  Lyocell - Wikipedia, the free encyclopedia
Lyocell is a fibre made from wood pulp cellulose.
Some main characterisitcs of lyocell fibers are, soft, absorbent, high strength when wet or dry, resistan to wrinkles, can be machine or hand washed or drycleaned, has good drape and can be dyed many colors as well as simulate a variety of textures like suede, leather or silk.
Lyocell can be blended with a variety of other fibers such as silk, cotton, rayon, polyester, linen, nylon, wool, and polyester.

 Lyocell
Lyocell is the first new generic fiber in decades and the fiber was first introduced in 1990s.
Lyocell fibers are produced by solvent spinning in which cellulose polymers are dissolved in amine oxide and spun into a well-diluted bath of the solvent.
Lyocell is a kind of soft, strong and absorbent fiber that might fibrillate under certain conditions such as abrasion during wet processing.

 How lyocell is made - Background, Raw materials, The manufacturing process of lyocell, Quality control
Lyocell is a manmade fiber derived from cellulose, better known in the United States under the brand name Tencel.
Lyocell, rayon and acetate are based on the cellulose in wood pulp, and so these are often designated "natural" fibers, though the fibers would not occur except for a manmade process.
The main ingredient of lyocell is cellulose, a natural polymer found in the cells of all plants.

 About Tencel and Lyocell
Lyocell is a natural, man-made fiber produced in an environmentally-friendly process from wood pulp that has become popular in clothing because it is absorbent and comfortable for wear, especially in conditions of high humidity.
Lyocell is stronger than cotton or regular viscose rayon and does not lose strength when wet as viscose rayon does.
Lyocell fiber is eco-friendly since products made from it can be recycled and lyocell is biodegradable because it is a cellulosic fiber; however it will not break down completely if it is disposed of in a landfill.

 Imaged nonwoven fabric comprising lyocell fibers - Patent 7008889
The present invention is directed to nonwoven fabrics, and more particularly to nonwoven fabrics comprised of a blend of matrix fibers, lyocell fibers and fusible binder fibers, the nonwoven fabric being formed on a three-dimensional image transfer device and exhibiting a durable, drapeable performance.
Lyocell is a natural cellulosic fiber spun from an amine oxide solvent developed by American ENKA, Asheville, N.C. in the late 1970's.
In particular, the present invention contemplates that a nonwoven fabric is formed from a precursor fibrous web, which is subjected to hydroentanglement on a moveable imaging surface of the three-dimensional image transfer device, and dried to heat-bond the fabric bond.

 Process for melt blowing continuous lyocell fibers - Patent 6306334
Lyocell is an accepted generic term for a fiber composed of cellulose precipitated from an organic solution in which no substitution of hydroxyl groups takes place and no chemical intermediates are formed.
The surface of each fiber produced by the process tends to be pebbled, as seen at high magnification, and the fibers have a cross section of varying shape and diameter along their length, have significant natural crimp, are resistant to fibrillation under conditions of wet abrasion, and have excellent dyeability.
Lyocell fibers having deniers in the cotton fiber range (about 10-20.mu.m in diameter) were easily and consistently produced by melt blowing at throughput rates greater than 1 g/min of dope per orifice.

 Effect of cellulose pulp type on the mercerizing behavior and physical properties of lyocell fibers | Manufacturing ...
In the case of lyocell fibers, however, the differences in the physical properties of the fibers resulting from the spinning dope phase are not as noticeable as for PPTA [4].
The spectra for the IPS lyocell fibers prepared from different compositions of cellulose pulps are similar, indicating that the origin of the cellulose pulp seems to have little effect on the crystalline structure of the resultant lyocell fibers.
IPS lyocell fibers with desirable physical properties may be prepared by selecting the kind of cellulose pulp as raw material and by optimizing alkali concentration during mercerization.

 Evaluating the Physical and Fabric Hand Characteristics of Lyocell Fabrics Made with Different Wood Pulps Textile ...
For lyocell fabrics made from yarns with higher CV%, the results are more favorable for increasing the hand values of numeri, fukurami, sofutosa, and shari characteristics, and such fabric hand as a total is an important requirement for women's suit fabrics.
In this research, lyocell fabrics made with four different kinds of commercial wood pulp are evaluated in terms of their physical characteristics and their hand values measured with the Kawabata Evaluation System for Fabrics [8].
The purpose of this research is first to examine whether or not variations in wood pulp impart differences in the physical characteristics of lyocell fabrics and their intermediates, and second to investigate whether or not these variations in wood pulp affect the suitability of fabrics for specific garment types.

The FTC rules and regulations under this statute set out the definitions of the various names that can be used, as well as the process a manufacturer must go through to establish a new generic fiber name.
In April 1992, the FTC issued a temporary designation which allowed Courtaulds to market the fiber without calling it “rayon.”; Courtaulds subsequently performed various tests, submitted the results to the FTC, and in November 1995 the FTC published a notice in the Federal Register seeking public comment on the petition.

 Cellulose Sausage Skins via the Lyocell Process
By contrast, the new Lyocell process, developed by scientists at the Fraunhofer IAP together with Teepak NV is a far less complicated method that creates no by-products, and is cost effective as the manufacturing process is significantly shorter.
So if German sausages taste even better in the future, it could be thanks to the Lyocell prose: enabling the full flavours of the meats to be developed and preserved while not adding any unwanted by-products.
Meanwhile, the researchers are looking beyond sausages with the technology - they are also applying the process in the manufacturing of a wide variety of different products, including textiles, specialty papers and other meat packaging.
