And be preferably, at least with the 7 interval c1 that contact that weave cotton cloth, be provided with above-mentioned guiding walls 36,36 make the guiding stream 38,38 become negative pressure state.Thus, in guiding stream 38,38, by the air-flow that takes place towards above-mentioned attraction mouth 11, directly or indirectly become negative pressure state, the 7 in-house soakage waters of weaving cotton cloth outside the water droplet on 7 surface of weaving cotton cloth, the influence that is subjected to negative pressure is drawn out in the guiding stream 38,38, is transported to by said flow to attract mouthfuls 11 and be removed.In other words, open and become the above-mentioned guiding stream 38,38 of negative pressure state in 7 sides of weaving cotton cloth, play a part equally with above-mentioned attraction mouth 11, draw the water of infiltration from 7 sides of weaving cotton cloth.And, by as the guiding stream 38,38 of above-mentioned extension, increased in fact between 7 the suction zone of weaving cotton cloth, compared with the past, can increase more during the suction function of weaving cotton cloth, thereby increase water removal more weaving cotton cloth.
To this, at interval c2, because of guiding stream 38,38 be opened in weave cotton cloth 7 with the space of 30 of thin slices, the space flow into the air-flow of guiding stream 38 so increased from then on.By the increase of air-flow, 7 the water droplet of weaving cotton cloth more successfully is transported to and attracts mouthful 11 sides, is drawn into by weave cotton cloth 7 in-house yarn and the gap between yarn to attract mouthfuls 11.
And in example shown in Figure 3, to the interval b of thin slice 30 contacts, the interval c1 that ins succession is provided with interval e, and this interval e is as guiding walls 36,36 non-existent above-mentioned the 3rd intervals.More particularly, thin slice 30, the place ahead in the downstream of interval c1 direction is provided with interval e, be provided with the above-mentioned interval c1 of guiding walls 36,36, its terminal point v strides across and attracts mouth 11 to be positioned at than attracting more downstream of mouth 11, and above-mentioned interval e, with above-mentioned terminal point v as starting point, will be mouthfuls 11 that sow discord more from attracting, the peripheral part of suction pipe 13 with weave cotton cloth 7 positions of sowing discord as terminal point r.Thus,, be provided with the terminal point v of interval c1 as its starting point and the position r that will more sow discord from above-mentioned attraction mouth 11 interval e as its terminal point at thin slice 30, at interval e, sheet plane 35 and weave cotton cloth 7 and weave cotton cloth 7 and the peripheral part of suction pipe 13 be configured to contact.
Sheet plane by interval e with weave cotton cloth and weave cotton cloth and the contacting of suction pipe, can suppress the air-flow that flows into from this interval.For example compare with the mode that does not have interval e, attract mouthfuls 11 negative pressure more the concentrated area to the interval c1 and the interval c2 work of the upstream side that is positioned at interval e, thereby the throughput in the increase guiding stream 38,38 and the degree of negative pressure, and the water removal of increase to weaving cotton cloth.
Represent 1 experimental data when above-mentioned de-watering apparatus is useful in the water jet loom of our company at Fig. 8.Following data are, change some thin slices 30 and attract the ability of air blast, and estimate the experimental result data of 7 the water removal effect of weaving cotton cloth.And, be the water jet looms of our company as the water jet loom of prerequisite, the goods form of loom is zw408, the nominal reed width is 340cm, use warp thread to twist with the fingers Z800T/m as polyester 75dtex/24f, use weft yarn to twist with the fingers Z800T/m as polyester 84dtex36f, it is 450rpm that loom rotates number.And, sow discord device about carbonated drink, used the instrument that keeps buoy in so-called in the mechanism of the water that eliminating is sowed discord.
And, thin slice used thickness 1mm have the transparency plastic tab, about thin slice in the past product (the smooth sheet plane that does not promptly have guiding walls) be thin slice A, the present invention's product are thin slice B.And, attracting the vent in the sides of a garment mouth width of cloth of mouth 11 is about 5mm, to this, setup parameter as the thin slice 30 of this part invention, the height t 1 of guiding walls and the thickness p2 of guiding walls are made as 0.5mm respectively, and the guiding walls arrangement pitch p1 of adjacency is made as 1.5mm, and siding-to-siding block length c is made as 40mm, and intersecting angle θ 1 is 90 °.And, about attracting air blast, selectively installed and used very general workload 750w and the air blast of 400w.And, on the degree that the dewaters hurdle of Fig. 8, represented that percher author will be by the residual degree of 7 the moisture of weaving cotton cloth behind the suction pipe 13, the result who estimates objectively through three phases, on the overall merit hurdle, the above-mentioned degree that dewaters, and fabric quality or attract the key elements such as consumption electric power of air blast have been represented to consider, the result who estimates through three phases.
