Description

  The present disclosure relates to a work hood.

  For work that requires cleanliness, such as semiconductor manufacturing, pharmaceutical manufacturing, and food manufacturing, a work hood that completely covers the head is used to prevent foreign substances such as hair from entering the product. (For example, refer to Patent Document 1). The work hood of Patent Document 1 works by fixing two cloths hanging from both sides of the face near the chin using fasteners such as snap buttons integrated with hook-and-loop fasteners and tape fabric. The face was exposed while the hood was fitted to the face.

  Since fasteners such as hook-and-loop fasteners have irregularities, dust in the washing tub gets caught in the irregularities during washing. If the work hood is used in this state, the fastening of the fastener becomes sweet, and the fastener may come off during the work. Further, if the dust adhering to the uneven portion of the fastener is peeled off during the work, it will lead to foreign matter mixing.

It is a schematic diagram which shows an example of a knit structure. It is a mimetic diagram showing the state (when wearing spectacles) where the work hood concerning the embodiment of this indication was used for the head.

  Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In addition, this indication is not limited to embodiment shown below. These embodiments are merely examples, and the present disclosure can be implemented in various modifications and improvements based on the knowledge of those skilled in the art. In the present specification and drawings, the same reference numerals denote the same components.

  FIG.1 and FIG.2 shows an example of a structure of the working hood which concerns on embodiment. The working hood 1 according to the embodiment has an opening 11 that exposes at least a part of the face while covering the wearer's head. At least a portion of the face includes the nose and eyes. The opening 11 may expose the mouth.

  The work hood 1 is entirely formed of a knit material. Thereby, the work hood 1 according to the embodiment uses a knit material having elasticity in a specific direction, so that the work hood 1 is prevented from being excessively deformed and the work hood is placed on the wearer's head. Can be fitted.

The knitted material is, for example, a fabric having a knitted structure of weft knitting in which the horizontal direction _DH of the ground is the longitudinal direction as shown in FIG. Such a knit structure has good stretchability in the lateral direction _DH . The weft knitting structure is not particularly limited, and for example, a conventionally known structure such as rib knitting, rubber knitting, pearl knitting, etc. can be adopted in addition to the flat knitting shown in FIG.

  The fibers constituting the knitted material preferably contain hydrophilic fibers so as to absorb moisture such as sweat. The hydrophilic fiber is, for example, cotton, rayon, or a highly hydrophilic synthetic fiber. The highly hydrophilic synthetic fiber is, for example, Body Oasis (registered trademark) which is a polyester material containing a hydrophilic group. Body Oasis (registered trademark) has high hydrophilicity and does not swell, and therefore can absorb sweat and moisture and emit quickly. Moreover, it is preferable that the fiber which comprises a knit material contains fiber with high heat conductivity, such as an eval, so that the heat | fever of the skin surface may spread | diffuse.

  The work hood 1 includes an annular belt cloth 12, an edge cloth 13, a crown pressing cloth 14, and a hood cloth part 15.

The edge cloth 13 is formed of a knit material that is disposed on the periphery of the opening 11 and that expands and contracts in the circumferential direction 32 of the opening 11. For example, the lateral direction _DH of the knit structure is arranged along the circumferential direction 32 of the opening 11. Thereby, the work hood 1 according to the embodiment can expose the face while fitting the work hood 1 to the face without using a fastener such as a hook-and-loop fastener.

  The edge cloth 13 is preferably formed of an edge cloth upper part 131 and an edge cloth lower part 132. The edging cloth upper part 131 covers the wearer's forehead and expands and contracts in the circumferential direction 32 a of the opening 11. The border cloth lower part 132 covers at least a part of the jaw part of the wearer and expands and contracts in the circumferential direction 32 b of the opening part 11. The rim cloth upper portion 131 and the rim cloth lower portion 132 are joined in the vicinity of the wearer's temple. An angle θ on the side of the opening 11 formed by the edging cloth upper part 131 and the edging cloth lower part 132 at the joint is approximately 90 °, and preferably about 70 to 90 °. Thus, by arranging the edging cloth upper part 131 and the edging cloth lower part 132, the edging cloth 13 is prevented from becoming circular, ensuring a wide field of view of the wearer, and using a fastener such as a hook-and-loop fastener. It is possible to fit the wearer's face exposed to the opening 11 without any problems.

  Since the edging cloth 13 greatly expands and contracts every time it is attached and detached, it is preferable that a plurality of knit materials are stacked so that the stretchability of the knit material is maintained. In this case, it is preferable that the surface containing a large amount of hydrophilic fibers is superposed so that the sweat of the face is efficiently absorbed.

The annular belt fabric 12 is disposed so as to cover the entire upper part of the head, and can expand and contract in the circumferential direction 31 of the upper part of the head. The upper part of the head includes the forehead, the temporal region, and the occipital region. The annular belt fabric 12 can be expanded and contracted in the circumferential direction 31 at the top of the head. For example, the lateral direction _DH of the knit structure is arranged in the circumferential direction 31 at the top of the head. Thereby, the work hood 1 can be fitted to the wearer's head. When the work hood 1 is attached, an appropriate fit is maintained, and no discomfort is given even when used for a long time. The width of the annular belt cloth 12 may be appropriately determined depending on the size of the work hood 1, but may be about 2 to 8 cm. The annular belt fabric 12 is preferably joined at the back of the head.

  In the working hood 1 according to the embodiment, the bordering cloth 13 expands and contracts in the circumferential direction 32 of the opening portion 11 and the annular belt cloth 12 expands and contracts in the circumferential direction 31 of the upper part of the head. 1 can be fitted to the face and head. For this reason, since it is not necessary to fit a hood to a face or a head using fasteners, such as a hook-and-loop fastener, anyone can wear the work hood 1 easily.

  The head top pressing cloth 14 covers the top of the wearer's head, and can be expanded and contracted with respect to the coronal surface, that is, the temporal direction 33. The direction of expansion and contraction of the top portion pressing cloth 14 is limited to the direction 33 of the temporal region, and the annular belt cloth 12 can be held on the top of the head by not expanding and contracting in the direction of the frontal and occipital regions. And the fit feeling with respect to a wearer's top part increases because the top part presser cloth 14 expands and contracts in the temporal direction 33.

The hood cloth portion 15 is disposed adjacent to the annular belt cloth 12 and the edge cloth 13 and is formed of a knit material that expands and contracts in the circumferential direction 34. For example, the lateral direction _DH of the knit structure is arranged in the circumferential direction 34. It is preferable that rubber that expands and contracts in the circumferential direction 34 is disposed at the position of the back of the hood cloth portion 15. Thereby, it is possible to enhance the fit of the wearer's head.

  The working hood 1 according to the embodiment may include a collar portion 22. The collar portion 22 has an arc shape disposed between the annular belt cloth 12 and the edge cloth upper portion 131 and is shorter than the edge cloth 13. Providing the collar portion 22 also has an effect of protecting the wearer's eyes from strong light or dust. Further, by bringing the curvature of the collar portion 22 close to the curvature of the wearer's forehead, there is an effect of fixing the forehead and preventing the hood from moving.

  It is preferable that the working hood 1 according to the embodiment includes a mask hanging portion 23. By providing the masking portion 23, the wearer can easily put on the mask. The mask hanging portion 23 is disposed on the hood cloth portion 15 and locks the mask hanging string. At this time, examples of the parts for masking include buttons, protrusions, metal fittings, and the like.

  The working hood 1 according to the embodiment preferably includes an auxiliary cloth portion 21. FIG. 4 shows a state in which the wearer wears the work hood 1. The auxiliary cloth portion 21 is disposed at a joint portion between the rim cloth upper portion 131 and the rim cloth lower portion 132, one end is sewn together at the joint portion 21 a of the rim cloth upper portion 131, and the other end is joined at the joint portion 21 b of the rim cloth lower portion 132. By being sewn and fixed, the edge cloth upper portion 131 and the edge cloth lower portion 132 can be brought closer to the opening 11 side. Further, in order to enhance the fit of the auxiliary cloth portion 21, the joint portion 21c and the joint portion 21d may be sewn together. There is an insertion portion 21e between the coupling portion 21c and the coupling portion 21d, and the temple of the glasses 4 can be inserted therethrough. By inserting the temple of the glasses 4 through the insertion portion 21e, the wearer can wear the glasses even if the auxiliary cloth portion 21 exists.

  The cloth used for working hoods in the related art is formed of TC (TC: Tetoron and Cotton) (Tetoron is a registered trademark) made by blending Tetron (registered trademark) and cotton (cotton). Since the TC fabric has a dense structure that does not allow hair to pass through, TC fabric has poor air permeability, tends to accumulate heat, and may cause stress on the wearer. On the other hand, since the work hood 1 according to the embodiment is formed of a knit material, the work hood 1 is excellent in breathability, and the heat of the head in the hood can be maintained in a state close to room temperature, thereby reducing the stress on the wearer. it can.

  In addition, the work hood 1 according to the embodiment is strong in strength because it supports the fit with the entire fabric. In addition, since the knit material itself expands and contracts, it is possible to sew a slip-on type that can provide a fit with only the knit material without tightening due to other forces. Further, since the knit structure has good durability in washing, the stretchability is not deteriorated by several washings, and a good fit can be imparted to the work hood 1 for a long period of time.

  When the size of the work hood is M, L, or LL, since the TC fabric is not stretchable, a wearer who has a head with an intermediate size between M and L, etc. An L-size work hood larger than the part is used. For this reason, a gap is generated between the work hood and the head, which may cause contamination. On the other hand, in the work hood 1 according to the embodiment, a person between the head size M and L can wear the M size without any gap because the M size fabric is stretched.

  The work hood 1 according to the embodiment is configured only of a knit fabric without using a hook-and-loop fastener, so that no dust pool is attached due to cleaning or the like. For this reason, the dust attached by cleaning during the work is not mixed as a foreign object during the work.

  The work hood of the present disclosure can be applied to, for example, a work hood at the time of manufacturing a semiconductor, food, medicine, or the like.
