Description

High-density weft-knitted cationic terry knitted fabric

Technical Field

The utility model relates to a high-density weft knitting terry knitted fabric, in particular to a high-density weft knitting positive ion terry knitted fabric.

Background

The superfine fiber technology, i.e. the differential fiber or the chemical synthetic fiber technology, mainly uses two different chemical substances to enable the fineness of the fiber to be less than 1.0 fine denier (the standard of the finest fineness of single-component fiber) through a professional textile technology, so the superfine fiber is called as the superfine fiber.

Circular knitting machines, known as circular weft knitting machines (or circular knitting machines). The circular knitting machine has the advantages of high loop forming system (called yarn feeding path number or loop forming path number in enterprises for short) quantity, high rotating speed, high yield, quick pattern change, good quality of knitted fabrics, few working procedures and strong product adaptability, so the circular knitting machine is developed quickly.

At present, the high-density weft-knitted terry fabric is produced by the circular knitting machine by adopting common superfine fibers, such as polyester-nylon composite fiber yarns. The terry knitted fabric has: the antibacterial, skin-friendly, super-absorbent and scratch-free wiping film has the excellent characteristics of antibiosis, skin-friendliness, super-absorbency and no trace in wiping, and is widely applied to: 1. wiping industrial precision instruments and equipment; 2. cleaning and beautifying the inside and outside of the automobile; 3. wiping and cleaning door and window glass, furniture, kitchen and bathroom supplies and the like. The double-color effect of the terry knitted fabric can only be woven by a yarn-dyed process, and the weaving cost is relatively high.

In addition, in the high-density weft-knitted loop fabric of the conventional design, the basic structure adopts the design of single yarn looping in the width direction of the fabric, so that the condition that yarns are easily dropped after the loop cutting treatment of the loop fabric is easily caused.

The cation yarn belongs to a modified superfine fiber, such as cation polyester yarn or cation nylon yarn or cation polyester-nylon composite fiber yarn, and the like, cation active agent is added to modify the cation active agent before spinning or in the spinning process (for example, sulfonate is usually used as a modifier to modify modified polyester which can be dyed by cation dye), the yarn prepared by the cation active agent is called cation yarn, and the cation yarn is high temperature resistant and needs to be dyed by cation dye.
