Problems solved by technology

However, if one compares tear strength, pilling, and firstly washability, especially in boiling water, with conventional fabrics, it turns out that such sheets are weak
First, depending on the use characteristics of microfibers deteriorate significantly over time

[0137] Example 13: Detection of different parameters of nonwoven fabrics

[0138] Detection is based on the following criteria:

[0139]

[0140]

[0141] The results of the tests are shown in the table below:

[0142] Textile physical analysis processing:

[0143]

[0144]

[0145] When analyzing the results of Table 3 it was first found that in all samples which consisted entirely of Pie-32 or of Pie-32 located on the outside, a particularly high washing resistance was recorded on the outside. This is as surprising as it is unpredictable: thin filaments show good mechanical stability. However, towels composed entirely of Pie-32 are only of limited durability, since towels have a much lower tear strength in the first place. In contrast, the composite nonwovens according to the invention are distinguished not only by satisfactory tear strength and maximum tensile strength, but also by good washing resistance. Furthermore, it can be seen from the table that, sur...

[0153] Example 16: Visual inspection of nonwoven fabrics

[0154] exist Figures 2 to 6 Photographs of exemplary nonwoven fabric surfaces are shown in .

[0155] exist figure 2 shows the surface structure of nonwoven fabric No. 2 not according to the invention after 250 washing cycles. This shows that the surface is very rough and has a high pilling score.

[0156] exist image 3 shows the surface structure of nonwoven fabric No. 1 not according to the invention after 250 washing cycles. The surface, while having an improved profile compared to No. 2, was rough throughout and had a high pilling score.

[0157] exist Figure 4 shows the surface structure of nonwoven fabric No. 3 not according to the invention after 250 washing cycles. The surface has a much improved profile compared to Nonwoven No. 2. As already mentioned above, a nonwoven consisting entirely of patty-32 is only limitedly durable, since it above all has too low a tear strength.

Abstract

The invention relates to a microfiber nonwoven composite, comprising a first and a second fiber component arranged in form of alternating layers, wherein at least a first layer A comprises the first fiber component in form of composite filaments melt-spun and deposited as a nonwoven fabric which are at least partially slit and solidified to form elementary filaments having an average titer of less than 0.1 dtex, preferably between 0.03 dtex and 0.06 dtex, at least one layer B is arranged over layer A, wherein the layer B comprises the second fiber component in form of fibers deposited and solidified as a nonwoven fabric having an average titer of from 0.1 to 3 dtex, and at least one second layer A is arranged on layer B.

Description

field of invention [0001] The textile physical properties of a web product can be controlled by the chemical and textile physical properties of the fibers or filaments forming the web product. In this case, the fiber raw material or filament raw material is selected according to the desired chemical or physical properties, for example its dyeability, chemical resistance, its thermoplasticity, its dirt-holding capacity or absorbency. The modulus and force-extensibility properties of fibers or filaments also depend on material properties that can be controlled by selecting the degree of crystallinity and / or orientation and cross-sectional geometry in order to affect the bending stiffness, force-absorbent or specific surfaces. The textile physical properties of the fibers or filaments forming the textile sheet are also controlled by surface weight. [0002] For various application purposes, textile webs must be adapted to various requirements, which are often difficult to harmo...
