BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mercerizing method for a wick, which is characterized by subjecting the wick to new mercerizing.

[0002]

2. Description of the Related Art The conventional method of mercerizing cotton cloth is to treat the cotton cloth with a concentrated solution of caustic soda under tension to give it a silky luster and to improve tensile strength and hygroscopic material adsorption. Is well known. About mercerizing 1 Principle of mercerizing mercerizing is a phenomenon in which cotton fibers swell with a thick alkali and change from a flat section to a circular section. When the cross section becomes round, the luster of the fiber becomes similar to that of silk. The name of mercer comes from silk. As alkali, caustic soda or liquid ammonia is used. Caustic potash is expensive and is not used. Change of state of cotton fiber due to NaOH Change of state of NaOH concentration 0… 6% No change 6… 8 Untwisting is completed in 1 second 9 Unfastening is started sooner and later is slowly untwisted 12 Rapidly twisting in 5 seconds Rewinding 16 Swelling after retorting kinks 18 Swelling after untwisting 27 ... 36 Swelling before retorting kinks 2 Method of mercerizing Cotton yarn or cotton cloth is dipped in concentrated alkali and washed with water with tension. The results of mercerizing vary depending on the concentration and penetration of alkali and the tension on the fiber. Conventionally, it was said that a temperature of 10 ° C. or lower was good, but now it is no longer sticking to the temperature. 3 Sirquette processing equipment Skein yarn mercerizing machine-Automatic skein yarn mercerizing machine Warp yarn mercerizing machine Winding mercerizing machine (batch type mercerizing machine) Dry mercerizing machine Chainless mercerizing machine (bend bar type and multi-cylinder type) Clip chain type mercerizing machine Round Knitted knitting machine 4) Effect of mercerizing 1) Improvement of gloss 2) Change in shrinkage and tensile strength 3) Increase in dyeing rate 4) Change in moisture absorption (no tension) and water absorption Unprocessed 6.1% Processed with 8% NaOH 7.7 Processed with 16% NaOH 10.7 Processed with 24% NaOH 11.3 Processed with 40% NaOH 12.15) Improved chemical reactivity (in resin processing and various other processes) Improve the processing effect) 5 Test method for mercerized cotton 1) For the amount of moisture absorption, the amount of dyeing or the amount of adsorption of variome Constant 2) Measurement of coloration degree by the iodo-potassium iodide or iodine-zinc chloride solution

However, this conventional mercerizing method has a drawback that the mercerizing process cannot be carried out at a low cost because the process is long.

Since the wick is not processed by mercerizing because it goes into the obi, silk and wool obi have come out recently, and the demands on the feel of the wick have become strict. But,
Treatment agents such as thermosetting resin processing agents affect the outer strip.
Do not perform any of these processes because
won. Therefore, improvement of the texture and light that do not affect the belt
It is intended to provide a finishing processing method.

[0005]

The present invention has been made to solve the above problems, and is configured as follows. That is, the method for mercerizing the wick of the ribbon of the present invention is to raise the ribbon, paste it, then immerse the ribbon in an emulsion type processing agent, dry it with a dryer, and then heat it with a calendar. a well of a characterized by mercerization pressurized, From a short step
In addition to making mercerizing possible, silk and sheep
Where you can handle the strict demands on the feel of the hair band
Has technical significance. Next, the present invention will be described in detail with reference to examples.

EXAMPLE First, the band core is raised to cause fuzzing. At this time, raising is favorable once, which is a condition. Next, paste processing is performed according to the following procedure. Glue processing 1 time-Polyzol S-5 (vinyl acetate resin) 2l / 100l- (stable stability) (large adhesive strength) -Softex AK-2D (softening agent) 1 / 2l / 100l-Petrox P200 3l / 100l- Water-repellent resin processing agent (preventing strong deterioration) After the band core has been subjected to paste processing as described above, it is dried in a dryer. Then, the band core is further calendered and finished. Calender pressure is 300K
If it is less than g, it is not suitable for making the texture of silk, and if the pressure is too high, the woven fabric becomes flat and hard and becomes like paper. Therefore, the pressure of the calender is 600 kg strength, and it is characterized by crushing the woven fabric, causing the woven fabric to be appropriately bent, and fluffing the surface. In the above example, (paste processing (polysol S-5 and soft
Kusu AK-2D) and emulsion type processing agent (Petrok
This is a two-stage process of
Particularly important technical points in the invention are as follows. i) Raising once fluffing is made by raising, but it is
Unevenness on the surface of the woven fabric due to fluff
To improve the smoothness and gloss . ii) Paste-processed vegetable starch and vinyl acetate-based heat-curable resin (for example,
Sum high content KK made Porizo Lumpur S-5) and softener (e.g. flowers
Improvement in texture by Softex AK-2D made by King KK ,
Stabilization of the fabric shape is achieved, but both are non-formalin
Since it is a processing agent, it can be used for fiber and dyeing of silk and wool belts.
There is no effect. iii) Processing with emulsion type processing agent and calendar
Finishing synthetic polymer wax (straight chain with average carbon number of 20-35)
With a molecular weight of about 300 to 500 containing hydrocarbons as the main component
Basically, Japanese hydrocarbons. Nonionic polyethylene
Processing agents emulsified with surface-active substances (eg
Meisei Chemical Petrox 200) is applied to the core and then dried
Light and dry by heating with a calendar.
Sawa finish and silky texture can be obtained. The emulsion machining
The agent consists of wax and non-ionic activator
So, there is no effect on the obi .

[0007]

As described above, the paste processing of the present invention is mainly composed of paraffinic components and is made into an emulsion by using a nonionic activator of polyethylene.
Since it is an oily, drainable, nonionic emulsion, it can be used for a long time and can be stored. Further, although the strength is lowered in general resin processing, the wax functions to prevent the strength deterioration due to the above-mentioned resin processing. Therefore, the finished band core has an elegant luster, and is supple and silky. As a matter of course, the dyeing has good dust absorption of the dye, and has the property that the adsorptivity is increased by 40% as compared with the conventional product. Moreover, it has an appropriate wrinkle resistance to the supple texture and is most suitable for the band core. In addition, silk and sheep along with the also in combination with excellent economics inexpensive easy to be a short process
It can handle the strict feeling requirements for hair band cores.
