METHOD OF PRODUCING STOCKINGS FOR VARICOSE VEINS Filed June 30, 1949 'A W 0W M/M ATTORNEY Patented June 16, 1953 METHOD OF PRODUCING STOCKINGS FOR VARICOSE VEINS Albert Emile Joseph Marie Neumager, Montceaules-Mines, France, assignor to Varinyl, Montceau-les-Mines, France, a French company Application June 30, 1949, Serial No. 102,314 In France July 19, 1948 Knitted material used for stockings and the like articles of hosiery worn my people havi varicose veins are executed'usuall-y with thread that has a foundation of rubber and textile fibre, and the rubber or gummy Substance contained therein provides for their elasticity but at the same time makes them unpleasant to wear and unhealthy on account of their imperviousness. What is more, from the very nature of such stockings, they are liable to deteriorate when not worn. Furthermore, on account of their thickness and the way in which they are fashioned, such stockings have a somewhat rough appearance so that ordinary stockings have to be worn over them.

My invention removes these drawbacks and it has for its object a stocking for varicose veins that is made up just like any other ordinary stocking of finely knitted mesh. This is a light weight, sturdy article, pleasant to wear, there is no restriction to the range of coloring that may be selected and customers may indulge in any particular fancy to keep abreast with the fashions and chiefly it has the indispensable characteristic for stockings of this kind used in the treatment of varicose vein troubles i. e.

it is really an elastic stocking.

A stocking according to the present invention is illustratively exemplified in the accompanying drawing, which shows a side elevational view of a full length stocking having a foot portion l0, leg section II and open top I2.

It is a well known fact that there are threads with a foundation of polyamides that possess an extraordinarily high degree of durability, strength and more particularly of elasticity; the object of my invention is the adaptation of these polyamide threads to the fashioning of stockings for those afilicted with varicose veins.

For this purpose, the knitting of these stockings is carried out in a room kept under invariable moisture conditions with superpolyamide threads that have been subjected to twisting, that have been allowed to freely shrink with the twist fixed and then untwisted, sized and steamed; they are then milled and colored to the desired tint.

The superpolyamide thread is delivered in reels, after it has undergone a process of twisting, proper shrinking, fixing, untwisting that enables it 'to assume later a fieecy appearance and feel, together with elastic and heat insulating properties that are several times greater than those of the original thread and, finally, resizing in view of the later handlings. The twist is fixed after the shrinking.

6 Claims. (01. 66-178) After being steamed, the material is then knitted in a room kept under constant moisture conditions, the knittingmay be done on circular stocking frames or rectilinear knitting machines. The knitted stocking is milled which, as a result of its previous treatments, gives it a crepe effect, and consequently the desired elastic quality. It may finally be dyed, the coloring operation may follow after the milling or be done at the same time. Milling is the mechanical action of bathing the fabric in water containin a fatty material such as soap, to eliminate completely the sizing and so to free the thread from all restriction so that each can freely take, with respect to the others, the place which suits it.

This particular type of stocking is knitted just like the usual stocking and has a dainty enough appearance to avoid the necessity of having to wear another stocking to cover it. The superpolyamide thread has an astonishing degree of elasticity and from this point of view it is just as good as stockings made of some rubbery material and textile fibre, it keeps the veins compressed in proportion to their tendency to swell out when the wearer becomes tired. Finally, by reason of the elimination of the rubbery constituent, this stocking that shows no sign of deterioration when not worn is a very healthy article and enables the skin to breathe as well as with a stocking made of any artificial textile thread.

Naturally, my invention is not in any way restricted, for the fashioning of this stocking, to the single treatment of the thread that has been more particularly shown; it takes in, on the other hand, all methods for obtaining a stocking in which use is made of superpolyamide thread for the comfort of those suffering from varicose veins.

It is possible also to use simultaneously with the superpolyamide a thread of a different nature.

What I claim is:

l. A method for producing a stocking for varicose veins consisting in twisting a superpolyamide thread, allowing same to shrink freely, fixing the twist, untwisting the thread, sizing it, steaming the thread and knitting the stocking with said thread under constant hygrometric conditions.

2. A 'method for producing a stocking for varicose veins consisting in twisting a superpolyamide thread, allowing same to shrink freely, fixing the twist, untwisting the thread, sizing it, steaming the thread and knitting the stocking with said thread and a thread of a different nature under constant hygrometric conditions.

conditions, milling and dyeing the stocking ob' tained.

4. A method for producing an article of hosiery to be worn in contact with varicose eins consisting in steaming a superpolyamidic thread that has been twisted, allowed to shrink freely, fixed, untwisted and sized and knitting the desired article of hosiery with the steamed thread under constant hygrometric conditions.

5. A method for producing an article of hosiery to be worn in contact with Varicose veins consisting in steaming a superpolyamidic thread that has been twisted, allowed to shrink freely, fixed, untwisted and sized, and knitting the desired article of hosiery with the steamed thread associated with a thread of a different nature under constant hygrometric conditions.

6. A method for producing an article of hosiery to be worn in contact with varicose veins con- 4 sisting in steaming a superpolyamidic thread that has been twisted, allowed to shrink freely, fixed, untwisted and sized, and knitting the desired article of hosiery with the steamed thread under constant hygrometric conditions and milling and dyeing the piece of hosiery obtained.
