Your right I mix the two. Here's more about hair than anyone need know it relates to stillness of horse/hog/etc
THE basis of all curled hair made is horse hair, cattle
I hair and hog hair. Horse hair comes from horse
tails and manes, and there is a wide difference in the value and usefulness of tail hair and mane hair. Horse tail hair is stiff and straight, and its longer staple is used for hair cloth which goes into the lapels of coats for stiffening purposes, in which case it is woven with cotton thread; in some instances it furnishes its own woof and warp, in the making of a pure hair cloth with which to cover upholstery. It is also hackled or drawn into various lengths of brush hair, and is particularly suitable for this use because it lies straight and withstands the elements as well as oils and alkali soaps.
Probably the most important use of horse tail hair is as a basis for curled hair. Its stiffness when in spiral form gives it a great range of resiliency, and its ability to withstand constant depression and subsequent release, as well as its immunity to the deteriorating influences of the elements, makes it particularly good as a long lived upholstery filler.
Horse mane hair is less valuable than horse tail hair, because it is much softer, and its range of resiliency is much less. On the other hand, its affinity for other types of hair when mixed therewith makes it a good binder when used with cheaper, shorter hairs in various curled hair mixtures, and although of less value and less downright worth, it performs its function as above described well. Horse mane hair, because of its soft contact when used in curled hair, has recommended itself to a great many people as an upholstery filler, and has been in particular demand by our Government in the making of Navy mattresses.
Cattle tail hair, or the hair coming from the tassel at the end of the cattle tail, furnishes a most desirable curled hair material, in that it is longer lived than horse hair, possesses a wider range of resiliency, develops less breakage and is neither as hard as horse tail hair nor as soft as mane hair but rather a happy mean between the two.
Hog hair is obtained at the time of the slaughter of the animals and is thoroughly cured and sterilized before being used in the manufacture of curled hair. Hog hair is less valuable than horse and cattle hair only because of its shorter staple, and is used in various formulae to assist in the reduction of price. If one were to take a piece of horse hair of the exact size and length of the hog hair, he would find them both of equal value, and the horse and cattle hair are therefore only more valuable than hog hair because of their greater length and the possibility of placing more convolutions in each long hair than one can in a short hair, thus increasing the range of resiliency in a mass of curled hair.
