Description

A moisture absorption and perspiration dyeing and finishing process for four-way stretch fabric based on antimony-free polyester technical field

The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a moisture absorption and perspiration dyeing and finishing process for a four-way stretch fabric based on antimony-free polyester.

Background technique

At present, most polyester production enterprises at home and abroad still mainly use antimony-based catalysts. Among the antimony-based catalysts, antimony trioxide, antimony acetate and antimony glycol are widely used, which have a high market share and excellent performance. In the polycondensation reaction of polyester, the antimony-based catalyst can greatly promote the polycondensation reaction instead of promoting the thermal degradation reaction, and is a good catalyst in the polycondensation process. However, antimony is a heavy metal that is harmful to the human body, and is associated with the toxic arsenic, which can cause damage to the liver. Since the production of polyester with antimony-based catalysts is a homogeneous catalytic reaction, the catalyst will remain in the product, and the antimony removal measures adopted by most domestic chemical fiber enterprises have limited effects, so that the processed polyester fibers contain heavy metal antimony; When the dyeing and finishing factory processes polyester, the antimony and antimony catalyst deposited in the fiber will be continuously transferred to the surface of the fiber and the printing and dyeing wastewater under certain conditions. At present, whether it is pretreatment or dyeing in the printing and dyeing industry, in order to save water, the bath ratio is as small as possible, which further increases the enrichment of heavy metal antimony in the waste liquid, and also increases the danger of heavy metals exceeding the standard.

As the "Guiding Opinions on the Development of the "13th Five-Year Plan" of the Chemical Fiber Industry" (hereinafter referred to as "Guiding Opinions") pointed out in the development goals during the "13th Five-Year Plan" period, it is necessary to "further improve the level of green manufacturing, and reduce energy consumption and water consumption per unit added value." The quantity and discharge of major pollutants meet the national binding indicators and relevant standards, the total amount of recycled fibers continues to grow, and the recycling system is further improved.” At the same time, the "Guiding Opinions" also put forward the main tasks of "actively promoting energy-saving and environmental protection technology and equipment, continuously promoting clean production, deepening pollution control, ensuring stable emission standards, and cultivating energy efficiency leaders in the industry." On this basis, polyester catalysts will be developed in the direction of environmental protection, high efficiency, low toxicity and non-toxicity. In the case of comprehensive consideration of economic performance, titanium-based catalysts are antimony-free catalysts that are relatively widely used at present, such as tetrabutyl titanate and isopropyl titanate in the first generation of titanium-based catalysts. Research results show that tetra-n-butyl titanate is used as a catalyst for esterification, the amount of the catalyst is small, the catalytic activity for polycondensation reaction is significantly higher than that of SbAc ₃ and Sb ₂ O ₃ , and the reaction time is significantly shortened. The intrinsic viscosity of the obtained product increases, and the content of terminal carboxyl groups decreases. In recent years, the vigorous development of new titanium-based catalysts has produced second-generation catalyst products, such as titanium-silicon composite catalysts and titanium ethylene glycol, which have good hydrolysis resistance and catalytic effect, and are simple in structure and low in preparation cost. It provides a good basic guarantee for the extensive preparation of antimony-free polyester fibers.

Antimony-free polyester four-way stretch fabric is a two-way elastic woven fabric developed based on antimony-free polyester production technology. The fabric is produced by weaving polyester-spandex core-spun yarn. The core yarn of the polyester-spandex core-spun yarn is spandex fiber, and the stretch and recovery properties of the bare spandex yarn are good, which is the main source of the elasticity of the fabric; the covering yarn is an antimony-free polyester product produced by an antimony-free catalyst, which has 50D and 75D , 100D, 150D and other classifications, when covered, have a certain viscosity, which also provides a small amount of elasticity for the fabric. During the weaving process of antimony-free polyester four-way stretch fabric, the polyester-spandex core-spun yarn is in a stretched state. After the gray cloth is off the machine, the elastic recovery of the elastic yarn causes the width of the gray cloth to shrink. During the dyeing and finishing process, the internal stress of the elastic fabric is completely released after pre-treatment, the elasticity of the spandex yarn is restored, and the fabric is fully shrunk, so that the fabric has the maximum elasticity and the maximum stretchable width.

The four-way stretch fabric of antimony-free polyester has the following technical problems in the dyeing and finishing process:

(1) In the weaving process, in order to prevent damage to spandex fibers, a large amount of oil is often added to protect spandex fibers; these large amounts of oil will affect the subsequent dyeing and setting effects;

(2) Spandex fiber has the characteristics of easy shrinkage when heated, and its shrinkage rate in the dyeing and finishing process is not easy to control;

(3) When dyeing, the selected dyes and dyeing auxiliaries have poor compatibility, which can easily lead to differences in hue; and spandex fibers are easy to absorb a large amount of dyes when dyeing, but the valence bond stress of dyes and spandex fibers is small, and in the subsequent consumption process It is easy to fall off, resulting in poor color fastness.

(4) When the fabric is functionally finished, the color fastness of the fabric is easily affected and decreased.

Therefore, it is necessary to develop a moisture absorption and perspiration dyeing and finishing process based on antimony-free polyester four-way stretch fabric, so as to ensure that the processed fabric not only has good elasticity and resilience, but also makes various technical indicators such as color fastness reach Requirements, the moisture absorption and perspiration performance has reached the highest level in the industry.

Compared with the prior art, the present invention has the following advantages and effects:

(1) The present invention makes the gray fabric of the antimony-free polyester four-way stretch fabric subject to the action of heat and humidity through the tensionless pre-shrinking process, the internal stress of the fabric is eliminated, and the spandex fiber shrinks sharply, so that the warp direction and weft direction of the fabric gray cloth are larger simultaneously. The degree of shrinkage makes the fabric obtain better elasticity on all sides;

(2) The pre-setting process of the present invention draws the width of the fabric to the required width by means of heat setting, and keeps it substantially unchanged in subsequent processing, so that even if the fabric has a certain The shrinkage of the four-way stretch fabric can also maintain the flatness of the cloth surface; and the pre-setting process is marked with an appropriate positive overfeed, which can make the warp direction of the four-way stretch fabric shrink well, and offset the tension of the setting machine through a large amount of overfeed. The influence of the warp elasticity of the fabric makes the warp elasticity and weft elasticity of the fabric basically consistent, thereby preventing the fabric surface wrinkle caused by the sudden shrinkage of the fabric in the dyeing vat, so that the fabric surface always maintains a smooth effect;

(3) The dyeing process of the present invention has adopted macromolecular high-fastness disperse dyes, which can make spandex fibers only retain relatively less dyestuffs after being kept warm for an appropriate period of time in the later stage of dyeing; while polyester fibers are combined with dye molecules After obtaining better valence bond, the dye is not easy to break away from the fiber, and it is not easy to return to the spandex fiber, so that the four-way stretch fabric has better color fastness; in addition, the dyeing process of the present invention adopts dyeing optimizer TF-256 and dyeing The synergist TF-257 can not only improve the cleanliness of the cloth surface without additional washing, reduce the energy consumption caused by the cloth surface cleaning, but also provide a more stable dyeing bath than the conventional ice vinegar system. pH value; spandex degreasing agent TF-109A can effectively remove excess spandex degreasing agent, ensuring that the fabric after dyeing can achieve the expected effect; dyeing process uses dyeing optimizer TF-256, dyeing synergist TF-257 and spandex degreasing agent The combination of TF-109A forms a short-flow same-bath degreasing process, which reduces production links and makes production more efficient and energy-saving;

detailed description

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

Example

Fabric gray fabric: Fabric woven from polyester-spandex core-spun yarn, in which spandex yarn is the core yarn, and the covering yarn is antimony-free polyester yarn produced by antimony-free catalyst.

The gray fabric above is sequentially subjected to a pre-treatment process, a dyeing process and a post-treatment process.

(1) Pretreatment process

The pre-treatment process includes a tension-free pre-shrinking process and a pre-setting process; the tension-free pre-shrinking process includes hot water pre-shrinking treatment of the fabric gray cloth and drying of the hot water pre-shrinking fabric fabric; The molding process is to heat-set the fabric gray cloth after the tension-free pre-shrinking process;

The tension-free pre-shrinking process uses a tension-free pre-shrinking machine to pre-shrink and dry the gray fabric; the hot water pre-shrinking process of the tension-free pre-shrinking machine includes a pre-wetting stage, a pre-shrinking reaction stage, and a vibration pre-shrinking stage. Carry out in the pre-shrinking tank, reaction tank and vibration tank respectively, and the set temperature of each machine tank is shown in Table 1;

Since the fibers are always in a stretched state during the weaving process, the four-way stretch fabric is usually wider in the blank state, and has poor warp and weft elasticity. The tension between the transmission rollers of the tension-free pre-shrinker is very small, and the stress between the fibers will not be increased during the transmission process. At the same time, when the fabric passes through the heating water tanks, due to the heat and humidity, the internal stress of the fabric is eliminated, and the spandex fiber shrinks sharply, so that the warp and weft directions of the polyester four-way stretch fabric shrink to a large extent at the same time, so that the fabric obtains four-sided stretch. Good elasticity; followed by low-temperature tumble drying to make the fabric shrink further when heated, while still maintaining good surface flatness.

The pre-setting process is to pre-set the antimony-free polyester four-way stretch fabric after pre-shrinking without tension. The process conditions are as follows:

The presetting process of the present invention pulls the width of the fabric to the required width through heat setting, and basically keeps it from changing too much in subsequent processing, so that even if the fabric shrinks to a certain extent during dyeing, It can also maintain the flatness of the cloth surface; and the presetting process is marked with 20% positive overfeed, which can make the warp direction of the four-way stretch fabric shrink well, and offset the effect of the tension of the setting machine on the warp direction of the fabric through a large amount of overfeed The influence of elasticity makes the warp and weft elasticity of the fabric basically consistent, thereby preventing the surface wrinkle caused by the sudden shrinkage of the fabric in the dyeing tank due to high temperature, so that the fabric surface always maintains a smooth effect.

(2) dyeing process

The dyeing agent used in this dyeing process includes dyeing auxiliaries and dyes; dyeing auxiliaries include dyeing optimizer TF-256, dyeing synergist TF-257 and spandex oil remover TF-109A; dyes are disperse dyes, including disperse blue 2BLM , Disperse Cuilan S-GL, Disperse Bright Yellow SFN. The dyeing process uses a non-guiding wheel jet dyeing machine to dye the fabric;

The dyeing process prescription is as follows:

Among them, g/L represents the grams of the substance quality contained in 1L dyeing liquor; specifically, 1L dyeing liquor is degreased by using 0.8g dyeing optimizer TF-256, 0.6g dyeing synergist TF-257, and 0.6g spandex Add TF-109A, add the dye corresponding to the prescribed amount, and then add water to make up to 1L.

As shown in Figure 1, the process of the dyeing process is: when the temperature of the dyeing vat of the dyeing machine reaches 40°C, the dyeing auxiliaries and disperse dyes are injected sequentially, wherein the dyeing auxiliaries are injected by direct pumping, and the disperse dyes are injected in proportion Injection, and control the injection flow rate of the dye to ensure uniform injection, to prevent problems such as uneven dyeing caused by too fast injection; after injecting dyeing auxiliaries and disperse dyes, the temperature of the dyeing vat is raised to 95°C at a heating rate of 0.8°C/min, and kept for 10 minutes. Then raise the temperature to 105°C at a heating rate of 0.8°C/min, hold for 10 minutes, then raise the temperature to 130°C at a heating rate of 0.8°C/min, hold for 60 minutes, and then cool down to 80°C at a cooling rate of 1.2°C/min. , then lower the temperature to 60°C, and wash with water for 10 minutes, then lower the temperature to normal temperature, and wash with water for 10 minutes.

Compared with the traditional high-temperature and high-pressure overflow dyeing machine, the non-guide wheel jet dyeing machine uses the water jet to drive the fabric to rotate, which reduces the scratches on the cloth surface, and can eliminate the hemming link before gray cloth dyeing. At the same time, the dyeing machine has a dye liquor leveling device, and has the advantages of variable load adjustment of the cloth tank, high dyeing reproducibility, and good fabric surface quality. In addition, the advanced automatic control device is used to realize the whole process control of dyeing and reduce the dyeing error caused by human factors. The dyeing process adopts a small liquor ratio design, which can reduce energy consumption to a certain extent and meet the requirements of "environmental protection, energy saving, emission reduction, and high efficiency".

Antimony-free polyester four-way stretch fabric is composed of spandex and polyester. Among them, spandex fiber has a faster dye uptake rate and absorbs more dyes, which is prone to problems such as color stripes and color flowers. In the present invention, by adopting macromolecular high-fastness dyes and appropriately prolonging the holding time to 60 minutes, the spandex fibers can be gradually released and migrated to the polyester fibers after the spandex fibers are held for an appropriate length of time in the late stage of dyeing, leaving only relatively Less dye, and polyester fiber obtains better valence bonds after being combined with dye molecules, the dye is not easy to detach from the fiber, and it is not easy to stain the spandex fiber, so that the four-way stretch fabric has better color fastness.

The dyeing process uses dyeing optimizer TF-256 and dyeing synergist TF-257, which can effectively reduce the dyeing rate of spandex fibers and improve level dyeing to a certain extent; moreover, dyeing optimizer TF-256 and dyeing synergist The combination of agent TF-257 can not only improve the cleanliness of the cloth surface without additional washing, reduce the energy consumption caused by cloth surface cleaning, but also provide a more stable pH for the dye bath than the conventional ice vinegar system value. The addition of spandex degreaser TF-109A is to strengthen the removal of excess spandex degreaser and ensure that the fabric surface after dyeing can achieve the expected effect.

(3) post-treatment process

The post-treatment process includes a high-temperature drying process, a soaping process and a low-temperature setting process carried out in sequence;

The process conditions of the high temperature drying process are as follows:

The soaping process prescription is as follows:

Acetate RC 1.6g/L,

Slip agent VS 1.2g/L,

Liquor ratio 1:10.

Among them, g/L represents the grams of the substance contained in 1L soaping liquid; specifically, 1L soaping liquid is made by using 1.6g Accord RC, 1.2g slip agent VS, and adding water to make up to 1L .

The soaping process is as follows: heat up the soaping solution containing soaping aids to 85°C at a heating rate of 1°C/min, keep warm for soaping for 20 minutes, then cool down to room temperature, and soap for 10 minutes. The soaping process can be carried out in the dye vat.

The process prescription and process conditions of the low temperature setting process are as follows:

Among them, g/L represents the grams of the substance mass contained in 1L moisture-absorbing and sweat-wicking finishing liquid; specifically, 1L moisture-absorbing and sweat-wicking finishing liquid is prepared by using 40g of moisture-absorbing and sweat-wicking agent HSD, 1g of citric acid, and adding water to make up to 1L. become.

In order to obtain stable water washing or steam shrinkage, four-way stretch fabrics must be heat-set at high temperature, and high temperature conditions will aggravate the Brownian motion, making the combination of dyes and polyester fibers unstable, causing the valence bond to break, and making it difficult to wash after soaping. The color fastness decreased again. Therefore, the present invention adopts the method of drying at high temperature first, then soaping, and then setting the shape at low temperature. This method realizes the cleaning of the dye absorbed by the spandex fiber and the floating color on the surface of the polyester fiber, and reduces the reduction caused by the setting to the color fastness. , to ensure that the fabric obtains better color fastness.

Specifically, the high-temperature drying process can ensure that the four-way stretch fabric has a good dimensional stability, so as to ensure that the fabric surface remains flat and unchanged after the soaping process, and the warp and weft shrinkage is also in a small range;

The combination of Acosel RC and acidity slip agent VS in the soaping process can effectively remove the disperse dyes attached to the surface of spandex fibers, and at the same time wash the disperse dyes that have not completely reacted on the surface of polyester fibers or have been precipitated due to high temperature drying , so that the product can obtain a better color fastness improvement; and the soaping process is an acid soaping process, which can not only improve the color fastness, but also avoid the traditional alkaline soaping. The link of neutralizing with acid saves the consumption of water vapor;

The setting process after soaping has a lower temperature than the pre-setting temperature and high-temperature drying temperature of the previous process; this low-temperature setting process can supplement the tenter heat setting for the shrunk fabric to meet product requirements; during the setting process The use of large overfeed can ensure that the warp and weft elasticity of the four-way stretch fabric remains consistent; the low-temperature setting process uses a lower setting temperature than the high-temperature drying temperature and pre-setting temperature for setting, which can reduce the decline in color fastness and ensure that the fabric is obtained Good color fastness; the moisture absorption and perspiration agent HSD in the low temperature setting process is a polysiloxane additive, which can endow the fabric with softness, moisture absorption, antistatic and other properties under acidic conditions, and at the same time make the fabric have Good washability.
