Abstract

PROBLEM TO BE SOLVED: To provide a method for producing a high-density woven fabric having excellent tear strength and waterproofness. SOLUTION: A multifilament consisting of synthetic fine filaments having a single yarn fineness of 0.5d or less is used for the warp and the weft, and the ripstop constituting the lattice is configured to have a total fineness more than twice as large as the ground yarn. When inserting, weaving is performed by dividing the ripstop portion with reed feathers, inserting the ripstop portion more than the number of ground yarns, weaving, and performing water repellent treatment and calendering.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a waterproof high-density fabric having excellent tear strength.

[0002]

2. Description of the Related Art Conventionally, sports clothing such as ski, marine, and athletic has been required to have both functions of moisture permeability and waterproofness. In addition, the strength of the greige is required for use in the field.

In general, in order to meet these requirements, a method of forming a microporous resin layer on the surface of a water-repellent cloth by a coating method, a laminating method, or the like using a polyurethane resin or a polyamino acid resin, etc. A method of applying a water-repellent treatment to a woven fabric obtained by weaving ultrafine fibers at a high density has been performed. In addition, a method of subjecting a high-density woven fabric to a water-repellent treatment and further subjecting the woven fabric to heat and pressure treatment with a heating calender or the like to crush the mesh of the woven fabric is performed. Further, in order to increase the tear strength, a method of making the tissue ripstop has been used.

[0004] However, the waterproof cloth obtained by these methods has a problem that in the former case, the feeling becomes hard and the tear strength decreases, and in the latter case, water leaks from the ripstop portion. , There is a problem that sufficient water pressure cannot be obtained.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and has as its object to provide a method for producing a high-density woven fabric having excellent tear strength and high water pressure resistance. Things.

[0006]

Means for Solving the Problems The present inventors have conducted intensive studies to solve such problems, and as a result, when weaving a high-density woven fabric, the fineness of the single yarn used and the pull-in at the time of reed insertion. Having found the fact that the method is important, we arrived at the present invention. That is, in the present invention, the single yarn fineness is 0.5
Using a synthetic fiber ultra-fine multifilament yarn of denier or less for the warp and weft, the rip-stop part forming the lattice pattern is composed of two or more ground yarns, and the warp of the rip-stop part is inserted into the reed when inserting the reed. The present invention provides a method for producing a high-density woven fabric, characterized in that weaving is performed by inserting more rip-stop portions than the number of ground yarns and weaving, and then performing water-repellent treatment and calendering treatment. .

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.
In the present invention, it is necessary to use an ultrafine fiber having a single yarn fineness of 0.5 d or less. When weaving a high-density water-resistant fabric, it is necessary to make the fabric surface finer, and it is effective to use ultra-fine fibers. It becomes easier to obtain a high water-resistant fabric. The texture of high-density woven fabrics tends to be hard, and if a heat calendering process is performed in the finishing process, the texture becomes even harder. The use of microfibers is necessary in the present invention.

Further, the woven fabric according to the present invention comprises
This is a ripstop woven fabric in which a lattice pattern is formed by aligning more than one book. The ripstop part that forms this lattice pattern
It is composed of two or more ground yarns.
It consists of five. Further, the ripstop may be a so-called double ripstop in which two or more aligned portions are continuously arranged or one to several ground structures are interposed therebetween.

In the present invention, the warp constituting the rip-stop portion is divided by the reed feathers when inserting the reed in preparation for weaving.
In addition, it is necessary to insert the rip-stop portion more than the number of ground yarns to prepare.

Conventionally, when fabrics are manufactured with a ripstop structure, when two fabrics are aligned and inserted into a reed, the ripstop portion is divided by the reed as shown in FIG. A method of inserting the same number of pieces at a time or increasing the number of pieces inserted at the ripstop portion as shown in FIG. 5 is used. These are intended to eliminate the difference in the warp tension during weaving and improve the weaving property. However,
From the viewpoint of water resistance, the ripstop portion and the ground structure have strictly different densities, the ripstop portion is rough, and a space is created at the boundary between the ripstop portion and the ground structure. Leakage occurs. Normally, in the case of three-line alignment, a method of inserting the rip-stop portion into the same reed dent as shown in FIG. 6 to increase the number is used. Also in this case, the water resistance is lowered for the same reason as described above.

From these facts, the present inventors have found that it is important to increase the density of the rip-stop portion and the ground structure at the boundary between the ripstop portion and the ground structure portion. That is, as shown in FIGS. 1 to 3, the rip-stop portion is divided by a reed, and the weaving is performed by inserting the rip-stop portion more than the number of ground yarns inserted. As a result, the density at the boundary between the ripstop portion and the ground structure is higher than that of other ground structures, the ripstop portion is further densified, and water leakage is prevented. In Fig. 1, the ground structure (the warp is indicated by ■) is a flat structure, and two ground yarns are aligned and the ripstop portion (the warp is represented by ●).
(Indicated by) is shown, and shows the state of insertion into the corresponding reed dent below the organization chart. In the leftmost reed in FIG. 1, three ground yarns and one of the two warp yarns in the ripstop portion are inserted, and a total of four yarns are inserted in the right reed. The number of inserts in the ground organization department is three.

In the present invention, the woven fabric woven as described above is sequentially subjected to a water-repellent treatment and a calendering treatment. As the water repellent used in the water repellent treatment, a known water repellent such as a silicon compound or a fluorine compound may be used, but from the viewpoint of the water repellency and washing durability of polyester synthetic fibers. A fluorine-based water repellent is preferably used. Further, a melamine-based, imine-based, or isocyanate-based cross-linking agent may be used in combination in order to increase the water-repellent washing durability. Further, an antistatic agent for suppressing the generation of static electricity or various finishing agents for providing functionality by other auxiliary processing may be used in combination. The water-repellent treatment is performed by a conventional method in which a water-repellent solution is applied to a fabric by a padding method, a spray method, a dipping method, or the like, followed by drying and heat treatment. The adhesion amount of the water repellent, the drying conditions, and the heat treatment conditions may be appropriately determined depending on the water repellent used, the product application, and the like, and are not particularly limited in the present invention.

The calendering process densifies the fabric structure,
This is performed to improve the water pressure resistance, and is performed by a method in which a woven fabric is passed between a pressurized hot steel roll and a paper roll. Normal processing conditions are heating temperature 130
To 190 ° C., a calender pressure of 5 to 100 kg / cm 2 , and a speed of 1 to 30 m / min. In the calendering process, the back of the fabric comes into contact with a hot steel roll, It is preferable to carry out calendering so that the surface contacts the paper roll surface.
