Abstract

PURPOSE:To prevent removal of fibers such as wool or feather by padding cotton cloth for side cloth of FUTON woven in a coarse density and in a larger width than the standard with an alkali solution and steaming. CONSTITUTION:Cotton cloth for side cloth of FUTON obtained by arranging 40/-cotton combed yarn as warp and weft and weaving the combed yarn in a coarse density and in a larger width than the standard into 2/2 twill texture is subjected to given singeing, desizing, scouring, bleaching and dried. Then the cotton cloth is padded with an alkali solution containing 50-55g/l caustic soda, squeezed at 50-60 % squeezing ratio and steamed at 100-103 deg.C for 1-1.5 minutes to give cotton cloth for side cloth of FUTON having a contracted width and <=2cm<3>/cm<3>/second air permeability. The cotton cloth for side cloth of FUTON has no luster with glitter by wear, no hardening of appearance physical properties such as shrinkage percentage and improved durability.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing futon side fabrics which can prevent cotton from slipping off wool and feathers used as futon cotton.

[0002]

2. Description of the Related Art The futon side, which has been used to store wool and feathers inside, has been calendered under high-pressure and high-temperature conditions for bleached, dyed or printed fabrics to prevent cotton loss. However, in this case, calendering causes a glossy luster on the side surface and the texture becomes paper-like and hard, and the thread deformed by calendering is the original when washed. There was a problem that the shape returned to its original shape and the breathability increased, and the durability of the cotton drop prevention property deteriorated.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has good luster and texture with good cotton-pulling-out preventing property and durability without calendering the cotton fabric. The purpose is to obtain a futon side ground without hardening.

[0004]

The present invention achieves the above-mentioned object and has the following configuration. That is, according to the present invention, a cloth of 100% cotton woven with a coarse density and a width wider than a specified width is pad-steamed with an alkaline solution to shrink the width of the cloth and to have an air permeability of 2 cm ³ /
The gist is a method for processing futon-sided material, which is characterized by controlling to less than cm ² / sec.

The present invention will be described in detail below. The cotton 1
The number of warp yarns of 00% fabric is the same as that of high-density fabric, but by weaving the fabric wider than specified, the density becomes coarse, and the width of the fabric is increased by pad steaming with an alkaline solution in the processing process. It shrinks and closes the gap between the warp and weft to prevent cotton loss such as wool and feathers.
In particular, in the present invention, in the processing step, after the usual desizing, scouring and bleaching, the cloth width is contracted by pad steaming with an alkaline solution so that the air permeability is suppressed to 2 cm ³ / cm ² / sec or less. It is a thing.

Examples of the alkaline solution used in the present invention include aqueous solutions of sodium hydroxide, potassium hydroxide, lithium hydroxide and the like. In particular, sodium hydroxide is preferably used in terms of its effect and cost. In the case of sodium hydroxide, the concentration of the alkaline solution is preferably about 50 to 55 g / liter. The drawing ratio may be 55 to 60%. Steaming is performed at 100-103 ° C for 1-1.5 minutes.

The machine used for pad steaming of the alkaline solution in the present invention is effectively a pad steamer or a single mangle and atmospheric steamer. The cloth that has been shrunk by steaming can maintain its shrunk width even in the subsequent process, the warp and weft threads become dense, and the air permeability is controlled to ² cm ³ / cm ² / sec or less, and cotton such as wool and feathers is controlled. It is prevented from coming off.

[0008]

[Function] As in the present invention, when the alkaline liquid is pad-steamed on the cloth of 100% cotton which is coarsely woven and whose width is wider than the specified width, the width of the cloth is contracted and the air permeability is 2 cm ^3.
/ Cm ² / sec or less can be controlled, which allows wool without high temperature and high pressure calendering.
It is possible to obtain the effect of preventing the cotton from falling out. Also,
It does not have the luster and texture hardening that occurs with calendering, the physical properties are stable, and the durability is improved.

[0009]

[Examples] Examples of the present invention will be described in detail below. The performances of the examples were evaluated by the following methods. (1) Preventing cotton slipping A 50 cm square bag is formed both vertically and horizontally using a work cloth, and down 50% down / feather 50% down 13
Enclose 0 g, and quilt and fix the center line at the position of 25 cm from each end in a cross shape to make a sample. This sample 1
20cm x 40cm pillow (the contents are pushed in as much as the raw cotton is inserted)
Two of them were put in a tumbler dryer, and they were operated at room temperature at a speed of 40 times / minute and inverted for every 10 rotations for 3 hours. With respect to this sample, the blowout of the feather was visually inspected with respect to a 10 cm × 10 cm square part which was 3 cm from the sample end and the center line, and when 0 to 1 in this range, it passed, and 2 or more. When it was rejected. (2) Air Permeability Measured by JISL-1096 (Flagille's method) for samples after processing and after washing once. The washing test was conducted according to JIS L-1096 (method 103). (3) Shrinkage rate The sample after processing was measured by the JISL-1042D method. (4) Feeling The handling test was used to make a relative evaluation in the following three stages. ○: Good, △: Normal, ×: Hard

Example 1 The futon side material has a texture design in which combed yarn 40 /-is used for the warp and combed yarn 40 /-is used for the weft.
A 2/2 twill woven with a book / inch and a weft of 130 / inch, and this fabric was processed by the following procedure. That is, the dough was subjected to a normal method of singing (on one surface side) -desizing / scouring-bleaching-drying, and then pad steam of alkaline solution-soaping-drying. Among these processing steps, pad steam is performed at 8 ° Baume at 100 ° C for 1 minute, soaping is performed at 80 ° C for 1.5 minutes with 2 g / l of a surfactant, and drying is performed at 100 ° C for 1 minute. It went on condition of. The obtained futon side fabric had a warp density of 148 yarns / inch and a weft density of 130 yarns / inch.

Comparative Example 1 For the purpose of comparison with the present invention, the same yarn usage, weaving density, and weaving texture as the futon side fabric obtained in this Example 1 were prepared, and the same as in Example 1 was prepared. By method, singe (front side) -de-sizing
After each step of scouring-bleaching-drying, 160k at 120 ℃
Calendering was performed twice under the condition of g / cm ² . This is the conventional method for processing futon side land.

The performances of the present invention and the comparative work cloth were evaluated, and the results are shown together in Table 1.

[0013]

[Table 1]

Comparing Example 1 and Comparative Example 1 above, in Example 1, the alkaline steaming step using pad steam is required, but the calendering process (twice) as in Comparative Example 1 is not necessary, and As is clear from Table 1, the texture is good, the change in air permeability due to washing is small, and the durability is very good.

[0015]

Industrial Applicability According to the present invention, the cloth of 100% cotton, which is woven with a coarse density and a width wider than the specified width, is pad-steamed with an alkaline solution to shrink the width of the cloth and to have an air permeability of 2 cm ³ / It has a control structure below cm ² / sec,
According to the present invention having such a configuration, it is possible to obtain the effect of preventing cotton loss of wool, feathers and the like without performing calendering at high temperature and high pressure. In addition, it eliminates the glossiness and hardening of the texture that is caused by calendering,
The shrinkage rate and physical properties are stable, and the durability is also improved.
