Detailed Description
The experimental methods used in the following examples are all conventional methods unless otherwise specified, and materials, reagents and the like used in the following examples are commercially available unless otherwise specified.
In order to solve a plurality of problems of the existing bra, the invention provides a real-time mode, which comprises the following steps: a processing method of a bra fabric comprises the following steps of S1: selecting materials such as cotton/long stapled cotton, real silk, regenerated cellulose fiber and pure or blended yarn; s2: the yarn branch is spun into high count yarn by high count; s3: the method is characterized in that plain knitting is adopted, different D-number spandex is selected according to different cup types and requirements on elastic support, and the spandex is knitted in a plain knitting mode; s4: different requirements of different cup shapes on performance requirements are met by matching and setting different needle number machines, yarn counts, yarn lengths, the D number of spandex and the draft ratio; s5: adopting a shaping process of simultaneously stretching in the transverse direction and the straight direction to form the gray cloth, wherein the transverse stretching value and the straight-pulling opening value of the gray cloth are kept consistent; s6: the adopted spandex has a compression molding setting temperature range of 155-180 ℃ and is added with an anti-yellowing agent to solve the problem of yellowing of high-temperature compression molding. Because the spandex is customized for my own with the adopted spandex, the spandex is applied to the sizing temperature range 165-180 ℃ when the bra mold cup is used for mold pressing (including a die and the back die), and an anti-yellowing agent is added to solve the problem of yellowing of the high-temperature mold pressing.
In conclusion, the gray cloth manufactured by the method has the characteristics of medium elasticity, high-tensile opening degree and four-side elasticity, so that the requirements of different cup shapes of the bra compression molding process can be met, and meanwhile, the fact that consumers are all-around free of constraint when wearing the bra is guaranteed, and the bra has good fitting performance; different performance settings such as different drawing opening degrees, setting of elastic strength and the like can be formed by combining different yarn fineness, yarn length and spandex fineness structure settings, and an optimal combination is provided for the attachment designer when the cup-shaped performance needs to be set from time to time when the bra is made; the specific knitting mode of plain knitting is shown in fig. 1.
Because the high count yarn is 50S to 120S, the gray cloth made of the high count yarn has larger surface area and brings more delicate touch feeling; the skin-friendly and comfortable experience of the consumers is ensured from the material perspective.
The D value of the spandex is 30D-120D, so when the high D value of the spandex is 30D-120D; different cup types can be met, such as: A. b, C different cups such as the small cup and D, E, F, G, etc., and the requirement of elastic support.
Since the number of the high-density needles is 34-44 needles, for example, 34 needles, 36 needles, 40 needles, 44 needles and the like; therefore, the requirements of different cup shapes on the performance can be met by matching and setting different needle number machines, yarn counts, yarn lengths, spandex thickness D and draft ratios;
such as: if 50S ultra-fine Modal +70D spandex is pulled to form a plain weave, the high-stretch/high-stretch opening is required to be set to 230-: the 80S ultra-fine Modal +30D pull frame plain weave requirement sets the middle/high pull opening to 260-350 mm.
As the transverse pulling and straight pulling opening degrees of the gray cloth are 250-350 mm, the yarn length of the gray cloth is not less than 260 mm/100G, the transverse pulling and straight pulling opening degrees of the gray cloth are consistent in numerical value in the mode, the requirement of a pressing die can be met, and the fabric can be guaranteed to have a four-side elastic effect.
The fabric manufactured by the scheme is skin-friendly and comfortable; but also has strong anti-yellowing capability, and particularly, referring to fig. 2, the film pressing is the test of yellowing effect.
The shaping process of the gray cloth comprises the following steps: s7: tentering the gray cloth for one time at the temperature of: 185 ℃ and 195 ℃; the machine speed is as follows: 22-26 m/min; s8: secondary width fixing gray cloth, temperature is: 175 ℃ and 185 ℃; the machine speed is as follows: 28-32 m/min; s9: dyeing the gray cloth of the secondary set; s10: setting at the temperature: 165-175 ℃; the machine speed is as follows: 23-26 m/min. Through the shaping process, the manufactured fabric has enough opening degree, and particularly, referring to fig. 3, a test report about the opening degree of the fabric is provided.
The present invention has been described in detail with reference to the embodiments thereof, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
