Abstract
The invention relates to a weft yarn-assisted weft shrinkage prevention device for a jet loom. The weft yarn-assisted weft shrinkage prevention device is arranged at an air outlet end of a secondary air jet pipe of the jet loom and is used for controlling air pressure from the secondary air jet pipe. The device comprises an adapter tube (1) and a pressure reducer (2), wherein the pressure reducer (2) is a tow (21); one end of the tow (21) is fixed and the other end of the tow (21) is a free end; and the adapter tube (1) is fixedly connected with one end of the tow (21). The weft yarn-assisted weft shrinkage prevention device for the jet loom can make pressure of gas ejected by the secondary air jet pipe uniformly distributed to each filament of the tow, reduces gas pressure around a weft yarn of the secondary air jet pipe, improves the verticality of a spandex yarn and reduces the torsion resistance. Meanwhile, the spandex yarn in the weft yarn does not have a weft shrinkage phenomenon like a nylon yarn, and the woven fabrics have smooth, flat and beautiful surfaces.
Description
(1) technical field
The present invention relates to a kind of air-jet loom, be specifically related to the auxiliary anti-looped weft device of a kind of weft in jet looms.Be installed on the outlet side of the secondary air jet pipe of air-jet loom.Be used to control out the air pressure of secondary air jet pipe.Belong to technical field of textile machine.
(2) background technology
The warp thread of cotton bright and beautiful elastic force cloth adopts cotton yarn, and weft yarn adopts 40D polyamide fibre+20D spandex.Because there is the problem of resilience in spandex itself, the sending when Weft handling device is jet to be sent weft yarn in the past of air-jet loom, because jet air pressure is bigger, weft yarn separates easily, wherein not resilience of a 40D polyamide fibre, and the resilience of a 20D spandex produce distortion, cause looped weft.The cloth cover of the cotton bright and beautiful elastic force cloth after weaving like this will produce crude rough sensation.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of and can prevent that cotton bright and beautiful elastic force cloth from producing the auxiliary anti-looped weft device of weft in jet looms of looped weft in weaving process.
The objective of the invention is to realize like this: the auxiliary anti-looped weft device of a kind of weft in jet looms; Said device comprises that one takes over and a pressure reducer, and said pressure reducer is a tow, and an end of this tow is fixed; The other end is a free end, and said adapter is fixedly connected with an end of tow.
The auxiliary anti-looped weft device of weft in jet looms of the present invention, said tow becomes the structure of a writing brush head.
The auxiliary anti-looped weft device of weft in jet looms of the present invention can also be set with an outer tube outside said tow, said adapter is fixedly connected with an end of this outer tube.Be convenient to change the tow in the outer tube like this.
The invention has the beneficial effects as follows:
Adopt the auxiliary anti-looped weft device of weft yarn of the present invention, the pressure of the gas of secondary air jet pipe ejection is evenly distributed on each rhizoid of tow, the weft yarn air pressure on every side of using secondary air jet pipe diminishes; The perpendicularity of spandex yarn increases; Torsion resistance reduces, and the spandex yarn in the weft yarn is the same with polyamide staple fibre spun yarn can not to produce the looped weft phenomenon, and the cloth cover smooth surface that weaves like this is smooth beautiful; Can reduce simultaneously the consumption of weft yarn, energy savings.

(5) specific embodiment
Referring to Fig. 1, Fig. 1 is structure one sketch map of the auxiliary anti-looped weft device of weft in jet looms of the present invention.Can find out by Fig. 1; The auxiliary anti-looped weft device of weft in jet looms of the present invention comprises that one takes over 1 and one pressure reducer 2, and pressure reducer 2 is a tow 21; One end of tow 21 is fixed; The other end is a free end, and formation one is similar to the structure of writing brush head, and said adapter 1 is fixedly connected with an end of tow 21.
Referring to Fig. 2, Fig. 2 is structure two sketch mapes of the auxiliary anti-looped weft device of weft in jet looms of the present invention.Can find out by Fig. 2, the auxiliary anti-looped weft device of weft in jet looms of the present invention, its pressure reducer 2 structures can also be on the basis of Fig. 1, suit one outer tube 22 outside tow 21, said adapter 1 is fixedly connected with an end of this outer tube 22.Be convenient to change the tow 21 in the outer tube 22 like this.
Fig. 3 is the application implementation illustration intention of the auxiliary anti-looped weft device of weft in jet looms of the present invention.Can find out by Fig. 3, the auxiliary anti-looped weft device of weft in jet looms of the present invention in use, through take over 1 be installed in the secondary air jet pipe 4 of air-jet loom the outlet side, be used to control the pressure of the gas of secondary air jet pipe 4 ejections.
Said tow can adopt monofilament etc. to process.
