JPS61289136A - Production of fancy twisted yarn of semi-worsted yarn - Google Patents

Abstract

PURPOSE:To obtain the titled twisted yarn from which no fancy yarn falls out of base yarn, by feeding roving for fancy yarn to at least one position of a drafting process, cutting the roving to form naps, etc., and entangling yarn of sliver with the naps, etc. CONSTITUTION:A drafting device of Gill type is used as the drafting device 8, the plural slivers 6 and the roving 12 for fancy yarn are fed to drafting device, the roving 12 for fancy yarn is cut in a flaky or nap state by the drafting force at the drafting device and the slivers are entangled with the yarn of the roving 12 for fancy yarn. The slivers and the roving for fancy yarn may be fed to the drafting device of a fine spinning frame.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is directed to semi-& woolen yarn containing flakes or neps, suitable for use in carpets, sweaters, side cloths, etc.
That is, the present invention relates to a method of producing cicada hair ornament twisted yarn.

(Prior art) Conventionally, as a method for producing decorative twisted yarn using the semi-FF1 wool method, the present applicant et al. previously applied for a method in which flakes or neps (hereinafter referred to as neps, etc.) are consolidated with condensation oil. Solidified nep etc. are blended with base fibers to form a sliver from the blended cotton, the sliver is homogenized by repeated doubling and drafting, and then spun using a spinning machine (Japanese Patent Publication No. 58-5104
Publication No. 5).

(Problems to be Solved by the Invention) In the conventional method, the sliver was formed after the neps, etc. were mixed with the base fiber, and the neps, etc. were arranged due to the carding action in the sliver forming process. Moreover, since the NEP is solidified with a uniformly solidified oil, the entanglement with the base fibers is performed as a whole, such as the NEP, and the enveloping force between the fibers is not very strong, so a strong pulling force is exerted on the NEP, etc. This may cause hair loss.

(Means for Solving the Problems) The present invention is an improvement on the conventional example described above, in which fibers such as NEP and base fibers are entangled more firmly, and the sliver homogenization process or Of the drafting steps carried out several times during the spinning process, roving for decorative twisting is supplied together with the sliver in at least one drafting step, and the roving is divided during the drafting operation to form nep or the like. It is characterized by having NEP etc. entwined with the fibers of the sliver.

(Function) In the present invention, since the roving is divided by the drawing action during the drafting operation to form neps, etc., the fibers at the broken ends of the formed neps are disordered.
It becomes deeply and strongly intertwined with the i-fibers of the sliver.

(Example) The drawings show an example of the method of the present invention, in which FIG. 1 is a schematic diagram of a draft device in a sliver homogenizing step, and FIG. 2 is a schematic diagram of a sliver forming step.

The manufacturing process of semi-flocked decorative twisted yarn includes a sliver forming process in which a sliver is formed from raw wool, a sliver homogenizing process in which the sliver formed in the sliver forming process is homogenized by repeating doubling and tying, and a sliver homogenizing process. It consists of a spinning process in which the sliver is passed through a spinning machine and formed into roving.

In the sliver forming process, the pretreated raw wool stored in the hopper (1) is passed through a presto (2), a cylinder (3), a walker (4), and a dofa (5) in order to form a web. The web is focused to form a first sliver (6), which is placed in a coiler box (7).

In the sliver homogenization step, a step (
By repeating the process of doubling and drafting several times, a second sliver (9) is obtained in which the fibers in the sliver are aligned and their thickness is thinned and homogenized.

In the spinning process, the second sliver (9) obtained in the sliver homogenization process is spun IS! ! (10) to give a twist and form a roving (11).

In this embodiment, as shown in FIG. 1, a gill-type draft device is used as the draft device (8) in the sliver homogenization process, and the first draft device (8a) is used with a plurality of first slivers (6) and a decorative The roving for yarn (12) is supplied, and the roving for decoration (12) is broken into 7 rake shapes or nep shapes by the drawing force of the drafting device (7a), and the roving for decoration (12) is The fibers are intertwined with the fibers of the sliver.

The roving (12) for the decorative yarn may be supplied to any of several draft devices (8) during the sliver homogenization process.

FIG. 3 shows another embodiment of the present invention, in which decorative light roving is supplied during the spinning process, the spinning frame (10) is a draft ring spinning frame, and the spinning machine (10) is a draft ring spinning machine. spinning fi (
10) into the draft device (13) of the second sliver (9)
At the same time, the roving for decorative light (12) is supplied, and the roving for decorative light (12) is divided into 7 rake shapes or nep shapes by the drawing force of the draft device (13). ) are entwined with the i-fibers of the sliver.

(Effects of the Invention) As described above, in the present invention, the decorative roving is supplied together with the sliver to the sliver homogenization process or the drafting process in the spinning process in the semi-stacking type spinning method, and the drafting device This may be due to the fact that the roving for decorative yarn is made brighter by using the stretching force of Since the fibers of the decorative thread are deeply and firmly intertwined with the fibers of the sliver, the decorative thread will not come off from the base fiber (sliver) even if a pulling force is applied to the decorative thread.
