How to make needle felt and decorative pattern nonwoven fabric

FIELD OF THE INVENTION The present invention relates to a method for producing a needle-felt and decorative patterned nonwoven fabric, wherein all or part of the surface of the monochromatic pre-needle felt nonwoven web (web) is desired to be decorated in whole or in part. The nonwoven fabric, which is then a patterned nonwoven fabric, is placed in a dry state with no interlaced fiber zones on top of two different pre-needle felt nonwoven webs of two different colors, and then the two joined webs are needle felt each other.

In this type of known method (German Patent No. 1901755, UK Patent 1267764), the fibers of a nonwoven web serving as a patterned nonwoven web are interlaced using a glue or a binder and the two differently knitted webs of different colors are contrasted with each other. Fold and needle needle together from the stalemate side. According to this method, instead of using one pattern-forming nonwoven fabric partially interlaced according to the pattern, a combination of decorative patterns having several primary (primary) colors by using several partially interlaced pattern-forming nonwoven fabrics with strange colors. Can be prepared.

In this conventional method, the non-woven cloth of the interlaced nonwoven fabric was needle-felt into a fabric bonded to form a pattern and the pattern was formed on the exposed (non-laid) surface of the bonding fabric. On the surface, a pile formed by non-bonded fibers appears to be completely formed, while in the interlaced portion, the glued nonwoven fabric is only needle felt with the fabric bonded to form a pattern thereon.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for producing a needle felt and decorative patterned nonwoven fabric, in which the bonding between the various nonwoven fabrics at the deadlocked part is sufficiently observed while the effect of the pattern is improved.

Therefore, the method of the present invention is characterized by a method of needle felting two nonwovens from the second nonwoven side to form a pile surface on the exposed surface of the first nonwoven fabric serving as a pattern forming nonwoven fabric. In the conventional method, the needle felt from the nonwoven web containing the interlaced fiber, but in the method according to the present invention, the needle felt from another nonwoven fabric having no interlaced fiber area at all. Deadlocking of fibers can be achieved by using glue or binder, or by melting the fibers to an appropriate strength.

The advantage of the method of the present invention is that the fibers of the second nonwoven fabric without the interlocking portion completely penetrate the intersecting portion of the nonwoven pattern forming fabric and form a pile while connecting the headwoven fabric, so that both webs are completely maintained while maintaining the pattern effect. Mechanically strong at the site. The piezoelectric mechanical coupling effect of this system results in the formation of piles on the opposite side of the non-woven nonwoven web by needle felting several different colored decorative interwoven nonwoven webs again from the other monochromatic nonwoven web side. Also obtained is obtained. In this case, complete fiber connection is made at each site of the pile-forming needle felt multilayer system, while a multicolor effect is obtained on the pile layer formed.

Partially in accordance with the method described in German Patent 1901753, three pre-needle felt nonwoven fabrics of three primary colors, blue and yellow, interlaced to suit the desired pattern, are added to the three primary colors to add mixed colors of rust, purple and brown. I found out that it can be made. Its suppression can be achieved by adjusting the color depth of the three primary colors (lightness in a suitable way) and / or by appropriately selecting the thicknesses per square meter between the webs, for example, if the denits of each web are the same, This is possible when the desired secondary color (mixed color) is produced by the amount ratio between the different color fibers in the pile determined.

The fourth non-woven nonwoven web, when made as a colorless, for example, white fiber, serves not only to completely bond the three interwoven interwovens of the three primary colors as described above, but also to be suitable for all multicolored patterns appearing in the pile layer. You can give the brightness of (明度). The effect of brightening this color is a function of the thickness, i.e. the weight of the non-bonding web and the number of denite selected. It should also be noted that partially glued the fourth white or colorless nonwoven web completely loses the brightness effect in the glued portion. By changing the depth of penetration of the partial deadlock, the color brightness can be adjusted in several stages.

On the other hand, if desired, pure white patterns can be made by completely interlocking red, blue, and yellow subwoven fabrics in the non-deadlocked positions of the fourth white nonwoven fabric to form piles here by only the white fibers of the fourth nonwoven fabric. In all cases, even though each layer is partially interlaced to some extent, such a multilayer system combines the whole system very well. In addition, even if the layer members are interlaced differently, only the fibers which are not bonded by glue at a certain time in the pile depth are fed into the pile, so that the pile is very uniform in the net web system. .

The above method employing red, blue, yellow and colorless four-woven webs makes it very simple to produce decorative multicolored patterns that include virtually any color. From this, the only significant benefit is that the three primary and primary white fibers of blue, red, and sulfur can be secured to produce any other desired color and hue with these three primary and primary white fibers.

In this regard, the mixed colors formed in the pile have a characteristic that looks brilliant because the primary colors remain adjacent to each other in the pile, and the colors are combined in a very special way to deliver the desired color to the naked eye.

Thus, using needle felt technology, a strong color mixture (mixing color) can be obtained which cannot be obtained simply by mixing in the fibers.

This method is particularly critical when dealing with fibers that are not all-dyed or hardly dyed in the form of fibers or which must be printed one by one. This is particularly true of polypropylene fibers which are preferably treated in the form of undiluted salts.

The following describes in detail typical applications of the present invention. Polypropylene tapered fiber, 17 detex thick, 80 mm long, or 430 cm, weight per square meter (a) 250 g (b) 200 g, (c) 150 g ), (b) and (c) are made without blisters. In addition, a 90mm-long polyamide blended fiber consisting of 50% of 40-degree thick and 50% of 17-degree thick is made of a primary white nonwoven fabric (d) having a weight of 200 g per square meter. The colors of the nonwoven fabrics (a), (b) and (c) are all undiluted half yellow (a), mid red (b), and mid blue (c).

Non-woven webs (a), (b) by superimposing the three nonwovens in the above manner in response to the required pattern and the desired color, so that the color or colors of the non-bonded areas create a pattern which will produce a pattern effect if the needle is felt later. ) and (c) are partially interlaced with the binder by cylinder-printing.

After partially interlacing the three nonwoven webs as described above, the fabrics are overlapped and passed through a tunnel dryer to completely dry the glass binder. Combine the three nonwovens (a), (b) and (c) with the primary white nonwovens (d) after the drying process is completed or before they are put into the dryer. After that, with two fork-shaped needles to run, the needle penetrating 'depth is 10mm and needle felt to form a pile.

The fused material made of the four nonwoven webs by implantation is reinforced not only mechanically but also by impregnated (attached) binders, but by slop padding or latex dispersion, by doctor finishing. In addition, it can be reinforced evenly in all directions by back dipping (침 面 沈 漬).

The carpet (carpet) made by the above-described method has a texture in which a vivid decorative multicolored pattern is finely embroidered, and the pile surface has a uniform density over the entire width of the carpet. The carpet pattern shows the shades of blue, red, yellow, green, purple, brown, white and its color in the desired place, by using a grid of different densities (dotted lines) on the crimping cylinder. It can be achieved by differentiating the partial deadlock strengths of the sites, respectively.

Again, the whole color depth of all colors can be adjusted by totally or partially interlacing the primary white nonwoven web (d) to a different degree. It is also possible to vary the local deadlock strength of the nonwoven web (d) by using different densities of grit on the principal surface of the press cylinder. In all cases, the deadlock process is similar to the conventional printing process, except that the colorant is replaced with a binder or glue.
