Novel anti-pilling sandwich knitted fabric and production process thereof

Abstract

The invention discloses a novel anti-pilling sandwich knitted fabric and a production process thereof. The novel anti-pilling sandwich knitted fabric comprises an inner layer, a middle layer and an outer layer; the inner layer and the outer layer are formed by interweaving cotton yarns and modified spandex; and the middle layer adopts temperature-sensing deformation composite yarns as connecting lines. The production process comprises the following steps of (1) weaving; (2) pre-setting; (3) dyeing; (4) dehydrating and drying; and (5) setting and finishing. The length of the three layers of coils is redesigned, and the low-temperature spandex is added into the cotton yarns of the outer layer and the inner layer, so that the fabric is compact and rich in elasticity; meanwhile, the inner layer and the outer layer are connected through the temperature-sensing deformation composite yarns, and a 180-DEG C pre-setting process is matched, so that the porous filaments are adhered to form the single-hole filaments, and the phenomena of pilling, snagging and unstable structure when the fabric is worn are effectively solved; and the knitted fabric processed by the process has more excellent three-dimensional stiff and smooth feeling, heat-insulating and warm-keeping wearability and soft touch like silk, the after-finishing operation procedure is reduced, and the cost and energy consumption are reduced.

Description

technical field [0001] The invention belongs to the technical field of knitted fabrics, and in particular relates to a novel anti-pilling sandwich knitted fabric and a production process thereof. Background technique [0002] With the gradual improvement of people's requirements for the comfort of clothing fabrics, knitted fabrics have been loved by more and more people in recent years, and the unique fluffy feel and thermal performance of "sandwich" fabrics have conquered consumers. The "sandwich" fabric has a multi-layer three-dimensional structure that can effectively lock the air layer for the purpose of heat storage. At the same time, it has a special appearance and style, with a soft and comfortable fit, which is far more attractive to young consumers than bloated traditional cotton clothing. [0003] The conventional "sandwich" fabrics currently on the market are mostly polyester, which lacks skin-friendliness and comfort. Moreover, the "sandwich" with ordinary polye...

[0003] The conventional "sandwich" fabrics currently on the market are mostly polyester, which lacks skin-friendliness and comfort

Moreover, the "sandwich" with ordinary polyester as the connecting line in the middle layer is very prone to snagging and pilling during wearing. The conventional improvement of pilling and snagging is only achieved by encrypting the outer and inner layers and covering polyester filaments. However, there is still a risk of pilling and snagging in practical applications

However, the use of single-hole nylon yarn can only be used as yarn-dyed fabrics, and the defect rate is relatively high, while the use of cotton instead will feel soft, easy to deform, and does not have a three-dimensional crispness
