ばならない。(Prior Art) Conventional mercerization of long cotton knit fabrics that are industrially produced and processed includes, for example, gray mercerization in which the top knit is treated using a caustic soda solution of 22°Be' to 27°Be'; There is post-mercerization, which involves scouring and bleaching the fabric and then processing it.These mercerizations involve soaking a given cotton knit fabric in a caustic soda solution at 22°Be' to 27°Be', and then mercerizing the fabric. The fabric is transferred while being tensioned in the width direction by a tenter (width direction tensioning device), and during this transfer, washing water is showered onto the fabric on the tenter to wash it.Next, the fabric is removed from the tenter and left under free tension. Matsuta (high temperature cleaning equipment)
The fabric is passed through a water washing device, an acid neutralization tank, a water washing device, and a drying device in order to perform each treatment, and finally the treated fabric is finished to a predetermined width to form a product. That is, the rising width of mercerized cloth according to the conventional method is about 70% of that of raw silk cloth. Normally, the finished width of the final product is about 85% of the raw knitted fabric, so 100X 85/70412.1, ie, mercerized fabric, must be expanded by about 12% to obtain a product of a predetermined width.

性の高いシルケット加工布帛を得ることができる。(Means for Solving the Problems) The present invention has been made in view of the above, and in order to obtain a cotton knit fabric with low heat shrinkage and excellent dimensional stability, a fabric to be mercerized is treated with caustic soda. Treatment, hot water washing, and acid neutralization are performed in this order. During the caustic soda treatment and acid neutralization, the fabric is stretched in the width direction, and during the hot water washing, This process is performed without tension, and as a result, it is possible to obtain a mercerized fabric with high dimensional stability, which is the desired objective.

布帛は、処理完了されて次処理工程へと運ばれる。Reference numeral 1 denotes a knit fabric to be processed, and this fabric 1 first passes through a fabric spreading device 2 and a texture correction device 3, where it is subjected to predetermined spreading and texture correction, and then passes through a group of selvage prevention rollers 11 to a pinning device 4. will be introduced in By this pinning device 4, the pin is held between the endless first pin tenters 5 and transferred under tension. This pin tenter 5
The fabric 1 transferred under tension is guided by guide rolls 12 and immersed under tension in a caustic solution tank 6 to be impregnated with the desired caustic solution, and then separated from the caustic solution tank 6 and transferred under tension into the air. The timing is processed inside. After this timing has elapsed, the fabric 1 is separated from the pin tenter 5 by the separation roll 7, and only the fabric 1 is supplied into the hot water washing tank 8, where it is subjected to a hot water washing process without any tension. The fabric 1 is again suppressed from selvage by the selvage prevention roll group 9 and is supplied to the pinning device 13, where it is held by the endless second pin tenter 14 and transported under tension. The fabric 1 transferred under tension by the pin tenter 5 is guided by guide rolls 15, and is supplied under tension into an acid neutralization tank 16, where it is neutralized. After this neutralization treatment, the fabric is separated from the second pin tenter 14 by the separation roll 17 and placed in a tensionless state in the washing tank 1.
8. The fabric washed in this washing tank 18 is carried to the next processing step after the processing is completed.

が収縮する。Next, the effect will be described. When the cotton knit fabric 1 is immersed in a caustic soda solution of a certain concentration while the fabric is stretched out, the alkali is adsorbed to the 11!1 lllll fibers, and as a result, it becomes alkali cellulose and becomes cellulose. Intermolecular hydrogen bonds are broken, the crystal structure changes, and the knitting structure contracts.

り有効なシルケット加工が達成できる。This alkaline cellulose is unstable and alkali is liberated by washing with water to regenerate the cellulose. The regenerated cellulose has a crystal structure different from that of the cellulose before treatment, and its gloss dyeability, dimensional stability, etc. are improved. This cellulose before alkali treatment is cellulose■
So, cellulose after alkaline treatment and water washing is cellulose! ■ Say. The cotton fibers are immersed in a caustic soda solution and sufficiently swollen with alkali to remove distortion of the fibers and remove local weak points, followed by stretching to improve the arrangement of cellulose molecules, resulting in alkali treatment. The purpose of mercerization, that is, effective mercerization, can be achieved.

-Na''+H,0 (alkali adduct) = Cell-ONa + H2O (alcolade) It is interpreted that the alkali adduct and the alcolade have an equilibrium relationship, and that this equilibrium is tilted toward the alkali adduct. When it changes to alkaline cellulose, the conventional hydrogen bonds between hydrogen groups between cellulose molecules are broken by Na, and the bonding force between cellulose molecules weakens, causing a difference in ion concentration outside the core of the fiber due to the adsorption of Na ions, which causes penetration. When pressure is generated, the fibers swell and the crystal structure changes, causing untwisting and shrinkage.This alkaline cellulose is unstable, and when washed with water, NaOH is gradually replaced by I (20), forming water cellulose (Ce1-0H). It is dehydrated with boiling water to become hydrated cellulose (Cell-OH)・n) 1.0, which is dried to form the original cellulose
). The cotton fibers regenerated in this way have a crystal structure different from that of conventional cotton fibers, distortions are corrected, local weak points are removed, and the arrangement of cellulose molecules is improved by elongation, giving it a glossy texture and dyeing properties. The dimensional stability etc. are improved and it becomes Cellulose II. Acid neutralization treatment is performed to save washing water and shorten treatment time to convert alkaline cellulose into hydrated cellulose. Cotton fiber products shrink by about 30% when a certain amount of NaOH is adsorbed, so both the fabric and the fabric are kept under tension to prevent shrinkage.

果がある。In this way, in the present invention, when the cotton knit fabric to be treated is treated with alkali, the fabric is tensioned in the width direction, and then during the hot water washing process, the tension is loosened, and a large amount of alkaline agent is applied to the fabric. By allowing the material to remain and then tensioning it again in the width direction during the subsequent acid neutralization treatment, the resulting mercerized fabric, i.e., cotton knit fabric, does not undergo hot water shrinkage and maintains excellent dimensional stability. There is an effect that can be done.
