BACKGROUND ART For a long time, water-repellent processing has been applied to high-density fabrics using polyamide fibers or polyester fibers, and water-resistant fabrics have been known, and they are widely used in duck down jackets. Winter clothing, or windproof cloth, jackets, outerwear, sportswear and other sports clothing or outerwear. However, ordinary high-density fabrics have almost no elongation. Therefore, the movement of the body will be hindered during exercise, and they will feel oppressed, but they will not be able to move freely and feel uncomfortable. Because it is a high-density fabric, it feels harder. Furthermore, water repellency or resin processing to impart water resistance will increase the hardness of the fabric, so it will increase hardness and freedom of movement or body movements. The movements of the fabrics are hindered, and the frictional sound of the fabrics in contact with each other becomes large and uncomfortable. In order to solve these problems, Japanese Unexamined Patent Publication No. 1 1 — 8 1 1 4 1 discloses that weft and / or warp yarns of fabrics use polytrimethylene terephthalate fibers, and resin processing is applied to the fabrics. High-density fabric with soft feel. In Japanese Patent Application Laid-Open No. 11-200174, a poly (trimethylene terephthalate) having a ratio of the coverage of warp yarns and the coverage of weft yarns defined as the sum of the coverage ratios and an elastic recovery rate of more than 90% is disclosed. High-density fabric with soft texture made of fibers. However, the techniques disclosed in these publications are based on the formation of fabrics with soft poly (trimethylene terephthalate) fibers. The feel of the fabric or the friction between the fabrics is based on the Chinese National Standard (CNS) A4 specification (210 X 297).

To prevent the fabric from becoming thick and stiff, it should be less than 1 6 7 dte X. . The preferred fineness is 5 6 to 1 1 d t e X. The single yarn fineness should be 0 · 1 dte X or more in order to suppress yarn breakage during spinning and improve the stability of spinning. To maintain the water resistance of the fabric and suppress the rough feel, it should be 5 · 6 dt. ex or less. The preferred single yarn fineness is 0 · 56 ~ 3 · 3 dte X 〇 The cross-sectional shape of the polytrimethylene terephthalate fiber can be round, triangular, L, T, Y, W, There are many types, such as eight-leaf type, flat type, and dog-bone type. Those with edge shape, multi-leaf shape, hollow type, or indefinite shape can improve the stretchability, water resistance, and softness of touch of the fabric. It is preferable if the single yarn has a flat cross section. By adopting a flat cross-section yarn, flat single yarns in the fabric are overlapped and filled, which contributes to improvement of water resistance. In both cases, flat cross section yarns have significant bending resistance, so it is easy to buckle yarns orthogonal to flat cross section yarns in fabrics, and the elongation of crimps caused by the buckling of the flat cross section yarns is effective. By using it, the stretchability of the fabric is increased, and at the same time, it becomes a soft-feel fabric. The so-called flat cross-section here refers to the flat cross-section of a single yarn made of W-shaped, I-shaped, V-shaped, M-shaped, dog-bone-shaped, oval-shaped, wave-shaped, and sugar-cucurbit string-shaped.

The mixed fibers may be any type of fibers, polyester fibers, polyamide fibers, polyacrylonitrile fibers, polyethylene fibers, polypropylene fibers, polyurethane fibers, and other synthetic fibers. In the present invention, it is necessary to constitute warp yarns and / or weft yarns with polytrimethylene terephthalate fibers, but it may be interwoven with other fibers. As the interwoven fibers, synthetic fibers such as polyester fibers, polyamide fibers, polyacrylonitrile fibers, polypropylene fibers, and polyurethane fibers can be used. Moreover, the fabric structure is most suitable for plain fabrics, but it can also be satin fabrics, pattern fabrics, and multiple fabrics. The method of interweaving is to use polytrimethylene terephthalate fibers only in the warp or weft yarns, and use polytrimethylene terephthalate fibers and other fibers to combine the warp or weft yarns with one or two interactions. Intermixing methods and the like may be interlaced.

When the mixing ratio of the polytrimethylene terephthalate fiber is 35 weight% or more, it can be made into a material having good stretchability, water resistance, and hand feeling. The stretchable high-density fabric of the present invention has a cloth covering factor of 1 800 or more and 2 5 4 0 or less in order to obtain good stretchability, water resistance, and hand feel, and is preferably 19 0 0 to 2 3 3 0. In the high-density fabric of the present invention, the cover factor of the fabric is preferably one which is 10% or less lower than that of the general high-density fabric. The reason is that general high-density fabrics are oriented in order to improve water resistance and reduce the gap between yarns as much as possible. The fabric is woven into high-density at the stage of the fabric for processing. The high shrinkage treatment of the fabric is performed, and the width or length direction is added, and a special treatment is applied to make the gap between adjacent weaving yarns to make a high-density fabric. ...

In addition, to maintain the water resistance of the processed fabric and to impart elasticity on the surface of the fabric, such as wrinkles, creases, or texture weaves, it is preferable that the cloth surface coverage factor is 16 0 to 2 3 0. The high-density fabric of the present invention is characterized by a stretch ratio of 5 to 20% in the direction of the polyterephthalate fiber, preferably 7%. When the stretch rate is less than 5%, the body's movements during exercise are oppressed by hindrance, and it is not comfortable to move freely. If it exceeds 20, sufficient elongation can be obtained, but the flexion of the fiber becomes too fibrous. Roughness, increased thickness, and reduced water resistance are not suitable. In addition, the so-called expansion and contraction ratio is the use of katotex (strand) (LES-FB1).

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs on the present invention, as for the method for imparting elastic properties, in the weaving stage of the fabric, polyterephthalic acid generated by a weaving yarn orthogonal to the polytrimethylene terephthalate fiber The fine buckling (crimping) of the propylene glycol fiber is increased by a high shrinkage treatment such as hot water treatment, wet heat treatment, and dry heat treatment. This shrinkage imparts elasticity. That is, the crimping is obtained by increasing the density difference between the fabric density and the processing density of the fabric, and the fabric whose density has been roughly designed in advance is increased in density by high shrinkage treatment in the warp or weft direction. The shrinkage of the tissue caused by the shrinkage of the yarn itself, and the appearance of this paper are applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) -12- 1222473 A7 B7 V. Description of the invention (10) Orthogonal The warp (crimping) of the weaving yarn is increased and the winner is obtained. -------------- Packing --- «· (Please read the precautions on the back first and then 6 pages) Polytrimethylene terephthalate fiber Compared with polyethylene terephthalate fiber or polybutylene terephthalate fiber, which is a representative example of the fiber, the Young's coefficient of the fiber is smaller, so it has a very flexible and flexible characteristic. That is a major factor that causes tissue to shrink. By using this very flexible and flexible poly (trimethylene terephthalate) fiber, weft-to-warp yarns or warp-to-weft yarns can be fully flexed. If heat treatment is performed to increase the buckling shape, A weft or warp yarn is attached to a fabric in the form of a crimp caused by bending and buckling, and a high elongation can be exhibited by the contraction of the crimp. This high shrinkage treatment is to obtain sufficient stretchability, and it is appropriate to set the fabric density to increase the processing density by more than 10%. In addition, wrinkles or large weaves of the fabric may occur. In order to prevent the grade from falling, it is advisable to set the fabric density of the fabric to an increase in processing density of 40% or less. • Line · 〇Ministry of Economy Printed by the Consumer Cooperative of the Property Bureau for high shrinkage treatment methods, for example, to give elasticity in the weft direction, roughly design the warp yarn density, and use at least the weft yarn with a polytrimethylene terephthalate fiber fabric in the warp direction In the stretched state, the width is determined by heat treatment before or after refining, and a high shrinkage treatment is performed to give stretchability.

In the case of dry heat conditions, use a tenter that holds the cloth edge, and handle the mesh without a cloth belt. Drum processing and other equipment are performed, but in order to obtain the expected stretchability, a dry heat treatment machine using a pin tenter method that can control the dimensions in the warp and weft directions is suitable. The heat treatment temperature is It is advisable to perform sufficient shrinkage treatment to achieve the desired stretchability at 150 ° C or higher, and to prevent the strength from decreasing and the texture to become thick and hard, it is preferable to be below 200 ° C.- -In the case of hot water treatment, it is advisable to use a device such as a liquid flow dyeing machine with a large kneading effect. The treatment temperature is at a point where sufficient shrinkage treatment is performed to achieve the desired stretchability. Above 90 ° C, no special equipment is required and there is no productivity problem It is preferably below 140 ° C. In the case of hot water treatment, if the fabric or scoured fabric is directly treated with hot water, the sharp high shrinkage of silk and tissue will cause large beryllium patterns or folds. Before hot water treatment, it is better to pre-fix with lighter dry heat below 150 ° C. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, it is better to give flexibility. The high shrinkage treatment method, from the aspects of productivity, appearance quality, performance, etc., will use polytrimethylene terephthalate fiber fabrics on the weft yarns, using a pin plate tenter type dry heat treatment machine, It is decided to perform a dry heat treatment at 150 to 2 0 ° C in a state of a wide width of 10 to 40%, so that it is possible to perform scouring and dyeing processing after the weft yarn appears to be crimped. By using this method, The use of long-fiber raw yarn of polytrimethylene terephthalate fiber on the weft yarns also caused a large amount of shrinkage of the tissue, which can show a large number of weft yarn shrinkages. The paper size adopted on the weft yarns is subject to Chinese National Standard (CNS) A4 Specifications (210 X 297 mm) -1 4- 1222473 A7 B7 V. Description of the invention (14) The thickness (cm) is calculated by multiplying the area of Ιπί (1000crri). The fiber sufficiency of the fiber with the direction of stretchability, D s 値, is less than 0. At 5 o'clock, the stretchability will increase, but the water resistance will be slightly lower. If it exceeds 1.0, although the water resistance is good, the stretchability will not be sufficiently obtained, and the texture will tend to decrease. The more suitable range can be set by optimizing the covering factor of the fabric and the degree of shrinkage (crimping degree) of the structure of the fabric. In the present invention, it is a high-density fabric, and at the same time, it has a curling effect and a softness attributed to the Young's coefficient due to the poly (trimethylene terephthalate) fiber, and a moderate cloth cover factor, and a moderate fiber. Sufficient, with the expected stretchability and water resistance, it is possible to obtain a fabric that is soft and excellent in wearing comfort. Further, in the present invention, the water-repellent treatment such as water-repellent treatment or clogging of the obtained high-density fabric is carried out to maintain the aforementioned properties, and at the same time, a water-repellent fabric having good water repellency and water resistance can be obtained. The fabric to which this process has been applied is superior in wearing comfort such as two coats or sports windshields, and also has a low fuzz resistance (the ability to prevent the fluff material filled in the cold clothing material from being drawn from the surface of the substrate).

Description of the invention (2) Polytrimethylene terephthalate The false twisting of the fiber also suppresses the occurrence of creases caused by the excessive shrinkage of the false twisted yarn, which makes it possible to show a good weft curling caused by the shrinkage of the structure. In addition, the above-mentioned processing method makes it easy to manage scalability. Moreover, in the present invention, the scouring is a step for removing the spinning oil or warp yarn paste and the like attached to the woven fabric. As for the processing liquid used for this scouring, it contains water or a surfactant and alkali. An aqueous solution is preferred. The method for carrying out this scouring is not particularly limited, but in terms of fabric scouring, a commonly used open-type soaping machine type continuous scouring machine, liquid flow type dyeing machine, liquid sag type continuous scouring machine, rope It is better to treat the dyeing machine and soft scouring machine below 100 ° C. After the heat treatment and scouring, the dyeing and processing steps of the general processing steps are performed. In order to make the texture softer, alkali reduction processing may be performed before dyeing. In the present invention, c I 値, which indicates the shrinkage index of a fiber having a stretchable direction, must be greater than 0 · 0 0 5 in order to have sufficient stretchability. In order to prevent the surface of the fabric from becoming rough and rough, the friction sound is relatively low. The larger one must be set below 0. 1 13. The crimp index is a value calculated by dividing the crimp ratio (C R) of a fiber having a stretchable direction by the cloth coverage factor (C F v) of a fiber orthogonal to the fiber. The method of measuring the shrinkage rate is to place a 20 cm mark on the stretchable direction of the fabric (processed fabric), and then disassemble the fabric and take out the stretchable fiber in the direction of 0.9 g / dte. The load of X is to measure the length L (cm) between the marks at that time.
