News unleash on polyose Fiber Research: September-2018

Cellulose Fibers Stronger Than Steel

A Swedish-German analysis team has successfully tested a replacement technique for the assembly of ultra-strong saccharide fibers at DESY’s analysis lightweight PETRA III. The novel procedure spins terribly strong filaments from little saccharide fibrils by dimensioning tired parallel throughout the assembly technique. The new technique is reportable inside the scientific journal Nature Communications.

“Our filaments are stronger than every Al and steel per weight,” emphasizes lead author academician. Fredrik Lundell from the Wallenberg Wood Science Center at the Royal Swedish Institute of Technology KTH within the metropolis. [1]

Estimation of Acid-Hydrolyzed polyose Fiber Size Distribution with Exponential and Rosin-Rammler (R-R) Laws

A new technique was developed to characterize the saccharide fiber (hardwood dissolving pulp) size distribution once fifty wound tumor virus vitriol reaction at entirely completely different reaction temperatures with exponential and Rosin-Rammler (R-R) laws. The results show that the two on prime of laws could also be effective to clarify the saccharide reaction technique. The exponential and additionally the R-R laws were found to be fitted to the vitriol hydrolyzed saccharide fiber length distribution. The additive selection distribution from Fiber Tester was shown to suit the exponential distribution well, whereas the additive mass distribution obtained from the acid reaction was found to be acceptable to the R-R law via associate approximation technique.

Method and equipment for manufacturing microfibrillated polyose fiber

Method for producing microfibrillated cellulose(MFC), whereby the maneuver comprising the steps of: Pre-treating of chemical pulp, such that, the pulp reaches a Schopper-Riegler (SR) value above fifty, and purification the pulp, at a consistency of 3-6%, in associate degree passing worker with worker blades, whereby the height of the worker blades is inside the terribly 2-3 metric linear unit.

Cellulose fiber and technique for manufacturing polyose fiber

A carbohydrate fiber keep with the invention can be a carbohydrate fiber throughout that chemical groups of carbohydrate drawn by the following formula (1) unit substituted with a boronate compound cluster drawn by the following formula (2), and includes a minimum of 1 in each of: a form one structure throughout that chemical groups of a minimum of 1 of the unit structures a and b of constant carbohydrate molecular chain n of the carbohydrate unit substituted with the boronate compound cluster; a form a try of structure throughout that radical groups of every unit structures a and b of constant carbohydrate molecular chain n of the carbohydrate unit substituted with the boronate compound group; and a form 3 structure throughout that radical groups of varied carbohydrate molecular chains n of the carbohydrate unit substituted with the boronate compound group, whereby carbon thereto the chemical groups to be substituted with the boronate compound cluster unit secured {is two|is a try of} carbon atoms chosen from the carbon atoms at positions a pair of, 3, and vi of the unit structures a and b.
