Types of warp knitting machine

Warp knitting machine is a kind of knitting equipment widely used in the fields of industry and clothing. It is a knitting equipment that uses multiple parallel yarns for warp knitting. It is efficient and durable, has a long service life, and helps many companies improve the production efficiency of knitted clothing. It is a very worthwhile investment.

What is a warp knitting machine?

A warp knitting machine is an industrial equipment that weaves with warp yarn as the main line direction, and is an important branch of knitting machinery. It uses a row of needles to weave the warp yarn in a loop at the same time to form a mesh, dot or flower structure fabric. Compared with weft knitting machines, warp knitting machines have faster weaving speeds and higher dimensional stability of finished products, making them suitable for large-scale continuous production.

Types of warp knitting machines

Warp knitting machines can be mainly divided into the following categories according to their structure, function and purpose:

High speed intelligent plush fabric raschel machine

Model: GE385, this machine is specially developed for producing apparel fabric, plush toy, home textile and upholstery fabric, etc.

Full-width weft insertion warp knitting machine

Model: GE2269, The fabrics produced are mainly interlinings, light box fabrics, geotextile, glass fiber and other engineering fabrics, mainly used in.

High speed net Warp Knitting machine

Model：GE2393, this machine is used for knitting shade net, knotless fishing net, chemical fiber net fabric, safety net, sports net, anti-collision.

High speed double needle bar warp knitting machine

Model: GE2285, this machine is specially developed for producing backing layer fabric, short pile plush fabric and spacer fabric.

Numerical controlled tricot high speed machine

Model: GE2268,Tricot warp knitting machine is a high-speed textile machinery commonly used to weave relatively simple warp knitted fabrics.

The role of warp knitting machines

The core role of warp knitting machines is to form structurally stable fabrics along the set path of yarns. They are often used for:

Mass weaving of textile raw materials

Replacing traditional woven fabrics to improve fabric elasticity and breathability

Weaving special fabrics such as mesh structures, lace patterns, and three-dimensional fabrics

Providing structural support for composite materials or functional materials

Functions of warp knitting machines

Modern warp knitting machines have the following functional modules:

Warp feeding system: Automatically controls yarn tension and supply

Knitting system: Adjustable needle type and needle length to determine fabric density

Transverse movement system: Controls the transverse movement of the yarn guide needle to achieve a variety of patterns

Electronic control system: Supports patterns Programming, fault diagnosis, etc.

Weft insertion system (optional): used for weft insertion weaving function

Automatic tension and shutdown protection system: to ensure stable operation

Application areas of warp knitting machines

Warp knitting machines are widely used in many industries:

Clothing fabrics: mesh fabrics, swimsuit fabrics, sportswear stretch fabrics

Home textile fabrics: curtain fabrics, mosquito net fabrics, sofa fabrics, lace

Industrial fabrics: sunshade fabrics, tent fabrics, filter fabrics, fireproof fabrics

Automotive interior materials: seats, ceilings, sound insulation layers

Medical fabrics: bandages, medical nets, elastic bandaging fabrics

Shoe materials/bag fabrics: sandwich mesh fabrics, jacquard fabrics, upper fabrics

What products are suitable for warp knitting machines?

Warp knitting machines are suitable for the following categories of products:

Mesh fabrics: hexagonal mesh, diamond mesh, ultra-thin mesh

Stretch fabrics: swimwear fabrics, sportswear fabrics

Lace fabrics: wedding dresses, underwear fabrics

Industrial fabrics: sunshade nets, insect-proof nets, fireproof fabrics

Automotive fabrics: ceiling fabrics, seat breathable layers

Medical fabrics: elastic bandage fabrics, breathable adhesive tape base fabrics

What is the typical capacity of a warp knitting machine?

The capacity of a warp knitting machine depends on the following factors:

Operating speed: 300 – 1,200 RPM (revolutions per minute)

Fabric width: 66″–180″ (inches) or customized

Daily fabric output (single machine): 300 – 2,000 meters/day

Monthly output (3 shifts): up to 50,000 meters or more (depending on the type of fabric)

Is a warp knitting machine difficult to operate?

For skilled operators, warp knitting machines are not complicated. Most modern warp knitting machines are equipped with electronic pattern control and automatic warp feeding system, which reduces the operating threshold.

Training cycle: It takes about 3-7 days for novices to master basic operations

Common training content:

Equipment startup and shutdown process

Yarn replacement and threading method

Pattern pattern setting

Simple fault diagnosis and maintenance

Is the warp knitting machine suitable for small and medium-sized factories?

Yes! Especially:

Small and medium-sized underwear, mesh or functional fabric factories

OEM/ODM customized factories

Traditional fabric factories that want to transform automation and increase product added value

It is recommended to choose domestic equipment with simple structure, convenient maintenance and easy-to-buy accessories as a starting point, such as Shengtai, Jingwei, Changxing and other brands.

How to maintain a warp knitting machine?

1. Clean the machine regularly every day

It is recommended to remove flying flowers and oil stains before leaving get off work every day to keep the machine clean.

2. Lubricate and maintain the machine regularly

Regularly oil the bearings and needle beds to prevent rust.

3. Periodic tension inspection

Regularly check the tension wheel and clamp of the warp feeding system to ensure their normal operation.

4. Maintain the electronic control system

Regularly check the control box circuit, remove static dust, and ensure safe maintenance.

5. Check/replace vulnerable items

Replace steel needles, yarn guide needles and flower discs in time to avoid other faults.

6. Avoid moisture and rust from affecting use

Keep the machine room dry, avoid long-term shutdown and unsealed to avoid losses.

Guide to the use of warp knitting machines

The following is the basic process of using a warp knitting machine:

1. Prepare the required yarn first

First, you need to select the appropriate yarn and warp it;

2. Secondly, thread the yarn

According to the yarn count, guide the yarn to the comb and yarn guide needle.

3. Set pattern parameters reasonably

Input or adjust pattern program according to pattern parameters.

4. Regularly adjust tension

Adjust warp tension and traction tension as needed.

5. Start the machine

Observe whether the machine runs smoothly and prepare to start the machine;

6. Monitor the use process

Pay attention to yarn breakage, knotting, skipped stitches, etc. during the process to avoid affecting production;

7. Perform winding processing in time

Wrap and store according to fabric length;

8. Shutdown record

It is recommended to record production and clean the equipment every day.

Conclusion

Warp knitting machines are an indispensable and important equipment in the modern knitting industry, with significant advantages such as high production capacity, stable fabrics, and wide application. Whether it is mesh, lace or functional fabrics, its high efficiency and automation characteristics bring significant production benefits to medium and large factories. To choose a suitable warp knitting machine, a comprehensive evaluation should be made based on its own product type, production requirements, budget and technical personnel.
