Problems solved by technology

Although resin finishing can improve the effect of anti-wrinkle and anti-shrinkage, it damages the fiber and is not soft enough
The calendering treatment uses physical methods to flatten the yarn on the surface of the knitted fabric under the action of gauge pressure, and the vertical fluff is pressed down, the surface of the fabric becomes smooth and clean, and the degree of diffuse reflection of light is reduced, thereby The luster of the fabric is improved, but this method has a short durability and has obvious disadvantages: the cotton fiber has obvious elongation under pressure, the greater the roller pressure, the more the longitudinal elongation of the fabric, and this elongation Temporarily stabilized under the action of heat, which has a certain impact on fabric specifications
The other is liquid ammonia mercerizing, which is relatively rare in China. This method can achieve multiple effects such as shrink resistance, wrinkle resistance, softness and no reduction in strength, but it requires special liquid ammonia mercerizing equipment, which is expensive and expensive. The process is long, and liquid ammonia is a poisonous gas, which requires special protection during production. In addition, the process is not mature enough, and many fabrics are not suitable for production by this method, such as: black dye varieties, discoloration after liquid ammonia mercerizing; If the shrinkage is too serious, it is easy to cause curling or creasing on the liquid ammonia machine; there are also T / C fabrics, which are easy to generate static sparks and cause explosions; there are also varieties that may produce curling or weft shrinkage in other dyeing and finishing processes. Can cause severe hemming or shrinkage after production

Embodiment 1

[0019] Example 1: 40S / 1 compact cotton double-sided 21.77kg, water ratio: 1:16, color: bleached.

[0020] The raw material cloth is prepared and smelted by the conventional raw cloth, and then put into the Fong’s SYN-50 airflow machine for bright treatment. The machine conditions are: single cloth, pressure difference 90%, fan 27%, machine speed 25m / The water ratio of 2'22" bright treatment is 1:16, add HAc 0.348kg, NaAc 0.174kg, INDIAGE MAXL 0.195kg to the water, pH value is 42, treatment temperature is 55℃, treatment for 50 minutes, after treatment, use Na 2 CO 3 Neutralize the washing water, add white to neutralize the tank after brightening. After normal drying, the cloth is fixed and softened in a hot air sizing machine. The setting conditions are: 150°C×6+130°C+107°C, machine speed: 20m / min; Slurry formula: 20g / l silkasoft ra, 40g / l smartil vst, 0.3g / l malic acid, the solvent is water, the excess rate is 80%, after setting the shrinking machine, the machine speed is 1...

Embodiment 2

[0021] Example 2: 40S / 1 compact cotton double-sided 20.87kg, water ratio: 1:15, color: deep black

[0022] The raw material cloth is prepared and smelted by the conventional raw cloth, and then put into the Fong’s SYN-50 airflow machine for bright treatment. The machine conditions are: single cloth, pressure difference 90%, fan 27%, machine speed 25m / 2'20". The water ratio of bright treatment is 1:15, add HAc 0.313kg, NaAc 0.156kg, INDIAGE MAXL 0.145kg in water, treatment temperature is 55℃, treatment time is 50min, pH value is 4.1, after treatment use Na 2 CO 3 Neutralize and wash water, brighten and dye out of the vat normally, then dry the cloth normally, and then carry out fixed-sizing finishing and soft finishing in the hot-air sizing machine. The setting conditions are: 150°C×6+130°C+107 ℃, machine speed: 20m / min; the softening agent for softening and finishing is made of: 25g / l silkasoft ra, 30g / l smartil vst, 30g / l kepler427 (fixing agent), 0.3g / l malic acid, and th...

Embodiment 3

[0023] Example 3: 40S / 1 compact cotton double-sided 19.96kg, water ratio: 1:18, color: floral yarn washing water

[0024] The floral yarn is pre-determined, the greige cloth is sewed, and it is desoftened until dripping in the vat. After washing, it is brightened. The brightening treatment is produced in the SME water flow vat of Yongyi Xinda. The operating condition is 7psi and the machine speed is 45m / 1 '40". The water ratio of bright treatment is 1:18, HAc 0.359kg, NaAc 0.18kg, INDIAGE MAXL 0.199kg are added to the water, the pH value is 4.3, the treatment temperature is 55°C, and the treatment time is 80min. Na 2 CO 3 Neutralize the washing water, take it out of the vat after bright treatment, dry the cloth normally, and then carry out fixed and soft finishing in the hot air sizing machine after drying. The setting conditions are: 150℃×6+130℃+107℃, machine speed : 25m / min, the softener slurry for softening and finishing: 15g / l silkasoft ra, 35g / l smartil vst, 0.3g / l mali...

Abstract

The invention discloses a silk cotton knitted fabric and a production method thereof. The silk cotton knitted fabric is formed by performing special bright treatment and a soft finish process on cotton and elastic cotton knitted fabrics and allowing the fabrics to pass through a squeezing machine (a cloth face is flatly pressed to improve mirror reflection so as to improve glossiness), so that the silk cotton knitted fabric obtained by treatment of the process is silkily soft and smooth, does not have hair on the cloth face and has elegant glossiness and a liquid-state cotton effect with excellent drape; the resilience of cloth is greatly enhanced; and the content of formaldehyde in the cloth is less than 20mu g / g JISL (04), and the color fastness reaches American association of textile chemists and colorists (AATCC) level-4 numerical value. Compared with the conventional mode, the production method has the advantages of short flow, no need of special production equipment and low cost and is easy and convenient to operate.

Description

Technical field: [0001] The invention belongs to the field of dyeing and finishing of textiles, and in particular relates to a silk cotton knitted fabric and a production method thereof. Background technique: [0002] Silk products are characterized by luster and better drapability, but the cost is relatively high. To make ordinary cotton and elastic cotton products achieve silky luster, the current industry mainly uses alkali mercerizing, biological enzyme polishing, resin finishing, calendering treatment and liquid ammonia treatment. Caustic soda mercerizing can improve the luster of cotton and elastic cotton products, but it lacks anti-wrinkle and soft effects, and the hand feeling will gradually become harder with the strengthening of mercerizing conditions. Although resin finishing can improve the anti-wrinkle and anti-shrink effect, it damages the fiber and is not soft enough. The calendering treatment uses physical methods to flatten the yarn on the surface of the k...
