DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cellulose fiber yarn.
The present invention relates to a method for processing the skin of Tencel yarn (trade name), a processed yarn generated by this processing method, and a knitted fabric woven and knitted using the processed yarn.

[0002]

2. Description of the Related Art Heretofore, there has been no known processing method for subjecting yarns other than Tencel yarn to a surface treatment step as in the present invention. The following processing method has been adopted for Tencel yarn. (1) Processing at the yarn stage (1-1) The raw yarn is knitted into a sock tube, and this fabric is fibrillated by tataki, fir processing, etc. by a processing machine, and then fibrillated by enzyme treatment. Remove fluff,
The dough arranged as a dough is unwound as a thread with a threader and wound around a cheese or cone again for use. The term “fibrillation” as used herein refers to a phenomenon in which the outermost layer of Tencel yarn is split by a physical friction or impact. (1-2) Take the cheese-like raw thread into a lump, temporarily sew it, fir it with a processing machine, etc. to fibrillate, treat it with an enzyme in the lump state, dry it and wind it around a cone. Use it. (2) Processing at the fabric stage (2-1) Dyeing non-fibrillated yarn, knitting and weaving, then using a processing machine to make fibrillated by fir processing and fir processing to make it fluffy and enzymatic treatment by biotechnology How to give a soft texture. (2-2) Furthermore, weaving and weaving the original yarn,
There has been a method of performing fibrillation by fir processing, dyeing and finishing through the steps of enzyme treatment and dyeing treatment.

[0003]

In the above conventional example,
(1) In the processing at the yarn stage, a complicated process of once forming into a tubular knitting shape, fibrillating with a processing machine, performing an enzyme treatment, and returning to a yarn state is employed. Therefore, not only is the processing step lengthened, but also uniformity is impaired due to processing in small quantities, and uniformity between lots is lost even in enzyme treatment by biotechnology, resulting in non-uniform finish.

[0004] In addition, there is also a problem that the production is in a small quantity, the number of processing steps is long, and the cost is high.
Also, (2) processing at the fabric stage is very difficult, and there is a considerable difference in the processing state depending on the quality of the processing machine, and it takes a long time (for example, 5 to 10 hours) to fibrillate. There was a problem that the occurrence rate was 20 to 30%. Furthermore, with regard to woven fabrics, "raw folds" occur, and wrinkles and streaks enter in approximately 2-3 days after weaving,
In the subsequent processing in the subsequent process, there is a problem that "raw broken" state, wrinkles, and streaks remain. The term “raw fold” as used herein refers to a state in which the folded portion does not return to its original state when the woven fabric is folded.

It is an object of the present invention to provide a tencel yarn in which splitting occurs in the outermost layer of the fiber yarn by applying physical friction or impact to the skin of the yarn at the yarn stage, thereby producing a navy hair or volume processing. Soft texture appears as if
It can be fibrillated continuously and in a short time so that it can be knitted and woven in the same way as ordinary cotton or rayon by enzymatic treatment with biotechnology, etc.
It has uniformity as finished yarn, and to provide a yarn that unnecessary fibrillation in the fabric stage staining is also possible
Things . In addition, at the stage of making the fabric, we will be able to dye fabric like ordinary cotton, do not generate raw breaks, wrinkles, streaks, etc., reduce costs, and provide a knitted fabric of Tencel yarn that can be mass-produced It is assumed that.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The skin processing method of the present invention is applied to a tencel yarn.
Since the surface treatment is performed, the added value increases. Hereinafter, an example of fibrillation using Tencel ( trade name of Courtes Ltd., UK) as a cellulosic fiber yarn will be described. (Example 1) Tencel thread 40th was used.

(Wetting Step) The Tencel yarn is wetted using a cheese dyeing machine or the like. Temperature 60 ° C, caustic soda was added in a small amount. (Rubbing process) a. Intersecting angle between the yarn and the yarn 30 degrees b. Twisting the yarn once to make six crossings at the rubbing portion and rubbing.

The sheath layer with a fibrillation rate of 50% at 400 m / min was removed by a bio-treated enzyme. c. See attached Figure 1. In the figure, 1 is a cheese which has been wetted in advance, 2 is a tencel thread, 3 is a rubbing portion, and twisted once, 6 times (A to F)
Indicates the intersection of 4 is a motor, 4 'is a conduction belt, and 5 is a winding part. (Example 2) Tenth thread 40th is used.

(Wetting Step) The cheese was immersed in a thread wet immersion apparatus all day and night. Maintain at 60 ° C with temperature controller. For harmony with productivity (winding speed), a water supply and temperature control system was added and automatic control was performed. (Rubbing process) Twisting the yarn once, passing 9 times at the intersection, resulting in a fibrillation rate of 7
It was 0%.

As a comparative example, when the yarn was twisted once and passed through the intersection 12 times, the fibrillation rate was excessively advanced. (Example 3) Tenth yarn 40th was used, and the wetting process was the same as in Example 1. (Rubbing process) Twist the yarn 5 times and pass twice at the intersection.

The degree of fibrillation was 80% at a winding speed of 270 m / min at 60 Hz. In addition to the above embodiment, steam (temperature of 100 ° C.) can be used at the time of rubbing to make the fibrillation more efficient. In the above embodiment, the twist of the yarn is twisted once, and twisted five times. As shown,
It is adjusted appropriately in consideration of friction between the yarns within a range where the yarns are not entangled.

Further, in the winding section after the fibrillation, a means such as soft-winding at a high speed so as not to apply tension is used.

[0020]

In the present invention, by the wet process and the surface treatment process of the yarns, the surface of Tencel yarn processing hairs out and volumes out of a cellulosic fiber yarn, soft
Since the texture appears and is fibrillated at the yarn stage, splitting is easy, and continuity and uniform processing is possible. Yarn dyeing is possible as with cotton and rayon, and the cost can be reduced. It is not necessary to re-fibrillate such a surface-processed yarn after weaving, and even if the yarn is woven and folded, the sheath itself is removed and the yarn itself has flexibility. And the like, and can provide high value-added products.

In particular, after the fibrillation of the Tencel yarn, an enzyme treatment by biotechnology is performed to remove the fluffy portion, whereby the flexibility is further improved. Further
Yarn can be easily dyed at ordinary dyeing factories as a yarn , and flexibility and volume can be obtained. Knitting and weaving are easy and added value is greatly improved. Knitting and weaving possible as yarn dyed as Tencel yarn
The formation is easy, and the knitting and weaving are also possible, and the marketability can be further improved. Moreover, because you can get a sense of volume,
With soft touch, we can also provide fabrics with fine fluff such as powder skin touch or micro peach skin touch, reducing production costs, expanding production volume, maintaining product uniformity, and making products universal. It has become possible to provide high value-added products that contribute to
