CORROSION RESISTANT YARN AND FABRIC Filed July 1, 1938 INVENTOR B05597 STU/4P7 OWf/YS ATTORNEYS Patented June 3, 1941 UNITED STATES PATENT: OFFICE 2,243,917 CORROSION RESISTANT YARN AND FABRIC Robert Stuart Owens, Brooklyn, N. Y.
Application July 1, 1938, Serial No. 216,990
2 Claims.
The present invention relates to yarns and fabrics which are resistant to corrosive fluids.
In filtering corrosive liquids it is important to have filter cloth which will be stable against the action of the materials filtered. Filter cloths made of spun glass yarn are satisfactory for use with some corrosive materials but the glass is attacked by caustic alkalies and some other corrosive liquids.
The invention has for an object to provide an improved yarn and fabric which is stable to the action of corrosive material such as acids, alkalies and organic solvents.
A further object is to provide an improved inextensible flexible tension member, which is stable against the action of corrosive materials with which the same is to be used.
Another object is to provide an inextensible flexible member which can be woven into fabric to provide a flexible filter fabric which is stable against the action of acids and alkalies.
Another object is to provide a yarn formed of spun glass having a covering which protects the glass from the action of caustic alkalies in which it may be used.
A still further object is to provide an improved glass yarn and fabric made therefrom having an improved resilient binder which permits relative movement of the glass fibre to provide a flexibility of the yarn.
The nature and objects of the invention will be better understood from a description of illustrative embodiments thereof for the purpose of which description reference should be had to the accompanying drawing forming a part hereof and in which- Figure 1 is an enlarged view of a yarn illustrating a preferred embodiment of the invention,
Fig. 2 is a perspective view of a filter illustrating one use of a fabric embodying the invention, and,
Fig. 3 is an enlarged detail view of the filter cloth shown in Fig. 2.
Referring more particularly to the drawing the yarn 5 is formed of inextensible fibrous material 6 which is bonded with a. binding material I sufllciently yielding and resilient to permit the desired flexing and relative movement of the fibres together with a coating 8 of flexible composition which is stable against the action of the corrosive material in which the yarn is to be used.
The fibrous material is preferably spun glass which has many special advantages, but for certain uses it may be of other fibrous material, which is sufficiently stable to the action of the corrosives with which the yarn is to be used, such as vinyl resin fibre, Bakelite fibre or other equivalents. Various binding materials may be used or the binding material may be omitted and the coating may be relied upon to sufliciently bind the fibres and may serve both as a binding material and a coating material. If used the binding material should be suificiently resilient and yielding so that the desired flexibility of the yarn will be retained. As suitable materials suitable rubber cements, Plexigum (acrylic resins), nitrocellulose cements, and suitable cements made from natural and artificial resins may be used. The coating composition is preferably rubber, chlorinated rubber and the like, of a composition such that it is not attacked by acid, alkali or other commonly used chemicals to which it will be exposed. Certain rubber substitutes such as polymerized chloroprene, Thiokol (polymerized ethylene poly-sulfide), Korolac (a polymerized vinyl halide), and the like may be used if and when they satisfy the requirements of the use to which the yarn is to be put. Also other suitable flexible acid or alkali resistant compounds may be used when selected in accordance with the use under consideration. The binder 1 and the coating 8 preferably are selected of such character that a firm bond is formed therebetween. The binder thus constitutes a primer coat between the glass or other fibre and the outer protective coating.
The rubber used may be of various types as, for example, latex emulsions of the vulcanizing or pre-vulcanized type. It may be applied as a rubber solution or may be applied by moulding.
The coating may be applied under pressure to cause effective impregnation into the voids between glass fibres thus providing a cushioning between the fibres and increasing the resistance to breakage under fiexure.
The yarn is adapted to many uses; for example the doctor, brush or swab used in touch-up work in electroplating may be made of this yarn.
The yarn shown is especially adaptable as a tension member for various uses in corrosive liquids and for use in the manufacture of filter fabric for filtering corrosive materials. In Fig. 2 a filter fabric 9 formed of the yarn illustrated is shown secured to a filter ill by means of a tension member or yarn I I.
The woven fabric 9 formed of the rubber coated yarn is substantially more serviceable than a glass filter especially for filtering caustic alkali. Glass itself is attacked by the action of caustic alkali and because of the fineness of the glass cellulose cements and cements made from resins, and, bonded to the binder, a. cover of rubberlike material of the group consisting of rubber, chlorinated rubber, polymerized chloroprene, polymerized ethylene poly-sulfide and polymerized vinyl halide.
2. An inextensible tension member or the character described comprising a yarn formed of spun glass, a resilient yieldable adhesive resin cement as a primer on the spun glass and a cover of vulcenized rubber bonded to the primer and forming a. protective casing for the tension member.
