Why are knitted fabrics more elastic and breathable than woven fabrics? Please tell me.

One. Using the elasticity of knitted fabric

Knitted fabrics have good elasticity, and seams, folds and splices designed for modeling can be minimized in pattern design. Secondly, knitted fabrics are generally not suitable for modeling by pushing back and ironing, but use the elasticity of the fabric itself or properly use wrinkle techniques to fit the human body curve. Then the elasticity of fabric becomes an important basis for model design and production.

The pattern of woven clothing is generally larger than the area needed to wrap the human body, that is, it has a certain degree of looseness relative to the human body; For knitted clothing, it depends on the fabric structure. If the fabric with particularly high elasticity is designed (related to yarn and weave structure), it will not leave a loose feeling, and its pattern size can be the same as that of people, and the elastic coefficient can also be reduced.

Secondly, by using the curling characteristics of knitted fabrics

The curling of knitted fabric is caused by the disappearance of internal stress in the fabric edge loop. Curlability is the shortcoming of knitted fabrics. It will cause uneven seams or changes in the size of the garment edge, which will eventually affect the overall modeling effect and size of the garment. However, not all knitted fabrics have hemming, only fabrics with individual structures have hemming, such as weft knitted flat fabrics. For this kind of fabric, the pattern design can be solved by increasing the size for wrapping, setting ribs or wrapping, and embedding adhesive lining on the edge of clothing. In the process of fabric finishing, the curl of some knitted fabrics is eliminated, and the trouble of pattern design is avoided.

It should be pointed out that many designers can turn disadvantages into advantages on the basis of understanding the properties of fabrics, and use the curling property of fabrics to design the neckline and cuffs of models, so that the clothing can obtain a special appearance style, which is refreshing, especially in the weaving of molded clothing, and can also use its curling property to form unique patterns or parting lines.

Third, pay attention to the detachability of knitted fabrics.

Knitted fabric is different from woven fabric in style and characteristics, and its clothing style should not only emphasize the advantages of fabric, but also overcome its disadvantages. Because some knitted fabrics are loose, it should be noted that some knitted fabrics should not be exaggerated too much, and darts and cut lines should not be designed as far as possible, and there should not be too many sewing lines to prevent loose knitting loops from affecting the wearability of clothing. Simple and soft lines should be used to coordinate with the soft and fit style of knitwear. Organic cotton is a kind of natural, high-quality and pollution-free environmental protection cotton. Do not use any pesticides, forward the products produced and processed by raw cotton, and be certified by an independent certification body. Organic cotton mainly uses organic fertilizer, biological and natural farming to control pests and diseases in agricultural production, and chemicals are not allowed; From seeds to agricultural products, cotton produced in a natural and pollution-free way is measured by the safety and quality standards of agricultural products published by various countries or WTO/FAO, and the contents of toxic and harmful substances such as pesticides, heavy metals, nitrates and pests (including microbial parasite eggs) in cotton are controlled within the limits stipulated by the standards; And get certified commodity cotton. The production of organic cotton not only needs the necessary conditions such as light, heat, water and soil for cotton planting, but also has specific requirements for the cleanliness of cultivated soil environment, irrigation water quality and air environment. Xinjiang is the planting base of organic cotton in China, with superior light and heat conditions, long sunshine time, light pests and diseases, many kinds and quantities of natural enemies, rich sources of organic fertilizer, irrigation water from Tianshan meltwater, and pollution-free soil.
