8 Claims. 01. 28-721) provide a novel the following detailed description and claims.
According to this invention, there is formed a batting of staple fibers. Thereafter, the batting is needled mechanically to interlock the fibers with one another. This operation consists of plunging a bank of barbed needles into the batting as it passes under the needles. The
needled batting is then treated with a bonding agent further to interlock the said fibers with one another. There is obtained in this manner a product having an unusually high strength, durability, and resilience. This batting is suitable for permanent flexible insulation, shock padding,
I filtration, and in general uses requiring a durable, bonded batting.
In forming the batting, there may be employed staple fibers of any suitable type, for example, cotton, rayon, nylon,polyacrylonitrile, linear polyesters, polyurethanes,
glass, and polyaminotriazoles. Valuable results are ob-- tained when there are employed for this purpose staple fibers of lower aliphatic acid esters of cellulose such as, for example, cellulose acetate, cellulose propionate, cellulose butyrate, cellulose acetate propionate and cellulose acetate butyrate. These staple fibers have the common property of being incapable of felting by conventional techniques.
The staple fibers may range in length from 0.5 to 4 inches and may have a denier per filament of between 1 and 75. Advantageously, the staple fibers, should becrimped and should have between 2 and 15 crimps per inch, with the fibers of higher denier having fewer crimps per inch. The staple fibers may be converted into a batting in any suitable manner, for example, by means of a batting card or the like. Another wayin which the batting may be formed is hysuspending the staple fibers 1.1113. streamof fluid such as air or water, and depositing said fibers from the strearn onto a suitable supporting structure, for example, a foraminous member through "which the stream can flow. The batting should have a thickness of at least & inch or, preferably, between 1 and 3 inches. The Weight of the batting if cellulose acetate staple fibers are used, should be at least 1 ounce per square yard or, preferably, between 2 and 14 ounces per square yard.
The batting is then passed through a needle loom where it is needled by means of a reciprocating board carrying a plurality of barbed needles- As the batting passes through the loom, the board'is moved to force the needles perpendicularly through the batting thereby driving a portion of the fibers through thebatting perpendicutates Patent Patented Apr. 11, 1961 lar to the remaining fibers. This produces an interlocking etiect, strengthening the bonds between the staple fibers in the batting. Best results are obtained when the needling is carried out so as to drive between 10,000 and 200,000 needles through eachsquare yard of the batting.
The needled batting is then treated with a bonding agent which will produce a bond between the staple fibers at their points of contact. Examples of suitable bonding agents that can be used for this purpose are polyvinyl acetate, nitrile rubber, polyvinyl chloride, polyesters, and others, as water emulsions or solvent solutions. Valuable results are obtained, particularly when there are employed lower aliphatic acid ester of cellulose staple fibers; when the bonding agent is a polyvinyl ester resin such as polyvinyl acetate. The bonding agent may be applied to the batting in solution, or as an emulsion in a liquid that is inert to the staple fibers, by spraying, dipping, or the like. The amount of bonding agent, as solids remaining in the final product, should range between 2 and 75% by weight based on the weight of the finished batting. When the amount of bonding agent lies within this range, the batting obtained will be strong, but will have an open, porous, springy structure. Following the application of the solution or emulsion of the bonding agent to the batting, the batting is dried in any desired manner, for example, through the use of heated air to drive off the solvent.
The following examples are given to illustrate this invention further.
Example I passed to an immersion saturator where it is impregnated with an aqueous emulsion of polyvinyl acetate having a solids content of 27.5% by weight. As it leaves the saturator, the batting is passed between a pair of squeeze up on rolls. The batting is drafted down at the saturator to a weight of 5.5 ounces per square yard and picks up sufficient polyvinyl acetate to give a final weight of 7.0 ounces per square yard.
Example 11 A batting having a weight of 8.5 ounces .per square yard is made by air flotation on a moving metal mesh screen from dull cellulose acetate staple fibers 2.5 inches long, having a denier of 35 and 2 crimps per inch. This batting is passed through a needle loom as described in 1 Example I at such a rate that the batting receives 97,000 needle punches per square yard. The needled batting is then passed to an. immersion saturator where it is impregnated with an aqueous emulsion containing:
Parts by weight 'Nitrile' rubber (Hycar 1571) n 100.0 Zinc oxide V 5.0 Sulfur 2.0 Butyl zincate a 2.0 Wetting agent (Triton X-200) 6.0
together with sufiicient water to bring the solids content to 25% by weight. As it leaves the saturator, the batting is passed between a pair of squeeze rolls which are set to give a 113% by weight wet pickup. The wet batting is then passed through the two zone drier described in Example I, being dried in the first zone for 1.7 minutes with air having a temperature of 107 C. and in the sec end zone for 1.7 minutes with air havng a temperature of 175 C. The batting is drafted down at the saturator to a weight of 7.3 ounces per square yard and picks up sufiicient bonding agent to give a final weight of 9.4 ounces per square yard.
Example III Polyvinyl acetate Nitrile rubber (Chemigum Latex CHS 235) 18.3 Water 75.0
following which it is passed between squeeze rolls and dried. The batting is drafted down at the saturator to a weight of 5.5 ounces per square yard and picks up sutficient bonding agent to give a final weight of 6.3 ounces per square yard.
