Problems solved by technology

This method requires three strands to be fed, and it is difficult to feed on the original ring spinning frame, or the feeding mechanism needs to be modified. At the same time, the feeding of three strands also increases the drafting burden of the drafting mechanism, or makes the drafting mechanism not Adaptation, affecting the quality of sliver (core yarn)

Embodiment 1

[0034] Use the equipment described in the present invention, and spin the core-spun yarn that 11.8tex polyester / cotton staple fiber covers cotton staple fiber according to the spinning short fiber / short fiber core-spun yarn method of the present invention. The process parameters are mainly as follows: the cotton fiber of the outer cladding layer has a long length, high count, and good maturity of combed cotton sliver, the main length of the fiber is 30mm; the polyester staple fiber of the core layer is selected as a cotton-type fiber with a length of 38mm, and the blending ratio is designed as Polyester / cotton = 49 / 51; the total draft ratio is designed to be 60 times; the tension draft from the front roller to the front roller is selected to be 1.3 times; the spinning twist coefficient is designed to be 300.

[0035] The polyester / cotton staple core-spun yarn spun in this example has a coverage rate of 96% and has good peeling resistance.

Embodiment 2

[0037] Use equipment described in the present invention, spin the core-spun yarn that 23.62tex cotton staple fiber is coated with polyester filament according to the spinning filament / short fiber core-spun yarn method of the present invention. The process parameters are mainly as follows: carded sliver with a main body length of 29mm is used for the outsourcing cotton fiber, and 75 denier polyester is selected as the core chemical fiber filament; The draft ratio E between is based on E=πD 1 / D 2 (=0.0987π / 0.0156) calculated by the formula is 1.987. The spinning twist coefficient is designed to be 320.

[0038] The polyester filament core-spun yarn covered with cotton staple fibers spun in this embodiment has a covering rate of 95% and has good peeling resistance.

Embodiment 3

[0040] Use equipment described in the present invention, in conjunction with short fiber / short fiber core-spun yarn method and filament / short fiber core-spun yarn method of the present invention, spinning polyester filament / viscose staple fiber / cotton fiber three-layer bag core yarn.

[0041] In this embodiment, the core yarn filament is selected from 50-denier polyester, the viscose is selected from 38mm cotton-type fiber carded slivers, the cotton fiber is the same as in Example 2, and other relevant process parameters are the same as in Example 2. The process is to implement the two staple fiber strips of viscose staple fiber / cotton fiber according to the method described in Example 1, and implement the polyester filament according to the method described in Example 2, and make the polyester filament be output together with it. The middle positions of the two staple fiber strands are twisted together outside the leading jaws to obtain a three-layer core-spun yarn of core ya...

Abstract

The invention relates to a core spun yarn device and the preparing method. The device comprises three roller extension devices or four roller extension devices. The invention is characterized in thatthe front part of the front roller of the extension device is provided with a super front roller; the super front roller is provided with a super front plastic revolve with a round direction groove; the super front roller and the super front plastic revolve forms the super front plier which is arranged on the same horizontal plane of the extension plier; the distance between the super front plierand the extension plier can be adjusted; a strip positioning device is arranged between the front roller and the super front roller; the positioning device is provided with two grooves which are parallel arranged on the fixed pole; the fixed pole is arranged on the roller base; the installationsite of the positioning device makes the soleplate of the groove in the same horizontal plane with the extension plier and the super front plier; one of the groove is matched with the round direction groove in the output direction; and the installationsite is adjustable.

Description

technical field [0001] The invention relates to textile technology, in particular to a device and method for spinning core-spun yarn with a ring spinning machine. technical background [0002] Core-spun yarn is a yarn with a layered structure of core yarn and outer fiber. The core yarn (core layer) and outer fiber (wrapping layer) of the core-spun yarn generally use different types of fibers. This design can give full play to the strengths of the two different fibers and make up for their respective deficiencies. At present, the core-spun yarn spun on the ring fine sand machine is mainly filament / short fiber core-spun yarn, and the core yarn is generally filament, and the short fiber is outsourced; there is also the opposite core-spun yarn design, that is, the filament is used as the outer fiber , wrapped staple fiber core yarn. But this core spun yarn has fewer uses. [0003] There are mainly the following technical routes for spinning core-spun yarn: one is to place th...
