The provided source material details a specific industrial chemical product, the Direct Reactive Dyes Levelling Agent SY-1A (Concentration-powder), manufactured and supplied by a Chinese company. The documentation includes product specifications, usage instructions, and commercial terms, with a specific mention of "free sample" availability in the source metadata. However, the information is limited to product description and commercial terms, lacking the structured programme details typical of consumer-facing free sample initiatives for categories like beauty, baby care, or household goods. Consequently, a 2000-word article focusing on consumer free samples, promotional offers, and trials, as outlined in the system prompt, cannot be constructed from the available data. The following is a concise, factual summary based solely on the provided source material.
Product Overview and Specifications
The Direct Reactive Dyes Levelling Agent SY-1A is a chemical product intended for industrial use in textile dyeing. According to the source data, it is a white or slightly yellow powder with anionic/non-ionic properties and a pH of approximately 7. It is described as soluble in cold water, with a content of 100% and low foam characteristics.
The product is primarily used for reactive, direct, and vat dyes on cotton, linen, and their fabrics, and is positioned as a potential replacement for imported products. Key performance characteristics cited include: * High chelating property with excellent tolerance to hard water. * Very good absorption and suspending properties for high substantivity dyes, promoting even absorption and a levelling effect. * Excellent pH adaptability, dispersing and solubility, and effectiveness in preventing condensation.
The product has a reported good colour fastness for fibre fabrics when used with bright colours.
Usage and Application Instructions
The source provides specific dilution and application guidelines for the dyeing process: * Dilution Method: The full bag of goods should be dissolved into a 15-20% solution with de-ionized water. To alter the appearance to light yellow or brown, as required, 0.4-1 parts per thousand of a dispersing agent can be added. * Dyeing Process: Add water, then the levelling agent, and run for five minutes after adding the cloth. Begin the dyeing process thereafter. A clean reference ratio of 0.5-1g/l is suggested.
Commercial Terms and Free Sample Mention
The commercial terms listed are for business-to-business transactions. The product is sold in 25kg bags, which should be stored sealed airtight. Price is listed as negotiable, with no minimum order quantity (MOQ) specified. Payment terms include L/C, T/T, and Western Union. The country of origin is China, and the company is a manufacturer.
A crucial piece of information from the source metadata is the inclusion of "free sample" among the product's "Hot Tags." This indicates that the manufacturer may offer complimentary samples of the SY-1A levelling agent, likely for evaluation by potential industrial or business customers. However, the provided source material contains no further details regarding the free sample programme. There is no information on: * Eligibility criteria for requesting a free sample. * The application or sign-up process. * Any geographic restrictions (e.g., whether samples are available to customers in the United Kingdom). * Shipping policies or costs associated with sample delivery. * The size or quantity of the free sample offered.
Conclusion
The Direct Reactive Dyes Levelling Agent SY-1A is an industrial chemical product with defined specifications and application instructions for textile dyeing. The source data confirms the manufacturer's potential offer of free samples, as indicated by its inclusion in product tags. However, the documentation lacks the comprehensive details required to guide consumers or businesses on how to access these samples. For those interested in obtaining a sample for evaluation, direct inquiry with the manufacturer or supplier would be necessary to obtain the specific terms, conditions, and application procedures for their free sample programme.
