Bombax cotton thermal shell fabric and its manufacturing method

Abstract

The invention discloses a kapok warm face material. The fiber ingredients and the ratio are: natural kapok fiber 10-100%, cotton or other fiber 0-90%, urethane elastic fiber and other elastic fiber 0-50%. The invention also discloses the manufacture method including the following steps: selecting the fiber ingredients; spinning after mixing the raw material; weaving on the knitting great circle machine; dyeing and after processing. The advantage of the invention is good warm effect, soft tactility and comfort.

Description

technical field [0001] The invention relates to a thermal insulation fabric and a manufacturing method thereof, in particular to a manufacturing method of a kapok thermal insulation fabric. Background technique [0002] Kapok fiber is the fruit fiber of several plants in the kapok family of the order Mallow. It is a single-cell fiber, which is attached to the inner wall of the kapok capsule shell, and is formed by the growth and development of the inner wall cells. Generally, the length is about 8~32mm, and the linear density is 0.5~0.8dtex. The linear density of commonly used cotton, wool, silk and hemp fibers is above 1.0dtex, so kapok fiber is a natural microfiber. The outer surface of kapok fiber is smooth and does not show inflection. The cross section is circular or oval. The longitudinal appearance is a cylindrical shape with a slightly thick middle section, a thin tip, a blunt root end and closed ends. The cells are filled with air, and the hollowness of the fiber ...

Problems solved by technology

One is to use synthetic fibers to keep warm, including hollow polyester, acrylic, polyester elastic yarn, etc. Some are processed into knitted fabric structures, some are composite fabrics with flocks sandwiched in the middle of two-layer knitted fabrics, and some directly sandwich elastic yarn on the second layer. In the middle of knitted fabrics, the still air inside or between fibers is used to keep warm. Due to the limited amount of still air, the fabric has to be made very thick, which affects comfort and appearance.

Another large category of thermal underwear is traditional knitted fabrics made of pure cotton or blended with other fibers, which have good comfort, but the amount of still air between and within the fibers is relatively small, and the warmth retention is poor.
