Material Selection of Yudeng PU Synthetic Leather Factory

In modern manufacturing and fashion industries, PU synthetic leather has gradually replaced traditional natural leather with its soft feel, good processability, environmental protection and cost-effectiveness, and is widely used in clothing, shoes and bags, automotive interiors, furniture and other major fields. However, in the entire production process of PU synthetic leather, material selection is always a key factor affecting the performance, appearance and cost of the final product.

Just like choosing a solid foundation to build a house, the “foundation” of a high-quality PU synthetic leather is the base fabric material it relies on. The scientific and reasonable selection of materials will directly affect the wear resistance, breathability, softness, ductility and overall texture of the synthetic leather.

Sebagai PU leather manufacturer with many years of experience, Yudeng is well aware of the detailed differences between different substrates. In this article, we will focus on several common and widely used PU synthetic leather materials, including polyester-cotton blends, knitted fabrics, imitation microfibers, imitation cotton flannel, imitation cowhide, non-woven fabrics, etc., and combine Yudeng’s experience in material research and development to help customers understand and select the most suitable material solution for their products.

Polyester-cotton blended material: a choice of both structural stability and skin-friendliness

Polyester-cotton blend is a composite yarn fabric that mixes polyester and cotton in a certain proportion. The base fabric of this type of material is often used in mid-to-high-end application scenarios in PU synthetic leather because it combines the comfort of natural fibers with the strength and stability of synthetic fibers.

Advantage analysis:

Good pulling resistance and shape stability: Polyester-cotton blended materials have high tensile strength and are not easy to deform. They are very suitable for products that require dimensional stability, such as office chair cushions, functional backpacks, etc.

Good skin-friendliness and breathability: The cotton component in the blend can improve the breathability of the fabric, making the synthetic leather more comfortable when worn close to the body.
Suitable for post-processing: Polyester-cotton fabrics are easy to print, emboss and bronze, and are suitable for diverse design needs.

Application example:

Yudeng once provided a PU upper leather with a polyester-cotton blended base fabric for a well-known domestic women’s shoe brand. While ensuring flexibility, it greatly improved the breathability and foot feel of the finished shoes, and the customer praise rate increased by 22%.

Knitted fabrics: Representative of flexibility and soft touch

Knitted fabrics are a kind of fabric woven by winding yarn coils. They are increasingly used in PU synthetic leather, especially in sports and leisure products and soft accessories.

Why choose knitted fabrics?

High ductility: Knitted fabrics have a natural elastic structure and are suitable for leather products that need to fit arcs or irregular structures.

Warm and delicate touch: Compared with woven fabrics, knitted fabrics are softer and skin-friendly, suitable for products that need to come into direct contact with the skin.

Good hygroscopicity and high environmental protection coefficient: Some knitted fabrics are made of natural cotton thread or environmentally friendly recycled fibers to meet European and American environmental regulations.

Applicable scenarios: such as PU yoga mats, children’s bags, and wrist wearable devices, knitted base fabrics are often used as base materials.

Yudeng suggested: When choosing knitted fabrics, you should examine their gram weight (g/m²) and resilience index. It is recommended to use knitted fabrics above 230g to ensure stability after bearing PU coating.

Imitation microfiber material: delicate texture and high-end appearance

Imitation microfiber is a base fabric made of high-density fiber and ultra-fine polyester filament. The surface structure is close to natural suede or frosted leather, and it is often used in the production of high-end PU leather. This type of fabric has both elegant texture and durable performance, and is a popular material that has continued to increase market attention in recent years.

Core advantages:

• High-end appearance: The surface has a delicate velvet feel, and the visual effect is closer to genuine leather.
• Wear-resistant, scratch-resistant, and fading-resistant: Suitable for making handbags, sofas and other products with high service life requirements.
• Environmentally friendly and sustainable development: Some imitation microfibers have adopted recycled materials, which has a positive impact on carbon emissions.

Yudeng case sharing:

We provide customized imitation microfiber PU fabrics for a European luxury sofa brand. The wear resistance coefficient has passed the Martindale 40,000 revolution test, and the entire batch of products has reached the EN ISO 12947-2:2016 international standard.

Imitation cotton flannel: the first choice for warm and comfortable winter

Imitation cotton flannel is an artificial fabric with a short-pile effect. It is used in PU synthetic leather and can effectively improve the hand temperature and softness. It is a common choice for winter products, pet products, home cushions, etc.

Material characteristics:

• It feels like velvet and has excellent warmth retention: it effectively improves the overall warmth of the leather.
• Suitable for composite hot melt adhesive process: it is stably combined with the PU layer and is not easy to delaminate.
• High color acceptance: it is conducive to mass dyeing and customized printing patterns.

Notes:

Although the imitation cotton flannel is soft, it has a slight risk of pilling. Yudeng recommends using anti-pilling finishing agents and encrypted base fabrics, and conducting pilling tests (ASTM D3511 standard) to ensure the quality of the finished product.

Imitation cowhide material: a balance between cost performance and appearance texture

Imitation cowhide material usually refers to PU leather base fabric treated with imitation leather grain technology. Its advantage is that it can simulate the texture and texture of natural cowhide, but it has advantages in cost and environmental protection.

Why do customers prefer imitation cowhide material?

• The cost is more than 70% lower than natural leather
• A variety of leather grains can be achieved: litchi grain, nappa grain, cross grain, etc.
• Uniform structure and more stable quality

Wide range of applications:

The demand for imitation cowhide PU synthetic leather in the fields of car seats, business bags, office desk pads, and simulated leather furniture has increased year by year.

Yudeng takes the advantage of self-developed leather grain templates and can update 10 new textures every month to meet customers’ rapid iteration needs.

Non-woven fabric substrate: light, changeable, and cost-effective solution

Non-woven fabric is a material made by directly bonding fibers by physical or chemical means. It has the characteristics of diverse structures, low cost, and convenient processing. It is one of the most widely used substrates in PU synthetic leather.

Advantages and highlights:

• Wide range of weights and strong applicability (50g~300g)
• Suitable for various production processes such as hot pressing, lamination, and roller coating
• Optional flame-retardant, waterproof, and mildew-proof non-woven fabrics

Yudeng customization capabilities:

Customers can choose different weights and structures (plain, dotted, and diamond embossed) according to their uses. We support OEM customization and can produce samples in as short as 7 days.

How to choose the most suitable PU material according to the purpose of the product?

The choice of materials should be considered comprehensively in combination with specific usage scenarios, cost budget, appearance requirements and environmental protection standards:

Product type	Recommended material	Reason
Women’s shoe lining	Polyester-cotton blend	Skin-friendly and breathable, good fit
Fashion handbags	Imitation microfiber	Visually advanced, wear-resistant and scratch-resistant
Car seats	Imitation cowhide	Simulates genuine leather, stable and elegant
Winter slippers	Imitation cotton flannel	Soft and warm, improve comfort
Children’s schoolbags	Knitted fabric	Good elasticity and light weight
Foreign trade orders	Non-woven fabrics	Controllable costs and fast delivery

Yudeng suggested: Customers can apply for samples of 3 to 5 different substrates in the initial material selection, and judge which one is more suitable for the target market through actual tests (such as wear resistance, tearing, air permeability, VOC detection, etc.).
