The present invention relates generally to a breathable fabric structure, and more particularly to an improved structure of breathable opaque fabric with thick and thin feeling, which is formed by the reciprocal arrangement of different composite processing yarns and the weft density strip number variation in sequence.
In recent years, the situation of global warming has gradually intensified. Taiwan has island-type climate; in summer, it is difficult to endure that the climate is humid and hot. It is particularly necessary to make clothes with air permeability and moisture absorption and sweating effect. Therefore, how to make clothes with the effect of keeping dry, refreshing, air permeability moisture absorption and sweating in the cost range has become the problems that need to be solved urgently by the manufacturers.
At present, most of the existing clothes are woven by plain weaving, and the warp and weft are woven vertically and horizontally to form a cross-staggered appearance with the same density, so that the flatness can be presented. In this way, although the structure is tight, the free distance of the warp and weft is extremely small, and often occurs when the user is sultry and unable to breathe, causing the user to sweat when the user wears the clothes on the body, and the cloth adheres to the skin to cause discomfort; therefore, relevant industry researchers have developed a breathable fabric structure, which is woven by using a plurality of warp yarns and corresponding weft yarns, wherein an intermediate yarn is added between two warp yarns and two weft yarns, so that each intermediate yarn is respectively interlaced across at least three yarn lengths, and the intermediate yarns are long and easy to be shrunk, so that both the warp yarns and the weft yarns on both sides are closed inwards to the intermediate yarn. In order to define an air vent in the middle and to produce an air permeable effect, but due to the formation of pores in the middle of the yarn, the woven fabric may be translucent and euphotic. Because the warp yarns and the weft yarns on both sides are closed inwards to the middle yarn, the time and labor are required for finishing and weaving, which will increase the production cost.
There are also related manufacturers that have developed a fabric with a hollow hole structure. The polyester fiber and the elastic fiber are mainly sprayed by an air jet nozzle, and two or more warp yarns are twisted to form a fabric structure with several variations around a plurality of weft yarns by using a weaving method, and the warp yarns are arranged in a cross-displacement cross-over design to form hollow holes of different sizes, so that they are elastic and breathable, but the production process is complicated and relatively three-dimensional, and it is impossible to form a flat fabric.
Further, the related manufacturers have developed the structure of the cool-feeling skin core type fiber and its composite yarn containing different components, which are mainly composed of three different fibers such as elastic fiber, skin core type fiber and rayon. The single composite yarn is then interlaced by a specific yarn weave or a unique warp and weft to achieve the multiple cool feeling function, such as sweat absorption, heat resistance, cool feeling, quick-drying, luster, anti-UV, etc., but the shortcomings of the different materials cannot be exposed at the same time, and the fibers of different compositions falsely twisted into a single composite yarn will greatly reduce the loss in the process and time.
Therefore, how to use chemical fiber raw materials for producing the breathable opaque fabric in the cost range through different design methods, so as to reduce the material cost and shorten the process, which has become an important problem to be solved by the inventor of this case.
Therefore, the inventor carefully studies the creative spirit of the invention. Based on the above technical issues, the inventor starts the research and development. Based on professional creative experience for many years and practical experience, the inventor carefully research and develop new ideas, and then proposes this invention, so as to improve the advantages and disadvantages of the present invention of this product.
The main object of the present invention is to provide a composite processing yarn formed by two different common fibers, and by means of interactive arrangement and weft density variation, a thick and thin breathable opaque woven fabric is formed to reduce the cost and improve production efficiency while achieving the effect of shortening the process.
Another object of the present invention is mainly to provide an improvement in manufacturing design to substantially reduce the material cost by adjusting the ratio and process and to produce an improved structure of breathable opaque fabric with thick and thin feeling.
Another object of the present invention is to provide a fabric with a breathable effect by adjusting the manufacturing design structure, and also, the light transmittance is low and the skin is not easily translucent, and the production cost can be greatly reduced to obtain the same effect, thereby effectively improving the product competitiveness in the industry.
In order to achieve the above objects, the improved structure of breathable opaque fabric with thick and thin feeling in the present invention is a fabric mainly composed of warp and weft yarn, wherein the warp yarn and the weft yarn are composed of the polyester fiber and elastic fiber, which are alternately arranged and combined by the warp composite processing yarn and the weft composite processing yarn are. Wherein, the warp composite processing yarn and the weft composite processing yarn comprise an arranged combination of two or more processing yarns with different linear density proportions, and the two warp composite yarns with different proportions are alternately arranged, and then two weft composite yarns with different linear density proportions are arranged with different numbers to form a dense arrangement, and then the woven fabrics are subject to dyeing and boiling water processing to form a flat fabric with thick and thin difference.
Preferably, the warp composite processing yarn and the weft composite processing yarn are formed by composite processing of polyester fiber and elastic fiber.
Preferably, the warp composite processing yarn comprises the composite processing yarns of the polyester fibers and elastic fibers arranged in a sequence of 150D/40D and 70D/40D, and the weft composite processing yarn comprises the composite processing yarns of the polyester fiber and the elastic fiber arranged in sequence with 150D/40D per 75 strips and 70D/40D per 70 strips.
Therefore, with the present invention, the improved structure of breathable opaque fabric with thick and thin feeling can have a breathable effect and an excellent effect to avoid the light transmission, and also shorten the process and reduce the cost and the special material expenditure, described as follows:
(1) By combining the different fibers with a specific ratio, the composite processing yarns can be especially breathable through the layout design, thereby achieving cost reduction and also having the same effect.
(2) Through the general polyester fiber combined with elastic fiber in a specific ratio of composite processing, it retains the characteristics of different fibers, and uses the proportional weft density variation weave, so that the fabric can have both cool, heat and UV resistance, greatly improving product competitiveness.
(3) The present invention uses the composite processing yarns with different proportions to design through a specific proportion of weft density variation, so that the fabric can be breathable by dyeing and finishing the boiling water to achieve a breathable effect and a flat fabric, hereby reducing the complicated processing process and avoiding the shrinkage.
(4) By means of different composite processing yarns with a specific ratio, the flat fabrics can be produced directly by weaving and dyeing and finishing in the weft density variation and warp density arrangement way, which can greatly reduce the manpower in machine finishing weaving, and shorten the process and reduce the cost.
