Description

Technical Field

[0001] This invention relates to the field of knitting, and more specifically, to a method for preparing jacquard fleece single-sided fleece. Background Technology

[0002] In the prior art, such as the hollow thermal clothing fabric with application number 201720269364.9, there is a three-layer structure. However, the above technical solution still has the following shortcomings: due to its multi-layer structure, its thickness is generally about 4mm. Although it achieves warmth, the thermal clothing is fluffy and bulky, which is not convenient for movement and has poor comfort.

[0003] Due to the limitations of the loom during the weaving process, elastic fibers such as high-elasticity yarn cannot be added. Such fabrics do not have stretch, elongation and resilience. Summary of the Invention

[0004] The present invention aims to develop a novel design concept to solve the problem that elastic fibers such as high-elasticity yarn cannot be added during the weaving process due to the limitations of the loom, and to solve the problem of the existing fabrics being too heavy.

[0005] This invention provides a method for preparing jacquard fleece single-sided fabric, characterized in that: using DTY high-elastic yarn and Coolpass as raw materials, a reverse-wrapped computer jacquard structure knitted fabric is woven, which forms a textured visual effect.

[0014] Furthermore, the method for preparing jacquard fleece single-sided fleece provided by the present invention is further characterized in that:

[0016] Furthermore, the method for preparing jacquard fleece single-sided fleece provided by the present invention is further characterized in that:

[0017] The high-elastic yarn has a length of 16.2cm / 50N and a yarn consumption ratio of 46%.

[0027] The function and effects of this invention:

[0028] The main objective of this invention is to provide a jacquard fleece single-sided fabric, primarily for autumn and winter sports and leisure applications. The fabric contains special minerals that effectively absorb sunlight and convert it into heat energy, raising the fabric's temperature. The hollow cross-section reduces fiber weight and prevents heat loss, resulting in a lightweight, heat-retaining, and light-absorbing fabric that enhances wearing comfort.

[0029] Figure 1 Product renderings for this embodiment. Detailed Implementation

[0030] Example 1

[0031] Yarn selection:

[0032] ①: 150D / 48F DTY high elastic yarn

[0033] ②: 100D / 72F DTY Coolpass

[0034] Weaving method: The loom used is a 34” 24G towel loom with reverse-wrapped computer jacquard weave. The loop arrangement is 10 loops with loops and 3 loops without loops. The pile height is 1.8mm.

[0035] The blank consists of:

[0036] ①: 150D / 48F DTY high elastic yarn, for terry loops, yarn length 16.2cm / 50N, yarn feed ratio 46%;

[0037] ②: 100D / 72F DTY Coolpas, used as base yarn, yarn length is 30cm / 50N, yarn consumption ratio is 54%.

[0038] Through processes including weaving, dyeing, softening, napping, combing, shearing, fleece spinning, and setting, a jacquard fleece single-sided fleece with a weight of 220 g / m² is obtained. 2 .

[0039] The fabric thickness was evaluated using ISO 5084 test method, the breathability was tested using GBT 5453 test method, the warmth retention was evaluated using GBT 11048 test method, and the light absorption and heat generation function was evaluated using GTT TM 044 test method. The test results showed that the fabric thickness was 2.5mm, the air permeability was 189mm / s, the warmth retention rate was 31.65%, and the light absorption and heat generation function increased the temperature by 2.3℃.

[0040] This fabric has good breathability and heat retention properties, and good elasticity.

[0041] Comparative Experiment 1:

[0042] The same weaving, dyeing, finishing, and napping processes as in Example 1 were used, the difference being the yarn. The 150D / 48F DTY high-elastic yarn was replaced with ordinary polyester yarn 150D / 48F DTY; the 100D / 72F DTY Coolpass was replaced with ordinary polyester yarn 100D / 72F DTY.

[0043] ①: 150D / 48F DTY, for terry loops, yarn length 16.2cm / 50N, yarn feed ratio 46%;

[0044] ②: 100D / 72F DTY, used as base yarn, yarn length is 30cm / 50N, yarn consumption ratio is 54%.

[0045] Through processes including weaving, dyeing, softening, napping, combing, shearing, fleece spinning, and setting, a jacquard fleece single-sided fleece with a weight of 220 g / m² is obtained. 2 .

[0046] The fabric thickness was evaluated using ISO 5084 test method, the breathability was tested using GBT 5453 test method, the warmth retention was evaluated using GBT 11048 test method, and the light absorption and heat generation function was evaluated using GTT TM 044 test method. The test results showed that the fabric thickness was 2.4 mm, the air permeability was 165 mm / s, the warmth retention was 28.65%, and the light absorption and heat generation function increased the temperature by 1.8℃.

[0047] The fabric has poorer breathability and heat retention than that of Example 1, and its elasticity is also poor.

[0048] The function and effect of this embodiment:

[0049] As can be seen from the above embodiments, using DTY high-elastic yarn and Coolpass as raw materials, a reverse-wrapped computer jacquard knitted fabric is woven. The fabric forms a three-dimensional aesthetic with a strong three-dimensional effect, good wrinkle resistance and breathability, ideal elasticity, and good heat retention and warmth retention performance, thus improving the comfort of wearing.

[0050] As can be seen from the above embodiments, jacquard fleece single-sided fleece is mainly used in autumn and winter sports and leisure. The fabric contains Coolpass, which has the characteristics of being lightweight, breathable and quick-drying, with good moisture wicking performance and elasticity, thus improving the comfort of wearing it.

[0051] As can be seen from the above embodiments, the fleece layer has several perforations, and the inner layer has several breathable parts. The breathable parts penetrate the perforations and protrude from the fleece layer surface. When the fabric is made into clothing and worn, the air inside and outside the fabric can circulate and exchange freely through the breathable cavity, thereby ensuring the breathability of the fabric and improving the comfort of wearing it.

[0052] As can be seen from the above embodiments, the limitations of the loom in the weaving process, which prevent the addition of elastic fibers such as high-elastic yarn, have been overcome, resulting in fabrics that lack stretchability, elongation, and resilience.

[0053] While the foregoing has focused on embodiments, these are merely illustrative and do not limit the invention. Those skilled in the art will understand that various modifications and applications not illustrated above can be made without departing from the essential characteristics of these embodiments. For example, the constituent elements specifically shown in the embodiments can be implemented through modifications. Furthermore, various differences related to such modifications and applications should be interpreted as being included within the scope of the invention as defined in the appended claims.
