Embodiment 1

[0026] Processing Technology of Hygroscopic and Warm Hollow Cotton Woven Fabric

[0027] Step 1, fabric weaving: 16 warp yarns, including a 50D water-soluble filament, and the rest are cotton fibers, 12 weft yarns, including a 75D water-soluble filament, and the rest are cotton fibers, and the spinning method is compact spinning; The weaving process is the same as ordinary cotton woven fabric, the density is 108*56; among them, the water-soluble filament is polyvinyl alcohol fiber;

[0028] Step 2. Singeing: Use a gas singeing machine to make the fabric pass through two singeing burners, one positive and one reverse, in sequence, and the singeing grade is above grade 4;

[0029] Step 3, cold stacking: Padding the fabric with caustic soda, desizing enzyme and refining agent, rolling and stacking for 24 hours; among them, the amount of caustic soda is controlled at 100g / L, the concentration of refining agent is controlled at 5g / L, and the temperature is controlled at 102±2 ℃, t...

Abstract

The invention discloses a processing technology of a moisture-absorbing and heat-retaining hollow cotton shuttle fabric: 1. Weaving of the fabric: the warp yarn contains water-soluble filaments, and the weft yarn contains water-soluble filaments; 2. singeing; 3. cold stacking: padding the fabric with caustic soda , desizing enzyme and refining agent, coiled and stacked for 24 hours; among them, the amount of caustic soda is controlled at 100g / L, the temperature is controlled at 102±2°C, and the fabric liquid rate is 100%; 4. Scouring and bleaching: used for fabrics after cold stacking The combined descouring and bleaching machine is used for boiling and bleaching, followed by water washing, steam scouring, water washing, steam bleaching, water washing, and drying; among them, the amount of scouring alkali is controlled at 80g / L; 5. Mercerizing: the concentration of mercerizing lye is controlled at 200g / L; 6. Dyeing; 7. Finished product setting: use double fatty amide-based softening agent; 8. Pre-shrinkage; 9. Air washing. While ensuring the same appearance style, the product of the invention can obtain lower grammage and more fluffy and soft hand feeling, and has excellent moisture absorption and warmth retention.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a moisture-absorbing and warm-keeping hollow cotton woven fabric and a processing technology thereof. Background technique [0002] Since the thermal conductivity of still air is small, the more still air contained in the fabric, the better its warmth retention effect. The technology of using polyester to make hollow fibers has been widely used, but polyester has poor wearing comfort, so it is necessary to study the textile dyeing and finishing technology of natural fiber hollow yarns. In 2005, Ma Huiying of Tianjin University of Technology and others used vinylon as core-spun yarn, and produced cotton hollow yarn after spinning. In 2008, Zhao Jingran, Zhang Guangxu and others from Donghua University produced cotton hollow yarn and porous yarn, and discussed the thermal insulation effect comparison of cotton hollow yarn, cotton porous yarn and conventional yarn in knitted fabri...
