hthp dyeing machine
HTHP dyeing machine is the abbreviation of high temperature and high pressure dyeing machine. This type of dyeing machine is generally used to dye chemical fiber grey fabrics and yarn products. And it has the characteristics of high color fastness and uniform dyeing. However, the dyeing process requires high temperature and high pressure steam, and the dyeing machine is subjected to high temperature and high pressure, which is dangerous. Cotton fabrics are generally dyed at normal temperature and pressure.

Different types of HTHP dyeing machine

HTHP beam dyeing machine

​The knitted fabric is wound on a hollow reel warp beam with small holes on the surface, sent into a horizontal cylindrical stainless steel shell, sealed and pressure-dyed, and then processed.
The dye liquor is transported by a centrifugal pump and circulates from the inside to the outside or from the outside to the inside to the fabric layer through the warp beam. This type of dyeing machine may create color differences in the inner, outer and mid-edge of the fabric layer if not handled properly by the operator.

HTHP rope dyeing machine

Features:
  • Sealed and pressure-resistant
  • It can be used at high temperature and high pressure, and can also be used at normal temperature and pressure.
  • Low steam consumption.
  • Applicable dyes and fabrics are wide.

​HTHP overflow dyeing machine

​The dye liquor is drawn from the bottom of the dye tank and enters the overflow tank through the heater. Two or three overflow pipe inlets are installed in parallel in the overflow tank.
The fabric is circulated by the active guide roller and the overflow of dye liquor. During the dyeing process, the fabric is in a relaxed state, the tension is small, the dyeing is uniform, the color is bright, and the product feels soft
This machine is mainly used for the dyeing of synthetic fiber warp knitted, weft knitted fabrics and elastic fabrics. It can be used for high temperature and high pressure dyeing, as well as normal temperature and normal pressure dyeing.

HTHP airflow dyeing machine

​Compared with the traditional liquid-flow dyeing machine, the air-flow dyeing machine circulates the fabric by means of a gas channel containing moisture or water vapor, without the need for dye liquor or water medium to transport the fabric. Almost all fiber materials and their blends can be bleached and dyed.The biggest feature of the airflow dyeing machine is that it greatly reduces the consumption of dyes, chemical auxiliaries and energy.
HTHP airflow dyeing machine is a green and environmentally friendly dyeing equipment with small liquor ratio, low energy consumption and high production efficiency.Fully suitable for the fabric processing range of overflow dyeing machines. It is suitable for dyeing and pre- and post-processing of various loose rope fabrics. It is especially suitable for the processing of some high-end fabrics, such as Modal fiber, Tencel and its blended fabrics, microfiber fabrics, hemp fiber fabrics, polyester and its blended fabrics, etc., which require low tension, soft and plump texture. It can also be used for scouring and bleaching of pretreatment, alkali reduction treatment, and fibrillation, loose drying and soft finishing of Lyocell fibers.

HTHP cheese dyeing machine

​It is belong to HTHP yarn dyeing machine. This machine is designed for production use with high temperature and high pressure. It can be applicable for cotton yarn, polyester yarn, wool yarn etc. Other forms samples such as sliver, lea yarn, bulk fiber, viscose, nylon zipper, ticking buckle tape also can be treated after change dyeing frame.

Twist Test Methods and Influencing Factors

Image
  Twist test is an important part of yarn inspection. It is related to the strength, elongation, appearance, style, etc. of yarns and fabrics. Different yarns have different structural characteristics, and their twist testing methods are also different. Basic concept To understand twist testing, you must first understand what twisting is. Twisting is a necessary condition for yarn formation. Short fibers can be made into yarns with certain physical and mechanical properties through twisting; filaments often need to be twisted in order to increase the tightness between single filaments, facilitate processing, and improve fabric properties. Number of twists Twisting is to cause two cross-sections of parallel straight fiber slivers to rotate relative to each other. The number of relative rotations of the two cross-sections is called the number of twists. Twist Twist refers to the number of twists per unit length of yarn . Twist coefficient In actual production, the twist coefficient is of

Combing Process in Spinning

Image
Before processing cotton, wool, and silk fibers into fabrics, the process of removing impurities and short fibers in the fibers with a combing machine is called combing. The texture, washability and durability of the fabric produced through this process are greatly improved compared with carded fabrics. The following introduces the composition of the combing machine and the combing process. The kinematic coordination relationship of the main parts on the combing machine is indicated by a dial. The disc is mounted on the combing machine and rotates synchronously with the cylinder, which is generally called the indexing disc. The index plate is divided into 40 equal parts along the circumference, and each equal part is 9°, which becomes one index. The working cycle refers to the time interval between the combing cylinder of the intermittent combing machine corresponding to the two actions of combing the whiskers. That is: the first row of needles in the combing cylinder goes to the botto

Garment Dyeing-Special Dyeing Method In Textile

Image
Garment dyeing is a relatively special dyeing process for textiles and garments. Many people may not know much about this dyeing process. In the impression of most people, textile and clothing products are dyed in the fabric period, and garment dyeing is a dyeing process that breaks people’s cognitive limitations on textile dyeing. ​What is garment dyeing ​Garment dyeing means that dyeing the one not in the fabric type but in the garment type itself. The garment type mentioned above include socks, towels, sportswear, shirts, plush toys (without fillers), T-shirts, pants, bathrobes, handkerchiefs, bath mats, carpets, scarves, etc. The material of these garments can be wool, linen, silk and cotton of natural fibers. But most garments are made of cotton or a cotton-rich blends. Garment dyeing imparts vibrant colors to garments. The clothes such as denim garments, tops, sportswear and casual clothing with garment dyeing can provide a distinctive special effect. Garment dyeing method Garmen
