Patent GB-347169-A (GB)
Title: Improvements in the production of nitro cellulose
IPC: C08B5/02
Filed: 1929-12-14
Abstract: According to Specification 323,019, [Class 2 (ii), Cellulose &c.], wood pulp is partially gelatinized by treatment with caustic soda and carbon bisulphide, immersed in the form of strings or pellets in a hardening solution, washed, dried, and nitrated with a mixture in which normally the nitric acid exceeds the sulphuric acid.  This method is now modified by nitrating the hardened and washed strings or pellets while they still contain a considerable amount of water, e.g. 10-20 per cent.  A nitrating mixture containing less nitric acid than is recommended in the prior Specification, and in some instances an ordinary nitrating mixture, may then be used.  The final washing of the hardened strings or pellets may be effected with warm water at a temperature of 50-70 DEG  C. or with nitric acid.  The material may be centrifuged before nitration.  In an example, wood pulp is partially gelatinized by treatment with 10 per cent of caustic soda and 5 per cent of carbon bisulphide; if the wood pulp is preliminarily ground, 5-7 per cent of caustic soda and 2-3 per cent of carbon bisulphide may suffice.  The product is then formed into strings or pellets, hardened in a bath containing 2 per cent of sulphurous acid, and washed, the final wash water being warmed. The product is then nitrated, while still containing 20 per cent of water, with a mixture containing nitric acid 37, sulphuric acid 57, and water 6 per cent.

Title: Method for producing a rearranged fabric having cross strength
IPC: D04H1/70
Filed: 1972-08-18
Abstract: 1371863 Rearranged fibrous web; stretching fabric JOHNSON & JOHNSON 18 Aug 1972 [20 Aug 1971] 38658/72 Headings D1R D1S and D2B The fibres of a web are rearranged into areas of greater and lesser or even zero density, the web is then stretched transversely and the fibres then subject to a second rearrangement. The rearrangements are accomplished by known apparatus e.g. as shown by passing web 13 supported upon a belt 11 having 900 to 50,000 openings/sq in around a drum 10 having uniform openings of 1/32 in diameter through which issues water supplied by banks of nozzles 12. A mechanical rearranging means (D, Figure 4, not shown) comprises a rotating cylinder (56) having on its outer surface a plurality of needles (57). The web is moisted by a pair of wet-out rolls, pressed into contact with cylinder 56 by a reciprocating brush (60) and rearranged under the combined action of needles (57) and the soft bristles of rotary brushes (65-68) adjacent the surface of cylinder (56). A third rearranging means (F, Fig. 4, not shown) comprises a plurality of nozzles which spray water onto the web whilst it is supported by a foraminous endless belt which runs over a suction box. Different apparatus may be used for the two rearranging steps. The web is preferably transversely stretched uniformly across its width by 50 to 150% of its original width. As shown the spreader B comprises extensible coil springs 30 secured between disks 31, 32 disposed at an angle to each other. Alternatively the web may be spread by a tenter frame (Fig. 5, not shown) or a bow spreader. The transverse spreading produces a longitudinal contraction of up to 35%. The web may be air laid, wet laid or carded. The process increases the cross strength and decreases the longitudinal strength of orientated carded webs. The fibres are preferably glass, cotton, flax, viscose rayon, cellulose acetate, polyamides, polyesters, acrylics, polyolefins or combinations thereof, and have a length of  inch to 2¢ inches and a denier of 1¢. The starting web may weigh 80 to 2000 grains per sq. yd. The fabric may be bonded, dyed, or coated. Thus the rearranging fluid may comprise an aqueous or non-aqueous bonding medium. Thermoplastic binder may be applied as a powder before during or after rearranging and then fused. Adhesive may be printed on the rearranged fabric. Alternatively the rearranging treatments alone may impart sufficient coherence.
