Description

Multi-function skin-core fiber cool feeling tannin cloth manufacturing method

The object of the present invention is to provide a method for manufacturing a cool tannin fabric which has both a sweat-absorbent, a heat-resisting, a cool-sensing, a quick-drying, a gloss, and an ultraviolet-resistant fiber. The structure of the fabric is made up of three different fiber yarns into a single composite yarn, which is used as a weft thread, and then weaved by a specific yarn weave or a unique warp and weft to achieve a breathable effect.

The characteristics of the island-type climate: hot and humid summer, it will make people feel very uncomfortable. In order to improve the way, the material of the outdoor clothing must take into account the heat resistance, luster and anti-UV function. In the indoor, especially in the air-conditioned room, the material must absorb sweat, coolness and quick-drying. The technical field of the present invention solves this problem.

There are two types of traditional summer heat-resistant fabric materials, one of which is natural hemp, which has the characteristics of stiffness, breathability and strong water absorption for summer heat resistance. However, the disadvantage is that the material is stiff and the skin feels slightly rough, which is less suitable for close-fitting clothing.

Traditional summer heat-resistant fabric materials are natural silk, and the skin feels cool and shiny, so it is suitable for summer heat resistance. However, the disadvantage is that the material is quite soft and slippery, it is too drooping to wear, and it is easier to stick to the body after sweating, resulting in inconvenience.

Since the earliest synthetic fiber in 1931, polyamide fiber, after the market of nylon (Nylon), various synthetic fibers such as Polyester, especially polyethylene terephthalate (PET). These two synthetic fibers each have their own characteristics, such as nylon The advantages are toughness, wear resistance, smoothness, light weight, insect resistance, mildew resistance, good heat dissipation, quick drying and cool feeling, and the material is not easy to generate static electricity, deformation, fluffing ball and old damage. Polyethylene terephthalate (PET) fiber is often combined with other natural fibers to show the characteristics of both. Cotton-polyester clothing has toughness, wrinkle and tear resistance, and is not easy to shrink. The advantages of quality clothing. Polyester fiber has poor gas permeability, making moisture difficult to disperse. How to make synthetic fiber, has the advantage of coolness, but can combine the advantages of various fiber elements, complement its shortcomings, and become the purpose of creation or invention of many fabrics.

The main principles of the commercially available cool sensation are three types. First, the synthetic fiber is blended with ore material, and the synthetic fiber is mixed with a material having cooling characteristics. This cool sensation is more common in the market. In the spinning process of synthetic fibers (such as polyester fiber polyethylene terephthalate, nylon Nylon), materials such as ore powder, jade powder, or special coolant are applied to the surface of the yarn.

Compared with the textile material, the ore has a small specific heat and a fast heat balance. When the clothes with added ore powder are put into the air-conditioned room, it can quickly balance with the ambient temperature to achieve a rapid cooling effect.

Disadvantages: Because of the textile material, the ore has a small specific heat and a fast heat balance. In a hot environment, the temperature is relatively hot. In a high temperature environment, wearing this cool sensation will feel hotter than the general textile clothing.

The principle of the cool sensation, the second, through the weaving of the yarn or the warp and weft interlacing to achieve the breathable effect. This kind of synthetic fiber is made into a cool sensation coat, which is usually drawn into a cross-shaped or Y-shaped shaped cross-section yarn, which is woven into a loose and breathable knitted fabric to enhance the effect of ventilation and perspiration.

Disadvantages: However, because the cross-shaped or Y-shaped cross-section yarn method is adopted, although the temperature is raised fast, it is more comfortable than the general clothes in the comfort of skin contact. However, because of the high temperature in summer, the human skin is quickly wicked. When wearing this cool sensation, it will be because Covering the clothes, so that hot sweat can not be quickly discharged, feeling more stuffy. At the same time, if the cool sensation is less than the humidity of the sweat, the synthetic fiber is easy to rub against the skin to generate static electricity, and often has a itchiness when worn.

The principle of cool sensation, the third is to mix hydrophilic materials, and mix a large amount of textile materials with good water absorption such as cotton, mucus 缧萦, copper ammonium 嫘萦, etc., or hydrophilize on synthetic fibers or fiber surface. deal with. This type of cool sensation does not give people a feeling of coolness in the moment, but it does not cause heating in a hot environment, and the good sweat absorption function brings moderate resurgence, comfort, and non-stickiness, so that the body produces a wet Cool feeling, it is really suitable for summer.

The disadvantage is that it is not easy to dry after a lot of water absorption. Therefore, after the exercise or the sun, when sweating, if you immediately enter the air-conditioned room, the wet clothes will instantly become cold, and it is easy to let the body catch cold. In addition, after absorbing sweat, it is prone to sweat odor and sultry sensation.

In the pre-existing case of the Republic of China patent, there are also many creations and inventions of cool-sensing fabrics, such as application number 103208216 bulletin number/certificate number M485623 ice-cold towel, application number 102216817 bulletin number/certificate number M476787 cooling fabric COOLING FABRIC, application number 101222816 announcement No. / certificate No. M456187 cooling and heat-wearing clothing and accessories, application number 100219409 bulletin number / certificate number M433107 seamless molding bra cup structure with cool cooling function, application number 101200727 bulletin number / certificate number M431579 bra pad with cool cooling function Sheet structure, application number 101201398 bulletin number / certificate number M430383 fabric structure of cooling garment, application number 101200203 bulletin number / certificate number M429585 fabric with cooling effect, application number 101211742 bulletin number / certificate number M445931 with nano anion oxygen cold , Application No. 100111465 Announcement No./Certificate No. I475137 Multilayer Structure Braided Fabric and Fiber Product Containing Same, Application No. 101130584 Publication No. 201346084 A Cooling and Cooling Fiber, Preparation Method and Textile, Application No. 087117197 Announcement No. / Certificate No. 448254 UV resistant polyester composition and the fibers and cloths made therefrom.

These patents do not have the above three cool sensation principles, and all have their advantages and disadvantages. Therefore, it is necessary to develop a cool denim fabric that can have the advantages of a cool coat in the summer, to solve the six kinds of needs of sweat absorption, heat resistance, coolness, quick-drying, gloss, and anti-UV. A method for producing fibers and composite yarns thereof.

The denim fabric of the general jeans mainly uses natural cotton or jingle raw materials, in addition to good touch and softness, coupled with good water absorption and not sultry to wear, it is widely accepted by the public. However, under the influence of the greenhouse effect and the weather is getting hotter, the shortcomings of the general jeans include: the heavy, the wet stickyness of the skin, the slow drying, and the poor heat resistance due to low heat dissipation, which has become an urgent problem to be improved.

In view of the above, the present invention has been developed to solve the object of the present invention, that is, to improve and solve the problem of uncomfortableness of the conventional jeans through the invention of the composite long fiber, and the composite fiber used has both sweat absorption and heat resistance. Cooling, quick-drying, gloss, anti-ultraviolet and other multi-function cool feeling tannin fabric manufacturing methods.

To achieve the above object, the present invention adopts the following technical solutions:

In view of the high moisture content (8%) of natural cotton, the disadvantage is that there are many hairiness and hinder the heat transfer rate.

Rayon has a cooler moisture content (12%) and is cooler to wear. However, if the staple fiber type is used, it still has a lot of hairiness, and after sweat absorption, it is not easy to dry, and it is easy to produce odor and wet viscosity.

The invention is used as a composite yarn of jeans, wherein the weft is a three-layer yarn The line structure is as follows:

The outer layer is made of rayon fiber (Rayon) long fiber material made of wood pulp, which is designed to maintain high moisture content, wear cold characteristics, avoid short hairiness, improve heat diffusion rate, and quickly absorb water and reduce skin surface moisture. Sticky and hot.

The middle layer uses a composite sheath core structure, and the core layer is made of polyethylene terephthalate fiber (PET) made of polyester fiber material, and a high content of anti-ultraviolet material is added, and the skin layer is made of high water content nylon material to improve the chill feeling of the yarn. .

As a preferred embodiment, the polyester fiber is used for the core layer, mainly because the polyester fiber has dimensional stability and high dye stability, and the fabric quality can be stabilized.

As a preferred embodiment, the core layer uses a profiled section of polyester fiber to increase the moisture diffusion rate of the fabric and reduce the drying time of the fabric.

As a preferred solution, the core layer uses a high level of UV-resistant material (such as titanium dioxide), which can prevent ultraviolet rays and infrared rays from invading the skin, reduce the damage of the sun to the skin, and increase the temperature of the body surface due to sunlight.

As a preferred solution, the core layer is made of a high-content ultraviolet-resistant material, which prevents the anti-ultraviolet material from rubbing against the woven fabric needle during weaving, resulting in unstable fabric quality.

As a preferred solution, the use of the inner layer of the sheath-core structure can reduce the moisture content of the overall yarn and increase the sweat diffusion area and increase the yarn drying speed.

As a preferred solution, the use of a layer of a core-sheathed yarn can improve the low tensile strength of the Rayon filament and increase the durability of the fabric.

As a preferred solution, the middle layer of the yarn core structure can be used to slightly increase the hardness of the fabric, and the low-weight tissue design can improve the overall texture of the fabric and avoid Soft touch.

The inner layer is made of an elastic material such as a spundex high-elastic PU material or a polytrimethylene terephthalate (PTT)/polyethylene terephthalate fiber (PET). Ester fiber elastic material to improve the wearing comfort.

The combination of yarns can be double-packed, squirted, combined or otherwise.

There are also specific definitions of the constituent fiber components of the three yarns. One of them provides a synthetic fiber which has both heat resistance, ultraviolet resistance, fast heat dissipation and sweat absorption, and is compounded into a composite yarn by these three kinds of yarns.

The invention belongs to the innovative structure of synthetic fiber. Although the titanium dioxide (TiO2) of the ore powder is infiltrated, the ore powder is added to the polyethylene terephthalate (PET) of the core layer due to the core-fiber composite mode. There is no disadvantage of adding the above ore powder.

The present invention encompasses such a class, but there is a completely new approach to synthetic fibers that overcomes the shortcomings of the prior art described above: it does not dry easily after a large amount of water absorption. Therefore, after the exercise or the sun, when sweating, if you immediately enter the air-conditioned room, the wet clothes will instantly become cold, and it is easy to let the body catch cold. It is best to change clothes to avoid a cold. In addition, after absorbing sweat, it is prone to sweat odor and sultry sensation.

The invention adopts nylon material to conform to the natural silk touch and cool feeling, but avoids the problem that the nylon material is too soft. Therefore, the polyester fiber material is added to give it a natural hemp stiffness. It has the dual advantages of polyester material and nylon material, but the chemical fiber wears a sweltering disadvantage because the chemical fiber surface has no hydrophilic base and cannot absorb sweat actively.

In order to make the chemical fiber yarn absorb sweat quickly, instead of just feeling the coldness of the moment, it is impossible to maintain long-term coldness, so it is necessary to add a strong water-absorbing natural material. Wood pulp rayon (Rayon), It is a natural material, its moisture wicking ability is 150% of natural cotton and because of the touch, cold as natural hemp, so it is more suitable for spring and summer use.

According to the cooling test report of Taiwan Textile Research Institute (TTRI), it is confirmed that after simulating human body sweat, the composite yarn fabric can be reduced by 5 degrees after absorbing the water equivalent to the human body temperature, and the natural cotton fabric can only be reduced by 3 degrees, so It is certain that the composite yarn woven into the denim fabric is comfortable to wear in the summer, far more than natural cotton.

In short, the composite yarn can replace the new generation of natural hemp, natural cotton and natural silk. It combines natural materials and functional chemical fiber materials. The overall physical properties not only exceed natural materials, but also like technical linen, and can be applied to various fabric fields. Century-class goods. Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it is known from the above technology that it has the following absolute advantages:

Natural synthetic fibers and permanent functions are not affected by time and detract from their benefits.

It has the effects of indoor cold, outdoor sun protection, lustrous texture, sweat absorption and quick drying, and sweat absorption and cooling.

The fiber from the source of xylitol raw material is used to absorb sweat and cool down.

In order to more clearly illustrate the principles of the present invention, and the actual aspects of the method of making the denim fabric, to demonstrate the efficacy of the method of manufacture, the following description of the invention will be described in conjunction with the accompanying drawings.

Please refer to the first figure to illustrate the principle of the cool sensation clothing 1. There are three types. The first type is made of a material with cooling characteristics. The cooling characteristic material is smaller than the heat of the clothing material and has a fast heat balance. For example, ore powder, jade powder or other cooling substances 2; the second type is the weaving effect of weft and warp weave, such as cross-shaped, Y-shaped weave 3; the third type is mixed with hydrophilic material or surface hydrophilic processing, such as having sweat absorption The role of cotton, mucus 缧萦, copper ammonium bismuth, etc. 4

Please refer to the second figure to explain how the new generation of synthetic fibers replace natural hemp 6, natural cotton 7 and natural silk 5. Natural silk 5 has the advantages of cold touch and good luster, but it also has the disadvantages of soft, coveted and sticking to the body. It can be replaced by nylon (Nylon) 8, but because it is too soft, it is necessary to use polyethylene terephthalate. Ester fiber (PET) 9 reinforced; natural hemp 6 has the advantages of breathable, absorbent, cool, but also has the disadvantage of stiff and rough touch, can be replaced by polyethylene terephthalate fiber (PET) 9, but still The disadvantages of sultry and non-absorbent sweating are necessary to reinforce with Rayon 10; natural cotton 7 has the advantages of water absorption and perspiration, and also has the disadvantage of a large amount of water absorption and drying, and can be replaced by wood pulp fiber (Rayon) 10. Because it has the characteristics of water absorption and water release 150% natural cotton.

The composite yarn structure is, in a nutshell, a layered composite of various fibers. Each fiber has different components and different characteristics, so that each layer exerts different effects, thereby simulating natural cotton 7, natural hemp 6 And the characteristics of natural silk 5, while having the superiority of synthetic fiber Point, mutually complementary natural cotton 7, natural hemp 6 and natural silk 5 and polyethylene terephthalate fiber (PET) 9, nylon fiber shortcomings, to achieve the best results.

Referring to the third figure, the present invention utilizes three different yarns and combines them into a single composite yarn by coating. The composite method is a sheath-core fiber in synthetic fibers.

The sheath-core composite fiber is composed of a polymer of different properties or structure surrounded by one component or coated with each other and composited along the axial direction of the fiber.
