Process for reducing the fulling ability of wool

It was nicely proposed to reduce the fulling ability of wool by treating "oll or ¹ Xe fabric _f which consists wholly or partly of wool with gaseous chlorine or -" rom "Such a process, especially as in the British patent specification for. 417 719 has shown it to be successful in economic terms.

Each Phillips (. J. i> oc · Dy · V / oil 1942, 58 246) reacts gaseous chlorine ^ i; f .it euehter Tfolle or even ie with air-dry .vol too fast that the reaction be conducted according wünsch and that, in order to obtain economically satisfactory results in the process according to the description of British patent specification 417,719, it is essential that the scrap material of the treated oil not exceed $ 10

is when it is subjected to the 'action of the chlorine gas. This process also requires the use of expensive factory equipment, the material can only be worked on at the same time in relatively small batches, and the processing of each batch takes about an hour. It has now been found that the reaction between gaseous chlorine or bromine and wool containing more than 10 % waste material can be regulated in such a way that economically satisfactory results can be achieved in uninterrupted work and in a short time, without the need for a complicated apparatus .

The Yeriahren for treating ftollfasern to reduce their "alkfähigkeit according to t he present invention is the / composed of the fibers or they au lead-containing material in a predetermined mass continuously through nine Eammer, the atmosphere may be at room temperature and ordinary atmospheric pressure while a gaseous "halogen, for. example, chlorine or bromine gas, ie in-predetermined mass in .geleitet £ 'Ksmmer and Lacking x / ampf is withdrawn from it.

The "ass of the passage of the material and the Sass the Zufuiir of the gas are so eregelt., That each fiber of the atmosphere actual exposed in the 'Tammer during a predetermined ZeitabscLnitt, The ^ eit is measured depending nachder particular nature of the material, and The measure of the ases introduced during this period will be taken into account of the amount or weight and nature of the during this period

predetermined by that Kaniapr migratory material.

In other Viortens dimension _S in which the material d, runs .rch the chamber is controlled by (a) the physical., Tructure of titerials ^ _f (b) Oifem total Feuchtigiieitsgehalt and (c) (Ter length of ^ eges of Material through the chamber "The amount of chlorine or bromine gas to be used depends on the weight of the silicon material and its potential fulling or matting. The degree to which the chlorine or bromine gas is sent into the chamber depends on the Maas, ic it which the wool runs through the chamber.

The invention is explained by the following exemplary embodiment: The treatment was ίϋχ woven wool product, which consists of double, dyed wool yarn single warp, dyed, spun, diced wool • Weft, so-called tartan -13? 25 $ TotalfeuchtigKeitB existed and its potential walkman or YerfiIzungsfähigjieit u; it determines the ^ measuring apparatus S ', i n_Bereieh of $ 26 was?. This apparatus for checking the felting properties of textile fibers consists essentially of a talc or rubbing device with a trough which contains the aser material and a hammer for tamping the fabric (cf. British patent 571 795).

This product was passed in open-width pieces through a chamber of 366 m in an amount of 5350 g in the minute along such a sweep that every part of the fabric was in contact with the diamond atmosphere for thirty-five minutes. The chamber was supplied with chlorine gas at a rate of 90.70 g per minute and an exhaust fan removed the exhaust

fumes. The movement of the tissue through the chamber and the action of the exhaust fan ensured proper contact between the tissue and the chlorine gas. Bie Asmer was at room temperature and atmosphere quickly. After the tissue from the ^Xk on "- r ^; m, it was treated with an antichloro and then finished as usual. The potential 'alkaline enema of the treated tissue, when measured according to the method described above, was in the range of 0 50 -ed An examination of the treated Uewebes after Kiton •. ^ ^x.
