Abstract

Non-woven fabric wicks are newly prepd., which are composed of several layers of non-woven fabric in which short and long fibers are arranged parallel or randomly. One of the sides is coated with a thermal adhesive bonding fiber, such as a bicomponent fiber of nylon 66 and nylon 6, polyethylene terephthalic acid and polybuthyl tetephthalic acid, or polyethylene terephthalic acid and copolyester. The amt. of the bonding fiber is different in all layers, and the smallest ant. is contained in the interfacing layer between the inner and outer layers.

Description

Composition of nonwoven wick

TECHNICAL FIELD This invention relates to the construction of clothes | clothes or other sewn interlinings of a nonwoven fabric adhered to outer skin welfare by an adhesive agent. The wick of the present invention is composed by bonding a plurality of nonwoven fabrics, the multiple layers of the nonwoven fabric is characterized in that their respective configurations are different, and the bonding method using an adhesive or "bonder fiber (bonder fiber) (linder fiber, bonding fiber) In addition, a thermal adhesive that bonds with heat and pressure is used for bonding the wick and the skin welfare of the present invention, that is, a thermal adhesive is applied to the wick and the skin welfare is applied to the wick. I use another tool to glue them together.

The material used for the wick should be soft and stick to the body. Recently developed nonwoven fabrics are used as a wick material in the sewing industry because they are soft and stick to the body. This nonwoven fabric is made by bonding multiple layers of fibers with an adhesive, which is worn or melted during the process of using the nonwoven fabric, that is, during the "dry cleaning" process, in particular, using a material. Must have heat resistance to withstand things.

In order to reinforce the nonwoven fabric for such heat resistance, "binder fiber" is used. The "bonding fiber" is melted at a constant temperature to bond with the fibers constituting the nonwoven fabric to form a rigid structure.

However, if a lot of "bonded fibers" or other reinforcing materials are used, the nonwoven fabric becomes hard and stiff. For example, when 5 to 10% of `` adhesive fiber '' is added to a nonwoven fabric, the cloth becomes significantly stiff, while the increase in heat resistance is minimal.In order to increase the heat resistance, more `` adhesive fiber '' must be added and then the fabric Becomes stiffer. Therefore, an object of the present invention is to develop a wick made of a soft non-woven fabric (when "dry-cleaned") that is not easily worn and melted, and another object is to develop a thin and soft general welfare.

As described above, the wick of the present invention is composed of multiple layers of nonwoven fabrics, and the nonwoven fabric forming the outer layer constituting the surface on which the wick and the outer covering are bonded is different because each nonwoven fabric layer constituting the entire wick is different. It has been found in the present invention that the outer layer comprising the `` fiber '' and forming the opposite side of the wick is a surprisingly soft and heat resistant wick comprising the most `` adhesive fiber ''. Once the cotton containing "adhesive fiber" is adhered to the outer covering by adhesive, it is less likely to produce this result than the opposing layer containing a lot of "adhesive fiber". Compared with conventional nonwoven wicks, wicks with higher heat resistance to the action of chemicals through wear, washing or "dry cleaning" have been developed. Had been found to be the core according to the invention is suitable for well-being thin and soft shell, the core of the bonded non-woven fabric used in the prior art is not suitable for the well-being thin and soft.

Some nonwoven layers, ranging from 40% to 80% of the total weight of the wick, composed of multiple layers bonded to the outer sheath, are less than 30% of the total weight of the "bonded fibers" contained in the entire wick. It has been found that the outer nonwoven layer, which forms the opposite side of the wick layer to be bonded to the skin, should contain at least 30% and at least 100% of the "bonded fiber" by weight of the "bonded fiber" contained in the entire wick. . For example, if five layers of non-woven fabric are bonded to form a wick, two to four non-woven fabric layers including the wick layer bonded to the outer covering are composed of 40% to 80% of the total wick weight. Fiber "shall include less than 30%" adhesive fiber "by weight, and the remaining nonwoven layer comprising the nonwoven layer forming the other side of the wick contains at least 70% of the" adhesive fiber "of the total" adhesive fiber ". shall. However, the ratio of "adhesive fiber" to the layer bonded to the outer covering should be as low as 30% and at least as low as "bonding fiber", and the outer nonwoven layer forming the opposite side may be 30% to 30% of the total "bonded fiber". It is best to include 60% "bonded fibers." Considering the case of joining non-woven triples, the two layers of non-woven fabric and the next layer join together to form 40% to 80% of the total wick weight. In the layer, "bonded fiber" corresponding to less than 30% of the total "bonded fiber" should be used, and the layer bonded to the outer sheath may include 30% of the "bonded fiber" or the "bonded fiber". The nonwoven layer, which does not need to be included at all, and forms the other side of the nonwoven layer bonded to the outer sheath, includes 30% to 100% of the "bonded fiber" of the total "bonded fibers".

Each non-woven fabric layer is formed by short or long fibers or fine fibers such as endless fibers, randomly arranged, forming a flat line, or staggered with each other. "Bonding fiber" is used to bond the wick and the outer covering using iron or other method using the above-mentioned thermal adhesive. In this case, the thermal adhesive is applied to the core surface in advance and the whole surface is also applied. However, in some cases, it is applied only in a certain position, and the part where the thermal adhesive is applied is usually formed. When looking at the entire wick surface, the purpose of use or in some cases, several adhesive points are applied in one form. And applying a thermal adhesive on one side of the wick also constitutes the gist of the configuration of the present invention. The thermal adhesive can be applied using a conventional method similar to the method of applying printing ink to paper with a printing press.

In the process of forming a nonwoven fabric, a "binderfiber" (bonding fiber) in which part or all of itself is melted under a certain temperature and bonded to a nonwoven fabric is usually a "polyethylene terephthalic acid" artificial fiber and a "polybutylene terephthalic acid". It is preferable to use "bicomponent fibers" or other "polyethylene terephthalic acid" fibres and "copolyester" composite fibers or composites of "nylon 66" and "nylon 6". "Composite fiber" means that two or more heterogeneous fiber resins are injected through the same extrusion or injection hole in the process of forming the fiber by extruding or injecting the artificial fiber resin so that a kind of resin is formed in the center of the fiber. In the outer skin, artificial fibers extruded or extruded to form a sheath of different types of fibers, which are referred to as fibers in which the heterogeneous fibrous resin forms a core and a core (Jacaet). Composite fibers extruded in a by-side form are also used.

The "bonding fibers" or other adhesive fibers composed of such composite fibers should have a shallower melting point than the fibers which are bonded to form nonwoven fabrics. For example, "Perlon" is a nonwoven material. If used as a fiber, it is preferable to use "polyester" or "nylon 66" fibers as "adhesive fibers". And the "polyethylene terephthalic acid" based fibers are well adhered to the "copolyester" based fibers. However, the composite fibers of "nylon 6" and "nylon 66", each of which forms a core and an outer shell, are further bonded together for adhesion. However, when using composite fibers, the melting points of the resins of the fibers constituting the composite fibers must be different from each other, and the melting points of the fibers constituting the nonwoven fabric bonded to each other must be higher than the melting points of the two fibers constituting the composite fibers. Fibers of the "polyethylene terephthalic acid" type are most suitable and in some cases these fibers are used with "cellulose" or cotton or wool fibers.

As described above, the nonwoven fabric constituting each layer of the wick is preferably formed by randomly arranging the fibers constituting the wicks or by arranging them crosswise with each other. In some cases, the fibers are arranged in parallel with each other. In some cases, a combination of a random arrangement, a parallel arrangement, and the like are alternately used. The method of applying thermal adhesive to the surface to be bonded to the outer covering is to use a conventional method as described above. The arrangement of dots formed by the adhesive can be varied depending on the type of clothing to be used and the melting point used This 120 degreeC "terpolyamide" resin, or a conventional adhesive such as "copolyester" (copolyester) or other low-density "polyethylene" is used, the adhesive is always "adhesive" It should be applied to the side of the nonwoven fabric containing the least amount of fibers.

Other phenomena found through the present invention are that first, non-woven layers having less "adhesive fiber", including the surface on which the thermal adhesive is applied, are worn or washed during their heat resistance, i.e. wear or washing, especially "dry cleaning." It is said that the strength to withstand phenomena such as loss or chemical decomposition is relatively small. Once the wick is adhered to the outer covering, the entire composition including the outer covering, that is, the heat resistance of the garment increases.

The nonwoven layer comprising relatively few "adhesive fibers" among the nonwoven layers constituting the entire wick (i.e. the nonwoven layer occupying 40% or more and 80%) is relatively soft, and the soft nonwoven layer occupies this much ratio. It has also been found through the present invention to make the whole wick flexible.

A method of making a wick of clothing by joining multiple layers of nonwoven fabric is also disclosed in German Patent 2260677. In this patent, the nonwoven fabric of each layer is reinforced with a chemical adhesive and a dot adhesive is used. The "adhesive fiber" coverage of each layer is different from the "adhesive fiber" inclusion ratio of the present invention, and in other nonwoven wicks, the wicks that make up each layer are bonded to each other. Some parts of the same wick are more stiff with glue, while others are softer, so if you use this type of wick to create a clothing claw, there is a stiff part of the wick on the upper chest and a soft part on the bottom of the wick. It can be a part, but the wick of the present invention is soft throughout Geotyieoseo nonwoven interlining of the method will at all other with the core of the present invention is well suited especially haneundedo other words, in the core of the invention is joined to the thin and soft shell welfare and well-being denied junction.

Example 1

The nonwoven fabric is constructed using a generation of nonwoven fabric forming machines. The fibers in one machine consist of 45% weight "nylon 66" fibers (strength 3.3dtex) and 55% "nylon 6" and "nylon 66". "Composite fiber" (strength 3.3dtex) was used, and the weight ratio of "nylon 6" and "nylon 66" of "composite fiber" was 50% to 50%. Three nonwoven fabrics were obtained using "Nylon 66" and 10% of the "composite fibers" of the above, and the three nonwoven fabrics were staggered together, with the weight of each nonwoven fabric being equal and the total weight being 60 grams (60 g / 1 m ² ) per square meter.

The triple nonwoven fabric was bonded at 225 ° C through a splicer, or "calendar," which was engraved on one side of the calender, with a size of 0.5 mm x 0.8 mm x 0.65 mm. The point was divided into 2.1mm width and 1.6mm length, and the other syring was used. The nonwoven fabric containing a large amount of adhesive fibers is exposed to the point of the syrin, which is in contact with Laura, and the other side of the nonwoven fabric containing less "adhesive fibers" is called "terpolyamide", "nylon 66", "nylon 6" and A thermal adhesive consisting of "nylon 12" was embedded in the shape of several dots. The melting point of the thermal adhesive below was about 120 ° C. and 20 g of adhesive per square meter was poured using Sylinda without this point. And two Sylindas, Laura, went back and contacted the nonwovens at 10 meters per minute. The nonwoven wicks thus obtained were soft and pleasant to the touch, adhered well to the body, and had excellent heat resistance.

Comparison test

The machine of Example 1 was used to obtain three nonwoven fabrics of the same construction, 25% of the composite fiber of Example 1 and 75% of "Nylon 66" (strength 3.3 dtex). The total amount of fibers used is "nylon 66" or "adhesive fibers" as the amount of fibers in Example 1, respectively. The three nonwoven fabrics thus obtained were staggered and bonded in the same manner as in Example 1, and one surface of the nonwoven fabric was coated in the form of dots at a rate of 60 g / m ² .

The wick thus obtained was a wick that adhered to the body of the same soft touch as the wick obtained in Example 1, but the population was much lower, so it was weak to wear or wash (including "dry cleaning"), and washed five times with water and dry cleaning. As a result, the results of the two wicks were significantly different.
