Problems solved by technology

[0003] With the improvement of people's living standards, people's requirements for knitted fabrics are getting higher and higher. When wearing pure cotton knitted fabrics, when the human body sweats a lot, the pure cotton knitted fabrics will absorb a lot of sweat and become wet. It becomes heavier, the speed of moisture conduction and dehumidification slows down, and sweat remains on the clothing and skin, which is prone to peculiar smell and even breeds bacteria, which will affect the health of the body
In addition, knitted fabrics also have deficiencies and defects in anti-wrinkle performance. After wearing for a long time, the fabric cannot return to smoothness.
Generally, for the wrinkle resistance of knitted fabrics, it is often treated by dipping anti-wrinkle and anti-shrinkage resin. After treatment, the anti-wrinkle performance of knitted fabrics is improved, but the treatment with antibacterial and anti-wrinkle resins will easily cause the strength of knitted fabrics to decrease and yellowing

Abstract

The invention discloses an antibacterial and crease-resistant knitted fabric and a preparation method thereof. The antibacterial and crease-resistant knitted fabric comprises a fabric base layer, a crease-resistant layer and an antibacterial layer; one side of the fabric base layer is connected with the crease-resistant layer through a knitted coil structure; the crease-resistant layer and the antibacterial layer are connected through a knitted coil; the fabric base layer is formed by weaving warm-keeping breathable composite yarns; the crease-resistant layer is made of elastic crease-resistant covering yarns; and the antibacterial layer is prepared by blending antibacterial functional fibers and antibacterial polyvinyl alcohol fibers according to a ratio of (1.8-2.3): (2-2.5) into yarns. The antibacterial and crease-resistant knitted fabric prepared by the invention has remarkable antibacterial and crease-resistant properties, good washing resistance and durability and excellent moisture absorption and air permeability, and can keep skin dry and prevent sweat from staying on the fabric and breeding bacteria when a human body sweats.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to an antibacterial and anti-wrinkle knitted fabric and a preparation method thereof. Background technique [0002] Knitted fabrics are fabrics made by bending yarns into loops with knitting needles and interlocking them. The difference between knitted fabrics and woven fabrics is the shape of the yarn in the fabric. Knitting is divided into weft knitting and warp knitting. Weft knitting is to feed one or several yarns from the weft direction to the working needle of the knitting machine, so that the yarns are sequentially bent into loops, and are strung together to form weft knitting. things. Warp knitting is composed of one or several groups of parallel yarns arranged on the knitting needles and woven along the longitudinal direction at the same time. The structure and shape of the warp knitted fabric are more stable. Knitted fabric has the characteristics of soft text...
