Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to a raised fabric that has moisture permeability, waterproofness, and heat retention properties. (Prior art) In recent years, water from the outside has penetrated f-1', sweat from the human body has been rapidly absorbed into the outside, and furthermore, there has been little air flow.
．． (A moisture-permeable waterproof material has been developed that is comfortable to wear and has excellent heat retention, and is used for clothing such as sweatshirts and T-wear.)
・It is being done. The manufacturing method can be roughly divided into: (1) Porous film fabric method (=) I1 type Utsuno coating method (2) High-density woven fabric method. These have one opening hole that goes straight through the IJ suspension, and the size is 0. Water vapor (OL+04μ) passes through it, but water droplets do not pass through it, and as a result, it has the contradictory functions of moisture permeability and waterproofness. however,
This type has the disadvantage that if there is significant perspiration, sweat will form on the inner surface of the fabric because its moisture permeability is opaque.

【there was. On the other hand, Mino is a breathable and waterproof rain gear that has been used in Japan for a long time. Mino is a rain gear made from a laminate made of water-repellent straw and sedge.It is both a rain protector and breathable, so there is no binding even when sweating heavily, and it is extremely comfortable to wear. . However, it has the disadvantage that it absorbs water when worn for a long time, and the laminated wood made of straw and sedge has a rough and thin structure, so it does not have sufficient heat retention. Furthermore, it is known that the piles of flocked or pile Ih hanging are laid down in a certain direction and the surface is treated with water repellent treatment (
Utility Model No. 58-143824). However, this product did not have sufficient waterproofing effect and did not give satisfactory results (・Also, it was L-neutral in terms of heat retention that could be used even in extremely cold regions. (Objective of the Invention) The present invention is inspired by the structure of mino, and its purpose is to propose a raised tail that combines high moisture permeability, waterproofness, and heat retention. (Structure of the Invention) That is, the present invention A fabric having fibers, wherein the napped fibers are composed of napped-like napped T & fibers and fluffy napped fibers, and have water repellency, and the non-napped side of the napped fabric has a moisture-permeable and waterproof film layer. There is a raised fabric characterized in that it has the following features: further K, the moisture-permeable/waterproof film layer contains gold grain particles, or the non-raised side surface is the moisture-permeable/waterproof film layer; Further effects can be achieved by having a structure in which the raised fibers and the metal layer are logging.Synthetic fibers are preferably exemplified as the napped fibers used in the present invention, and the synthetic fibers include polyester fibers, polyamide fibers, etc. , poly7-crylonitrile fiber, etc. As the polyester used in the polyester fiber, polyesters having polyester terephthalate units as the main repeating unit are preferable, and among them, polyester terephthalate is particularly preferable. Alternatively, copolymerized polyethylene terephthalate, which is a copolymerization of inphthalic acid, 5-sulfate isophthalic acid, methoxypolyoxyer+lengelicol, etc., may be used.The degree of polymerization of the polyester depends on the type of polyester and the intended cross-section of the fiber. Depending on the shape etc.'1:
It should be selected appropriately, but in general, in the case of polyene terephthalate, one having an intrinsic viscosity [η] of 0.4 to 0.6 as measured in an O-chlorophenol solution at 35°C is suitable. . In addition, polyamides include nylon 6° and nylon 66.
, aromatic polyamide, etc. The cross section of the napped fibers used in the napped fabric of the present invention is basically a round cross section, but in order to further enhance the water repellent effect,
The ht+flat shape shown in Figure VC is best exemplified. FIG. 1 B) to B) are cross-sectional views showing examples of the transverse tljr plane of the napped fibers used in the present invention. Figure 1 f, I-
J is a plan view showing the shape of a hole in a die for obtaining a fiber having the cross-sectional shape of FIG. 1(C). The fineness of the napped fiber is 1~
60 de is used effectively, and in particular, 10 to 50 de is a preferable range from the viewpoint of imparting water repellent and waterproof functions. On the other hand, fluff-like napped fibers are preferably used, which are shorter in length than the napped-napped fibers, have finer single filament fineness, and are softer. The fineness of fluff-like napped fibers is 0.1 to 10 de.
j7 is preferred, and 0.1 de to 6 de is especially desirable. In general, when natural fur is analyzed, the napped fibers and fluffy napped fibers used in the present invention are thin, short, and dense fluff for the purpose of heat retention, and thick and long fluff to protect the fluff. Moreover, it consists of prickly hair with a tapered tip, and this similar structure can be used to create 6 pieces of raised hair using these synthetic fibers, such as knitted fabrics, #41 fabrics, non-woven fabrics A method of flocking the synthetic fiber to a fabric, a method of knitting it into a pile knitted fabric, and after knitting the pile knitted fabric,
A method of making a pile by shearing the tip of the pile, a method of knitting with a sliver knitting machine, a method of knitting with a sliver knitting machine, a method of knitting with a sliver knitting machine, a method of making a 2M thread on a double loom, and connecting two pieces of fabric with an E lowering between them. Conclusion (7
Examples include a method of obtaining pile fabrics by cutting the threads with a knife in piles that are piled up, and a raising method for woven and knitted fabrics. The thus obtained raised A6 woven fabric may be subjected to backing, brushing, polishing, etc. as required. Shearing processing, dyeing processing, etc. are performed. Among these, horitsuya processing is a process in which the tips of the napped fibers are stretched while being heated, and is effective for removing crimps from the raw cotton yarn, and a processing temperature of 150 to 250° C. is appropriate. There is no limit to the length K of the raised hair, but a length of 5 to 30 degrees is effective. In addition, the nap density of the nap fabric is 3,000 to 1
Suitable numbers are 5,000 per hole, and the nap length is 10 to 50 mm. As mentioned above, when making artificial fur similar to natural fur, it is preferable that the napped fibers be composed of thick, thick prickly hair component fibers and thin, fluffy fibers. The ratio of the length of the fluff component to the length of the prickly hair component is preferably 1/2 to 1/3. To make artificial fur, two different dissolution rates for nine solvents or two different hydrolysis rates for hydrolyzing agents are used.
The napped fibers are made of synthetic fibers with a higher than 100% strength, and are treated with a solvent or a hydrolyzing agent to dissolve or decompose more of the synthetic fibers that have a higher dissolution rate or hydrolysis rate, thereby creating shorter and shorter fibers. A method can be adopted in which a thin fluff component is used and a synthetic fiber with a low dissolution rate or hydrolysis rate is used as a thick and long prickly hair component. It can also be done by using the difference in shrinkage due to heat such as wet heat and dry heat. In addition, the Jlj rr used in the present invention is such that the napped fibers are placed against the base fabric, as shown in FIG. It is preferable that they are piled up at an angle of
FIG. Second
In the figure, 1 shows the prickly A14 napped fibers, 2 shows the fluffy napped fibers, 3 shows the base fabric, 4 shows the added coating, and 5 shows the metal layer winter. The napped fibers of the present invention need to be water repellent. Raised fJIt'14kK (!1 As a method of imparting water properties, a method of applying (hard water treatment?) to the raw yarn or raw cotton, a method of applying water repellent treatment to the raised fabric is used. Fluorocarbon water repellent such as fluoroalkyl acrylate and solifluid water repellent are used.The water repellent is applied to the surface of the fiber by applying the water repellent to the surface of the fiber. The tt+ method, the spray method, the corner ink method, the butt dry method, etc. are used.In order to strengthen the binding force of several groups of agents and 1. turbidity + tc
In order to improve this, it is also effective to use 4.18 agents such as Nikinito, Ehokino, and Enaleninoito in combination. In particular, in Book 91'', Meiji 9, pu in Figure 2 <The back side of the raised fabric, that is, the side opposite to the raised one, is coated with a waterproof/moisture-permeable film at the same time as before, or after a moisture-permeable film is applied, Furthermore, it is necessary to provide a metal 1- to facilitate heat retention.Methods include laminating a microporous film, or coating a microporous film on release paper by a wet or dry method. Transfer the film onto the A11 fabric using coach ink, or lift urethane resin, acrylic resin, ζ-related resin, vinyl chloride resin, 61:(fl vinyl resin, etc.) using an acupuncture method or dry method. Coach ink methods include floating knife coat, knife over roll coat,
Any method such as reverse roll coating or roll doctor coating may be used. Hooping after the water repellent treatment is advantageous in that the permeability of the film can be kept to an appropriate level. Moreover, aluminum is suitable for the metal part used in the metal 11iK. Aluminum may be applied by mixing it into the waterproof/moisture permeable film described in Part 1, but
It is better to apply this film alone by the ink method, the distillation method, the Fumi-Fut method, etc., as the effect will be greater. (Action of the invention) The napped fabric obtained in this way has a layered effect of water-repellent napped fibers that prevents 111 water from passing through from the outside. Even if rainwater passes through the napped fibers, the waterproof and breathable film provided on the back side of the fabric will completely prevent water from penetrating into the clothing. The juice follows the gaps between the waterproof/moisture-permeable film and the piloerection and is released to the outside, so there is no stuffy feeling, and even with intense interlocking striations, it feels good to the touch and is suitable for sports clothing, etc. In addition, there is a waterproof/moisture-permeable layer on the back of the raised 81 pigeon body and fabric, and a heat-retaining skin made of a metal layer like Al2)!
J! Houma larvae h' ist from Ic. Ordinary Lenoyer and Shishimata are also suitable. . Adding a gold maple layer (to improve quality) is an application of Qi Fahin's heat retention principle to clothing, and the innermost layer absorbs radiant heat radiated from the human body. +1: The non-piloerection area reflects the hot air and reduces the amount of conductive heat. Wearing warm clothing depends on whether you can absorb as much static air as possible from the chemical MMK of the fibers, and absorb a lot of the pressure inside your clothes. Heat retention refers to the difficulty in transmitting heat, so if we express it in the form of heat resistance, just like air resistance, it will be proportional to the thickness of the cloth.
- If a metal film is provided on the nape cloth (A), which has the effect of reflecting the radiant heat that the Flumi membrane has, a nape cloth C with extremely high heat retention properties will be obtained.

This sliver was knitted using Slyha 12 Sauteink 41K manufactured by Wildman, USA. In this case, 100% polyester 14/- spun yarn was used as the subsystem. Composition Nayu 7 was split into wheat, hackcoach inked with acrylic resin, heated at 120°C,
Fixed the hair. Next, the pile was cut into lengths of about 2 mm by shuffling and subjected to polytunya treatment three times at 200 DEG C., 160 DEG C., and 120 tLO% to remove the standing fibers. After that, I performed further shuffling and straightened the hair with a trowel with 2 cm of VC. The nap density of the obtained nap fabric was 9. L10
It was 0 pieces/side. Next, an aqueous treatment agent (viscosity: 6,0007 nm) containing 20% of caustic sorter and 2.5 parts of Fulgin's soda was coated on the raised fluff surface by a screen method to give an adhesion of 1.2&/a+l. After that, without drying, it was heated to 100℃ in a steam heat treatment equipment.
Steeming treatment was performed for 20 minutes ju1, followed by washing with water and drying. The raised part of the raised cloth thus treated consisted of long, thick thorns and thin to fluffy fluff, and the φ11 hair had no crimps and was well elongated. Next, staining was carried out under these conditions using a high-pressure staining image.
