Problems solved by technology

The residual torque of Siro composite yarn is relatively large, and problems such as weft skew and poor anti-friction performance are prone to occur in fabric processing such as knitted fabric production
The Sirofill composite yarn also has a large residual torque, and the surface-coated short fibers are easy to slip due to the separation of the filaments and short fibers
During the weaving process, friction between healds, reeds and adjacent yarns can easily lead to fluffing and pilling of surface-coated short fibers, which directly affects processing efficiency
Although the Solo spinning technology can form a yarn structure similar to strands, this technology requires high precision in equipment modification. Fiber breakage is prone to occur during the fiber sliver splitting process, which affects the quality of the yarn, and production is relatively difficult.

Embodiment 1

[0030] Embodiment 1, the composite structure yarn of cotton fiber coating polyester filament (monofilament)

[0031] Such as figure 1 (a), (b), figure 2 Composite yarn patterns shown in (a) and (b), the yarn is made by Figure 5 and Figure 5A In the process shown, on the cotton spinning ring spinning frame, the cotton fiber roving sliver a is unwound from the roving bobbin, passed through the guide horn 1 and fed into the drafting zone by the back roller 2, and three polyester filaments (12D / 1F ) b, b', b" are respectively guided by the positioning wire guide mechanism and fed in parallel from the rear end of the front roller 5 at a distance of 0.5mm. Port 6 converges, and the three filaments b, b', b" are all located within the width boundary of the roving strands (see Figure 6 ), after drafting, the cotton roving strip a and filaments b, b', b" are output from the front jaws and enter the twisting triangle area, and the composite yarn 8 formed after twisting is wound ...

Embodiment 2

[0033] Embodiment 2, make the composite yarn that polyester filament (monofilament) wraps cotton short fiber

[0034] Such as image 3 (a), (b), Figure 4 Composite yarn patterns shown in (a) and (b), the yarn is made by Figure 5 and Figure 5A In the process shown, on the cotton spinning ring spinning frame, the cotton fiber roving sliver a is unwound from the roving bobbin, passed through the guide horn 1 and fed into the drafting zone by the back roller 2, and three polyester filaments (12D / 1F ) b, b', b" are respectively guided by the positioning guide mechanism and fed in parallel from the rear end of the front roller 5 at a distance of 2mm. 6 confluence. Wherein, the polyester filament b is located outside the width boundary range of the roving bar a, and the polyester filaments b' and b" are respectively located inside the width boundary range of the roving bar a (see Figure 7 ), after drafting, the cotton roving strip a and filaments b, b', b" are output from th...

Embodiment 3

[0036] Embodiment 3, making metal filament cotton fiber special yarn

[0037] With the continuous development of fiber processing technology, the processing technology of special yarn has become an important direction of textile processing. Fabrics made of special yarn are widely used in national defense, military industry, anti-static, anti-electromagnetic radiation and other fields. At present, the special yarns are mostly blended, and the ingredients are mostly polyester, cotton, metal fibers, etc. This example uses metal filaments and cotton fibers as raw materials to process special composite yarns of metal filaments and cotton fibers.

[0038] Such as figure 1 (a), (b), figure 2 Composite yarn patterns shown in (a) and (b), the yarn is made by Figure 5 and Figure 5A In the process shown in the figure, on the cotton ring spinning frame, the cotton fiber roving strand a is unwound from the roving bobbin, passed through the guide horn 1 and fed into the drafting zone...

Abstract

The invention relates to filament short-fiber composite yarn with a novel structure, which is formed by compositely twisting filament and short fiber. The yarn is characterized in that the filament in the yarn is generally three or more than three monofilaments or multifilaments which are respectively and dispersedly distributed and form organic combination with short fiber. According to the distribution position of the filament and short fiber in the cross section of the yarn, the composite yarn can be of a structure that the filament is coated by the short fiber or of a structure that the filament is distributed both inside and outside and short fiber is coated by the filament and short fiber on external faces. The filament can be silk, chemical fiber filament or metal wire, and the short fiber can be natural fiber or chemical short fiber. The invention has the advantage of increasing the strength, wear resistance, flexural rigidity and the like of the yarn. The composite structure yarn can be used for dress and clothes and special type yarns, and has the advantages of convenient and fast processing and both the properties of the filament and the short fiber.

Description

technical field [0001] The invention relates to a composite yarn of filament and short fiber with a new structure. The composite yarn is formed by composite twisting of at least three filaments and short fibers. The filaments are distributed in the short fibers and form an organic bond with the short fibers. combined. Yarn can be used to make clothing and accessories, and can also be used for special yarns. Background technique [0002] Both natural fibers and chemical fibers have their own advantages and disadvantages. It is difficult for a single type of fiber and a single structure of yarn to overcome the shortcomings of the fiber itself. The composite yarn composed of different raw materials can maximize the excellent characteristics of different fiber raw materials. , and make up for the deficiency of different fibers to the greatest extent, and the structure of the composite yarn can also endow it with more excellent qualities. Filament and staple fiber multi-yarn ca...
