The 35% Lyocell fibers 30% polyamide fibre 20% large FIGURED CLOTH of cotton 15% spun silk one side and preparation method
Technical field
The present invention relates to a kind of preparation method of fabric, particularly relate to the preparation method of the large FIGURED CLOTH of a kind of one side.
Background technology
Lyocell fibers has high dry, wet brute force, has higher swellability, good spinnability.
Polyamide fibre has that hygroscopicity and dyeability are all good, alkaline-resisting than terylene and not acidproof, polyamide fibre has HEAT SETTING characteristic, the flexural deformation formed when can maintain heating.
Cotton feature is that moisture absorption is strong---cotton fiber is porous material, interior molecules arrangement very irregular, and containing a large amount of hydrophilic-structures in molecule.Warmth retention property----cotton fiber is the non-conductor of heat, and the inner chamber of cotton fiber is filled with immobilising air, comfortable and easy to wear---can not produce electrostatic, 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 the light and soft fine fabrics of manufacture.
Summary of the invention
The object of this invention is to provide the preparation method of the large FIGURED CLOTH of the cotton 15% spun silk one side of a kind of 35% Lyocell fibers 30% polyamide fibre 20%, adopt the large FIGURED CLOTH of one side prepared by the method, possesses the characteristic of Lyocell fibers, polyamide fibre, cotton and spun silk simultaneously, have moisture absorption by force, higher swellability, gas permeability, warmth retention property, gloss profit is beautiful, feel is soft, durability, alkaline-resisting and not acidproof, have HEAT SETTING characteristic, the flexural deformation formed when can maintain heating.
In order to realize above-mentioned object, present invention employs following technical scheme:
The preparation method of the large FIGURED CLOTH of the cotton 15% spun silk one side of 35% Lyocell fibers 30% polyamide fibre 20%, the method comprises the following steps:
1) raw material prepares: 120N/2 days cotton 20/ thin,tough silk 15 dyed yarns of silk 35/, 20D/2 polyamide fibre 30;
2) weave: install additional at 34 cun of 30G single-side jacquards and specially add shuttle triangle, by 48 tunnels row's pins, design flower pattern, access into yarn way by computerized version figure and color matching accordingly by dyed yarn at computer software inediting, wherein 20D polyamide fibre is done to add shuttle and is used;
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 mercerized, first adds Fe by 100g/L in mercerising process
3+chelated dispersants improves water quality, NaOH concentration 220-270g/L, 0.2% silkete penetrating agent, by 25m/min normal temperature mercerising, adds 90g/L glacial acetic acid carry out acid-base neutralization, PH Zhi≤7 after alkali lye rolls and washes when open washing, and plays tint retention;
6) secondary sizing: secondary sizing adds the fluffy softener of 45 ~ 65g/L, ice-cold finishing agent 45 ~ 65g/L, smooth silicone oil 110 ~ 160g/L, temperature 140 ~ 170 DEG C, overfeeding 25m/min;
7) rubber blanket preshrunk: rubber blanket temperature should control at 45 ~ 70 DEG C, and the speed of a motor vehicle is at 30 ~ 35m/min;
8) decatizing and preshrinking process: continuous pressure decator is entered to fabric after mercerising and sizing and carries out decatizing, more than steam pressure 6Pa, 20m/min, expects by steam-shrinkage machine and woollen blanket preshrinking machine to horizontal, longitudinal washing shrinkage of fabric after decatizing, patterns of fabric, effective gate width do processing adjustment;
9) steam-shrinkage: mechanical speed, 15-30m/min, saturated vapor 3-3.5Bar, compressed air 5Bar, to horizontal, longitudinal washing shrinkage of fabric, patterns of fabric, effective gate width do processing adjustment.
Another object of the present invention is to provide the large FIGURED CLOTH of one side adopting above-mentioned method to prepare.
The present invention is owing to have employed above-mentioned technical scheme, the large FIGURED CLOTH of one side that legal system is standby, possesses the characteristic of Lyocell fibers, polyamide fibre, cotton and spun silk simultaneously, have moisture absorption by force, higher swellability, gas permeability, warmth retention property, gloss profit is beautiful, feel is soft, durability, alkaline-resisting and not acidproof, have HEAT SETTING characteristic, the flexural deformation formed when can maintain heating.
Detailed description of the invention
The preparation method of the large FIGURED CLOTH of the cotton 15% spun silk one side of 35% Lyocell fibers 30% polyamide fibre 20%, the method comprises the following steps:
1) raw material prepares: 120N/2 days cotton 20/ thin,tough silk 15 dyed yarns of silk 35/, 20D/2 polyamide fibre 30;
2) weave: install additional at 34 cun of 30G single-side jacquards and specially add shuttle triangle, by 48 tunnels row's pins, design flower pattern, access into yarn way by computerized version figure and color matching accordingly by dyed yarn at computer software inediting, wherein 20D polyamide fibre is done to add shuttle and is used;
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 mercerized, first adds Fe by 100g/L in mercerising process
3+chelated dispersants improves water quality, NaOH concentration 250g/L, 0.2% silkete penetrating agent, by 25m/min normal temperature mercerising, adds 90g/L glacial acetic acid carry out acid-base neutralization, PH Zhi≤7 after alkali lye rolls and washes when open washing, and plays tint retention;
6) secondary sizing: secondary sizing adds the fluffy softener of 60g/L, ice-cold finishing agent 60g/L, smooth silicone oil 140g/L, temperature 150 DEG C, overfeeding 25m/min;
7) rubber blanket preshrunk: rubber blanket temperature should control at 60 DEG C, and the speed of a motor vehicle is at 33m/min;
8) decatizing and preshrinking process: continuous pressure decator is entered to fabric after mercerising and sizing and carries out decatizing, more than steam pressure 6Pa, 20m/min, expects by steam-shrinkage machine and woollen blanket preshrinking machine to horizontal, longitudinal washing shrinkage of fabric after decatizing, patterns of fabric, effective gate width do processing adjustment;
9) steam-shrinkage: mechanical speed 25m/min, saturated vapor 3.3Bar, compressed air 5Bar, to horizontal, longitudinal washing shrinkage of fabric, patterns of fabric, effective gate width do processing adjustment.
One side FIGURED CLOTH project after testing prepared by above-mentioned method is as shown in the table.Examination criteria GB/T 22849-2009, GB18401-20 03 " B " class.
