Description

Technical Field

[0001] The invention belongs to the technical field of knitted fabrics, and specifically refers to a production process of a warm and breathable knitted fabric. Background Art

[0002] With the development of society and the advancement of technology, my country's fabric industry has developed rapidly, and a variety of fabric types have emerged. As people have higher and higher requirements for the comfort of life, they have more refined requirements for fabrics for daily use, especially for knitted fabrics. As a popular trend in recent years, knitted fabrics are loved by consumers because of their soft texture, moisture absorption and breathability, excellent elasticity and extensibility. Knitted clothing does not feel restrained when worn on the body, fits the body closely, and has a good slimming effect. Printed knitted fabrics have a variety of colors and patterns and are widely used in various clothing fabrics. The coil structure of knitted fabrics can retain more air, so it has good breathability, moisture absorption and warmth retention, and is comfortable to wear. This feature is the condition that makes it a functional and comfortable fabric, but attention should be paid to ventilation, keeping dry, and preventing mildew during the circulation or storage of finished products.

[0003] At present, the knitted fabrics on the market have poor air permeability, and those with good air permeability cannot keep warm. The fabrics on the market cannot better meet the needs of knitted fabrics. The Chinese invention patent with patent number CN201410052915.7 discloses a moisture-absorbing, heat-generating, quick-drying, moisturizing and warm fabric and its preparation method, but the fabric structure of the patent is relatively complex, divided into three layers: outer layer, middle layer and inner layer, and the fabric is relatively thick. The product does not meet people's requirements for light, thin and warm clothing for warm fabrics. People are in urgent need of a knitted fabric that is breathable, warm and comfortable.

The present invention uses heat-generating fibers, which have intrinsic flame retardant, antibacterial, heat-generating and warm-keeping properties. The formula can give the fabric permanent antibacterial properties without affecting the overall performance of the fabric, and the fabric is warm and heat-generating. The honeycomb modified polyester fiber used in the present invention can improve the dyeing properties of the fiber. The modified fiber structure becomes loose, the crystallinity is reduced, the dye solution can easily enter the interior of the fiber, and a better dyeing effect can be obtained. The knitted fabric made by the present invention is warm and comfortable, and has the characteristics of moisture absorption, quick drying, and breathability.

[0008] Further, the polyester fiber is a honeycomb-modified polyester fiber.

[0009] Further, the acrylic fiber has a fineness of 0.5-1.5 dtex and a length of 30-45 mm.

[0010] Further, the viscose fiber is an acrylic fiber with a fineness of 0.8-1.7 dtex and a length of 35-40 mm.
