Description
技术领域technical field

背景技术Background technique
织造工艺包括机织(也称梭织)、针织、编织和非织造,其中针织又分为经编和纬编。经编是属于针织领域的一种纺织工艺。用一组或几组平行排列的纱线,于经向喂入机器的所有工作针上,同时成圈而形成针织物,这种方法称为经编,形成的针织物称为经编织物。Weaving processes include weaving (also known as weaving), knitting, weaving and non-woven, of which knitting is further divided into warp knitting and weft knitting. Warp knitting is a textile process that belongs to the field of knitting. A knitted fabric is formed by using one or several groups of parallel yarns to be fed into all the working needles of the machine in the warp direction at the same time. This method is called warp knitting, and the formed knitted fabric is called warp knitted fabric.
现有技术中,经编面料的染整工艺已经非常成熟,但是其中还存在一些不足:一是在织布时为了让纱线不起毛,故在织布前的纱线上上了浆,所以染色前应退浆,以便上色,染整工艺中对布料的染色缺乏标准性,从而导致了在染色的过程中温度不同易出现色差,染色效果差。In the prior art, the dyeing and finishing process of warp knitted fabrics has been very mature, but there are still some deficiencies: First, in order to make the yarns lint-free during weaving, the yarns before weaving are sizing, so Desizing should be done before dyeing to facilitate coloring. The dyeing of fabrics in the dyeing and finishing process lacks standardization, which leads to color difference and poor dyeing effect due to different temperatures during the dyeing process.

The uneven tension generated during processing provides the prerequisite for the uniform density of nylon warp knitted fabric to be rolled onto the warp beam, and at the same time, it can avoid excessive shrinkage of the nylon fiber fabric. The dyeing rate is basically balanced above 95℃. Therefore, when the dyeing temperature is determined to be 95 °C, slowing down the dyeing heating rate can also slow down the rate of dyeing nylon with acid dyes and improve the dyeing effect.

具体实施方式Detailed ways
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
请参阅如图1所示的一种经编染整工艺,Please refer to a warp knitting dyeing and finishing process as shown in Figure 1,
S1、定型:为了保证布面尺寸稳定性,对面料进行预定型,为染色做好准备;S1. Setting: In order to ensure the dimensional stability of the fabric, the fabric is pre-shaped to prepare for dyeing;
S2、坯检:坯检主要是观察坯布质量,是否有抽纱、纬挡、死折、黄斑、霉斑等异常;S2. Blank inspection: The blank inspection is mainly to observe the quality of the grey fabric, whether there are any abnormalities such as drawstring, weft block, dead break, macula, and mildew;
S3、退浆:在退浆工艺中加入质量浓度3g/L的氨纶保护剂BFC,退浆温度控制在40-80℃,退浆时间控制在15min;S3. Desizing: Add the spandex protective agent BFC with a mass concentration of 3g/L in the desizing process, the desizing temperature is controlled at 40-80 ℃, and the desizing time is controlled at 15min;
S4、水洗:退浆后要水洗干净;S4. Washing: Wash with water after desizing;
S5、染色:染浴中加匀染剂,用有机释酸剂控制PH优化染色工艺,可有效控制锦纶经编布染色层差,染色效果理想。经轴染色机又称卷轴染色机,由染色压力釜、布满小孔的空心经轴、副缸(配料桶)、循环泵、热交换器、经轴运输车等组成的高温高压染色机,在染色过程中,织物平幅卷绕在带孔的轴芯上,布卷由铁架箍住布卷两头固定,使用高杨程、大流量的专业泵浦使染液正向(自轴芯内向布卷外)或反向(自布卷外向经轴内)强行穿透织物层;S5. Dyeing: Add leveling agent in the dyeing bath, and use organic acid release agent to control PH to optimize the dyeing process, which can effectively control the dyeing layer difference of nylon warp knitted fabric, and the dyeing effect is ideal. Warp beam dyeing machine, also known as reel dyeing machine, is a high temperature and high pressure dyeing machine composed of dyeing autoclave, hollow warp beam full of small holes, auxiliary cylinder (batching barrel), circulating pump, heat exchanger, warp beam transport vehicle, etc. During the dyeing process, the fabric is wound on a perforated shaft core, and the cloth roll is fixed by an iron frame with both ends of the cloth roll. A professional pump with high Yangcheng and large flow is used to make the dye liquor forward (from the shaft core) Inward to the outside of the cloth roll) or reverse (from the outside of the cloth roll to the inside of the warp beam) forcibly penetrate the fabric layer;
S6、脱水:染色后的半成品含水量太高,脱水后保持布面含水率均匀,为后道工序做好准备,经过染色处理的经编起绒面料需要进行脱水处理,经检验测定符合要求后,再进行烘干,然后对面料的平纹面进行碳刷处理,对面料的延展面进行起绒处理,通过碳刷与起绒处理,可使面料起绒面绒感丰满,平纹面手感滑爽。该新型经编起绒面料由于起绒线圈收缩较紧,比一般普通起布的起绒难度大,过大的起毛与碳刷压力易引起竖条和破洞现象,而过轻又难以起绒与碳刷,故经多次试验,选用3%起毛剂和2%膨松剂时,起绒与碳刷作业顺畅,起绒后绒感丰满,碳刷后布面滑爽。最后,经编起绒面料进行定形处理,定形温度为120℃、定形车速为10m/min、超喂10%,定形后成品布面平整,物理和化学性能稳定,双向弹性好;S6. Dehydration: The moisture content of the dyed semi-finished product is too high. After dehydration, the moisture content of the cloth surface is kept uniform, so as to prepare for the subsequent process. The dyed warp-knitted fleece fabric needs to be dehydrated. After inspection and determination, it meets the requirements. , and then dry, then carbon brush the plain surface of the fabric, and raise the extended surface of the fabric. Through carbon brushing and raising treatment, the raised surface of the fabric can be made fuller and the plain surface feels smooth. . The new warp knitted fleece fabric is more difficult to raise than the general raising because of the tighter shrinkage of the raising loop. Excessive raising and carbon brush pressure can easily cause vertical bars and holes, while too light and difficult to raise And carbon brush, so after many tests, when 3% raising agent and 2% bulking agent are used, the operation of raising and carbon brush is smooth, the fleece feeling is full after raising, and the cloth surface is smooth after carbon brushing. Finally, the warp-knitted fleece fabric is subjected to setting treatment. The setting temperature is 120°C, the setting speed is 10m/min, and the overfeed is 10%. After setting, the finished fabric surface is smooth, the physical and chemical properties are stable, and the two-way elasticity is good;
S7、阻燃定型:在织物的表面涂覆一层粘合浆,然后在粘合浆的上表面粘接一层阻燃面料层,织物经阻燃定型后,物理性质和化学性质均较稳定;S7, flame retardant setting: coat a layer of adhesive paste on the surface of the fabric, and then bond a layer of flame retardant fabric on the upper surface of the adhesive paste.

主泵浦的功率的大小直接影响染液的穿透能力,染色流量(即泵浦功率)过小,染液无法完全穿透经轴上的织物,布面会出现大片染花或者渐进色;加大染色流量(即加大泵浦功率),可以在一定程度上减小这种差异,加快了染料分子的运动,有利于染料分子的扩散,从而达到缩小内外层色差的效果;但主泵浦的功率过大,首先会造成电力资源的浪费,其次经过染液喷射口时,由于喷射的压力较大会造成窜布,因此,在选择主泵浦时对上述的现象都要考虑,将主泵浦的效率提到最高,能耗降到最低,染色流量加大,内外层色差减小;但流量太大,会造成能源浪费且容易窜布、移位,染色流量为240m/h,染色温度升高可以增加染料分子在染浴中和纤维上的动能,降低染浴中染料分子的集聚现象。The power of the main pump directly affects the penetration ability of the dye liquor. If the dyeing flow (ie the pump power) is too small, the dye liquor cannot completely penetrate the fabric on the warp beam, and there will be large dyed flowers or progressive colors on the cloth surface; Large dyeing flow (that is, increasing pump power) can reduce this difference to a certain extent, speed up the movement of dye molecules, and facilitate the diffusion of dye molecules, thereby reducing the color difference between the inner and outer layers; but the main pump If the power of the dye liquor is too large, it will cause waste of power resources first, and secondly, when it passes through the dye liquid injection port, due to the large injection pressure, it will cause the cloth to spread. Therefore, the above phenomena must be considered when selecting the main pump. The efficiency of Pu is the highest, the energy consumption is minimized, the dyeing flow is increased, and the color difference between the inner and outer layers is reduced; however, if the flow is too large, it will cause energy waste and easy to channel and shift. The dyeing flow is 240m/h, and the dyeing temperature The increase can increase the kinetic energy of dye molecules in the dye bath and on the fiber, and reduce the aggregation of dye molecules in the dye bath.
同时促使纤维膨化,有利于染料分子进入纤维内部,达到染色匀透的目的。随着染色温度上升,上染率提高,染料上染率在95℃以上左右基本平衡。因此确定染色温度为95℃同时,放慢染色升温速率同样可减缓酸性染料上染锦纶的速率。At the same time, it promotes the expansion of the fiber, which is conducive to the entry of dye molecules into the fiber to achieve the purpose of uniform dyeing. As the dyeing temperature rises, the dye uptake rate increases, and the dye uptake rate is basically balanced above 95°C. Therefore, when the dyeing temperature is determined to be 95°C, slowing down the dyeing heating rate can also slow down the rate of dyeing nylon with acid dyes.
步骤2染色过程中染色温度为95℃,染色流量为240m/h。In the dyeing process of step 2, the dyeing temperature is 95° C., and the dyeing flow rate is 240 m/h.
步骤6烫光过程中温度控制在160度。Step 6 The temperature is controlled at 160 degrees during the scalding process.
步骤1中经编面料层由50%棉纶、40%涤纶和10%氨纶在经编机上编织而成。In step 1, the warp knitted fabric layer is woven from 50% cotton, 40% polyester and 10% spandex on a warp knitting machine.
步骤1中的定型为预定形处理,其中预定形温度为190℃,预定形处理车速为13.7m/min。The shaping in step 1 is a pre-forming process, wherein the pre-forming temperature is 190° C. and the vehicle speed of the pre-forming process is 13.7 m/min.
步骤4中水洗过程中添加松弛剂,保持面料表面的松弛度。In step 4, a relaxant is added during the washing process to maintain the relaxation of the surface of the fabric.
松弛剂配方为:碱5g/L、精练剂10g/L和螯合剂3g/L,水洗温度80℃,面料松弛速度13m/min。The formula of relaxation agent is: alkali 5g/L, scouring agent 10g/L and chelating agent 3g/L, washing temperature 80℃, fabric relaxation speed 13m/min.
步骤5中染色处理使用阳离子染料,阳离子涤纶丝上色,涤纶低弹丝不上色,染色温度为95℃。In step 5, cationic dye is used for dyeing treatment, cationic polyester yarn is colored, polyester low elastic yarn is not colored, and the dyeing temperature is 95°C.
步骤8中拉毛起绒选用了7%起毛剂和1.5%膨松剂。In step 8, 7% raising agent and 1.5% bulking agent are selected for the raising and raising.
步骤11打卷过程中使用定型设备对布料进行定型,定形温度为130℃、定形车速为10m/min、超喂4%。Step 11 During the rolling process, the fabric is shaped by setting equipment, the setting temperature is 130° C., the setting speed is 10 m/min, and the overfeed is 4%.
