Abstract

PURPOSE:To obtain a method for producing unconventionally uniform conjugate yarn in a previously unknown form of twisted union yarn. CONSTITUTION:Respective rovings (A), (B) and (C) composed of three kinds of materials are fed from back rollers 1 of a spinning frame at an interval, drafted then and spun from front rollers 3. In the process, three fleeces (a), (b) and (c) are delivered in a separate state of the respective intervals of 1-2mm. The three fleeces (a), (b) and (c) are subsequently joined, twisted at a twist coefficient within the range of 3.8-4.2 (using the English cotton count) and then wound.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a composite yarn composed of three kinds of materials for use in various clothes by using a cotton spinning type spinning machine.

[0002]

2. Description of the Related Art Conventionally, as a method for producing a composite yarn,
A general method is to use a twisting machine to twist a plurality of yarns (spinning yarns) made of different materials into a yarn.

In recent years, there has been proposed a method for producing a composite yarn by twisting together rovings made of two different materials in a spinning process and spinning them.

[0004]

However, in the former method, since the spun yarn has to be twisted by twisting the spun yarn, the twisting process is added to the spinning process, and one process is added, resulting in an increase in manufacturing cost. There was a problem.

Further, the latter method is a method which is currently being manufactured in many cases, and is spun by a spinning machine while twisting two kinds of roving yarns of different materials and wound on a wood pipe. Along with the fluctuation in the vertical direction and the fluctuation in the winding thickness, the twist angle and twist tension are slightly different, and the twist pitch also changes. In addition, it is difficult to obtain a uniform composite yarn because the roving unevenness directly affects the twisted thickness.

The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to provide a method for producing a uniform and unprecedented intertwisted yarn-like composite yarn at low cost. Is.

[0007]

Means for Solving the Problems The present invention achieves the above object, and supplies each roving composed of three kinds of materials at intervals from a back roller of a spinning machine, and after drafting, When spun from the front roller, the three fleeces are sent with a distance of 1 to 2 mm between them, and then the three fleeces are combined and the twist coefficient (using English cotton count) 3.8 to 4.2 The method for producing a composite yarn is characterized by twisting and winding in the range of.

[0008]

In the present invention, when each roving consisting of three kinds of materials is supplied from the back roller of the spinning machine at a distance, drafted, and then spun from the front roller,
By setting the spacing between the three fleeces to an appropriate spacing of 1 to 2 mm and twisting the twist coefficient (using English cotton count) in the range of 3.8 to 4.2, the winding position on the wood pipe can be adjusted. Regardless of fluctuations, almost 10% of the set number of twists is applied to each fleece while being hardly affected by the twisting of the three fleeces, and at the same time, a mixed single yarn composite Yarn is obtained. The obtained composite yarn can be dyed in different colors to obtain a uniform twisted and knitted yarn in the form of a mixed twisted yarn.

[0009]

The present invention will be described in detail below with reference to the illustrated embodiments.

In FIG. 1, reference numeral 10 denotes a normal spinning machine equipped with a back roller 1, a cradle 2, a front roller 3, a snell wire 4, a wood pipe 5, a ring 6 and a traveler 7. Three rovings A, B, made of different materials
C is supplied in parallel from the back roller 1 at a predetermined distance, and is drafted so as to have a predetermined thickness with the front roller 3 via the cradle 2 and, as shown in FIG. After adjusting the distance at 8 and supplying it to the front roller 3, after sending it out from the front roller 3 as three fleeces a, b, c so that the inner distance L between them is in the range of 1 to 2 mm. , Each fleece a,
b and c are twisted, passed through the snell wire 4, passed through the traveler 7, and twisted and wound on the wood pipe 5 within a twist coefficient of 3.8 to 4.2.

It is necessary to set the inner spacing L to be in the range of 1 to 2 mm. If the inner spacing L is less than 1 mm, a uniform composite yarn cannot be obtained, and if it exceeds 2 mm. Has a problem of frequent yarn breakage when spun from the spinning front roller because the spacing is too wide.

The twist coefficient is required to be 3.8 to 4.2,
Normal twist factor, especially for normal knits 3.2
In the case of up to 3.4, yarn breakage occurs frequently, which causes many problems.

Next, a specific embodiment of the present invention using the spinning machine shown in FIG. 1 will be described.

Concrete Example Acrylic Short Fiber 1.5d × 35 mm, Polyester Short Fiber 1.
Using 0dx38mm and 1.28dx38mm cotton material, 100% roving weight 100 gelen / 30yd roving was made, and these 3 roving threads were used for the back roller 1 of the spinning machine shown in Fig. 1. It is supplied at intervals, drafted between the cradle 2 and the front roller 3, sent out from the front roller 3 with a fleece spacing L of 1 mm, twisted with a twist coefficient of 3.8, and then number 30 (English cotton count). ) Composite yarn Y spun on wood tube 5
Rolled up.

The resulting composite yarn Y was knitted on a knitting machine 30 "gauge 28G and dyed differently so that the acrylic fiber and the cotton had different colors (the polyester fiber was left white). It was possible to obtain a completely novel three-kind mixed yarn without such uneven thickness thickness of twist and uneven twist pitch.

[0016]

Industrial Applicability According to the present invention, a composite yarn obtained with few yarn breakages and good spinning properties during spinning has no twist thickness unevenness and twist pitch unevenness as in the prior art, and is a completely new composite yarn. It is possible to obtain a yarn, and it is possible to obtain a twisted yarn which has never been obtained by dyeing different colors.
