Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is worn for the purpose of safety, prevention of dirt, heat retention, etc., at construction sites, civil engineering sites, and in various works such as machine work, automobile repair, automobile driving, and garden work. The present invention relates to working gloves made of fibers.

2. Description of the Related Art A conventional fiber working glove is an arbitrary short fiber for knitting obtained by spinning a card-raising roving (hereinafter referred to as "wool-shino") in a wool spinning process with a ring spinning machine or an air spinning machine. The metric type 4-12 count yarn consisting of is used as a single yarn or two of the above yarns are used as a metric type 4-7 count yarn and knitted with a 3-10 gauge sinker type glove knitting machine. It was common. However, in this case, it is necessary to reduce the yarn breakage in the spinning process and the yarn breakage in the winder process for rewinding from the spinning bobbin to the corn or the next knitting process. K (however, the twisting coefficient K is expressed by the formula K = T / √, where N _m is the yarn count and T is the number of twists / m).
(Defined by N _m ) has increased the strength of the yarn by adding a large twist of 70 or more, resulting in high spinning cost and poor bulkiness and flexibility of the obtained yarn.

In order to solve these problems, a woolen shinoba is manufactured to have a thickness half that required for a knitting yarn, and two thin woolen shinoko are aligned and placed on a rotatable disk prepared at the entrance of a knitting machine. A method has been developed in which the disc is placed in the shin state, and the disc is rotated to twist and twist the wool and feed it to the knitting machine to facilitate the unwinding of the wool and to reduce the tension load. However, even in this case, there is a problem that the strength of the yarn required for knitting is insufficient and the yarn breaks frequently, resulting in a significant decrease in productivity.

[0004]

DISCLOSURE OF THE INVENTION The present invention increases the bulkiness, flexibility and heat retention of work gloves knitted using the above-mentioned knitted fibers to improve the feel and fit and to wear them. The workability at the time is improved, the productivity is improved, and the work gloves can be inexpensively provided.

[0005]

That is, a work glove according to the present invention is configured such that a roving yarn consisting of an arbitrary short fiber for knitting is used as a core fiber, and a filament yarn of synthetic fiber is used as a binding yarn to form a spiral shape on the core fiber. It is a knitted glove knitted using wrapping yarn formed by winding the wrapping yarn, wherein the fineness of the binding yarn is 15 to 200 denier, and the weight ratio of the binding yarn to the wrapping yarn is 1 to 10
%, And when the metric number of the wrapping yarn is N _m and the number of wrapping is T times / m, the wrapping coefficient K defined by the formula K = T / √N _m is 40 to 70, and the cutting yarn of the wrapping yarn is It is characterized by a strength of 350 g or more.

The working glove of the present invention uses a wrapping yarn composed of a core fiber and a binding yarn as a knitting yarn. The core fiber accounts for 90 to 99% of the weight of the knitting yarn, that is, the wrapping yarn. , Is the main constituent fiber that controls the bulkiness, flexibility and texture of the knitting yarn. The type, fiber length, and fineness of the knitting fiber used as the core fiber are not particularly limited, and the color is arbitrary, but a chemical fiber or a synthetic fiber that can be used while making the best use of the whiteness of the raw material is preferable. Further, the fineness is preferably 1 to 5 denier from the viewpoint of feeling when worn. Further, the fiber length is preferably 38 to 76 mm from the viewpoint of good workability with a woolen card. In addition, as the core fiber, a roving yarn with almost no twist is used, but this roving yarn has few restrictions on the fiber raw material and has high productivity, and thus the woolen yarn has been conventionally used for gloves. Shino is preferable, and the cutting strength of the woolen Shino is preferably 40 to 80 g in terms of handling.

The above-mentioned binding yarn spirally wound around the core fiber imparts strength to the knitting yarn,
Thin, high-strength synthetic fiber filament yarn is preferred,
For example, multifilament yarns of polyester, nylon 6, nylon 66, etc., which have a strength of 4 g / d or more and are widely used in the market are exemplified. In the present invention, the total fineness is 15 to 200 denier, preferably 20 to 50 denier. Multifilament yarns are used.

The knitting yarn used in the present invention is a wrapping yarn obtained by spirally winding the above binding yarn around a core fiber. The strength of the wrapping yarn increases as the number of windings (twisting number) of the binding yarn, in other words, the wrapping coefficient K increases, but on the other hand, the core fiber is covered with the binding yarn and its bulkiness increases. Flexibility is impaired. Therefore, in the present invention, the weight ratio of the binding yarn to the wrapping yarn is 1 to 10
%, Preferably 1 to 5%. The wrapping coefficient K is set to 40 to 70, preferably 40 to 60.

For the above wrapping yarn, a wrapping spinning machine is used, the above-mentioned woolen fiber (core fiber) is supplied to the drafting device, and the draft is added and introduced into the upper end of the hollow spindle below the front roller, and At the upper end of the hollow spindle, a binding thread drawn from a binding thread bobbin fitted on the outside is introduced.
It is advantageous that false twisting is applied to the core fiber by a false twisting mechanism at the lower part of the hollow spindle, and the binding yarn is wound around the core fiber by untwisting that occurs below the core fiber and wound on a cheese bobbin.

[0010]

The working glove of the present invention is a knitted glove that is knitted using a wrapping yarn having a roving yarn as a core fiber and a synthetic filament yarn as a binding yarn, and the weight of the binding yarn in the wrapping yarn. Ratio is 1
Since it is 10%, most of the knitting yarn can be covered with wool, which enables low-cost production, and the bulkiness, flexibility, and heat retention of the core fiber are directly expressed in work gloves. Improves the feel and fit of work gloves and workability when worn. Moreover, since the knitting yarn is a wrapping yarn in which the above-mentioned core fiber is reinforced with a binding yarn (synthetic fiber filament yarn), the strength as a knitting yarn is sufficient and knitting of gloves can be performed easily. It is possible and productivity is improved.

However, the fineness of the binding yarn is 1
If it is less than 5 denier, the reinforcing effect of the knitting yarn is not sufficient and knitting becomes difficult. On the other hand, if it exceeds 200 denier, the knitting yarn strength is increased more than necessary and the manufacturing cost is increased. When the weight ratio of the binding yarn to the wrapping yarn is less than 1%, the reinforcing effect required for the knitting yarn tends to be insufficient, and when it exceeds 10%, not only the production cost increases but also the core The fiber coating becomes excessive, bulkiness,
Flexibility and heat retention are reduced. When the wrapping coefficient K is less than 40, the coating of the core fiber with the binding yarn is not sufficient, so that the guide and knitting needles during knitting cause dissociation between the core fiber and the binding yarn, and Since it is an almost untwisted fiber bundle, the cutting thread strength of the wrapping thread decreases, and when this cutting thread strength is less than 350 g, the number of thread breakage increases and the productivity decreases, and conversely the wrapping coefficient K When it exceeds 70, the core fiber is covered with the binding yarn, and the bulkiness, flexibility and heat retaining property are lost.
