Description

[0001] The present invention relates to a fabric and a method of fabricating a polyester twisted fabric for embossing, and a method of fabricating the same to produce a jacquard fabric effect by embossing.

The present invention relates to a method for embossing a polyester filament, comprising the steps of: embossing a polyester filament by selectively twisting a portion of a fabric woven by twisting and selectively heat treating the filament in consideration of a design, and then subjecting the portion to a heat treatment, The present invention relates to a method of fabricating a fabric and a method of fabricating the fabric, which is characterized by forming irregular irregularities only in a portion of the design motif that has not been formed, thereby showing a natural jacquard effect.

Conventional jacquard fabrics are used to show the design by using the heald in weaving, which requires a lot of production cost and low productivity. In addition, a general embossing fabric refers to a processing that forms a three-dimensional embossing by embossing / embossing by heat and pressure when the embossing roller is pressed on a engraved embossing roller with a set of embossing / embossing up and down embossing / embossing, thereby exhibiting a natural jacquard fabric effect and design as in the present invention I can not.

In order to solve the above problems, the present development is not to weave jacquard fabrics using existing healds, but to lower costs. It is not to form the design by merely three-dimensional effect of engraving / embossing through the design embossing process on the woven fabric by twisting the polyester filament using the water storage housing so that the effect of the jacquard surface is improved with high productivity. The purpose of this study is to develop a fabric and a processing method that can express the design by using the difference of the deformation of the fabric base floor and show the natural jacquard fabric effect.

In order to accomplish the above object, the present invention provides a method for fabricating a polyester filament, comprising the steps of: twisting a polyester filament water storage bin and weaving the same in plain weave; performing a design embossing process for selectively heat treating the fabric in order to develop a jacquard fabric effect and design; A scouring and shrinking step for forming irregular irregularities to form a three-dimensional texture, a pre-setting step for fixing the jacquard fabric effect of irregular three-dimensional protrusions and protrusions protruding from the convex convexes, a weight reducing treatment step for imparting a touch, a dyeing and post-finishing step .

The purpose of this development is to develop a fabric and a processing method which express a design so that the effect of jacquard fabric on the surface is low while having a low cost and high productivity, and a natural design is expressed differently from the existing jacquard fabric.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, a method of fabricating a jacquard fabric according to a preferred embodiment of the present invention includes a weaving process S1000, a design embossing process S2000, a scaling down process S3000, a presetting process S4000, Processing (S5000), dyeing (S6000), and post-processing (S7000).

In the weaving step (S1000), the warp yarns 11 are twisted in a rightward direction with a polyester filament water storage yarn having a fineness of 30 denier to 300 denier by 3000 to 300 yarn counts (T / M: unit length, Processing (continuous shooting). Or a polyester filament yarn having a fineness of 30 denier to 300 denier is used. The weft yarn 12 is twisted leftward by twisting yarns of 30 denier to 300 denier polyester filament water for 3000-300 years (T / M: unit length, twist number given to 1 meter). A polyester filament having a fineness of 30 denier to 300 denier is wound on the warp yarn 11 by twisting the warp yarn in the right direction with 3000-300 years of running (T / M: unit length, twist number given to 1 meter) The weft yarns 12 are alternately crossed one by one to weave the fabric into the plain weave fabric 13 or alternately cross the polyester filament yarn and the weft yarn 12 of the yarn fineness of 30 denier to 300 denier to the plain weave 13 The fabric is woven to prepare the raw material support 23.
The polyester filament low shrinkage yarn used in the present invention has a heat shrinkage of 5% or less in the refining and shrinking step of 80 to 130 degrees, and the shrinkage ratio of polyester filament yarn is 7 to 15%.

The life supporting unit 23 that has been woven (S1000) is subjected to a design embossing process (S2000).

In the design embossing process S2000, the raw support 23 is sandwiched between the design embossing roller 21 and the planar roller 22, which are formed with a desired design, and is driven in the roller driving direction 24 while being pressed at high temperature. And proceeds to the direction (25).

The embossing roller 21 is heated at a temperature of 150 to 220 deg., And the engraved roller 31 is not subjected to heat treatment because it is not in contact with the life support part 23 as a motive part of the design. Only the portion of the surface 32 of the embossing roller 21 which is the ground portion of the design is brought into contact with the raw material support 23 and is glossed by the action of heat and pressure and the thermoplastic polyester yarn is permanently fixed, Respectively.

The design embossed fabric 26 is subjected to refining and reducing (S3000).

The scaling down (S3000) uses a liquid scaling unit, the scaling down temperature is between 80 and 130 degrees, and the treatment time is between 20 and 60 minutes.

The volume and length are increased as the twisting process of the polyester yarn is solved through the smelting process in the smoothing and reducing process (S3000) only the portion 28 that has not been heat-treated in the design embossed fabric 26. Since the heat shrinkage of the low shrinkage yarn is less than 5%, the bulky shrinkage yarn which forms a bulge forms a loop and protrudes convexly between the crossing points of the warp yarns to form irregular irregularities to form a three-dimensional texture on the bottom of the fabric. All of the warp and weft yarns were woven using twisted polyester filament water storage housing. Irregular irregularities appeared in all directions in the radial direction, and the fabrics woven using twisted polyester filament water storage yarns only in weft yarns, Irregular irregularities appear only in the direction.
The portion 27 subjected to the heat treatment in the embossed fabric 26 has gloss and is thermally fixed due to the thermoplastic nature of the polyester yarn to control the grain and shrinkage so that it remains smooth as it is. Only the part of the irregular three-dimensional texture of irregularities. Therefore, a three-dimensional design is formed due to irregular irregularities and differentiation of luster, and a jacquard effect is exhibited.

The raw fabric that has undergone refining downsizing (S3000) stabilizes the shape of the three-dimensional fabric through the presetting (S4000), fixes the standard, maintains the design effect molded at the subsequent stage, I decide.

Pre-setting (S4000) is done in Tente, a cloth dry heat treatment machine, at a temperature of 180 degrees to 220 degrees, and the treatment time is 30 seconds to 180 seconds.

After finishing the pre-setting (S4000), the cloth is subjected to a weight reduction process using caustic soda (S5000) for soft touch and then to dyeing (S6000).

In the dyeing step (S6000), the heat-treated portion 27 shows luster and the untreated portion 28 has a distinctive luster. It has the same effect as jacquard fabric.

After the dyeing step (S6000), the fabric is subjected to a post-processing step (S7000) in which drying and heat treatment are performed at a temperature of 120 to 220 degrees for 30 to 180 seconds.
