Definitions
- the present invention relates to improvements in or relating to the treatment of wool textiles for the purpose of rendering such textiles repellent to water.
- the process is based on the surprising discovery that wool is rendered to a high degree repellent to water in every stage of the working up processes, that is to say as loose wool, yarn, fabric and inthe form of knitted and woven goods whether ina raw, bleached or dyed condition, by
- thetic washing' agent perorlitreiwithi aid itienofzso much ammonia that the liquor remains neutall even after treatment of the cloth. It is'then subjected to the usual mechanical finishing proceu.
- the material is eminently suitable for rain-coats.
- the usual textile soaps such for example as the shredded potash soaps-used for fulling or the like, may be used'for the process according to the invention; but it has been found to be advantageous to use such soaps as do not have an unpleasant smell. Not) onlyls it relatively difficult to remove such a smell from the goods, but moreover some of odoriferous substances, es
- the concentration may be varied but, in order'to obtain good results, not less than 0.5 gram per litre and for practical purposes not more than 10 grams per litre are used. If the concentration is too high; the process becomes uneconomical and inferior-results are produced. It is usual therefore to use from 1 to 4 grams per litre.
- the temperatures are held-preferably betweenand C.; in, the case of thicker ma terials' it may be advantageous'to raisethe temperature tom- C.
- the duration 'of the process has a comparatively small influence on the efiect when the temperatures are low'; it seems to be produced almost instantaneously and it is immaterial whether the treatment lasts for 5 minutes, 10 minutes, 30 minutes or an hour. At higher temperatures the efifect deteriorates if the treatment is prolonged; for instance at 50? the treatment is not continued for more than- 54' hour.
- the process can be carried out successfully in very different waysprovided that the main condition, that is. to say, the cleanliness of the material to be treated, is fulfilled.
- the mode of carryingout the process thus depends to alarge extent on the pretreatment to which the material was subjected and on whether impurities due to the pretreat ment and which can only with difilculty be washed out, adhere to the fibres or not.
- the process can most easily be carrie'dout with success on materials which have previously'been dyed in the b0 ing liquor ofan acid. bath.
- This dyeing operation involves in itself a thorough cleaning of the fibre and if is merely completed by very careful rinsing and neutralization, the treat-- ment produces the most favorable results without further diilicuity. Greater attention is necessary however if the material has finally been fulled or subjected to carbonization. In such cases the ordinary rinsing is frequently insufficient in order to free the fibre from substances which are active on the surface. In such cases it is necessary in order, for reasons of economy, to avoid a repeated treatmentof the material, to carry out the,preliminary washing with particular care, either by using soap in higher concentration and in a short liquor or' by using synthetic washing agents or alumina. The preliminary washing is always accompanied by neutralization.
- the quantity of liquor which is used for the actual treatment depends in some measure on the pretreatment .of the material.
- the liquor In the case of materials such as the last mentioned goods, or bleached goods, where small quantities of products of decomposition may adhere to the fibre despite careful preliminary washing, the liquor must in no case be too short, and in such cases the treatment-is generally carried out withl0-20 times the quantity of liquid, so that the accumulation in the liquor of any decomposition products which may stm be present does not attain too pregnation must always be carried out after'the last acid treatment, that is to say after dyeingand.aft'er.carbonizing.
- the fulling and bleaching should also preferably precede it. However all the finishing processes which are carriedout by mechanical means or steam may follow the impregnating process.
- wool in the sense of the present invention comprises, in addition to sheep wool, animal hairs of all kinds and further so called artificial or old wool.
- textiles as used in the sense of the present invention includes felt and similar materials made of wool.
