In the embodiment, cotton, hemp and cashmere are all natural fibers, the hemp fibers have the functions of antibiosis, bacteriostasis, mildew resistance and deodorization, and the cashmere has the excellent characteristics of lightness, thinness, softness, warmness and smoothness, is a high-grade textile raw material, is expensive and is called as gold fibers. The base weft uses cotton and hemp, so that the base strength of the fabric can be ensured, and the cotton and cashmere are used in the cashmere weft, so that the hand feeling of the cashmere can be highlighted.
Cotton fiber and hemp fiber belong to vegetable fiber, and the characteristic is that alkali-proof is not acid-fast, and the cashmere belongs to protein fiber, and the characteristic is that acid-proof is not alkali-fast, and the condition difference of dyestuff is very big during its dyeing, and the unified dyeing of later stage can lead to cotton, the unable or cashmere damage of coloring of hemp to be serious. Therefore, the blended cheese is dyed respectively in the application, so that the damage to the fabric caused by later-stage printing and dyeing is avoided, the cashmere fiber is protected to the maximum extent, and the homochromatism of the dyeing of each fiber can be better controlled. The method for adjusting the dyeing sequence solves the problem of cashmere dyeing damage.
The traditional blended fabric made of various raw materials can be subjected to sizing and desizing. In step S1, a single yarn plying process is used to enhance wear resistance, thereby eliminating the need for sizing and desizing.
The task of drafting is to make the warp yarn on the beam pass through the drop wire, harness wire and reed according to the requirement of the fabric, so as to form shed when weaving, and introduce the weft yarn to weave the required fabric, thus it can stop in time when the warp yarn breaks, and will not cause weaving defect. The contracted width is sprayed with steam through a steam spraying box, and the drying cylinder is contracted for drying, so that the contracted width of the cloth width reaches 148-150cm from the original 160.2 cm. The brushing effect is that the ground weft and the warp are interwoven to form a ground fabric, the pile weft and the warp are interwoven to form a row of pile loops, the pile loops are cut off by cutting, and after brushing and finishing, the surface of the fabric forms a vertical corduroy pile strip.
According to the cotton, hemp and cashmere production process, the warp yarns and the weft yarns are blended to obtain the cheese, then the three types of cheese are dyed respectively, then warping, starching-free shaft combining and drafting are performed on the warp yarns in sequence, then the processed warp yarns and weft yarns are woven to obtain a fabric primary product, the fabric primary product is subjected to amplitude shrinking treatment, cutting and brushing treatment in sequence, and then the fabric softness is improved through air washing to finally obtain a finished fabric. The specification of the cotton, hemp and cashmere yarn-dyed cashmere corduroy is as follows: (14.5 tex. times.2). times.14.5 tex. times.2) +27.8tex, 330X 496 pieces/10 cm, 16 strips/2.5 cm.
Further, in step S3, the warping beam is configured to: 662 x 4 axes, 661 x 4 axes; the warping tension is segmented into: the number of the front, middle and rear tension hanging rings is 1, 0 and 1 respectively, wherein the rear section does not use a heavy hammer; the warping speed is 340 plus 360m/min, and the humidity is 65-70%.
In the embodiment, the speed within the numerical range can meet the requirement of higher production efficiency and reduce the yarn breakage rate. Above this speed range, the yarn breakage rate increases, below this speed range, the production efficiency decreases, the influence of speed to the whole warp process is shown in table 1. The humidity range is 65% -70%, the winding density of the yarn is too high above the humidity range, so that the bulkiness of the yarn is reduced, hairiness and flying on the surface of the yarn are increased and the strength is reduced below the humidity range, and the influence of the humidity on warping is shown in table 2. The heavy hammer is used for straightening the yarn to avoid yarn knotting, and the tension of the yarn is adjusted by adjusting the number of the tension rings.

TABLE 2 Effect of humidity on warping
Further, in step S4, the merging process includes:
s41, pressing yarns by using a pressing roll, and pressing 5KN-8KN by using the pressing roll;
s42, combining the shafts; the parallel winding tension is 0.3MPa-0.5MPa, and the beam winding density is 0.4g/cm 3 -0.5g/cm 3 The vehicle speed is 40m/min-50 m/min.
In the embodiment, single size groove parallel production and whole warp beam parallel production are adopted, and the requirement of the number of yarns is met. Sizing is avoided in the process, the squeezing roller pressurizes 5KN-8KN, and poor hairiness on the yarns can be bound by adding small pressure, so that the yarns are smooth and flexible, and the strength and the elongation of the yarns are not influenced. The fabric does not need sizing, adopts ply yarn to weave, improves the yarn strength and wear resistance, and does not need sizing, so that the damage of sizing coating yarn and penetration yarn to fiber adhesion influence elongation and yarn desizing to the yarn is avoided.
Further, in step S5, six-page healds are used, the weaving method is: 323616525414 (fly-through); specification of dropper: 165 x 11 x 0.3 mm.
Further, in the weaving process of step S6, the fabric weave adopts 16 yarn corduroy weave structure, and the fabric is woven by six pages of weaving machine, the lifting sequence is: 13536452463645, respectively; opening time: 290 °; the upper machine tension is 1.8 KN; the height of the warp stop frame is 8cm, and the height of the back beam is 5cm 8 cm; the loom speed is 550 r/min.
In the embodiment, an RFJA20-230 air jet loom is adopted for six-harness weaving. The conventional weave structure generally needs four healds to weave, uses six healds to weave in this application, because corduroy falls mao easily, therefore specially designs a new card board picture, can increase the consolidation point number of warp and woof, makes the fine hair consolidation point of product more firm to reach the effect that is difficult for falling mao. The weave and pattern of the fabric of the present application are shown in figures 2-3.
