Description
Technical field
The invention belongs to textile field, relate to a kind of super soft textiles and uses thereof, be specifically related to a kind of textiles containing polyester fiber that super soft feel was made, had to underwear that can be used for.
Background technology
Along with the change of production development and people life style, underwear fabric will meet consumer requires except pattern, considers that snugness of fit also needs to have good soft feel.The feel of fabric is the concentrated expression of some mechanical performance of fabric to people's the caused stimulation of palm, and the bending of fabric, mantle friction and compression performance are its important parts.
The flexibility of improving fabric can adopt mechanical soft finish and chemical softening to arrange.The method of machinery soft finish is lax fabric construction, through repeatedly flexing and roll compacting reduce the rigidity of fabric and richness and the bulking intensity that increases fabric face.The method that chemical softening arranges comprises softener, sand washing and cellulase treatment.Wherein softener arranges, and is the effect that utilizes softener, reduces in fabric between yarn or the frictional resistance between interfibrous frictional resistance and fabric and staff, is most popular a kind of mode.Softener is divided into amino-modified silicone softener, epoxy-modified silicone softener, organic silicon modified by polyether softener, amino-polyether modified silicone softening agent and block straight chain ternary polymerization modified organic silicon softener etc.Owing to easily there is xanthochromia, the unsettled problem of emulsion in amino-modified silicone softener and epoxy-modified silicone softener, use the textiles smooth feeling after organic silicon modified by polyether softener and the processing of amino-polyether modified silicone softening agent poor, soft feeling is not good.
A kind of method for processing soft of cotton knitted fabric is disclosed in patent CN201010145393.7, soft finishing agent used is amino modified polysiloxane softener, after the method processing, cotton knitted fabric has obtained feel like the soft cotton of water, but as noted earlier, there is the problem that emulsion is unstable, xanthochromia easily occurs processed goods in amino-modified silicone softener.
In addition, in patent CN200710302525.0, mention the mylar that use has hydrophily and flexibility concurrently simultaneously and arrange processing, obtained good feel, but there is the bad and higher problem of price of durability in the softener of general polyesters.
Summary of the invention
The object of the present invention is to provide a kind of super soft feel, low-yellowing and processing technology textiles simple, with low cost and uses thereof that has.
Technical solution of the present invention is: super soft textiles of the present invention is the knitted fabric that contains 20～50 % by weight polyester fibers, this textiles be organized as latitude plain stitch, its Deflection Modulus of Elasticity is 0.2～1.0N/cm
2, the coefficient of kinetic friction is 0.2～0.4.This textiles be organized as pile stitch, its Deflection Modulus of Elasticity is 0.1～0.8N/cm
2, the coefficient of kinetic friction is 0.2～0.4.
Bending rigidity refers to the ability of fabric opposing bending direction change in shape.Be commonly used to evaluate contrary characteristic-pliability.The larger expression fabric of bending rigidity is harder; Consider that bending rigidity changes with the thickness of fabric, the present invention removes bending rigidity with the cube of fabric thickness, obtains Deflection Modulus of Elasticity q and is used for evaluating flexibility.Deflection Modulus of Elasticity numerical value is larger, represents that material stiffness is larger, otherwise, more soft.
Certainly fabric also needs to possess smooth feeling possessing on the basis of flexibility, and the smooth feeling of fabric is relevant with its surface friction property.The present invention adopts the coefficient of kinetic friction to characterize smooth feeling, and when the coefficient of kinetic friction is lower, feel is more smooth.
The average film thickness of the resin molding covering on filament surface in described polyester fiber at least contains organosilicon-polyethers-amino tertiary copolymerized high-molecular-weight compound between 0.005～0.600 micron and in film.The average thickness of resin molding below 0.005 micron time, that is to say that the adhesion amount of macromolecular compound is very few, do not have the effect that reduces friction, thereby feel also just can not get obvious improvement; The average thickness of resin molding is when more than 0.600 micron, and adhesion amount is too much, blocked up, the effect although feel has some improvement, the problem that can bring water imbibition to decline.Preferably 0.050～0.400 micron of the average thickness of resin molding.Consider in addition processing cost and fabric property, preferred 2～10 % by weight (with respect to fabric) of the content of ternary polymerization compound in above-mentioned resin molding.
Polyester fiber of the present invention is conventional polyester fiber (PET) or cationic dyeable polyester fiber (CDP), and filament fiber number is 0.5～2.0 dtex.When filament fiber number surpasses 2.0dtex, feel is difficult to be improved to super soft; Filament fiber number is during lower than 0.5dtex, more difficult on spining technology.
Preferred cationic dyeable dacron (CDP) wherein, it not only self has good dyeability, but also can with the natural fabric co-bathing dyeing such as wool, be convenient to BLENDED FABRIC and simplify dyeing.
In textiles of the present invention, can also contain one or more in the natural fabrics such as cotton fiber, flax fibre, wool, one or more in the regenerated fibers such as viscose (Rayon), acetate fiber, one or more in the synthetic fiber such as polyacrylonitrile (AC), polyurethane (PU).
First select the knitted fabric containing polyester fiber, then in the working fluid that at least contains modified organic silicon softener, this knitted fabric is padded processing, obtains textiles after dry.Here the oxirane, the expoxy propane that in modified organic silicon softener used, contain have emulsification usefulness, and wherein oxirane has preferably affinity with the hydrophilic fibre that contains hydroxyl, and water-wet behavior can be provided; And expoxy propane and WATER REPELLENCY fiber have preferably affinity, can and fiber between produce many contact points; And amino Deng Ge functional group is linear distribution after softener processing, rather than simple random accumulation, realize evenly coated filament, gained textiles has ultralow yellowing, colourless change, without advantages such as oil mark and super softnesses.The consumption of modified organic silicon softener generally between 5～40g/L, adopts one to soak one and roll processing, and baking temperature is 120～160 ℃, time 1～5min.
In the working fluid of configuration, the functional auxiliary agent that can also add other, comprise the water absorbing agents such as the antiseptics such as silver and compounds thereof, organosilicon quaternary ammonium salt class antiseptic, polyesters, one or more in cationic fixing agent are mixed together, give textiles more functional, production method is simple, with low cost.
The textiles being obtained by above method, can improve the feel containing polyester fiber knitted fabric effectively, improves the xanthochromia of fabric.Under normal temperature state, compare with the knitted fabric that does not pass through super-soft processing of the present invention, whiteness changing value is between 0～2.Under the environment of 70 ℃ of * 90%RH, place 240h, compare with the knitted fabric that does not pass through super-soft processing of the present invention, whiteness changing value is between 0～5.
