Description
Technical Field
The invention relates to the technical field of clothing fabrics, in particular to a warm-keeping breathable close-fitting clothing fabric and a preparation process thereof.
Background
T-shirts are the necessary single articles worn in summer, and the main stream in the current market is: cotton T-shirts or chemical fibre quick-drying sports T-shirts. The cotton T-shirt has the comfort and skin-friendly performance of natural fibers and good moisture absorption performance, but cannot be denied that the quick-drying effect is not ideal, water vapor generated by a human body cannot be discharged in time in the wearing process, and the sweat is easy to generate sticky feeling of the body, so that uncomfortable feeling is brought, and the wearing experience is influenced; and the moisture remains on the clothing and contacts with the human body, so that the wet and cool of the human body is increased, and the heat of the human body is not easy to maintain. The chemical fiber quick-drying material adopts a fiber or after-finishing process to realize the moisture absorption quick-drying effect, so that the quick-drying performance is maintained in the movement process, and the dryness of the body surface is maintained, but the corresponding disadvantage is that the hand feeling is relatively dry and astringent, and the skin-friendly performance is relatively poor. Therefore, we propose a warm-keeping breathable close-fitting garment fabric and a preparation process thereof.
Disclosure of Invention
The invention aims to provide a warm-keeping breathable close-fitting garment fabric and a preparation process thereof, so as to solve the problems in the background technology.
In order to solve the technical problems, the invention provides the following technical scheme: a preparation process of warm-keeping breathable close-fitting clothing fabric, which comprises the following steps:
spinning in the step (1): collecting PET fibers and PBT fibers with cross hollow sections, doubling, twisting and shaping to obtain yarns;
step (2) weaving: weaving the yarn obtained in the step (1) to form a fabric;
dyeing and finishing in the step (3): and (3) dyeing and finishing the fabric obtained in the step (2) to obtain the clothing fabric.
Further, in the step (1), the specification of the yarn is 100D/96F;
in one yarn, the number of PET fibers and PBT fibers is 48.
Further, in the step (2), a circular knitting machine is used for weaving, and the specification is 34 inches and 32G.
In the technical scheme, 100% polyester functional yarn is adopted, and the yarn and the fabric are sequentially manufactured by using processes of doubling, knitting and the like, and the doubling keeps stable nodes and tension, so that the yarn has good spinnability. The cross sections of the PET fiber and the PBT fiber are in a cross-shaped hollow shape, a large surface area can be obtained by adopting a double-component special-shaped cross section yarn set, a groove is formed through the cross shape of the double-component special-shaped cross section yarn set, the effects of moisture conduction and water drainage are realized, the manufactured fabric can have the effects of quickly coefficient of skin surface moisture and sweat, and the moisture and sweat are discharged to the outer layer to evaporate the skin, so that the dry and comfortable effect of a human body is kept, and the ventilation, moisture absorption, quick drying and heat preservation and sweat discharging capabilities of the manufactured garment fabric are realized.
The combination of yarn structure and components gives the fabric good cotton feeling effect through PBT fiber, adopts a circular knitting machine as soon as possible, has denser needle dial than the conventional organization and finer fabric quality, so that the surface of the fabric presents the cotton velvet granular feeling and luster like natural cotton, and simultaneously has the characteristics of quick drying after moisture absorption, fastness, difficult deformation, convenient washing, simple airing and the like, and is suitable for clothing fabrics worn in commuting and going out. The garment fabric manufactured by the method can be used for preparing T-shirts of standard formats, is integrated with designs based on the T-shirts, and can be suitable for various occasions.
Further, in the step (3), the dyeing process is as follows: dyeing temperature is 120-130 ℃, dyeing time is 60-70 minutes, bath ratio is 1 (50-100), and standing and cooling are carried out after dyeing; two-soaking and two-rolling, and the liquid carrying rate is 40-50%;
soaking in color fixing liquid, soaking and rolling, and drying at 80-100 deg.c;
the dyeing agent comprises 1 to 4 weight percent of dye and 0.5 to 4 weight percent of auxiliary agent; the dye is selected from one or more of active blue MB, active red 195, disperse blue 79, disperse blue 2B, disperse red 195 and disperse red 3B;
the auxiliary agents comprise sodium dodecyl benzene sulfonate LAS, dodecyl dimethyl betaine BS12, fatty acid polyoxyethylene ether AEO9 and dodecyl trimethyl ammonium chloride 1231;
the color fixing liquid contains 20g/L sodium carbonate and 200g/L sodium sulfate.
In the technical scheme, in the dyeing process, the shrinkage of different fibers of PET and PBT is different, so that the local F number fluctuates, and the fabric is endowed with good cotton feel and extinction. The addition of the auxiliary agent and the dye can keep good flatness while keeping the uniform coloring of the fabric in the cylinder.
