DE1917848B2 - Process for the production of a non-woven textile web - Google Patents

Description

The invention relates to a method of manufacture a non-woven textile web made of at least two superimposed layers of yarn or Strands of thread, with the strands of one layer crossing those of the other and the two layers are tied together while all of the strands are held clamped at the edges of the web.

Such a method is known from British patent specification 1,042,134. The connection of the two superimposed layers is done there by gluing, namely under application by adhesives, or with the application of heat and / or pressure. However, this has the disadvantage that the product made by this process because of the sticking together of the two layers is relatively stiff.

DT-AS 1 059 393 shows a method for producing a non-woven textile web from at least two superimposed layers of yarn or thread strands, with the strands one Layer crossing those of the other. The connection of the two strands is also made here by gluing, so that the stated disadvantages are also present. -1 ·· - . ·

From the book "Textilverbundstoffe", Leipzig 1963, p. 139 ff, it is known, fleeces under a needle board to lead through. The needled fleece produced in this way is used in particular for upholstery fillings, Underlays "for mattresses" and carpets, for Horse blankets and used for saddle felts. So there should essentially be three-dimensional objects getting produced.

The invention is based on the object of a method with the features mentioned at the beginning to propose, with which non-woven textile webs are produced, which are characterized by a very versatile Distinguish applicability. In particular, the textile web should be relatively soft and flexible in its plane be it; sd that i use them, among other things, to manufacture can be used by clothing.

The solution given at the beginning is used to solve this problem A method characterized in that the connection by mechanical penetration of the Strands, e.g. B. by needling.

Without additional material consumption, such as glue, additional yarn or the like the invention a sufficient connection

By "cable" a similar invention is to be understood as meaning that a yarn or material in which the bundle of fiber cables is used, which is connected to another of the endless threads, which are usually practically either yarn and / or cable are spirally wound, weigh more than 5000 denier, or are twisted. Apply the needled fabric obtained. A cable therefore differs from a good grip and thread, regardless of its weight, by the total denier, whereby denier case. For example, two strands of modacrylic were used, the weight in grams of 9,000 meters of fiber material, each of which means a total weight of 180,000 denier. There is no particular denier, 60 possessed, one of which distinguishes a weight of 3 denier per the yarn of tow, and the non-monofilament and the other a weight of 40 Deterscheidwig criterion of 5000 denier is for one per monofilament, together twisted arbitrarily in the case of an approximately fan-out representation of the invention.

In this turned-over denier per thread of more than about 8 typi-part, the dark and shearly an open-meshed fabric used in the fabric are visible, while light-colored tow strands (145 or 146) are visible. The> 5 twisted fibers with a denier below about 8, have needling on the front side in FIG. 14 preferably about 3.5, in particular less than about 2, causes different effects. If, for example, light colors, such as between approximately 1 to approximately 2 denier per Fa tow cord 146, intersect with light tow cords 146, result in a dense fabric. Based on the zen, needling provides a completely bright raised surface that, when a darker Wergstrang crosses through the use of surface 141. 145 io fibers of the same weight with lower denier with a dark Wergfadenstrang 145 corresponds is obtained. Since the yarn is untwisted, there can be a completely dark spot 144. If a single fiber or thread spreads out over the open, dark tow 145 a light tow 146 areas of the fleece and crosses a good, dense one, the needling creates a mixed- Forming tissue. The fabric can then be pressed with thermoplastic panel 143, in which light fibers are pressed into the predominant, thermosetting resins or latex rubber-looking dark fibers. Treated in a similar way and hardened on a calender, the needling produces a mixed-colored so that a fabric with a smooth surface and the square 142, in which the dark fibers are obtained in a pre-appearance of fine cloth,

In carrying out the invention, one must become. If two individual layers of cross-connection between the tow or yarn wire system of endless threads or staple fibers and the denier size per thread are needled according to the invention, you should choose (or, in general, the cross-section ”- 95 rend them the sides are attached, you get a diameter of the fiber). In the production of a non-woven material with considerable stretchable fleece from crossed, non-twisted Werg speed in the transverse direction to the crosswise laid or yarn made of endless threads or staple fibers and strands of yarn. This stretchability is comparable to needles according to the invention, the fibers or with the stretchability customary in woven fabrics. Threads are spread over the entire surface by needling. This principle is shown in FIG. 9, in which pelted or air-laid staple fibers or, however, the open spaces for explanation of solidified, unaligned, endless threads would be greatly exaggerated of the untwisted fiber cable structure - no equivalent elasticity after needling are shown. F i g. 14 shows structures resulting in a nonwoven fabric,

The degree of expansion depends on the achievable stretching or stretching properties little of the amount of fibers present in an area are at least partially obtained by the fact that fibers of larger strands held in the same or similar rows in the or threads, depending on the spacing of adjacent tissue - cutting length than are laid in garnetted, carded or tongued, and of the frequency and thickness 40 air-laid piles are included.

If the needle treatment is too strong, the material is held against a strong light source so that so many fibers are broken and shortened that it looks completely uniform, without the stretching properties that are characteristic of an unsavory structure, the dark characteristics of a uniform product and needle treatment in the usual way, bright spots. If, however, the strands are consolidated by twisting, carded or air-laid piles, then a spreading out of them will be released. In order to achieve a stretchable product, fibers that can be stretched are prevented, irrespective of the size of the needle, according to the invention.

Claims (1)

ϊ 917 Claims: ~ 1. A method for producing a non-woven textile web from at least two superimposed layers of yarn or thread strands, the strands of one layer crossing those of the other and the two layers being connected to one another, while all strands are held clamped at the edges of the web , dasdureh ■ marked that the connection is made by mechanically penetrating the strands, for example by needling "- v» r '■■ - ■■■ · · 2. Procedure according to. Claim 1. characterized in that in addition to the shortened layers at least one wide * -Schicbt.Yon yarn or thread strands on at least "one side of the crossed layers is clamped, whereupon at least some strands of the additional layer with at least some strands of the crossed layers mechanically penetrated. 3. The method according to any one of claims 1 or 2, characterized in that in addition to at least two first layers in which the strands are at a first included angle cross, at least two further layers are provided in a predetermined pattern, the threads of one further layer being those of the other layer to form a -second ·, different from the first included angle, second included angle when clamped The web edges cross, whereupon at least some of the strands of the first layers come together mechanically interspersed with at least some of the strands of the additional layers with at least two of the strands of the additional layers in the restrained condition are mechanically interspersed and linked with one another. 4.
