DE3219086A1 - Process and apparatus for the finishing treatment of continuous textile webs and the like - Google Patents

Abstract

The invention relates to a process and an apparatus for the finishing treatment, especially bulking, compression (shoving) and improvement in feel of continuous textile webs, such as webs of woven and knitted fabric and the like, and have the object of providing a process and an apparatus for carrying out a process, by means of which fully continuous operation becomes possible. For this purpose, there is proposed, according to the invention, a process, in which the webs, after being impregnated with an effect-promoting treatment fluid and subsequently drained to a moisture content optimum for the subsequent treatment, are subjected first, in the relaxed state, to a fulling treatment and thereafter, likewise in a largely relaxed state, to one or more shoving or beating treatments, whereupon further treatments, such as washing, drying and the like, of the webs then take place. The apparatus can be designed in such a way that the shoving or beating treatments are carried out by means of beating devices, in which the cloth webs are guided past stationary beating strips and, at the same time, are shoved against the beating strips for a short time by means of rotating elastic beaters. <IMAGE>

The invention relates to a method and a device for finishing treatment, in particular for bulging, upsetting (butting) and to improve the grip of running textile webs such as fabric, Knitted webs and the like.

It is known, for example piece goods, milling and shock treatments to subjugate in order to achieve building effects on the goods and to improve their grip. Apart from this, that the known devices and systems for these purposes are complex and therefore expensive, they are only for discontinuous Operation can be used.

The present invention aims to solve the problem, • - a continuous method for bulging, upsetting and for Improved grip on running webs, especially textile webs

to create, as well as a device for carrying out the process rens.

To solve this problem, it is proposed in a method of the type mentioned at the beginning, after impregnation with an effect-promoting treatment liquid, which in particular contains lubricant, and subsequent dehydration to a moisture content that is optimal for the subsequent treatment. first of all in a relaxed state of a flexing treatment and then>'to subject one or more § shock or impact treatments, also in a relaxed state, whereupon then

that the tracks between the impregnation with subsequent Drainage and the other treatments also several consecutive ones Fulling treatments with subsequent push or Be subjected to impact treatments. The fulling treatments as well as the shock or impact treatments can be advantageous in a vapor-air mixture or in pure air at temperatures from about 25 to 60 ° C.

In the case of a device for carrying out this process, the fulling treatments are to be carried out by means of roller fulling devices, in which the webs of material are guided on trough-shaped guides lying in folds under the fulling rollers. the Guides can be trough-shaped conveyor belts in their direction of rotation, the fulling rollers to achieve this an optimal effect the conveyor belts should touch in as large an area as possible. But you can too be designed as fixed, but elastic troughs. It has proven to be useful to attach the fulling rollers to a rotating To arrange roller cage.

The shock or impact treatments should be done by means of impact devices take place in which the material webs are guided past fixed blow bars and thereby by means of circumferential elastic Bats are knocked briefly against the blow bars. To improve the effect know the blow bars provided with profiles w1o elevations or depressions be.

It has been found useful to have several striking devices to be arranged one behind the other in a vertical flow of goods from bottom to top or from top to bottom and at the point of deflection of the material webs from the ascending to the descending part of the goods guides. Several flexing devices or pushing devices combined into treatment areas Impact devices can be arranged one behind the other in the running direction of the material web through the total treatment, whereby Between the treatment areas, dwell sections are to be provided for the webs of material deposited in folds.

The treatment effects can be increased if the fulling, as well as the impact or impact devices are arranged in closed housings, in which the in a steam jet injector The generated steam-air mixture is blown in at the optimum temperature and both have an exhaust opening at the lowest point is provided.

On the basis of the accompanying drawings, the invention is intended below will be explained in more detail. In the drawings: Fig. 1 shows a fulling device arranged in a closed housing, as well as several striking devices and FIG. 2 shows a system with several areas with fulling and striking devices according to the invention,

In the device shown in FIG. 1, a flexing device is used 11 as well as several striking and jarring devices 16

The material web 10 enters the housing 22 through the opening 25 a and is about a traction mechanism 20 on a conveyor belt 12, which is guided over rollers 13 trough-shaped, in light Wrinkles applied. In the lower area of the trough, the web 10 is over a larger area of the fulling rollers 14, the are held on a circumferential cage 15, acted upon and thus subjected to a whale k process.

After the shock or impact treatment, the material web is then discharged from the housing 22 through the outlet opening 26, in which case they are then immediately subject to a subsequent further treatment or after passing through a reference bar 21 can be.
