flammability standards of 16 C.F.R. 1632 and 1633.
FLEXIBLE, FLAME-RETARDANT COMPOSITE MATERIAL
A flexible, flame-retardant composite material includes a fabric layer; and at least one impregnated or coated Polyvinyl Butyral (PVB) coating layer, which is integral with said fabric layer. The PVB coating layer contains 20 to 60% by weight of PVB, at least one plasticizer in an amount of 5 to 40% by weight of the coating layer, and at least one flame retardant in a total amount of 5 to 75% by weight with respect to the coating layer. A manufacturing method thereof is also described, and includes an impregnation or coating of a water-based dispersion of PVB onto the fabric layer, and a further curing.
METHOD FOR PREPARING SALT-RESISTANT AND DETERGENT-RESISTANT ALGINATE FIBER
A method for preparing a salt-resistant and detergent-resistant alginate fiber by contacting and infiltrating a finished alginate fiber with a borate-containing adjuvant solution and using selected proper raw materials in selected proportions and reaction conditions. The preparation method solves the problem that the alginate fiber and a fabric made therefrom are neither salt-resistant nor detergent-resistant. The borate-modified alginate fiber and a fabric made therefrom have excellent salt resistances, and can be washed with an alkaline detergent. The swelling degree of the alginate fiber modified by the adjuvant solution can be reduced to 39.8% after the fiber is immersed in a normal saline at 30 C. for 72 h and can be reduced to 55.3% after the fiber is immersed in a standard detergent for 24 h, while the fiber maintains its original morphology without any obvious dissolution phenomenon, and the self flame-resisting performance of the alginate fiber is also maintained.
Cellulose fiber and process for the production thereof
The invention concerns a cellulose fiber of the genus Lyocell which is treated with a cross-linking agent, with the cross-linking agent inducing a protection from fibrillation on the fiber and exhibiting the following properties: the protection from fibrillation induced by the cross-linking agent changes if the fiber is stored within a pH range from 4.0 to 10.0, in particular under the influence of moisture and/or heat, within the pH range from 4.0 to 10.0, an optimum value exists at which the stability of the protection from fibrillation induced by the cross-linking agent during storage is highest a suitable range exists around the optimum value in which the stability is reduced by 20% at the most, compared to the stability at the optimum value, within the pH range from 4.0 to 10.0, the suitable range is limited by at least one limiting value at which the stability is reduced by 20% compared to the long-term stability at the optimum value and with a further decrease in stability occurring below and above said value, respectively, and the cross-linking agent has the capability to change the pH value.
The fiber according to the invention is characterized in that the fiber comprises a buffering substance in the suitable range and exhibits a buffer capacity of at least about 12 mmol/kg fiber, preferably from about 15 to about 70 mmol/kg fiber, in the suitable range.
