Description

[Detailed description of the invention]

(Technical field) The present invention is an IC with a luxurious feel and fur-like texture that has an excellent feel and appearance, and the other side has a silver-like leather-like texture, making it flexible! r! This relates to a reversible type special sea 1~-shaped item with the 1st cup turned to the right. <Prior Art> In the past, efforts have been made to make the materials as close as possible to natural fur and natural leather, and research and development have been carried out on artificial fur and silver-finished artificial leather 11 of considerable quality. First of all, research on artificial fur is being carried out by closely examining natural fur and knowing that it is made up of prickly hair and fluff. Focusing on the thin and pointed tip of the chunin's hair, efforts are being made to create this artificially.Furthermore, history has shown that these prickly hairs become slightly thinner at the base. However, it is very difficult to make such a woven Iff (although it is very difficult, but it has been tried by many methods, and recently a fairly similar one is being provided. Artificial leather 71'L has been researched for even longer than artificial fur, and although it is not perfect, it has an appearance that is quite close to natural products.However, until now, one side has a fur-like appearance, or It was made of fur-like material with a silver surface, and the other side was of poor quality and roughness, and at first glance it was obvious that it was the reverse side.In other words, the pace fabric was either intact or had been processed. However, it is just a rough and rough finish for the w side.The fact that one side has a fur-like finish and the second side has a leather-like finish with a silver side indicates the characteristics of each side. It is said that it is difficult to process it while it is still alive.The features such as the sword straw, fur-like appearance, touch, and air marks are preserved.
When silver (=J) processing is applied to the back side, the fur-like features are often lost, and the texture and touch of the raised side may be particularly poor. (Objective of the present invention) The present invention The object of the present invention is to provide a novel reversible type sheet-like material having novel characteristics not seen before, and having both a fur-like raised surface and a leather-like silver surface. Another purpose is the structure J3 that is not found in natural leather.
It has a good appearance and characteristics, and one side has a luxurious appearance,
It has the characteristics of natural fur that has never been possible with other materials, such as soft touch, fluffy feel, warmth, air mark, and air vibration properties, and the other side is natural. It is composed of a grain type that is completely different from the 4111 composition of °1, and has the previously unimaginable characteristic of natural leather, in that both sides can be used freely depending on the purpose of use. Moreover, it is an object of the present invention to provide a completely novel special sheet-like material having fur-like and leather-like characteristics in the same manner (1,1). After repeated inspections, we arrived at the present invention. (1) One side has ultra-fine man-made fiber naps with a fineness of 0.5 denier or less, and the fiber length of the nap part is 5 to 5 minutes from the base material. 3
A reversible type special sheet-like material having a uniform raised part with a raised length of 0+nm, and the other side being a silver surface composed of a film made of an elastic polymer. (2) 4ii Slender I! i. A reversible type special sheet 1-like article according to claim (1), characterized in that the filament hairs are crimped. (3) The special reversible type reversible type recited in claim (1) characterized in that the membrane made of an elastic polymer has many micropores of 50 microns or less to improve air permeability and moisture permeability. Sea 1-like thing. (4) A reversible type special sheet material according to claim (1), characterized in that the film made of an elastic polymer material has a drawing pattern.

(8) Claim No. 1, characterized in that the membrane made of an elastic polymer is a microporous membrane and has moisture permeability.
) Reversible type special sheet-like material described in item 2. (7) ■Extra fAll fiber with fineness of 0.5 denier or less 1
[First step of creating a napped product with a napped length of 5 to 30 mm from the base fabric using the generated fiber for the napped part, then 1
The second step is two-stage dry heat treatment at 30-140°C and 170-180°C. ■Pile standing? A third step of ultra-fine treatment of the Goku@I fiber fibers 1 used for 1ilf; ■ A fourth step of forming a film of 11 21-molecule bullets on the other side opposite to the raised part; ■Hot water treatment a>J: A fifth step in which rolling and rolling are performed simultaneously; This invention relates to a method for manufacturing a reversible type special sheet 1 sheet-like product. By forming JJ, a special sheet-like product JJ (7° configuration can be obtained). will be described in more detail.As the fiber constituting the fur-like nap of the present invention, ultra-fine navy blue with a thickness of 0.5 denier or less is used.If it is thicker than 0.5 denier, the touch will be rough, so it is not preferable. Many of the effects of the present invention, which will be described later, cannot be achieved.In particular, the denier is preferably 0.06 to 0.3 denier.0.06 denier J: If it is too thin, it will be difficult to apply color, or even if the appearance L° The fastness often deteriorates.This tendency is particularly strong when using polyester fibers, which can be said to be preferable for the present invention.If the fiber is thinner than 0.3 denier, it is flexible and J
: A much softer one-touch product can be obtained. The material for forming the raised lf4 may be any man-made fiber that can be extremely deep blue, including polyethylene terephthalate-1-1 or a copolymer thereof (for example, a copolymer component such as 5-sodium musulvoisophthalate). Such)
, polybutylene terephthalate-1 or copolymers thereof, nylon 66, nylon 6, polyacrylonitrile polymers, regenerated lerulose, and the like. As for the manufacturing method of the ultrafine fibers that constitute these naps, for example, it is preferable to generate ultrafine fibers from ultrafine fiber Il1 generation type fibers, and specifically, from sea-island composite fibers or mixed spun fibers. Known methods can be used without any particular limitation, such as removing the sea component from the peelable composite 11i and making it extremely fine by peeling from the peelable composite 11i navy blue. The fur-like sheaths 1 to 1 of the present invention may have any structure as long as the flocking method using electrostatic flocking is taken into consideration, and films and plastic sheets are also possible, and of course, any structure such as woven fabrics, knitted fabrics, and non-woven fabrics may be used, and fabrics are also preferred. More specific examples include double velvet, single pile double velvet, double pile double velvet, double sided velvet, chinchilla weave, fabrics using chenille yarn, plush. Human, wireless velvet, velvet weave for imitation fur, 1~ricott napped knitted fabrics, other vertical knitted wool products,
An example is a nonwoven fabric made by needle-punching a nonwoven fabric using a needle bump needle with a large barb to increase the amount of hooking on the barbs, and bundling and raising the nonwoven fabric. The hair length needs to be 5 to 30 strokes. If the 5th lock J: is too short, the effects of the present invention, such as the air mark and air vibration brake 31, will be diminished, which is not good. 6-15 mm ifi Itl is also preferred. Particularly preferred is around 1101n. If the length is longer than 30 mm, the product will be too heavy and the nap will easily get tangled, making it difficult to weave, knit, or form into a sheet. Next, this raised sheet material was heated to 130~1=10'C and 1
In two stages at 70 to 180℃ (-J and dry heat outside 11!1
It is necessary to use a straw heat set. This is because the nap length is as long as 5 to 30 mm, so one-stage heat treatment at high temperature causes uneven shrinkage in the length direction of the nap, which is undesirable. By first performing dry heat shrinkage in the range of 130 to 140°C and then dry heat shrinking at a high temperature of 170 to 180°C, a raised product of a constant length with a stable shrinkage rate can be obtained. . After carrying out the two-stage dry heat treatment (heat treatment), it is necessary to subject the green fibers of the ultrafine fibers used in the napped portion to ultrafine treatment. When the fM 111 fiber-generated fiber is a sea-island composite fiber or a mixed spun fiber, it is washed and covered with a solvent that elutes the sea component. In addition, in the case of a releasable composite fiber set, it is possible to add an auxiliary agent that separates or loosens the components, or to create multicomponent fibers with different shrinkage rates.
Other physical methods are also used to make the material thinner. Furthermore, at least part of these erected piloeres forms bundle-shaped middle-eastern erected piloeres consisting of one fiber, and the middle group of the erected piloes is reduced in number, and the tips of the erected piloes are tapered to form large clusters that look like scales. Moreover, it is preferable that the crimps be accompanied by crimps on the ultra-slim person 3: mussels and navy blue. Through the above 4.74 formation, the fur-like raised surface becomes a sheet-like material with high-quality raised fur for the first time.
It is extremely smooth, has a warm touch, has a luxurious appearance, is reversible in the way the hair falls, and has a unique appearance with a scale effect, glossy effect, three-dimensional effect, joke mark, and air mark. It can be used as a jLK-grade hair-like hair surface that has an air vibration effect. In the present invention, it is important to carry out the following step, that is, to form a leather-like silver surface on the back surface of the napped sheet material. This structure is completely different from the structure of natural fur, and is unexpected if the intention was to make it similar to natural fur. Applying this silver surface finish to the back surface was first made possible in the 414-year-old autumn fabric of the napping sheet of the present invention mentioned above. Using navy blue, further 2
After drying and heat treatment, no matter how the raised hairs fall during processing, the object of the present invention can be achieved by simultaneously performing hot water treatment or rolling processing that is carried out after grain processing. It can be anything like 1 h, especially sea 1 ~. Next, we will explain about the other side, which is silvery and non-piled.J-
Ru. First, 11) Molecular elastic bodies consisting of 414 leather-like silver surfaces include polyurethane, di-lyl-butadiene rubber, polyvinyl chloride, polyvinyl chloride, polyamide, etc., and polyurethane is preferable for Qh. The polyurethane preferably used in the present invention is a polymer obtained by reacting a polymeric diol with a diisocyanate and a chain extender. , polyether glycol, polyester glycol, polyether ester glycol, etc., having a molecular weight of 500 or more, preferably 1000 to 5000. Typical examples thereof include polyethylene A oxide glycol, polypropylene oxide glycol, and polycaprolamine glycol. , polyethylene adipate, polybutylene adipate, bolite 1-
Ramethylene adipate-1 may be used singly or as a mixture. Organic diisocyanate 1 is diphenylmethane.
Examples include 4,4'-diisocyanate, 1 to lye diisocyanate, hexamethylene diisocyanate to 1, isoborone diisocyanate to 1, and mixtures thereof. Chain extenders are compounds with two functional groups that react with the upper diisocyanate, and glycol chain extenders include ethylene glycol, propylene glycol, and butylene. These include glycol, diethylene glycol, and tri-nitylene glycol. Examples of the diamine chain extender include 4,4'-diaminodiphenylmethane, 1-lylenediamine, 4,4'-diaminodicyclohexylmethane, and mixtures thereof. The present invention uses the above-mentioned 13-molecule elastomer to process a leather-like silver surface. By applying it to the other side of the substrate opposite to the napped side and forming a microporous membrane through wet coagulation, fine solids were added to 11 181 molecular bullets and the solids were eluted after solidification. Add a foaming agent and foam after solidifying! Methods for forming fine pores, dry coagulation, heat curing, graining, surface finishing, etc. There is a method of applying a polymer elastomer composition on top of the elastomer composition, bonding it to the substrate while it is still sticky in a semi-dry state, curing it with heat, and peeling off the release paper. In the present invention, the latter method is preferably used. The film thickness of the polymer elastic body can be adjusted as appropriate depending on the purpose of the sheet-like product. In the present invention, it is preferably 100 microns or less, particularly 50 to 30 microns. A film thickness of microns is preferable. If the film thickness is 100 microns or more, the polymeric elastic material will have a strong rubbery feel, be hard, and have a poor texture, and the rough texture of the raised surface will not be utilized. A film thickness of 50 to 30 microns is preferable in order to obtain a sheet-like product with a soft texture and excellent appearance quality with appropriate wrinkles. The structure of the present invention exhibits its effects through the step of performing hot water treatment and rolling at the same time. Next, this step will be explained. A detailed explanation of performing hot water treatment-3 and rolling at the same time. Rudo refers to introducing the special sheet-like material obtained by the present invention into a hot water bath and rolling it in hot water.Hot water temperature polishing is preferably in the range of 80 to 140°C. , especially preferably 110 to 130°C.The rolling process can produce sheet-like objects.

[It is preferable to rub it randomly. To explain more specifically, the Sea Mill-like material of the present invention is endlessly placed in a liquid flow pressure processing machine, hot water is circulated,
The sheet-like object is moved by the power of the hot water, and during that time a special nozzle is used to squeeze the sheet (~-like object),
~-like items! This is done by rubbing and kneading. In response to this action, the lithium-like materials are randomly kneaded in a hot water solution. If the temperature of the hot water is below 80°C, the artificial fibers used for the napping will not separate sufficiently, resulting in a poor rolling effect. Also 1
At temperatures above 40 degrees Celsius, the man-made fibers deteriorate and the nape become sloppy and tangled, which is undesirable. Needless to say, the preferred method is to dissolve the dye that will stick to the artificial fibers in hot water and perform the dyeing process at a rate of 1 yen. At this time, it is also preferably used in the present invention to dye the raised hair in a color different from that of the polymer elastic film. Rub processing in hot water 11! There is no particular limitation between i, but 4
A time period of 0 to 90 minutes is preferably used. Only by performing this hot water treatment and rolling process can the object of the present invention be achieved. When one component is removed using a solvent in ultra-fine processing, a drawing process is performed using a mangle, but this process may cause the naps to fall in one direction, or the nape surface may be held down or pressed during grain processing. Therefore, this kneading process is necessary to loosen the raised hair that has fallen in one direction or randomly during these steps, and to make the raised hair stand up fluffy even if it is slightly aligned in one direction. Furthermore, this rolling process is preferably carried out in water, and moreover, hot water is particularly preferable in terms of dispersion of the raised fluff and linearity. Next, this special sheet material is subjected to finishing treatments such as application of a finishing agent, finish setting, and brushing, which are carried out on ordinary fabrics. As finishing agents, all those commonly used as textile finishing oils, such as smoothing agents, softeners, antistatic agents, and water retention agents, are preferably used. After applying the finishing agent, the finishing cera 1 is dried and then brushed. The configuration of the present invention is shown in the drawings and will be further explained in detail in R1. FIG. 1 shows a model cross section of the product of the present invention. Figure 2 shows a cross-section of natural fur as a model. In the figure, A is a napped layer made of ultra-fine artificial fibers, B is a base material, C is a non-napped silvery film layer made of an elastic polymer, and D
indicates fluff, E indicates prickly hair, ]: indicates grain layer, and G indicates IIi fiber layer. As is clear from a comparison between the product of the present invention in Figure 1 and the natural fur in Figure 2, there has never been an artificial product C (IIS construction). Therefore, a product with the structure of the present invention had not been made, and there was no need for a double-sided product.It goes without saying that it is compared with natural fur, but the raised part of natural fur is fluffy. However, one of the features of the present invention is that it has a structure with long fluff.Furthermore, in natural hair, there is a silvery layer (i.e., 1) at the root of the erect hair. There are similar layers. In comparison, the product of the present invention has a membrane structure made of polymeric elastic material on the side opposite to the napped side, and has a special surface that corresponds to the natural grain layer, which is completely unthinkable from natural fur. By adopting this structure, the object of the present invention was achieved. (Effects of the present invention) The effects of the present invention are enumerated as follows. (1) The raised surface has an extremely smooth touch. (2) One side has a fur-like surface and the other side has a leather-like silver surface.
It is a reversible type. 3) The raised surface is suede-like, and has a warm feel with a fluffy, fluffy fur-like feel. (4) Both sides have a DJ appearance with high quality features. (5) Since it is made of man-made fibers and has a fur-like appearance, it does not have unpleasant odors or be eaten by insects and can be easily washed. (6) The piloerection can fall in either direction, which is possi-reverse. (7) Has an air mark effect. An air mark is when air is blown from a pointed mouth and an Ll or C1~ shaped object is moved relatively.
It means that there are traces of the air being blown. Of course, it will disappear if you rub it with your hand. (8) Eliminate the air pipe recon effect. Air vibration is a phenomenon in which when you pout and blow air toward the hair, the piloerection spreads in all directions, and at that time the piloerection sways as if it is vibrating. <g) The other side is silver (= J type, with a good skin-like appearance and wrinkles. (10) Create a unique luster on each side. Especially the raised side by hand. The gloss differs between the pressed part and the unpressed part, which is one of the features of the present invention.The special sheet-like material obtained by the present invention may be used for clothing such as two-one hair blazers, Upholstery shoes 1
It can also be used for furniture, such as on the surface of wood. It is also preferably used for industrial material applications, such as heat insulation materials and wiping materials. Next, Examples will be described, but they are intended to explain the present invention more clearly, and the present invention is not limited or restricted thereby. Example 1 Polyethylene terephthalate 1 was applied to the warp and weft of the base material.
A 50 denier, 24 filament false twisted yarn is used as the pile yarn, and the island component of the sea-island type composite fiber is polyethylene terephthalate, the sea component is polystyrene, and the island component ratio is 8.

1-do weave (pile fabric with 10 pile threads) The weave density at this time was 94 pile threads (warp threads)/111,
Base warp threads 94/in, base weft threads 120/11). This pile fabric was dried in a pin tenter by 1 positive rotation heat set 1-1 at 130°C, and then 2 positive rotation heat set 1-1 at 180°C.
~ was done. In this two-stage set 1-j; repiling length is 1
It shrunk by 8% and became 8.2 parts per meter. This pile fabric was washed five times with trichlorethylene to dissolve and remove the borisdylene used as the sea component, and the pile yarn was subjected to ultra-fine treatment. After the polar 111+1 treatment, the pile surface had raised piles falling in one direction. 10% polycaprolactone polyurethane
Apply the solution to a release paper with a Kerno-like diaphragm using a knife coater so that the dry coating becomes 7 microns, and heat at 120°C.
The solvent was completely dried. A 25% solution of an adhesive paint consisting of polycaprolactone-based polyurethane and a crosslinking agent was applied onto the rough surface using a knife coater.
After removing part of the solvent, it was fixed on the back side of the pile fabric while it was still sticky, and aged at room temperature of 40° C. for 21 hours. After that, the release paper was peeled off, and the grain layer with a kerf-like drawing was made into a sheet-like material.At this time, the raised pile on the pile surface was flattened in one direction. This sheet-like material is put into a dyeing machine in an endless manner, and an aqueous solution of disperse dye is added thereto, gradually heated, and rolled at the same time as dyeing J3 and heat treatment of the sheet-like material. I did it. At this time, the product was rubbed in hot water at 120°C for 60 minutes. The rolled product was slowly dried in a dryer at 80°C, and then dried at 100°C.
Finishing work was carried out. The sheet-like material taken out from the dyeing machine had its raised side facing in one direction, making it hard to believe that it was a raised product, but as it slowly dried, it became soft and fluffy, making it look like fur. became. Thereafter, the raised surface was brushed three times in forward and reverse directions using a brush roll to finish the product. This item is a fur-like napped product with one side covered with ultra-fine napped hair, and on the other hand, it is a leather-like non-napped product with a 1-F style tie and is reversible. 1
It was something like ~. This Sea 1 hemlock is used without lining.
When I sewed it to -1-, it was a high-quality coat that could be used on both the front and back sides, and was warm and soft to the touch on the raised side.
