Description

A rayon treat method of textile for manufacturing Acetate, a textile for manufacturing the rayon treat method}

FIELD OF THE INVENTION The present invention relates to rayonization of fabrics made of acetate, and in particular, to the fabrication made of acetate, which includes a mixture having a constant viscosity and is heat-treated to make it easy to rayon part or all. It relates to a rayonization method of a fabric, and a fabric produced thereby.

In general, Rayon fiber refers to regenerated fiber that has been evicted from trees. In some cases, fibrous chemical fibers such as viscose fibers, copper ammonia fibers and acetic acid fibers are collectively named. In a narrow sense, it refers to a viscose rayon belonging to the cellulose system among the regenerated man-made fibers, and is distinguished by filament and staple.

However, these rayon fibers had a problem that a lot of pollution occurs during the treatment.

Thus, a method of rayonating acetate has been proposed. Acetate could be used only as a disperse dye as a dye, and dyeing with a reactive direct dye was possible by rayonization.

In other words, this is the first wash the fabric made of acetate, put the fabric in the barrel with a certain ratio to the weight of the fabric, and after 3 hours of treatment at 100 ℃ or more, the soap 50 in the refined washing process When squeezed in water at ~ 200 ℃ for 120 minutes was able to obtain a rayon fabricated acetate.

In the required dyeing process, the reactive direct dye is added to dye one color to obtain a fabric.

However, such rayonization has a problem that it is not possible to selectively rayon a specific part by rayonizing the entire fabric.

In addition, since the process according to the rayonization has to be processed for about 3 hours in a space provided separately from the line, there is a problem that productivity is lowered.

Accordingly, the present invention has been made to solve the above problems, it is possible to simply rayon some or all of the fabric by heat treatment, including a mixture having a constant viscosity in the fabric prepared for acetate or acetate blends and heat treatment. It is an object of the present invention to provide a rayonization method of a fabric made of acetate.

Still another object is to provide a fabric which is partially or completely rayoned by coating and heat-treating a mixture having a constant viscosity on a fabric made of acetate.

Rayonization method of the fabric made of acetate of the present invention, the fabric produced by the present invention to achieve the above object, after washing the fabric using acetate, dyeing process and processing process such as drying and tendering, etc. In manufacturing the fabric with acetate, which is to be prepared through the material, the material which is compatible with a material of pH> 7.0 (hereinafter referred to as P) on the basis of the method of measuring the pH of the rayon material, that is, the aqueous solution before washing the fabric. A substance (hereinafter referred to as AP) mixed in a proportion of 0.1 <(weight of P ÷ A weight) x 100 <2,000 (hereinafter referred to as A) has a viscosity (hereinafter referred to as L) in a range of 300 <L <50,000 The material was obtained in the ratio of 0.01 <[weight of the AP attached to 1m 2 ÷ weight of g of 1m 2 of the fabric (g)] x 100 <500 on the fabric surface using the acetate (Di-Acetate) yarn. Apply to dry heat (T) or steam heat (T1) under 50 ℃ <T, T1 <250 ℃ It is prepared by heat treatment.

If pH <7 in the above, there is a lack of saponification (rayonization) of acetate.

When (weight of P ÷ A by weight) x 100 <0.1, the amount of P is so weak that the effect of this characteristic is insufficiently expressed.

On the other hand, if (weight of P ÷ A weight) × 100> 2,000, rayonization is clearly expressed, but AP may remain in baths and fabrics during scouring and dyeing processes and stains may occur, and staining color reproducibility may be poor.

In addition, if L <300, it is difficult to apply the AP to the fabric, and the AP may be unevenly spread on the fabric surface and absorbed into the fabric unevenly, causing color stains and the like.

In addition, if L> 50,000, the workability of the process of attaching the AP to the fabric may be poor, and the productivity may be poor. Also, the AP may be unevenly applied, and the color stain and shape may not be clearly displayed.

In addition, if [weight of AP attached to fabric 1㎡ ÷ weight of fabric 1㎡ (g)] × 100 <0.01, partial shapes and spots may be expressed on the fabric surface very weakly. It is not enough to express the characteristics of anger.

In the case of> 500, the fabric characteristics of the present invention may be sufficiently expressed, but the manufacturing cost increases, and the AP remains in the scouring and dyeing processes, resulting in poor color reproducibility and quality reproducibility.

On the other hand, if T, T1 <50 ° C, the manufacturing cost increases due to the long heat treatment time, and also uneven drying of the AP may cause dyed stains.

In addition, when T, T1> 250 ° C., a thermosetting phenomenon occurs in the fabric, which may result in poor quality of hard touch.

On the other hand, the (weight of P ÷ A of weight) × 100 is '10' when the fabric is examined as a result of the repeated experiments, L is '5,500', [weight (g) ÷ fabric of the AP attached to the fabric 1㎡ Weight (g) of 1 m &lt; 2 &gt;] is applied at a ratio of '17' and it is judged that an optimum state can be obtained when heat-treated at 120 캜.

Hereinafter, an embodiment according to rayonization of a fabric made of acetate according to the present invention will be described.

Example 1

In Example 1, a cellulose fiber cloth and soda ash (Na2co3) were mixed at a weight ratio of 10:70, and a mixture having a viscosity of 6,000 was mixed with a diacetate and a polyester material. 12% of (g) was applied to the fabric in each of the embossing process, the coating process, and the printing process, followed by processing at dry heat 150 ° C. and steam heat 120 ° C., respectively.

As a result, only the color and quality characteristics of acetate and polyester were expressed before the treatment, but after this process, new fabrics capable of expressing the color and quality characteristics of acetate, polyester, and rayon were prepared.

Example 2

In Example 2, a polyester fiber cloth and a soda ash (Na2co3) were mixed at a weight ratio of 15:65, and a mixture having a viscosity of 7,000 was mixed with a diacetate and nylon material. % Is attached to fabric in the tendering process, drying process, laminating process, and foiling process, and then processed at dry heat 140 ℃ and steam heat 110 ℃ respectively. It was.

As a result, only the color and quality characteristics of acetate and nylon were expressed before the treatment, but after this process, a fabric capable of expressing the color and quality characteristics of acetate, nylon and rayon was obtained.

In other words, the fabrics were previously rinsed in a batch or continuous manner by putting the fabric in water at 50 ° C to 250 ° C and then dyed / processed such as coating, embossing, tendering, drying, printing, and foiling. In the manufacturing process, the mixture of the present invention (AP) using the apparatus used for each coating, embossing, tendering, drying, printing, foiling, etc. used in the dyeing / processing process before the scouring washing process After the coating, the rayonization is achieved by drying at 50 ° C to 250 ° C.

At this time, the fabric of the acetate or acetate mixture can be dyed only with a disperse dye, and the rayonized portion will only be a reactive direct dye to enable the expression of various colors.

Therefore, by applying the apparatus used in the processing process the mixture (AP) to the fabric, it is possible to selectively rayon a specific portion to the fabric and to rayon the whole.

That is, it is possible to form a variety of rayonized specific patterns using the coating and processing devices such as embossing and printing.

Accordingly, the rayonization of the fabric is simplified, and the productivity can be improved by being applied in the fabrication line. On the other hand, when extracting the rayon fiber from the tree as in the prior art, the acetate is put into a batch container and the alkali solution is released to release the rayon. There is less pollution / waste than toxic waste, so there is little pollution problem.

As described above, the rayon is simply rayonized to some or all of the fabrics in the quality characteristics of the acetate and acetate mixtures by coating and heat-treating the mixture (AP) having a constant viscosity on the fabrics prepared for the acetate or acetate mixture. It can also express the quality characteristics of the rayon has an effect that can respond to the needs of various consumers.

On the other hand, although described based on the preferred embodiment of the present invention, those skilled in the art can be variously modified and changed within the scope of the invention without departing from the spirit and technical means of the present invention.
