Abstract

The invention relates to a clothing for processing textile fibers, with a clothing carrier (1) and clothing tips (2), with the clothing tips (2) being formed by wire hooks (4). The wire hooks (4) are pushed through the clothing carrier (1) in a punching process. The clothing carrier (1) is a random, paneled nonwoven formed from continuous fibers or staple fibers (10) that has been consolidated by needling and impregnated with a polymer (11) having a defined specific weight per unit area and a functional layer (12) applied to a side of the clothing carrier (1) facing toward the clothing tips (2). The polymer (1) has a proportion by weight of 20 to 70 percent of the specific weight per unit area of the random nonwoven.

Claims

1. A clothing for processing textile fibers, comprising a clothing carrier (1) and clothing tips (2), wherein the clothing tips (2) are formed by wire hooks (4) that are pushed through the clothing carrier (1) in a punching process, and wherein the clothing carrier (1) is a random, paneled nonwoven formed from continuous fibers or staple fibers (10) that has been consolidated by needling and impregnated with a polymer (11) having a defined specific weight per unit area and a functional layer (12) applied to a side of the clothing carrier (1) facing toward the clothing tips (2), characterized in that the proportion by weight of the polymer (11) to the specific weight per unit area of the impregnated random nonwoven is from 20 to 70 percent.

Description

[0031] FIG. 1 shows a schematic representation of a clothing carrier using a flexible clothing according to the prior art, and

[0032] FIG. 2 shows a schematic representation of a clothing carrier according to the invention.

[0033] FIG. 1 shows a known flexible clothing with a clothing carrier 1 with inserted wire hooks 4 that form the clothing tips 2. The clothing carrier 1 is composed of several woven textile layers 3 that are held together by binders or by vulcanization with rubber or synthetic rubber. In addition to the textile layers 3, a rubber layer is present as a covering layer 5. The wire hooks 4 pushed through the clothing carrier 1 are held in the multilayered fabric 3. During operation, the wire hooks 4 are subjected to great stress and are therefore anchored in the multilayered clothing carrier 1. Flexible clothings as well as semirigid clothings are usually manufactured in strips having a defined width b and thickness d and then placed into so-called covers or drawn up onto rollers.

[0034] FIG. 2 shows a schematic view of an embodiment of the clothing according to the invention. In the illustration, the clothing carrier 1 has a single layer with a functional layer 12. The clothing carrier 1 is a paneled random nonwoven made of PES or PA fibers 10. The paneled random nonwoven is consolidated by needling and brought to a defined thickness by the first calendering step. Through the subsequent impregnation of the clothing carrier 1, a polymer 11 is introduced into the clothing carrier 1. Through a final second calendering step, the thickness d is reached. A functional layer 12 is applied over the entire width b by means of lamination with a PUR film to the upper side of the clothing carrier 1 facing toward the clothing tips 2. The upper side corresponds to the side on which the wire hooks 4 project outward and form the clothing tips 2. The applied functional layer 12 serves not only to improve the surface characteristics of the clothing carrier 1 so that the adhesion of dust and contaminants can be reduced, but also to improve the permanent elastic characteristics of the clothing carrier 1.

[0035] Clothing carriers 1 are generally manufactured as continuous webs having a defined web length and a web width corresponding to the later length of the clothing strips and are equipped by means of the punching process with wire hooks 4 to form the clothing tips 2. After the entire manufacturing process is concluded, the clothing carriers 1 equipped with wire hooks 4 are cut transversely to the longitudinal direction of the web into ready-to-use clothing strips having the width b. In that case, the width b is between 15 mm and 150 mm, depending on the intended use.
