Abstract

covering sliver yarn such as human hair, camel hair, wool or grey wool around the core yarn such as nylon, viscose rayon, polyester filament or cotton which is provided with the tension of 0-50 g/d by the tension-control means in a way that the covering rate of covering sliver yarn against core yarn be 92-100 %; at the site of nipping point of the front roller. The occurrence of slubs is prevented by cutting and stopping feed of the core yarn by means of a cutter placed on top of the front roller when a sensor detects the cuts of the covering sliver yarn. The core yarn made by the method is light and has high- elasticity.

TECHNICAL FIELD The present invention relates to a screen having a high elasticity and a method of manufacturing the same, by coating a screen with a simulated coating on a screen and a method for manufacturing the same, and more specifically, a screen such as nylon, polyester and rayon.

Until now, there are several techniques for the examination of general companies, but the "preparation method of the examination" of Korean Patent Publication No. 84-1634, which is a prior art of the present application, mainly deals with polysaccharides for dress shirts, which cover cotton with synthetic fibers. That is, the manufacturing method itself is different, there is a problem that the screening obtained from the water is also absolutely inferior in the overall characteristics, that is, the strength and elasticity recovery of the yarn.

The general theory of simulated spinning is that the number of cross-section fibers of the yarn that can release the yarn in the spinning process requires at least 30 ol of fiber. Since 30 ~ 100% of screenings are used to produce screenings depending on the item, the number of fiber components must be 50 or more to ensure smooth release, and it is common to release more than 30% of human hairs. Releases above 10 ^NM were not possible (see Table 1).

TABLE 1

The present invention was developed as a result of intensive research to solve the above problems, by improving the spinning conditions by coating the simulation of nylon, polyester, rayon and cotton, etc., is not affected by the number of constituents of coarse raw material It can produce three times up to 5 ^NM of common type than normal spinning, and improves spinning property, and reduces spinning loss by about 50% compared to before use. It improves productivity by maximizing the weaving efficiency and using the high-speed spinning loom.

In addition, the simulation coverage of the screening has the advantage of maintaining 92 to 100%, and the fabric produced by the screening has no resin, or it can adjust the texture by reducing the density and changing the denier of the screening. In addition, it provides the benefits of having a natural texture that is soft and elastic.

In addition, the screening of the present invention can use a high-speed repier loom, which has the advantage that the surface of the wick fabric becomes smooth and there is no straight end.

That is, the present invention provides a method for producing a screening by coating the surface of the rollers in the same area as the screening of the synthetic fiber filament yarn put into the upper and lower front roller gripping point to achieve the above object. In order to cover the irradiation of the mother-of-pearl at the rate of 92-100% to the screening applied to the tension of 0-50g / d, the cutting machine in the upper front roller cuts the screening by pre-cutting the screening by the detection of the sensor during the cutting. It is a method of manufacturing screening to stop the supply and to prevent the occurrence of slip, and maintain high strength and high elasticity. Also, the screening of nylon, polyester, rayon, cotton, etc. is covered with natural wool and elastic recovery. Excellent and low resin concentration.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. The present invention is in no way limited by the following examples.

Figure 1 illustrates a system diagram for the production of the examination of the present invention, the examination (2) is subjected to a constant tension by the tension adjusting means (4) via the examination cutter (6) and the examination guide (14) The examination put into the center of the grip point of the front roller 8 of the pro rollers 8 'and 8 "is bound at the center of the draft part, ie, the irradiation (mother) 12 proceeded to the grip point of the roller 8. The screening (2), which has been subjected to flamming, is covered by the irradiation (12) to produce a screen (Y) of high strength and high elasticity as shown in Figs. 2A and 2B.

When the irradiation 12 coated on the screening 2 in the manufacturing process is trimmed, the detecting means 10 installed at the lower part of the front roller 8 immediately detects it and operates in association with the sensing means 10. The cutter 6 thus installed is operated to cut the screening 2 supplied to the pro-roller 8 side to stop supplying the screening 2.

The use of such a means is that the problem caused by the fact that only the auditor 2 continues to be supplied even when trimming occurs, that is, the loss of the auditor 2 and the auditor 2 to the upper and lower front rollers 8 'and 8 ". This is to solve the occurrence of a slub caused by the change of the pressure of the side rollers due to the winding, and to facilitate the ease of jointing of other yarns.

The operation from the trimming detection to the examination cutting is performed within 1 second, and the indicator lights or a sound generating ring sounds so that workers can easily know when the detection means 10 is detected.

In addition, the tension adjusting means 4 is made of a spring having an elastic force, it is possible to adjust the tension up to 0 ~ 50g / d depending on the kind and denier of the screening (2).

EXAMPLE

The screening (Y) is applied by coating irradiation (12) of human hair, camel hair, wool, gray wool, etc. on the screening (2) of nylon filament, polyester filament, rayon filament, cotton, etc., tension-controlled in the range of 0-50 g / d. Got it. At this time, the coverage of the survey (2) for the examination (2) was 99% or more when the content of the three feedstocks (2) was less than 7%, 94-95% for 7-10%, and 92% for 15-18%. It could be confirmed. Coverage rate is 2 ~ 3% of the above-mentioned value depending on the denier of the fiber, and also can be adjusted by the tension adjustment of the screening, and also the elasticity of the screening can be changed.

The comparison result of the examination (Y) of this invention obtained in this way, and a general company is as follows.

TABLE 2

Spinning test

* Test method: Conducted in accordance with K.S.K.

TABLE 3

Spinning test

Test method: Note to K.S.K.

In the case of Table 2, it can be seen that the screening of the present invention is significantly superior in terms of physical properties when compared to general history.

In the case of Table 3, the average number of cross-sections of NM17 yarns was 26, using 80 ^D / 1 filament at 100% of the release, and the number of cross-sections of 42 yarns was not used.

In other words, when the screening is used as in the present invention, it was confirmed that the minimum number of fibers can be released as 26 (the high elastic triple count production).

TABLE 4

Test of fabric

* Test method: K.S.K 0541 (test for stretch inertia rate of fabric)

Table 4 compares the characteristics of the fabrics served using the screening of the present invention and the fabrics fabricated using the general yarn, and solves the problem of using the formalin resin with the screening of the present invention. In general, resins containing formalin are used to improve the function, form stability, and fusibilities of textile products. According to the present invention, it can be seen from Table 4 that quality improvement, functional improvement, form stability, and fusibilization of textile products are provided without using a resin, and that consumers can obtain the desired quality, function, and feel. Can work

In addition, it completely eliminates the difference in texture between processing parts and stabilizes the crimp ratio. The formalin resin content can be lowered to 300 ppm or less compared to conventional fabrics, and the odor and irritation generated during work are also removed. Could know.
