The appearance and wearing comfort of the high-count and high-density fabric are particularly favored in market selection, and particularly, the high-count and high-density pure cotton fabric product has fine and smooth texture, soft and smooth hand feeling, and the fabric is stiff, smooth and clean and has the unique comfort performance of the pure cotton fabric.

According to GB/T5705-2018, the textile cotton textile product terminology, the yarn can be divided into 4 types of coarse yarn, medium yarn, fine yarn and extra-fine yarn. The thick yarns are also called thick yarns, namely yarns with the linear density of more than 30tex (less than 20S); the medium-sized yarn is also called as middle count yarn, namely 14.5 to 30tex (20S to 40S) yarn; the thin yarn is also called thin count yarn, namely 10-14.5 tex (40S-60S) yarn; the extra fine yarn is also called high count yarn, i.e. yarn below 10tex (above 60S). The high-count and high-density fabric belongs to a high-count yarn fabric with the yarn length of more than 60S.

Chinese patent CN 105780257A discloses a spinning method and a post-finishing method of a high-count and high-density home textile fabric, the high-count and high-density home textile fabric is made of pima cotton as a raw material, both warp and weft yarns are 100 double-strand yarns, the warp density is 200 pieces/inch, the weft density is 100 pieces/inch, and the fabric tissue is satin weave tissue. The after-finishing method of the high-count and high-density home textile fabric comprises the following steps: (1) the resin water repellent finishing agent process of the padding method comprises the following steps: the mangle ratio reaches 90%, the resin water repellent finishing agent solution is composed of a mixed resin initial condensate, a catalyst and an organic silicon waterproof agent emulsion, and the contents of the mixed resin initial condensate, the catalyst and the organic silicon waterproof agent emulsion are all 5 g/L; (2) a pre-drying procedure: the temperature is 90-100 ℃; (3) and (3) tentering and drying: the cloth is fed and stretched and dried on a pin plate hot air stenter at an overspeed, the moisture content is controlled to be 10 percent during doffing, and the shrink-proof effect is achieved; (4) and (3) two flat rolling and polishing processes: the roller composition is 2 soft rollers and 1 hard roller, the shuttle mode of the fabric is through a plurality of hard rolling points consisting of soft and hard rollers, the first calendering parameter is friction ratio 50%, linear pressure is stronger than 2000N/cm, steel roller temperature is 50-100 ℃, cloth speed is 50-70 m/min; the second calendering parameter is 30 percent of friction ratio, the linear pressure is stronger than 1550N/cm, the temperature of a steel rod is 140-200 ℃, and the cloth speed is 60-80 m/min; (5) electro-optical finishing process: electro-optical finishing is generally performed by slitting; (6) a baking process: the temperature is 170 and 180 ℃, and the time is 60-90 seconds; (7) a soaping procedure: soaping by using a modern printing anti-sticking soaping agent; (8) a water washing step; (9) a neutralization step; (10) a crease-resistant finishing liquid process of a padding method; (11) cold rolling; (12) wrapping the cloth with a plastic film, and standing at room temperature for 14-18 hours; (13) after the coil is unwound, standing at room temperature for 20-24 hours; (14) a water washing step; (15) a drying process; (16) a high-temperature pressing process; (17) open washing; (18) a dehydration step; (19) heat setting process; (20) and (5) finishing. After the fabric is baked at 180 ℃ after being ironed, the resin and the fibers react violently in a short time, so that the strength loss of the fabric is large, and if the high-count high-density fabric produced by processing 70-inch and finer yarns by the process is used, the strength loss is large, the ironing resistance is low, and the processing flow is long, so that the process is not suitable for producing the high-count high-density ironless fabric.

Chinese patent CN 111455668A discloses a production method of a mosquito-repellent, anti-mite and antibacterial non-ironing energy-saving finished fabric, wherein a yarn-dyed fabric is firstly spun, dyed and woven, then is padded with a mosquito-repellent, anti-mite and antibacterial auxiliary agent in a post-finishing non-ironing process, and is dried and baked at a high temperature. The process flow of after-finishing is as follows in sequence: singeing → desizing → mercerizing → liquid ammonia → permanent press → baking → tentering → preshrinking. In the patent, medium count yarn or coarse count yarn is mainly adopted for producing the fabric, and high-temperature baking is carried out after the fabric is non-ironing to improve the non-ironing property of the fabric. If the patent process is used for producing the high-count yarn fabric, the high-count yarn has low yarn strength and thin yarn, so that the prepared fabric is thin, the liquid content of the fabric is low, the resin cannot be fully reacted by one-time high-temperature baking, the non-ironing property is low, the baking reduction is strong, and the strength loss is large, so that the patent process is not suitable for producing the high-count high-density non-ironing fabric.

Compared with normal yarn count fabrics, the pure cotton high count yarn fabric has the characteristics of lightness, thinness, fineness, coolness and air permeability, belongs to high-grade yarn-dyed fabrics, and can be used for shirts and bedding. However, the high count yarn fabric has low count yarn fabric yarn strength, the padding resin amount is low when resin finishing is carried out, and the baking temperature cannot be too high, so that the non-ironing property can only reach 2.7-2.9 grades on the basis of ensuring the finished product strength, the bottleneck problem is difficult to break through, the crease resistance is poor in the wearing process, and the wearing comfort is influenced.

At present, the problems in the production process of the high-count and high-density non-ironing fabric are as follows:

(1) the non-ironing property grade is low and can only reach 2.7-2.9 grades, so that the breakthrough is difficult to obtain;

(2) the strength loss is large in the production process, and unqualified strength is easy to occur.
