[Field of Application of the Invention] The present invention relates to a desizing and scouring method that enables continuous and rapid desizing and scouring of natural cellulose fiber fabrics and fabrics containing natural cellulose fibers. [Background of the Invention] Conventional continuous desizing scouring of natural cellulose fiber fabrics and fabrics containing natural cellulose fibers includes a steaming method or a normal pressure treatment method in which submerged treatment is performed after steaming, but these methods have low Since the amount of water required for the solubility ratio and for the drug to act quickly is insufficient, a larger amount of the drug than necessary and a longer processing time are required. For example, even if you perform submerged treatment after steaming, which requires 45 to 60 minutes of processing time using 5 to 10% caustic soda and 1 to 2% oxidized desizing agent based on the weight of the fabric, the processing time is just enough to correct the unevenness of the steaming process. Not much can be expected to be achieved in shortening the process, and scouring wrinkles and unevenness occur especially in high-density fabrics, so at present, rapid continuous desizing scouring using a high-pressure steamer is often used for high-density fabrics. In other words, in conventional normal pressure processing methods (equipment), fabrics are folded or loaded in order to compensate for the lack of moisture, ensuring a long processing time, which naturally lacks the speed of processing. In addition, uneven heat distribution tends to occur due to folding of the fabric, and furthermore, there is a problem that uneven reaction due to chemicals occurs. In order to correct these processing irregularities, excessive chemicals are used and processing time becomes longer. The above problems are unlikely to occur with low-density fabrics, but with high-density fabrics, the chemical action on the folded and flat areas does not proceed uniformly, resulting in wrinkles and uneven scouring, which can cause problems during dyeing in the subsequent process. Cause. In order to quickly achieve the desizing and scouring effect with a small amount of chemicals, it is necessary to uniformly treat the fabric with a melting ratio that exceeds the adhesion limit, and conventional methods cannot treat the fabric with a water content that exceeds the adhesion limit. Even if you forcibly add a lot of water, liquid will drip during loading, resulting in uneven processing. [Object of the Invention] The present invention has been made in view of the above, and provides a desizing method for fabrics that can perform continuous and rapid desizing scouring under normal pressure without particularly using a high-pressure steamer. The purpose is to provide a method of refinement. That is, to describe the present invention specifically, when a natural cellulose fiber and a fabric containing natural cellulose fiber are continuously desized and refined, acid treatment, oxidizing agent treatment, alkali treatment, and desizing treatment are performed in the order of suspension state (loop state). ). Therefore, according to this treatment method, since the fabric is treated in a liquid without folding it, sufficient humidity and heat energy can be uniformly applied to the fabric, so that no uneven treatment is observed. Furthermore, the amount of chemicals used is smaller than in conventional methods, and uniform desizing and scouring can be achieved. [Embodiments of the Invention] Examples of the present invention will be specifically described below. A high-density fabric of 40×40/134×110 was used as the fabric to be treated, and this fabric was first heated at about 95°C in a dilute acid aqueous solution with a hydrogen ion concentration of PH 2 to 3. It is immersed in an unmatted state for about 5 seconds while being transported by guide rolls to be acid-treated. Then,
The fabric is treated with an oxidizing agent by immersing it in a hot solution of hydrogen peroxide at about 95°C for about 20 to 50 seconds in the same unwrapped state. Next, the fabric is immersed in a heated solution of caustic soda at about 95°C for about 20 to 50 seconds in the same unwrapped state for alkali treatment. Next, the fabric was soaked in a heated solution of ammonia persulfate at about 95°C for about 20 to 50 minutes in the same unfolded state.
It is immersed for a second to perform desizing treatment, thereby completing a series of treatments. In this way, in this example, the processing steps are performed in the order of dilute acid treatment, oxidizing agent treatment, alkali treatment, and desizing treatment, compared to the conventional process of desizing treatment, alkali treatment, and oxidizing agent treatment. When compared with the above, it can be seen that the desizing effect of this example is high as shown below. Next, to specifically explain the effects of this example, oxidizing agent treatment (35% hydrogen peroxide 5 c.c./solution) - alkali treatment (caustic soda 5 g/solution) - desizing treatment (ammonium persulfate 2 g/solution) ), and when the solutions were boiled to about 95°C and treated for about 30 seconds each, the measured suction value was 40 mm in about 10 minutes, but as in this example, when the solution was boiled at about 95°C, the measured value was 40 mm. By acid treatment in hot liquid for about 5 seconds, the measured value on the wicking side increased to 70 mm in about 10 minutes, which shows that the initial acid treatment effect is high. When the oxidizing agent was treated with hot water for 30 seconds with acid activity of 25% sodium chlorite 2 c.c./c., the wicking length was 65 mm without dilute acid treatment, but before hot water with pH 2 to 3. After treatment, the suction length becomes 70mm. The effectiveness of acid treatment increases significantly from 40mm to 70mm in the case of hydrogen peroxide. Sodium chlorite has a small rise range of 65mm to 70mm. In the case of sodium chlorite, since the treatment liquid is acidic, the acid treatment effect is also exhibited at the same time, so when using sodium chlorite, the acid treatment can be omitted. Even if acid treatment lowers the pH to 2 or less,
Furthermore, even if the processing time was extended to 30 seconds, there was no change in the effect.
The preferred condition for the PH2-3 treatment time is about 5 seconds. Acids used for pH adjustment include organic acids such as formic acid, acetic acid, and oxalic acid, and inorganic acids such as hydrochloric acid, nitric acid, sulfuric acid, and phosphoric acid. The influence of the desizing scouring effect due to changes in processing order is compared by 30 seconds of hot liquid treatment and wicking length (10 minutes). (However, the test fabric is a fabric that has been acid-treated for 5 seconds in a hot liquid with pH 2 to 3) Oxidizing agent treatment → Alkali treatment → Desizing treatment Wicking length 70mm Desizing treatment → Oxidizing agent treatment → Alkali treatment Wicking Length 60mm Oxidizing agent treatment → Desizing treatment → Alkali treatment Wicking length 60mm Alkali treatment → Oxidizing agent treatment → Desizing treatment Wicking length 60mm Desizing treatment → Alkali treatment → Oxidizing agent treatment Wicking length 45mm Alkali treatment → Desizing treatment → Oxidizing agent treatment The suction length was 40mm. Fabrics processed in the order of oxidizing agent treatment, alkali treatment, and desizing treatment have the most desizing and refining effects. The oxidizing agents after dilute acid treatment include peroxide-based oxidizing agents such as hydrogen peroxide, sodium peroxide, sodium perborate, potassium permanganate, and peracetic acid, as well as calcium hypochlorite and hypochlorous acid. Chlorine-containing oxidizing agents such as soda and sodium chlorite. And the amount used is 0.05 to 0.2% solution in solid terms, 95
Preferably, the treatment is carried out for 20 to 50 seconds at temperatures between ℃ and boiling. When treated with an oxidizing agent before the alkaline treatment, the fat content of natural cellulose becomes easily soluble and the saponification effect of the alkali is promoted, so that scouring can proceed quickly with a low concentration of caustic soda. There is no difference in effectiveness even if 0.2% or more of the oxidizing agent is used, so there is no need to use a large amount. The effect can be achieved in just 50 seconds. The fabric treated with the oxidizing agent is saponified with the following alkaline solution. Caustic soda as an alkali agent
Boil at 95°C for 20 to 50 seconds with a 0.3-0.5% solution. Even if you multiply it by 0.5% and the processing time is 50 seconds or more, there is no big difference. If desizing is performed after alkali treatment, desizing will be faster. In addition, unsaponified fat content is also saponified and removed by the desizing treatment, which further enhances the effect and provides a satisfactorily desizing scouring fabric. The desizing agent used is peroxo monosulfate, peroxo disulfate, sodium bromite, or a commercially available oxidized desizing agent. The amount used is preferably a 0.1% to 0.3% solution. The processing conditions are
