Background technology
The mode that heat insulating ability underwear fabric large more options far infrared yarn line in the market and air layer tissue combine, its heat insulating ability determined primarily of the still air in the warmth retention property of far infrared yarn, heat generation and air layer tissue.The content of far infrared yarn is higher, and the still air contained in fabric is more, and its heat insulating ability is better.Such as patent CN10880934A discloses a kind of breathable heat insulating fabric, top layer is hygroscopicity cotton, nexine is the warming febrifacient far infrared yarn of tool, be woven together by hygroscopicity cotton fiber, its fabric structure is two-sided air layer structure, but the cost compare of far infrared yarn is high, and the fabric of air layer tissue has solid sense, the comfortableness of dress is also not enough.
In addition, owing to can possess a certain amount of still air in the cavity of hollow type fiber, also have certain heat insulating ability, hollow rate is higher, and insulation rate is also better, and therefore at present heat insulating ability fabric also has and adopts hollow type fiber filament to carry out producing.But the chemical fibre sense of first pure hollow type fiber filament is not too suitable for underwear fabric too by force; Secondly the fluffing of long filament is poor, and its heat insulating ability is still slightly not enough.
Such as patent CN101457434A discloses and a kind of frivolously leads wet thermal insulation clothe material and preparation method thereof, comprise internal layer, skin and intermediate layer, wherein internal layer is made into by Porous hollow dacron thread, skin is made into by natural fiber yarn, intermediate layer is hollow porous polyester silk, and internal layer is connected with flower pattern with skin by the porous polyester silk in intermediate layer, but, because internal layer is that the sense of pure dacron thread chemical fibre is not suitable for underwear fabric too by force.
And for example CN101525796A discloses a kind of static-free thermal fabric and manufacture method thereof, adopt the hollow terylene of degree of hollowness between 20% ~ 30%, the common metal silk of diameter between 0.1cm ~ 0.2cm or conductive fiber and general fibre spin, warping sizing for weaving, obtains after arranging printing and dyeing.Although this fabric is also made up of spun yarn, but, because this fabric is woven fabric, and do not adopt roughing process, in feel, wearing comfort and heat insulating ability, be only applicable to the coat products such as normal laundry, down jackets, work clothes, be not suitable for making underwear.
Summary of the invention
One is the object of the present invention is to provide to be suitable for producing heat insulating ability knitted underwear trousers, the soft knit goods simultaneously with superior water-absorbing fast-drying and heat insulating ability.
Technical solution of the present invention is:
Lightweight heat-preserving knit goods provided by the invention is at least woven by a kind of scribbled and forms, and at least contains hollow polyester short fiber in this scribbled, also can contain one or both in viscose rayon, cotton fiber, wool fiber.This hollow polyester short fiber accounts for 30% ~ 50% of this knit goods gross weight.In this knit goods except above-mentioned scribbled, also containing one or both in viscose rayon, cotton fiber, wool fiber, its tissue can adopt spandex undershirt cloth, rib-loop or cotton wool tissue, and inner side processes through sanding, and fabric weight is between 145 ~ 170 grams/m.Knit goods provided by the invention records insulation rate more than 22% according to JISL1096A method.
This knit goods soft, has superior water-absorbing fast-drying, heat insulating ability and light weight, is particularly suitable for making heat insulating ability knitted underwear trousers.
Detailed description of the invention
In weaving face fabric, the transmission of heat mainly contains radiation, conduction, convection current and evaporation four kinds of transfer modes, and wherein the conduction and convection of heat accounts for more than 50%, therefore effectively suppresses conduction and convection to produce the warmth retention property that just can improve fabric.The heat transfer coefficient of polyester fiber is 0.245, itself has and conducts inhibitory action preferably.The heat transfer coefficient of still air is 0.022, is only about 1/10 of polyester fiber, has best conduction inhibitory action.Utilize the hollow polyester fibre that spinning-nozzle is obtained, by fine for air separation, form the closed state without convection current, still air wherein inhibits heat transfer and cross-ventilation, greatly improves warmth retention property.
The hollow rate of hollow polyester fibre is higher, and still air is wherein more, and heat insulating ability is better.But, after hollow rate is too high, in fiber spinning, fabric braiding and Colour Difference process, more easily destroys its hollow structure, reduce its heat insulating ability on the contrary.Therefore the hollow rate of hollow polyester fibre used is preferably between 15% ~ 50%.In addition, consider hollow polyester fibre because be polyester fiber, from the comfortableness angle of underwear dress, pure hollow polyester fibre is also not suitable for making knitted underwear, therefore controls hollow polyester fibre and accounts for 30% ~ 50% of this knit goods gross weight.
Owing to especially easily producing sweat stain after underwear fabric dress, the fabric of conventional polyester yarn is used not easily to adsorb sweat stain, and lack the ability of moisture absorption heating, in scribbled, therefore preferably also contain one or both in the natural cotton fiber of the viscose rayon of moisture absorption heating, wool fiber, high-hydroscopicity.
Wherein, the thermal conductivity factor of wool is 0.052 ~ 0.055, a little higher than still air, and the natural crimpness of wool fiber easily produces bulk, improve interfibrous short space, thus the still air added in fabric, improve the heat insulating ability of fabric, therefore preferably also contain wool fiber in scribbled.In addition, from the viewpoint of fibre strength, crimpness and spinnability, the shrinkproof mercerising fine wool of optimum fiber length between 70 ~ 100 millimeters.
In this knit goods except above-mentioned scribbled, also containing one or both in viscose rayon, cotton fiber, wool fiber.
Although the still air quantity of possessing in air layer tissue is better than other tissue, but, the still air quantity that sanding layer is possessed after the inboard sanding processing of fabric can weaken the advantage of air layer, secondly, the grammes per square metre of air layer is higher than the single jersey, rib-loop and the cotton wool tissue that adopt same specification yarn, and feel is also corresponding is stiffer than above three tissues.Therefore the tissue of this knit goods adopts single jersey, rib-loop or cotton wool tissue.In order to give the superior percentage elongation of this knit goods and elongation recovery percentage, spandex undershirt cloth is preferably adopted to produce.In order to reach light weight object, also selecting by the count of yarn, controlling fabric grammes per square metre between 145 ~ 170 grams/m.
The hollow structure of hollow polyester fibre defines good capillary effect, because measure wicking height and capillary diameter are inversely proportional to, so capillary is more thin more, its wick effect is better.Hollow polyester fibre only needs a fiber just can form capillary effect.And its degree of hollowness is higher, specific area is larger, and capillary effect is better.Fibre number is thinner, and capillary is more, and capillary effect is better.Therefore preferably use filament denier between 1.5 ~ 4.5 dtexs, the hollow polyester fibre of degree of hollowness between 15% ~ 50%.
Blending is carried out by one or both in hollow polyester fibre and viscose rayon, cotton fiber, wool fiber, both heat insulating ability and the rapid-drying properties of hollow polyester can be had, have again viscose rayon, cotton fiber, the moisture absorption heating of wool fiber and water imbibition, make both have complementary advantages, reach the optimization of performance.
The sand paper of high order number is selected to carry out sanding process to the inner side of this knit goods, the abrasive particle of the random alignment be coated on sand paper in the lower utilization that runs up contacts with fabric tightness, the knife edge that abrasive particle is sharp keen and angle are first by the FRP rebar in yarn, be slit into the ultimate fibre shape of about 1mm, with after through carbon fiber abrasive filaments to ultimate fibre carry out carbon element sanding reach fine hair more carefully, closeer, more even shorter.Formed in fine and smooth tapetum after dress between material inner side and skin and a large amount of close still air without convection current, substantially increase heat insulating ability.
Also can select pin cloth roughing-up machine, by adjustment pin cloth angle and sanding pressure pull-out yarn in fiber after, through carbon fiber abrasive particle silk to pull-out ultimate fibre carry out carbon element sanding, equally also can reach fine hair more carefully, closeer, more even shorter.
Beneficial effect of the present invention is:
The present invention can provide a kind of soft, sense of touch is comfortable, water-absorbing fast-drying, size are stabilized and the light weight knit goods of superior heat insulating ability, be particularly suitable for being used as to produce knitted thermal insulation underwear product.
