PRODUCTION OF FIBER WEBS USING AIRLAID NONWOVENS
Nonwoven fiber webs are produced by spraying one or more aqueous binder formulations containing one or more polymers selected from the group of vinyl ester polymers and (meth)acrylic ester polymers, and in a separate step, spraying one or more aqueous silicone formulations containing one or more polysiloxanes, onto the surface of an airlaid nonwoven.
SURFACE MINERALIZED ORGANIC FIBERS AND METHODS OF MAKING THE SAME
A method of making a mineralized fiber having a fiber core and a calcium carbonate shell can include admixing fibers with green liquor and adding CaO to generate a causticization reaction that results in a calcium carbonate shell coating forming around the fibers.
Porous polymeric cellulose prepared via cellulose crosslinking
The invention relates to porous polymeric cellulose prepared via cellulose crosslinking. The porous polymeric cellulose can be incorporated into membranes and/or hydrogels. In preferred embodiments, the membranes and/or hydrogels can provide high dynamic binding capacity at high flow rates. Membranes and/or hydrogels comprising the porous polymeric cellulose are particularly suitable for filtration, separation, and/or functionalization media.
NON-FLUOROCARBON LAUNDRY TREATMENT PROVIDING ENHANCED FLUID REPELLENCY
Non-fluorocarbon compositions for providing enhanced fluid repellency on various surfaces, including for laundry treatments in a finishing step of a laundry process, are disclosed. Non-fluorocarbon laundry treatment compositions and compositions including the non-fluorocarbon chemistries and a substrate surface are also disclosed along with methods of using the same in a laundry application.
Algae-derived flexible foam, and a method of manufacturing the same
This document presents algae-derived antimicrobial fiber substrates, and a method of making the same. The fiber may be a synthetic fiber, but can also be formed as a cellulosic (e.g., cotton). In various implementations, an algae-derived antimicrobial fiber substrate can be made to have identical properties and characteristics of nylon-6 of nylon 6-6 polymer or the like, and yet contain antimicrobial, anti-viral, and/or flame retardant algal derived substances. Any of various species of red algae, brown algae, blue-green algae, and brown seaweed (marine microalgae and/or macroalgae) are known to contain a high level of sulfated polysaccharides with inherent antimicrobial, antiviral, and flame-retardant properties, and can be used as described herein. Additionally disclosed are algae-derived flexible foams, whether open-cell or closed-cell, with inherent antimicrobial, antiviral, and flame resistant properties. Further, a process of manufacturing is presented wherein the process may include one or more of the steps of: harvesting algae-biomass; sufficiently drying the algae biomass; blending the dried algae biomass with a carrier resin and various foaming ingredients; adding an algal-derived antimicrobial compound selected from various natural sulfated polysaccharides present in brown algae, red algae, and/or certain seaweeds (marine microalgae); and adding a sufficient quantity of dried algae biomass to the formulation to adequately create a fire resistant flexible foam material.
Structural and decorative composite material, preparation method therefor, and article containing same
Provided are a composite material and a preparation method therefor. The composite material comprises: a base layer; a first plant fibre fabric located on the upper surface of the base layer; optionally, a second plant fibre fabric located on the lower surface of the base layer; and resins present in each layer.

Ambient humidity control article
An ambient humidity control article for controlling ambient humidity within 55%-68%. The article includes a substrate having a predetermined water absorbability, and a humidity control layer coated on the substrate and made up of a humidity control composition. The amount of the composition coated on per cubic centimeter of the substrate is 0.54-0.74 grams. The composition includes water and at least one of citrate, lactate and formate. The citrate is at least one of sodium citrate, potassium citrate and calcium citrate. The lactate is at least one of sodium lactate and potassium lactate. The formate is at least one of sodium formate and potassium formate. The weight percentage of each of the citrate, lactate and formate in the composition is 33.3%-84.2%. The water absorption amount of the substrate is not less than 0.5 grams per cubic centimeter.
Nanofibrillated Cellulose Fibers
A spray dried non-hydrogen bonded (NHB) nano-fibrillated cellulose (NFC) composition and methods for preparing such composition are disclosed. The spray dried NFC with a NHB effect results in low packing density.
Online ordering and just-in-time manufacturing of laser-finished garments
An on-demand manufacturing of apparel system includes online customization and ordering of garments, previewing of the garments, manufacturing including laser finishing of garments, and delivery to the customer. Laser finishing of apparel products reduces finishing cost, lowers carrying costs, increases productivity, shortens time to market, be more reactive to trends, reduces product constraints, reduces lost sales and dilution, and more. Fabric templates can be used to produce a multitude of laser finishes. Operational efficiency is improved.
METHOD FOR CONSOLIDATING A FIBROUS MATERIAL WITH A BIO-BASED BINDER POLYMER, A CONSOLIDATED FIBROUS MATERIAL AND AN AQUEOUS BINDER SOLUTION
A method for consolidating a fibrous material of plant-based fibers, such as cellulose fibers and/or poly-lactic acid fibers, the method including: applying to the fibrous material an aqueous solution including a cellulose derivative, and/or a salt thereof, and an acid, the aqueous solution having a pH within the range of from 3 to 7, optionally within the range of from 3 to 6, optionally within the range of from 3 to 4.5; and drying the bonded fibrous material, optionally at 100° C. or higher. Also, a fibrous material formed by the method, an aqueous binder solution including a cellulose derivative, and/or a salt thereof, and an acid, and a nonwoven material including airlaid plant-based fibers being consolidated by a bio-based binder in the presence of a carboxylic acid, the bio-based binder being a cellulose derivative, and/or a salt thereof.
