Problems solved by technology

[0003] Aiming at the addition of spandex in the existing elastic knitted fabric, the spandex is easy to age after repeated stretching, resulting in a great loss of fabric elasticity, and the need to obtain a plush structure through napping treatment, which increases the fabric processing process and processing costs. Problem, the present invention provides an elastic knitted fabric, the elasticity of which will not be lost even after being stretched many times, and has its own fluff structure, which does not require napping treatment. At the same time, the present invention also provides this elastic knitted fabric preparation method

Abstract

The invention provides elastic knitted fabric, and solves problems in existing elastic knitted fabric that spandex is easily aged after multiple times of stretching because the spandex is added, so that fabric elasticity is greatly lost, and a plush structure can be obtained only through napping raising treatment, fabric processing procedures and processing cost are increased. A fabric rough blankof the fabric is formed by interweaving a high F-number yarn and an elastic shrinking yarn, or formed by co-interweaving the high F-number yarn, a common yarn and the elastic shrinking yarn. The highF-number yarn is a yarn of which a D / F range is within 0.5-1.6. The elastic shrinking yarn is a PTT / PET blending filament or a PBT / PET blending filament. The fabric rough blank is shrunk on the surface of an inner layer after dyed so as to form naps. In addition, the invention further provides a preparation method for the fabric.

Description

technical field [0001] The invention relates to the field of knitted fabrics, in particular to an elastic knitted fabric and a preparation method thereof. Background technique [0002] Spandex has excellent elastic properties, so most of the existing elastic knitted fabrics are added with spandex, but because the fabric is often subjected to stretching force during use, spandex is easy to age after repeated stretching, resulting in a great loss of fabric elasticity. Seriously affect the use of fabrics, and if you want to form a plush structure on the surface of the fabric to improve the skin-friendly and thermal performance of the fabric, you also need to dye the fabric, set the shape and then perform napping treatment, which increases the fabric processing and processing costs. Contents of the invention [0003] Aiming at the addition of spandex in the existing elastic knitted fabric, the spandex is easy to age after repeated stretching, resulting in a great loss of fabri...
