Problems solved by technology

[0004] For example, China's announcement number is that CN201411528Y discloses a kind of wing yarn fabric, and the yarn used is a fine denier polyester filament with a twist greater than 3000T / m, which basically makes up for the thicker yarn of the existing imitation silk material, less twist, Poor softness and other deficiencies
However, because this kind of yarn is relatively thin, it brings certain difficulties to the weaving process, and the use of the same fine denier polyester filament has the same shrinkage function, so the spun yarn has no velvet feeling, and the fabric made has a partial feel. stiff
[0005] It can be seen from the above patents that although the fabric woven from ordinary polyester filaments has the advantages of good strength, smoothness and crispness, and easy washing, it has the advantages of hard hand feeling, poor touch, soft luster, and breathability. Disadvantages such as poor sex and hygroscopicity
Compared with silk fabrics, the gap is even bigger, so the disadvantage of poor wearing performance must be eliminated by changing the structure of the silk or different heat shrinkage
[0006] In order to make up for the determination of the stiff hand feeling of the same polyester fiber, researchers have discovered a simulated silk that uses two different fiber composite yarns. For example, Chinese patent CN201110291854. Alternately arranged yarns and Chinese patent CN201110291858. It is disclosed that the bright triangular special-shaped polyester and cupro ammonia filaments are arranged alternately. Specifically, a part of polyester is replaced by cupro ammonia filaments. Using high-quality wood pulp and cotton linter pulp as raw materials, it is dissolved in cuproammonia solution of copper complex salt solution to make spinning solution. After mixing, filtering and defoaming, it can be breathable and sweat-absorbing. Still use natural high-quality wood pulp or cotton linter pulp, these natural pulps are less and less in nature, and there are many steps, and the production cost is relatively high

Embodiment 1

[0026] Such as figure 1 As shown, the manufacturing method of simulated silk polyester composite yarn consists of two types of fibers, 36dtex / 32f POY yarn and 18dtex / 18F FDY yarn, first passing through the fiber network device to generate network yarns with a network density of 50 pieces / m, and then Carry out Z-twisting processing to POY and FDY network yarn, the number of twists is 2600T / m (process a), and then carry out heat setting treatment (process b) to the composite fiber after twisting, the heat setting temperature time is 150 minutes, and the temperature is 97 ℃. Since the thermal shrinkage rate of POY yarn is significantly higher than that of FDY yarn, POY yarn shrinks and its length becomes shorter, causing FDY yarn to protrude, deform, and cover the surface of the composite fiber. Through the above processing, the imitation silk yarn has stable structure, good luster, sweat-absorbing and breathable, and has a velvet feel.

Embodiment 2

[0028] Such as figure 2 As shown, the manufacturing method of simulated silk polyester composite yarn consists of two types of fibers, POY yarn of 40dtex / 32f and FDY yarn of 20dtex / 18F, first passing through the fiber network device to generate network yarn with a network density of 60 pieces / m, and then Carry out S-twisting processing to POY and FDY network yarn, the twist number is 2800T / m (process a), and then carry out heat setting treatment (process b) to the twisted composite fiber, the heat setting temperature time is 100 minutes, and the temperature is 100 ℃. Since the thermal shrinkage rate of POY yarn is significantly higher than that of FDY yarn, POY yarn shrinks and its length becomes shorter, causing FDY yarn to protrude, deform, and cover the surface of the composite fiber. Through the above processing, the imitation silk yarn has stable structure, good luster, sweat-absorbing and breathable, and has a velvet feel.

Embodiment 3

[0030] Such as figure 2 As shown, a kind of imitation silk polyester yarn is composed of two types of polyester fibers, POY yarn of 50dtex / 32f and FDY yarn of 22dtex / 18f. POY and FDY network yarns are processed with S twisting, the twist number is 3000T / m (process a), and then the processed composite fibers are subjected to heat setting treatment twice (process b), the heat setting temperature time is 80 minutes, and the temperature is 105 ℃. Since the thermal shrinkage rate of POY yarn is significantly higher than that of FDY yarn, POY yarn shrinks and its length becomes shorter, causing FDY yarn to protrude, deform, and cover the surface of the composite fiber. Through the above processing, the imitation silk yarn has stable structure, good luster, sweat-absorbing and breathable, and has a velvet feel.

Abstract

The invention relates to an imitated silk and polyester composite yarn and a method for preparing the same. Composition is carried out on two types of fibers including pre-oriented yarns (POY) and fully drawn yarns (FDY) to obtain the imitated silk and polyester composite yarn. The method includes carrying out network, twisting and heat setting treatment on the two types of fibers and carrying outcomposition on the two types of fibers to obtain the imitated silk and polyester composite yarn. The imitated silk and polyester composite yarn and the method have the advantages that the imitated silk and polyester composite yarn is aging-resistant, is easy to wash and has drape feel; the imitated silk and polyester composite yarn with velvet feel and comfortable hand feel can be obtained by theaid of the difference of the heat shrinkage of the two types of fibers; the imitated silk and polyester composite yarn and the method are low in cost, and accordingly mass consumption can be facilitated.

Description

technical field [0001] The invention belongs to the field of yarn and its preparation, in particular to a synthetic silk polyester composite yarn and a preparation method thereof. Background technique [0002] With the improvement of living standards, modern people have higher and higher requirements for fabrics. A single polyester filament fabric can no longer meet the ever-changing market demand, and polyester imitation silk fabrics with special styles have emerged as the times require. However, most of the existing imitation silks are relatively stiff, with low yarn twist and poor softness, resulting in poor hand feeling or thicker fabrics, and there is still a certain gap with real silk fabrics, and the cost of real silk yarns is relatively high. Used in high-end clothing, the range is small, the sales volume is small, and there is a long distance from the mass consumers, and it is easy to age, not resistant to washing, easy to wrinkle and other disadvantages. And relat...
