摘要:
The invention relates to a process for the continuous dyeing of textile webs of synthetic fibres or mostly synthetic fibre materials with suitable dyestuffs and dyestuff fixation according to a usual method, wherein the padding operation of the fibrous material with an aqueous dyebath having a relatively high concentration and squeezing off the excess of liquid is effected while pressing from both sides endless webs of an absorbent fibre material (auxiliary webs) onto the material to be dyed.

Process for the continuous dyeing and printing of piece goods made of synthetic polyamide fibers, preferably blended with cellulosic fibers, using reactive dyestuffs according to a thermofixing method, by applying onto the textile material an aqueous padding liquor or a printing paste, which has been weakly acidified by means of a buffer system of acetic acid and an alkali metal acetate and which contains a fiber-reactive dyestuff whose reactive groups have reversibly been masked by reaction with an alkali metal salt of an N-alkyl-aminoalkyl-sulfonic acid, and after drying of the material fixing the dyestuff on the two fiber components by means of dry heat.

The invention relates to a vehicle body structure in the floor region of the occupant compartment having on both sides a respective longitudinal beam (3) in the floor region of the occupant compartment between a transmission tunnel and a side sill. According to the invention each longitudinal beam (3) extends longitudinally continuously over the entire footwell length from the front end (4) to a heel plate. The longitudinal beam (3) is here formed on the bottom side as a closed longitudinal hollow beam by virtue of a longitudinal beam stepped edge (9) of the floor panel (10AB) and on the top side as a longitudinal beam closure part (11SW) by virtue of a longitudinal beam angle section connected to the top side.
摘要:
Hitherto there has been no practical pad-dwell process for wool piece goods which could be carried out without using large amounts of textile assistants. In addition, it has been necessary with all these processes to supply energy. Furthermore, large amounts of urea have always been used, which inevitably resulted in a high degree of waste water pollution. It has now been recognized according to the invention that satisfactory results can be obtained in the dyeing of wool piece goods with reactive dyes by effecting the padding operation with the dye solutions within the pH range from 1.5 to 4 and at room temperature and the subsequent dwell operation to obtain dye fixation without supply of heat. To prevent the formation of a frosting effect and to obtain deeper shades it is expediently possible also to add to the padding liquor nitrogen-containing ethoxylation products, in particular ethoxylated fatty amines, and/or alkyl polyglycol ethers.
摘要:
A process for the dyeing of textiles which consist totally or partially of cellulose fibers, with reactive dyes according to the batchwise exhaustion method, which comprises using aqueous dye liquors containing one or several reactive dyes as well as at least one neutral electrolyte, the initial pH values of said liquors being in the slightly acid range, in the high temperature range at 110.degree. to 140.degree. C. without the addition of an alkali or alkali-yielding agents.

摘要:
In a method and apparatus for producing a composite component comprising a hollow profile and at least one injection-molded element, a hollow profile (3) is formed by means of internal high pressure fluid forming and is encapsulated with an injection molding material to form the injection-molded element. The hollow profile is expanded by means of internal high pressure in a closed combination tool comprising an internal high pressure forming tool element and an injection molding tool element, before it is encapsulated. The hollow profile is pressed on the tool engraving only locally in the region of the location to be encapsulated, keeping the outlet of the injection molding channel opening into the tool engraving clear.
摘要:
A motor-vehicle front end having a front bumper and a front covering which is mounted behind it, the front covering being mounted pivotably on a load-bearing structural member and in a frontal impact being pivoted rearwards about an approximately horizontal vehicle transverse axis by being carried along by the bumper by the rearwards displacement of an associated region of the bumper, a support being provided between a rear supporting surface of the bumper and a mating surface of the front covering for the purpose of carrying along the said front covering. In order to be able to reduce the space required for the arrangement in the motor-vehicle front end without incurring losses in its functioning, the front covering is suspended in a pendulous manner on the load-bearing structural member at a distance above the bumper and in its lower region is fastened permanently to the supporting surface of the bumper by the mating surface.
摘要:
Semi-continuous process for dyeing of flat woolen textile articles with 1:2 or 1:1 metal complex dyestuffs, by padding the textile material with an aqueous liquor containing the dissolved dyestuffs and of from 80 to 120 g/l of dissolved urea, at a temperature of from 60 to 80.degree. C. and batching it up without intermediate drying, optionally with further heating, and allowing it to dwell in this state at a temperature of from 75 to 85.degree. C. for a period of from 4 to 14 hours.
