Description

 Multi-functional sheath core fiber and manufacturing method thereof  

The invention provides a method for manufacturing a multi-functional sheath-core fiber and a composite yarn thereof which have the functions of sweat absorption, heat resistance, coolness, quick-drying, gloss and ultraviolet resistance.

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 materials, one of which is natural hemp, which is characterized by stiffness, breathability and strong water absorption, which are suitable 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.

The traditional summer heat-resistant material is a kind of natural silk. The skin contact feels cool and lustrous, 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 kinds of synthetic fibers have their own characteristics. For example, nylon (Nylon) has the advantages of 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, Hairball 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 many creations or inventions.

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. Add ore powder, jade powder, etc. to the spinning process of synthetic fibers (such as polyester PET, nylon Nylon), or apply special coolant 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 covered by the outer garment, so that the hot sweat can not be quickly discharged, and it feels 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 it is often itch 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, rayon (Rayon), copper ammonium ruthenium, etc., or on synthetic fibers or fiber surfaces. Hydrophilic processing. 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 that have a sense of coolness, such as application number 101223430 bulletin number/certificate number M456187 cool-sensitivity cooling yarn and fiber products made therefrom, application number 100111465 bulletin number/certificate number I475137 multi-layer structure woven fabric and fiber product containing the same, application number 096138872 bulletin number/certificate number I350872 long-acting cool cooling fiber structure composition, application number 101130584 publication number 201346084 a cooling and cooling fiber, preparation method and textile, application number 103102027 Bulletin No. / Certificate No. 1513808 has a low surface energy fiber manufacturing method, application number 100100655 bulletin number / certificate number 1437141 fiber with excellent humidity regulation performance and its application and manufacturing method, application number 098122940 bulletin number / certificate number 1374952 4T type The fiber and the spinneret and the method for producing the fiber of the 4T section, the application number 087117197 bulletin number/certificate No. 448254 anti-ultraviolet polyester composition and the fiber and cloth seed thereof.

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 multi-functional fiber which can have the advantages of ice-cold clothes, and to solve the six-required synthetic fiber and the composite yarn manufacturing method capable of absorbing sweat, heat resistance, coolness, quick-drying, gloss and ultraviolet resistance.

In view of the above, the present invention needs to develop a method for manufacturing a synthetic fiber composite yarn capable of solving the demand of summer apparel, and can provide a sweat absorption, heat resistance, cool feeling, quick drying, gloss, and resistance against the disadvantages of the prior art. A method for producing a multi-functional sheath-core fiber such as ultraviolet rays and a composite yarn thereof.

In order to achieve the above object, the present invention adopts the following technical solution: the patented invention utilizes three different yarns and is combined into a single composite yarn by a coating method.

There are three kinds of fibers in the three kinds of yarns, and there are four kinds of ingredients. There are also specific definitions of ingredients. The core-fiber method is used to combine the advantages of various fibers into a unique product. At the same time, it provides synthetic fibers with the characteristics of sweat absorption, heat resistance, coolness, quick-drying, luster, anti-ultraviolet, etc., and the composite yarns are processed by these three kinds of yarns.

One of the three yarns is an elastic material, which is an elastic fiber (known as OP in Taiwan, or PU in Japan, or Lycra or Spandex in Europe and America). According to ISO 2076 or DIN 60001, Elastan fibers are linear macromolecular synthetic fibers composed of a chained polyurethane of 85% by weight or more. It has strong elasticity and high stretch.

The three yarns are wound with elastic fibers by two other yarns, wherein the layer yarn is composed of nylon (Nylon) and polyethylene terephthalate (PET), and the nylon (Nylon) exhibits heat dissipation, coolness and speed. Dry. Polyethylene terephthalate fiber (PET) exhibits light blocking and heat insulation effects. The outer yarn is made of wood pulp and made of rayon fiber (Rayon), which has good water absorption, easy dyeing and excellent gloss.

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 following conventional disadvantages: it does not dry easily after a large amount of water is absorbed. 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 (Nylon) material to conform to the natural silk touch and cool feeling, but also avoids the problem that the nylon (Nylon) material is too soft. Therefore, polyethylene terephthalate fiber (PET) is added to give it a natural hemp stiffness. It has the dual advantages of polyester material and nylon (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. Rayon, a natural material, has a moisture wicking ability of 150% of natural cotton and is also suitable for spring and summer because of its touch and coldness.

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 fabric feels comfortable in the summer, far exceeding the 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:

1. Natural synthetic fiber and permanent function, which is not affected by time and detracts from its benefits

2. Both indoor cold, outdoor sunscreen, shiny texture, sweat absorption and quick drying, sweat absorption and cooling effects

3. Use Rayon's xylitol raw material source fiber to absorb sweat and cool down.

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

Figure 4 Nylon and PET composite yarn

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 sweat absorption Function cotton, viscous ray (Rayon), copper ammonium ruthenium (Rayon), 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 reinforce with PET 9; natural hemp 6 It has the advantages of breathability, water absorption and coolness, but it also has the disadvantage of being stiff and rough to the touch. It can be replaced by polyethylene terephthalate fiber (PET) 9, but it still has the disadvantages of sultry heat and no sweat absorption. It is necessary to use wood. Reinforced 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 hard drying. It can be replaced by wood fiber fiber ray (Rayon) 10 because it has water absorption and water release power. 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 advantages of natural silk 5, and the advantages of synthetic fiber, complement each other natural cotton 7, natural hemp 6 and natural silk 5 and polyethylene terephthalate (PET) 9, nylon (Nylon) 8 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. The sheath-core composite fiber of the present invention is of a concentric type. Such fibers can take advantage of the different properties of the various components to produce different morphologies and effects. The invention relates to a sheath-core composite fiber of PET 9 made of polyamide (nylon Nylon 8) and polyester fiber, mainly made of polyamide (nylon Nylon 8), polyethylene terephthalate fiber of polyester fiber. (PET) 9 is a core which combines the advantages of nylon (Nylon) 8 and polyethylene terephthalate (PET) 9.

There are three kinds of fibers in the three kinds of yarns, and there are four kinds of ingredients. There are also specific definitions of ingredients. The core-fiber method is used to combine the advantages of various fibers into a unique product. At the same time, it has one kind of synthetic fiber which simultaneously has the characteristics of sweat absorption, heat resistance, coolness, quick-drying, luster, anti-ultraviolet and the like, and the composite yarn is compounded by the three kinds of yarns.

One of the three yarns is an elastic yarn 11 which is an elastic fiber (known as OP in Taiwan, or PU in Japan, or Lycra or Spandex in Europe and America). According to ISO 2076 or DIN 60001, Elastan fibers are linear macromolecular synthetic fibers composed of a chained polyurethane of 85% by weight or more. It has strong elasticity and high stretch.

The three yarns are wound with elastic fibers by two other yarns, wherein the layer yarn is composed of nylon (Nylon) 8 and polyester fiber polyethylene terephthalate (PET) 9, which is heat-dissipated by nylon Nylon 8. Cool sensibility and quick drying. Polyethylene terephthalate fiber (PET) 9 exhibits light blocking and heat insulation effects. The outer yarn of the outer yarn is made of wood pulp, Rayon 10, which has good water absorption, easy dyeing and excellent gloss.

The first layer uses elastic material 11, the second layer uses nylon Nylon 8 and ethylene terephthalate fiber (PET) 9 composite, and the third layer uses wood pulp fiber Rayon 10 (rayon Viscos) The invention combines the characteristics of four kinds of fibers to synthesize yarn characteristics such as sweat absorption, heat resistance, coolness, quick-drying, gloss, and anti-ultraviolet.

Please refer to the fourth figure, especially the second layer: composite long-fiber (latitude) Nylon/ethylene terephthalate (PET) composite yarn 12, in which nylon (Nylon) 8 and terephthalic acid The ethylene glycol fiber (PET) 9 is compounded into the yarn, not the two separate fibers, but the two components are split and injected into the same yarn. The benefits of this split injection into the drawn yarn are:

1. Adding ore powder 91 or other coolant to the polyethylene terephthalate fiber (PET) 9 in the core layer during the manufacturing process, because the skin does not directly contact the ore powder, the touch is better and hindered. Light effect.

2. The ore powder is enclosed in the core layer and does not damage the needle of the weaving machine.

3. Helps with dyeing accuracy.

4. The skin layer of nylon (Nylon) 8 can be added with a high water content hydrophilic group 81 to smooth the surface.
