Description

  The present invention relates to a woven fabric and a processed product of the woven fabric. More specifically, the present invention relates to a cover such as a building material cover, a sheet such as a waterproof sheet, a woven fabric used as a sheet-like material such as a tent, a packaging bag, and a flexible container, and a woven fabric processed product thereof.

Conventionally, a sheet-like woven fabric is produced by weaving a bundle of fibers in which multifilaments are converged, and in order to weave, a surface adhesion treatment of an oil agent (antistatic agent) on the multifilament, Twisting was essential. However, when twisting is performed, the fiber bundles in the woven fabric tend to be uneven, and as a result, it has been difficult to obtain a woven fabric having good physical properties, particularly strong tensile strength and low elongation.
In addition, when the waterproof function is imparted to the woven fabric, the surface of the woven fabric is subjected to water repellency treatment. The waterproof woven fabric thus obtained can absorb water between single fibers, There is a problem that moisture permeates into the end face and the damaged part of the glass.

  Therefore, in order to cope with such a problem, for example, a base fabric made of polyethylene terephthalate (PET) fiber using a fluorine-based water repellent as a spinning oil (see, for example, Patent Document 1) or a tarpaulin base fabric is configured. Disposing water repellent treatment on the surface of each multifilament, such as treating a fiber bundle composed of polyester fibers to be treated with an emulsion mainly composed of a fluorine-based water repellent and a polyester-based urethane (for example, see Patent Document 2). Has been.

However, in these cases, the number of treatment agents and the number of processes increases, the cost increases, the problem of the woven fabric remains as it is, and the weave obtained by the water-repellent treatment of fibers and fiber bundles. The fabric (texture) is disturbed, and the quality and appearance of the product deteriorate.
Further, a resin-coated processed cloth in which at least one surface of the waterproof woven cloth is coated with a resin has been proposed (see, for example, Patent Document 1). This gazette discloses that an effect is exerted on a base fabric having a coarse structure in which stitch misalignment and string yarn are used to prevent misalignment so as not to cause misalignment. On the other hand, since the adhesiveness between the woven fabric on the water-repellent surface and the coating resin is lowered, the adhesiveness is maintained only when the upper and lower coating resins are fused with each other in the gap of the coarse texture. It is inferred. In this case, it is conceivable that the processed fabric is not integrated and the processed product of the waterproof woven fabric having high physical properties is difficult to obtain.

  According to the present invention, a woven fabric having good physical properties such as high strength and low elongation, and maintaining good physical properties, and having good waterproof properties, and processed woven fabrics thereof at low cost. Can be provided.

The woven fabric of the present invention is a fiber-reinforced thermoplastic resin obtained by stretching a converged sheath-core type composite spun fiber at a temperature not lower than the melting point of the sheath component and lower than the melting point of the core component, and fusing the sheath component. It was produced using a linear body.
As the core component (high melting point component) in the sheath-core type composite spun fiber, crystalline propylene polymer, crystalline polyester such as polyethylene terephthalate and polybutylene terephthalate, polyamide (nylon), aromatic polyester resin (liquid crystal polymer) Etc.), and these may be used alone or in combination of two or more. Among these, in consideration of recyclability and the like, when the sheath component described later is a polyolefin resin, a crystalline propylene polymer which is the same kind of polyolefin resin is preferable.

  As this crystalline propylene polymer, an isotactic polypropylene resin is preferably used. Among them, those having an isotactic pentad fraction (IPF) of preferably 85% or more, more preferably 90% or more are advantageous. The Q value (weight average molecular weight / number average molecular weight Mw / Mn ratio), which is an index of molecular weight distribution, is 6 or less, and the melt index MI (temperature 230 ° C., load 2.16 kg) ranges from 3 to 50 g / 10 min. preferable. If the IPF is less than 85%, the stereoregularity is insufficient and the crystallinity is low, and the physical properties such as strength in the obtained linear body are inferior.

The isotactic pentad fraction (IPF) (generally also referred to as mmmm fraction) is a side chain with respect to the main chain of carbon-carbon bonds composed of any five consecutive propylene units. This shows the proportion of the three-dimensional structure in which two methyl groups are located in the same direction. Pmmmm (5 propylene units are isotactic) in the isotope carbon nuclear magnetic resonance spectrum ( ¹³ C-NMR). From the absorption intensity derived from the methyl group of the third unit at the bonded site and Pw (absorption intensity derived from all methyl groups of the propylene unit), the formula IPF (%) = (Pmmmm / Pw) × 100
Can be obtained.

The polypropylene resin may be a propylene homopolymer or a copolymer of propylene and an α-olefin (for example, ethylene, butene-1, etc.).
That is, as the crystalline propylene polymer, for example, isotactic propylene homopolymer having crystallinity, ethylene-propylene random copolymer having a small ethylene unit content, homo-part consisting of propylene homopolymer and ethylene unit A propylene block copolymer composed of a copolymer part composed of an ethylene-propylene random copolymer having a relatively large content, and each homo part or copolymer part in the propylene block copolymer further comprises a butene- Examples thereof include crystalline propylene-ethylene-α-olefin copolymers formed by copolymerizing α-olefin such as 1.

On the other hand, as the sheath component (low melting point component), a thermoplastic resin having a melting point lower by 20 ° C. or more than the melting point of the core component is used. Examples of such thermoplastic resins include various olefin polymers and low melting point polyethylene terephthalate. Examples of the olefin polymer include ethylene polymers such as high density, medium density, low density polyethylene and linear low density polyethylene, copolymers of propylene and other α-olefins, specifically propylene. Examples thereof include a -butene-1 random copolymer, a propylene-ethylene-butene-1 random copolymer, an amorphous propylene-based polymer such as soft polypropylene, and poly-4-methylpentene-1. One of these olefin polymers may be used alone, or two or more thereof may be used in combination.
In particular, it is preferable that the core component is polypropylene and the sheath component is polyethylene because it is inexpensive.

The sheath-core type composite spun fiber used in the present invention is composed of the core component and the sheath component covering the core component, and the production method is not particularly limited. Conventionally, the sheath-core type composite spun fiber is used. The well-known method currently used in manufacture of can be used. For example, by using the above-mentioned sheath component and core component, and melt spinning at a spinning temperature of about 200 to 260 ° C. by a composite spinning apparatus equipped with two extruders and a sheath core type fiber nozzle, a composite with a sheath core structure is obtained. A spun fiber is obtained.
The core / sheath cross-sectional area ratio in the sheath-core type composite spun fiber thus obtained is usually selected in the range of 40/60 to 80/20.

In the present invention, the sheath-core type composite spun fiber is converged in a straight form without being twisted, and stretched at a temperature not lower than the melting point of the sheath component and lower than the melting point of the core component. The components are fused to produce a fiber reinforced thermoplastic resin linear body.
The stretching method may be any method as long as a desired fiber-reinforced thermoplastic resin linear body can be obtained, and is not particularly limited. However, the sheath-core composite spun fiber is stretched in pressurized saturated steam. It is preferable because a fiber-reinforced thermoplastic resin linear body having good physical properties can be obtained.
In the present invention, a preliminary stretching treatment may be performed as desired before performing the stretching treatment in pressurized saturated steam.

  In this preliminary drawing step, the composite spun fiber is drawn at a temperature lower than the drawing temperature in the subsequent main drawing step. As this pre-stretching treatment method, for example, generally known contact heating stretching using a metal heating roll or a metal heating plate, or heated fluid such as warm water, steam of normal pressure to 0.2 MPa or hot air, A method such as non-contact heating stretching using heat rays such as far infrared rays can be applied. Furthermore, it is also possible to perform a preliminary stretching treatment at a temperature lower than the stretching temperature in the main stretching step by the same system as the high-pressure steam stretching tank used in the main stretching step.

As the draw ratio in this pre-stretching step, a range of 25 to 90% of the total draw ratio including the main stretching process is suitable, and the stretching conditions may be appropriately selected depending on the system of the pre-stretching apparatus, the stretching state, and the like. . In particular, in the case of two-stage stretching in which the main stretching process is performed after the preliminary stretching process is performed in one stage, the preliminary stretching ratio is preferably in the range of 25 to 85% of the total stretching ratio, and more preferably in the range of 35 to 80%. preferable. Further, the preliminary stretching treatment may be performed in one stage, or may be performed in multiple stages of two or more stages. In the case of performing in multiple stages, the stretching temperature is constant and the preliminary stretching ratio is multistage. The method and the method of making a draw ratio multistage, giving a gradient to extending | stretching temperature can be used.
On the other hand, the present drawing step is performed by applying pressurized presaturated steam having a temperature not lower than the melting point of the sheath component and lower than the melting point of the core component to the pre-stretched product of the composite spun fiber or the composite spun fiber obtained in the above-described pre-stretching step. This is a step of directly heating and performing the main stretching treatment.
The main draw ratio is appropriately selected according to the fineness of the composite spun fiber or its pre-drawn product, but is usually selected so that the total draw ratio is 5 to 20 times, preferably 7 to 17 times.

Preferably, the maximum diameter is 15 μm to 40 μm.

The fiber-reinforced thermoplastic resin linear body is produced by drawing a plurality of unstretched composite fiber yarns while being bundled, and the number of fibers to be bundled is preferably 20 to 500. If the number is less than 20, the composite yarn single fiber may become thick and the spinnability may be deteriorated. If the number exceeds 500, the spinning nozzle density increases and the composite single fiber becomes thin and both the spinnability and stretchability deteriorate. There is a risk. More preferably, it is 100-300. The tensile strength is usually preferably 4 cN / dTex or more, but is generally in the range of 4 to 12 cN / dTex. Furthermore, the elongation is usually in the range of about 5 to 30%, preferably 10 to 25%, more preferably 15 to 20%.
