Problems solved by technology

However, because fibers with shorter length and thicker fineness usually have lower yarn strength, the strength of the product is too low after untwisted or low-twisted production, and the performance of the product is limited; and because the fibers are thick and short, there are many fiber ends and It is easy to be exposed, and the simple untwisted or low-twisted yarn structure will cause shortcomings such as puncture and fluffing, so there has been no report of processing this kind of fiber into untwisted or low-twisted fabrics so far

preparation example Construction

[0033] figure 2 It is a schematic diagram of the preparation method of the yarn of the present invention. As shown in the figure, at first, the primary twist twist a is applied to the sliver A, and the twist direction can be Z direction or S direction; and the water-soluble vinylon B1 is combined with a fine-denier chemical fiber filament B2 to form a sliver B, and the The sliver B can be untwisted, or the initial twist twist b is applied, and the twist direction is the same as that of the sliver A; then the sliver A and the sliver B are combined and reverse twisted, and the double twist twist applied by the reverse twist is c, thus obtaining the yarn C of the present invention.

[0034] image 3 The structure of the yarn in the fabric after the weaving process is shown. As shown in the figure, after the water-soluble vinylon B1 is dissolved by the fiber removal process, the fine-denier chemical fiber filament B2 is wound on the sliver A to form a bundled structure, and th...

Embodiment 1

[0037] Example 1: Preparation of untwisted crepe fabric from ramie / cotton blended yarn

[0038] Sliver A is ramie / cotton 50 / 5032s yarn with 600 twists / m and the twist direction is Z direction; A side-by-side body of polyester FDY (B2), untwisted (b=0). The sliver A and the sliver B are combined by a doubling machine and wound on the endless metal bobbin, and then 600 twists / m are applied by a two-for-one twister, and the twist direction is S twist. The yarn C thus obtained adopts the general warping, weft winding, and air-jet loom weaving process. After the gray cloth is obtained, it is washed at 90°C for 30 minutes in an overflow dyeing machine with a bath ratio of 1:25. Then clean it, and then enter the conventional dyeing and finishing process, and give sufficient overfeeding and weft shrinkage in the shaping process, and finally make a fabric with special wrinkles in appearance, good elasticity in warp and weft, and soft hand feeling, which is especially suitable for It ...

Embodiment 2

[0039] Embodiment 2: prepare low-twisted woolen fabric by wool / polyester blended yarn

[0040] In order to use thicker wool to achieve a better hand feel and provide good elasticity, 64 wool tops are used to spin wool / polyester 70 / 3034Nm yarns with a twist of 550 twists / m, Z direction (sliver A), and 85°C water-soluble 14.6tex water-soluble vinylon yarn and a 50dtex / 24fPTT filament, twist 400 twist / m, Z direction (sliver B). Sliver A and sliver B are combined by a doubling machine, and then 400 twists are added by a two-for-one twister, S-direction (thereby making sliver C), and the warping, weft winding and arrow shaft are carried out after 24 hours of fixed twisting After weaving on a loom, after the gray fabric is made, it is firstly de-dimensionalized in an overflow dyeing machine at a bath ratio of 1:30 at 90°C×25min, and then conventional wet and dry finishing is performed. In the setting process, a large warp and weft tension is applied so that no wrinkles appear on th...

Abstract

The invention provides a yarn for preparing a fabric with a bundling structure and a preparation method thereof. The yarn is prepared by the doubling and back twisting of a sliver A and a sliver B, wherein a first twist of the sliver A is a, the sliver B does not have a twist or has a first twist b, and a second twist of the back twisting is c. The yarn is characterized in that: the sliver B is a conjunct of water soluble vinylon and a fine denier chemical fiber long yarn. The preparation method of the yarn comprises the following steps of: applying the first twist a to the sliver A; combining the water soluble vinylon with the fine denier chemical fiber long yarn to form the sliver B, and not twisting the sliver B or applying the first twist b to the sliver B, wherein the twisting direction is the same as that of the sliver A; and doubling the sliver A and the sliver B on a doubling and twisting machine and then performing back twisting on a two-for-one twisting machine to obtain the yarn, wherein the second twist c is applied during the back twisting. When the yarn of the invention is used to prepare the fabric, the water soluble vinylon is dissolved by a vinylon dissolving process, the sliver A does not have a twist or has a low twist, and the fine denier chemical fiber long yarn is wound on the sliver A to form the bundling structure.

Description

technical field [0001] The present invention relates to a yarn and its preparation method. In particular, untwisted or low-twisted fabrics with bundled structures can be produced using the yarns of the invention. Background technique [0002] In recent years, with the continuous improvement of people's requirements for fabric comfort and the continuous development of textile technology, the development of untwisted or low-twisted fabrics has attracted more and more attention from fabric designers. [0003] Compared with ordinary fabrics, untwisted or low-twisted fabrics have the advantages of fluffy, soft, good air permeability and strong comfort. At present, the yarns for preparing untwisted or low-twisted fabrics are mainly made of single yarns spun from cotton fibers and single yarns spun from water-soluble vinylon fibers, which are reversely twisted after plying. In order to make the final untwisted or low-twisted fabric fluffy and soft, the raw material grade of the y...
