Embodiment Construction

[0019] 1. Raw materials: 65% 1.56dtex×38mm cationic polyester and 35% cotton. It can be treated before spinning. According to the test: it is enough to humidify before packing, but it must be stacked for a certain period of time, generally not less than 24 hours, so that the moisture can penetrate evenly. In addition, the humidity control should be based on the principle of gradually dehumidifying. The blowing process is controlled at about 65%-70%, the combing process is controlled at about 60%-65%, and the eddy current spinning process is controlled at about 50%.

[0020] 2. Spinning process flow: FA002A automatic plucking machine → FA022 multi-compartment blending machine → FA106A cotton opener → FA046A vibrating cotton box feeder → A076F single hand lapping machine → FA224B carding machine → HSD961 drawing frame Machine (one parallel, two parallel)→TD03-600 draw frame (three parallel)→MVS861 vortex spinning machine.

Abstract

The invention discloses a production technology of cationic polyester and cotton blended yarn. The cationic polyester and cotton blended yarn comprises 65% of cationic polyester and 35% of cotton. According to the production technology, through working procedures such as opening and cleaning, cotton carding, drawing, vortex spinning and the like, fiber is spun into the yarn through a blending technology, and the problem that normal fiber is difficult to dye is solved. The cationic polyester and cotton blended yarn has the advantages that the product quality is excellent, the surface is bright and clean, the evenness is provided, and the hairness is low; a product processed from the cationic polyester and cotton blended yarn has abrasion resistance, fuzzing resistance, pilling resistance, uniform cloth surfaces and good moisture absorption, breathability and draping, and can meet the functional requirements of customers for fabric.

Description

technical field [0001] The invention relates to the technical field of blended yarns, in particular to a production process for cationic polyester-cotton blended yarns. Background technique [0002] The chemical name of polyester fiber is polyethylene terephthalate, which is a hydrophobic synthetic fiber and lacks functional groups that can combine with direct dyes, acid dyes, and basic dyes. Although it has lipid groups that can form hydrogen bonds with disperse dyes, polyester has a tight branched chain structure, and dye molecules are not easy to enter the interior of the fiber, resulting in difficult dyeing and monotonous color, which directly affects the development of polyester fabric designs and varieties. Due to the high crystallinity of polyester, there are only small voids in the fiber. When the temperature is low, the thermal movement of molecules changes its position to a small extent. Under humid conditions, polyester fiber does not pass through violently like c...
