Production Of New Type Of Garment Fabric With Superfine Leather Fiber Instead Of Natural Leather

With the progress and development of society, people put forward higher requirements for dress, more advocating and pursuing comfort, health and self reflection. In this situation, the clothing material has already broken through the original function of keeping warm, covering and defending oneself, and then pointed to the functionalization and intellectualization. This trend has promoted the rise of the new type of fabric. In the international market, around the theme of life, health, safety and environment, new clothing fabrics have been developed rapidly, and many varieties have appeared. This has made textile and garment enterprises acquire the vitality of development, and have also satisfied consumers. China's textile industry "fifteen" plan pointed out: "fifteen" period should vigorously develop high value-added products and ecological, environmental protection products, so that the proportion of high-end fabrics to 60%, to meet the needs of garment processing and export. In order to adapt to the development trend of clothing materials, the market pays special attention to the development of new type of fabric.

The meaning of the new type of fabric is embodied in two aspects: one is the purpose of human kindness, that is, functionality; the second is environmental friendliness, the goal is environmental protection. In twenty-first Century, improving the quality of life in the dominant position of economic development, the embodiment of healthy consumption and self-consciousness will become a hot spot of consumption. Those products that can provide mankind with great material and spiritual enjoyment are bound to be popular. Therefore, the functional and intelligent clothing will be favored by new fashion fabrics. At present, the new clothing fabric products aimed at improving the quality of human life have emerged in large numbers.

While human beings are concerned about the quality of their own lives, the consciousness of protecting the ecological environment is also constantly strengthening. It has become a common understanding that the production of green fabrics has become green. The use of "green technology" for garment fabric production has become an important means to obtain new types of fabric.

Innovative value of new fabrics

The new fabrics commonly used in the market, though good in performance, are ultimately processed by the finishes of minerals and plants. Guangzhou Yilong science and technology comprehensive service company has been developing leather fabrics for many years, breaking through the laboratory stage and gradually moving towards the market oriented production stage of products. Its raw material is cowhide leftover material, which is an environmental protection project that belongs to resource regeneration.

Dermis is mainly composed of collagen fibers, elastic fibers and reticular fibers, and is called fibrous components.

1. characteristics of collagen fibers

Collagen fiber is the main fiber in the dermis, which is composed of collagen, which accounts for 95%~98% of the total weight of the dermis. After being boiled in water for a long time, the fibers degrade and form a colloidal substance, that is, gelatin or gelatin.

The length of collagen fiber can not be determined because it is continuous. The diameter of collagen fiber bundle is 20~150 micron m. Each fiber bundle is made up of parallel rows of fine fibers (Primitivefiber), with a diameter of 2~5 m. This fine fiber is also made up of smaller fibrils (Fibril), also called microfibrils, and its diameter can be as small as tens of nanometers (usually 20nm). The fibrils can be further split into finer fibrils (Filament) or subfibrous fibers (Subfibril) with a linear degree of about 3nm. Fibrils are also composed of Protofibril fibers with a linear degree of 1.2 to 1.7nm.

Collagen fibers interweave in the dermis. The thicker fiber bundles are sometimes divided into finer fiber bundles. These finer fiber bundles sometimes combine with other fiber bundles to form another larger fiber bundle. In this way, they are constantly divided, combined, divided and crisscrossed, woven into a special three-dimensional network structure, making the raw leather and its products (leather) have very high mechanical strength. Collagen fibers can form bundles, which is one of its characteristics.

The closer the collagen fiber bundle to the epidermis is, the smaller the fiber is, and when it extends to the surface of the grain, it becomes more compact. The fiber bundles in the middle part of the dermis are thicker, more compact and have a certain type of texture. The collagen fiber bundles near the subcutaneous tissue become small and loose.

2. characteristics of elastic fibers

This fiber is relatively small in the dermis, only 0.1% to 1% of the tare. The elastic fibers are very thin, and their diameters are not more than 8 m, which are made up of elastin. In morphology, the difference between elastic fiber and collagen fiber is that elastic fibers should be branched without forming fiber bundles. The difference in nature is that the elastic fiber has great elasticity, and has certain boiling resistance of acid, alkali and heat resistance, and the elastic fiber will not become glue after boiling. It is mainly distributed in the upper dermal layer (papillary layer), hair follicle, fat glands, sweat glands, blood vessels and vertical hair muscles.

In the dermis near the subcutaneous tissue, the number of elastic fibers distributed less, and in the middle part of the dermis is less. There are also elastic fibers distributed in the subcutaneous tissue, and the number varies with animal species. Elastic fibers play a supporting role in the dermis. As a result, it has a certain effect on the softness of leather. In the process of production, the destruction of elastic fibers around the hair follicle is also helpful for enzyme depilation.

3. characteristics of reticular fiber

The fibers are distributed at the junction between the epidermis and the dermis, forming very dense omentum and forming a loose web on the surface of the collagen fiber bundle, which traps the fiber bundles and protects them. In the form, the Internet fiber is also branched and United. It is very similar in nature to collagen fibers, so some people think that reticular fiber is a "variant" collagen fiber.

In the leather made from all animal skins, cow leather is the most widely used, the animal fiber content is the most abundant, and the leftover material is the largest, so it is the most suitable to extract animal fibers from the cattle hide leftover material. In the past, due to the influence of funds, technology and many other factors, a certain amount of resources were wasted. Now, through certain technical means, it turns waste into treasure and has high utilization value.

New fabric technology stability

The technology and method of acquiring dermal fiber through the Guangzhou Yilong science and technology comprehensive service company can make the real leather fabric meet the following requirements:

1. the diameter of the fiber can be micron (about 50~80 m), and the length is 8 to 25mm. It can really become a single fiber (not a fork), rather than a fiber bundle (n single fiber polymer).

2. thoroughly solve the problem of entanglement coefficient in the spunlace process, such as the knot, bifurcation, uneven length and uneven thickness of the original fiber bundle.

3. it solves the problem that the thickness of animal fiber is not uniform and can not produce thinner products. It can produce products of 0.1mm thickness and basically meet the thickness requirements of new fabrics.

4. because of many problems such as air permeability, strength, thickness and so on, the new leather fabric has wider application and development prospects than traditional cattle leather.

5. according to the fabric's softness, comfort and excellent similarity to human skin, it can be made into men's and women's clothing and infant clothing. According to its non thermal deformation characteristic of high temperature 300C degrees, fire fighting uniform can be made for first-line fire officers and soldiers. Other types of clothing and special products can be developed according to environmental protection and other characteristics.
