1、 Fabric properties and sources 1. Pure cotton fabric The natural fiber fabric made from natural cotton as raw material and processed by textile technology has the characteristics of environmental protection, skin friendliness, biodegradability, moisture absorption, breathability, and comfortable wearing. It is one of the most widely used clothing fabrics.

Composite spun fibers are high-performance fibers formed through two-component or multi-component melt composite spinning, which can achieve comprehensive properties such as high shrinkage, high elasticity, ultra-fine denier, high strength, and functionality that are difficult for a single fiber to possess. They have outstanding advantages in the industrial field such as structural reinforcement,

The practical functions of polyester fiber are mainly reflected in comfortable wearing, easy maintenance, durability and stability, and strong environmental adaptability, which are its core advantages widely used in the fields of clothing, home textiles, and industry.

Polyester fiber has strong plasticity and processability in textile materials due to its designable molecular structure, adjustable spinning process, and wide adaptability to post-processing. It can be precisely customized according to different application scenarios, functional requirements, and appearance styles, making it the most adaptable and widely used fiber material in modern textile indus

Polyester fiber (polyester) processing needs to combine its physical and chemical properties, focusing on core processes such as spinning, spinning, weaving, heat setting, and post finishing. Key process parameters should be controlled to avoid fiber damage, abnormal product quality, and other issues that may occur during the processing, ensuring smooth processing and product compliance with usage

The main functions of polylactic acid (PLA) fiber are reflected in its four core advantages of environmental protection, safety, comfort, and ease of processing. It is currently a representative bio based biodegradable fiber widely used in textile, medical, industrial and other fields. The following are its specific functional manifestations:

The current core development trend of polyester fiber can be summarized as follows: green, low-carbon and circular, intelligent production and application, integrated industrial structure and globalization. The four main lines work together to promote the industry's transformation towards high quality.

The overall washability of composite spun fibers is excellent, but the specific washability depends on the three core factors of fiber combination type, composite process, and post finishing technology. The washability performance varies significantly in different application scenarios. The following is a detailed analysis:

Polyester fiber (polyester) spinning adopts melt spinning as the mainstream process, and some products use solution spinning. The forming process needs to be strictly controlled around the four core dimensions of melt quality, spinning temperature, stretching and shaping, and cooling and solidification. Specific precautions are as follows:

cPolylactic acid (PLA) fiber is an environmentally friendly synthetic fiber made from renewable biomass. Its optical properties include high transparency, low birefringence, and good gloss tunability, which are closely related to the crystallinity, orientation, and processing technology of the fiber. It has unique application advantages in textiles, packaging, medical materials, and other fields.
