Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method of applying a wrinkle pattern to a cellulose fiber fabric.

(Prior Art) Various treatments for adding wrinkles to cellulose fiber fabrics have been conventionally performed. For example, a physical method of adding wrinkles by applying physical pressure under dry or warm conditions, a method of applying wrinkles after processing, a method of applying alkali treatment at low concentration and high temperature for a long time or a high concentration and low temperature for a short time, and fibers. There is a resin processing method that uses elementary reaction resin and performs creasing and heat treatment after padding.

However, with such conventional methods, the durability of wrinkles is only about a few times of washing.

Therefore, methods for manufacturing fabrics with various wrinkle patterns have been studied instead of wrinkled processing.
Japanese Patent Laid-Open No. 5915582 discloses a method in which the fabric is bundled into a rope shape and/or crimped and dyed at the same time or immediately after this to create a wrinkled pattern. is Mgl11 in three-dimensional shape
When applying dyes and pigments to objects by padding and/or coating methods, the knitted fabric is
A method has been proposed in which a wrinkle pattern is created by padding and/or coating with an overlap of 5 to 75%.

(Problem B to be solved by the invention) However, the methods of JP-A-48-96887 and JP-A-59-15582 apply the dye in a wrinkled state during dyeing, so the dye is partially applied. not dyed,
This has the disadvantage that blank areas may remain.

That is, in the conventional wrinkle pattern processing methods, there was no method other than the printing method that could produce a wrinkle pattern in which areas without wrinkle patterns were uniformly dyed.

The present invention was made in view of the above-mentioned problems, and an object of the present invention is to provide an hour wheel and an efficient method for manufacturing a cellulose-based fabric having a wrinkle pattern in which the wrinkle-free portion is uniformly dyed. It is something to do.

(Means for Solving the Problems) In order to achieve the above object, the present invention has the following configuration. That is, in the first invention, a cellulose fiber fabric is subjected to wrinkle processing, and then the surface of the fabric is raised, and 100 g
/ The gist of the invention is a method for processing a cellulose fiber fabric with a wrinkle pattern, which is characterized by carrying out an alkali treatment with one or more aqueous alkaline solutions and then dyeing it, and the second invention is a method for processing a cellulose fiber fabric into a wrinkle pattern, which is characterized by carrying out an alkali treatment with one or more alkaline aqueous solutions and then dyeing. After applying embossing, the surface of the fabric was raised and 100g/W
The gist of this invention is a method for processing a cellulose fiber fabric into a wrinkled pattern, which is characterized by carrying out an alkali treatment with the above aqueous alkali solution and then dyeing it.

The present invention will be explained in detail below.

Cellulose fibers used in the present invention include cotton linen, rayon, acetate, etc., but cotton is the most preferred from the viewpoints of inventive effect, utility value, and alkali resistance. Cellulose fibers may be used alone or in combination with other fibers by blending, knitting or weaving, and in the case of mixed use, it is desirable to contain 50% by weight or more of cellulose fibers. Examples of the fabric include fabrics, fabrics, non-woven fabrics, and the like.

After performing pre-treatments such as burning, desizing, scouring, bleaching, etc. on the fabric in the usual manner, the wrinkles described below are sequentially processed by processing, raising, alkali treatment, dyeing or embossing, raising, alkali treatment, and dyeing. give

Wrinkling as referred to in the present invention can be achieved by methods such as applying physical pressure to give it a shape, for example, using devices such as a mangle, a fulling machine, a washer processing machine, or by folding cellulose fiber fabric. There are methods such as folding it and applying pressure to hold it.

Embossing using an embossing roll as referred to in the present invention is an embossing calendar processing machine that rotates an embossing roll (metal heated roll with engravings) and a pair of konoton or paper poles while pressing them together with an appropriate pressure. Examples include those carried out by introducing a fabric between an embossing roll and a cotton or paper ball. Embossing can be carried out at a temperature and pressure that maintains its shape, usually at a temperature of 150-200°C and a pressure of 100-200°C.
It is preferable to carry out the test under the condition of "1000 kg/am".

The wrinkled or embossed fabric is then raised, and the raising method may be by using a cloth needle, raising with emery paper sand cloth, etc., or a combination of both. Further, the length of the raised fluff may be adjusted by jarring or the like.

Next, an alkaline aqueous solution is applied to the raised fabric by spraying, padding, etc. to perform an alkali treatment, a so-called mercerization treatment. In the present invention, the alkali is
Sodium hydroxide, potassium hydroxide, lithium hydroxide,
Although rubidium hydroxide, cesium hydroxide, etc. can be used, it is common to use sodium hydroxide. The concentration of alkaline aqueous solution is 100 g/j! Above, preferably 100 to 350 g/7! If the concentration is less than 100 g71, a dyed product with insufficient colorability and wrinkle pattern can be obtained. The temperature of the aqueous solution is preferably 45°C or lower,
A range of 0 to 40°C is more preferable. The fabric to which the aqueous alkali solution has been applied is subjected to tension treatment if necessary, and then the alkali is removed from the fabric by washing with water using a shower, an open soaper, a winch, or the like. If it is difficult to remove by washing with water, an acid such as hydrochloric acid, sulfuric acid, or acetic acid at an appropriate concentration may be used as an alkali removing agent.

The alkali-treated fabric is then dyed by any of the commonly used dyeing methods for cellulosic tlA'll. However, as a dyeing method,
In the case of the exhaust dyeing method using the hatch method, if the dyeing time is too long, the entire dye may be uniformly dyed and the wrinkle pattern effect may be reduced, so a continuous dyeing method is preferable.

(Function) Since the present invention is constructed as described above, the sharply angled wrinkles caused by processing or embossing are strongly raised by the next raising process, and the fiber surface is damaged in this strongly raised part. This allows the alkali to penetrate easily, resulting in an alkali-treated fabric with strong wrinkles. By dyeing the fabric in this state, a product with a wrinkled pattern in which the wrinkled portions are dyed in a dark color can be obtained.

(Example) Next, the present invention will be specifically explained based on Examples.

Example 1 In this example, a cellulose-based fiber fabric having a warp density of 108 threads/inch and a weft density of 58 threads/inch, consisting of a #20 single yarn in the warp and a single yarn #20 in the weft, was used. .

After pre-treating the fabric by conventional methods such as burning, desizing, scouring, and bleaching, the fabric was bundled under a pressure of 100 kg.
