PROBLEM TO BE SOLVED: To provide a rope with markers and markers in which when ropes are stretched or baskets and nets are spread in planting of field crop or in culture of laver and shellfish such as oyster, etc., when an athletic field or a vacant lot is zoned to install a simple parking area, when fences and stakes are installed in construction, when lines are drawn on a ground or when trees are planted, an operation target part is recognized by markers and a target operation is carried out in good operation efficiency.SOLUTION: The rope with markers includes markers M, at every desired interval L, which are provided with marker bodies 1 openable and closable through hinges 2 by a synthetic resin and marker lid members 3 and are composed of engagement elements 4 mounted on the marker bodies or the marker lid members, detachable engagement recesses 5, rope insertion half holes 7A and 7B obtained by halving rope insertion holes 7 into which a rope 6 is inserted in the marker bodies and the marker lid members and detachable latching projections 9 that bend the rope in a curved state on inner peripheral walls 8 and 8' of the rope insertion holes and displaced to the outer periphery of the rope.

PROBLEM TO BE SOLVED: To provide a method for bleaching, by which cellulose fiber products after the bleaching hardly show yellowing even if they are exposed with heat, etc.SOLUTION: This method for bleaching is performed by using an Obermaier dyeing machine. The Obermaier dyeing machine is equipped with a tube having an ozonic water-flowing hole in the inside. By filling the cellulose fiber products such as cotton around the tube, a cellulose fiber product layer is formed. Then, the ozonic water is allowed to pass many times toward the outer periphery of the cellulose fiber product layer from the flowing hole to bleach the cellulose fiber products. Here, the concentration of the ozone in the ozonic water is adjusted at 1-9 mg/L and its temperature at 0-40°C. Also, the time for reaching of the ozonic water to the cellulose product layer from the flowing hole is set to be within 5 min. Further, the bleaching time of the cellulose fiber products by the ozonic water is set to be within 60 min. Thereby, the cellose fiber products hardly showing the yellowing are obtained.

PROBLEM TO BE SOLVED: To provide a drilling implement for fix-planting seedlings such as strawberry, drivable using an existing electric tool for fitting tool parts such as a drill and a driver exchangeably with attachments, capable of drilling holes for fix-planting seedlings in ridges automatically and in high operating efficiency, thus reducing labor and time, with the holes in a soft condition leading to good seedling rooting after fix-planting with suitable seedlings growth. SOLUTION: The drilling implement comprises: a passive rotary shaft body 3 with its tip provided with a sharp part 4, set up rotatably through receiving the rotating force from a drive-side rotating shaft 1 on an attachment 2 set on a drive-side rotating shaft 1 set up rotatably by a motor M, with the basal end part 3a of a drilling unit U detachably fitted on the attachment of an existing electric tool A for fitting several fitting tool parts such as a drill and a driver exchangeably with attachments 2; a spiral body 5 wound in several pitches on the outer circumference of the passive rotary shaft body 3; and a nearly cylindrical drilled-soil-scattering-proof cover 6 fitted on the outer circumference of the spiral body 5.

PROBLEM TO BE SOLVED: To prepare a mulch sheet for farming that retains both of water absorption properties and waterproof properties simultaneously as opposing properties from each other and shows excellent surface whiteness and biodegradability. SOLUTION: This mulch sheet for farming is composed of two layers, a water-absorbing layer and a water-retaining layer. The water-absorbing layer is formed by accumulating bleached and defatted cellulose fibers wherein the cellulose fibers are allowed to mutually entangled thereby the shape of the layer is retained. Meanwhile, the water-retaining layer is formed by accumulating un-defatted (raw) cellulose fibers and the un-defatted cellulose fibers are allowed to mutually entangled thereby the shape of the layer is retained. Further, the interlayer between the water-absorbing layer and the water-retaining layer is so formed as to entangle the defatted fibers and the defatted fibers to be unified. In the mulch sheet for farming, the water-absorbing layer is arranged on the sunshine side and the water-retaining later on the soil side and layered on the soil, for example, roots of fruit trees.

PROBLEM TO BE SOLVED: To provide a puff containing powder excellent in the peel strength of a seal part. SOLUTION: The puff containing the powder is composed by housing a cotton fiber group 6 and the powder 7 inside a bag 1 constituted of a nonwoven fabric 2. The nonwoven fabric 2 is constituted of cotton fibers as constituting fibers and openings having a size large enough to let the powder pass therethrough are provided. For the bag 1, the seal part 3 is provided on at least one end edge. The seal part 3 is formed by laminating the nonwoven fabric 2, the cotton fiber group 6 and the powder 7 and the nonwoven fabric 2 in this order and compressing them. Since cornstarch powder is contained in the powder 7, the peel strength of the seal part 3 is hard to decline. It is preferable that the average grain diameter of the cornstarch powder is about 9-18μm. Also, it is preferable that the content of the cornstarch powder is about 1-10 wt%.
