The _pina_ is a fiber obtained from the leaf of the anana tree (_Bromelias ananas_), and is prepared in the same way as the abaca, but extreme care must in this case be observed in culling the fibers, in order to sort in accordance with their degree of fineness. The Arabs manufacture the stuff for their tents with a mixture of camel's hair and the fibrous flocks (kind of wadding) obtained from the stalks of the wafer palm (the _Chamaerops humilis_). The tissues used by the Arabs are coarse and colored, but the palm fibers--when freed from gluten, which makes them adhere more strongly--are susceptible to divide in a most astonishing manner. The _Agave americana_ is a coarse fiber, mostly used in France for the manufacture of Gobelin carpets and the production of ropes. Great efforts have been made to bleach it in a satisfactory manner, as is done with the _Phormium tenax_, but the former kind of fiber resists the ordinary treatment with lyes, etc., and an appropriate bleaching process has only been discovered quite recently. Jute, which by many is confounded with _Phormium tenax_, or New Zealand lint, is a fiber which can be divided as finely as desired, and can be most beautifully bleached. The jute or Indian _paat_ is generally known as a fibrous and textile fabric, obtained chiefly from Calcutta, and is similar in nature to the _Corchorus capsularis_, an Oriental species, known in Oriental India by the name of _hatta jute_ and _gheenatlapaat_. This fibrous plant has the property of dividing into the finest parallel fibers, which can be carded without difficulty, and may be said to have the excellent properties of linen, hemp, and cotton at once. When properly bleached, it has an aspect which is as beautiful as that of silk. A mixture of silk and jute can be easily worked together, and can also be mixed with such vegetable fibers as cotton and linen. An immense quantity of flannel and other stuffs are now manufactured and imitated with the different mixtures containing jute. The _suun_ is a fiber of a plant in the form of a cane (_Crotalaria juncea_), and the paat or _suncheepaat_ is the thread of a species of spiral (_Corchorus olitarius_), sold under the name of jute tissues. The cotton tissues lose about twenty-five per cent. of their weight in bleaching, five per cent. of the substances are dissolved through alkalies, and the other twenty per cent., which are not attacked directly through the alkalies, are removed through chlorine, acids, and the water itself. The linen and hemp tissues contain eighteen per cent. of substances which are soluble in alkalies, and they lose from twenty-seven to thirty per cent. of their weight when taken through the consecutive bleaching operations.
