In contrast to cotton, the normal viscose fiber has a strongly diminished dimensional stability, which can be traced back in part to the low molecular weight and in part to the poorer orientation of the cellulose chains. In the new modal fibers (polynosic fibers and high-wet-strength fibers), both factors are improved by the following precautionary procedures. The... 

Uses of pulp 95% of all pulps are paper pulps , used for paper and board production, from the rest, the dissolving pulps , chemicals are made like viscose (cord rayon, modal fibers, cellulose guts, cellulose films, acetyl cellulose) or cellulose derivatives (cellulose ethers, cellulose nitrates, methyl cellulose, carboxy cellulose). The requirements concerning quality differ considerably from one application to the other. 

Natural polymers can be made into hbers through dissolution of the polymer in an appropriate solvent and then extmsion of the polymer solution into a coagulation bath. As an example, cellulose can be made into viscose rayon fibers, cuprammonium rayon, cellulose acetate and triacetate fibers, lyocell, and modal fibers depending on the processes used to make the fibers. Other natural polymers such as mbber, chitosan, alginic acid, and protein can also be made into fibers in an appropriate fiber-forming process.

In context with RR, only additives for the production of - viscose are of interest. - Sulfated oils, - fatty acid condensation products, laurylpyridi-nium salts and mainly ethoxylated products, especially fatty amines, are used as modifiers to produce high-tenacity, high-modulus viscose and modal fibers (- viscose). 

As a 1.7 dtex (1.5 den) fiber, it can be spun into yams with a better strength conversion factor than other ceUulosics, aUowing rotor-spun Tencel to outperform ring-spun cotton or modal viscose. Fabrics can be made at high efficiency, and prove to have the anticipated tear and tensUe advantages over other ceUulosics. Direct, reactive, or vat dyes can be used, and easy care properties can be achieved with less resin finish than normal. Tencel could therefore be positioned as a new premium quaUty apparel ceUulosic and not simply as a long-term replacement for viscose. 

The index of refraction of allophane ranges from below 1.470 to over 1.510, with a modal value about 1.485. The lack of characteristic lines given by crystals in x-ray diffraction patterns and the gradual loss of water during heating confirm the amorphous character of allophane. Allophane has been found most abundantly in soils and altered volcanic ash (101,164,165). It usually occurs in spherical form but has also been observed in fibers. 

The taste receptors allow for the collection of only a small amount of information, enabling us to distinguish the taste modalities, namely, sweet, bitter, saline, or acid. Responses to the true taste-receptors are produced with a high degree of probability over relatively simple pathways, containing few fibers. The cortical centers for tastes, if present at all, are small. ... 

Although some neural fibers respond to sweet-stimulus compounds placed on the tongue, others do not. This pattern of sensitivity is often a very complicated one. The fibers often respond to more than one, sometimes even to all, of the four taste modalities. Very rarely does a fiber respond specifically to only sweet or salty substances. Furthermore, other fibers may have an entirely different spectrum of sensitivities, and may respond strongly to one sweetener and very weakly to another. Pfaffmann reported how two fibers, one having one pattern of sensitivity to taste, and the other, a different pattern, can signal two different taste-qualities, even though... 

Constipation commonly occurs during pregnancy. Nondrug modalities such as education, physical exercise, biofeedback, and increased intake of dietary fiber and fluid should be instituted first.
