Description

Technical Field

[0001] The invention relates to the technical field of textile fabrics, and in particular provides a method for preparing a black and white checkered jacquard fabric. Background Art

[0002] Black and white checkered fabric is a kind of fabric with a checkered pattern on the surface. In recent years, this kind of fabric has been widely used in clothing and home design. Moreover, with the renewal of people's consumption concepts and the increase in enthusiasm for returning to nature, the functions of the fabric have become more diversified and the combinations have become more diversified. The style has also become trendy and the texture has become softer.

[0003] Currently, the black and white plaid patterns available on the market are produced by the post-processing process - printing. However, as time goes by, this printed pattern on the clothing fabric will become less and less clear, the color will become darker and the glossiness will be poor, and it will easily shed as people wash and wear it more and more.

[0004] Secondly, the plaid fabrics processed by existing jacquard equipment have a small pattern cycle, a single combination and a poor three-dimensional effect. They cannot be used in textiles such as clothing fabrics and bedding, and thus cannot meet actual application needs, causing certain losses. Summary of the Invention

[0005] The purpose of the invention is to provide a preparation method of a black and white checkered jacquard fabric, which solves the problems of unclear patterns, dark colors, easy shedding of existing checkered fabrics, small pattern cycles, single combinations and lack of three-dimensional effect.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] The present invention provides a method for preparing a black and white checkered jacquard fabric. The black and white checkered jacquard fabric comprises a velvet yarn structure and a base yarn structure. The velvet yarn structure accounts for less than 80% by mass of the fabric, and the rest is the base yarn structure. The velvet yarn structure uses 150D semi-gloss flat yarn and 150D cationic yarn as the velvet yarn, and the base yarn structure uses 75D filament as the base yarn raw material.

[0008] The preparation method comprises the following steps:

[0009] S1 raw material selection: 150D semi-gloss flat yarn and 150D cationic yarn were selected as the velvet yarn, and 75D filament yarn was selected as the raw material for the base yarn.

[0010] S2 warping, warping the raw materials in S1 through a warping machine;

[0011] S3 weaving, the raw materials after warping in S2 are fed to the warp knitting machine according to the weaving process to obtain the grey fabric and cut it into pieces;

[0012] The yarn laying numbers of each combing bar in the weaving process are:

[0158] In order to further illustrate the beneficial technical effects of each embodiment, the colored silk fiber fabrics in Examples 1-4 and Comparative Examples 1-9 were tested for pattern circulation (visual inspection) and hair loss test (hair adhesion). The full score is 5 levels, and the higher the level, the better the pattern circulation (visual inspection) and hair adhesion. The results are listed in Table 1.

[0159] The black and white checkered jacquard fabrics prepared in Examples 1-4 and Comparative Examples 1-9 were subjected to relevant performance tests according to the current corresponding national standards of my country. The test results are shown in Table 1.

[0160]

[0161]

[0162] As can be seen from Table 1, the comparative examples 1-4 and 1-3 of the present invention all use 6 combs and adopt the same weaving process. The raw materials of the velvet tissue in the comparative examples 1-3 are different from those in the examples 1-4. The processed fabric pattern cycles are worse than those in the examples 1-4. The patterns are not clear and the visual effect is poor, which cannot meet the actual use requirements (reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 );

[0163] Furthermore, in the present invention, when GB1 and GB6 in the weaving process are changed, the hairiness adhesion of the black and white checkered fabric processed is poorer than that of Examples 1-4, the hair loss test is poor, and it is easy to tear;

[0164] Furthermore, in the comparative examples 1-4 of the present invention and comparative examples 5 and 8, when any of GB2 and GB5 in the weaving process is changed, when the double needle bed warp knitting machine uses this weaving process to process woven fabrics, it is difficult to operate. According to the principle of the wool height of the warp knitting machine, GB2 and GB5 are in the weaving chain, and the double needle bed warp knitting machine is easy to stop during the weaving process and cannot produce normally;

[0165] Furthermore, the present invention compares Examples 1-4 with Comparative Examples 6 and 7. When any of GB3 and GB4 in the weaving process is changed, the visual effect of the processed fabric is worse than that of Examples 1-4. The pattern cycle pattern is not clear and the hair height is inconsistent, resulting in a poor three-dimensional effect of the black and white checkered pattern, which cannot meet the actual use requirements (reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 ).

[0166] In summary: through the selection of raw materials and the improvement of weaving technology, the pattern cycle (visual inspection) and hair loss test of the processed black and white checkered fabric are better, and the pattern cycle of the processed fabric is increased, the three-dimensional sense is stronger, and the texture is clear, which meets the application needs of the actual market, so that the fabric can be effectively used in textiles such as clothing fabrics and bedding.

[0167] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
