Description

Technical Field

[0001] The invention relates to the technical field of textile yarns, and more particularly to a production device and a production process for mixed-color core-spun colored porcelain yarns. Background Art

[0002] Core-spun yarn has a production history of more than 40 years since the mid-1960s. Core-spun yarn, also known as composite yarn or covered yarn, is a new type of yarn composed of two or more fibers. The birth of core-spun yarn products caters to the market's demand for clothing that is moisture-absorbent, breathable, shape-retaining, stretchable, and free of oppression and restraint. It has been widely used in various types of clothing, such as swimwear, gymnastics suits and other close-fitting sports series; such as pantyhose, rabbit sweaters, wool yarn and other home series; such as jackets, shirts, jeans and other leisure series. Core-spun yarn has more obvious advantages in the field of mixed color spinning:

[0003] 1) Yarn is no longer dyed, and the subsequent production process is shortened, which is easy for customers to accept;

[0004] 2) The yarn strength is increased, and the production efficiency of both customers and me is improved to a certain extent;

[0005] 3) It can make full use of the advantages of each component to meet the requirements of different fabrics for yarn (such as natural fibers covering the periphery of the yarn can provide a comfortable feel and a satisfactory appearance);

[0006] 4) Relatively low-cost chemical fibers can be used to achieve higher levels of yarn strength, elasticity, quick-drying and other related properties;

[0007] 5) Functional filaments can be used to realize the functionalization of yarn products, such as moisture absorption and quick drying, antibacterial, anti-ultraviolet, etc.;

[0008] 6) Colored filaments can be used to achieve a fashionable appearance of yarn products;

[0009] 7) The yarn fabric spun by this technology can better improve the anti-pilling performance of the fabric;

[0010] 8) It can reduce the proportion of dyed fibers used, which is not only environmentally friendly, but also conducive to improving the spinnability of colored polyester varieties.

[0011] However, the core-spun yarns on the market have always been natural yarns and are used for weaving. The application of core-spun yarn production technology to mixed-color spinning production is almost blank. This is because: the key to applying conventional core-spun yarn technology to color spinning is to determine whether the yarn can completely cover the core fiber, because there is no dyeing process after color spinning, and the fibers that cannot be covered (called dew or core) cannot be compensated by dyeing in the same bath; secondly, it is necessary to solve the problem of the horizontal quality of spindle difference and platform difference. The uneven weight of the roving, the positioning of the roving, the tension change and position of the core fiber, the drafting difference between the spindles or platforms, etc. are all the differences that cause the local covering effect, thereby forming the different color or effect of the yarn; and then there is the problem of the dew tail formed by the self-winding joint.

[0012] Therefore, providing a mixed color spun core-spun colored porcelain yarn production device and production process is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0013] In view of this, the present invention provides a mixed-color core-spun colored porcelain yarn production device and production process, which overcomes the problems of difficult spinning consistency and self-winding joint dewlapping of the original mixed-color core-spun yarn products, and achieves a special coated appearance effect when the core yarn is half-wrapped or intermittently coated.

[0024] 4) The filament B passes through the yarn guide hook and the tension disk through the tension control device, and then passes through the front and rear guide wheels on the cradle along the surrounding arc of the front leather roller to the rear jaw of the front roller;

[0025] 5) The roving A and filament B are fused at the rear jaw of the front roller and the core-spun yarn is output.

[0026] Furthermore, the raw material of the roving A is one or more of cotton, polyester, viscose, wool and linen.

[0027] Further, the basis weight of the roving A is 2 g / 10 m to 8 g / 10 m.

[0028] Furthermore, the filament B is polyester filament or nylon filament or spandex filament or vinylon filament.
