JPH03183597A - Touch moderation of formed end aperture brim of finger stall - Google Patents

Abstract

PURPOSE:To reduce manufacturing labor and time significantly and obtain a product which gives a satisfactory feeling of fitness to the finger tip by fusing thermally fusable yarns which make the formed end part of a body of finger stall in a final stage of processing and fixing the fusable yarns at the formed end part. CONSTITUTION:The body 1 of a completely formed finger stall is thermally processed through water at temperatures of 90 to 100 deg.C when it is subjected to a following soaping and dyeing process. In this case, the finger stall is formed using an elastic yarn 2a in the formed end part 1d and a particular thermally fusable yarn 2b in the enclosure. Therefore, the thermally fusable yarn becomes molten at about 60 deg.C. However, the elastic yarn remains unchanged qualitatively, if it is thermally processed, but the thermally fusable yarns become fused together, Consequently, the touch moderation process of the formed end part is performed in the existing process and the feeling of fitness to the finger is improved due to the elastic yarn.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is applied to the production of a knitted finger cot used for hitting or office use, and the present invention is applied to a knitted finger cot at the knitted end edge of the knitted end of the knitted finger cot. , prevents the knitting yarn from unraveling1
This invention relates to a method for preventing unraveling.

(Prior art) When knitting Nitto's finger cots, knitting yarn is used as shown in Figure 3 (a)! ! There are those in which the fingertips of the previously formed cylindrical body a are sewn with knitting yarn, and those in which a linking part C is formed at the fingertips of the front same cylindrical body a, as shown in the same figure ()). Figure 3 (c) due to the poor fit of the fingertips.
As shown in the figure, a finger cot has been realized in which the knitting starts from the fingertip part d without a seam and continues knitting 1-1 up to the cylindrical part e.

But 2. In this case, at the knitting end edge f of the cylindrical part e,
The knitting threads will touch each other, so to prevent this,
It was necessary to sew the knitting end rim f with the non-touching thread g.

As a result, when using the above-mentioned finger cot, the hanging end [] edge f does not fit well to the fingers, and moreover, considerable time and effort must be spent on the sewing work, resulting in high costs. Become.

Therefore, in order to improve this problem, a new structure for the knitting end for the purpose of preventing contact as shown in Fig. 4 has already been proposed.
A method has been proposed (Japanese Utility Model Publication No. 14611/1982), and a method for preventing touching of the knitted edges of composite gloves (Japanese Patent Publication No. 17938/1981) has already been implemented.

According to the prior art of the person described in I7, as clearly shown in FIG. 4, from the fingertip portion d without knitting 11 to the cylindrical portion e is knitted as shown in FIG. 3(e). 1. When the knitted end edge f of the tubular body e is reached, the knitted end g is knitted by twisting heat-treatable fibers such as woolly nylon into the knitting yarn, and then subjected to a conventional crimp process. After obtaining the product A, the product A is subjected to high frequency treatment "J-B" as shown in FIG. 1 to obtain a finished product A°.

In addition, in the case of the latter conventional technique, which is a technique related to glove knitting, when the glove (not shown) is knitted from the fingertip side until it is near the end edge of the wrist, the subsequent steps are as shown in FIG. It is knitted using stretchable knitting threads such as

Here, the elastic knitting yarn refers to a winding device 2 in which a bobbin yarn j that does not have heat fusibility and thermosetting properties is wound around a core yarn i made of elastic yarn, and then a heat fusible yarn k is wound over the bobbin yarn j. It's something you can ask for.

In this case, as well as the former technique shown in Figure 4,
After the product is obtained by performing the shrinking process, etc., it is further subjected to high-frequency heating treatment to melt and solidify the above-mentioned heat-sealable yarn.
As a result, the heat-sealing threads are fixed to each other to prevent contact.

The above method also overcomes the drawbacks of the old method.
However, the above-mentioned heat-processable fibers and heat-fusible yarns are melted by high-frequency heating, and at this time, the melting point of nylon fiber yarns is 21
Since the temperature is 5° C. to 260° C., the knitting yarn etc. are also heated at a considerably high temperature when the high frequency heating treatment is performed.

However, the cotton yarn used as knitting yarn decomposes at 150℃, and the temperature of 260℃~
Because it has the property of carbonizing at 300°C, products such as finger cots and gloves will suffer from a considerable decline in quality in terms of texture, elongation, etc. due to deterioration of the cotton yarn or spantex.

In addition, as mentioned above, no matter which conventional method is used, the product is subjected to a separate high-frequency heating treatment after the existing processes such as knitting, dyeing, and soaping have been completed, resulting in double labor and effort. It is necessary to carry out treatment,
As a result, the cost of the product inevitably increases.

(Problems to be Solved by the Invention) The content of the present application has been studied in view of the deficiencies of the above-mentioned prior art. In addition to knitting with elastic knitting yarn, which has a core yarn made of elastic yarn and exterior heat-fusible yarn that generates heat-fusible properties at temperatures below the boiling point of water, it also requires the subsequent dyeing process and nooping. By melting and solidifying the above-mentioned heat-fused yarn by heating the filtrate medium in the existing processes such as manufacturing processes, we can fundamentally solve the problem of deterioration of knitting yarns etc. caused by the high temperatures caused by conventional high-frequency heat treatment. In addition to solving the problem, it also achieves the purpose of fixing the heat-fused yarns to each other during the normal manufacturing process, greatly reducing manufacturing labor and time. The purpose of this is to provide a product that can significantly reduce the cost and provides a good fit for the fingertips.

Furthermore, in claim (2), the heat-fused yarn in the stretchable curled yarn described in E is not wound directly around the core yarn made of elastic yarn, but is wound through a lower yarn that does not heat harden at the boiling point of water. By winding the elastic thread, the elasticity of the elastic thread can be fully demonstrated, which improves the fit to the fingertips, and allows only the heat-fused threads to be fused together. The purpose is to exhibit and obtain a satisfactory contact prevention effect.

Furthermore, in the method of claim (1), the core thread and the bobbin thread are made of a specific material, and the heat-fused thread is made of polyvinyl chloride. This makes it possible to more accurately identify distant relatives.

(F-stage for solving the problem) Since the present application is distantly related to the above-mentioned object, in claim (1), the process is performed sequentially from the fingertip to the cylindrical part so that there is no seam at the fingertip. After knitting and reaching the knitting end edge of the cylindrical part, the core yarn made of elastic yarn was covered with a heat-fusible yarn that became heat-fusible at a temperature below the boiling point of water. Multiple courses are knitted using the stretchable knitting yarn, including the final course that forms the knitted end of the finger cot main body. The knitted end edge of the finger sack is characterized in that the heated fused yarns of each course are fused together by heat, thereby fixing the fused yarns to each other at the L knitting end. I'm trying to provide a first-hand method.

In claim (2), the stretchable knitting yarn in claim (1) is combined with a core yarn made of elastic yarn, and a core yarn made of elastic yarn, and a core yarn of water twisted with this without any gaps.
Heating of a bobbin thread made of a thick bobbin thread that does not heat harden at the boiling point, and a thin thread that becomes heat-fusible at a temperature below the boiling point of water twisted to the bobbin thread in the opposite direction. Its content is that it is composed of fused thread.

In claim (3), the stretchable knitting yarn in claim (1) is further characterized in that the core yarn, which is an elastic yarn, is made of one of rubber yarn and polyurethane, and the lower yarn is made of acrylic, nylon, polyester,
The content is that one of the yarns is made of rayon, and the heat-fused yarn is made of polyvinyl chloride.

(Function) When using the method of claim (1), by subjecting the finger cot body that has been knitted to the next soaping process or the dyeing stage, it is possible to apply 1
The heating treatment is carried out through water at a temperature of 00°C. At this time, in the present invention, when knitting the above, the knitting ends are made of elastic yarn,
Since it is knitted with a unique heat-fusible yarn on the exterior, the heat-fusible yarn becomes molten at a temperature of about 60°C.

However, at this time, the properties of the elastic yarns do not change due to the heating treatment, and the heating and fusion yarns become fused to each other, and the ends of the knitting are prevented from touching as described above. In addition, the elastic thread provides a better fit for the fingers compared to conventional high-frequency heating devices.

If the lower thread is placed outside the elastic thread and the lower thread is further covered with a heat-fusible thread as claimed in claim (2), the heat-fusible thread protects the elastic thread. It does not interfere with expansion and contraction, and since the bobbin thread does not heat harden at the boiling point of water and is made of large-count thread material, it does not harden even during the dyeing and soaping processes. ,
This completely eliminates problems such as the expansion and contraction of elastic yarns caused by heat-fused yarns.

In claim (3), one elastic thread is rubber thread or polyurethane,
By using one of acrylic, nylon, polyester, or rayon for the bobbin thread and polyvinyl chloride for the heat-sealing thread, the effects described in claims (1) and (2) can be achieved. It is definitely possible.

(Example) The present invention will be described in detail below with reference to FIGS. 1 and 2. First, as in the conventional example, using knitting yarn such as cotton yarn
As shown in Fig. 1, if the fingertip portion 1a is knitted sequentially from the fingertip portion 1a to the cylindrical portion 1b so that there is no seam, and the knitting is made to the side of the knitting end edge lc of the cylindrical portion 1b, , second
The knitted end of the finger cot main body l is formed by an elastic knitting yarn 2 made of a core yarn 2a made of an elastic yarn as shown in the figure and covered with a heat-fused yarn 2b that melts at a temperature below the boiling point of water. A required number of courses including the final course 1d are organized.

Here, the elastic knitting yarn 2 shown in FIG. 2(a) is directly heat-fused to a core yarn 2a formed of an elastic yarn made of comb type, polyurethane, etc. Thread 2
b, and the fused thread 2b has a 60° angle.
It is desirable to use polyvinyl chloride that melts at temperatures below about C.

On the other hand, in the stretchable knitting yarn 2 shown in FIG. 2(b), first, the lower yarn 2C of the large-count yarn, which does not thermoset at the boiling point of water, is inserted without any gaps between the core yarn 2a made of the above-mentioned tar yarn. The above-mentioned heat-fusible thread 2b is twisted to this bobbin thread 2C in the opposite direction, and the heat-fusible thread 2b has a finer count than the bobbin thread 2C. As the lower thread 2C, acrylic, nylon, polyester, rayon, etc. can be used.

In this way, once the knitted finger cot main body l is obtained, it is subjected to a heating treatment using water as a medium in the tank body 3 of the existing processes such as the nooping process and the dyeing process according to a conventional method. However, for example, in the case of dyeing process, 90~
The treatment will be performed at 100° C. for about 2 hours.

Therefore, in the above-mentioned existing process, the above-mentioned heat-fused yarn 2b
However, the heat-sealing yarns 2b exhibit heat-sealing properties below the boiling point of water, and as a result, the heat-sealing threads 2b in the plurality of courses at the knitted end 1d of the finger cot main body 1 are fused to each other. As a result, the knitting end 1d becomes a touching stop portion ld' as shown in FIG.

At this time, compared to the case of the elastic knitting yarn 2 shown in FIG. 2(a), the lower yarn 2c is inserted between the core yarn 2a and the heat-fused yarn 2b as shown in FIG. 2(b). There is no need to worry about the heat-fused yarn 2b interfering with the expansion and contraction of the core yarn 2a.
A desirable result is obtained, and since the bobbin thread 2C is not thermally hardened at the boiling point of water, the elasticity of the core thread 2a and the overall soft feel are maintained.

(Effect of the invention) Since the present application is implemented as described above,
According to claim (1), the touch prevention process can be completed within the existing process of manufacturing this type of finger cot, and a separate process of performing high-frequency heating treatment again after the completion of the existing process as in the past, can be performed. There is no need to go out of your way to do this, and it is possible to significantly improve productivity and provide inexpensive products.

Moreover, since a heating treatment using water as a medium is required instead of high-temperature treatment such as high-frequency heating treatment, the knitting yarn, elastic yarn core yarn, F yarn, etc. may be decomposed by the treatment. Furthermore, it is possible not only to obtain a complete contact-tight state without causing problems such as carbonization, but also to maintain good properties between fits in terms of texture and elongation due to the core yarn.

Seihoko 0 (')' + upper fin Al±, lower thread The adoption of elastic knitting yarn using heat-fused yarn, the above claim (1)
When implementing methods related to this, it will greatly contribute to ensuring better quality.

In claim (3), claims (1) and (2) are explained by specifying the materials of the core yarn, bobbin yarn, and heat-fusible yarn for the stretchable knitting yarn. Regarding the various effects,
This will ensure its stability.
