Description

Technical Field

[0001] The invention relates to the field of knitting, and in particular to a cool cashmere knitted fabric, a manufacturing method thereof, and clothing. Background Art

[0002] Cashmere is a natural fiber and a very precious fiber. It is the finest type of animal fiber. In spinning and weaving, it is closely arranged and has good cohesion, which can lock a lot of air, so it has good warmth retention. Cashmere fiber is not only moderately strong, but also elastic, and has a natural and soft color. The fabric made from it is soft, soft in luster, light and warm.

[0003] However, the weight of traditional thermal fabrics is usually above 280g / ㎡, and the thermal insulation rate of thermal fabrics is 25-30%. The fabrics made of thermal fabrics are relatively thick. With the improvement of consumers' daily living standards, their performance can no longer meet the needs of middle and high-end consumers for light and thin fabrics. In addition, among many textile materials, cashmere has become the representative of autumn and winter thermal sweaters with its soft, light and warm properties, but pure cashmere fabrics or fabrics are not only expensive, but also because of the scales on the surface of cashmere fibers, short and thin fibers, and poor cohesion between fibers, there are serious pilling phenomena during wearing and washing, which greatly affects the appearance quality and service life. Therefore, most cashmere fibers are blended with other fibers, which can not only enhance the anti-pilling effect of the fabric, but also reduce costs and improve the feel of the fabric. However, patent document CN111472086A discloses an ultra-thin cashmere heat-generating thermal underwear fabric, which is made of ultra-fine modal, ultra-fine acrylic fiber, Lycra soluble spandex and white cashmere, and is woven on a large circular machine with a single-sided weft plain needle structure. The weight of the fabric is between 150-160 grams, but the thermal insulation rate can only reach 15%-20%, the warming effect is poor, and the anti-pilling performance is also a suspense issue. It is only suitable for thermal underwear and cannot be used as a sweater for outer wear or inner wear, and its application is limited.

[0004] Therefore, how to provide a cool cashmere knitted fabric, a production method thereof, and clothing to ensure its warmth retention performance while reducing its weight and manufacturing cost, and to make its cool contact feeling meet the requirements of national standards, is a technical problem that the present invention urgently needs to solve.

[0213] Table 3: Performance indicators of dyeing and finishing parameters of cool cashmere knitted fabrics prepared in various embodiments and comparative examples

[0214]

[0215] Through the above charts and attached Figures 1 to 7It can be seen that the weight of the single-sided fabric of the cool cashmere knitted fabric prepared by compact spinning or vortex spinning in the above embodiment is controlled at 160g / m 2 Below, or the weight of double-sided fabric is controlled at 225g / m 2 When it is below, it also has good fabric pilling effect, cool touch feeling, and good thermal insulation effect. In fact, the fabric pilling level can reach the second and third levels, and its cool touch feeling can reach 0.15J / (c㎡.s), or even above 0.21J / (c㎡.s), and the thermal insulation rate can be guaranteed to be above 27%, or even above 38%.

[0216] The above-mentioned embodiments 1 to 14 preferably use low-twist yarns blended from cashmere / acrylic / regenerated cellulose fibers, for example, blended yarns with a twist of 200 to 400 twists / m, among which blended yarns with a twist of 330 twists / m are preferred, which have better thermal insulation properties than the relatively high-twist blended yarns (480 twists / m) used in Comparative Example 2.

[0217] In addition, through comparative analysis of the above-mentioned embodiments with comparative examples 1 and 2, the present application controls the proportions of acrylic and viscose fibers with a large number of micropores and low prices and cashmere within a suitable range, thereby ensuring that while reducing the amount of cashmere used, the prepared cashmere knitted fabric can also have the characteristics of being light, thin, heat-insulating, soft, etc., and while reducing costs, it can combine the advantages and characteristics of three fibers such as acrylic, cashmere, and viscose, especially with the help of the characteristics of the grooves distributed on the longitudinal surface of the viscose fiber and the good thermal conductivity, so that the prepared cashmere knitted fabric also has a good cool feeling, and thus has advantages such as good texture, gloss, light weight, heat preservation, breathability and moisture permeability.

[0218] In addition, the cool cashmere fabric prepared by the above embodiment also has a certain drape, and the formed knitted fabric is crisp, not close-fitting, and has a good sense of bone, which is suitable for fashion (non-close-fitting underwear) and sportswear, and is comfortable to wear, so it can be worn in all seasons.

[0219] In addition, the above-mentioned embodiments optimize the combination of acrylic, cashmere, and regenerated cellulose fibers, so that the fabric has excellent anti-pilling performance. Moreover, through the analysis and comparison of Example 1 and Example 11, it can be seen that: in particular, by adopting expanded acrylic fibers with a high shrinkage rate, a large number of gaps that can retain air can be formed by its greater fluffiness compared to ordinary acrylic fibers, thereby further improving its thermal insulation rate.

[0220] In addition, through the comparison between Example 1 and Example 10, it can be seen that under the same conditions, through the above-mentioned suitable ratio and process of acrylic, viscose and cashmere, the low-twist blended yarn woven by the vortex spinning process has a relatively better thermal insulation rate than the compact spinning process, or can maintain the same thermal insulation performance. This shows that in the blended yarn formed by acrylic, viscose and cashmere, the internal fiber gaps can retain more air, thereby improving its warmth retention.

[0221] In addition, through the analysis of comparative examples 1 to 4, it can be seen that the coolness of the cashmere knitted fabrics prepared therefrom is less than 0.15 J / (c㎡.s), which is unqualified.

[0222] Moreover, in this embodiment, further analysis of Examples 1 to 14 shows that the content of acrylic in the blended yarn is preferably controlled at more than 45%, the content of viscose is preferably controlled at more than 30%, and the content of cashmere is preferably controlled at more than 10%, which can ensure that the heat preservation rate is more than 30%, and the cool feeling is more than 0.15 J / (c㎡.s), for example, a double-sided fabric with a rib structure. In addition, analysis of Example 12 shows that when the acrylic fiber is a bulked acrylic fiber, and a double-sided structure with a convex surface and a flat valley wave structure is used, it can ensure that the heat preservation rate is more than 30%, or even more than 36%, while ensuring that the contact cool feeling is controlled at more than 0.21 J / (c㎡.s).

[0223] Through the analysis and comparison of Examples 6 to 8, it can be seen that: by using a special structure, such as a blended yarn of a long and short composite yarn structure, that is, acrylic and cashmere are used as core yarns, and regenerated cellulose fibers such as viscose fibers, acetate fibers, cuprammonium fibers, etc. are used as sheath yarns to form a composite yarn, the twist of the composite yarn is controlled below 400 twists / m, and the cashmere knitted fabric prepared with spandex has good thermal insulation and a cool touch feeling. The thermal insulation rate can reach more than 30%, or even more than 33%, while ensuring that the cool touch feeling is controlled at more than 0.22 J / (c㎡.s), or even 0.22 J / (c㎡.s).

[0224] In addition, through the analysis and comparison of Example 9, it can be known that the present application can also adopt another special structure, that is, instead of using spandex as the feed yarn, the sheath yarn composed of a blend of acrylic, viscose and cashmere is used as the first yarn, and the core yarn composed of spandex, and the first yarn is directly blended to form a spandex core-spun yarn, and its twist is controlled below 400 twists / m, and the cashmere knitted fabric directly prepared by the spandex core-spun yarn also has good thermal insulation and a cool touch feeling. Its thermal insulation rate can reach more than 28%, or even more than 32%, while ensuring that the cool touch feeling is controlled above 0.21 J / (c㎡.s).

[0225] In addition, through the analysis and comparison of Example 1 and Comparative Example 4, it can be seen that: under the same conditions, when the twist is less than 200 twists / m, it can still maintain good anti-pilling performance and can reach level 2, level 3, etc.

[0226] In addition, its relevant performance can be further improved by further optimizing the spinning method, as well as the weaving and dyeing and finishing processes.

[0227] In addition, the present invention adopts a spandex feeding method to interweave with the blended yarn. By controlling the line length and the drafting multiple of the spandex feeding yarn to 1.2-1.5, adding it to the fabric can ensure that the elasticity of the fabric has good dimensional stability under the conditions of use. The clothing made of this fabric has good shape retention and comfort when worn, can be machine washed, and the cool touch feeling can meet the national standard requirements.

[0228] The above is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, makes any form of equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which does not depart from the content of the technical solution of the present invention and still falls within the protection scope of the present invention.
