Warm-keeping sweater containing modified polyester fiber and processing technique thereof

Abstract

The invention discloses a warm-keeping sweater containing modified polyester fiber, which is woven from blended yarn. The blended yarn comprises modified polyester fiber, modal fiber and viscose fiber which are doubled and twisted into the blended yarn at 320t/m. The processing of the sweater comprises the steps of: dyeing: heating dyes in a dye bath to 86-88 DEG C at the temperature rising rate of 0.6DEG C/min, dyeing and then fully rinsing the dyed blended yarn; weaving the dyed blended yarn into woven pieces of the sweater on a weaving machine, carrying out looping, flat sewing, hand sewing, washing and drying, wherein a rolling type dryer is used for drying in the drying process; and setting a finished sweater product by using a setting machine after the drying treatment, wherein the temperature of the setting machine is controlled to be between 135 DEG C and 138 DEG C in the setting process,. Due to adoption of the blending and the processing technique of the sweater, the sweater clothes with fine and soft fiber and good warm-keeping effect can be weaved.

Description

technical field [0001] The invention relates to a sweater garment and its processing technology, in particular to a warm sweater containing modified polyester fiber and its processing technology. Background technique [0002] Soft feel and warmth are important indicators of clothing comfort in spring, autumn and winter. The traditional method of keeping warm is usually to control the heat loss caused by heat conduction, convection, and radiation, that is, to use thick fabrics or add cotton wool to keep warm. Metallic coated fabrics are also used, the aforementioned materials do not have soft characteristics. However, modern people have higher and higher requirements for the comfort, functionality and aesthetics of clothing. Traditional thermal insulation materials are generally bulky, inconvenient for movement and lack of aesthetic feeling; for people working in extremely low temperature environments, passive Warmth does not do a good job of meeting the functional requireme...
