CN1616729A - Lining cloth - Google Patents

Abstract

The present invention relates to a liner cloth satisfying necessary conditions as the liner cloth, further having good feeling, and hardly causing fraying of thread. The liner cloth is obtained by weaving the cloth by using a core-sheath type conjugate yarn having a high-viscosity polyester resin as the core part and a low-melting point crystalline polyester resin as the sheath part as one of the weft or warp yarns in an proportion of 50-100%. The core-sheath conjugate yarn is on the market, for example, as a name of Melset(R)from Unitika Fibers Ltd. Any yarns can be used as the other yarns as far as the yarns do not go against the object. The core-sheath conjugate multifilament can be used as the yarns but, in that case, the proportion is preferably 10-60%. The fabric density of the liner cloth is preferably 10-150 yarns/inch in each of warp and weft directions, and the textile weave is preferably plain weave.

Description

Liner cloth

Technical field

When the present invention relates to batch the half finished rubber sheet, bonding in order not make between the sheet rubber, between sheet rubber, insert and the liner cloth of use.

Background technology

As such liner cloth, can know from the technology that for example following patent documentation 1 is put down in writing.As described in this communique, usually, be necessary to possess following characteristic as liner cloth.

(1) only use under the situation of sheet rubber and peeling off of half finished rubber sheet wanted easily from the liner cloth that is involved in the half finished rubber sheet.

(2) the unilateral adherence of half finished rubber that contacts with liner cloth is reduced.

(3) batch in the operation that wrinkle are difficult to produce and to batch operation good.

(4) for using repeatedly, good endurance, and cheap.

(5) flexible little, DIMENSIONAL STABILITY is good.

Patent documentation 1: special fair 1-60569 communique

In patent documentation 1, for this purpose, having proposed by the fusing point difference is the compound of the fiber that constitutes of at least 2 kinds of component of polymer more than 30 ℃ or fabric that blend constitutes, by constituting the fusion of the low melting point polymer composition in the fiber, the liner cloth that the crosspoint of the warp that constitutes fabric and parallel is being melted.

Summary of the invention

The present invention desires the purpose that reaches identical by method for distinguishing.

Liner cloth of the present invention is characterized in that, on warp and/or parallel, use 50～100% in core configuration high-viscosity polyester resin, dispose the core sheath recombination line of low-melting crystalline polyester resin and be made in sheath portion.

The liner cloth that obtains according to the present invention fully satisfies the necessary condition as above-mentioned liner cloth.And then liquor style is good, is difficult to separate line.Further, liner cloth of the present invention has passed through the machine operation makes cloth stable, thereby can omit the heat setting operation.

The specific embodiment

As an example of ", disposing the core sheath recombination line of low-melting crystalline polyester resin in sheath portion " in core configuration high-viscosity polyester resin, like that the core sheath of structure compound long fine in No. the 3304020th, patent, be known.About constituting the polyester of sheath portion, record in same communique [0009], put down in writing in same communique [0007] [0008] about the mylar that constitutes core, the pass of core and sheath portion ties up to record in [0010], about putting down in writing in [0011] [0012] for the concrete grammar that obtains composite fibre.In the concrete finished product that uses with the fiber of the invention of communique, can enumerate " retractility bondedfibre fabric, the furniture that is used for the upper mask of patch agent base fabric, paper nappy is continuous with filling, bed, automotive seats with mat or cotton-padded mattress, mattress, mat etc. " ([0005]).

In addition, the long fibre that such core sheath is compound, for example Unitika Corp (ユ ニ チ カ Off ア イ バ one strain formula people's commune) (Unitika Fiber Co., Ltd) with Mai Ersaite (メ Le セ Star ト) (Melset) title of (registration mark of same company) on market, sell.The fusing point of the core of Mai Ersaite is 250 ℃, and the fusing point of sheath portion is 160 ℃.

The physical characteristic of the representational line of Mai Ersaite is as described below.

Mai Ersaite is aforesaid long fine, but in the present invention except that it, also can use the short fiber line as core sheath recombination line.That is, only long fine line, any one of only short fiber line, or the combination of long fine line and short fiber line can.

Among the present invention, use 50～100% above-mentioned core sheath recombination line and be made into a side of warp and parallel.Preferred especially 100% uses.

About other line, only otherwise opposite with above-mentioned purpose, can be for arbitrarily.For example, can use the synthetic line of the natural fabric line, nylon, polypropylene etc. of silk floss, silk, wool etc.Also can use above-mentioned core sheath recombination line here, if but use above-mentioned core sheath compound long fine two sides of warp and parallel near 100% ground, then owing to really up to the mark and be unsuitable as liner cloth.If use, then be preferably 10～60%.

The density of knitting of liner cloth of the present invention is that longitude and latitude all is preferably 10～150 pieces/inch, is preferably 20～50, and fabric tissue can use that plain weave is knitted, twill weave, crowfoot satin, and wherein preferred plain weave is knitted.

In addition, make the liner cloth of formation in the above described manner pass through the processing of hot-working further (heat setting) sclerosis, if calender is processed and the fissility of rubber just improves more for further generation flatness applies.

The width of liner cloth is generally about 130～170cm, but there is no need to use in the overall with scope cloth material of the present invention, only uses at both ends and just can.For example, can only use the liner cloth material of the present invention of 5～10cm at both ends.

Below, enumerate embodiment and specifically describe the present invention.
