The difference between woven interlining and non woven interlining What is a interlining? What is the composition of the lining? Lining, also known as adhesive lining, is mainly used in clothing collar, cuff, pocket, skirt waist, dress edge and suit chest and other parts, generally containing hot melt glue coating. According to the difference of the bottom cloth, the adhesive lining is mainly divided into two kinds: the woven lining and the non-woven lining. 1. non woven interlining , the cloth is not waved timg.jpg Process principle: the viscose used in chemical fiber is formed by high temperature and high pressure. Then the coating machine on the substrate surface a layer of hot melt glue, and then dried to form our non-woven lining. Usage: place the glued side of the lining on the fabric, then melt the glue on the lining by heating the binder or the iron, so as to achieve the effect of bonding on the fabric. Features: cheap, soft, but washable is not good (temperature resistance is below 70 degree) 2. woven interlining, the cloth weaved by polyester The bottom cloth with woven lining is divided into woven or knitted fabric, which is also called knit plain and knit fabric. This fabric is divided into two types: two kinds of knit linings, two sides of projectile knitted linings, four sides of projectile knitted linings, and the width of linings is usually 110cm and 150cm. The woven lining is now using PA coating, it is usually powder glue in the old market, its characteristics are large amount of glue, production process is simple, the disadvantage is that large amount of glue is easy to produce the phenomenon of glue permeation. Now it has been eliminated. The most advanced technology is the non-base slurry dual-point process, characterized by easy to control the amount of glue, strong adhesion, water washing and other special treatment. Now used by most manufacturers. Features: strong strength, good elasticity, and water-resistant.
What is spunbonded non woven fabric? Spunbonded non woven fabric, the main materials are polyester and polypropylene, with high strength, high temperature resistance is widely used in non woven industry. Spunbonded non-woven fabric: after extruding, stretching, forming continuous filament, the filament is laid into a net, and then the net is made into a non-woven fabric by self-bonding, thermal bonding, chemical bonding or mechanical reinforcement. Advantages: High temperature resistance, high temperature resistance (polypropylene fiber can be used in 150 ℃ and polyester can be used in 260 ℃ environment with long term), aging resistance, UV resistance, high elongation, good stability and permeability, corrosion resistance, sound insulation, moth-proof, No poison. Application: The main materials of spunbonded non-woven fabric are polyester and polypropylene. The main products of spunbonded non-woven fabrics are polypropylene and polyester (long fiber, staple fiber) non-woven fabrics. Our most common applications are non-woven bags, non-woven fabric packaging, etc. The identification of spunbonded non-woven fabrics is easier, and the general two-way fastness is good. General spunbonded non-woven fabric rolling point is diamond. The application layer can also make flowers packing cloth, bag cloth and so on, wear resistance, strong handle make spunbonded non woven fabrics as the best choice to make this kind of products.
Thermal bonding is a technology to produce non woven fabric same as needle punch non woven fabric, spunbond, spunlace. The main raw material is PET, PP, PA, natural fiber and so on. There are several thermal bonding systems in use: Calendar bonding Through-air thermal bonding Drum and blanket systems Sonic bonding In thermal bonding process, fiber can be bonded together when reached melt point. Thermal bonding non woven fabric with good performance is more popular than chemical bonding. The advantages of thermal bonding non woven fabrics are as bellowed: 1. low weight. For example, our factory can produce the lowest weight is 16gsm 2. The cloth can be puffy with good hand feeling or bonded into hard hand feeling 3. There is no harmful substances, stable performance, no bad smell, be good for skin 4. Anti - aging antibacterial mold, anti - corrosion guarantee the health and the environment. The process of using a calender for bonding non woven. The fiber is opened and fed into the web former. From the web former, the web is delivered into conveyor, which delivered into the calender rolls. In most conditions, point bonding by embossed rolls is the better way, which can add softness and flexibility of the fabric. Smooth rolls provide bonding flat fabric, which can add strength but reduce drapability and softness. Another way of thermal bonding is using through air ovens. The operation is very easy, it can be easily changed the weight and lofts. The weight and thickness of web decide the length of time in the oven. More time is need if the web is thicker, because the heat need to penetrate to center of the web.
Oxygen is one of the important factors causing food spoilage.Many components in foods are closely related to the presence of oxygen.From the biochemical point of view, fat oxygen oxidation will be defeated, vitamins and a variety of amino acids will lose nutritional value, oxygen will make unstable pigment discoloration or fade;From the perspective of microorganisms, most microorganisms will grow well in the aerobic environment. Even if the oxygen content is as low as 2 ~ 3% in the packaging environment, most aerobic bacteria and facultative anaerobic bacteria can still grow and biochemical reactions will still take place.Therefore, the removal of oxygen in packaging has very important practical significance.Through chemical reaction, in a short period of time to remove oxygen in an airtight container, make food in anaerobic condition (O2 concentration below 0.01%), effectively control the growth of bacteria, mold and other microbes, prevent oil oxidation, thus can effectively keep food color, aroma, taste, prevent vitamins and other nutrients were oxidative damage, prolong shelf life.
Desiccant refers to the substances that can remove the moisture in the moist substances, usually divided into two categories: chemical desiccant, such as calcium sulfate and calcium chloride, etc., by combining with water to form hydrate for drying;Physical desiccant, such as silica gel and activated alumina, is dried by physical adsorption of water.
Needle-punched non-woven fabrics are a kind of dry-laid non-woven fabrics. Needle-punched non-woven fabrics use the puncture effect of needles to reinforce the fluffy web into a cloth. Features of needle punched non-woven fabrics: 1. Flexible entanglement between fibers, with good dimensional stability and elasticity. 2. Good permeability and filtration performance. 3. The hand feels plump and fluffy. 4. Various collection patterns or three-dimensional molded products can be manufactured according to requirements.
pulp airlaid non-woven fabric can also be called dust-free paper and dry-laid non-woven fabrics. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses air-flow method to agglomerate the fibers on the web curtain, and then reinforce the fiber web into a cloth.
