In a multimode fiber modal dispersion causes each mode to have a different velocity and reach to the end of the fiber at a different time. This will cause inter-symbol interference (ISI) which means that we need to send data at lower rates in order to prevent ISI. Lower rates means a reduction in bandwidth.
Viscose and modal both are semi synthetic fibre, where the modal has more wet strength than viscose and have less shiny than viscose
Modal is a cellulose fiber made by spinning reconstituted cellulose from beech trees. It is about 50% more water-absorbent than cotton
Rayon and Modal are cellulose fibers.

1. intermodal dispersion in multimode fibre but intrmodal in single mode.... 2.intermodal is also known as modal dispersion but intramodal is also known as material dispersion. 3.in intermadal more pulse broadning but in intramodal less pulse broadning.

Here is what it says on the Wiki page:"Modal is a bio-based fiber made by spinning reconstituted cellulose from beech trees. It is about 50% more hygroscopic, or water-absorbent, per unit volume than cotton is. It is designed to dye just like cotton, and is color-fast when washed in warm water. Modal is essentially a variety of rayon[1]."See:http://en.wikipedia.org/wiki/Modal_(textile)
Modal bandwidth
Single mode fibers have higher bandwidth than multimode. Single mode fiber equipment is more expensive than the equipment for multimode. Single mode fiber is cheaper than multimode fiber. Multimode fibers have higher capacity and reliability over short distances than single mode. Multimode fibers support more than one propagation mode unlike single fiber Multimode fibers are limited by modal dispersion whereas single mode is not. Multi-mode fiber optic cable is the earliest commercially available fiber optic cable, due to the presence of dispersion is serious, the attenuation is large, the available bandwidth is narrow, cost issues, it have exited the optical fiber network of the main battlefield platform of telecom operators . only to to retain market share at the smartbuilding fiber optic cabling. When the multi-mode fiber optic cable for video transmission, it can only meet about the farthest 3 ~ 5km transmission distance, and have great restrictions on the bandwidth of the video multiplexer(for analog modulation) and a transfer rate (for digital), which is generally suitable for short-range, small capacity, simple application occasions. Particularly greatly limited the application of non-compressed digital Optical multiplexer in the transmission distance and capacity. Single-mode fiber optic (mainly g.652 fiber) cable has become the mainstream of current optical communication transmission due to its low prices and high performance. The endless stream of new technologies in the field of optical fiber communication, whether it is a long-range, high-capacity, or business, and both are developed for single-mode fiber. Fiber optic cable service life of 20 years or more, than the Optical actual use cycle long. This is from the point of view of the strategic resources to consider the laying of fiber optic cable, it must take into account the future expansion, updated equipment, the number of cable cores enough, can continue to carry the new business.

No. Modal is an adjective and not a verb so nobody can modal anything.
How do you wash modal fabric?
