JPH09254335A - Base fabric for indicator label and its manufacture - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a base fabric for indicator label and its manufacture wherein drape and nerve are firm, printing can be carried out at a high speed, and these is neither shrinkage nor deformation against heat. SOLUTION: In a base fabric for indicator label having a porous layer of a nylon resin on base fabric woven cloth, the base fabric woven cloth is woven fabric wherein a core sheath type composite mutifilament of a polyester as the core and a nylon as the sheath is made warp and/or weft. For its manufacture, a coating material in which a nylon resin is dissolved in a methanol solution is applied onto the base fabric woven cloth wherein the core component is the polyester, the sheath component is the nylon, and a core sheath type composite mutifilament yarn in which 10 or more pieces/m of entanglements are formed are woven as warp and/or weft without sizing, which is solidified by removing the solvent by being dipped in water. Then, a porous layer of the nylon resin is formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base cloth which is printed and used as a quality display label attached to clothes, bedding, sundries, and the like.

[0002]

2. Description of the Related Art Clothes, bedding, miscellaneous goods, etc. are attached with a label indicating the manufacturer, quality, handling precautions and the like. Conventionally, as these display labels, a label cloth on which a porous layer of nylon resin is formed on a woven fabric by a well-known wet film-forming method and the items to be displayed are printed is often used. As the woven fabric for the above-mentioned display label, for example, a nylon cloth is disclosed in JP-B-57-6115, a polyester cloth is disclosed in JP-A-4-265987, and a warp is cotton in JP-B-62-36232. Fabrics using nylon as the weft are disclosed, respectively.

[0003]

However, nylon fabrics have low dimensional stability because they swell when applied with a paint using a polar solvent such as water or methanol, and the paint application process and the subsequent printing process. Problems such as easy occurrence of defective products in the process, difficulty in speeding up printing because the fabric is too soft, and warping of the ears due to heat shrinkage when cutting with a rotary heat cutter lowers productivity and quality. I'm holding.

In the case of polyester cloth, the above-mentioned problems do not occur, but the adhesiveness with the nylon paint is not good, so that it is necessary to add the step of applying the polyester paint, leaving the problem that it takes time and effort. There is.

Therefore, the present invention has an object to provide a base fabric for a display label which is firm and firm and capable of speeding up printing, and which does not shrink or deform even with heat, and a method for producing the same. There is.

[0006]

In order to solve the above problems, the present invention has the following constitution. That is, the display label of the present invention is a display label base fabric having a porous layer of nylon resin on the base fabric, wherein the base fabric is a core-sheath composite multi-layer having a polyester core and a nylon sheath. It is characterized by being a woven fabric in which filament yarns are used as warp yarns and / or weft yarns.
A core-sheath type composite multifilament yarn in which entangles of m or more are formed is warped and / or without sizing.
Alternatively, a base fabric woven as a weft is coated with a coating in which a nylon resin is dissolved in a methanol solution of calcium chloride, which is immersed in water for solvent removal and coagulation to form a nylon resin porous layer. Made of

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below. In the present invention, the polyester component used as the core component of the core-sheath type composite multifilament yarn includes ethylene terephthalate unit or ethylene terephthalate unit, isophthalic acid, adipic acid, sebacic acid, 1,4
It is preferable to copolymerize a component selected from butanediol, 1,6-hexanediol, diethylene glycol, polyethylene glycol and the like in a proportion of 50 mol% or less.

The nylon component used as the sheath component of the core-sheath type composite multifilament yarn is preferably 6-nylon or 66-nylon, but is not particularly limited.

The core / sheath composite multifilament yarn has a core / sheath volume ratio of 5/1 to 1/5, particularly 3/1 to 1
/ 2 is preferable. The cross-sectional shape of the composite filament yarn may be any of a circle, an ellipse, a polygon, a star, and the like, and the core and the sheath may be arranged concentrically or eccentrically. It is preferable to use a circular shape in which the core and the sheath are concentrically arranged.

The core-sheath type composite multifilament yarn used in the present invention preferably forms 10 or more entangles. With less than 10 entangles / m,
Fuzz and the like are likely to occur during weaving, which may reduce productivity and quality of the base fabric, which is not preferable. Further, in the present invention, it is preferable not to perform the sizing which is usually performed before weaving the woven fabric. Sizing is not preferable because it becomes less compatible with the nylon coating used in the wet film forming method.

In the method for producing the base fabric for display labels of the present invention, the nylon component of the coating material applied by the wet film forming method is 6-nylon, 66-nylon or the same resin as the sheath component of the core-sheath type composite multifilament yarn. It is preferably used, but it is not particularly limited.

[0012]

EXAMPLES The present invention will be specifically described below with reference to examples. A core-sheath composite multifilament yarn (75d / 24f, entangled number 32 / m) having a core / sheath volume ratio of 1/1, with polyethylene terephthalate as the core and 6-nylon as the sheath, without warping As a weft, a plain weave (a) having a warp / weft density of 111/85 per inch was woven. As a comparative sample, regular 6-nylon multifilament yarn (70d / 1
8f, entangle number 16 / m) was used as warp and weft without sizing, and a plain weave (b) having a warp / weft density of 111/85 per inch was woven. The strength, elongation and boiling water shrinkage of the filament yarn used are shown in Table 1.

[0013]

[Table 1]

On the plain woven fabrics (a) and (b), a known wet film-forming method is applied to solidify a porous layer of nylon resin, and two kinds of base fabrics for display labels (A) and ( B)
I got

Three kinds of quality indicating marks are printed on the surfaces of the base fabrics (A) and (B) obtained above, and further cut into a certain size by a rotary heat cutter to obtain two kinds of quality indicating labels. Got

From the results of the above examples, the dimensional stability of the base cloth (B) is low when it is brought into contact with methanol or water in the nylon coating in the step of forming the porous layer by the wet film forming method. Therefore, it is difficult to increase the productivity, and it is difficult to speed up the printing process because the base fabric itself is soft, and deformation is likely to occur during cutting, and the yield is 90% or less. On the other hand, for the base cloth (A), since polyester is used as the core component of the core-sheath type composite yarn, the base cloth itself is firm and firm, and the dimensional stability against methanol and water in the nylon paint is high. It is also excellent in resistance to heat and deformation, has good ink placement in the printing process, can be sped up, and has a yield of 100%.

[0017]

As is clear from the above results, the display label for quality and the like obtained by the present invention has little deformation and firmness and firmness, and its manufacturing method is stable and efficient, It is clear that it is highly practical.
