Problems solved by technology

[0007] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a cotton-type stretch-cut staple fiber strip suitable for direct drawing processing, so that low-strength fibers can avoid carding machine processing and directly enter and draw. Strip processing, so as to solve the spinning problem of low-strength fibers such as chitosan and seaweed fiber. The method of drawing and cutting cotton-type fibers

Embodiment 1

[0031] Such as figure 1 Shown, a kind of stretch-cut strip making method of cotton-type fiber is characterized in that, comprises the steps:

[0032] (1), prepare the tow to be drawn and cut:

[0033] (1), lead the tow to be stretched and cut into strips from the tow box;

[0034] (two), tension balance

[0035] The tow to be drawn from the tow box is fed to a tension equalization device composed of several pairs of tension rollers arranged up and down to balance the tension of each filament bundle and each filament in the filament bundle.

[0036] (3) Spreading treatment

[0037] In the above-mentioned stretch-cut sliver-making method for cotton-type fibers, the tow to be stretch-cut slivered drawn out from the tow box is fed by a spreader with spiral convex strips extending from the middle to both sides on one or more surfaces. Spreading rollers composed of rollers can gradually spread each filament in the filament bundle within a certain width under the action of the sp...

Embodiment 2

[0047] Such as figure 1 Shown, a kind of stretch-cut strip making method of cotton-type fiber is characterized in that, comprises the steps:

[0048] (1), prepare the tow to be drawn and cut:

[0049] (1), lead the tow to be stretched and cut into strips from the tow box;

[0050] (two), tension balance

[0051] The tow to be drawn from the tow box is fed to a tension equalization device composed of several pairs of tension rollers arranged up and down to balance the tension of each filament bundle and each filament in the filament bundle.

[0052] (3) Spreading treatment

[0053] In the above-mentioned stretch-cut sliver-making method for cotton-type fibers, the tow to be stretch-cut slivered drawn out from the tow box is fed by a spreader with spiral convex strips extending from the middle to both sides on one or more surfaces. Spreading rollers composed of rollers can gradually spread each filament in the filament bundle within a certain width under the action of the sp...

Abstract

The invention discloses a cotton type fiber stretch-breaking strip making method, which comprises the following steps that (1) tows requiring stretch-breaking strip making are prepared; (2) stretch-breaking strip making treatment is carried out: 1) the tows led out from a tow box are fed into a stretch-breaking device provided with four stretching regions and four groups of stretch-breaking rollers, and first-time stretch-breaking processing is firstly carried out through a first stretch-breaking region; 2) the tows subjected to the first-time stretch-breaking processing enter a second stretching region for second stretch-breaking processing; 3) the tows subjected to the second stretch-breaking processing enter a third stretching region for third stretch-breaking processing; 4) the tows subjected to the third stretch-breaking processing enter a fourth stretching region for fourth stretch-breaking processing; (3) coiling processing is carried out. The method has the advantages that cotton type short fiber strips can be directly manufactured, and the severe carding effect of a cotton carding machine can be avoided, and the cotton type short fiber strips can be directly mixed with other fiber strips in the drawing work procedure.

Description

technical field [0001] The invention belongs to the technical field of textile engineering, and in particular relates to a stretch-cut strip-making method for cotton-type fibers. Background technique [0002] With the rapid development and popularization of chemical fibers (hereinafter referred to as chemical fibers), there are more and more varieties and specifications. According to its main components, it can be divided into: polyester, nylon, acrylic, vinylon, polypropylene, spandex, chlorine fiber, aramid fiber, viscose fiber, etc. According to its length specifications, it can be divided into: filament and short fiber. In the short fiber, according to the length distribution characteristics, it can be divided into: equal length fiber and different length fiber. [0003] Isometric fibers are usually made by a special cutting machine. The length of the fibers is equal, and there are cotton-type staple fibers and medium-length fibers. Cotton-type staple fiber has variou...
