Suzhou Dobby Jacquard–Using new raw materials to develop weft knitted products
Weft knitted products are developing towards the aspects of being light, elastic, comfortable, functional, smooth, green and environmentally friendly, integrally knitted and seamless underwear, industrial knitted fabrics, etc. The continuous emergence and application of new fiber materials provide more choices for the design and development of weft knitted products. The article summarizes the current developments at home and abroad in the use of new natural fiber and chemical fiber raw materials to develop weft-knitted apparel and industrial products.
Weft knitted products include three categories: clothing, decorative and industrial use. At present, clothing products account for more than 80%, but the proportion of the latter two types of products is gradually increasing. The development of weft knitted products involves four aspects: the selection and combination of raw materials, fabric structure and pattern design and knitting technology, finishing technology, and the design and production of final products. Among them, the selection and combination of raw materials and the finishing technology have Product performance, style, functionality and quality play an increasingly important role. In recent years. The continuous emergence and application of new fiber materials. Modification and deformation of existing textile raw materials. And the increasing progress of spinning technology. Provides more choices for the design and development of weft knitted products. This article will review some of the current developments at home and abroad in the development of new weft-knitted products using new raw materials.
1 The development trend of weaving knitted products
At present, weir weave knitted products, especially the use of fabrics, are developing in the following aspects.
1.1 Light and Light
In order to meet the requirements of people’s lives and working environment and the requirements of wearing comfort, more and more knitted fabrics use thinner yarns and high -machine knitting machines to knit. For example, the high-end circular knitting machine has reached E44, and the flat knitting machine has reached E18. The weight of light and thin fabrics is only a few dozen grams per square meter.
1.2 Elasticity
In addition to some swimwear and professional sportswear, such as high spandex content and large elasticity, many daily wear clothing adds 2 % to 10 % spandex, so that the fabric has more than the more than the fabrics. The small elasticity is mainly to improve the shape retention of fabrics and clothing and make it easy to care for after washing.
1.3 Comfort
This involves the hot and wet transmission performance of the fabric and clothing, the touch of the skin, and the pressure of the human body. The heat and moisture transfer performance can be improved by using functional fibers such as moisture conduction and warmth retention, as well as the rational design of yarns and knitted fabric structures: through pre-processing of yarns and post-finishing of fabrics, the uncomfortable touch to the skin can be improved and eliminated. , such as the itching sensation of ramie fabrics and wool fabrics; through the selection of raw materials, the optimized design of fabric structure and clothing styles, the pressure of clothing on the human body can be maintained at a reasonable and comfortable level.
