The 35% Lyocell fibers 30% polyamide fibre 20% large tmaterial of cotton 15% spun silk one side and preparation method
Technical field
The present invention relates to a kind of preparation method of fabric, relate in particular to the preparation method of the large tmaterial of a kind of one side.
Background technology
Lyocell fibers has high dry, wet brute force, has higher swellability, good spinnability.
Polyamide fibre have hygroscopicity and dyeability all, polyamide fibre better, alkaline-resisting and not acidproof than terylene have thermal finalization characteristic, can keepThe flexural deformation forming while firmly heating.
Cotton feature is that moisture absorption is strong---cotton fiber is porous material, and interior molecules is arranged very irregular, and in moleculeContain a large amount of hydrophilic-structures. Warmth retention property----cotton fiber is hot non-conductor, and the inner chamber of cotton fiber has been full of immobilisingAir, comfortable and easy to wear---can not produce static, good air permeability, anti-sensitivity, easily cleans.
It is high that spun silk has number, and gloss profit is beautiful, feel is soft, be suitable for manufacturing light and soft senior fabric.
Summary of the invention
The object of this invention is to provide a kind of 35% cotton 15% spun silk one side of Lyocell fibers 30% polyamide fibre 20% large tmaterialPreparation method, adopts the large tmaterial of one side prepared of the method, possesses the characteristic of Lyocell fibers, polyamide fibre, cotton and spun silk simultaneously,Have that moisture absorption is strong, swellability, gas permeability, warmth retention property compared with high, gloss profit is beautiful, feel is soft, durability, alkaline-resisting and not acidproof,There is thermal finalization characteristic, the flexural deformation forming can maintain heating time.
In order to realize above-mentioned object, the present invention has adopted following technical scheme:
The preparation method of the large tmaterial of the 35% cotton 15% spun silk one side of Lyocell fibers 30% polyamide fibre 20%, the method comprises followingStep:
1) raw material is prepared: 120N/2 days cotton 20/ thin,tough silk 15 dyed yarns of silk 35/, 20D/2 polyamide fibre 30;
2) weave: install the special shuttle triangle that adds additional at 34 cun of 30G single-side jacquards, An48 road row's pin is compiled in computer softwareVolume design colored type, by computerized version figure and color matching, dyed yarn is accessed accordingly into yarn way, wherein 20D polyamide fibre is done to add shuttle and is madeWith;
3) open-width; Adopt horizontal scutcher, expander linear velocity < 60m/min;
4) clear water shaping and drying;
5) mercerization: dry body cloth open-width joint is directly gone up machine and done gently alkali mercerizedly, first adds Fe by 100g/L in mercerising process3+Chelated dispersants improves water quality, NaOH concentration 220-270g/L, and 0.2% silkete penetrating agent, by 25m/min normal temperature mercerising, alkali lye rollsAfter washing, in the time of open washing, add 90g/L glacial acetic acid and carry out acid-base neutralization, PH Zhi≤7, and play tint retention;
6) secondary sizing: secondary sizing adds the fluffy softening agent of 45 ~ 65g/L, ice-cold finishing agent 45 ~ 65g/L, smooth silicone oil110 ~ 160g/L, 140 ~ 170 DEG C of temperature, overfeeding 25m/min;
7) rubber blanket preshrunk: rubber blanket temperature should be controlled at 45 ~ 70 DEG C, and the speed of a motor vehicle is at 30 ~ 35m/min;
8) decatizing and preshrinking process: fabric after mercerising and sizing is entered to continuous pressure decator and carry out decatizing, steam pressureMore than 6Pa, 20m/min, after decatizing material by steam-shrinkage machine and woollen blanket preshrinking machine to fabric laterally, longitudinal washing shrinkage, knitThing flower type, effective gate width are done processing adjustment;
9) steam-shrinkage: mechanical speed, 15-30m/min, saturated vapor 3-3.5Bar, compressed air 5Bar, to fabricLaterally, longitudinal washing shrinkage, patterns of fabric, effective gate width are done processing adjustment.
Another object of the present invention is to provide the large tmaterial of one side that adopts above-mentioned method to prepare.
The present invention is owing to having adopted above-mentioned technical scheme, and the large tmaterial of one side that legal system is standby possesses lyocell fibre simultaneouslyThe characteristic of dimension, polyamide fibre, cotton and spun silk, have moisture absorption by force, beautiful, the feel of higher swellability, gas permeability, warmth retention property, gloss profitSoft, durability, alkaline-resisting and not acidproof, have thermal finalization characteristic, the flexural deformation forming can maintain heating time.
Detailed description of the invention
The preparation method of the large tmaterial of the 35% cotton 15% spun silk one side of Lyocell fibers 30% polyamide fibre 20%, the method comprises followingStep:
1) raw material is prepared: 120N/2 days cotton 20/ thin,tough silk 15 dyed yarns of silk 35/, 20D/2 polyamide fibre 30;
2) weave: install the special shuttle triangle that adds additional at 34 cun of 30G single-side jacquards, An48 road row's pin is compiled in computer softwareVolume design colored type, by computerized version figure and color matching, dyed yarn is accessed accordingly into yarn way, wherein 20D polyamide fibre is done to add shuttle and is madeWith;
3) open-width; Adopt horizontal scutcher, expander linear velocity < 60m/min;
4) clear water shaping and drying;
5) mercerization: dry body cloth open-width joint is directly gone up machine and done gently alkali mercerizedly, first adds Fe by 100g/L in mercerising process3+Chelated dispersants improves water quality, NaOH concentration 250g/L, and 0.2% silkete penetrating agent, by 25m/min normal temperature mercerising, after alkali lye rolls and washesIn the time of open washing, add 90g/L glacial acetic acid and carry out acid-base neutralization, PH Zhi≤7, and play tint retention;
6) secondary sizing: secondary sizing adds the fluffy softening agent of 60g/L, ice-cold finishing agent 60g/L, smooth silicone oil 140g/L,150 DEG C of temperature, overfeeding 25m/min;
7) rubber blanket preshrunk: rubber blanket temperature should be controlled at 60 DEG C, and the speed of a motor vehicle is at 33m/min;
8) decatizing and preshrinking process: fabric after mercerising and sizing is entered to continuous pressure decator and carry out decatizing, steam pressureMore than 6Pa, 20m/min, after decatizing material by steam-shrinkage machine and woollen blanket preshrinking machine to fabric laterally, longitudinal washing shrinkage, knitThing flower type, effective gate width are done processing adjustment;
9) steam-shrinkage: mechanical speed 25m/min, saturated vapor 3.3Bar, compressed air 5Bar, to fabric laterally,Longitudinally washing shrinkage, patterns of fabric, effective gate width are done processing adjustment.
One side tmaterial prepared by above-mentioned method project is after testing as shown in the table. Examination criteria GB/T22849-2009, GB18401-2003 " B " class.
