Definitions

• This invention relates to an improved process in connection with the manufacture and production of threads, filaments, bands and the like consisting of cellulose or a compound of cellulose, and containing in addition thereto one or more finely divided liquid or solid bodies which are more or less evenly distributed in the cellulose or cellulose compound.
• threads, filaments, bands and the like consisting of cellulose or a compound of'cellulose and containing in addition thereto one or more finely divided liquid or solid bodies which are more or less evenly distributed in the cellulose or cellulose compound, may be obtained in an excellent manner by first filtering and removing the air from the viscose or other spinning solution, then adding the liquid or solid body and mixing the whole completely or sufliciently while avoiding any introduc-' tion of air into the said solution, and finally passing the mixture thus obtained to the spinning machine, where it is converted into threads, filaments, or the like.
• Example The oil may be placed in a vessel under pressure caused by compressed air, and allowed to pass from the containing vessel through a feed pump, which delivers the desired quantity of oil per unit of time, and which may for instance be similar. to the pumps which are employed for feeding the viscose to the spinnerets of a. spinning ma chine.
• the oil thus supplied by the feed pump passes along a pipe which joins with the pipe which supplies viscose for a number of spinnerets, and the mixture of viscose and oil thus obtained passes through a series of finely perforated plates, and then into a vessel, which may consist of a widening made in the pipe, and which contains a.
• the mixture may be submitted to a further mixing operation shortly before it reaches the spinnerets, it being understood that such further mixing the leuco vat colouring matter may be added in the form of an alkaline solution, the feed pump for the said solution and the mixing apparatus being arranged in a manner similar to that-already described the rate of supply by the feed pump being regulated according to the depth of colour desired in the finished thread.
• solid bodies which may be added according to this invention may be mentioned carbon black and china clay, which are particularly suitable for incorporation in coarser filaments, such as monofil, the said solidibody being first mixed with a liquid, whereupon the mixture is freed from air and then fed to the spinning solution as already described.
• the body whether insoluble or soluble which it is desired to add, may be mixed with a small quantity of the spinning solution so as to make a more or less concentrated solution or suspension of the said body in the said spinning solution, which is subsequently added at a measured rate, if necessary after filtration and removal of air, to the main body of the spinning solution which main body has already been filtered and freed from air.
• the process according to th present invention includes the addition to the spinning solution of a body which during the spinning and/or subsequent operations becomes convertedinto the body which it is desired shall be contained in the finished threads", filaments, bands and the like.
• the addition to viscose of a leuco vat colouring matter which ,dur-: ing spinning and/0r subsequent operations, is converted into the vat colouring matter itself as already referred to.
• a process comprising the following steps: first filtering and removing the air from the spinning solution, then passing the filtered and de-areated spinning solution towards the spinning machine, and during this passage, while the spinning solution is no longer in bulk, adding the pctroleum oil or petroleum jelly and mixing the same while avoiding any introduction of air into the said solution, and passing the mixture thus obtained to the spinning machine.
• filaments, bands and the like consisting of cellulose or a compound of cellulose, and containing in addition thereto a finely divided li uid more or less evenl distruffed which the said addition can exercise its ageq y l in the cellulose or cellulose compound, a process COIIII rising the following steps: first filtering and'removing the air from the spinning solution,.then passing the filtered and de-aerated spinning solution towards the spinning machine, and during this passage,
