Yarn-dyed fabrics have been widely used in society today. Among the factors affecting yarn-dyed fabrics, in addition to color matching, the different fabric structures have a great influence on the appearance of yarn-dyed fabrics, and yarn-dyed jacquard has become a highlight. In recent years, with the rapid development of textile patterns and colors, its organizational structure has long been freed from being single, flat, and dull, and has developed in the direction of being bright, lively, and changeable. And with its unique advantages such as soft and delicate texture, strong practicality, realistic patterns, strong three-dimensional sense, plump and pleasing appearance, and high color fastness, it has soared in market sales.
Yarn-dyed jacquard fabrics are weaving patterns directly on high-quality grey fabrics by weaving factories, and the demand for raw cotton is extremely high. The yarn is first dyed and then woven on a jacquard loom, and finally processed. Therefore, yarn-dyed jacquard fabrics have more than two colors, the fabric color is rich, not monotonous, the pattern has a strong three-dimensional sense, and the level is higher. It can be divided into shuttle weaving, warp knitting jacquard and weft knitting jacquard.
Weft knitted fabrics have excellent elasticity when pulled horizontally and vertically, while warp knitted and woven jacquard fabrics have no elasticity when pulled horizontally and vertically. The warp and weft yarns interweave and rise and fall to form different patterns. The pattern of large jacquard fabrics is large and delicate, with distinct color layers and a strong three-dimensional sense, while the pattern of small jacquard fabrics is relatively simple and single.
The process of color weaving is complex and is a very professional system engineering. Colored fabrics are woven with colored spun yarn, dyed yarn, fancy yarn and bleached yarn, and the fabric organization is changed. In order to obtain the final ideal effect of color fabrics, a series of color fabric finishing processes must be carried out to fully reflect the appearance style of color fabrics and ensure their inherent quality.
The finishing of color fabrics should be based on their different characteristics and select different process combinations, but there are only two most important ones:
1. Singeing: Singeing is one of the most commonly used means of textile post-processing. The main purpose is to remove weaving defects on the surface of color-woven fabrics. After singeing, the elastic color-woven fabric surface is clean and free of weaving defects. However, due to the large number of fancy structures of colored fabrics, special attention should be paid during the singeing process. When different products pass through the burner quickly at high temperature, different burner directions should be selected for different fabrics for singeing.
2. Desizing: Desizing is mainly to remove most of the sizing agent, so that the original line outline is clear and the warp and weft density of the fabric reaches the specified value. On the one hand, the warp and weft density depends on preshrinkage, and on the other hand, desizing is also a factor in controlling the warp and weft density and width. In addition, desizing is conducive to the full shrinkage of the fabric and is more conducive to the grasp of shaping. Desizing removes oil stains stained during the warp weaving process, various impurities on the sizing agent and the weft viscose, so that the internal stress of the fabric is completely released and the elasticity is fully restored.
The biggest advantage of jacquard cloth is that it has pure and natural colors, smooth lines, unique style, and noble temperament in simplicity. It is very easy to match various furniture, which is unmatched by printed cloth. Jacquard fabrics have a history of thousands of years. It is the product of the fusion of science and art in the development of textile technology. my country's jacquard fabrics have profound Chinese culture and national characteristics.
Jacquard yarn-dyed fabric products have high technical added value, and their weaving effect, pattern style and fabric appearance are not comparable to traditional products. Jacquard fabrics have rich patterns, colors and three-dimensional sense. Their patterns are reflected by the combination of organization and warp and weft, while plain fabrics completely rely on the changes in the fabric organization to show the layered effect of the pattern. The pattern of jacquard fabrics is reflected by the combination of fabric organization and warp and weft. Therefore, the design of the product appearance effect is an extremely important issue. The conditions for forming the appearance pattern are the arrangement of color warp, color weft and fabric organization. Changing any of the constituent factors will form a different appearance effect.
The fabric style composed of various organizations and colors makes the color fabric have a strong visual effect. The jacquard produced by the warp and weft bidirectional makes the pattern rich in changes, the style is changeable, the pattern is numerous, the appearance is plump and pleasing, and the added value of the fabric is high, which is deeply loved and favored by consumers. In particular, the newly developed large-pattern yarn-dyed curtain fabric products have a simple and elegant appearance and a very strong decorative effect, which is very in line with the needs of people today.
